              This report is produced to inform'Floridians and the EPA about surface water quality conditions
              and trends in Florida. Originally produced in 1978, this report has been updated every two years
              since, and has gone through many changes. The items listed below identify the major format
              changes which distinguish this report from its predecessor.

              ï¿½   Regional Rellorts - The large size of the statewide report (550 pages) necessitated its
                  subdivision into 5 regional reports which correspond roughly with Department of
                  Environmental Protection District Office boundaries (South and Southeast District Office
                  reports are under one cover).
              ï¿½   Watersheds versus Reaches      In 1992 the State's rivers, lakes and,estuaries were subdivided
                  into 1600 'reaches' and the assessment was based on this reach structure, however much of
                  the State's waters were not contained within the reaches. For 1994, the assessed area has been
                  enlarged to cover the entire State by dividing the State into 4400 watersheds. The original
                  1600 reaches remain pretty much intact within the new watersheds, and the terminology now
                  includes watershed and waterbody rather than reach.
              ï¿½   ARC/INFO Water Quality Color Maps-- GIS techniques were used to produce color maps
                  depicting water quality (designated use support) in each river basin. Watersheds were color
                  coded based on good, threatened, fair or poor water quality designations.
              ï¿½   New Nonvoint Source Oualitative Survey - A nonpoint source qualitative @survey was
                  performed in 1988 and has been updated and included in this report for 1994. The survey used
                  the same watersheds which were used to assess the water quality data and the qualitative
                  results were integrated into this report to both supplement the quantitative information and to
                  provide information when no quantitative information was available.
                  Current versus Historic Data - Water quality data were examined for two time periods:
                  current data from 1989-1993 and historic data from 1970-1988. Flistoric datawere used to
                  assess waterbodies only when there was no current data available.

             We would like to express our gratitude to all of the professionals that supplied us with water
             quality data and reports, responded to surveys, and answered telephone inquiries concerning the
             status of waterbodies in their area. The quality of this report has been greatly enhanced by their
             efforts.


             A committee thoroughly reviewed and commented on the 1992 305 (b) report and their
             comments were incorporated into this report. Individuals in this committee include: Catherine
             Krestalude, Ernie Frey, Jerry Owen, Lee Banks, Rich Bowman, Jan Brewer, Scott Bulgrun,
             Teresa Frame, Angela Halfacre, Mike Hollingsworth, Amy Kalmbacher, Tim Mckelvey, Mary
             Nogas, Lindy Payne, and Jim Wright of the Northeast District; Rob Mattson of the Suwannee
             River Water Management; District, John Hendrickson of the St. Johns Water Management
             District: and Betsy Deuerling, Don Roberson, Allan Flood and Margaret Walsh of the City of
             Jacksonville.


             The Nonpoint Source Stormwater Section put in a tremendous amount of work on the 1994
             Nonpoint Source Assessment Survey. This team included Kent Cain, Ellen McCarron, and Mike
             Scheinkman. Don Foose, recently retired from the USGS , spent four years delineating and
             digitizing the new watersheds. Bernadette Howe, formerly with the St. Johns River Water
             Management District, provided much of the foundation work on GIS techniques for handling
             watersheds and water quality data and mapping the information.

             Several of the DEP Tallahassee staff are to be thanked for their support and review of the final
             document including Don Axelrad, Vivian Garfein, Mark Latch and Richard Harvey, and Machelle
             Jarmon, who produced numerous draft copies of this text.

              The 3 05(b), Technical Report provides useful surface water quality related information in a. format
              that is helpful-to managers, planners, permit staff, and laymen, as well as water quality experts.
              For each.of the 52 basins, a narrative summary, a map, and data tables identify the quality and
              trends. of Florida's waterbodies, the causes of water quality problems, and the present regulatory
              activities, conducted by DEP and EPA to improve the.problem areas. It is the most widely
              circulated water quality assessment in the State, and also serves as the support document for the
              Surface Water Section of the 1994 305(b) Water Qualfty Assessment Main Report submitted'to
              EPA.

              The assessment required analysis of the available STO-RET water quality data for the 1970-1993.
              time period (STORET is EPA!s computerized water quality database). Data from approximately
              4,000 stations are assessed in this report, necessitating the extensive use of computerized
              assessment techniques. Water quality assessment techniques used to identify problem areas
              included: water quality indices, screening level exceedances, statistical trend analysis,, information
              from special studies, and interviewing local experts. The 305(b) assessmentalso includes
              information from the 1994 DEP Nonpoint Source Assessment Survey (which is based on the.
              responses of 50 Florida agencies).

                                          Statewide Results From the Main Report

              In the 1992 305(b) assessment report, Florida was subdivided into 1600 reaches which were
              based on EPA's RF2 (river reach file #2). A reach was defined as a 5 mile long section of river, or
              5 square mile section of lake or estuary. Only major waterbodies were assessed in the 1992 report:
              due to the resolution limitations imposed by the RF2 file. For 1994, Florida has been subdivided
              into 4400 watersheds based. on EPX s- RF3, and USGS watershed delineations. Many more miles
              of Florida waterbodies were assessed (50% more river miles, 30% more, lake miles, and 20%
              more estuary miles) due to the increased number of watersheds available for assessment and due
              to efforts to collect more. ambient data and store the data into STORET. Table- I and Figure I
              show the mileages of Florida waters which were assessed in this year's report. A striking feature
              shown in.Figure I is that 77% of river miles have unknown quality. This large, percentage- is due,
              to the fact. that EPA classified Florida's many ditches and canals as. rivers, which were@ not
              assessed in this report.

              A quantitative summary of the State's water quality was accomplished by determining the degree
              of designated use support for the different waterbody types. The vast majority of assessed Florida
              waterbodies meet or partially meet their designated use (92% of the river-miles, 81% of the lake
              miles, and 96% of the estuary miles). Figure 2 shows that the river and estuary results are fairly
              similar, however the lake results show generally worse overall quality than the rivers and estuaries
              with fewer miles in the "meets use" category and more miles in the "does, not meet use" category.
              Interestingly -enough, this year's lake assessment brought in many more small lakes with good
              overall quality, however, Florida's largest lakes (Lake Okeechobee and Lake George) still
              overwhelm the State average with their large mileages 6f fair to poor quality.


                                                                                                                     Vi









                 It is very important to address both the sources of pollution and trends in water quality. In the
                 past, the majority of identified water quality problems in the State were caused by point sources,
                 including both domestic and industrial sources. Recently, however, nonpoint sources accounted
                 for the majority of Florida's water quality problems. This is due to the fact that point source
                 treatment processes have improved while there has been an increase in acreage of agricultural and
                 urban developed land and their associated runoff.

                 Water quality trend analysis was performed on waterbodies which had sufficient data for analysis
                 (467 out of 4400 waterbodies). The majority (70%) of these waterbodies (as seen in Figure 3)
                 exhibited no significant trends. Five times as many waterbodies (241/6) have improving water
                 quality trends as have degrading trends. The improved water quality trends were generally the
                 result of wastewater treatment plant upgrades or the additions of new regional WWT?s and
                 nonpoint source controls in Tampa, Orlando and several other cities (as seen in Figure 4). Five
                 percent of the waterbodies assessed for trends showed degrading trends; however, there are no
                 regional patterns for degrading trends similar to the improving trends. The causes of degrading
                 trends included point sources and nonpoint sources. Statewide trend detection is limited for the
                 following reasons:

                          1.    Only one-tenth of the waterbodies are assessed for trends.
                          2.    The primary focus of our monitoring network is not trend assessment; most of our
                                stations are frequently moved, and there are very few sites with long-term, monthly
                                data.
                          3.    Our trend assessment technique is tailored to the problem identified in #2, thus, it
                                only identified relatively drastic changes in water quality. Subtle water quality
                                changes due to population growth or nonpoint source treatment improvements are
                                not picked up by this analysis.

               Florida!s surface water quality is displayed on the map on the cover of the main report. Two
               important conclusions can be drawn from this figure: first, the majority of Florida!s surface water
               has good quality; and second, the majority of problems are found in Central and South Florida.

               The sparsely populated northwest and west-central sections of the State have relatively better
               water quality than other areas. Water quality problem areas in the State are evident around the
               densely populated, major urban areas including: Jacksonville, Orlando, Tampa, Pensacola, the
               Cape Kennedy area and the southeastern Florida coast. Other areas of poor water quality, not
               associated with population, are found in basins with intense agricultural usage.

               Pollution sources and problems in Florida are varied. The State does not have extensive
               industrialization, but rather localized concentrations of heavy industry centered mostly in urban
               areas. Many of the problems found in surface waters in urban areas can be attributed to industrial
               discharges. Silviculture, agriculture and various types of animal husbandry are a large part of
               Florida!s current and historical economy. Furthermore, Florida has undergone rapid population
               growth over the past two decades and this continues. This has resulted in more pollution sources
               associated with residential development.

               Florida's major surface water quality problems can be summarized into five general categories:

                       I .  Urban Stormwater. Stormwater carries a wide variety of pollutants from nutrients to
               toxicants. Siltation and turbidity associated with construction activities can also be a major
               problem. Problem areas are concentrated around urban centers and mirror, quite well, the
               population map of the State. Current stormwater rules and growth management laws address this
               problem for new sources, but are difficult to monitor and enforce.

                       2.   Ap-ricultural Runoff. The major pollutants involved include nutrients, turbidity,
               BOD, bacteria and herbicides/pesticides. These pollutants generally do their worst damage in
               lakes and slow moving rivers and canals, and sometimes, the receiving estuary. Problems are
               concentrated in the central and southern portions of the State, and in several of the rivers entering
               the State from the north. Traditionally, agricultural operations have had far more lenient
               regulation than point sources; however, there is increasing recognition of the need for improved
               treatment of runoff water.


                       3. Domestic Wastewater. This is an area that has shown significant improvement in the
               last decade. Most of the waterbodies with improving water quality trends can be traced to
               wastewater treatment plant (WWTP) upgrades. Further advancements are being encouraged with
               design innovations such as wastewater discharge to wetlands, water reuse and advanced
               treatment. Still, a problem exists in the rural areas of the State where financial and technological
               resources are limited. Consequently, several of these poorly operating facilities are polluting
               some of Florida's relatively pristine natural waterbodies. Also, septic tank leachate contributes to
               the degradation of many of Florida's waterbodies.

                      4. Industrial Wastewater. Most notable among these are the pulp and paper mills.
               Because of the volume and nature of their discharge, all of the pulp and paper mills operating in
               the State seriously degrade their receiving waters. The phosphate and fertilizer industries are

                                                                                                                    Xi







             mejor pollution sources (both point and nonpoint) in several of Florida's surface water basins. In
             EAdition, the mining of phosphate causes surface water hydrological modifications and major land
             ust@ di_,@Urbances.


