                                          Summary of Conclusions

                     Using field data (physical, chemical, biological) taken in the

                Apalachicola Bay system from March, 1972, to the present time, a review was

                made concerning the impact of dredging and the deposition of spoils on the

                Apalachicola estuary. For the most part, data analysis was conducted on

                fixed (i.e. permanent) stations, which has the advantage of identifying

                long-term effects in specific areas of the bay. However, the use of infor-

                mation that was not necessarily directly related to the dredging program in

                the Apalachicola system disallowed a precise evaluation of certain aspects

                of the dredging. Such effects include immediate (short-term) area- and

                event-specific responses of various portions of the estuary to individual

                dredging events.

                     The main dredging effort occurred within the Intracoastal Waterway

                although the opening of the two-mile channel (in 1976) and the contin ued

                dredging of Sike's Cut were considered to be important focal points of the

                overall analysis (from 1973 to the present). All dredging ceased in 1978,

                which, together with the two-mile channel opening or extension, constituted

                important events (or interventions) in the time-series analysis of the

                data. Seasonal cycles of important commercial species were reviewed in

                detail because of potential problems of dredging activities that could

                affect natural successions of estuarine productivity. Salinity effects

                were analyzed in some detail because of the central role of salinity in

                affecting biological productivity.

                     All evaluations had to be carried out within seasonal and annual

                cycles of river flooding and drought. A complete review of background eco-

                logical conditions at most stations over the study period revealed habitat

                                                    ii

                changes that were generally consistent with short- and long-term trends of

                climatological conditions. Several station-specific changes in the

                physical, chemical, and biological features of the estuary were related,

                directly or indirectly, with dredging activities:

                     1. Salinity at Sike's Cut was spatially and temporally related to

                dredging activities in the area. Prior to the 1978 cessation of dredging,

                there was considerable salinity stratification and generally high (stable)

                salinities at depth. From 1978 to the present, bottom salinities were

                generally lower despite periodic drought conditions, and various factors

                (salinity, dissolved oxygen) indicated less stratification of the water

                column as the cut filled in and cut off the movement of high-salinity water

                from the gulf into the estuary. Such salinity effects were translated into

                a local increase in species richness and diversity (as stenohaline gulf

                species penetrated the estuary) and a reduction of those organisms, many of

                the commercially valuable species, that usually utilize the estuary as a

                nursery (i.e., penaeid shrimp, blue crabs, finfishes). Such effects were

                supported by observed shifts in the biological (community) structure at

                Sike's Cut following the cessation of dredging in 1978. Preliminary sur-

                veys indicate that the area of impact is greater than that indicated in

                previous studies. This part of the study is continuing with an analysis of

                the distribution of salinity in Apalachicola Bay before and after the

                dredging of Sike's Cut in 1984.

                     2. No short-term effects of dredging were noted on various water

                quality factors and biological indices as a result of dredging operations

                in the Intracoastal Waterway and two-mile extension during winter months.

                     3. No significant long-term changes in habitat features were evident

                at stations that could have been affected by the opening of the two-mile

                extension in 1976. However, subtle (and statistically non-significant)

                changes in the biological response indicated altered conditions off Green

                Point relative to changes in the main (intracoastal) channel. The

                interpretation of increased freshwater input to the St. Vincent Sound area

                was thus not substantiated by statistically significant shifts in water

                quality (i.e., salinity) factors. However, long-term shifts in the biota

                indicate a diversion of fresh water to western sections of the Apalachicola

                estuary subsequent to the opening of the two-mile extension.

                     4. The dredged channels along the Intracoastal Waterway, the two-mile

                channel, and the East Point Channel created conditions for the con-

                centration of silt-laden sediment fractions and loading of specific

                (associated) contaminants such as heavy metals and organic matter.

                However, the propensity of such channels to act as sinks for such materials

                was dependent on various factors such as proximity to urban runoff, cir-

                culation conditions, and other seasonally adjusted variables. Infaunal

                benthic macroinvertebrate communities reflected such conditions and were

                adversely affected in certain portions of the East Point Channel and the

                two-mile channel. However, various areas along the Intracoastal Waterway

                and Sike's Cut were generally unaffected in terms of accumulations of con-

                taminated sediments. Thus, only those dredged areas that were proximal to

                contaminated storm-water runoff were characterized by contaminated sedi-

                ments and biological degradation. Location relative to land runoff and

                current structure are determinants of the impact of dredged channels in the

                Apalachicola estuary.

                                                    iv

                     5. Overall analysis of dredging activities in the Apalachicola

                estuary indicated that such operations can affect the salinity regime and

                biological productivity of the system. However, such effects are complex

                and depend on natural, long-term changes in the bay system and the exact

                nature of the dredging activity in terms of timing, location, and effort.

                Because the dredged channels of the intracoastal waterway serve as a nur-

                sery area for developing young of commercially important species such as

                penaeid shrimp during spring, summer, and fall months, dredging of the bay

                should be restricted to winter-early spring months (December-March), when

                habitat disturbance due to dredging is minimal.

                     This project was funded by the Florida Department of Environmental

                Regulati.on (Project Officer, Stephen Leitman) through a contract awarded by

                the department to the Florida State University (Robert J. Livingston,

                Principal Investigator, and the Aquatic Study Group). The objective of the

                study was to review existing field data concerning the Apalachicola Bay

                System taken continuously by the F.S.U. Aquatic Study Group from March,

                1972 to the present. A general review of the scope of the project, with

                appropriate scientific references, is given by Livingston (1983 a, b).

                     Field work has been carried out by numerous workers over the years

                (Livingston 1983 a). Data processing was carried out by the principal

                investigator with help from Glenn C. Woodsum, Loretta E. Wolfe, and Duane

                A. Meeter. Data transmission was accomplished by Shelley J. Roberts while

                J. Michael Kuperberg handled the administration of the grant. Additional

                information on dredging activities in the study area was provided by the

                U.S. Army Corps of Engineers (Mobile, Alabama) and Mr. Stephen Leitman

                (Florida State Department of Environmental Regulation; Tallahassee,

                Florida). Data analysis was carried out using software systems developed

                by the Aquatic Study Group in conjunction with the.Florida State University

                Computer Center.

                A. Environmental Setting

                     Livingston (1983, 1983a, b, c) has given a general review of the eco-

                logical background and socioeconomic character of the lower Apalachicola

                basin. The aquatic productivity of the estuary depends on three primary

                factors: (1) The Apalachicola River system which delivers dissolved and

                particulate organic matter and inorganic nutrients to the estuary while

                maintaining seasonally variable control of the salinity regime of major

                portions of the Apalachicola Bay system (East Bay, Apalachicola Bay, St.

                Vincent Sound, western St. George Sound; Figure 1). (2) Local rainfall and

                overland runoff from surrounding marshes, swamps, and wetlands. (3) The

                physiographic features of the system which include the shallow basin and

                enclosure by a barrier island system (mainly St. George Island and St.

                Vincent Island; Figure 1) which profoundly affect the current structure and

                salinity regime of the bay system.

                     Depths in the Apalachicola Bay System average 2-3 meters. Tidal

                ranges are relatively small, approximating 0.3-0.4 m at the highest tides.

                Such tides are unsymmetrical and semi-diurnal except during periods of high

                winds which tend to disrupt the usual tidal pattern and have a strong

                influence on the current structure of the system. Current velocities in

                the estuary average 1.5-2 feet per second although velocities near the

                passes (i.e. Indian Pass, West Pass, Sike's Cut; Figure 1) may reach 3 feet

                per second. Net flows tend to move to the west from St. George Sound into

                Apalachicola Bay where they merge with water moving out of East Bay (Figure

                2). There is a net westward flow through St. Vincent Sound; however, move-

                ment through Indian Pass may be retarded by the Picoline Bar. The major

                                                    2

                outlet for low salinity water out of the estuary is West Pass although wind

                and tides have a major influence on net outflows at any given time (Figure

                3).

                B. Effects of Dredging and Spoil Placement

                     The impact of dredging and spoil placement on the physical/chemical

                environment and biological structure of estuaries has been reviewed by

                various authors (Marshall, 1968; Odum, 1970; Lee and Plumb, 1974). Such

                potential general effects have been summarized by Darnell (1976) (Table

                1A). Specific categories of impact include alteration of bottom

                topography, modification of natural patterns of water circulation, altered

                water quality, and siltation effects because of the accumulation of fine-

                grained particles. Odum (1970) and others have alluded to the fact that

                sediments control various ecological factors in estuaries in terms of

                destabilization of the benthic habitat and the tendancy of fines to be

                associated with high organic concentrations, oxygen depletion due to high

                biochemical oxygen demand (B.O.D.) and high chemical oxygen demand

                (C.O.D.), and the concentration of toxic pollutants (i.e. oil and grease,

                organic materials, metals) due to absorption of such materials to the sedi-

                ments (Fines). These trends are evident in bays and estuaries (Table 1B)

                where sedimentation rates from overland runoff can be particularly high.

                Areas where marshes are effected can also suffer impacts due to dredging

                and spoiling (Table 2). Darnell (1976) has given a detailed synopsis of

                the combined effects of dredge/spoil activities in bay systems (Figure 4)

                which illustrates potential problems to be examined when analyzing the

                impact in any given area.

                                                    3

                     Since the early review of the problem, considerable research has been

                carried out to address specific effects of dredge/spoil activities in areas

                outside and within the Apalachicola estuary. The location of the dredging

                activity is important to the overall impact. Water from highly con-

                taminated disposal sites can be toxic to larval organisms when compared to

                the dredge site proper or areas removed from the dredge site (DeCoursey and

                Vernberg, 1975). However, Hoss et al. (1974) showed that such effects from

                contaminated sediments are species-specific, and Sissenwine and Saila

                (1974) demonstrated that dredge and spoil effects may have no demonstrable

                effect on finfish fisheries in the general area of operations.

                     On the other hand, dredging in upland areas to form isolated canals

                can have profound adverse effects on water quality, sediment quality, and

                the natural (biological) productivity of an estuary (Kaplan et al., 1974;

                Lindall et al., 1975; Adkins and Bowman, 1976). Likewise, dredging and

                filling can have a direct, adverse impact on grassbeds (Briggs and

                O'Connor, 1971) and shellfish (Mackin, 1961; Rose, 1973) in the immediate

                vicinity of the dredging operation. Such effects may be localized (Ingle,

                1952) and specific to a given environmental situation and may depend to a

                considerable degree on the timing and form of the dredging operations

                (Mackin, 1961). Field observations in some estuaries indicate that sedi-

                ment resuspension due to dredging.may be similar to that due to natural

                changes induced by storms (Bohlen et al., 1979) so that an impact analysis

                should be carefully designed to include the natural background variation of

                environmental factors in the specific estuary in question.

                     Various studies have been carried out in the general region (i.e., the

                northeast Gulf of Mexico and surrounding areas). Subrahmanyam and

                                                     4

                Kruczynski found that man-made islands (from dredge spoil) in Dickerson Bay

                (north Florida) were rapidly colonized by polychaete worms due primarily to

                immigration from surrounding areas. Lee and Jones (1982) showed that con-

                taminants such as heavy metals, organochlorine pesticides, and nutrients

                attached to sediments generally were not released to an appreciable degree

                to the associated water column. Conclusions were drawn from elutriate

                tests that open water disposal of contaminated sediments from a Texas

                estuary would not cause a significant adverse impact on water quality in

                the Gulf of Mexico. According to a study for the U.S. Army Corps of

                Engineers (Water and Air Research, Inc., 1975), maintenance dredging in

                Apalachicola Bay in 1974 had no significant effects on water quality,

                plankton, coliform bacteria, or benthic invertebrates. According to this

                study, natu.ral disturbances (weather, wind, floods) had greater affects on

                levels of suspended solids and turbidities than dredging and no metals or

                coliform bacteria were released to the water column. Benthic invertebrates

                suffered only localized, short-term effects in the channel and on spoil

                banks; elsewhere, the bay was unaffected by maintenance dredging during the

                winter or early spring. This study was based on short-term data ("before

                dredging . . . after dredging"; February-July). General reviews of

                dredging activities in the region are given by the U.S. Army Corps of

                Engineers, Mobile District (1976, 1981).

                     Taylor (1978) evaluated the effects of dredging and open water dispo-

                sal on 28 sites along the Gulf Intracoastal Waterway from Apalachicola Bay

                to Lake Borgne, Florida. Four sites along the Intracoastal Waterway in

                Apalachicola Bay were analyzed. Taylor (1978) dismissed the accumulation

                of silt and clay in disposal areas as not significant. It is somewhat

                                                    5

                difficult to make a detailed comparison of data taken only once at dif-

                ferent times (i.e., November, 1977-February, 1978) at the various sites

                along a relatively broad area of study. Benthic infauna were comparatively

                rich at 2 of the Apalachicola sites. However, according to the overall

                totals, channel stations were relatively depauperate (2,251 individuals)

                relative to spoil stations (8,057) and undredged areas (9.357 individuals).

