              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.

              *   Regional Reports - 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).
              0   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.
              0   ARC/INFO Water Ouality 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.
              0   New Nonpoint Source Qualitative 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. Historic data were used to
                  assess waterbodies only when there was no current data available.












                                              ACKNOWLEDGMENTS


            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.


            Many individuals in the District Offices reviewed the report on their sections of the State. These
            individuals include Rick Bradburn, Glenn Butts, Donald Ray, and Tone Touart-Rohlke in the
            Northwest District; Cathy Krestalude, Ernie Frey, Lee Banks, Angela Halfacre, and Jim Wright of
            the Northeast District ; Eric Pluchino and Dave Herbster of the Central District; Paul Wierzbicki,
            Herb Zebuth, and John Moulton of the Southeast District; Gordon Romeis of the South District,
            and Pat Fricano of the Southwest District. Sid Flannery of the Southwest Florida Water
            Management District also reviewed the report for his area.

            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.

                                          EXECUTIVE SUMMARY/OVERVIEW


             The 305(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 Quality Assessment Main Report submitted to
             EPA.


             The assessment required analysis of the available STORET 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) assessment also 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 EPA'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, 8 1 % 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 est-aries
             with fewer miles in the "meets use" category and more miles in the "does not meet use" category.
             Interestingly enough, this year's take assessment brought in many more small lakes with good
             overall quality, however, Florida's largest lakes (Lake Okeechobee and Lake George) still
             over-whelm the State average with their large mileages of 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 (24%) 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 WWTPs 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.   Agricultural 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








             major pollution sources (both point and nonpoint) in several of Florida's surface water basins. In
             addition, the mining of phosphate causes surface water hydrological modifications and major land
             use disturbances.

                            ydrologica Modifications. This can take the f
             channelizing slow moving waters, or dredging, draining and filling wetlands. 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
             the effect of hydrologic modification is difficult. Dredge and fill activities result in a loss of
             habitat. 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 contamination in the water and contaminated sediments of the Miarni
             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 connections 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 Miami River and adjoining waters of
             131scayne llay are hundreds of times higher than State criteria. Ftfforts are being made by the City
             of Miami and Dade County to correct these problems.

                                                                                                                  Xii













                                Southwest Reizion 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 southwest Florida:

              This area of the State has many good water quality coastal rivers, often with significant spring
              flow. The major pollution sources are associated with urbanization around Tampa and phosphate
              mining and processing operations.

              The rivers along the west coast of Florida from Waccasassa River to the Anclote River are mostly
              small, spring-fed streams and generally have good water quality. However, problems of high
              nutrient inputs and high bacterial counts exist for many of these rivers. High total coliform counts
              in the Weeki Wachee River resulted in the closure of Rodgers Park to swimming. The only large
              river basin in this stretch of the west coast, the Withlacoochee River, originates in Green Swamp,
              but also has significant ground water inflow. This basin generally has good water quality.

              The upper portion of Boca Ciega Bay and its tributaries have fair to poor water quality. Water
              quality problems are caused by runoff and wastewater discharges. The Hillsborough River has a
              considerable number of problems in its upper reaches and tributaries to these reaches. Pollution
              sources in the upper basin and tributaries include citrus processing, wastewater discharge, and
              construction and agricultural runoff. The lower portion of the Hillsborough River has been
              dammed to form a drinking water reservoir. The reservoir has frequent algal blooms and
              occasional fish kills due to low DO. The estuarine portion of the I-Ellsborough River is degraded
              by urban runoff from Tampa and severe bank modification (sea walls). Lake Thonotosassa, in the
              Hillsborough River Basin, receives excess nutrient loads from streams entering it. These loads
              have caused algal blooms and fish kills. This lake is a SWIM priority waterbody.

              The Alafia River is degraded by phosphate mining activities in the eastern portion of its basin.
              The surficial aquifer is degraded by seepage from gypsum stacks and this seepage enters the
              Alafia. The upper Alafia's reaches are particularly heavily impacted. Sources of pollutants to
              these two waterbodies are point source discharges, runoff from mined and barren lands, and spills
              originating from clay settling ponds. The lower Alafia River has elevated nutrient levels, low DO,
              and on occasion, fish kills and algal blooms. Radium levels in this river are some of the highest
              found in streams on the west coast of Florida. The biological and water quality degradation and
              recent improvement of the Tampa Bay system have been documented. Causes for this
              degradation have been identified as loss of vegetation in coastal areas, dredge and fill activities,
              destruction of submerged habitat and increased pollutant loading. Sources of pollution are
              wastewater discharges, storrawater runoff, spills and wash off at fertilizer loading docks, and oil,


                                                                                                             Xiii








            grease, and fuel from the shipping industry. Tampa Bay is part of the National Estuary Program.
            A plan has been designed and is beginning to be implemented to improve conditions in the bay.

            Tampa Bay also receives water from the Hillsborough, Manatee, Little Manatee, and Alafia
            Rivers. These rivers can also contribute nutrients or toxics to the bay in addition to point and
            nonpoint sources located around the bay. Hillsborough and Old Tampa Bays, have historically
            had eutrophication problems. Trends in Hillsborough Bay indicate that conditions are improving.

            The Sarasota Bay basin has fair to good water quality. The major pollution sources are urban
            runoff, which affects both the tributaries and the bay, historical V;IWP discharges, and septic
            tanks. Actions have been taken to upgrade WWTP to advanced treatment. Sarasota Bay is also
            part of the National Estuary Program. Studies have been initiated to address the problems of the
            bay.

            The Peace River has several problems, most of which originate in the upper reaches of the system.
            Tributaries to the upper Peace River originate from lakes which have eutrophic conditions.
            Sources of discharge to the upper Peace River include phosphate mining, fertilizer and other
            chemical manufacturing, discharge from WWTP, citrus processing, and runoff from agriculture
            and urban areas. Water quality in the middle and lower Peace River improves although it still has
            very high phosphorus values. Unmined tributaries are important sources of high quality water and
            benthic fauna for recolonizing the main channel when it becomes stressed.


            Many of the lakes in this basin have poor water quality. Banana Lake is considered to be the most
            polluted lake in the State. Sources of pollution to these lakes are historical direct discharges from
            WWTP, runoff from agricultural activities and phosphate mining, and industrial effluent
            discharges.


            The Myakka River has good water quality although it has naturally low DO concentrations from
            swamp drainage and has nutrient loading from agricultural runoff and natural phosphate rich soils.
            The river is impounded in its middle reach to form upper and lower Lake Myakkas. The upper
            lake is eutrophic with dense growth of hydrilla and hyacinth.



            The Charlotte Harbor Estuary system generally has good water quality. Phosphorus loading can
            be high as a result of contributions from the Peace River, which is affected by phosphate mining,
            and from the Myakka and Caloosahatchee Rivers' nonpoint source nutrient loading. The harbor is
            affected by urbanization, but still supports a healthy estuarine habitat.