                     5. H                                                 orm of damming running waters,
                           ydrological Modifications. This can take the f
             channelizing slow@moving waters, or dredging, draining and fillingwetlands. Such modifications
             are not. strictly pollution sources. However, in most cases. where the natural hydrological regime
             was modified'(mostly for water quantity purposes) water quality problems have ensued. Rating
             th,- effect of hydrologic modification is difficult. Dredge and fill activities result in a loss of
              lni7citat. Disruption of wetlands with a resultant net loss of area reduces the buffering and filtering
             capacities and biological potential of wetlands. This is a particularly important problem in
             estuaries. The loss of seagrasses and other marine habitats can seriously affect the maintenance of
             a viable fishery.


             The assessment of public health and aquatic life impacts uncovered several areas of concern.
             Many of these- problems are associated with estuaries and are of a persistent nature. Fish with
             Ulcerative Disease Syndrome -are still present in the lower St. Johns River. This problem was first
             identified in the early to mid-80s. Second, major fish kills (as many as I million fish) occurred in
             the Pensacola Bay system over the past two years. The more massive of these kills occurred, in
             Bayou Chico. Bacterial contan-dnation in the water and contaminated sediments of the Mami,
             River threaten Biscayne. Bay. Many urban estuaries throughout the State. have elevated levels of
             metals and organic contaminants in their sediments. Examples are Tampa Bay, St. Johns River
             Estuary and Pensacola Bay. The continued loss of fishery habitat from dredge and fill and
             construction activities is a threat to the maintenance of a: viable fishery. The extensive die off of
             mangroves and seagrasses and algal blooms in Florida Bay are an important State concern. The-
             probable cause is the extensive channelization and hydrological modification of the bay's
             watershed exacerbated in recent years by a lack of flushing from hurricanes, high water
             temperature and high salinity.

             On the positive side, seagrasses have increased in area in Tampa Bay and there has been an
             improvement in water quality in Hillsborough Bay.

             Three other problems exist which are also of a persistent nature, but largely impact fresh water
             systems. First, fish consumption advisories for largemouth bass continue to be issued because of
             elevated mercury concentrations in their tissue. Second, a no fish consumption advisory has been
             issued for the Fenholloway River. Elevated levels of dioxin were found in fish from this stream.
             This waterbody receives effluent from a pulp mill. The third problem is the coliform bacteria
             contamination of the Miami River. Sources of this contamination are illegal sewer connectiuns to.
             the stormwater pipe system, leaking or broken sewer lines, and direct discharges of raw sewage.
             when pump stations have exceeded their capacity. During acute contamination events (direct
             discharge of sewage) coliform bacteria counts in the Mami River and adjoining waters of
             Biscayne Bay are hundreds of times higher than State criteria. Efforts are being made by the City
             of Miami and Dade County to correct these problems.

                                                                                                             Xii










                                 Northeast Region Basin-by-Basin Evaluation of Water Quality

               The quality of Florida waters is graphically depicted on basin maps which follow each basin
               description. Areas of good, fair, and poor quality are readily discernible on these maps. The
               following is a summary of the status of the quality of waters in northeast Florida:

               The Steinhatchee River basin's major water quality problem area is the Fenholloway River which
               is seriously affected by the effluent from a large paper mifl. Although the discharge quality
               improved in the early seventies, the river still has high nutrients and color and low DO and
               biological diversity. An EPA study indicated impacts to the bay at the mouth of the Fenholloway.
               DEP conducted a use attainability study of the river, and has changed its classification from
               Industrial (Class V) to Recreation (Class III). The upper and lower Suwannee River basins,
               which receive a considerable quantity of ground water spring flow, have good water quality.
               Exceptions are those upper river tributaries that receive mining wastewater from Occidental
               Chemical Company. Sections of the Suwannee below these tributaries have some elevation in
               fluoride and phosphorus concentrations. Other direct threats to the Suwannee include agricultural
               and silviculture runoff, septic tank leachate, and nitrates from dairy farms. Major tributaries of the
               Suwannee are generally of good quality, but are threatened by local pollution sources. The North
               Withlacoochee River receives agricultural runoff and effluent from a paper mill (indirectly), and
               before entering Florida receives discharges of industrial effluent and municipal wastewater. The
               Alapaha River basin has good water quality. The Santa Fe River has several major springs and
               very good water quality. A tributary of the Santa Fe River, New River, receives discharge from a
               WWTP at Raiford and indirectly from the Town of Lake Butler. Bacteria, nutrient, and turbidity
               values are elevated near the discharge. The water quality of the Santa Fe River below New River
               reflects the reduced quality of the New River. Alligator Lake in the upper basin is degraded from
               the Lake City WWTP discharge and urban runoff and is the focus of a SWIM study. Lake Rowell
               (in the Santa Fe basin) has a eutrophication problem.


               In general, the St. Marys River has good water quality. The South Prong of the St. Marys, Little
               St. Marys River, and Turkey Creek receive effluents from WWTP. 11istorically, problems of low
               DO, high nutrient levels, and high bacteria counts were present. Several pulp mill operations are
               located near the mouth of the river and along the estuarine Amelia River. Nassau River has good
               water quality except for Mills Creek which receives dairy farm runoff.


               Downstream of Lake George, the St. Johns River is wide, shallow and sluggish with frequent,
               tidally influenced reverse flows. Many of the tributary systems have water quality problems which
               impact the river. Agricultural runoff and domestic discharge affect the Haw Creek/Crescent Lake
               tributary drainage. A paper mill causes problems in the Rice Creek tributary system. Agricultural
               and urban runoff affect Black Creek and Peters Creek. The Julington Creek, Durbin Creek, and

                                                                                                                     XW







             Doctors Lake watersheds are highly developed and water quality problems due to urban runoff
             and septic tank leachate are evident.

             Water quality problems arising ftorn septic tank leachate and WMrTP discharge are common
             throughout the Jacksonville area of the river and its tributaries. In addition, numerous industries
             discharge to the river system. As a result, most of the tributaries, notably the Ortega, Cedar and
             Trout Rivers, have fair to poor water quality from Lake George to its mouth due to the polluted
             tributaries, direct discharge and significant urban runoff. A persistent problem in the lower St.
             JoIms basin has been the presence of fish with Ulcerative Disease Syndrome.


             The east coast estuarine waters from Jacksonville to Ft. Pierce have localized impacts from
             wastewater discharges, stormwater runoff, causeways which reduce hydraulic flushing, and
             shoreline vegetation disruption. Areas of greatest impact are the intracoastal waterway near Palm
             Valley (below Jacksonville Beach), the Matanzas River at St. Augustine, and the Halifax River
             between Ormond Beach and Port Orange.

                                   INTRODUCTION AND M@THODS


                   This section describes the water quality assessment procedures used by the Bureau of
                   Surface Water Management to prepare the 1994 Florida Water Quality Inventory
                   [305(b)].  The procedures are:



                           I .     Divide State into Assessment Watersheds.
                           2.      Inventory STORET data.
                           3.      Calculate Stream Water Quality Index (WQI).
                           4.      Calculate Lake/Estuary Trophic State Index (TSI).
                           5.      Apply Screening Levels.
                           6.      Conduct Trend Analysis.
                           7.      Conduct Toxic Pollutant Assessment.
                           8.      Conduct Nonpoint Source Assessment.

                   Florida's 52 major river basins were subdivided into 4400 watersheds of approximately
                   five square miles each. The predominate watterbody within each watershed was identified
                   and classified as a lake, stream, or estuary. Each watershed and its waterbody formed an
                   assessment unit and all water quality stations within the watershed were aggregated as if
                   they were from the same site (the stations were screened for unwanted sites, such as, point
                   source discharge sites). A water quality inventory was performed on EPA!s STORET
                   database. The inventory included the years 1970 through 1993 and was classified as
                   recent (1989-1993) or historic (1970-1988). Tables of water quality data were prepared
                   for each of Florida!s 52 basins. Three procedures were then used to assess the water
                   quality data. A Water Quality Index was calculated to determine the overall quality of
                   Florida streams and rivers. The Water Quality Index summarizes information from six
                   categories including water clarity (turbidity and total suspended solids), dissolved oxygen,
                   oxygen demanding substances (biochemical oxygen demand, chemical oxygen demand,
                   and total organic carbon), nutrients (total nitrogen and total phosphorus), bacteria (total
                   coliform and fecal coliform), and macroinvertebrate diversity index (based on natural
                   substrate samples, artificial substrate samples and Beck's Biotic Index). The water quality
                   of lakes and estuaries is described by the Trophic State Index which is a measure of the
                   potential for algal or aquatic weed growth. The components which make up the Trophic
                   State Index include total nitrogen, total phosphorus, chlorophyll and Secchi depth.
                   Screening levels for 19 water quality parameters were also used to determine the quality
                   of Florida lakes, estuaries and streams.

                   The water quality indices and screening levels have all been tailored to Florida's water
                   quality by using the actual distribution of Florida data to determine the water quality
                   criteria used by the procedures. Specific information on each of the procedures is
                   described in the following sections.










                                               Watershed as the Assessment Unit


                  In the 1992 305(b) assessment report, Florida was subdivided into 1600 reaches which
                  were based on EPA's RF2 (river reach file #2). A reach was defined as a 5 mile long
                  section of river, or 5 square mile section of lake or estuary. Only major waterb6dies were
                  assessed in the 1992 report due to the resolution limitations imposed by the RF2 file. For
                  1994, Florida has been subdivided into 4400 watersheds based on EPA's RF3 and USGS
                  watershed delineations. The original 1600 reach delineations have been kept intact,
                  however, many additional watersheds have been added due to the increased resolution of
                  RF3 and the USGS watersheds which cover the entire State. USGS was contracted to
                  develop useable, small watersheds (approximately 5 square miles) using watershed
                  boundaries identified on USGS topological maps and ARC/INFO GIS techniques. USGS
                  completed 75% of the State, but unfortunately they did not delineate watersheds in south
                  Florida (USGS subregion 0309). Watersheds for South Florida were adapted from a
                  much coarser delineation developed by the South Florida Water Management District. The
                  resulting watersheds in this area are about 50 square miles each, ten times larger than
                  those for the rest of the State.