                The most depauperate macroinvertebrate fauna were usually noted in channels

                at sites 1, 2, and 3 in Apalachicola Bay relative to spoil sites and

                undredged areas. All four sites in Apalachicola Say were considered

                "environmental sensitive due to the proximity of oysters and seagrass

                beds."

                     This study was carried out during winter periods when stress from high

                temperature and low dissolved oxygen is minimal. Taylor (1978) indicated

                that, although channel maintenance dredging operations are in most instan-

                ces disruptive, such alterations are "localized" and "largely temporary."

                However, because of the relatively limited sampling effort in any given

                area, such conclusions may not be applicable to all the portions of the

                survey area. In addition, impact based on system-wide alterations (i.e.

                current structure, salinity) due to dredging could escape detection because

                of the limited scope of the sampling. The relatively limited scope of the

                Taylor study in any given area simply disallows broad conclusions con-

                cerning the impact on dredging and spoil deposit operations on the aquatic

                areas in question. A review of the scope of the problems associated with
                dredging activities has been given by Darnel'l (1976).

                     Zeh (1979) and Mehta and Zeh (1980) have studied the impact of Sike's

                Cut on Apalachicola Bay. The authors concluded that the maximum influence

                                                    6

                of the inlet on the bay may be expected to occur during spring tides. Such

                influence was considered to be."fairly localized" and existing oyster reefs

                in the bay to be well away from the influence of the inlet on the bay.
                A. Station Placement    H. Methods and Materials

                     General descriptions of the various methods of field analysis of phy-

                sical, chemical, and biological features of the Apalachicola estuary are

                given by Livingston (1978, 1980, 1983) and Livingston et al. (1976).

                Station locations for detailed spatial relationships (Figure 1; Livingston,

                1983b) and long-term studies (Figure 5; Livingston, 1978) allowed various

                forms of analysis of the multidisciplinary data base. Such data have been

                used for this report.

                     A series of 55 stations were established in the lower Apalachicola

                River system (including various tributaries and creeks), East Bay,

                Apalachicola Bay, St. Vincent Sound, and western St. George Sound (Figure

                1). Stations were designated in the following way:

                    1.  All Apalachicola River system stations were marked with the
                        prefix "R."

                    2.  All stations that were permanent collection areas in the long-
                        term analysis (12 years) of the Apalachicola system by the FSU
                        research group were given their established numbers (1, 1A,
                        1B, 1C, IX, 1E, 2, 3, 4, 4A, 5, 5A, 5B, 6).

                    3.  New East Bay stations were marked with the prefix "E."

                    4.  New St. Vincent Sound stations were marked with the prefix
                       It V. It

                    5. New  Apalachicola Bay stations were marked with the prefix "A."

                    6. New  St. George Sound stations were marked with the prefix "G."

                                                     7

                    A detailed breakdown of exact station locations is given in Table 3.

                B.  Chemical Methodology (water, sediments)

                     Specific scientific methods used over the long-term research effort in the

                Apalachicola Bay system (Figure 1) have been given in a series of publications

                (Livingston et al., 1974, 1976, 1977, 1978; Livingston, 1975a, 1976  a, b, c, d,

                1979a, 1981; Livingston and Duncan, 1979; Livingston and Loucks, 1979; Meeter

                et al., 1979; White et al., 1979), and such details will not be reviewed here.,

                A parallel group of publications has outlined various management approaches

                used in conjunction with the scientific effort (Livingston, 1975b, 1976b-e,

                1978, 1979a,, b. 1980, 1981, 1982a, b, 1983; Livingston and Joyce, 1977;

                Livingston and Loucks, 1979; Livingston et al., 1974, 1976, 1977, 1978, 1982).

                Livingston et al. (1974) outlined the key features of the tri-river drainage

                system (Figure 2) and listed various potential  and real problems of development

                with suggestions for management initiatives to protect the resources associated

                with the Apalachicola valley. Livingston (1975b) listed the various state and

                federal laws and regulations pertaining to environmental problems in aquatic

                areas with application to the Apalachicola situation. The methods of analysis

                that relate salinity to various biological processes in the Apalachicola

                estuary is given by Livingston (1979a).

                     1. Water Quality

                     Water samples (surface and bottom) were taken at all fixed stations

                with a I-liter Kemmerer bottle. Temperature and dissolved oxygen were

                measured with Y.S.I. dissolved oxygen meters. Salinity was determined

                with a temperature-compensated refractometer calibrated periodically with

                standard sea-water. Turbidity was taken with a Hach model 2100-A

                turbidi-meter. Apparent color was analyzed with an      American Public

                                                      8

                Health Association platinum-cobalt standard test.    Light penetration was

                estimated with a standard Secchi disk, and water depth was routinely moni-

                tored at each sampling site. The pH was measured with portable pH meters.

                The date and time, along with appropriate field notes, were recorded at

                each sampling station.

                     To collect other samples for water quality analysis, a sterile plastic

                bag was used. Each collection included at least 100 ml of sample. Sample

                containers were not filled completely; an air space of at least one-fourth the

                total volume was maintained. According to established procedures, samples

                that were not analyzed immediately were placed on ice or refrigerated (1-40C)

                and analyzed within six hours or less. Sterile sample containers were filled

                below the surface of the water; a sweeping motion was used and the open end of

                the container was kept in the direction of the sweep. Chemical oxygen demand

                (Hach system, EPA-approved), biochemical oxygen demand (Standard Methods, 15th

                edition), oils and greases (Standard Methods, 15th edition, partition-

                gravimetric method), fecal coliforms (Hach multiple-tube fermentation tech-

                nique, EPA approved), N03-N (Standard Methods, 14th edition, Brucini method),
                and P04-P (Standard Methods, 15th edition, ascorbic acid method) were analyzed

                using standard laboratory techniques. A Bausch and Lomb Spectronic 2000

                spectrophotometer (double beam, 2 nm slit width) was used for all measurements.

                     2. Sediments

                     Sediment analyses were carried out at all 55 station locations (Figure

                1).  Granulometric analyses were run on a well mixed 10-cm core sample from
                each station. Corer dimensions are 76 mm diameter and 45 cm2 cross-sectional

                area. Unpreserved sediments were divided into a coarse (> 62 micrometers)

                and a silt-clay (< 62 micrometers) fraction. The coarse fraction was

                                                    9

                analyzed by wet sieving using 1/2-phi-unit intervals. The silt-clay fraction

                was analyzed using a pipette method in 3/2-phi-unit intervals from 4 phi to 6

                phi and in 1-phi intervals for finer fractions (6 phi to 10 phi). Percent

                organics were determined by ashing in a muffle furnace for 1 hour or more

                at temperatures approximating 500-5500C.

                     For chemical analyses, all core samples were taken and transferred to

                clear plastic containers. Only 6 g dry weight of sample were needed for

                PIXE (proton-induced X-ray emission) analysis. We collected enough

                sediment for 10 g dry weight. Samples were taken to the F.S.U. Marine

                Laboratory for drying, which was accomplished in clear plastic Petri dishes

                covered with kim-wipes after removal of water by means of a press. Dry

                samples were then delivered to Element Analysis Corporation (Tallahassee,

                Florida). The PIXE methodology was used as a rough scanning approach
                (accuracy, � 10%; precision, � 5%; H C. Kaufmann, personal communication).

                With sediment samples, certain metals such as cadmium, barium, arsenic,

                tin, and mercury were listed as "less than" a certain value. Such figures

                can only be considered as tentative and cannot be taken as absolute values

                without more detailed analysis. Again, this method was used as a broad,

                range-finding approach, which should be followed up with more intensive

                chemical (analytical) methodology. Shallow sediment temperature and sali-

                nity did not differ substantially from our bottom water measurements and

                were not listed separately.

                     Apalachicola River flow data (Blountstown, Florida) were provided by

                the U. S. Army Corps of Engineers (Mobile, Alabama). Rainfall data were

                provided by the National Oceanic and Atmospheric Administration

                (Apalachicola, Florida) and the East Bay tower station of the Florida

                                                     10

                Department of Agriculture, Division of Forestry (Tate's Hell Swamp, near

                the Sumatra road in Franklin County).

                C. Biological Methodology

                     Previous analyses (Livingston, unpublished data) indicated that 10
                core samples (76 mm diameter, 45 cm2 cross sectional area, 10 cm depth) are

                adequate for a representative sample of benthic infaunal macroinvertebrates

                at each station. All samples were sieved through a 0.5-mm sieve. Each

                sieve fraction was preserved with 10% formalin and stained with Rose Bengal

                to facilitate picking. The samples were elutriated where necessary (if

                there was any heavy sand or shell residue) and all individuals removed for

                counting and identification to species under a dissecting microscope.

                Preliminary analyses of the data indicated that the following biological.

                indices of the data would be used:
                    1.  Number of individuals per M2 (density)

                    2.  Total number of individuals (per sample)

                    3.  Species richness (total number of species per sample)

                    4.  Brillouin species diversity

                    5.  Brillouin evenness (equitability)

                    6.  Hurlbert's diversity

                     River/marsh areas were sampled for fishes with seines during the first

                four years of study. Offshore stations were sampled at night with. gill and

                trammel nets (2.5-cm mesh) and during the day and at night with 5-m otter

                trawls (1.9 cm mesh wing and body; 0.6 cm mesh liner). Two to seven repeti-

                tive 2-minute trawl tows were taken at various stations at speeds approxi-

                mating 2-2.5 knots on a.monthly basis from 1972 to present. The number of

                samples necessary for species accumulation curves exceeding 90% were

                determined by methods similar to those described by Livingston et al.

                (1976). All animals were preserved immediately in 10% buffered formalin,

                sorted, identified to species, counted, and measured (standard length).

                Larger predators and game fishes were also taken with hook and line and by

                examination of catches made by sports fishermen at a local fish camp.

                D. Statistical/Computational Methods

                     All calculations involving fishes and invertebrates were based on num-

                bers of individuals. Matrices of all variables were developed according to

                system, date, and station. Storage, retrieval, and analysis were performed

                with an interactive computer program (SPECS, MATRIX; Woo dsum and Wolfe,

                1983). Where necessary, skewness and kurtosis were estimated to assess the

                reasonableness of the assumption of normality. Log and square root trans-

                formations of the data.were made as indicated. A detailed review of the

                use of such techniques is given by Livingston (1975), Livingston et al.

                (1978), and Meeter and Livingston (1978). All cluster analyses were run

                using various similarity coefficients.

                     The,Bray-Curtis index of similarity, which has been shown to be an

                effective device for discriminating clusters of animal groups, has been

                applied here to identify groups of locations based on similar charac-

                teristics across a number of variables. The index is defined as

                           n
                               xi - yi

                           n
                              (xi - yi)

                where

                                                        12

                       xi = value of ith variable at location one, and
                       yi = value of ith variable at location two.

                  The index is designed to range between zero and one, and for this to be

                  true, the rel ati onshi p
                       0 <   xi - yi                                                        (2)
                             -Xi + y i   <

                  must hold for each variable.

                       It is apparent from (1) that the scales upon which the variables are

                  measured have an important influence on the relative contribution each

      W           variable makes to the overall index. Looking at the denominator of the

                  second term above, it is apparent that a variable whose values range from

                  100-280 will contribute at least 200 to this sum while a variable whose

                  values range  from 0-0.85 can contribute at most 1.70. Thus the effect of

                  this second variable, relative to the first, is practically non-existent.

                       To overcome this scaling difficulty prior to the application of (1), a

                  different line of analyses was developed. A commonly used method of

                  rescaling a variable is the "normalization" procedure, was used to trans-

                  form the value set into a new set with mean zero and standard deviation

                  one:
                       xi     (xi - X)                                                        (3)
                                S

                  where

                       x is the mean of the value set, and

                       s is the standard deviation.

                  This transformation cannot be used in conjunction with     the Bray-Curtis

                  index, however, because the restriction imposed by inequality (2) above may

                                                       13

                 not be satisfied. To solve this problem, we considered the case where, for

                 variable 1, the value at one location was one standard deviation above the

                 mean (xi = +1) and at another location the value was one standard deviation

                 below the mean (yi    -1). Here
                        xi - yi I      i - (-l)j-        2
                      (xi + Yi T_        +  (-I)

                 which is  undefined.

                      Another approach was used to transform each variable so that its
                 values range between zero and one (Spa**th, 1980). This is accomplished as

                 follows:
                      xiii     xi   Xmin                                                     (4)
                              Xmax   Xmin

                 where

                      xmin    minimum value found for this variable, and

                      xmax    maximum value found for the variable.
                 Thus the transformed value (xi") becomes zero for the smallest observation
                 (xi = xmin) and one for the largest observation (xi = xmax), and inter-

                 mediate values occupy the same relative positions within the new range as

                 they did in the original range.