                                   INTRODUCTION AND METHODS


                   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:



                           1.      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 waterbody 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 Seechi 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 i  nto 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 EPA's R173 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 tniles) 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 wat 'erbody 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
                 available). The area of lake and estuary waterbodies was determ@ined with crude GIS aerial
                 measurement techniques (if estuary waterbodie's 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 IBM 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 categories (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 watcr 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.
                    Mssing water quality parameters and missing water quality categories are ignored in the
                    final calculation. Therefore, the final WQ1 is based on an average of anywhere from 1 to 6
                    water quality index categories. Table 5 shows an example calculation of the WQI. The
                    WQI 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 cl  assifying 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 takes 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 atrophic 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 limiting 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 trendinformation 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.

                       actual criteria is dependent on water hardness which was assumed to be 100 mg/I as calcium carbonate
                      since hardness was not available in all waterbodies








                   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 surface waters 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:


                           I .      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 wat      erbodies,
                                    release of radioactive materials to groundwater, discharge of acid mine
                                    drainage and depletion of water supplies in aquifers.


                                                                                                                              12









                          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
                          LD             Land disposal
                          UR             Urban runoff

                          IND            Industrial site runoff
                          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 305(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:

                          I .    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 of 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 chemicals 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.




                                                                                                                 13







                                  7.        Debris. This category includes trash ranging from Styrofoam 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 which 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.


                                                                                                                                                       14









                          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 all 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 runoft) 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

                                                     Toxic Pollutant Assessment


                 The assessment of toxic pollutants in Florida's waters was accomplished by an inventory
                                                         or 1991-93 (Table 9). The Florida surface water
                 of 9 STORET toxic metal parameters f
                 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 a 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 mi 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 1ï¿½88 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.

                      Ecological Characterization

                      The Alafia River, formed by the confluence of the North Prong and the South Prongs, is a blackwater river
                      located in Hillsborough and Polk counties, draining approximately 460 square miles. From the
                      headwaters in the swamp and prairie area south of Mulberry, Florida, the river flows 24 miles westward
                      through coastal lowlands prior to entering the southern end of 11illsborough Bay. The discharge of the
                      Alafia River averages 330 cfs above Lithia Springs which contributes about 50 cfs, flow. Although there
                      are a few springs, surface runoff contributes most of the flow. Its heavily vegetated main stem masks
                      impacts in the headwater tributaries which have been seriously disrupted by phosphate mining activities.



                                                                                                                                      17








                   Land use categories in the Alafia River basin include agriculture, rangeland, and barren land (12%). The
                   relatively high percentage of barren land reflects the fact that the basin includes an area of extensive
                   phosphate mining and processing operations. The lower basin has considerable urban development.

                   The major pollution sources in this basin are the phosphate mining and processing industries. Also,
                   Mulberry and Lakeland both have point source discharges to the Alafia River North Prong. Most of the
                   phosphate processors are located along the North Prong, whereas mining occurs in both the North and
                   South Prong drainages. Simply stated, phosphate processing involves strip mining of calcium phosphate
                   deposits and treating them in suffuric acid to produce phosphoric acid (from which fertilizers are made)
                   and calcium sulfate (gypsum). Pollutants evolved in this process are strong acids, phosphates, fluorides,
                   sulfates, ammonia, and low levels of radiation., Pollutant loading occurs through point source discharges,
                   runoff from mined and barren lands, and occasional spills of water from settling pools (slime ponds). The
                   surficial aquifer is degraded by seepage from gypsum stacks (CaS04 waste), and this aquifer water seeps
                   laterally into the river bed. The processing operations cause worse pollution problems than mining
                   operation. Both the North and South Prong reaches exhibit high nutrient concentrations and frequent DO
                   sags; however, the North Prong of the Alafia has considerably poorer water quality.

                   A biological study of the Alafia Basin also indicated severe stress to both macroinvertebrates and
                   floodplain vegetation in the North Prong. The report suggested that a significant problem in the river was
                   toxicity from hydrogen sulfide, a toxic sulfur compound found when oxygen levels are low. The South
                   Prong also showed stress, though not as pronounced. The study also indicated some community
                   composition shifts from what would be expected in a similar unaffected stream.

                   Both reaches flow through heavily vegetated wetlands which take up nutrient and dilute sulfates so that
                   water quality is much improved at their confluence. Lithia Springs also contributes about 51 cfs of flow in
                   this area. The water quality, however, is variable because the nature of the upstream discharge tends to be
                   in slugs of highly polluted waters as well as some continuous flow. The effect of these slugs on the lower
                   river and bay is poorly documented. The river below the confluence of the North and South Prongs is
                   used recreationally for tubing and canoeing.

                   The lower Alafia River also exhibits poor water quality with elevated nutrients, depressed DOs, and
                   occasional algal blooms and fish kills. These problems appear to be caused by urban runoff, upstream
                   nutrient loading and the tidal influx of Hillsborough Bay waters. Cargill (formerly Gardinier), a
                   phosphate processing facility located at the mouth of the river, has had a history of environinental
                   problems contributing to the degradation of the lower Alafia. Discharges from a gypsum stack have built
                   up a layer of calcium fluoride at the mouth of the river and in the bay. These sediments do not support a
                   healthy biological community. The company has also been responsible for some major acid spills into the
                   river and Tampa Bay wetlands, the most recent in 1989. The Cargill Company is investing a large
                   amount of effort and money to update and safeguard their processes. The estuarine deposits have been
                   partially excavated, a new "state of the art" gypsum stack will replace the old one which will be
                   permanently closed and sealed, and plans for on-site stormwater diking and treatment are being instituted.

                   Other reaches in the basin have historically exhibited water quality problems. Tributaries such as Bell
                   Creek and Turkey Creek are impounded and exhibit poor water quality because of low or intermittent
                   flows and high nutrient and bacteria levels attributed to runoff from rangeland and residential
                   development.

                   Water from Buckhorn and Lithia Springs is very high in nitrates. Septic tanks, stormwater seepage via
                   sinkholes and historic citrus farming have been implicated as the cause.










                     Finally, it should be noted that radium levels in the Mafia River are higher than any other stream on the
                     wcst coast of Florida. The radium source is presently unknown, but probably attributable to phosphate
                     mining residues and discharges.

                      Fish kills occurred in Clam Bayou and Palm Ridge Lake during the

                    Ecological Characterization

                    The Charlotte Harbor estuary is one of the largest bays in Florida, covering 119 square miles of Charlotte
                    Harbor proper as well as Pine Island Sound (71 square miles), San Carlos Bay (23 square miles), and
                    Matlacha Pass (23 square miles). The northern part of Charlotte Harbor receives fresh water from the
                    Peace River and Myakka River. The eastern side of the bay also receives drainage from several small
                    coastal creeks and canals. San Carlos Bay is an extension of the Caloosahatchee River estuary.



                                                                                                                             25









                    Charlotte Harbor proper is heavily influenced by flow from the blackwater, phosphorus-laden Peace River.
                    Pine Island Sound and Matlacha. Pass have less fresh water inflow. Mangroves line the shorelines and
                    create hundreds of small islands throughout the area. They also support more seagrass areas. San Carlos
                    Bay's water is influenced by the Caloosahatchee River. The basin is a productive nursery area for marine
                    life.


                    Urban development in the basin is heavily concentrated in the north at Port Charlotte and near the mouth
                    of the Peace River at Punta Gorda. There is also a localized urbanization in the south, at the mouth of the
                    Caloosahatchee. However, more and more of the drainage area is being developed, mostly as massive
                    communities. Most of the rest of the shoreline is mangrove forests. The barrier islands are moderately
                    developed, primarily for tourism. The economy of the area is based on tourism, retirement communities
                    and fisheries.