                  The major waterbody within each watershed was identified and named. Usually each
                  watershed encompassed one major or one minor named waterbody (similar to the 1992
                  reach structure). The length of each stream waterbody and the area of lake and estuary
                  waterbodies is essential information. The length of stream waterbodies was determined by
                  GIS measurements of the RF3 trace ( or assigned a length of 5 miles if no RF3 trace was
                  avOable). The area of lake and estuary waterbodies was determined with crude GIS aerial
                  measurement techniques (if estuary waterbodies had no RF3 traces, their area was set to
                  5 square miles and unknown lake waterbodies were assigned an area of I square mile).
                  The water quality within each waterbody is assumed to be homogenous (if data prove this
                  assumption to be wrong, then the waterbody was subdivided). GIS techniques were used
                  to assign STORET sites to their respective watersheds and the location of each site was
                  visually inspected on a GIS map. If more than one named waterbody showed up in a
                  watershed (based on the STORET data within a watershed), then the watershed was
                  subdivided.
                                                     Inventory of STORET Data

                  An inventory of data was retrieved from STORET for the 1970-1993 time period. If data
                  within a watershed were available for the current time period (defined as 1989-1993), then
                  historical data was not examined, except for trend analysis. If no current data were found,
                  then historic data (defined as 1970-1988) were used for the assessment. Fifty STORET
                  parameter codes representing 21 different water quality parameters were inventoried
                  (Table 3). There are about 8000 Florida stations in STORET which were sampled in
                  1970-1993. These stations are located in 1500 of the 4400 watersheds. Annual average
                  (median) water quality was calculated for each of these stations and the data were stored
                  on a local EBM Personal computer. In order for an annual average to be calculated for a
                  station, the station had to be sampled at least twice within each year. STORET remark

                   codes also present a problem in data analysis when a data     value is recorded as "less than"
                   the actual value reported. In these cases the reported value was multiplied by 0.5 to adjust
                   for the "less than" condition. Data with STORET remark codes indicating that the
                   reported value was "greater than" the actual value were dropped from further analysis. A
                   Water Quality Index value was calculated for each stream/river annual median and a
                   Trophic State Index value was calculated for each lake/estuary annual median.

                                              Florida Stream Water Quality Index Procedure

                   To assess Florida stream water quality, a Florida stream Water Quality Index (WQI) was
                   developed and first used in the 1988 305(b) report. The WQI is based on the quality of
                   water as measured by six water quality categorie& (water clarity, dissolved oxygen, oxygen
                   demanding substances, bacteria, nutrients and biological diversity). Each category may
                   have more than one parameter as shown in Table 4. Raw (annual average) data are
                   converted into index values which range from 0 to 99 for the six categories. Index values
                   correspond to the percentile distribution of stream water quality data in Florida (Table 4).
                   [The percentile distribution of STORET water quality data were determined in 1987 for
                   2,000 ambient, stream STORET locations in Florida.] For example, Table 4 shows the
                   BOD concentrations ranged from 0.8 mg/1 (10 percentile) to 5.1 mg/ (90 percentile) with
                   a median value of 1.5 mg/1 (50 percentile). A BOD concentration of 0 to less than 0.8
                   mg/1 is assigned an index value of 0 to 9, etc.

                   The overall WQI is the arithmetic average of the six water quality index categories. The
                   index for each category is determined by averaging its component parameter index values.
                   NEssing water quality parameters and missing water quality categories are ignored in the
                   final calculation. Therefore, the final WQI is based on an average of anywhere from I to 6
                   water quality index categories. Table 5 shows an example calculation of the WQL The
                   WQ1 can be calculated from just one index category; however, it becomes more reliable as
                   more categories are used in its calculation.

                   In order to determine the range of values of the WQI which correspond to good, fair and
                   poor quality, the WQI was correlated with the EPA National Profiles Water Quality
                   Index for Florida data. (The EPA WQI was used in the 1986 305(b)). Based on this
                   correlation, the cutoff values for the WQI were determined as follows: 0 to less than 45
                   represents good quality, 45 to less than 60 represents fair quality, and 60 to 99 represents
                   poor quality.

                   The Florida stream Water Quality Index has several advantages over indices used
                   previously. First, the index is tailored to Florida water quality data, since it is based on the
                   percentile distribution of Florida stream data. Second, it uses the water quality categories
                   which are felt to be the most important measures of water quality in Florida: water clarity,
                   dissolved oxygen, oxygen demanding substances, nutrients, bacteria and biological
                   diversity. Third, it is simple to understand and calculate and does not require a mainframe
                   computer or any complex data transformations or averaging schemes. Finally, the index



                                                                                                                          5

                  works; it nicely identifies areas of good, fair, and poor water quality that correspond to
                  professional and public opinion.

                  A toxic pollutants category would be a valuable addition to the index; however, toxic
                  pollutants were not included in the index since there is relatively little data in Florida
                  (compared to the amount of data for conventional pollutants ). Toxic pollutants were
                  assessed separately as discussed later in this section of the report.

                                                      Trophic State Index Procedure

                  The Trophic State Index procedure provides an effective method of classifying lakes
                  based on the lake's chlorophyll, Secchi depth, nitrogen and phosphorus concentrations.
                  The index was developed in 1982 in response to the EPA Clean Lakes Program and is
                  documented in the Classification of Florida Lakes Report by the University of Florida,
                  Department of Environmental Engineering Sciences. This index remains unchanged from
                  the 1988 305(b) report.

                  The index is based on a trophic classification scheme developed in 1977 by R.E. Carlson.
                  It relies on three trophic indicators to describe the trophic status of a lake. The goal was
                  to have each indicator relate to algal biomass such that a 10 unit change in the index
                  would represent a doubling or halving of algal biomass. Carlson developed indices based
                  on Secchi disc transparency, chlorophyll concentration and total phosphorus'
                  concentration. The Florida Trophic State Index (TSI) is based on the same rationale, but
                  also includes total nitrogen concentration as a fourth index. Criteria were developed for
                  Florida lakes from a regression analysis of data on 313 Florida lakes. The desirable upper
                  limit for the index is set at 20 ug/l chlorophyll which corresponds to an index of 60.
                  Doubling the chlorophyll concentration to 40 ug/l results in an index increase to 70 which
                  is the cutoff for undesirable (or poor) lake quality. Index values from 60 to 69 represent
                  'fair' water quality. The criteria for chlorophyll, Secchi depth, total phosphorus and total
                  nitrogen concentrations are shown in Table 6.

                  A nutrient index is also calculated based on phosphorus and nitrogen concentrations and
                  the limiting nutrient concept. The lirr@iting nutrient concept identifies a lake as phosphorus
                  limited if the nitrogen to phosphorus concentration ratio is greater than 30, as nitrogen
                  limited if the ratio is less than 10, and balanced (depending on both nitrogen and
                  phosphorus) if the ratio is 10-30. Thus, the nutrient TSI is based solely on phosphorus if
                  the ratio is greater than 3 0, solely on nitrogen if less than 10, or based on both nitrogen
                  and phosphorus if the ratio is between 10 and 30. An overall index (TSI) is calculated
                  based on the average of the chlorophyll TSI, the Secchi depth TSI and the nutrient TSI.
                  For this index to be calculated, both nitrogen and phosphorus measurements are required
                  for the sample. The lake trophic state index was also applied to Florida estuaries to
                  describe estuarine water quality. The criteria for the estuary quality ratings is 10 less than
                  the lake ratings (i.e., good estuarine water quality is a TSI value of 0-49, fair quality is 50-
                  59, and poor quality is a value of 60-100). Table 7 shows an example TSI calculation.

                                                           Screening Levels

                  Screening levels were used to determine water quality problems caused by each of
                  nineteen water quality parameters (Table 8). Screening levels were based on either Florida
                  criteria or on criteria established by professional judgment when quantitative Florida
                  criteria are absent. Different screening levels were developed for streams, lakes and
                  estuaries to take into account the natural differences among these waterbodies. The
                  criteria which were established by professional judgment were based on the percentile
                  distribution of Florida data.


                  The eightieth percentile was chosen as the cutoff between acceptable and unacceptable
                  water quality. This means that 80% of Florida's water quality data will have acceptable
                  levels. Table 8 identifies the screening levels used, the typical values measured and the
                  Florida criteria for streams, lakes and estuaries. Screening level exceedances are noted in
                  the data tables for each watershed in each basin.


                                                            Trend Analysis

                  Water quality trend analysis was performed on 12 water quality parameters (plus the
                  overall stream water quality index and the trophic state index) for 460 watersheds. The
                  time frame for the analysis is from 1984-1993. The analysis was quite simple; a non-
                  parametric correlation analysis (Spearman's Ranked Correlation) was used to analyze the
                  ten-year trend of the annual STORET station medians for each watershed. There may
                  have been only one station analyzed within a watershed resulting in a maximum of ten
                  years of data, or there may have been many stations sampled within the watershed
                  resulting in the analysis of many more yearly station medians and a more meaningful trend
                  analysis.

                  A separate trend assessment technique was used to analyze stream, lake, and estuary
                  waterbodies. Stream trend analysis utilized the trend information from eight water quality
                  parameters (bacteria, turbidity, total suspended solids, BOD, dissolved oxygen, Secchi
                  depth, nitrogen and phosphorus) plus the overall water quality index. Lake and estuary
                  trend analysis focused on four trophic state parameters (chlorophyll, Secchi depth,
                  nitrogen and phosphorus) plus the trophic state index.

                  The overall trend of each waterbody was determined by comparing the number of
                  improved water quality parameters to the number of degraded water quality parameters.
                  Some waterbodies showed quite strong trends. If a waterbody showed no trends, or just
                  one parameter showed a trend (or the number of improved trends minus the number of
                  degraded trends is zero or one), then the trend is classified as "no change". This trend
                  analysis must be considered preliminary due to the simplicity of the technique.

                                                      Toxic Pollutant Assessment


                  The assessment of toxic pollutants in Florida's waters was accomplished by an inventory
                  of 9 STORET toxic metal parameters for 1991-93 (Table 9). The Florida surface water
                  quality standards (Chapter 17-302, Florida Administrative Code) were used to assess
                  whether the toxic pollutant was found at an elevated level. Several standards are based on
                  hardness levels, however, since hardness levels were not available in all cases, a hardness
                  value of 100 mg/I as calcium carbonate was assumed. An elevated level was defined as
                  any exceedance of the standard for any of the nine metals. Generally, each waterbody was
                  sampled two or three times for several of the metals during the last three years.

                                                     Nonpoint Source Assessment

                  An extensive assessment of nonpoint source impacts on Florida's waters was conducted in
                  1988 through the use of a questionnaire sent to all major State agencies (Water
                  Management Districts, Division of Forestry, Game and Fresh Water Fish Commission),
                  city and county offices, U.S. Soil Conservation Service, U.S. Forestry Service, Regional
                  Planning Councils, local Soil and Water Conservation Districts, citizen environmental
                  groups (Sierra Clubs, Audubon Society and others) and professional outdoor guides. The
                  respondents (approximately 150 agencies and 350-400 participants) to the questionnaire
                  identified nonpoint sources of pollution, environmental pollution symptoms (fish kills,
                  algal blooms, etc.) pollutants and miscellaneous comments. The assessment has been
                  updated in 1994. The 1994 nonpoint source assessment was performed more efficiently
                  than the 1988 version due largely to the use of GIS technology for compiling and
                  displaying the data, and also advancements in the questionnaire methodology. Scannable
                  forms were used eliminating the need to key punch data and integration with the 305b
                  report was much improved.