                      This method of rescaling imposes a common scale to all variables and

                 ensures equal consideration of all variables in the ca    lculation of the

                 similarity index. However, truly equal consideration of all variables may

                 not be desirable if one of the measured variables is a quantity that varies

                 little from  one location to another, its coefficient of variation (C) is

                      C = S/x                                                              (5)

                 where s is the sample standard deviation and x the mean, and may be quite

                 low. If a second variable differs more from site to site and has a

                  relatively high coefficient of variation, the following data set is

                  possible:

                                                                        Rescaled V,      Rescaled V2

                                    -il = 6           -R2 = 6           il      .5        x2" =    .5
                                    sl = 0.816        S2 = 2.582        s," =  0.408       S2" = 0.323
                                    C1 = 0.136        C2 = 0.43         Cl" =  0.816      C2" =  0.646

                  Thus, the greater initial variability of the second variable (C2 > Cl) has
                  been lost following data transformation (Cl > C2) while the relatively
                  higher variability of V, will mean that V, becomes the more "important'

                  variable in discriminating clusters of locations. This means that there is

                  an artificial exaggeration of the importance of V1. Based on the actual
                  values above it seems likely that V2 would be the more "useful" variable in

                  attempting to distinguish clusters of locations. We have developed an

                  adjustment to this rescaling procedure that minimizes the above difficulty.

                        We therefore would define the "relative coefficient of variation" for

                  variable k as

                                                        15

                               Crk = CklCmax                                         (6)

                 where Ck is the coefficient of variation (5) and Cmax is the largest

                 coefficient of variation found for all variables used. We would then

                 adjust the rescaled values computed according to (4) by

                      xik" = (CRk - xik")   + (1 - CRO/2                                   (7)

                 The first term of (7) permits a transformed variable to range only in pro-

                 portion to its original coefficient of variation. Thus the only variable

                 allowed the full 0 to 1 range in its transformed state is that variable

                 with the highest original coefficient (Ck = Cmax). The second term of (7)

                 adjusts the range of each rescaled variable so that its mid-range point is

                 0.5. If we apply (6) and (7) to the data values of the sample data set

                 above we find that CrI = 0.316, Cr2 = 1, and that the adjusted rescaled

                 values are

                                          V1            V2

                                        0.5             .5

                                        0.66            .75

                                        0.34            1

                                        0.5             0

                                        0.5             .25

                                        0.34            .5

                                        0.66            .5

                 The values of V1 have still been placed in a scale compatible with that of

                 V2, but they have been placed in a better perspective when considering the

                 original amounts of variation.

                                                    16

                     This adjustment is sensitive to outliers because they can increase the

                coefficient of variation for a variable, thereby increasing the likelihood

                that it will be selected as Cmax in equation (6). One must examine the

                data prior to the application of this method, therefore, and possibly make

               .other data transformations (e.g. logarithms) prior to its use. One might

                also perform initial transformations if a linear relationship is found to

                exist between the mean and standard deviation of the variables to be used

                in the analysis.

                     The ANOVA results will be analyzed later in this report (see Results

                and Discussion). When analyzing salinity at each station, it is important

                to consider the effects of riverflow and rainfall. A significant dif-

                ference between the during and after dredging mean salinities may reflect

                the influence of a flood more than a true dredging effect. Analysis of

                covariance (ANCOVA) is helpful in eliminating this problem. ANCOVA assumes

                there is a linear relationship between the dependent variable and each

                covariate. Using a combination of regression and analysis of variance

                techniques, the effects of the covariate(s)  (riverflow and rainfall) are

                removed and the residuals analyzed for the effect of the treatments on

                salinity.

                                           III. Ouestions Asked

                     The salinity regime of the Apalachicola estuary is critical to the
                -form and processes concerned with the productivity of the system

                (Livingston, 1983). Relatively little information is available concerning

                the long-term effects of dredging on estuarine salinity and, consequently,

                the biological organization of the system. Accordingly, the established

                data base was used to address the following questions:

                                                    17

                     1.  Has there been a change in the salinity regime in the estuary
                         related to cessation of dredging activities in 1978?

                     2.  Has there been a change in the salinity regime related to creation
                         of 2-mile extension channel in 1976?

                     3.  Is the salinity at Sike's Cut different from that of the rest of
                         the bay? If it is different, to what extent has the bay been
                         affected by the opening of Sike's Cut?

                     4.  Are animal populations and communities at Sike's Cut different
                         from those in the rest of the bay?

                     5.  Have there been changes in animal populations or communities
                         related to cessation of dredging or the 2-mile extension work?
                     6.  Do specific dredge/disposal events cause any observable short-term
                         changes in turbidity, color, or dissolved oxygen?

                     7.  Do specific dredge/disposal events cause any observable short-term
                         changes in animal populations or communities?

                     Specific events will be evaluated such as the pattern of maintenance

                dredging at Sike's Cut and the Intracoastal Waterway from the mouth of the

                Apalachicola River to the boundary between Apalachicola Bay and St. George

                Sound (Figure 1). The opening of the two-mile extension in 1976 will also

                be analyzed in terms of possible changes in salinity and other factors such

                as biological response to potential shifts in the movement of fresh water

                within the estuary.

                                        IV. Results and Discussion

                A. Dredging Activities

                     A detailed chart of dredge spoil sites along the two-mile channel, the

                Intracoastal Waterway, Sike's Cut, and the East Point-Channel is given in

                Figure 6. Daily disposal volumes (in cubic yards) by site from 1970 to

                present are given in Table 4 and Figures 7-11. Monthly totals of the

                dredging effort in Apalachicola Bay from 1970 to present is given in Table

                5 and Figure 12.

                     Most of the dredging, almost 4 million cubic yards, occurred within

                the Intracoastal Waterway. The two-mile channel and extension were second

                and third, respectively, in spoil volumes followed by Sike's Cut and the

                East Point Channel (Table 5). Most of the dredging activity in the bay

                took place from November through March with certain notable exceptions.

                Sike's Cut was dredged during late spring or summer months in 1971, 1975,

                and 1978. The Intracoastal Waterway was dredged in April 1977 and from

                April to June in 1978; activity in April 1978 was concentrated at sites 9

                to 11 (our station 1C) (Table 4). During May, 1978, most of the dredging

                occurred at disposal sites 1-4. In June, 1978, such dredging took place at

                site 1A (near our Station 2). Dredging in the two-mile channel was per-

                formed in April, 1978 with disposal at sites 1-4 and 8. The two-mile

                extension was dredged during March and April, 1976 (Table 4). No dredging

                occurred during 1973 and the most active dredging periods took place during

                1970, 1976, and 1978 (Figure 12). No dredging in Apalachicola Bay has

                taken place since 1978.

                                                    19

                     Specific interventions, to be used in statistical tests, occurred as

                follows:

                         1.  Sike's Cut Site; dredging ceased in 1978 (up to this point in
                             time, Sike's Cut had been routinely dredged from year to
                             year).

                         2.  Intracoastal Waterway; spring-summer dredging, 1978.

                         3.  Two-mile extension; spring, 1976.

                         3.  Overall cessation of dredging; 1978.

                The above interventions were chosen for either of two reasons: landmarks

                of dredging activity (newly dredged area, two mile extension, 1976; cessa-

                tion of dredging, baywide, 1978), and deviations from the usual winter

                dredging (summer dredging in the Intracoastal Waterway, 1978).

                B. Climatological Factors

                     Since the distribution of salinity in space and time is considered as

                a major ecological variable (Livingston, 1983), specific climatological

                features which influence salinity (i.e., Apalachicola River flow and local

                rainfall) have been analyzed.

                    1. River Flow

                      In terms of calendar year totals for river flow (Table 6), the

                highest annual river flows occurred in 1973 and   1975, with secondary high

                levels in 1976 and 1979. The lowest river flow was noted in 1981. A clus-

                ter analysis of these data (Figure 13) indicates that 1981 (an extremely

                                                     20

                dry year) was differentiated from a cluster of the years 1973, 1975, 1976

                and 1979, the so-called wet years.  Monthly variation within a given year

                was highest in 1973 and 1980 which  indicates strong differences between the

                winter-early spring flooding and the rest of the year. These generaliza-

                tions are graphically displayed in Figure 14. Winter and/or spring peaks

                are particularly noticeable during 1973 and 1980. Such peaks follow pat-

                terns which are quite similar (Figure 13), which is in line with long-term

                analyses indicating 6-7 year cycles of peak river flow (Meeter et al.,

                1979). The period from late 1980 through 1981 represents a major drought

                in the region (Table 7) which adds to the observation that 1981 was an unu-

                sual water year. Low flows were also observed during the fall of 1972 and

                1974 (preceding the winter-spring floods) while the peak flow of 1980 was

                followed by the major drought of 1980-81.

                2. Rainfall

                     Local rainfall depends, in part, on prevailing wind conditions in the

                region, According to long-term trends (National Oceanic and Atmospheric

                Adminstration, Apalachicola, 1982), about 75% of the annual number of thun-

                derstorms occur during the summer months, and September is the wettest

                month of the year, on average, over the period on record (1943-present).

                Prevailing winds usually come from the northeast or north from September

                through February and from the southeast, southwest, or west from March

                through August.

                     Listings of local rainfall (East Bay, Apalachicola) are given in Table

                7, and graphical representations of the data are given in Figures 15 and

                16. Although the general pattern of long-term rainfall was similar-in East
                Bay (i.e., Tate's Hell Swamp) and Apalachicola, higher rainfall totals

                                                    21

                occurred generally at the Tate's Hell site. The highest summer peaks

                were noted in 1974-1975 and 1979, following an approximate five year

                periodicity of local rainfall as noted by Meeter et al. (1979). Drought

                periods were noted in 1972, from 1976 to 1979, and from 1980 to 1981.

                Local rainfall was generally low during the major river flooding of 1973

                which indicates that local rainfall is not only seasonally different from

                river flow patterns but differs on a multi-year basis as well (see Meeter

                et al., 1979, and Livingston and Loucks, 1979, for a more complete

                discussion of the relationships between temporal patterns of Apalachicola

                river flow and local rainfall).

                     Cluster analyses of local, annual trends (by year) are given in Figure

                17. The general trends, as described above, are shown in both dendograms;

                drought years (1972, 1976; 1977, 1981) were clustered together as were

                periods of high rainfall (1974, 1979). The overall patterns of rainfall in

                the respective study areas were similar.

                C. Physical/Chemical Environment

                     The raw data for physical/chemical factors are given in Table 8 and

                Figure 18.  Certain general trends were evident throughout the estuary.

                The major river flooding during the winter of 1973-74 was associated with

                high turbidity and color. The relatively low temperatures during the

                winter of 1976-1978 were generally associated with high dissolved oxygen

                levels throughout the bay. While some station to station variability is
                evident' such trends tend to be consistent in most portions of the study

                area, based on well recognized physical-chemical relationships (Livingston,

                1983).

                     There was relatively little temperature stratification at stations 1,

                2, 3, 5, 1A, 1B, and 1C (Figure 18). Seasonal ranges approximated 20-300C

                depending on the year. Spatial temperature distribution during any given

                time period was relatively uniform throughout the bay. When temperature

                stratification was noted, bottom temperatures tended to be lower than those

                at the surface, although this was not always the case at stations 1A and

                1B. At Sike's Cut (1B), bottom temperature was usually higher than surface

                temperature from 1972 to 1977. After 1977, bottom temperatures tended to

                be cooler than surface temperatures.

                2. Dissolved Oxygen

                     Generally, bottom dissolved oxygen was lower during warm months; stra-

                tification of dissolved oxygen (lower at depth) was observed at stations 1,

                2, 3, 5, 1A, 1B, and 1C. The grassbed areas (N) showed generally higher

                levels of dissolved oxygen at depth (especially from 1974 to 1978).

                However, at Sike's Cut, dissolved oxygen was more stratified vertically

                from 1972 to 1978 than after 1978; from 1978 to 1982, surface dissolved

                oxygen tended to be lower and bottom dissolved oxygen tended to be higher,

                a situation which indicated increased vertical mixing after 1978.

                3. Color

                     Color levels tended to reflect peaks of river flow at those stations

                influenced by river input. Color levels were highest in East Bay (Station

                5) and lowest at stations along St. George Island in Apalachicola Bay (1A,

                1B, 1C, 1X).

                                                     23

                4. Turbidity

                     Turbidity also followed river flow conditions seasonally and among

                years. Bottom turbidity was usually higher than surface turbidity.

                Following the high turbidities observed during the major flooding of 1973,

                there were bay-wide reductions of this factor from 1974 to 1976. Turbidity

                at most stations increased from 1976 to 1979-80 and was quite low during

                the drought of 1981. Turbidity was a good indication of river flow

                throughout the Apalachicola estuary.

                5. Depth/Secchi Depth

                     Secchi readings represent a simple though direct integration of the

                effects of color and turbidity on light penetration in a body of water.

                Secchi depth estimates were highest at those stations that were farthest

                from the influence of the river. There was a tendancy for Secchi depths to

                be deeper during periods of drought.

                     Depth readings at some stations tended to be somewhat more uniform

                during certain years than might be reasonably expected. Consequently, this

                factor can only be considered as a general indication of station depth.

                The deeper areas include stations 2, IB and 1C. The change in depth at

                station 1X between 1977 and 1978 could indicate  an inadvertent shift in

                station location during that period. A careful   review of this possibility

                indicated that, except for station IX, station locations remained rela-

                tively stable over the period of study.