                          Mgemc Impacts

                    Water quality in this basin is generally good. The predon-driant pollution problems are associated with
                    development: bacteria from accelerated urban runoff through canals and sediments from construction and
                    reverse osmosis effluent discharges. Nutrient levels, particularly phosphorus, are elevated, and Secchi
                    readings are somewhat low in areas. High phosphorus levels primarily originate from the Peace River
                    Basin. Nutrient loading in San Carlos Bay may be the result of urban runoff in the Ft. Myers area and
                    agricultural runoff in the Caloosahatchee River drainage. Upper Charlotte Harbor is probably affected to
                    some degree by urbanization at the mouth of the Peace River. There have been reports of declining
                    fisheries and shellfishing is periodically closed because of bacteria. The timing and possible quality of
                    fresh water inflows into the north end of Matlacha Pass are affected by an extensive canal system in the
                    largely undeveloped northern portion of Cape Coral. The most serious water quality problem in the basin
                    is the Sanibel River located on Sanibel Island at the southern end of the Charlotte Harbor Basin. It has
                    previously received domestic wastewater and runoff from the island's more developed areas. Leachate
                    from local WWTPs has been controlled, but storinwater runoff remains a problem. The area has not been
                    sampled recently, but the Nonpoint Source Assessment still indicates impairment of the water body.

                    A technical advisory committee was. formed in the early 1980s to recommend necessary planning actions
                    in this rapidly growing and developing basin area. The Southwest Florida Water Management District is
                    currently developing a SWIM plan for Charlotte Harbor.

                Ecological Characterization


                This coastal basin stretches from Crystal River on the north to Tampa Bay on the south and consists of
                many short meandering streams in the northern portion of the basin. Most of these have tidal
                characteristics, and four, the Weeki Wachee, Chassahowitzka, Homosassa and Crystal Rivers, have
                headwaters which are major Florida springs. They empty into the large sawgrass and Juncus dominated
                estuary that lines this entire 40 mile stretch of the coast. The Department of Natural Resources recently
                commissioned a study of the main spring of the Homosassa, River located at the Homosassa Springs
                Wildlife Park and preliminary results indicate the spring production has fallen below first order
                magnitude status.

                The waterbodies in this basin are typically clear, high transparency waters which are major recreational
                and economic attractions. For example, Crystal River is one of the south!s most popular diving sites and a
                wintertime manatee refuge. Crystal River and Kings Bay are designated as Outstanding Florida Waters.


                There are two streams in the central portion of the basin, the Pithlachascotee and Anclote Rivers, each
                with a length of over twenty miles. Both have their origin in the same swampy area and are blackwater
                rivers. They are affected by urban growth especially in the lower coastal segments. The southernmost
                reaches of the basin includes Boca Ciega Bay, St. Joseph Sound, and several St. Petersburg area feeder
                creeks and canals. This area is heavily urbanized.


                Anthrovogenic Lmppc-ts


                The spring-fed rivers in the northern basin generally have very good water quality. Crystal River has
                relatively high nutrient input and because of its high transparency it is subject to dense aquatic weed
                growths in the Kings Bay area. ffistorical sources of nutrient input are the Crystal River WWTP
                discharge, spring discharge, septic tanks and stormwater runoff. The City of Crystal River has completed
                construction of a new inland spray field and has eliminated the surface discharge from their wastewater
                treatment facilities. In addition the Homosassa River has a history of bacterial problems of unkn own
                source,possibly residential canals and septic tanks. Also, the Weeki Wachee has some bacteria problems.
                Rodgers Park on the river has been closed since summer 1989 because of high coliform bacteria counts.
                The source of the bacteria is unknown. The lower Pithlachascotee and Anclote have also had some
                bacteria problems, presumably from septic tank drainage and/or urban runoff. There have been some
                swimming bans in the area.


                The worst water quality in the basin is found in the highly developed southern portion. Pinellas County is
                almost entirely urbanized; the largest cities are Clearwater and St. Petersburg. The barrier islands and
                beaches are also urban. All of the feeder creeks and most of the lakes in the area have pollution problems
                with elevated coliform and nutrient concentrations and depressed DO values. The Nonpoint Assessment
                reports moderate impairment with low DO, excessive algal and weed growth, high bacteria counts and
                swimming closures in these urban lakes and canals. The Tampa District sampled the Cross Bayou Canal
                (and Joe Creek, a major tributary) 3 times in 1975 and discontinued their program. Pinellas County
                initiated a sampling program in August 1990, which includes this waterbody. The WWTP sources
                previously discharging to these waterbodies have been removed. Pinellas County's South Cross Bayou
                WWTP (33 MGD capacity) is under consent order to discontinue deep well injection of their wastewater
                by April 1999. They have applied for a permit to shift all of their effluent (AWT) disposal to a surface
                water discharge (Joe's Creek) and a reuse system. Bear Creek which also receives urban drainage, has

                                                                                                                                     33










                 poor water quality. A portion of Long Bayou was impounded in the 1960s to form Lake Seminole. The
                 Lake has almost no circulation and receives urban drainage. Consequently, it has a nearly perpetual algal
                 bloom and poor water quality. Pinellas County and the SWFWMD have been engaged in an intensive
                 study of the Lake for the past few years. The County is beginning to develop a watershed management
                 plan for the Lake's basin.


                 A DEP intensive study has been conducted in St. Joseph Sound. It indicated elevated chlorophyll values
                 in the estuary near Clearwater and poor water quality in some of the feeder creeks. The ongoing SWIM
                 study of Crystal River/Kings Bay has generated numerous reports and data concerning current water
                 quality and impacts in the area. Of final note is the ongoing public acquisition of land in this area. The
                 former Lykes Ranch near the Chassahowitzka and the adjoining Walker wad have been acquired by the
                 SWFWMD under the Save Our Rivers Program. Under the CARL and Preservation 2000 programs, the
                 Homosassa Reserve, Pappas property, and additions to St. Martin's Marsh Aquatic Preserve are planned or
                 being acquired.

                       ï¿½ Tampa has applied to the SWFWMD to increase the consumptive use of the
                         river. A major study of the lower river (estuary) will accompany the
                         permit review.
                       ï¿½ Health advisories recommending limited consumption of largemouth bass
                         due to mercury content have been issued for the Hillsborough River
                         drainage system.
                       ï¿½ A large fish kill occurred on the Hillsborough River between Sligh and
                         Osborne Avenues in Tampa, June, 1990. Approximately 10,000 sardines
                         were killed.

                  Ecological Characterization


                  The Hillsborough River originates in the Green Swamp near the origin of the Withlacoochee (South)
                  River. The two rivers actually have a swamp connection called the Overflow, which is important to their
                  hydrologic cycles. Flowing southwesterly, the river channel becomes defined and flow is supplemented by



                                                                                                                                   44








                the discharge from Crystal Springs to form a swift, clear stream. Aside from the wetlands, land use in
                this upper basin includes rangeland, orchards, and some urban drainage from the City of Zephyrhills and
                its airport.


                Below Crystal Springs, a major drainage, Blackwater Creek, joins the river before it enters the
                Hillsborough River State Park. Within the park is a 150 yard stretch of shoals and additional inflow of
                relatively good quality streams. The upper Blackwater Creek drainage also has urban, citrus and
                rangeland runoff.

                Past the park, several tributaries enter from the'northern, less-developed portion of the basin. Also, the
                Pemberton-Baker Creek/Lake Thonotosassa drainage enters from the south. This drainage also has urban,
                citrus and livestock utilization. Further downstream, just before entering Tampa, is a flood control
                structure which can divert flow through the Tampa Bypass Canal to Tampa Bay. The next feature of the
                river is a 4 mile long reservoir from which Tampa draws about 75% of its drinking water.