                  Florida's 1994 nonpoint source assessment was performed using a qualitative, best
                  professional judgment approach. Unlike point source pollution analysis and its readily
                  available STORET ambient data, there is rarely any convenient database of water quality
                  monitoring data that has been designed for analyzing impacts of nonpoint source pollution
                  on surface waters. Therefore, the assessment procedure was designed to make use of the
                  knowledge of experienced field personnel who had information about individual
                  waterbodies. The 1994 survey was sent to essentially the same group of professionals as
                  the 1988 report and approximately fifty respondents identified nonpoint sources of
                  pollution, environmental symptoms of pollution (fish kills, algal blooms, etc.), degree of
                  impairment (rating) of a waterbody and miscellaneous comments. A total of 1720
                  watersheds or about 40 % of the total watersheds were qualitatively assessed by the
                  respondents. Data tables summarizing the 1994 NPS survey are presented for each basin
                  in this report. The remainder of this section describes the information presented in these
                  tables.

                  The impairment rating of a waterbody was defined as status of waters within a watershed
                  as determined by support or nonsupport of designated use. The status of a watershed was
                  dependent on making a determination of designated use support that applied to all surface
                  waters within the aerial extent of that watershed. Designated use refers to the
                  classification or standards and criteria applied to all Florida waters.

                  Impairment rating categories used were as follows:

                           I .    Good (meets designated use). All surface waters in the watershed are
                                  supporting their use classification with no evidence of nonpoint source
                                  problems.
                           2.     Threatened (meets designated use). All surface waters in the watershed are
                                  attaining their use classification, but in the absence of any future
                                  management activities, it is suspected that within five years at least some of
                                  the surface waters in the watershed will not support their designated use.
                           3.     Fair (partially meets designated use). Some, but not all, surface waters in
                                  the watershed are not supporting their designated use.
                           4.     Poor (does not meet use). All surfacewaters in the watershed are not
                                  supporting their designated use.

                  Nonpoint source pollution is generally associated with land use activities which do not
                  have a well-defined point of discharge, such as discharge from a pipe or smoke stack.
                  Nonpoint contaminants are carried to waterbodies by direct runoff or percolation through
                  the soil to groundwater. There are many different potential source areas. Some of the
                  common activities and sources which were considered in the nonpoint source assessment
                  include: 1.     Construction site runoff. This type of source can provide sediment,
                                  chemicals and debris to surface waters.
                           2.     Urban stormwater. Runoff from buildings, streets and parking lots carries
                                  with it oil, grease, metals, fertilizers and other pollutants.
                           3.     Land disposal. Leachate from septic tanks and landfills may pollute
                                  groundwater or local surface waters. Contamination of surface waters can
                                  be by either by direct runoff or discharge from groundwater.
                           4.     Agricultural runoff. Runoff from fields and pastures carries with it
                                  sediments, pesticides and animal wastes ( which can be a source of bacteria
                                  and viruses and nutrients).
                           5.     Silvaculture operations. Logging activities which erode forest soils add
                                  turbidity and suspended solids to local surface waters.
                           6.     Mining. This type of activity can cause siltation in nearby waterbodies,

                     7.    Hydrologic modification. Dams, canals, channelization and other
                           alternations to the flow of a waterbody result in habitat destruction and in
                           general water quality deterioration.

              Abbreviations were used for the nonpoint source categories in the NPS data tables which
              are found in each basin write-up on the following pages. Those abbreviations correspond
              to the sources as described below:


                     AG          Agricultural runoff
                     RE          Resource extraction or mining
                     SL          Silvaculture or for operations

                     STP         Sewage treatment plant


              Data for the last two point source categories were not obtained from the 1994 NPS
              assessment survey, but rather they come from the 1992 3 05 (b) Report.

              Respondents were provided with 15 choices of pollutants and 9 choices of symptoms for
              use in characterizing the status of a watershed. Pollutant choices or categories and their
              descriptions are provided below:

                     1 .   Nutrients. An imbalance of nitrogen and or phosphorus which resulted in
                           algal blooms or nuisance aquatic plant growth. Standards for Class III
                           waterbodies are based on this criteria.
                     2.    Bacteria. This refers to the presence pf high levels of coliform, strep and
                           enteric fecal organisms which cause the closure of waters to swimming and
                           shellfishing.
                     3.    Sediments. Soil erosion which results in high levels of turbidity.
                     4.    Oil and Grease. Hydrocarbon pollution resulting from highway runoff,
                           marina, and industrial areas. Their presence is evidenced as a sheen on the
                           water surface.
                     5.    Pesticides. These class of chen-dcals can be found in runoff from
                           agricultural lands and some urban areas.
                     6.    Other Chemicals. General category for other chemicals besides pesticides
                           and oil and grease, typically associated with landfills, industrial land uses
                           and hazardous waste sites.





                                                                                            15









                         7.     Debris. This category includes trash ranging from Styrofoarn plates and
                                cups to yard clippings and dead animals.
                         8.     Oxygen Depletion. Low levels of dissolved oxygen in the water column
                                resulting in odor problems (anoxic waters) and fish kills.
                         9.     Salinity. Changes in salinity caused by too much or too little freshwater
                                inflows. Typical results are declines in the fishery and changes in species
                                composition.
                         10.    pH. Change in the acidity of surface waters with resultant declines in
                                fisheries and other changes to flora and fauna, such as reductions in
                                diversity or abundance.
                         11.    Metals. Anthropogenically enriched levels of trace metals commonly
                                associated with urbanized watersheds and marinas.
                         12.    Habitat Alteration. Landuse activities which adversely affect the resident
                                flora and fauna. Included with habitat alteration is habitat loss.
                         13.    Flow Alteration. Landuse activities whicit influence the flow
                                characteristics of a watershed resulting in adverse affects upon flora and
                                fauna.
                         14.    Thermal Pollution. Activity which changes local temperature of receiving
                                water relative to ambient temperature.
                         15.    Other Pollutants. General category used to describe activities and impacts
                                not described in the other 14 categories.

                 Responses of waterbodies to the above listed sources of pollutants were defined as
                 symptoms. The nine symptoms used for categorization are defined as follows:

                         1.     Fish Kills. Dead and dying fish caused by designated source of pollution.
                         2.     Algal Blooms. Excessive growth of algae resulting from nutrient
                                enrichment.
                         3.     Aquatic Plants. Density of exotic and nuisance plants such that impairment
                                of the waterbody occurs. Nutrient enrichment is usually the cause.
                         4.     Turbidity. High suspended sediment loads in water column resulting from
                                soil erosion. Effects on the waterbody include smothering of benthos and
                                reduced light penetration with resultant loss of plant and algal productivity.
                         5.     Odor. Unpleasant smells resulting from low dissolved oxygen conditions
                                (anoxia) and or fish kills.
                         6.     Declining Fisheries. Reduction in landings of or increases in catch per unit
                                effort to catch game and commercial species indicating loss of productive
                                fishery.
                         7.     No Swimming. Closure of recreational swimming areas due to public
                                health risks, usually caused by high coliform bacteria counts.
                         8.     No Fishing. Closure of recreational or commercial fishing areas because of
                                threats to human health from elevated bacteria counts or levels of
                                contaminants.



                                                                                                             16








                         9.      Other Symptoms. General category used for information that cannot be
                                 placed in any other category.






                                                Making Use Support Determinations

                 EPA has revised its criteria for determining the status of waters as documented in
                 Appendix B of the Guidelines for the Preparation of the 1994 State Water Quality
                 Assessments (305(b) Report). Often, a variety of assessment techniques were available for
                 each watershed (e.g., chemical data, biological data and NPS survey results) and in this
                 case a use decision was made based on integrating 01 the information. If quantitative data
                 were available on the water quality of a waterbody (through the Trophic State Index or
                 Water Quality Index) then the designated use of the waterbody was determined from the
                 quantitative information, and if no quantitative data were available, then the qualitative
                 NPS survey results were used to estimate designated use of the waterbody. Current data
                 was available for assessment of about 1100 watersheds, historic data was used in 400
                 watersheds, and qualitative data was used in 1000 watersheds. The NPS survey provided
                 all the information on sources of pollution (e.g. urban or construction runoff) and part of
                 the information on causes and symptoms of pollution. Integrating the information from the
                 quantitative (STORET) analysis and the qualitative NPS survey was not easy, but many
                 additional watersheds were assessed based on the results of the integration. In the future,
                 the two techniques should blend together much better through increased coordination of
                 efforts.

                      In the News


                        A chicken rendering plant was proposed in Georgia near the Alapaha
                        River. It was proposed that wastewater from the plant be sprayed on
                        a 30 acre field 4000 feet from the river. Opponents have expressed
                        concern that runoff would contaminate the river, however, there is
                        no record of impacts to date.

                    Ecological Characterization


                    The Alapaha River basin originates in Georgia and terminates at the Suwanitee River north of the Town
                    of Live Oak in Florida. The basin drains 1840 square miles (376 river miles) of which 100 (18 river
                    miles) are in Florida. The Florida portion of the basin is mostly forest and agricultural land.

                    In Georgia, the river is mostly blackwater with some alluvial runoff. After entering.Florida, it flows into a
                    karst terrain where it is captured by sinkholes during low flow (about half the time). It re-emerges near its
                    confluence with the Suwannee River, most probably as Alapaha Rise Spring or Holton Springs. The
                    underground and groundwater connections buffer the Alapaha to a near-neutral pH. The River
                    contributes an annual average of 15% of the annual flow to the Suwannee River.


                                                                                                                                   18

                    Point sources of pollution to the river located in Georgia are the Cities of Alapaha, Fitzgerald, and
                    Lakeland WWTPs. Within Florida, the City of Jasper WWTP discharges into a tributary, Bell Creek, of
                    the river. The Alapaha River appears to have good water quality in the Florida reach. It flows through
                    rural areas of low intensity agriculture and silviculture. There may be significant habitat impacts since at
                    low flow the dry or semi-dry riverbed is a favorite area for all-terrain vehicle use.

                    The river has been monitored since 1989 by SRMOM as a SV,/TM priority water. The sampling station is
                    located below the river's confluence with the Alapahoochee River near the Town of Jennings.