                6. Salinity

                     Salinity in the Apalachicola estuary (Table 9, Figure 19) is

                influenced by various factors such as depth, wind, tidal currents, phy-

                siography of the basin, river flow, and local rainfall (Livingston, 1983,

                                                     24

                unpublished data). Certain generalizations are apparent from a cursory

                review of the data. Salinity was higher at depth at most stations and all

                of the study areas showed at least some salinity stratification at various

                times. There was considerable spatial and temporal variability of salinity

                throughout the estuary. Stations receiving direct river input (2, 3)

                followed the overall seasonal and long-term patterns of Apalachicola river

                flow.

                     The trend at Sike's Cut (1B) showed a basic shift in surface and bot-

                tom salinity with time. After 1978, bottom salinities were generally lower

                while surface salinities were higher. These observations will be analyzed

                in more detail later in this report. Because of the importance of salinity

                as a determinant of the biological organization of the estuary and because
                of the complexity of contributing facto*rs which determine the distribution

                of salinity in space and time, an expanded analysis of this factor was

                carried out relative to known patterns of dredging in the bay.

                a. Long-term Trends: Seasonal Averages

                     To present a less cluttered view of long-term salinity trends, season-

                al averages of salinity (surface and bottom) were computed at the various

                permanent stations in the Apalachicola estuary (Figure 20) and compared
                with seasonal trends of river flow and rainfall (Table 10). While the

                general trends (as observed above) were apparent (i.e., high salinity in

                1972, reduced salinity from 1973-1975, increased salinity from 1976 through

                1981, and reduced salinity from 1982 to the present), certain station-

                specific trends were apparent. Bottom salinity at station 2 was generally

                lower from 1978 to 1983 than the previous 6 years. Bottom salinity at sta-

                tion 1B was relatively stable from 1972 to 1978; such salinities at depth

                                                    25

                tended to be 1-ower after 1978. Surface salinities, however, were generally

                low from 1972 to 1978 after which time, there was a decided trend to higher

                salinities. The considerable stratification during the earlier period was

                not evident at Sike's Cut subsequent to 1977-78. At West Pass (1A), this

                pattern was not evident and bottom salinities were, within the usual seaso-

                nal ranges, relatively stable over the sampling period.

                     Monthly determinations of salinity (surface, bottom) were run through

                a Pearson Correlation analysis with rainfall and river flow values to see

                if there was a linear relationship for analysis of covariance (Table 11).

                A significant (p < 0.01) negative correlation was made between salinity and

                river flow at each of the bay stations indicating that only river flow and

                salinity have a linear relationship.

                     Another analysis was made to determine the relative influence of river

                flow and rainfall on salinity at the various stations. A significant dif-

                ference between observations before and after cessation of dredging in 1978

                could reflect river flow trends rather than the pattern of dredging in the

                bay. Analysis of covariance (ANCOVA) is helpful in eliminating this

                problem since use of ANCOVA includes the assumption that there is a linear

                relationship between the dependent variable and each covariate (Bryant and

                Paulson, 1976).

                     Using a combination of regression and analysis of variance (ANOVA)

                techniques, the effects of the covariates (i.e. river flow, rainfall) are

                removed and the residuals can then be analyzed for the effect of the treat-

                ment (i.e. cessation of dredging) on salinity trends at the various sta-

                tions. When scatterplots of the dependent variable (salinity) are run on

                each covariate (transformed to achieve normality), an evaluation of the

                                                     26

                linear relationships is possible. If a random scatter of points is found

                (as was the case with rainfall), the covariate is dropped from analysis and

                the ANCOVA is run with the remaining covariate (i.e. river flow) (Table

                12). If the p-value is less than or equal to a selected level of signifi-

                cance (0.05), the slope of the line relating salinity and the covariate can

                be considerably.different than zero. The F-tests for the factors and

                interactions are adjusted for the covariates so that, if a treatment effect

                is significant, it is not due to the covariate (i.e., the river flow).

                     The results (Table 12) indicate significant month by year interactions

                at all stations. However, surface/bottom salinity by month interactions

                were significant at stations 1B and 2 and surface/bottom salinity by year

                interactions were significant at stations 1B, 1C, and 2. Thus, some factor

                other than river flow is influencing the salinity at dredged stations (1C,

                2) and an area near a dredge operation (B).

                D. Short-term Responses to Specific Dredging Events

                     An analysis was made concerning short-term response of physical, che-

                mical, and biological (i.e., epibenthic fishes  and invertebrates) factors

                to specific dredging and storm events in the Apalachicola system.

                Livingston and Wolfe (1983) found that specific storm events do have a

                short-term (days to weeks) effect on benthic infaunal macroinvertebrates.

                Such effects are part of the natural response of shallow bodies of water

                such as the Apalachicola estuary to the effects of short-term increases in

                wind velocity in the region. A complete history of dredging events in the

                vicinity of our sampling stations is given in Table 13. Wind speed factors

                from 1975 to 1978 are given in Table 14.

                                                      27

                 1. Two-mile Extension (station 1)

                      Primary dredging events near station I occurred from 3/7/75 to 3/31/75

                 and from 4/1/76 to 4/31/76 (Table 13). Wind speeds were high on 3/18/75

                 (Table 14). Surface and bottom physical-chemical data for station 1 from

                 1975 through 1978 are given in Figures 21 and 22. As noted previously, the

                 salinity at station 1, subsequent to the opening of the two-mile extension

                 in 1976, did not go up as it did at most stations in the Apalachicola

                 estuary as a response to less overland runoff to the estuary during the

                 latter 1970's. No overt changes (at the surface or bottom) of temperature,

                 salinity, turbidity, color, or dissolved oxygen were apparent at station 1

                 during or after the dredging in 1976 or the storm in 1975. No short-term

                 effects of dredging were noted for any of the biological indices for fishes

                 (Figure 23) or invertebrates (Figure 24) at station 1. Dominant popula-

                 tions of fishes and invertebrates (Figure 25) did not appear to respond to

                 the dredging activities over the period of sampling. There were increases

                 in the numbers of spot (Leiostomus xanthurus), anchovies (Anchoa

                 mitchilli), and possibly blue crabs (Callinectes sapidus subsequent to

                 1976, but such changes could not be related to the dredging activities

                 around station 1. Wind effects (Table 14) over the short-term were noted

                 in terms of color and turbidity in the estuary (Table 15). Depending on

                 the direction and velocity, win.d appears to have immediate and substantial

                 effects on color and turbidity in the Apalachicola estuary.

                 2. Intracoastal Waterway (Station 2)

                      Changes in the physical, chemical, and biological factors (described

                 above) at station 2 (1975-1978) are given in Figures 26-27. No immediate

                 effects of dredging on physical, chemical, or biological factors were

                                                   28

               apparent at station 2 over the study period (Figures 28-29). The usual

               seasonal fluctuations were relatively stable from year to year, although

               salinity was elevated in 1977 relative to previous years. The storm could

               not be associated with any alterations in seasonal and annual trends of the

               data. Numbers of spot (Figure 30) were higher during 1978. Penaeid shrimp
               (Penaeus setiferus) were higher during 1976 than during subsequent years,

               and blue crab numbers were generally higher in 1975 and 1976 than in

               1977-78, which was consistent with the changes in salinity of the period

               and the possible effects of diversion of fresh water by the construction of

               the two-mile channel in 1976.

               3. Sike's Cut (stations IA and 1B)

                    Physic al, chemical, and biological factors at station IA (Figures

               31-35) and station 1B (Figures 36-40) indicate no observable, short-term

               changes at either station that could be associated with dredging at station

               1B. Numbers of spot and anchovies were generally higher in the vicinity of

               West Pass during 1978. At Sike's Cut, no short-term effects of dredging

               were obvious in terms of physical.' chemical, or biological factors.

               Turbidity was higher during 1978 after dredging, but this trend was not

               apparent in 1976. Salinity at depth was generally lower in 1978, which

               could have been associated with increased numbers of fishes (notably spot)

               at this time. Penaeid shrimp were most numerous at Sike's Cut during 1978.

                    Overall, no short-term (measured over several months) effects of

               dredging and spoiling on water quality and biological response (as measured

               by epibenthic fishes and invertebrates) in the Apalachicola estuary were

               noticeable within the context of the existing sampling regime for 1975

               through 1978 (the last year of dredging in the Apalachicola Bay system).

                                                     29

                 Such observations do not preclude an impact of a shorter duration (measured

                 over days or weeks), although such an impact, if it exists, is probably

                 negligible in terms of an immediate response of the system as a whole.

                 Wind and storm effects on turbidity and color are noticeable on a scale of

                 days. Such effects are short-lived and cannot be noticed within weeks or

                 months of the event. Such observations, within the scope of our sampling

                 effort, would indicate that, in the highly (seasonally) turbid and colored

                 Apalachicola estuary, the impact of dredging on water quality and epi-

                 benthic organisms is not observable in terms of "short-term" (weeks to

                 months) response relative to natural changes in the system such as storms.

                 E. Im pact of Dredging: Sike's Cut

                 1. Habitat Features

                      The long-term physical/chemical data for the four outer bay stations

                 (1A, 1B, 1C, 1X) were analyzed to determine the effect of the cessation of

                 dredging at Sike's Cut in June 1978. The a priori hypothesis was that the

                 surface and bottom salinities at station 18 were stratified when dredging

                 occurred but became mixed as the channel filled in. To test this hypothe-

                 sis, an analysis of variance was designed with a factor for surface/bottom

                 and a factor for during/after dredging. Since the data were taken over a

                 period of time, the residuals violate the independence assumption of ANOVA

                 (i.e., they would be serially correlated). To remove this time dependency,

                 a factor was entered in the table for month number as was a factor for year

                 nested within during/after dredging (nested because a given year does not

                 occur both during and after dredging). In order to have as balanced a

                 design as possible, an equal number of data points for both during and

                 after dredging were used.

                                                   30

                        Stations 1A, 1B, 1C         7/73 - 6/83

                        Station 1X                  7/74 - 6/82

               The ANOVA results are summarized in Table 16. The top/bottom by

               during/after interaction for salinity at station 1B had a p-value of .0039.

               This interaction means that the surface and bottom acted differently after

               dredging than they did during dredging. The same interaction for station

               1A had a p-value of .2677 and for station IX a p-value of .4376. The scat-

               terplot of salinity at station 1B showed that the top and bottom salinities

               came closer together after June 1978.

               2. Salinity Changes and Biological Response

               a. Comparison with Other Estuarine Stations

                    Livingston (1979a) compared the salinity regime and epibenthic biota

               (fishes, invertebrates) at Sike's Cut (station IB) with other areas of the

               Apalachicola Bay system. A comparison with historic salinity levels in the

               region (Table 17) before and after the opening of Sike's Cut indicates that

               areas of the estuary contiguous with the new pass had higher salinities

               after the channel was dredged open. The salinity at Sike's Cut during the

               years of dredging was relatively high and more stable than that in other

               portions of the estuary (Figure 41). The Sike's Cut region during the

               period of maintenance was also associated with high levels of species rich-

               ness and diversity of fishes (Figure 42) and invertebrates (Figure 43)

               relative to other regions of the bay system. Sike's Cut was characterized

               by low dominance and low numerical abundance (per unit sampling effort)

               compared to other areas of lower and more unstable conditions of salinity.

               Nurserying species such as blue crabs and penaeid shrimp were low in num-

               bers, and the nursery function of the low salinity waters was impaired by

                                                    31

                the increased salinity as water from the open Gulf of Mexico was introduced

                into Apalachicola Bay. The continued high salinity was inversely propor-

                tional to the nursery potential and productivity of the estuarine fishery.

                High species richness and diversity was not necessarily viewed as desirable

                within the context of the impaired fishery potential of the Apalachicola

                Bay system.

                    The exact area of Apalachicola Bay affected by Sike's Cut was con-

                sidered to be relatively small according to Mehta and Zeh (1981). While

                Livingston (1979a) showed a biological impact due to the higher salinity,

                the areal extent of such increases remains relatively undetermined in terms

                of empirical evidence. A salinity survey (detailed surface and bottom

                salinities during a flooding tide along 7 transects drawn through Sike's

                Cut; Livingston, unpublished data) was made just prior to the dredging of

                the Cut in 1984. The preliminary results indicate that the area affected

                by high bottom salinities from Sike's Cut was greater than that predicted

                by Mehta and Zeh (1980). Another survey is planned to analyze such sali-

                nity changes after the Cut is dredged. These surveys should be able to

                estimate the area of the bay affected by the dredging operations around

                Sike's Cut.

                b. Temporal Changes

                     Bottom and surface salinity (Figure 44) at West Pass (station 1A)

                tended to decrease from 1972 to 1980, after which time there was a general

                increase from 1980 to 1981 followed by a leveling off of salinity. The

                pattern at station IB was different. Surface and bottom salinities did not

                follow the same pattern at Sike's Cut. Bottom salinity was uniformly high

                from 1972 to 1977, after which time the salinity remained uniformly lower

                through 1983. Surface salinity, within high seasonal variability, tended

                to decrease from 1972 through 1977, after which there was a general increase

                peaking in 1980-81. Such patterns tended to follow that observed at West

                Pass. Following the stratification noted from 1972-1977, surface and bottom

                salinities came together largely because of the simultaneously lowered bottom

                salinities and increased surface salinities. While there are too few good

                data to evaluate the actual sill depth at Sike's Cut over this period, the

                dredging events appear to be related to the bottom salinity regime.