                From the dam to the bay, about 10 miles, the river flows through the heart of urban Tampa, and the
                channel is highly modified with seawalls, riprap and bridges. It receives freshwater inflow (at about 20
                MGD) from Sulfur Springs, but is otherwise brackish. Little remains of native vegetation along this
                stretch of the river.

                This basin is difficult to assess in that professional opinions vary and there is limited monitoring data in
                STORET for such a highly utilized area. In general, dissolved oxygen in the Hillsborough River is low
                except where the river flows off the central highlands to the coastal lowlands. Most of the tributaries are
                sluggish, blackwater streams which are commonly low in DO. In addition to being located in a phosphate
                rich area, inputs to the river of both phosphorus and nitrogen are generally further increased due to both
                point and nonpoint sources.


                The upper Hillsborough River, near Zephyrhills and Crystal Springs, is apparently undergoing rapid
                urban development and construction. The Nonpoint Source Assessment rates it as severely impaired with
                high sedimentation and nutrients and exhibiting algal and weed problems, declining fisheries and fish
                kills. Water quality parameters indicate fair conditions for the REACH. An improvement to water
                quality is Crystal Spring's contribution of about 58 cfs of high quality ground water, particularly in the dry
                season.


                Other northern tributaries, upstream of the park, include Big Ditch, which has historically had poor
                ratings due to mining and rangeland runoff, but has not been assessed recently. The Blackwater Creek
                basin has several pollution problems, especially in the upper basin. Itchepackasassa. Creek (a tributary of
                Blackwater Creek) has historically had high nutrient, bacteria and toxics levels, as well as low DO
                concentrations and several fish kills. The source of the problem may have been discharges from two citrus
                processing companies and runoff from a pesticide packing and shipping company. The latter company
                has undergone significant cleanup and drainage improvements. There are several other small dischargers
                to the creek as well as ninoff from rangeland and dairy operations. DEP's Point Source Evaluation
                Section conducted an intensive survey of the Creek during September, 199 1. Blackwatcr Creek also
                suffers from range and agricultural runoff. Despite these problems, the upgrades at the pesticide company
                and at other industrial dischargers have led to optimistic reports of water quality in this basin. The lower
                Blackwatcr Creek drainage has more vegetation and less intense land use and thus has a cleansing effect
                on the creek.



                                                                                                                                        45












                  Both the Nonpoint Source Assessment and water chemistry data indicate improved conditions in the river
                  in its middle segments, especially in Hillsborough River State Park. These segments retain much of the
                  natural bank vegetation; there is input of some relatively good water quality tributaries; and flow is more
                  rapid which increases DO and habitat diversity. Nonetheless, high coliform counts prevent swimming in
                  the river at Hillsborough River State Park.


                  Lake Thonotosassa and its tributaries (Baker Creek and Pemberton Creek) receive excessive nutrient loads
                  averaging 0.7 - 1.9 mg/I phosphorus in streams entering the lake. The loading results in algae blooms,
                  fish kills and cutrophic conditions in the lake. There were also high bacterial counts in the creeks.
                  Dischargers into this system appear to account for much of the pollution. The Plant City WWTP, which
                  also receives industrial wastes, contributes significant loading of phosphorus (over 40,000 lb. a year), but
                  its discharge is not directly to the creek or lake. Plant City will cease discharging to the Lake
                  Thonotosassa watershed by 1997. Waters leaving eutrophic Lake Thonotosassa. flow to the Hillsborough
                  River through Flint Creek. Because of the lake outflow, waters in this creek carry high phytoplankton
                  loads which are conspicuous at the confluence with the blackwater Hillsborough River. Nonpoint sources
                  include urban and rangeland runoff. Lake Thonotosassa is a priority SWIM waterbody.


                  The southern basin tributaries are mostly rated as good with few pollution sources. However, the lower
                  Cypress Creek, which Toughly parallels Interstate Highway 275, appears to be more severely impaired by
                  urban construction activities. The upper Cypress Creek basin is undergoing some residential land
                  development and has low DO and high nutrients typical in the basin.

                  The lower section of Hillsborough River, up to the reservoir, although affected by the upstream pollution
                  sources, has improved water quality. At the reservoir, however, nutrient loads from upstream
                  Hillsborough River, some residential drainage, and recreational use have caused severe aquatic weed
                  problems and some algae bloom problems. These problems are of particular concern as the reservoir is a
                  drinking water source of Tampa. Below the dam, the river is tidal and brackish. It receives a large
                  sediment load with metals and other typical runoff pollutants from Tampa. Its banks are lined with
                  seawalls, buildings, and stormwater outfalls. Portions of the river bed are under investigation to
                  determine if they can be restored.

                       * IMC Fertilizer has proposed an 18,290 acre expansion of its phosphate
                         mining operation in southeastern Hillsborough County, which may affect
                         the North Prong of the Little Manatee River.
                       * A major area of Hillsborough County north of the Little Manatee River
                         was rezoned from agriculture to residential several years ago.

                   Ecological Characterization


                   The Little Manatee River Basin is a small (222 square miles) basin located between the Alafia and
                   Manatee River Basins discharging into middle Tampa Bay on its eastern shore. Among the principal
                   creeks and rivers flowing into Tampa Bay, it is considered to be in the best condition. The Little Manatee
                   River is formed by the confluence of the North and South Forks. Both are fairly natural with no large
                   commercial or residential developments near them. The banks of the Little Manatee retain. natural
                   vegetation throughout most of the river course, but intensive agricultural land use is occurring close to the
                   river channel in areas. River flow fluctuates widely so that at low flow there are steep banks, and at high
                   flow, the water will almost reach the canopy of overhanging trees. However, average flow of 170 ds was
                   measured at Highway 301, about 15 miles upstream of the river mouth. The river channel in both prongs



                                                                                                                                     52









                and the mainstream is narrow and sharply meandering until it reaches the tidal and estuarine and portion
                near the Interstate Highway 75 crossing.


                Land use in the basin is predominantly agriculture and rangeland. There is one urban center, Ruskin,
                near the river mouth at Tampa Bay. However, with the recent completion of the 1-75 interstate highway,
                population is expected to increase by as much as 40% in as little as two years.

                The Little Manatee River has historically had good water quality and aesthetic and recreational value.
                The main river channel (excluding the South Fork and upstream portions of the North Fork) was declared
                an Outstanding Florida Water. There are no major water quality problems in this basin; however, the
                reaches in this basin have elevated bacteria and nutrient levels. These problems are likely due to runoff
                from rangeland (bacteria and nutrients) and agricultural areas (pesticides and nutrients). Strearnflow and
                water quality data from six gaged sub-basins monitored by the SWFWMD indicate that substantial
                amounts of excess crop irrigation water enters the river along sections of the North Fork. Nutrient
                enrichment and flow supplementation have increased significantly enough to be considered threats to the
                continued quality of this river. Water is pumped from the upper river into a 4000 acre off-strewn
                reservoir which stores cooling water for a major power plant. Florida Power and Light has two point
                source discharges into the South Fork of the Little Manatee River consisting of seepage from Lake Parrish
                (their cooling reservoir), with mixing zones for iron and pH in the river.