                  Ecological Characterization

                  The Aucilla River is an exceptional jewel among Florida!s rivers. The Aucilla River and its main
                  tributary, the Wacissa River, are designated Outstanding Florida Waters. Originating in Georgia, the
                  blackwater Aucilla flows approximately 69 miles to the Gulf of Mexico and drains 733 square miles of
                  northern Florida. The headwaters are a series of lakes, swamps, sinkholes and underground passages that
                  eventuafly coalesce into a defined channel. Water quality is characterized by tea-colored water due to
                  natural humic substances. This stretch of the river is a favorite of canoeists as it offers some of Florida's
                  rare river rapids. The river goes underground and, for about 2 miles, is evident only as a series of
                  sinkholes until it reappears about 5 miles downstream in a swampy area around Nutall Rise.


                  The Wacissa River originates from several springs about 15 miles southeast of Tallahassw. This stream
                  runs clear during periods of low rainfall, but becomes tannic during rainy times. It flows through an area
                  abounding in wildlife and diverse vegetation. After about 12 miles, the Wacissa begins to diverge into
                  several braided channels that form a maze of surface and underground passages eventually emptying into
                  the Aucilla near where it emerges. A shallow canal built by Indians and rebuilt by slaves (in the early
                  19th century) provides canoe passage to the Aucilla River through virtually untouched floodplain and
                  swamps.


                  Both the Aucilla and Wacissa are rich in archaeological sites, including prehistoric fossil records and
                  evidence of early Indian settlements. Both river corridors are refuge to many rare and endangered species.
                  Most of the drainage area is in silviculture, and much of the river corridor area is in public ownership.


                                                                                                                                    24









                  The mouth of the Aucilla empties into an expanse of Spartina saltmarsh adjoining the St. Marks National
                  Wildlife Refuge.


                  ARthro
                        Mgenic Impacts


                  The water quality of the river is currently being monitored by DER It was previously sampled in 1987 as
                  part of a Basin Assessment. An integrated comprehensive investigation of water quality and biological
                  resources has not been performed. Water quality appears to be very good in this basin. There are few
                  pollution sources and relatively low impact land uses. The upper reaches of the Aucilla River and the
                  Little Aucilla River are swampy and have little flow. They are naturally low in pH and dissolved oxygen.
                  Consequently, biological diversity is low especially in the Little Aucilla. However, after the stream
                  coalesces into a defined stream, and its flow supplemented by groundwater, biological diversity improves
                  (near Lamont). All reaches below this area normally have levels of pH and DO consistent with unpolluted
                  flowing streams.

                  Although still supporting healthy populations of native aquatic plants, the Wacissa does periodically have
                  areas clogged with Hydrilla and water hyacmth. Also, near where the Wacissa becomes diffuse before
                  reaching the Aucilla, there is an area where cattle have direct access to the water.

                 Ecological Characterization


                 The Upper East Coast basin starts just south of Jacksonville and extends south to New Smyrna Beach.
                 The basin consists of a narrow strip of coastal ridge separating the Atlantic Ocean from a narrow lagoon
                 system and the mainland. These lagoons, called "rivers", connect to the ocean by three inlets and to each
                 other through the Intracoastal Waterway. The three major estuarine "rivers" are the Tolomato River to
                 the north (from St. Augustine to Jacksonville), the Matanzas River in the middle (ICWW from St.
                 Augustine Inlet to Matanzas Inlet), and the Halifax River in the south. The Guana River is another
                 lagoon roughly parallel and seaward of the Tolomato and connected to the Tolomato near the St.
                 Augustine inlet. However, it is not part of the Intracoastal Waterway.


                 The majority of the watersheds in this basin are drained by relatively small creeks into the lagoons. In the
                 northern basin, the Moultrie Creek drainage area and the Pcllicer Creek watershed are dominated by
                 forest land, but also have significant amounts of wetlands. The Tomoka River, in the southern portion of
                 the basin, drains wetlands. Both sub-basins have some agricultural drainage through inland canals.
                 Urban areas in the basin include St. Augustine, Ormond Beach, Daytona Beach and several other smaller



                                                                                                                              31









                  communities. Increased development in certain areas, such as: Palm Coast and Palm Valley in Ponte
                  Vedra, could adversely influence the Intercoastal Waterway and their respective areas.

                  A basin assessment of the East Coast Basin performed by district personnel indicated major water quality
                  problems in the Halifax River between Ormond Beach and Daytona Beach. There are elevated nutrient
                  concentrations and excessive turbidity in the area due to urban runoff and effluent from several municipal
                  WWTPs which have a combined discharge of about 30 MGD. There is suspected oil and grease
                  contammation 'in this area from the numerous auto service businesses along the river. Maintenance
                  dredging of the ICWW resuspends sediments and their associated nutrients, metals and oxygen
                  demanding substances. Finally, there are six causeway bridges which act as physical obstructions and
                  serve to compartmentalize the pollution and decrease circulation. A wasteload allocation study of the
                  Halifax River based on water quality data and tidal measurements recommended that advanced
                  wastewater treatment was necessary in order to prevent further degradation. The WWT?s are in the
                  process of, or have agreed to upgrade treatment levels and make further investigation into re-use
                  possibilities. Additionally, the Port Orange Causeway has been modified to allow for better circulation of
                  the southern Halifax.


                  Other areas in the basin winch show borderline good-fhir water quality are Spruce Creek and Tomoka
                  River. Both receive agricultural runoff, and the lower Tomoka also gets airport runoff. Attempts are
                  under way in these areas to improve the quality of stonuwater runoff through the use of treatment basins.
                  A DEP basin assessment found both creeks to have a relatively good biological community. The Nonpoint
                  Source Assessment indicates the Moultrie Creek and Pellicer Creek, in the northern portion of the basin,
                  are degraded by construction and urban runoff


                  The ICWW from Jacksonville Beach to south of Flagler Beach was the subject of a past basin assessment.
                  The Matanzas River around St. Augustine is affected by urban runoff, WWTPs, port activities. ne river
                  exhibits elevated nutrient concentrations and some metals contamination problems. The Matanzas, and
                  Tolomato Rivers are classified for shellfish harvesting, but are closed to shellfishing.

                                                                                                                                 38










                   Ecolo,gical Characterization


                   IUs coastal lowlands basin in Florida's Big Bend area includes several small river systems: the Econfina
                   River, the Fenholloway River, Spring Warrior Creek, the Steinhatchee River, and Sanders Creek. These
                   small rivers drain swampy lowlands and empty into salt marsh estuaries at the Gulf of Mexico.

                   Some of these rivers are characterized as acidic blackwatem flowing over a sandy and limestone substrate,
                   but a number of these receive groundwater input. Some karst features are, evident such as limestone
                   outcroppirigs and some small,springs. Both the Steinhatchee and Econfina Rivers are captured by
                   sinkholes at normal to low flows. The Fenholloway is partially captured by sinks as arc some of the
                   smaller tributaries.


                   The basins uplands are almost entirely in silviculture. There are extensive swampy wetlands around the
                   river's drainage areas, and the basin!s coastal margins are belted by salt, marshes. There is little urban
                   development in the basm. A few small hunting and fishing communities have developed near the mouth
                   of the rivers.


                   Apthro zenic Impacts


                   The Fenholloway River is the only waterbody in the state with a Class V water quality classification
                   (Navigation, Utility and Industrial use). It has been severely affected by the discharge from a paper mill
                   which makes up the entirety of the river's flow in drier times. The large quantities of water withdrawn by
                   the paper mill act to lower the ground water table thus decreasing the amount of base flow that the river
                   would normally receive. Water quality is poor with low DO, high BOD, high conductivity, and other
                   symptoms of high organic loading A Use Attainability Analysis is now being conducted to determine if
                   the Class V water quality classification can be upgraded.to a Class Ill.

                   FDEP's groundwater investigations near the Fenholloway River have found contamination in wells linked
                   to upstream pulp mill discharge. All other rivers in the basin have good water quality although somewhat
                   low in DO and pH due to the swampy drainage. The estuaries at their mouths support a healthy biological
                   community with sport and commercial fisheries-. Septic tank pollution is a concern in the area because
                   most of the basin's soils are poorly drained and thus incompatiblewith, proper septic tank functions.

                   The most recent sampling by FDEP indicates that fecal bacteria counts were elevated at the mouth of
                   Sanders Creek. The City of Cross City municipal WWTP discharges to the swamp that drams to this
                   crock but no direct relation has been proven. Also nutrient and, chlorophyll a levels are somewhat
                   elevated in the upper reaches of Spring Warrior and Weaver Warrior Creeks.

                   Silviculture is a potential source of pollution and has been blamed by local residents for alterations of river
                   characteristics leading to declining fish populations and excessive sedimentation. Compliance and
                   application of silvicultural Best Management Practices has been good. These practices were shown in
                   other studies to alleviate sedimentation and erosion to. surface waters. Also ditching and channeling
                   waters in the forested areas may lead to hydrologic disruptions in the estuary, i.e., increased fi-eshwater
                   runoff during rainy times and decreased fresh water release in drier times. Hydrological models
                   comparing the periods of 1952-53 and 1988 showed a 38.6% increase in peak flows.


                   The Fenholloway, Econfina, and Steinhatchee Rivers have been monitored since 1989 as part of the
                   SRWND's SWIM program.

                  Ecological Characterizatio


                  The Nassau River Basin drains 430 square miles of predominant    ly forest and wetlands. There are 55
                  stream miles in the basin and approximately 10 square miles of estuary (including South Amelia River,
                  the mouth of Nassau River, Sisters Creek and Ft. George River). The blackwater Nassau River's main
                  tributaries (Mills, Alligator and Thomas Creeks) flow slowly in meanders through coastal lowlands. Land
                  use is mostly silviculture, but there are also dairy operations and increasing urbanization.


                  Anthropogenic Impacts


                  Historically, the Nassau River Basin has limited STORET data, but has previously shown mostly good
                  water quality. However, the Nonpoint Source Assessment indicates that the Mills-Alligator Creek
                  drainage is moderately impaired from dairies, septic tanks, and urban activities. The town of Callahan
                  WWTP discharges to Alligator Creek which discharges to Mill Creek. Mills Creek exhibits poor water
                  quality and affccts some downstream stations. The Thomas Creek drainage is suspected of having
                  problems from similar sources, The Anheuser Busch 50d Farm discharges to Thomas Creek.

                  The Amelia Islands reach shows minor problems with elevated BOD, turbidity and phosphorus
                  concentrations which could be attributed to development on the islands and/or the effects of a pulp mill
                  discharge to the Amelia River in St. Marys Basin. Sisters Creek and Ft. George River estuaries exhibit
                  good water quality.