                     Dredging occurred with regularity from 1972 through 1976. The preci-

                pitous drop in bottom salinity coincided with the period of no dredging

                from March, 1976, to June, 1978, which would indicate a decrease of sill

                depth at this time. Bottom salinities went up at station 1B following the

                dredging of 1978 at the same time that bottom salinities at West Pass were

                still decreasing. After the 1978 dredging event, bottom salinities

                followed a bay-wide cycle of moderate increases, but the consistently high

                salinities never returned over the period from 1978 to 1983. This result

                would indicate a rapid filling of the sill depth at Sike's Cut and a reduc-

                tion in the amount of high-salinity water from 1977 to the present time.

                Thus, a combination of natural long-term salinity cycles and the pattern of

                dredging at Sike's Cut appear to have defined the general level of bottom

                salinity in this region of Apalachicola Bay.

                     The primary question is whether or not a general decrease in salinity,

                from about 30 ppt to somewhere between 20 and 25 ppt, would have an effect

                on the epibenthic fishes and invertebrates taken at, Sike's Cut. If so,

                there would be a break in the faunal distributions at some time between

                1977 and 1978. A related question (see above) concerning the areal extent

                                                    33

                of 'such impact is also of importance to a comprehensive review of the

                Sike's Cut issue.

                     A,complete community analysis was made of epibenthic fishes and inver-

                tebrates taken at each of the permanent stations in the Apalachicola

                estuary from 1972 through 1983.  For the sake of simplification, the major

                comparison was made between the dredged outer station 1B (Sike's Cut) and

                the undredged outer station 1A (West Pass), although other stations were

                included where necessary. The comparison of the natural (West) pass with

                the man-made Sike's Cut is not entirely satisfactory. It should be noted

                that such a comparison is not meant to be a decisive test of the hypothesis

                that Sike's Cut has affected the productivity of the Apalahcicola Say.

                However, a review of both passes, in a comparative sense, allows the possi-

                bility of determining biological response along natural gradients of

                salinity and the changes at West Pass (and other areas of the bay) relative

                to temporal variability of river flow and local rainfall. Gradient analy-

                sis (along sets of permanent stations in the estuary) thus represents a

                first-cut evaluation of the biological response of spatial/temporal habitat

                factors such as salinity.

                     Analyses of the total numbers of fishes in the Apalachicola estuary

                (Figure 45) show that fish abundance increased at station 1 after 1976-77

                whereas the major abundance at station 2 occurred from 1975-1977, 1981, and

                1982. Fish abundance was substantially lower at stations 1A and 1B. Fish

                abundance was highest at West Pass during 1978, a period of relatively low

                overall salinity. Peaks of high numbers of fishes at station 1B occurred

                during periods of low salinity in 1978 and 1981. There was a generally

                inverse relationship between numbers of fishes and salinity. These

                                                    34

                patterns of generally higher numbers of fishes at station 1B subsequent to

                1977-78 were due largely to the population fluctuations of the spot

                (Leiostomus xanthurus), a euryhaline estuarine species (Figure 46).

                     The trends of species richness (total number of fish species) and fish

                species diversity at stations 1A and IB from 1972 through 1983 are given in

                Figure 47. Fish species richness and diversity peaked at West Pass during

                1976-1977. There was a generally increasing trend following the low levels

                during 1978-1979 (period of reduced salinity). At  Sike's Cut, the trend

                was downward for both indices over the study period, which was generally in

                synchrony with the reduced bottom salinity in the area after 1978.

                     Analysis of numerical invertebrate abundance (Figure 48) indicates a

                decline at station 2 after 1976. The generally low numbers of epibenthic

                invertebrates at stations 1A and 13 (Figure 48) make it difficult to see

                any particular trend in the data over time. However, euryhaline species

                such as the white shrimp declined at station 2 (Figure 49) after 1976,

                whereas blue crabs (Figure 50) increased at station 1 and declined at

                station 2 subsequent to 1976. Blue crab numbers were uniformly low at

                stations 1A and 1B over the study period. Animals that indicate higher

                salinity such as pink shrimp (Penaeus duorarum) (Figure 51) declined at

                station I after 1976, while they tended to increase at station 2 after

                1977. Pink shrimp were in lower abundance at Sike's Cut after 1975.

                Another species that prefers higher salinities, the brief squid

                (Loliguncula brevis) (Figure 52), showed similar declines at Sike's Cut

                                                                           0
                after 1976. These distributions are consonant with the long-term salinity

                observations as indicated above, and indicate a biological response to the

                opening of the two-mile extension.

                                                    35

                     Long-term trends of species richness and diversity at West Pass and

                Sike's Cut (Figure 53) indicate patterns similar to those observed for

                fishes. Both indices followed general salinity trends with periodic

                increases at West Pass and a more or less steady decline at Sike's Cut over

                the study period.

                     An integration of changes in the fish communities at West Pass and

                Sike's Cut is given in Figure 43. At West Pass, periods of low salinity

                (1972-73, 1974-75) (1977-79, 1981-82) were grouped together. Overall, the

                various annual groupings were mixed according to trends observed above. At

                station 1B, however, there were 3 main groupings: the high-salinity years

                (1972-1976) were associated; subsequent to 1976, two primary groupings were

                observed, which tended to follow the periods of low bottom salinity (1979-80,

                1981-82) (1976-79, 1980-81). This analysis is further evidence that the

                observed shift in bottom salinities at Sike's Cut between 1977 and 1978 had

                an effect on the biological organization in this area.

                     As part of the process of reduction of variables, correlation matrices

                were run for the chief fish and invertebrate indices for all stations over

                the entire study period (1972-1983, Table 18). Relatively high correlations

                were noted for fish Hurlbert diversity and Brillouin evenness, fish Hurlbert

                diversity and Brillouin diversity, invertebrate Hurlbert diversity and

                Brillouin evenness, invertebrate number of species and Brillouin diversity,

                invertebrate Briollouin diversity and Hurlbert diversity, and invertebrate

                Brillouin diversity and Brillouin evenness. Factors were reduced accor-

                dingly (where necessary) for subsequent statistical analyses. The fish

                correlations indicate that numbers of individuals and species richness were

                possitively correlated. Likewise, species richness and the various

                                                    36

                diversity indices were correlated. Similar patterns of correlation were

                noted among the invertebrate indices although some correlation existed here

                between the log of numbers of individuals nad Brillouin diversity. A study

                of these indices allows some understanding concerning the community struc-

                ture of estuarine organisms in the Apalachicola Bay system. In general,

                high dominance is generally associated with low species diversity and

                evenness.

                     An analysis of variance for various epibenthic fish and invertebrate

                indices at stations 1A and 1B was carried out comparing those years before

                (1975-77) and after (1979-81) the cessation of dredging at Sike's Cut

                (Table 19). A graphical representation is given for this analysis (Figure

                54), which used only 6 years of data for the balanced statistical (ANOVA)

                model. The general increase in numbers of fishes at station 1B after 1978

                is evident. Fish species richness and diversity declined at both stations

                during the period 1979-81 relative to the figures during 1975-77, with the

                most precipitous declines evident at Sike's Cut during 1981. Such trends

                were consistent with the general increase in the numbers of spot

                (Leiostomus.xanthurus taken at Sike's Cut during this period. Croaker

                were generally more abundant at West Pass. The invertebrate data (Figure

                34) were somewhat different, with numbers of individuals and species higher

                at station 1B and a general decline of richness and diversity indices at

                both stations over the study period. White shrimp and blue crabs, however,

                were higher at station 1A than at 1B before the cessation of dredging in

                1978; after 1978, these station positions were reversed, which is consis-

                tent with the observed, long-term salinity regimes. The statistical

                results (Table 19) indicate that there was a significant (p < 0.05)

                                                    37

                difference between stations 1A and 1B in terms of invertebrate (log)

                numerical abundance, invertebrate number of species, and invertebrate spe-

                cies diversity (Brillouin, Hurlbert). There was a significant difference

                between two or more months of the year for fish numerical abundance, fish

                numbers of species, and fish Brillouin diversity. There was a significant

                difference between the before-dredging and after-dredging means for fish

                number of species (averaged over stations).

                F. Impact of Dredging: The Two-Mile Extension

                     1. Habitat Features

                     A factorial design ANOVA was run with factors for year, top or bottom,

                and month. If there was a change in the surface/bottom relationship, we

                would expect a significant surface/bottom by before/after dredging interac-

                tion. There were not equal data sets before and after dredging, so a term

                for it was not included in the ANOVA. A second ANOVA was run with factors

                for before/after, surface/bottom and month. The results of the two ANOVA's

                were combined to calculate the surface/bottom by before/after interaction.

                The first such ANOVA results provided a year by surface/bottom interaction
                sum of squares(A). The second ANOVA provided the before/after by surface/
                bottom interaction sum of squares(B) which was treated as a 1 degree of

                freedom contrast. By subtracting (B) from (A) we calculated the correct

                error sum of squares for testing the contrast (p-values summarized in table

                20).

                     None of the interactions were statistically significant. The only

                significant effect was at station 3 where the mean salinity before dredging

                was different than that after dredging; however, there were only 2 years of

                                                    38

                data at that station before dredging with 7 years after. It is not

                possible to say that this difference was caused by dredging.

                     In summary, this analysis showed no differences in habitat features at

                the subject stations due to the opening of the two-mile extension.

                G. Impact of Dredging    The Intracoastal Waterway

                     1. Water Quality, Sediment Quality and Infauna

                     In a recent regional analysis of pollution sources in the Apalachicola

                River-Bay system (Livingston, 1983b), specific stations were located in the

                Intracoastal Waterway (Figure 1, Table 3). These included stations 2, A7,

                and 1C. Water quality and biological (benthic infaunal macroinvertebrates)

                analyses (Table 21) in these areas indicated that the Intracoastal Waterway

                at the mouth of the Apalachicola River (station 2) was not polluted with

                organic matter, heavy metals, or other forms of pollution, although it was

                biologically stressed (low species richness, diversity, evenness), possibly

                as a result of natural conditions.

                     Farther out in the bay (stations A7, 1C), despite high concentrations of

                organic matter and silty conditions, the water and sediment quality and

                biological indices were close to background conditions. This observation

                is qualified by relatively high sediment burdens of lead, cadmium, and

                chromium (Livingston, 1983a). However, the biological community was rela-

                tively productive and high in species richness and diversity. This survey

                was conducted approximately 51/2 years after cessation of dredging in the

                Intracoastal Waterway of Apalachicola Bay.

                     This analysis indicates that, while the Intracoastal Waterway is con-

                taminated with heavy metals in certain areas (Livingston, 1983a) (possibly

                as a result of the increased boat traffic and concentration of silt

                                                    39

                fractions of the sediments with associated metal burdens), the biological

                organization of the benthic infaunal macroinvertebrates at various stations

                (distant from urban runoff) was not adversely affected by previous dredging

                activities. The fact that such studies were carried out more than 5 years

                after cessation of dredging would qualify the above results. However,

                these data tend to confirm the results of other studies in the region

                (Water and Air Research, 1975; Taylor, 1978).

                     1. Water Quality, Sediment Quality, and Infauna

                     No long-term data were taken in the vicinity of the East Point Chan-

                nel. However, a short-term analysis was made of the proposed dredging and

                construction associated with the East Point Breakwater (Livingston, 1983a).

                A synopsis of the findings of this study is given in Appendix A. The

                dredged channel was polluted with heavy metals, oils and greases because of

                runoff from East Point. Channel sediments were higher in the silt/clay

                fractions than other stations in the area, and such sediments were also

                high in nutrients. The channel areas were characterized by high Biochem-

                ical Oxygen Demand and seasonally low dissolved oxygen. Such conditions

                were associated with depauperate faunal (i.e. benthic infaunal macroinver-

                tebrate) assemblages. The dredged areas along the East Point Channel were

                biologically stressed by a combination of dredging, urban runoff, and local

                boat traffic.

                     The dredged channels were viewed as repositories for fine sediments

                along with attached pollutants (oils and greases, metals) and organic

                material (high B.O.D., low dissolved oxygen). These observations were con-

                sistent with regional analyses of the distribution of pollutants and the

                                                    40

                biological organization of the Apalachicola River-Bay system (Livingston,

                1983b). Such effects were dependent on two major factors: the dredged

                channel and the presence of urban runoff in the immediate vicinity. Thus,

                areas such as the St. George Island (Sike's Cut) dredge site were relati-

                vely free of pollution, while areas such as the two-mile channel and East

                Point Channel were polluted (Appendix A).