                In the lower river, the Ruskin area is still serviced by septic tanks and package plants, and there are
                numerous tropical fish farms in the watershed at present. Water quality data does not indicate any serious
                problems in this area. The Southwest Florida Water Management District is studying the river and a
                report is pending. The lower river and nearby bays at its mouth are some of the last areas in Tampa Bay
                where mangrove forests and seagrass beds are still abundant. The Hillsborough County Endangered Land
                Program is trying to buy islands in this area.

                      Ecological Characterization

                      The headwaters of the Manatee River originate in the northeastern comer of Manatee County. The river
                      flows approximately 33 miles southwesterly to Tampa Bay and drains 375 square miles. The river is
                      impounded a, Lake Manatee to provide the drinking water supply for Manatee County. Downstream, west
                      of Fort Homer, the Manatee River forms a wide, tidally influenced estuary. Principal tributaries of the

                                                                                                                                                                      59









                 Manatee include Gamble Creek and the Braden River, which is also impounded to provide drinking water
                 for the City of Bradenton. The Manatee River has several distinct habitat types. The upstream portion is
                 a blackwater steam meandering through a canopied corridor. Rangeland and agriculture are the
                 predominate land use in this part of the basin. Lake Manatee provides a lacustrine habitat near the middle
                 of the basin. Citrus orchards are common here. Downstream of the lake, the river is again a meandering
                 stream and is a recognized canoe trail. Finally, the mouth of the river is a mangrove lined estuary which
                 has been extensively urbanized by the towns of Bradenton, Palmetto and Ellenton.


                  Anthropogenic Impacts


                 Generally, this basin has good water quality. The major problem in the fresh water portion of the basin is
                 increased nutrient levels in the Manatee River Reservoir. There are no point sources in the area to
                 account for these values, but the lake receives excessive nonpoint source nutrient loading from orange
                 groves and rangeland. Some phosphate mining operations occur near the North and East Forks. The
                 high nutrient levels in the reservoir promote algae and weed growth. The lake has nearly year-round algal
                 bloom problems which are treated with frequent applications of copper sulfate (though a reduction in
                 amount has taken place in recent years). Lake data collected by the Manatee County Public Works
                 Department (PWD) indicated nutrient values in the "poor" TSI range, but chlorophyll levels were held
                 artificially low because of the copper treatments. Consequently, copper levels were relatively high (above
                 state criteria for surface waters and potable water supplies) both within and downstream of the lake. PWD
                 is acting to improve the conditions in the lake by: 1. developing a pilot project to determine the
                 effectiveness of requiring best management practices (BMP) of agricultural operations; 2. instigating
                 aeration projects in Gilley Creek and Boggy Creek; and 3. starting a watershed land acquisition project.
                 EPA will also be investigating BMPs in this drainage.


                 Gamble Creek has not been sampled recently, but has historically had nutrient and DO problemsfrom
                 agriculture and construction runoff, A major fish kill was reported in the summer of 1989.


                 During the rainy season of the year, nutrient and organic nitrogen loading from runoff cause periods of
                 high chlorophyll and low DO values in the estuarine areas downstream of the reservoirs. Although
                 STORET data arc limited, an intensive survey of the lower Manatee and Braden Rivers for a wastcload
                 allocation survey showed that these areas had fair water quality predominantly because of DO problems.
                 The point source loading in the estuary should have decreased with the recent upgrading of the Bradenton
                 WWTP which was required by special legislation which makes advanced treatment mandatory for
                 discharges going to Tampa Bay. However, Manatee County consumes most or all of the dry season flow
                 coming into the lake, thus decreasing flushing downstream and leading to a more saline estuary.
                 Currently, the major source of pollution to the estuary appears to be runoff from upstream agricultural
                 sources (and Lake Manatee) and urban runoff from Bradenton. The Braden River Reservoir has high
                 nutrient and bacteria problems. Potential sources of these problems are rangeland runoff and septic tank
                 leachate. Upstream of the impoundment, the river has good water quality.


                 Tropicana has constructed a new wastewater treatment system to improve the quality of their effluent.
                 The City of Palmetto is reviewing the potential of either going to total reuse with their wastewater, or
                 hooking up to. Manatee County's wastewater system.

                        A proposal by Sarasota County to divert water from the Myakka River for
                        a potable supply and replace the volume with treated WWTP discharge
                        is being discouraged by DEP because of the OFW status of the Myakka.

                  Ecological Characterization


                  The Myakka Basin is located in a transitional area between temperate and subtropical habitats. The upper
                  basin is in a flat, marshy area with a smallffinging cypress floodplain. This upper portion of the basin is
                  very sparsely populated or developed. It is used mostly for pasture land and some citrus groves. The
                  blackwater river then enters two successive impoundments, upper and lower Lakes Myakka. The latter is
                  only partially impounded. This portion of the basin is also sparsely populated and is mostly included in
                  the 45 square mile Myakka River State Park. It is interesting to note that the river receives some ground
                  water flow from a 150 foot deep sinkhole at the base of lower Lake Myakka. Below the park, the river
                  winds its very crooked course through undeveloped marsh and swamp prairies until it begins to widen into
                  the estuarine portion of the river. This area receives flow from the river's two main tributaries, Deer



                                                                                                                                   66








                Prairie Creek and Big Slough Canal. The North Port and Port Charlotte development he just east of the
                Myakka estuary.


                Because the Myakka Basin is relatively undeveloped, and because it contains so many habitats (marsh,
                swamp, prairie, flatwoods, hammocks and estuary), many species of endangered wildlife have been found
                there. It is also a popular recreation area. Much of the river has been designated as a State Wild and
                Scenic River and as an Outstanding Florida Water.

                The headwaters of the Myakka River arise from marshes in Hardee County in southwestern Florida. The
                river traverses approximately 54 miles, draining roughly 540 square miles prior to discharging to
                Charlotte Harbor. The average flow of the Myakka River is estimated at 600 cfs near its mouth at
                Charlotte Harbor.


                Agthropggenic LMPNU-


                This basin generally has very good water quality and supports both productive freshwater and estuarine
                habitats. The river originates from swamp drainage and is very sluggish, often with zero net flow during
                the dry spring seasons. DO values are typically low. Tidal influence on flows and salinity can extend
                approximately 20 miles upstream. Part of the upper basin drains phosphate rich areas which, combined
                with agricultural and rangeland runoff, causes the river to have elevated nutrient levels. Upper Lake
                Myakka is eutrophic: with dense hydrilla and hyacinth growth and depressed dissolved oxygen
                concentrations. The lake provides habitat and feeding areas for abundant wildlife.

                In the lower basin, Deer Prairie Creek and Big Slough Canal both drain rangeland. The latter has been
                channelized in its upper reaches to enhance this drainage. In its lower reaches, it traverses some
                urbanized areas and receives drainage from residential canals. Big Slough shows elevated colfform and
                nutrient levels presumably due to pasture and urban development area runoff. There is relatively little
                development along the estuary which maintains much of its pristine, mangrove vegetated shoreline. The
                estuary is threatened by encroaching growth from developments to the east.

                        at a facility located 19 miles above the river mouth. The expansion of the water
                        treatment plant and the extension of a regional supply pipeline to Sarasota County
                        is called the Peace River Option. Water storage will rely on an offstream reservoir and
                        aquifer-storage-recovery facilities. Regulatory review (including hydrologic and environmental)
                        of the Peace River Option will occur in the summ er of 1994.