                 Ecological Characterization



                 The Santa Fe River Basin drains 1,390 square miles of mixed land uses in north central Florida. The
                 Santa Fe River has its source in hardwood swamps surrounding and draining Santa Fe/Little Santa Fe
                 Lake and other lakes and swamps nearby apparent, with sinking streams in the region of the Cody Scarp.
                 In this upper part of the basin, it is a sand bottomed creek with blackwater characteristics. In the middle
                 part of the basin, the Santa Fe is joined by two of its main tributaries, New River and Olustee River, both
                 blackwater rivers draining mostly forest, agricultural, pasture, and swamp lands. Further downstream
                 karst features become more apparent. Downstream of its confluence with Olustee River, the Santa Fe
                 disappears into a sinkhole at O'Leno State Park at the toe of the Cody Scarp. The river rises after
                 traveling about 3 miles underground where it receives an average additional flow of 211 cfs of
                 groundwater. From here to its confluence with the Suwannee River, many springs add to the flow.
                 Notably, the Ichctucknee River contributes about 400 cfs of crystal clear spring water to the Santa Fe,
                 bringing its flow to about 2,000 cfs. Water quality on the lower Santa Fe is characterized by higher pH,
                 higher conductivity and alkalinity, and increased water clarity. The river as a whole supports a diverse
                 biological community.


                 There are increasing amounts of low density residential land use in the basin. The Santa Fe and
                 Ichetucknee Rivers are both popular for recreation. There are dairy operation in the lower Santa
                 Fe/lchetucknee River area.


                 Apthro
                       Mgenic Impacts


                 The Santa Fe River has been declared an Outstanding Florida Water. Most of the reaches and lakes in the
                 basin that have been sampled meet their designated uses. Because much of this river is naturally low in
                 pH and/or dissolved oxygen due to swamp land drainage and spring flow, the calculation of the WQI is
                 more complicated. However, it is noted from the basin water quality index table that several reaches have
                 minor problems with nutrients and bacteria. These Teaches drain mostly swamp lands so the high values
                 appear to be of natural origin or perhaps some agricultural runoff.


                 There are a few specific problem areas in the basin due primarily to WWTP effluent. Alligator Lake has
                 been partially diked and drained for farmland. It receives Lake City stormwater and, in the past,
                 discharge from the Lake City WWTP which was diverted in the fall of 1987. It has nutrient, algal bloom,
                 aquatic weed and fish kill problems. During low water conditions, the North Lobe of the lake is drained
                 by a sinkhole. Lake Rowell demonstrates a slight cutrophication problem. Some enrichment of heavy
                 metals is evident in the lake's sediment. The City of Starke WWTP discharges to Alligator Creek which
                 drains into the lake. Alligator Creek is impacted by WWTP discharge and possible titanium mining in
                 the area. Santa Fe Lake exhibits good water quality, but with increasing levels of nitrogen. It is
                 connected by the Waldo Canal to Lake Alto. It is also threatened by the City of Melrose storm drainage
                 and development along the shoreline.


                 Portions of New River exhibit elevated bacteria, nutrient and turbidity values. It receives discharge from
                 the Raiford WWTP and the PRIDE facility, and indirectly from the Lake Butler WWTP. A waste load
                 allocation has been developed for New River because of these sources. There is also a considerable
                 amount of cattle farming in the headwaters that may account for some of the problem values. Conditions
                 in the Santa, Fe below New River reflect the lower water quality of the New River. Local experts also
                 indicate that Olustee Creek has poorer water quality than the Santa Fe. At present, the SRWMI:) is


                                                                                                                                    52










                  producing a detailed water quality and aquatic biological assessment of the New River to better define the
                  impacts or WWTPs,


                  The final area of concern is the lower Santa Fe near its confluence with the Suwannee River. There are
                  many dairy farms in the area, and while there is very little surface water drainage from the farms, there is
                  a high potential for ground water contamination. Initial data from the Suwannee River dairy study
                  indicate existing waste management practices at the dairies have the potential to contaminate ground
                  water with elevated nitrates. Based on this data, DEP is requiring all new dairies in the Suwannee River
                  Basin to apply for industrial wastewater permits and provide reasonable assurances that surface water and
                  ground water will be protected. In 199 1, data indicate elevated nitrates in ground water near Ft. VVhite
                  and the Ichetucknee River. The Department is currently conducting a sampling investigation to assess the
                  nitrate levels in the area.


                  Because there are so many springs and underground conduits of water flow, any threat to the ground water
                  is also very important to surface water quality. A pilot study was performed in 1991 to determine the
                  sources of water to springs feeding the Ichetucknee River. Additional studies are proposed to better define
                  the sources in an effort to ensure protection of the spring water qualiti.

                  The Santa Fe Basin has been designated a SVVTM priority water by the SRWMD. Under the SWIM
                  program a water quality and biological monitoring program of the basin was begun in 1989.

                      * Since 1987 the City of Jacksonville has reduced 43% of the small
                        package wastewater treatment plants with regionalization to larger
                        treatment facilities.
                      * Since 1988, through the efforts of the SWIM Program of the Duval County
                        Health Unit, 1038 failing septic tank systems were located and
                        repaired by permit. An additional 1435 failing septic systems have
                        been referred to the City of Jacksonville's Public Utilities Depart-
                        ment for regional connection through the Superfund Septic Tank Phase
                        Out Program.
                      * In 1992, Seminole Kraft, a manufacture of unbleached paper, recon-
                        figured the mill to produce linerboard from 100% recycled fiber
                        reducing their wastewater flow to an average of 10 MGD, a reduction
                        of approximately 75%.

                 Ecological Characterization


                 The St. Johns River is Florida's longest river (300 miles) and flows northward from its origins west of Ft.
                 Pierce, to its mouth, near Jacksonville. It is extremely slow moving with a drop of less than 30 feet over
                 its entire length. The lower St. Johns River is defined as the section between the Oklawaha River
                 (entering at about 160 cfs) and the Atlantic Ocean. This segment of the river is essentially an elongated
                 lagoon, having a low gradient and narrow floodplain. The river averages more than two miles in width
                 downstream of Palatka (in some places it exceeds three miles) and contains numerous tributary streams
                 and embayments.


                   The entire lower St. Johns River is subject to tidal influence. The low gradient in the St. Johns River
                 combined with the effects of low flow, tides, and wind direction result in short-term reverse flows.
                 Although these reverse flows may continue for several days, there is a net downstream flow approximately
                 75% of the time. The total average flow of the river is estimated at 7000 cfs. Development impacts along
                 the river vary by area. The reach between Palatka and Green Cove Springs has experienced only modest
                 development as homesites, but below Doctors Lake to the Trout River, the river is almost entirely lined
                 with homes, buildings, marinas and docks. In contrast, there are few docks and homes from Trout River
                 to Mayport. From downtown Jacksonville to the Atlantic Ocean, the river is dredged and maintained by
                 the Corps of Engineers for deepwater navigation (a 12 foot deep channel is maintained by Corps of
                 Engineers from Jacksonville to Lake George). Also there are several bridge crossings: seven in Duval
                 County; one in Green Cove Springs; and one in Palatka.


                 The tributary systems entering the St. Johns are generally blackwater in nature and drain mostly low pine
                 lands. Downstream of Doctors Lake, on the west bank and in the Julington Creek area, most of the
                 tributaries have considerable urban development, both residential and, near Jacksonville, industrial.



                                                                                                                                       59











                  An1hropogenic Impacts


                  This assessment of the lower St. Johns River begins in the southern portion of the basin, and then moves
                  northward to the Duval County portion of the basin. Water quality of the southern portion of the lower St.
                  Johns River is judged to be good, especially at its confluence with the Oklawaha, but generally degrades
                  downstream. There is an increase in nonpoint source nutrient discharge resulting from runoff from
                  row-crop agriculture. The Palatka area also provides urban runoff and septic tank leachate.


                  There are problems in most of the tributary stream systems of the river. The first tributary system in the
                  southern basin is Haw Creek/Crescent Lake/Dunns Creek. It has acidic colored water attributable to its
                  swampy drainage area and DO and nutrient problems attributable to agricultural runoff, septic tariks and
                  WWTP effluents. Point sources in this area include the Crescent City WWTP discharging to Crescent
                  Lake and the City of Bunnell WWTP discharging to Haw Creek. Crescent Lake is eutrophic and a 1975
                  EPA study estimated that about half the nutrient load to the lake came from Haw Creek. Recent estimates
                  of nutrient loading identified agricultural runoff as the main source of nutrient loads. A second study of
                  the lakeby DEP's Biology Section was performed in June, 1990. That study found depressed
                  macroinvertebrate diversities, significant blue-green algal blooms, ana high algal growth potential and
                  chlorophyll a concentrations in Crescent Lake, Bull Creek Canal, and Dead Lake. Depressed oxygen
                  levels, below State water quality standards, were encountered in Dead and Crescent Lakes. In addition,
                  elevated levels of zinc, copper, and cadniium were found in sediments from the vicinity of potato and
                  cabbage fanning operations. The Wce is used for fishing and blue crab trapping, though few people use
                  the lake for swimming. Lake Disston is threatened by land clearing operations close to the shoreline and
                  row-crop farming, but is still enjoyed for both fishing and swimming.


                  The Rice Creek tributary system, located just north of Palatka, arises from a pine flatwood/mesic
                  hammock system. The creek's discharge has low DO and pH. Elevated bacteria counts in the vicinity of
                  the Etonia Creek watershed may be accounted for by dairy farms. The lower portion of Rice Creek
                  receives a large volume of effluent from a paper mill (Georgia-Pacific) which has very low DO values and
                  high nutrient, BOD and color values. The macroinvertebrate communities in the creek exhibit a low
                  diversity with only a few highly tolerant species. Georgia-Pacific uses 'a process of supersaturating their
                  effluent with oxygen before discharging to Rice Creek and in the vicinity of the discharge high values of
                  DO are encountered. In the past, a short distance downstream the low DO problem reoccurred. More
                  recent data indicate that the problem has abated. Rice Creek degrades the St. Johns River both upstream
                  and downstream of its confluence. Simms Creek, Boggy Branch, Greens Creek, and Clarkes Creek have
                  sporadic turbidity problems due to spills from upstream titanium mining operations.


                  The next problem area in the lower St. Johns River basin is Trout Creek. For a few years in the
                  mid- I 980s, it received very poorly treated effluent from the Homer Smith scallop processing plant. The
                  plant has ceased operation in 1986, which has improved water quality. St. Johns County acquired the site
                  and turned it into a park in 1992 with a boat ramp and picnic area. There is a nonpoint source threat from
                  development in the upper Trout Creek drainage.