                I. Comparison of Results to Other Findings

                     Most of the previous studies of the impact of dredging and associated

                activities on the Apalachicola Bay sytem (Ingle, 1952; Water and Air

                Research, 1975; Taylor, 1978) have concentrated on localized, short-term

                effects on a relatively limited set of physical and biological variables.

                The benthic macroinvertebrates have been used as indicators (and rightly

                so) as such organisms reflect specific forms of environmental influence.

                However, such organisms, when located in the Apalachicola estuary, repre-

                sent a relatively adaptable group of species that often have relatively

                short life histories and high levels of recruitment. The possibility of

                long-term changes in the system (due to accumulation of contaminated sedi-

                ments from urban runoff and altered current patterns and salinity

                distributions) have been largely ignored. The results of this survey indi-

                cate that dredging activities have affected various portions of the system

                because of the above-mentioned, long-term processes. Altered current and

                salinity structure of the estuary are partaicularly important in the deter-

                mination of the distribution of species that form the basis of important

                sport and commercial fisheries in the region. Although such changes may be

                either detrimental or fortuitous, depending on the action and the point of

                view of different sets of users of the estuarine productivity, more care

                                                    41

                should be taken in the analysis of effects before the dredging is under-

                taken. For instance, spring and summer dredging in the intracoastal

                waterway can have adverse impacts on developing forms of penaeid shrimp and

                oth er species that use the estuary as a nursery (see Livingston, 1983,

                1983c, for details of the spatial/temporal distribution of such species).

                In this way, serious mistakes can be avoided, and the dredging activities

                can be undertaken in a way that has minimal negative impacts on the bay

                sytem as a whole.

                     The results of this review indicate that dredging activities in the

                Apalachicola estuary can have effects on the physical, chemical, and biolo-

                gical structure of the system, but that such effects cannot be easily

                predicted a priori   More empirical work is needed if the productivity of

                the system is to be maintained and preserved in the future.

                                Professor, Department of Biological Science

                                         Florida State University

                                        Tallahassee, Florida 32306

                                Summary of Conclusions and Recommendations

                 1. Because of  the need (for funding purposes) for the breakwater project

                     and the channel dredging project to be issued and evaluated as

                     separate projects (U. S. Army Corps of Engineersp Mobile District),

                     there was some confusion concerning whether or not the environmental

                     impact analysis should be considered as one project. While it is true

                     that the breakwater project does not depend on maintenance dredgiusp

                     if the breakwater is established, such dredging will be needed and may

                     be changed because of altered sedimentation rates and spoiling proce-

                     dures and effects. Consequently, there is a functional association

                     between the two projects and this evaluation was carried out under the

                     assumption that the two projects are interrelated from the standpoint

                     of environmental response.

                 2.  No hard scientific data were available regarding the rate of sedimen-

                     tation that would occur behind the breakwater; hencep while the

                     estimates of the U. S. Army Corps of Engineers (i.e., 509000 cubic

                     yards at 18-month intervals) were used for this review, such figures

                     are tentative. The last time maintenance dredging was carried out in

                     the East Point channel was 1978.

                 3.  Construction of the breakwater and open water spoiling associated with

                     the dredging of the East Point Channel will eliminate the immediate

                     benthic (bottom) communities in areas of rock and spoil placement.

                     Such effects will be mitigated to a certain (undetermined) degree by

                     increased habitat diversity associated with the rock substrate and

                     projected rapid recolonization of the spoil banks by organisms that

                     are adapted to the natural variability of the highly turbid estuary.

                     The relatively short life cycles of various benthic organisms in this

                     area will add to the speed of recovery.

                4. The construction of the breakwater should have negligible effects  on

                     the current structure and tidal circulation of St. George Sound and

                     the salinity structure of the Apalachicola estuary.

                     Construction of the breakwater (rock placement and small-scale

                     spoiling) will have temporary, though negligiblev effects on water

                     quality in the area. Such effects include short-term increases in

                     turbidity and sedimentation in the immediate vicinity. Such construc-
                     tion will probably exace*rbate, to some degree-V seasonal reductions of

                     water quality (i.e., dissolved oxygen). However, such effects will be

                     slight compared to the existing poor water quality conditions due to

                     urban runoff (point and uon-point sources) from East Point, heavy boat

                     usep and previous dredging and spoiling effects.

                6.   The dredging and spoiling activities associated with the East Point

                     Channel maintenance should have a negligible influence on the current

                     structure-and salinity regime of the estuary.

                7.   The dredged channel should act as a sink for nutrients and other

                     pollutants from urban runoff from East Point and boat traffic in the

                     area. Because of organic loading, the Biochemical Oxygen Demand in

                     the channel, will probably be increased. Analyses in the East

                     Point and Two-Mile channels show high concentrations of nutrients

                     (nitrogen and phosphorus compounds), oils and greases, and toxic

                     metals. Such substances are probably associated with the finer (i.e.,

                     silt) fractions of the sediments.

                  8. Elutriate tests that mimic   the open water spoiling of dredged sedi-

                      ments indicate that such spoiling will probably cause temporary

                      increases in nutrient levels in the water. Elutriate studies at

                      various dredged sites in the Apalachicola estuary also indicate    that

                      under conditions 'similar to open-water spoiling, the metal contami-

                      uants will remain, prima ilyp with the sediments. Since iron is

                      naturally high in estuaries and is known to have minimal toxic impact

                      on estuarine biota, this metal should not be a cause of concern. The

                      elutriate datat while not entirely conclusivey would indicate that water

                      quality deterioration due to the release of metals at the spoil sites

                      will be minimal. There is a possibility that sediment movement away     from

                      the spoil banks could lead to some movement of metals into local areas.

                      ment composition, and benthic macroinvertebrates in St. George Sound

                      (off East Point) were analyzed to determine existing environmental

                      conditions in the study area. A direct relationship was noted between

                      the degree of urban development, boat traffic and dredging activities,

                      and the deterioration of the biological structure of associated bay

                      areas. Such human activities were associated with the postulated

                      destruction of near-shore grassbeds and the deterioration of the

                      benthic macroinvertebrate community . There was a direct correlation

                      of sediment quality (i.e. siltationg high nutrients, oils/grease, and

                      metals) and adverse biological impact. Biotic recovery was noted in

                      areas associated with the construction area of the proposed breakwater

                      and spoil sites.

                10. Dredged areas proximate to areas of urban runoff act as a sediment

                     trap for silt, which is often associated with pollutants such as

                     nutrientsp oils and greases, and metals. Such areas are largely

                     devoid of macrobenthic organisms. Dredging and open water spoiling

                     associated with the East Point project will have (smothering) effects

                     at the immediate spoil sites and temporary increases of nutrients in

                     the surrounding waters. Because of the existing deteriorated state of

                     inshore areas of St. George Sound off East Point and the fact that

                     there are no grassbeds or oyster bars in the immediate vicinity,

                     adverse biological effects due to the combined projects should be

                     minimal in areas inshore (north) of the breakwater. Adverse effects

                     south of the breakwater should be largely confined to the local areas

                     and should be subject to some form of recovery.

                11.  The determination of whether or not these projects should be carried

                     out depends on a balan ced judgement of potential environmental impact

                     versus community needs. It has been rightly pointed out that the

                     Apalachicola estuary is a special area: Class II waters, an Aquatic

                     Preserve and Special Waters, Outstanding Florida Waters, and a

                     National Estuarine Sanctuary. For this reason, all dredging and

                     spoiling in the area should be carefully evaluated. Upland spoiling,

                     in environmentally appropriate areas, should be considered as a more

                     preferable alternative to open-water spoiling. On the other side is

                     the real need of protection that will be afforded a community that

                     represents more than 1/3 of Florida's oyster industry. This need is a

                     historic one, and the issue should be resolved immediately.

                 12. Based on the above considerations, I would recommend that a variance

                      be issued by the Florida Department of Environmental Regulation so

                      that the East Point Breakwater can be constructed along with main-

                      tenance of the East Point Channel* As part of this project, I would

                      recommend the following stipulations:

                      A. The search for an upland spoil site should be continued. Such an

                          option remains preferable to open-water spoiling.

                      B.  The Army Corps of Engineers (Mobile District), the Florida

                          Department of Environmental Regulation, and the Franklin County

                          Commission should initiate a program of study to evaluate the

                          environmental effects of the East Point projectse   Such a study

                          could be carried out within the auspices of the Apalachicola River

                          and Bay Estuarine Sanctuary,. Such a s-tudy would be most valuable

                          in the evaluation of such dredging and spoiling activities

                          throughout the bay system. In addition, should any adverse

                          effects be noted, it would provide a stronger case for the upland

                          spoil option.

                      C.  All construction activities, including the maintenance dredging

                          and spoiling, should be carried out during winter-early spring

                          months of naturally high turbidity, sedimentationg and dissolved

                          oxygen,

                      The above re commendations would thus allow the development of a needed

                 facility for the people of East Point while minimizing the environmental

                 impact and providing needed information for possible improvement of

                 dredging activities in the estuary.

                 1. Review of Existing Data

                 A. proposed Breakwater and Dredging operations

                     A detailed description of the proposed breakwater project is given in

                 the revised Draft Environmental Impact Statement (U. S. Army Corps of

                 Engineersp Mobile District; 1982) with further revisions as outlined in

                 Appendix III. Briefly, the plan is to provide a sheltered harbor approxi-

                 mately 500 ft offshore and parallel to East Point, Florida (Figure 1). This

                 is to be accomplished by construction of a breakwater (Figure 2). The pro-

                 posed structure would require the placement of about 18,500 cubic yards of

                 bedding material and about 8,300 cubic yards of well graded cover stone in

                 St. George Sound. Approximately 129000 cubic yards of sandy material

                 dredged from the breakwater area would be placed south of the alignment.

                 No flotation channel would be necessary (this concession was made by the

                 U. S. Army Corps of Engineers to a request by the Florida Department of

                 Environmental Regulation). The proposed action would also require main-

                 tenance dredging of approximately 5OpOOO cubic yards from the channel

                 behind the proposed breakwater (Appendix III). It is estimated that such

                 dredging would occur once every 18 months and spoils would be moved by a

                 'hydraulic pipeline and placed into open water sites adjacent to the channel

                 (Figure 3). The disposal sites would be elevated above mean low water. An

                 alternative plan is to use an upland disposal site (U. S. Army Corps of

                 Engineers, 1982; Appendix 1Iy Appendix III) for the dredge spoils from the

                 East Point Channel. While it has been "noted that the plan for the break-

                 water is not dependent upon maintenance dredging" (Appendix III), the

                 obverse is probably true since maintenance dredging could be altered by the

                 contruction of a breakwater. Further, the exact amount of spoil and timing

                                                    2

                of the dredging operation remain unclear without exact data concerning

                sedimentation rates behind the breakwater. While these two projects have

                been separately presented, sedimentation rates (hence the necessity to

                dredge) and spoiling procedures (should the open water spoiling option  be

                taken) would be dependent in various ways on the breakwater. This depen-

                deuce would mean that, in a functional sense, the breakwater and proposed

                channel dredging should be evaluated as a functional unit for any environ-

                mental evaluation.

                     According to conversations with personnel from the U.  S. Army Corps of

                Engineers (Dru Barrineau, Doug Nestor, Mobile; personal communication,

                1983), the breakwater operation and maintenance dredging come from two  dif-

                ferent authorities; the breakwater is a new project while the dredging  is

                part of an existing program. The East Point Channel was last dredged in

                1978. Funding is thus  from different sources and under different authori-

                ties for the two projects. The Florida Department of Environmental

                Regulation has chosen to tie the two projects together in terms of  a water

                quality evaluation so that neither project, can be certified without the

                other. According to the DER (J. Craft; personal communication, 1983), the

                breakwater and spoiling from the dredged channel will both cause direct

                habitat destruction (which cannot be denied since subsrate will be lost as

                a result of such actions). Also, both actions will also cause degeneration

                of the water quality (J. Craft; personal communication, 1983); according to

                this line of reasoningt water quality will be affected behind the break-

                water (the marginal to bad water quality will be exacerbated by the

                breakwater) and in front of the breakwater as a direct effect of spoiling.

                The Army Corps of Engineers disagrees with this evaluation and consequently

                                                    3

                has no problem with either action (Dru Barrineau, Doug Nestor, personal

                communication; U. S..A. C. 0. E.9 1982).

                     Because of the confusing state of affairs generated by the differing

                points of view of the Corps and the DER, both aspects of the problem will

                be treated both separately and as a whole or uniform action in terms of

                evaluation of potential environmental effects. The environmental questions

                cannot be so easily separated because the impact of one project (dredging)

                depends on that of the other (the formation of the breakwater). Overally

                the enviror,=ental assessment will thus address both issues as they relate

                to possible habitat destruction and water quality changes in the

                Apalachicola system.

                B. Potential Phvsical/Chemical.Impacts

                1. Breakwater

                     Several factors should be considered in the construction of the break-

                water. These include modifications to existing current and salinity con-

                ditions and changes in habitat and water quality.

                     a. Modification of current and salinity structure of the bay

                     According to the Raney (2-dimensional) model (U. S. A. C. 0. E.,

                1982), which is based on a breakwater approximately 500' from shore, the

                breakwater should have a negligible effect on the overall tidal circulation

                in Apalachicola Bay. Any effects will probably be confined to the local

                area as delineated by a 2-mile radius from the East Point shoreline.