                 Ecological Characterization


                 The Peace River originates in the Green Swamp and some of the numerous partially connected lakes of
                 central Polk County. It coalesces into a defined stream near Bartow and flows generally southwest for
                 approximately 105 miles, entering Charlotte Harbor. The drainage area encompasses over 2,300 square
                 miles. Numerous lakes and large areas of poorly drained swamps in the headwaters of the Peace River act
                 as important recharge areas for the Floridan Aquifer. The mean flow of the Peace River is 900 cfs,
                 recorded at Arcadia 36 miles upstream from the river mouth.


                 The Peace River is a blackwater stream. The river corridor itself has little development and is mostly
                 lined by cypress and hardwood floodplain. It is a popular canoe trail from Ft. Meade to Arcadia. Primary
                 tributaries of the Peace River include Peace Creek, Saddle Creek, Charlie Creek, Horse Creek, and Shell
                 Creek. Major urban areas in the upper basin include Lakeland, Winter Haven and Bartow. At the river's
                 mouth are Port Charlotte and Punta Gorda.


                 Land use in the upper portion of the Peace River Basin is predominantly agricultural. An additional large
                 percentage of barren land (about 251/o) reflects the extensive phosphate mining activities that have been
                 prevalent in the upper basin and the headwaters of many of its tributaries. In the lower portion of the
                 Peace River Basin, land use consists primarily of agriculture and rangeland. Citrus groves are prevalent
                 in the middle river reaches. Pollution sources in the Peace River Basin include domestic wastewater
                 discharges, industrial discharges from phosphate mining activities, chemical and citrus processing plants,
                 and surface runoff from urban, agricultural, rangeland and barren (mined) areas.


                 Anthrovogenic I!ppacts


                 This basin has four major classes of pollution sources that affect different areas along the river and its
                 tributaries. In the northern portion of the basin both domestic and industrial point sources and urban
                 stormwater severely impact water quality. Another portion of the upper basin has been affected by
                 phosphate mining. Most of the major tributaries throughout the basin have agricultural and rangeland
                 runoff to a greater or Icsser degree.


                                                                                                                                    75












                   The worst water quality problems originate in the upper portion of the basin. Lake Parker, Banana Lake,
                   and Lake Hancock and their tributaries (Stahl Canal, Banana Lake Canal, and Lake Lena Run) have some
                   of the poorest water quality in the State with elevated nutrients, periodic low DO, high pH, high bacteria
                   counts and severely depressed biological indicators. Lake Parker is also affected by thermal discharge
                   from a power plant which raises its ambient temperature several degrees above other nearby lakes.
                   Banana Lake has long been considered one of the most polluted lakes in the State. In August, 1990, Polk
                   County began the dredging of almost 1,000,000 cubic yards of sediment from the lake bottom. A
                   tributary, the Stahl Canal, historically received effluent from a Lakeland WWTP. That facility is now
                   discharging to a former phosphate mine converted to an artificial wetland. That wetland drains to the
                   Alafia River. Since the point sources were removed from the system, Banana Lake has shown some
                   recovery (lower chlorophyll values), though nutrients are still elevated. Total phosphorus values greater
                   than 0.80 mg/I were recorded in 1990.


                   Lake Hancock, with extremely poor water quality, is fed by three polluted streams or canals. One of these,
                   Lake Lena Run, had one of the worst water quality index values in the State in 1983. During two
                   sampling events in the spring of 1981, only three species of macroinvcrtebrates were found, which
                   generated a diversity index of less than 0.25. Most of its flow is made up of effluent from three citrus
                   processing companies, a chemical plant, a distillery, the Auburndale WWTP, and runoff from rangeland,
                   a sprayfield, and a dump site for citrus waste. The City of Auburndale only has an emergency discharge
                   to Lake Lena Run. All of their cffluent is reused on citrus groves. DEP has performed several intensive
                   surveys and wasteload allocations of this area over the last ten years. The models have indicated that the
                   flow from the dischargers would actually be beneficial to the stream and receiving lake if the nutrients
                   were removed; therefore, more strict loading limitations have been set. The second problem drainage to
                   the Lake Hancock is from the Banana-Hancock Canal. Finally, upper Saddle Creek, the third Lake
                   Hancock tribuwy, is degraded primarily by urban stormwater runoff.


                   Problems caused in Lake Hancock, as a consequence of the poor water quality in its tributaries and
                   agricultural runoff and phosphate strip mining directly adjacent to the lake, include year-round algal
                   blooms and frequent fish kills. Historically, discharges from Lake Hancock during the rainy season
                   severely affected water quality downstream and caused massive die-offs of river fauna. Recently, the
                   discharges have been timed better and the die-offs have not reoccurred. A lake restoration plan (involving
                   mining the lake) was investigated by a Legislatively-appointed committee, but found to be not
                   economicafly practical. A more recent lake restoration plan put forth by the Florida Game and Fresh
                   Water Fish Commission involved dewatering the lake for a time. It was vetoed due to concerns over Bald
                   Eagle nesting, and strong opposition from commercial (tilapia) fisherman.

                   Between Lakes Hancock and Hamilton, there are several other small loosely connected lakes, streams, and
                   the City of Winter Haven. The lakes receive various combinations of industrial effluent, domestic
                   discharge and urban runoff. Polk County received federal grants to clean up some of the pollution
                   problems in several of these lakes. A 1985 2050) report prepared by Polk County indicates that corrective
                   actions, especially the removal of domestic dischargers, have resulted in marked improvements in the
                   Trophic State Index (TSI). Additionally, the Winter Haven Chain-of-Lakes has been adopted as a SWIM
                   priority. Most lakes, however, continued to be in the eutrophic range of TS1 values. Lake Hamilton was
                   no, included in his study, but presumably is typical of the region's problem lakes. Peace Creek, located in
                   the upper portion of the basin, periodically receives slugs of pollution from some of the upstream lakes
                   (particularly Lake Effie), indirect discharge from the Winter Haven WWTP, and rangeland runoff. it
                   appears from intensive survey sampling and a DEP district study that water quality in lower Peace Creek
                   is often quite good but because of periodic pollution events is rated as fair. The City of Lake Wales

                                                                                                                                        76

                 The Peace River in the vicinity of Bartow, Fort Meade, and Zolfo Springs is degraded by several
                 phosphate mining and fertilizer industries. Strip mining of phosphate rock occurs (or has occurred)
                 within the drainage of the river and most of its tributaries (Bowlegs Creek, Whidden Creek, Little Charlie
                 Creek and Troublesome Creek) in this stretch. Although waters flowing through phosphate strata have
                 higher background concentrations of phosphorus, these mining operations contribute far greater nutrient
                 loading than natural background loads. Furthermore, mining disrupts the flow regime of the smaIl creeks
                 and severely limits habitat for biota. The Peace River relies upon these tributaries for biological
                 recruitment. In addition to the mining operations, this area has many citrus groves so pesticides may cause
                 further threats to aquatic life. The mine in Bowlegs Creek is closing and some of their reclamation area
                 may be given to Ft. Meade to use for final wetland treatment of their WWTP discharge.


                 The City of Bowling Green also discharges to the Peace River just upstream of it's confluence with Payne
                 Creek. The effluent travels to the river via a small tributary that flows through the Payne Creek State
                 Historic Site (a state park and OFW). Bowling Green is currently under a consent order to remove it's
                 discharge from the park and go to reuse or a land application method of disposal.