                  The Black Creek/Peters Creek tributary system has fairly good water quality but is threatened by urban
                  and agricultural runoff. Nutrient and BOD problems occur, probably caused by agricultural and dairy
                  runoff. These problems are more evident in Peters Creek, labeled as seriously impaired by the Nonpoint
                  Source Assessment. The area is undergoing rapid development which is affecting the stream system with
                  increased domestic wastewater discharge, septic tank and stormwater runoff.




                                                                                                                                         60








                  Julington and Durbin Creeks are undergoing some of the most rapid development in.the basin. Increased
                  siltation and an associated decrease in fish breeding ground and fish populations have been documented in
                  these sub-basins. Wasteload allocations are proposed for the numerous small WWTPs in the Julington
                  Creek and Durbin Creek area. Both of these tributary systems drain low-gradient swampy lands into a
                  large floodplain. Poorly drained upland areas are scattered throughout the drainage. Thus, continued
                  development frequently involves wetland disruption. It is estimated that about one-half of the wetlands in
                  the Julington Creek drainage have been lost in the last 20 years. The eastern riverbank downstream of
                  this drainage (area of Mandarin and Goodbys) is severely altered and degraded by marinas and near-shorp
                  development.

                  Doctors Lake is highly eutrophic as a result of excessive nutrient loading from historic WWTP discharge,
                  septic tank leachate and urban runoff. New golf courses, residential developments and shopping centers
                  are being built in the Doctor's Lake watershed. The lake's poor circulation and limited hydraulic flushing
                  further compound water quality problems. The effluents from the Orange Park plant and several other
                  WWTPs were diverted from the lake in the late seventies and routed to the St. Johns River. The lake still
                  exhibits eutrophication problems (algal blooms, fish kills, turbidity) attributed to urban runoff, and has
                  been closed to swimming.


                  The most concentrated area of water quality problems in the lower St. Johns River is found in the Duval
                  County portion of the basin. This section of the basin is one of several large industrialized regions in the
                  State and one of the largest residential centers as well. Duval County has approximately 300 permitted
                  point source dischargers. A wide range of water quality problems are found including dissolved oxygen,
                  nutrient, bacteria and toxics. Also an outbreak of Ulcerative Disease Syndrome (UDS) in a variety of fish
                  species has persisted in the Lower St. Johns River for the past decade. Studies were unable to determine
                  whether the outbreaks of disease were related to pollution levels. A Lower St. Johns River Water Quality
                  Review prepared by DEP in 1986 presented a overview of the river's status and made recommendations
                  for controlling domestic and industrial effluents and stormwater runoff. That report, as well as the
                  findings of other studies and experts on the basin, indicated that the tributaries were more heavily polluted
                  than the river itself, particularly in sediment quality. A brief review of the problem areas is presented
                  below. Starting in the southern portion of Duval County, one of the notable problem areas is the Cedar
                  River/Wills Branch/Ortega River system. Cedar River has the worst water quality in the area with
                  frequent fish kills. The area receives discharges from wire and chemical industries as well as numerous
                  wastewater treatment package plants. This tributary system appears to have a negative impact on the
                  quality of the St. Johns River itself. However, just north of this segment (at the horizontal "bend" in the
                  river), the St. Johns also receives drainage from two severely polluted urban creeks (not shown on map)
                  and the Jacksonville shipyards. Adjacent to this reach are Strawberry and Pottsburg Creeks which also
                  exhibit poor water quality caused by pollution loads from WWTPs and stormwater runoff.

                  The "bend" area is probably the most polluted and developed portion of the river. Both banks are almost
                  completely sea-walled and lined with industries or downtown development. It appears that the shipyard,
                  which previously conducted sandblasting and painting directly adjacent to the river, is closing down.
                  While the shipyard is being closed down there still is much sandblasting and painting at the docks. Two
                  other major sources are Jacksonville's regional WWTP (Buckman Street WWTP) discharging 52 MGD,
                  and Jefferson Smurfit (formerly Alton Box and Packaging Corporation) with a total d    ischarge of 14 MGD.
                  The Buckman plant, which generally provides good treatment, also accepts some industrial wastes which
                  cause occasional upsets in the treatment process.


                  The Ribault River, lower Trout River and Moncrief Creek, probably the second worst tributary system
                  after Cedar River, also empty into the St. Johns River a few miles north of this area. Downstream from                61











                 ,he conflucncc olTroul River, he St. Johns River receives treated paper mill wastewater effluent (Kraft
                 Paper Company at 20 MGD). Discharges ftom Broward River and Dunn Creek further affect the river.
                 These tributaries, although not as severely degraded as the previously mentioned systems, exhibit low DO
                 values and high concentrations of nutrients and BOD from domestic and industrial point sources and
                 some dairy operations. From Dunn Creek to the mouth there is more flushing and dilution from the tides
                 and more vegetated banks and marshes. Commercial shrimpers work the St. Johns between May Port and
                 the Matthews Bridge, seaward of downtown Jacksonville. Only recreational shrimping occurs between
                 Jacksonville and Lake George-


                 In summary, the southern portion of the Lower St. Johns Basin generally exhibits good to fair water
                 quality. With the exception of one tributary system with poor water quality due to a point source, the
                 major sources of pollution are runoff from rangelands and construction sites. On the contrary, the Duval
                 County portion of the basin generally has poor water quality. Both domestic and industrial point sources
                 are major contributors to the problem as well as urban stormwater and septic tanks. For several years it
                 has been recognized that the tributary systems in this area are seriously degraded. However, more recently
                 there has been growing concern over the river itself. Benthic biological data indicate poor diversities and
                 low density. Water quality trends for most of the river reaches indicat@ degradation problems. However,
                 there is improvement of the river's water quality near its mouth due to the flushing effects of the tides.


                 Duval County continues to grow and several of the WWTPs discharging to the St. Johns are considering
                 expansion. However, there are active efforts to regionalize the county, and centralize wastewater
                 treatment into larger facilities in order to decrease or remove small facilities and septic tank drainage
                 from the tributaries. Duval County has a $4,000,000 revolving trust fund which is used to purchase
                 private package plants and connect them to the county's regional WWTP.

                 The 1987 Florida Legislature passed the Surface Water Improvement and Management (SWIM) Act
                 which will provide funds to the State's Water Management Districts to restore or preserve some of the
                 critically threatened water bodies. Key aspects of the SWIM Plan submitted by the St. Johns River Water
                 Management District area:


                   1. a Master Stormwater Plan being developed by the City of Jacksonville and the water management
                 district;
                   2. increased enforcement of regulations regarding septic tanks, package plants, etc. (through SWIM
                 funded contracts with Duval, St. Johns, Clay and Putnam Counties);
                   3. studies and programs designed to reduce nutrient input from agricultural activities in St. Johns,
                 Flagler and Putnam Counties;
                   4. more comprehensive monitoring of the river and tributaries (as a system); and
                   5. technical assistance to local governments.
                   6. monitoring to determine phytoplankton species and productivity, benthic fauna and toxic substance
                 contamination, and demersal fish assemblages to determine assimilative capacity and food chain
                 dynamics.

                      There was a 305b meeting held in the Northeast District DEP office on July 18, 1994. Part of the
                      objective of this meeting was to designate reaches on the lower St. Johns River and to determine what
                      indices should be used for each reach. Attached is the location and the justification for the indices used for
                      each reach. The following indices are used in the attachment.

                              The U.S. House passed and sent to President Bush legislation authorizing
                              the National Park Service to study the St. Marys River to determine
                              if sections should be protected as part of the National Wild and
                              Scenic River System. The Final Draft of the study was published for
                              public comment in December 1993. The study found some portions of
                              the river eligible and suitable for the designation. It includes
                              recommendations on who to manage the protected areas.

                          ---------------------------------------------------------------------------


                      Ecological Characterization


                      The St. Marys River has its origins in the Okefenokee and associated swamps in the western portion of the
                      basin. The average flow of the river is about 1,200 cfs. This remote blackwater stream forms the
                      northeast border between Florida and Georgia. There is little development in the upper basin. Where
                      accessible, land use is primarily silviculture. A small urban and agricultural area exists in the South
                      Prong drainage. The lower portion of the St. Marys River is tidally influenced and reverse flows occur


                                                                                                                                                             80









                daily. Amelia River forms the estuarine portion of the basin and has a drainage area of approximately 5
                square miles.


                AnthropMenic Impacts


                The St. Marys River with its extensive marsh system generally has excellent water quality. There are
                three areas of concern in the basin: the South Prong, Little St. Marys, and Amelia River. The basin,
                upstream of Boulogue, is generally characterized by naturally high color, low pH and low DO.

                The South Prong, in the past, has shown minor problems with high bacteria and nutrient concentrations,
                possibly due to agricultural impacts and to the effluents from the Macclenny WWTP and the Northeast
                Florida State Hospital WWTP. Both effluents discharge to Turkey Creek, a tributary of the South Prong.


                Finally, the Amelia River estuary has historically exhibited fair water quality with DO, water clarity and
                nutrient problems. The Fernandina Beach WWTP discharges directly to the Amelia River. Two Florida,
                one Georgia pulp paper mills, and urban runoff from rapidly developing Fernandina Beach and Amelia
                Island also affect the water quality. More recent data indicates the DO problem has been reduced. Also,
                the City of St. Marys on the Georgia border is growing rapidly, related to the Kings Bay Naval Base and
                the paper industry. A site specific alternative criterion of 3.2 mg/I dissolved oxygen has been issued for
                the Amelia River in the vicinity of the ITT Rayonnier (paper mill) discharge point during certain tidal
                flows. Additionally, high ammonia-ammonium concentrations are being found in the Fernandina Beach

                area.

                    * A 10-20 year flood occurred on the Suwannee River during the late
                      winter of 1991.
                    * The Dixie County Board of County Commissioners passed a county ordinance,
                      creating a Water and Sewer District for the Town of Suwannee in November,
                      1992. In doing so the town is moving toward centralized WWTP and removal
                      of septic tanks.
                    * A major winter storm, known as the Storm of the Century, impacted the
                      Suwannee River late winter of 1993.
                    * DER released PRFT monies to Suwannee River Water Management District in
                      November 1991 for the restoration of Ruth Springs, Royal Springs and the
                      tidal shore line of the Town of Suwannee. Restorations were completed in
                      August 1993.

                 Ecological Characterization


                 The Suwannee River, with an average flow of 11,000 cfs, is one of Florida's largest, relatively unspoiled
                 rivers, and one of its most treasured. From its headwaters in the Okeefenokee Swamp, it travels 245 miles
                 to the Gulf of Mexico. The Lower Suwannee River Basin begins at the junction of the Withlacoochee
                 River where the Suwannee River renews its southerly course. From the headwaters, the downstream
                 increase in flow reflects not only the larger drainage area but also a major contribution of ground water
                 from the Floridan Aquifer through springs along the river's course. The lower river also receives flow
                 from two major tributaries: the Withlacoochee River with a discharge of 1,600 cfs, and the Santa Fe River
                 ,writh an average flow of 2,000 cfs.