                According to model projectionsy the breakwater should produce a slight

                channelling effect with minor elevations of current velocities behind the

                breakwater. There is some controversy on this point, but the significance

                of this action on circulation remains minimal.

                                                    4

                     b. Modification of water quality behind the breakwattr-

                     There is some reason to consider that the construction of the break-

                water will increase sedimentation behind the breakwater although there is

                no universal agreement on this issue (U. S. A. C. 0. E., 1982; J. Craft,

                Florida Department of Envi ronmental Regulation, personal communication).

                The likelihood is that water quality conditions (such as the dissolved oxy-

                gen and turbidity) of the water behind the breakwater will undergo a slight

                deterioration. This change would mean lower dissolved oxygen and higher

                turbidity* Such impacts would have to be evaluated within the context of

                the area in question (i*e*, there are already serious water quality

                problems in the area because of previous dredin.g and storm water runoff

                from East Point; see below). In this contexty it is doubtful that there

                would be a significant alteration of water quality behind the breakwater.

                     c. Direct effects of rock Rlacement

                     There is no doubt that the benthic (bottom) habitat will be destroyed

                by placement of the bedding material and stone on the sediments. Attendant

                water quality effects will probably result in localp temporary increases in

                turbidity and sedimentation. Such impacts will be minimal in terms of the

                overall turbidity levels of the area involvedg if this action is carried

                out during winter-spring periods of high natural turbidity, sedimentation

                and dissolved oxygen. Dredging directly associated with the breakwater

                (about 12,000 cubic yards of sandy material) will have direct adverse

                effects on the benthic habitat in areas of dredging and spoiling. Such

                effects should be relatively transitory considering the limited nature of

                the dredging operation and the types of spoil being placed in the area.

                                                    5

                     In st-aryt the environmental impact of the placement of the break-

                water will probably be confined to areas immediately affected by the

                deposition of rock and spoil associated with the project. Such loss    of

                babitat shold be mitigated to a certain degree by new habitat or substrate

                provided by the breakwater itself and the relatively rapid colonization of

                spoil banks by organisms adapted to the high turbidity and sedimentation of

                the estuary, as long as the project is carried out during a winter-early

                spring period.

                2. Dredging Operations Within the East  Point Channel

                     Considerations of the dredging operations behind  the breakwater and

                spoiling south of the breakwater are complicated by the lack of certainty
                concerning the magnitude and frequency of such 'operations (see above) and

                the relatively low quality of the spoils (see below). Because of the lack

                of more exact data, I will use the projected levels for this evaluation

                (i.e.9 509000 cubic yards of spoil taken from behind the breakwater and

                deposited south of the breakwater once every 18 months; U. S. A. Ce E.9

                1982; Appendix III

                     a. Modifications of current and salinity structure of the ba
                                                                                 Day

                     While I can find no direct information on this point relating to

                effects of dredging and spoiling operations per se, it is probable that the

                above treatment of the breakwater (section I-B-1-a) would apply to this

                situation (i.e., minimal impact on current patterns and salinity structure

                of the bay).

                     b. Modification of water auality

                     it is in this area that most of the potential problems (audp

                correspondinglyg most of the controversy) exist for the proposed project

                                                                                        . . .... ... .

                                                      6

                 (see letter from J. Craft, Appendix II). A detailed response to this issue

                 is thus appropriate.

                      1. Sources of pollution and organic enrichment

                      sources of pollution in the East Point area are  varied. There is

                 point and non-point pollution from urban runoff from  East Point... Heavy

                 boat traffic will contribute organic material and metals.. Dredging activi-

                 ties will cause the concentration of fine sediments (clay/silt f:ractions)

                 in the dredged channels. Estimates of organic loading Eas determined by

                 Biochemical Oxygen Demand (B.O.D.) in mg/l; U. S. A. C. E., 1982] from the
                 18 oyster processing plants approximate 2,361 gallons per' day, 50% of which

                 enters St. George Sound. This figure is considered to be a maxim= since

                 there is considerable daily and seasonal variab ility in the oyster packing

                 and processing industry. Since estimates of non-point B.O.D. waste loads

                 are unavailable, the high point of the estimated range of 2 mg/l   to 2,070

                 mg/l was used to calculate maximum dissolved oxygen deficits foi;  the area.

                 This is reasonable but is probably on the low side during specific periods

                 of high temperature, heavy rainfallo and lateral runoff from the East Point

                 area into the sound. The waste assimilative capacity for the existing

                 navigation channel for various offshore breakwater alignments was calcu-

                 lated according to these estimates. The projected dissolved oxygen (D.O.)

                 deficits ranged from 0.0 (minimun point source B.O.D. loadings) to 3.1 mg/l
                 Emaximum combined (point and non-point) source B.O.D. loadings for plan 3].

                 The D.O. deficit for the modified plan 5 (recommended) was 1.5 mg/l.

                 According to a letter from Ms. V. Tachinkel, Secretary of the Florida

                 Department of Environmental Regulationg elimination of the direct discharge

                 Of Washdown from seafood processing houses would be one condition for

                                                    7

                permitting. Such modification would partially alleviate the loading rates*

                from East Point into St. George Sound.

                     in any case, during summer periods of high temperature and local

                rainfall (and urban runoff), the dissolved oxygen levels at depth in the

                channel will probably be low.

                     2. Sed iment quality: a comparison

                     The chief concernp in terms of permitting, is the water quality

                question relating to dredging in the East Point channel and spoiling   south

                of the breakwater. As noted above, while this project is not part of the

                breakwater project per se, and while the breakwater is not directly depen-

                dent on maintenance dredging, the two actions are functionally associated,

                so the water quality issue concerning dredging activities will have an

                important bearing on the breakwater issue. Data concerning the quality of

                sediments in these areas are given in Table 1. Sediment quality in the St.

                George Island Channel is relatively good. Most of the sediments here fall

                within the range of fine to coarse grained sand. Within the two-mile chan-

                nel area, oils and greases are higher, especially at sites GI 2 (Gulf

                Intracoastal Waterway disposal area) and TM3 (Two-Mile extension

                channel). Sediments within these channels are enriched in nutrients and

                metals such as copper (Cu), iron (Fe), lead (Pb), and Zinc Qn). Sediments

                at TM2 and TM3 are higher in the silt/clay fractions than stations TM41 TM5

                and GI 2, which are mainly characterized by fine sand. Sediments from the

                East Point Channel area are also relatively high in oils and greases (EPlt

                EP5), nutrients (EPI, EP20 EP39 EP5), and metals such as copper (EPO, iron

                (EPIt EP3, EPS), lead (EP3, EP5), and zinc (EP1, EP5). Silt/clay fractions

                are relatively high at stations EP1 (inshore, west), EP3 (within the

                                   1b

                                                    8

                dredged channel(, and EP5 (inshore, east). Stations in the spoil banks

                (EpZ, west; EP4y east) are dominated by fine to coarse-grained sands. Such

                a pattern indicates sedimentation within the dredged channels and erosion

                of the spoil disposal areas.

                     As is consistent with most studies on the subject, oils and greases,

                nutrients, and metal contamination were most closely associated with the

                fine-grained sediments (i.e., the silt-clay fractions). The area off East

                point was higher in nutrient enrichment than either of the other study

                areas. Oil/grease and metal contamination was low at the St. George

                Channel site and comparable at the two-mile/Gulf Intracoastal Waterway site

                and the East Point Channel Site.

                     3. Associated water quality questions

                     The environmental assessments by the Florida Department of

                Environmental Regulation (Table 2) point out certain problems with the

                proposed actions. The receiving area is within Class II waters of the

                state of Florida. This area is also an Aquatic Preserve and Special Waters

                ( Section 17-3.041, (2)(f) and (g)), Outstanding Florida Waters (Florida

                Administrative Code), and a National Estuarine Sanctuary (Coastal Zone

                Management Actf P.O. 92-583 with amendments P.O. 94-370). While no scien-

                tific data are given, a qualitative evaluation indicated low water quality

                in the East Pont channel (with attendant poor levels of biota in the

                sediments) but relatively healthy animal populations at the proposed spoil

                disposal sites. The biological impact of dredging in "mucky, anaerobic and

                possibly toxic" sediments of Two-mile, East Point and Scipio Creek would be

                less, according to this evaluationg than in channels further out in the bay
                (11sandy and aerobic"). The impact of placing of the breakwater and

                                                    9

                dredging would be to destroy benthic organisms within the construction

                &real such organisms would possibly repopulate submerged surfaces of the

                breakwater after construction. The DER evalation indicates that the break-

                water may worsen the dissolved oxygen concentration in the existing

                channel; mixing of such water may cause "harm to adjacent waters" according

                to this evaluation. According to the DER assessmentf open water disposal

                of I'mucky" bottoms from such areas would generate turbidity problems

                although organisms of the bay are probably "moderately tolerant of

                turbidity." Upland spoil disposal is recommended (Figure 4).

                     Because of concessions regarding the elimination of the work channel

                and direct discharge from washdown water, the primary question concerning

                the permitting of the East Point Breakwater and dredging and open water

                spoiling of sediments taken from the East Point channel pertains to water

                quality in the dredged channel and spoiling areas. According to an

                undatedv anonymous D.E.R. briefing paper (Appendix IV)l spoil quality is

                low because of high oil/grease levels, -onia-uitrogen, and metal con-

                centrations. Elutriate data (Table 1) indicate violations of water quality

                standards for copper, iron, and lead. Such violations in other parts of

                the bay evidently have been overcome by variances given by D.E.R. (J.

                Craft, personal communication).

                     Judging from such da-ta in the G.I.C.W.W. and the Two-mile Channel

                (Table 1), there is little substantive difference in spoil quality in terms

                of oils and grease and metals between these areas and the East Point

                Channel area. Basic differences exist between the U. S. A. C. E and DER

                regarding water quality and water flow and sedimentation rates in the East

                Point Channel and water quality changes due to open water spoiling. Since

                                                   10

                channel conditions are already poor, the main question centers on water
                quality problems associated with the disposal of dredged channel sediments.

                it includes the main question of whether metals such as copperl iron, and

                lead will disassociate from the sediments and contaminate surrounding

                water, For this questiony we need the elutriate analyses.

                     4. Elutriate analyses

                    The results of the elutriate tests by the U. S. A. C. E. for various

                areas of the bay are given in Table 1. Virtually no water quality effects
                :
                 re shown at the St. George Island site, as might be expected since the

                 ediments are not contaminated to any degree. Tests in the two-mile chan-

                nel show increased ammonia-nitrogen, phosphorusp and iron content in the

                elutriates. Iron is naturally abundant in the estuary and should cause no

                adverse biological effects. The tests show increased ammonia-nitrogen and

                phosphorus levels.in the elutriate; lead levels in the elutriate are
                slightly increased from sediments taken in the western (inshore) and highly

                contaminated portions of the East Point Channel. These data indicate that

                there should be an immediate, short-term or temporary release of nitrogen

                and phosphorus compounds in the spoiling areas but that the metals will

                remain latgely with the sediments. There could be a movement of such

                metals with the sediments because of erosion of the sediments away from the

                original spoil site. Howeverg these data do not support water quality

                degeneration by metals within the spoil sediments.

                11. Biological Evaluation of the East Point Study Site

                    Materials and Methods

                    Water quality and Sediment Composition

                     An analysis was carried out concerning water qualityp sediment com-

                positionp and the benthic macroinvertebrate (infaunal) assemblages in areas

                associated with the proposed projects (Figure 4). Such areas include the

                East Point Channel (1-11 3-1), proposed breakwater and spoil sites (1-2y

                3-2), channel areas (2-1, 2-2f 2-3), offshore areas (1-3, 2-31 3-3; 5-19

                5-29 5-3, 5-4) and a reference transect (outside of the influence of the

                East Point area) 4-11 4-21 4-3). These studies were based ong and coor-

                dinated withq previous studies carried out within the Apalachicola Bay

                system (Livingston 1980, 1983; Livingston et al., 1983).

                     All sampl-es were taken.on 15-16 March, 1983. Surface and bottom water

                samples were taken with a 1-liter Kemmerer bottle. Turbidity was measured
                with a Hach model* 2100-A turbidimeterg and color was determined using an

                American Public Health Association platinum-cobalt standard test.

                Temperature was determined using a stick thermomometer, and salinity was

                measured with a temperature-compensated refractometer. Field measurements

                of dissolved oxygen and pH were made with metering devices. A standard

                Secchi disk was used to determine light penetration. Sediments were taken

                with a corer (diameter 7.62 cm), and analyses were carried out using the

                top 10 cm of each core sample according to processes described by I an
                (1952), Folk (1966), Cummings and Waycheck (1971), and Ingram (1971). This

                analysis included determination of particle size and sediment organic com-

                Position with a computer program developed by J. P. May (Department of

                                                    12

                GeologYt Florida State University). Detailed descriptions of these methods
                are given by Livingston (1978).'