                 South of Troublesome Creek there are few point sources, except for the City of Arcadia WWTP which has
                 a faulty collection system. The nonpoint sources shift from mining operations to agricultural and
                 rangeland runoff. Because of this less intensive land use and with the confluence of Horse Creek (a
                 relatively undisturbed tributary system) the Peace River exhibits relatively good water quality. The only
                 exception as it enters Charlotte Harbor is high phosphorous content. The Prairie Creek and Shell Creek
                 drainage is threatened by increased urban development occurring in the area. Near its confluence with the
                 Peace River, Shell Creek has been impounded for drinking water; however, withdrawals are relatively
                 small (about 5 cfs).


                 The estuarine portion of the river is affected by the development of Port Charlotte and Punta Gorda.
                 Construction and urban runoff add sediment and nutrients to the estuary. The Punta Gorda WWTP has
                 converted from surface water discharge to spray irrigation. The spray fields, however, are underdrained
                 and flow to Myrtle Slough. The plant has been directed to convert to advanced treatment.


                 A five year study by FGFWFC found that the upper and lower ends of the Peace River have fishery
                 problems, but the middle section is fairly clean with plentifid fish. In the upper section of the river the
                 composition of fish populations, largely gar and tilapia, reflects the environmental impacts of drainage
                 from Lake Hancock and the Peace Creek Drainage Canal.


                 By the time the river reaches Wauchula, better quality water inputs from tributaries change the makeup of
                 fish populations. In the middle section of the river largemouth bass, bluegill and sunfish can be found in
                 addition to tilapia and gar. Diversity decreases near the river mouth at Punta Gorda on the Gulf of
                 Mexico.


                 Charlotte Harbor, and its watershed including the Peace river, has been de   signated as a SWIM waterbody.
                 Diagnostic studies of the strearnflow and watcr quality characteristics of the Peace River are now being
                 done as part of the SWIM plan. An important topic has been the causes of declining flows in the upper
                 Peace River.

                        Sarasota Bay is part of EPA's National Estuary Program.
                        The Cities of Sarasota, Venice And Sarasota County currently
                         have applications under review by DEP for reverse osmosis and/or
                         EDR reject discharges to state waters. Venice and Sarasota County
                         are proposed to discharge to the Intracoastal Waterway. Venice's
                         discharge point will be a combined outfall for their R/O reject and
                         Domestic Wastewater effluent (a relocation of the WArl? discharge).
                         The City of Sarasota is proposed to discharge to Sarasota Bay via a
                         Stormwater outfall at Payne Terminal.


                                                                                                                                91









                     ï¿½ The City of Sarasota also has an application pending for its WWTP to
                         increase the number of discharge days to Whitaker Bayou.
                     ï¿½ The Army Corps of Engineers and Sarasota County's Stormwater Utility
                         are currently considering a flood control project for the tributaries
                         of Whitake Bayou which involve creek channelization . DEP has suggested
                         they explore other alternatives.
                     ï¿½ Dredging of Stamp Pass in Lemon Bay has provoked controversy.
                     ï¿½ DEP has rejected requests from Sarasota County for permit to dredge
                         and reopen Midnight Pass.


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


                 Ecological Characterization


                 The Sarasota Bay drainage area is 268 square miles and extends from Tampa Bay to Charlotte Harbor.
                 Sarasota Bay, Little Sarasota Bay and Lemon Bay have a combined estuarine area of approximately 24
                 square miles. This bay is really more like a sound, protected by a strip of barrier islands and receiving
                 little fresh water inflow. There are several small streams, most of which are less than five miles long, that
                 enter the estuary. Nearly all of these streams and relatively clear waters of the basin support healthy, but
                 degrading, seagrass beds.


                 This basin has two major urban centers, Sarasota and Bradenton, and most of the rest of the area is
                 developed into subdivisions and small municipalities. There is also some agricultural drainage in the
                 basin, mostly from citrus groves in the east section of the basin and rangeland at the headwaters of
                 Phillippi Creek and Cow Pen Slough. Sarasota Bay has been designated in Section 317 (National
                 Estuarine Program) of the Water Quality Act of 1987 as an Estuary of National Significance.


                 Anthropo-genic Impacts


                 The major point source of pollution in the basin is the City of Sarasota WWTP which discharges into
                 Whitaker Bayou. Whitaker Bayou has nutrient, DO and coliform problems. The plant has had a long
                 history of enforcement actions taken against it, and the city has explored a variety of political, engineering
                 and permitting options. The plant has been upgraded to an advanced water treatment facility. Currently,
                 a combined system of "ridge and furrow" seepage irrigation and direct discharges to Whitaker Bayou are
                 being used to dispose of wastewater. The plant is allowed a maximum of 59 days per year of direct
                 discharge (primarily Phillippi Creek area).

                 Agricultural and urban stormwater runoff is also a problem in this basin. Many of the streams running
                 through developed areas are affected by septic tanks. Tributaries and direct runoff supply the bay systems
                 with heavy nutrient loading. Seagrass beds are declining in upper Sarasota Bay, especially the eastern
                 side, presumably because high algae concentrations are reducing transparency. Runoff from the
                 Bradenton area and the Manatee County WWTP "ridge and furrow" seepage irrigation (which actually
                 water a fertilized gladiolus farm) provides further nutrient loading.

                 Sarasota Bay, Little Sarasota Bay and Lemon Bay have been declared Outstanding Florida Waters, which
                 should afford them greater protection from both point source and nonpoint source pollution. However, all
                 are threatened by increased boat traffic, seawalling and the replacement of mangroves by lawns and
                 drainage canals. In association with the National Estuarine Program, several local agencies arc
                 conducting water quality monitoring within the bay and beginning a process of establishing a bay
                 management plan.

                                                                                                                                        9@

               Ecological Characterization


               Tampa Bay is a multi-lobed (roughly Y-shaped) estuarine system which opens into the Gulf of Mexico
               approximately midway down the west central coast of peninsular Florida. The bay is often divided into
               sub-areas: Old Tampa Bay, Hillsborough Bay/McKay Bay, Middle Tampa Bay, Lower Tampa Bay, Boca
               Ciega Bay, and Terra Ceia Bay. The Manatee River estuary is also sometimes considered a section of the
               bay. Geomorphology and a difference in certain chemical and physical properties of the sub-areas are the
               normal criteria utilized to sub-divide the system.


               Tampa Bay is approximately 35 miles long, 10 miles wide, and covers a total surface area of about 346
               square miles with a shoreline of 212 statute miles. The overall estuary is a rather shallow water body,
               having a mean depth of I I feet, with 90% of the total bay area less than 22 feet deep. Tampa Bay was
               reported as being the second largest estuarine system of the 40 estuaries examined along the entire Gulf
               Coast. River systems that empty into the bay include the Hillsborough River, the Alafia River, the Little
               Manatee River and, just south of Terra Ceia, the Manatee River. Because of reduced freshwater inflows
               and the influence of the Gulf of Mexico waters, Tampa Bay waters are of higher salinity and clarity than
               many estuaries. Because of its natural and anthropogenic phosphorus input, the bay is extremely
               nitrogen-limited (i.e., increases in nitrogen can cause algae blooms). Major cities in the basin include
               Tampa and St. Petersburg.