                 Most of the Suwannee River flows through excessively well-drained soils, thus there is relatively little
                 overland drainage and few tributaries. Instead, water percolates through the soil and into the ground
                 water. Conduits of the karst terrain account for the numerous springs. The springs can be thought of as
                 tributaries of exceptionally good water quality, however, when the river is under flood conditions, it covers
                 the springs and a reverse flow occurs. The springs drain the river water which causes impact to the
                 groundwater.


                 Because of its drainage characteristics, the land may not be well suited for agriculture and dairy
                 operations. There is concern that the impacts of dairies and other high intensity agricultimal operations
                 will degrade ground water. Monitoring wells, as part of the DEP/SRWMD VISA Network, are being
                 sampled. The basin is sparsely populated and there are only a few communities adj acent to the river.
                 Below Fanning Springs, the river passes into the lower coastal areas which are primarily forested swamp
                 land where silviculture is the major land use. The Town of Suwannee lies next to the estuary. Manatees
                 are found in the lower reaches of the Suwannee River.


                 Anthr-onge-nic Impacts


                 The Suwannee River has been designated an Outstanding Florida Water and is considered to be one of the
                 State's treasures. Water quality is generally good in all reaches of the lower Suwannee River. Phosphorus
                 is contributed by mining operations, which are located in the upper Suwannee River basin. Over the past
                 decade total phosphorus concentrations have been declining. In addition, Gold Kist, Inc., poultry
                 processing plant discharges below the confluence of the Withlacoochee River. There are a few other
                 pollution sources in the basin such as septic tanks and dairies.

                 The Withlacoochee basin has several pollution problems. It receives a considerable sediment, nutrient,
                 and possibly pesticide loading from agricultural runoff. Additionally, several WWTPs discharge to the
                 Withlacoochee in Georgia. The Withlacoochee also receives effluent from a pulp mill in Georgia via
                 Jumping Gully Creek. Eutrophication, however, is not a severe problem in the Suwannee because of the
                 rapid flushing of the system and the spring inflow to the river. The effects of this enrichment on the
                 receiving estuary, Suwannee Sound, have not been determined. The lower river is threatened by housing
                 developments within the floodplain. The Town of Suwannee relies entirely on septic tanks for wastewater
                 treatment. A 1991 HRS study of on-site septic tanks found that most of the septic tank systems were
                 inadequate. Additionally, the town is built on a low lying, swampy area connected with a network of
                 drainage canals. A past study by the Northeast DEP District indicated that the Town had an extensive
                 bacteriological impact on the area due to chronic wastewater leachate problems. Nearby shellfishing areas
                 are frequently closed due to high bacteria values. The Town recently created a Water and Sewer District
                 which will facilitate its efforts to obtain a centralized wastewater treatment plant.

                 Ecological Characterization


                 The Suwannee River is one of Florida's least developed and least polluted large rivers, and as such, is. one
                 of its most treasured resources. The upper Suwannee River basin drains portions of Florida and Georgia,
                 encompassing a total area of 9,950 square miles. Approximately 926 miles of the drainage area are
                 located in north central Florida; the remainder of the watershed drains parts of south central. Georgia.
                 Traveling a total distance of 265 miles from- the headwaters, the Suwannee River ultimately discharges
                 into the Gulf of Mexico. Below White Springs, the Suwannee River and its principal tributaries (Alapaha
                 River, Withlacoochee River, and Santa Fe River) are fast-flowing streams with deep channels underlain
                 by karst topography and characterized by numerous sinks and springs.


                 Headwaters of the upper Suwannee River near Fargo, Georgia, are formed by the convergence of
                 numerous channels flowing from the southwest comer of the Okeefenokee Swamp. Consequently, the
                 river at this point is very darkly stained and acidic. Flow measured below the swamp averages 1,800 cfs.
                 Average daily flow 30 miles above the mouth of the Suwannee is 11,000 cfs, making. it the second largest
                 (by flow) river in Florida. The southward flowing river turns sharply westward near White Springs,
                 Florida, near the Cody Scarp. The Alapaha and Withlacoochee Rivers originate in Georgia and join the
                 Suwannee River as it renews its southward course. The average discharge rate of the Alapaha River and
                 the Withlacoochee is 1,600 cfs/each. At low flow the Alapaha River is captured by a sinkhole. It is
                 believed to discharge to the Suwannee River through Alapaha Rise Spring. This area also receives
                 substantial flow from the Floridan Aquifer through numerous springs.

                 Land use in the upper Suwannee River basin is primarily silviculture and agriculture. There is also
                 substantial drainage of swamp lands. The basin is sparsely populated and White Springs is the only
                 community actually located on the river. Watersheds and headwaters of Hunter Creek, Roaring Creek,
                 Four-mile Branch, Swift Creek, and Camp Branch are currently being mined for phosphates.

                 The Suwannee River is an Outstanding Florida Water and sections of the river have very good water
                 quality. The Florida portion of the Upper Suwannee River Basin is surrounded by the Alapaha River
                 Basin to the west, the Lower Suwannee River Basin and the Santa Fe River Basin to the south, and the St
                 Mary's River Basin to the east. In generally exhibits low pH, high color and low conductivity. These
                 conditions are typical of waters draining swampland.


                 A large number of point source discharges to tributaries of the river arc located in Georgia. These include
                 municipal and industrial WVTP's, paper mill effluent, and effluent from aluminum product
                 manufacturing. The river receives a large loading of phosphates, organic nitrogen, sulfates, and fluorides
                 at Swift Creek from Occidental Chemical Company. The elevated nutrient values are evident downstream

                                                                                                                                        95










                until they become diluted from flows of the Withlacoochee and Alapaha Rivers and several springs.
                Hunter Creek, which also receives Occidcntal effluent, exhibits high phosphorus values. Coliform levels
                are high in Roaring Creek, Swift Creek, Hunters Creek and the Suwannee River area above and below the
                confluence of Swift Creek. The original stream channel of Roaring Creek is being mined for phosphates.
                A new channel has been created. Occidental has been permitted a new discharge point at Camp Branch.
                The discharge consists of excess water from rainfall runoff in the watershed and from dewatering
                operations during mining. The excess water is routed to previously mined pits or reclaimed areas for
                clarification before being discharged to Camp Branch.

                A detailed study of the entire Suwannee River was published by the Department of Environmental
                Regulation in 1985. It emphasized the marked difference in the upper and lower rivers, predominantly
                caused by a drastic pH change (from about 4 to 7) in the area of the Withlacoochee/Alapaha Rivers
                resulting from the inflow of the springs. Aside from the water quality changes associated with the ground
                water inflow, mining and phosphate beneficiation operations had the greatest impact on water quality.
                The upper Suwannee River is a SWIM priority water. Since 1989, an extensive surface water quality and
                biological monitoring program of the river and its tributaries has been performed by the SRWMD and
                their contractors. HRS is conducting an assessment of on-site septic tarl systems compliance within the
                floodplain of the river. Finally, a water quality study conducted by the University of Florida defined
                ambient water quality. This study will be useful in the future determination of water quality for both
                existing and future discharges to the river.


                Additional threats to the upper river are construction runoff, shoreline modification and septic tank
                seepage from residential development within the floodplain. However, at this point; the river is sparsely
                developed. A proposal for a large campground and trailer park was recently withdrawn. Agricultural
                land use may threaten springs within the river basin. Water quality threats from the Withlacoochee River
                are covered in the Lower Suwannee Basin.

                   In the News

                   * Land use in Waccasassa Flats is an issue between Gilchrist County
                     residents and the County Commission. The most recent comprehensive
                     plan for the county allows one shed per 80 acres or one house per
                     160 acres. Some local residents want no development.
                   * The Town of Cedar Key has applied for a Wastewater Treatment Plant
                     permit, which is expected to be issued in December, 1993.

                   Ecological Characterization

                   The Waccasassa River Basin drains 936 square miles of forest land and wetland between the Suwannee
                   and South Withlacoochee Rivers. The river is 29 miles long and has an average flow of approximately
                   300 cfs. Blue Spring, at the headwaters, and several other small springs, supply ground water to the river.
                   However, much of its flow is swamp and woodland drainage, thus giving it the typical blackwater color.
                   The river empties into the Gulf of Mexico via a large coastal Juncus marsh. There are no major urban
                   areas in the basin, however, one of the barrier islands, Cedar Key, is a developed recreational and
                   historical site.

                       Reclassification of Jumping Gully Creek as a Class III Waterbody
                       in 1991.
                       Packing Corporation of America has entered into a Consent Order with
                       DEP, which requires it to conduct research, feasibility and
                       engineering studies to meet class III standards in Jumping Gully
                       Creek. Studies are under review.
                      ---------------------------------------------------------------------------


                 Ecological Characterization


                 The Withlacoochee River basin originates in Georgia and terminates in the Suwannee River about 20
                 miles south of the Georgia-Florida border. The basin is 1,510 square miles in area and has 338 miles of
                 river reach, but only 28 miles of river reach are located in Florida. The Withlacoochee River has a flow of
                 1,600 cfs before it enters the Suwannee River. The river is highly colored, but has alluvial characteristics
                 as well. It carries more suspended sediments than most north central Florida streams. The river also
                 receives flow ftorn the Floridan Aquifer through several springs along its course in Florida. Blue Springs,
                 the largest, is located about 10 miles upstream of the confluence with the Suwannee River. The major
                 tributary of the Withlacoochee in Florida is Jumping Gully Creek near the Florida-Georgia border. The
                 Florida portion of the basin is about half forest land and half agriculture. However, much of the upper
                 basin, in Georgia, is in agriculture.


                 Anthropo-genic Impacts




                                                                                                                                  109









                  The River receives several point discharges before it enters Florida from a total of six domestic wastewater
                  and four industrial wastewater point sources. The industrial dischargers are involved in plating and
                  polishing alun-iinum manufacturing. In Florida, the Withlacoochee River exhibits borderline good/fair
                  water quality depending on flow. During the rainy season, the river is characterized by higher than
                  average sediment load for Florida rivers due to agriculture being the dominant land use in the basin.
                  When it's dry, the relatively greater spring flow and less runoff have a beneficial effect on water quality.

                  Another major pollution source to the river is a paper mill located on Jumping Gully Creek that
                  discharges about 12 MGD of high color and BOD effluent. The effluent discharges through an
                  impoundment outfall. The Environmental Regulation Commission decided to reclassify Jumping Gully
                  Creek as a Class III water.