                2. Benthic Macroinvertebrates

                     Benthic macroinvertebrates were sampled with a hand-held corer

                (diameter 7.7 cz) at sediment depths of 15 cm. Ten subsamples were taken

                at each station. Each subsample was washed through a 0.5-an screen.

                organisms were fixed with 10% buffered formalin and rose bengal (200 mg

                1-1). Animals were then transferred to 40% isopropyl alcohol, sorted and

                identified to species and counted. All biological sampling was based on

                previous assessments relative to microhabitat distribution, runoff pat-

                terns, and spatial/ temporal trends of biotic composition (Livingston 1976,

                1978; Livingston et al., 1976a). Sampling effort in all cases was deter-

                mined by analysis of species accumulation using multiple sub-samples

                (Livingston et al., 1976b). Data analysis was carried out with an interac-

                tive computer program under the KRONOS operating system on a Cyber 74

                computer (Florida State University Computing Center). All computations

                were based on numerical abundance and numbers of species. Statistical

                calculations were made using the Statistical Package for the Social

                Sciences. Specific indices and tests for significance have been detailed

                by Livingston (1975, 1978), Livingston and Duncan (1979), and Livingston et

                al. (1978).

                B* Background Information

                     Permanent sampling sites (visited monthly from Marcht 19729 to present

                to Collect data concerning water quality and biological structure) are

                shown in Figure 5. In addition, a complete habitat assessment was made by

                divers and scientists of all inshore waters of the Apalachicola Bay system

                                                        13

                 (from Indian Pass to Alligator Harbor,    Livingston, 1980). The onshore por-
                 tions of the East Point study area are    characterized by 31 oyster housest

                 vhich are concentrated on the eastern portion of the along-shore transect

                 (Figure 4; offshore transects 1-x, 2-x, 3-x). The number of houses goes

                 down as one proceeds from west to east; transect 4-x was established in an

                 area.devoid of upland development (just across from the highway patrol

                 station). Transects 1-x and 3-x were run through the existing channel and

                 proposed spoil sites; transect 2-x ran through the existing channel.

                 Existing grassbeds (Figure 6) are located east of the study area and,

                 together with upland marshes, are almost entirely lacking in the East       Point

                 drainage area. Oyster bar distribution (Figure 7) is lacking in the study

                 area. Field notes concerning the area in question (Table 3; Livingston,

                 1980) providemore details of the general environmental setting, which is

                 characterized by urban runoff, high levels of boat traffic, and disturbance

                 from dredgi ng and filling. Recovery to a more natural setting is apparent

                 from the radio tower (our -station 4-x) eastward.

                      Key climatological, physical, and chemical features of the

                 Apalachicola River and Bay system are given in Figures 8-10. A       general

                 su-n y of physical and biological features (Fig. 11 indicates that,

                 during the March study period,, infaunal macroinvertebrate numbers of indi-

                 viduals are high but declining while numbers of species are moderately

                 high. Long-term changes in benthic macroinvertebrate assemblages in nearby

                 East Bay (Figure 12) are the result of complex interactions (physical, che-
                 micalg biological), which have been worked out for this area. Such 'rela-
                 tionships are simply too involved for a reasonable discussion here
                 (Livingston, 1983). Weekly samples of benthic macroinvertebrates at 2

                                                    14

                 t&tions in East Bay (Table 4) give some indication of background levels

                that may be expected in unpolluted portions of the estuary. Biomass trends
                give a detailed account of seasonal trends of macroinvertebrates around the

                Apalachicola Bay system.

                C. Results of Field Analyses at East Point

                1. Physicochemical Features

                     The results of the physical and chemical analyses are given in Table

                6. station distribution is shown in Figure 13. The extreme differences in

                salinity reflect rapid changes due, probably, to tidal effects in the area

                between the two sampling dates, As might be expected for this time of the

                yearg dissolved oxygen levels were relatively high, as were color and tur-

                bidity values. The PH levels were also relatively uniform. These data

                conform to conditions observed previously in the estuary at this time of

                the year.

                2. Sediment Analvses

                     The results of the sediment analyses are given in Table 7. All

                classification of sediment types is based on Briggs (1977). The data

                clearly indicate that sediments. in the dredged, inshore channels are com-

                posed largely of silts. Farther offshorelat the proposed spoil sites (1-29

                3-2), medium sand prevails. This appears to be the case at the end of the

                channel (2-3), at the inshore reference site (4-1), and on the Cat Point

                transect (5-2). Fine sand was noted on the reference transect (4-2, 4-3),

                On the offshore point on the western transect (1-3), and on the inshore

                portion of the Cat Point transect (5-1). As the oyster bars off Cat Point

                were approached, there was an increasingly hard substrate.

                                                     15

                     These data clearly show that dredged areas   proximate to storm water

                 runoff from urban portions of East Point act as  sediment traps for finer
                 particles (ioe*p silt). Such fine particles are also associated with
                 various Pollutants (i.e., oils/greases, nutrients, metals) (see above).

                 The combination of dredging and human activities have contributed to the

                 pollution in the East Point portion of St. George Soundy and this area clo-

                 sely resembles that along the Two-mile Channel and the Gulf Intra-coastal

                 Waterway in terms of sediment type and quality.

                 3. Benthic Macroinvertebrates

                     Resuls of the biological  survey are given in Table 8. Inshore dredged

                 channels characterized by pollutant-laden silts (1-11 1-3) were almost

                 devoid of macroiuvertebrates. The dredged channel (inshore; 2-1, 2-2)     also

                 was depauperate of such infauna with recovery noted at the end of the    chan-

                 nel (2-3). This pattern is consistent with the sediment analysis (Table

                 7). The highest numbers of organisms were taken on the inshore station    of

                 the reference transect (4-1). In an unpolluted near-shore system charac-

                 terized by medium sand, such a community should be optimal in terms of

                 productivity, standing crop, and species richness. Farther offshore, in

                 areas characterized by fine sand (4-2, 4-3; 5-1), the biota is charac-

                 terized by moderate to low numbers of individuals and moderate numbers of

                 species. This situation, also, is consistent with what we    know about

                 macroinvertebrate (infaunal) distributiono Areas of recovery, which
                 include the proposed spoil areas (1-2, 3-2), are characterized by relati-

                 vely high number of individuals and species. The reduction of toxic
                 impact, together with high nutrient and organic inputt often leads to such
                 increases of macrofauna in such recovery areas. Even in fine sand (1-3),

                                                        16

                 the nutrient recovery zones is characterized by high numbers of individuals

                 and species*

                       Cluster analysis of the data (log numbers of individuals and

                 untransformed data) corroborate the generalizations noted above.         Station

                                                                      -2
                 1-1 was  generally by itself while stations 2-19 2 j and 3-1      were   closely

                 associated.   In this way, the siltyp polluted areas     showed the sane general

                 form and distribution of benthic infaunal species.       Recovery areas (1-21,

                 1-3, 3-2) were associated with inshore reference areas (4-1) and offshore

                 recovery areas in the dredged channel (2-3). Offshore reference points

                 (4-2, 4-3; 5-1, 5-2) formed associated clusters as might be expected.         In

                 this wayp the benthic macroinvertebrates are good indicators of natural

                 envirortmental conditions and  human activities in the area.

                       Further analysis of the  biological data (Table 10) indicate that the

                 lowest Shannon diversity indices (AH) (as well as other community indices)

                 occurred 'at stations 1-1, 2-11   2-29 and 3-1. Such indices give further

                 proof of the biological response to dredging and urban runoff as noted

                 above. When compared with those from other areas of the bay (Table 4v

                 ?igure 12)p these data appear to show that the above areas are biologically

                 stressed and that such areas correspond to concentrations of silt and

                 pollutants as indicated elsewhere in this report. There is an almost

                 direct association of urban buildup with damage to the biological
                 integrity of St. George Sound.

                 M. Estimation of Impact of       the Proposed Breakwater and Dredge/Spoil

                        Projects

                       Based on the available informationg certain qualified estimates can be

                 made  concerning the environmental impact of the proposed breakwater and

                                                    17

                dredging/ spoiling projects on the Apalachicola Bay system. St. George

                Sound, in the area of urban runoff from East Point and previous dredging
                and spoiling, shows all the signs of a seriously polluted system..

                Crassbeds are lackingg and the effects of point and non-point urban

                runofft heavy boat traffic, and dredging have contributed to the elimina-

                tion of the biological integrity of inshore portions of the system,

                     Construction of the East Point Breakwater will eliminate all benthic

                organisms in areas of construction. Such losses should be partially offset

                by the increased habitat of the breakwater itself. Inshore areas (north of

                the breakwater) will probably have slight reductions in water quality in

                terms of organic loading, sedimeutationt etc., as a result of the break-

                vater construction. Such effects will be proportional to the increased

                extent of the breakwater itself. However,, such effets will have a minimal

                impact on the biological organization of the area since such areas are

                already seriously affected by dredging and urban runoff (point and

                nou-poiut) from of East Point. On balance, considering the area and the

                construction activities, the breakwater project (and associatedt limited

                dredging) should have minimal adverse impact on the biota of St. George

                Sound. The sane conclusion can be reached with regard to the imupact of

                the breakwater on the Apalachicola estuary in general, since projected

                effects of the breakwater on the current structure and salinity regime of

                the system should be minimal.

                     An evaluation of the dredging and spoiling associated with maintenance

                Of the East Point Channel (assuming the breakwater is constructed) is more

                cOmPlex. Such an evaluation must, by necessity, be based on relatively few

                data. However, the available information is relatively consistent.

                                                      18

                 Wberever there is a combination of dredging and urban runoff (together with
                 associated boat traffic and related activities), there is a buildup of
                 various pollutants (i.e., nutrients, oils/greases, metals). Su   ch pollu-

                 t&nts appear to be associated with the silt fraction of the sediments.

                 When the sediments are placed at open water spoil sites, there is probably

                 an immediate (temporary) release of nutrients (i.e., nitrogen and
                 phosphorus-based compounds). The metals appear to be tightly bound to the

                 silt particles and elutriate studies indicate that such pollutants do not

                 get released into the water in significant amounts. What happens to the

                 silt in the spoil bank is less clear, but it is probably eroded in time.

                 This effect is offset by the natural high turbidity of the bay and the fact

                 that most indigenous organisms in this portion of the estuary are adapted

                 to heavy siltation and highly turbid conditions. Consequently, except in

                 areas dominated by grassbeds or oyster bars, the effects of.spoiliug will

                 probably be limited to the immediate spoil site and nearby   (or adjacent)

                 areas. Because of the rapid rate of reproduction and recruitment of asso-

                 ciated benthic macroinvertebrates in soft -sediment areas, biological

                 recovery of the spoil bank would probably occur on a seasonal basis.

                      Specific exceptions to the above generalizations would apply in    case

                 there are alterations in current structure or salinity regime due to    open

                 water spoiling. Such is not the case here. The exact envirot    mental

                 effects of the dredging and spoiling depend not only on the nature and

                 extent of such activities but on the specific area in question. There is

                 no doubt that all adverse effects (temporary and long-term) of open water

                 spoiling can be eliminated by upland disposal of the spoils. Assuming that
                 the upland disposal site is suitable for such a purpose, this option will

                                                     19

                 ,gually be the most desirable alternative. in terms of reduction of habitat
                 destruction and elimination of associated adverse effects in the subject

                 aquatic system.-
                      With respect to the deposition of spoil taken from the East Point

                 channel and placed south of the breakwater, there will be a loss of benthic.

                 productivity in the immediate spoil areas. Such loss will be proportional
                 to the type and amount of spoil and the frequency of deposition. Using the.
                 tiven conditions or estimates of, activity (i.e.9 50pOOO cubic yards at
                 18-month intervals), such spoiling will have an adverse (i.e.., smothering)

                 impact on the benthic organization at spoil sites. Such organization is

                 currently composed of a diverse and productive soft-sediment community.

                 Because it is a relatively turbid, high-energy area (relative to other por-

                 tions of the sytem), devoid. of grassbeds and producing oyster bars in the

                 immediate vicinityp the effects of such an operation should be temporary
                 and limited to the immediate area of the dr'edging and spoiling activities.

                 Such adverse effects would increase in proportion to the dredging extent.

                 and frequency. Adverse water quality changes should be temporary.

                 Movement of spoil away from the spoil site could have an adverse effect on

                 the biological integrity of the immediate vicinity. For all these reasons,

                 there should be a careful evaluation of the benefits of such an operation

                 to the community at large since indiscriminate dredging and open water

                 spoiling will have adverse effects on the bay. However, because of the

                 various environmental factors concerning the East Point area, there should

                 not be widespread or long-term adverse effects on the water quality in the

                 area and the envirormental impact should be largely restricted to the imme-

                 diate impact area. If for any reason the spoil contaminants should be

                                                    20

                released into the water (and thus be transported to a much broader area),

                such an operation could have more extensive adverse effects on the environ-

                ment of St. George Sound. The available.data do not indicate that this

                will happen, however*