               The tremendous increase in Florida!s population over the past several decades has resulted in increased
               development along the shoreline of the bay. This development, together with increased pollutant loading,
               shoreline and bay bottom alterations, and wetland destruction has led to a gradual degradation of the
               Tampa Bay estuary. Various ecological changes in the bay system over this period of time have been
               documented chemically, physically and biologically. Historically, a much higher proportion of production
               in the bay was based on mangrove forests and seagrass beds. With increased nutrient input,
               phytoplankton are becoming a more dommant member of the bay community.


               The degradation of the bay has spurred intensive efforts over the last ten years by local scientists,
               environmental organizations, politicians and engineers to reverse the trends. Protective management
               policies, legislation and regulation have been adopted. As a result, at least one portion of the bay's system,
               Hillsborough Bay, has shown some recovery, based on chlorophyll levels.

               Biological and water quality degradation of the Tampa Bay system has been well documented. The
               primary reason for this degradation is the intensive residential and industrial development of the area
               which has led to: 1. Vegetative denudation and associated erosion and stormwater runoff problcms in the
               coastal zonc area;
               2. Alteration of bay circulation patterns by channels, causeways and spoil islands;


                                                                                                               100










                    3. Dredging and filling projects related to harbor development, industrialization, and finger fills for
                    increased housing;
                    4. Attenuation of fresh water inflow of rivers for consumptive use;
                    5. Increased pollutant loading related to all of the above factors, and exacerbated by the naturally slow
                    flushing rate of the bay.
                    6. Alteration of water quality and habitat in tidal streams.
                    7. Boat prop scarring of seagrass beds.

                    In the past 30 years, loss of coastal vegetation (primarily mangroves) and seagrasses in the bay system has
                    been substantial in terms of total acreage. Estimates of vegetative loss range from 50-80% for seagrass
                    and about 50% for mangroves. The overall importance of these losses is directly related to biological
                    integrity of the estuary since the wetlands vegetation (both submerged and emergent) serves as an
                    important food source, nursery ground and substrate habitat for many species of marine organisms. A
                    more recent trend, 1982-1990, shows a 10% increase in Tampa Bay.


                    In addition to the habitat destruction, Tampa Bay has also suffered from significant point and nonpoint
                    sources of pollution. Due to the ecological, economic and aesthetic importance of this waterbody and the
                    noted water quality degradation, Tampa Bay has become a major focus of local, regional and state actions
                    to reverse the negative trends. It has been legislatively designated as a priority SWIM waterbody, and a
                    knowledgeable advisory committee has been set up. Needed studies are occurring and restoration efforts
                    are ongoing.

                    Nonpoint source pollution is a serious problem in the bay system. With the shift from wetland and upland
                    vegetation to streets, lawns and buildings, the quality of runoff severely decreases while the quantity
                    increases. The bay also serves as a shipping channel to the port and is subject to oil and grease pollution,
                    sewage, and occasional ftiel and/or cargo spills. An extreme phosphorus and nitrogen loading source
                    appears to be the port itself, which serves as a loading and unloading facility for items such as fertilizers,
                    pesticides, concrete and oil. Spills and waste of these products can be washed into the bay water during
                    rains. Even a 0. 1% fertilizer product loss would make this the major nitrogen source to the bay.


                    In addition to the substantial habitat destruction and nonpoint pollution problems, several point source
                    dischargers affect the bay. The worst water quality problems are found in Hillsborough and McKay Bays.
                    This area receives 60 MGD (to be expanded to 90 MGD) of treated wastewater from Hooker's Point
                    advanced treatment plant, 1268 MGD of cooling and process water from the TECO Power Company, and,
                    several other small industrial discharges in this portion of the bay. These are detailed in the following
                    paragraphs.


                    The Hillsborough River enters the northern portion of the bay, and, while the lower river has no point
                    sources, it receives nutrient and toxins (found in sediments) loading from Tampa urban runoff. The
                    Alafia River, a particularly important source of nutrients to the bay, has extensive phosphate mining and
                    fertilizer production operations in its headwaters. A phosphate processor, Cargill, is located at the mouth
                    of the river. A 1987 release of about 14 million gallons of highly acidic process water burned hundreds of
                    acres of productive Tampa Bay habitat. Restoration of Tampa Bay at the mouth of the Alafia River is in
                    progress.


                    The smaller tributaries in Hillsborough Bay area also have problems. A 1985 intensive survey of Delaney
                    Creek indicated that there were frequent DO violations and nutrient problems. Discharge from Nitram, a
                    nitrogen fertilizer company, has historically been a problem, but is now in compliance. In the past the
                    creek may have received leachate or accidental spills from a battery splitting operation. That business has

                                                                                                                                          101









                   since been closed. The site is currently under hazardous waste cleanup enforcement. A domestic WWTP
                   discharge has been proposed for the creek.


                   PaIM River and Sixmile C        now components of the Tampa Bypass Canal, have nutrient, bacteria and

                   DO problems. The dischargers to these rgAches include phosphorus and nitrogen processors and the
                   Eastside WWTP (which discharges to Sixmile Creek via Harney Creek). The worst water quality
                   problems, however, appear to be, Caused by the historical pollutant loading and the current nonpoint runoff
                   entenng this small river system. It flows through a heavily developed portion of Tampa and has been
                   extensively ditched, channeled, and walled. The major Palm River problem appears to be nonpoint input
                   of nutrients at fertilizer loading terminals.


                   In summary, Hillsborough Bay suffers from the highest concentration of pollution sources in the Tampa
                   Bay system. It has historically had the worst water quality in the basin. However, there has been some
                   notable improvement since the, Hookers Point plant converted to advanced treatment in the early 1979.
                   There has also been a net improvement of the industrial discharges. However, continued vigilance of
                   O*Iwges and the abatement of runoff is required t9 maintaip or imprQvc conditions in Hillsborough Bay.

                   Alligator Creek has high nutrient concentrations; and finally, the Cross Bayou Canal has nutrient,
                   bacteria and DO problems. Nlany of the thew problems are caused by the numerous, small WWTPs
                   located in Hillsbprough County operating under temporary permits (TOP). The treatment processes of
                   many of these facilities are inadequate to meet required treatment levels. There was a legislative bill
                   passed in 1987 requiring all dopiestif. dischargers to Tampa and Sarasota Bays to attain advanced
                   treatment st4ndards. This condition is still far from being satisfied. The bill was somewhat controversial

                   no longer dischorge to Cross Bayou Canal. Pinellas County has initiated a monitoring effort on that
                   waterbody. Nonpoint sources are still a problem for the entire drainage area. Tampa Bay proper exhibits
                   better water quality than Old Tampa Bay or Hillsborough Bay because it has greater mixing and dilution
                   with the Gulf of Mexico waters and less concentrated pollution sources. Development is fairly intense
                   along its shoreline, and there are both domestic and industrial discharges. Cockroach Bay, located on the
                   east side of Tampa Bay, has been downgraded from go( A to poor water quality. It is affected by septic
                   tanks and the lower part of Cockroach Bay has heavy agricultural impacts.


                   Because of its close connection to the Gulf, Terra Ceia Bay has very good water quality. Development
                   around this bay threatens it with increased runoff and mangrove cutting; although there have been some
                   enforcement cases which will hopefully deter the latter. The Pinellas County portion of Tampa Bay is also
                   designated as an OFW to protect it from further degradation; however, under current law, many of the
                   existing discharges to the bay will be allowed to continue operating. The Intergovernmental Program
                   Section of DEP (formerly Coastal Zone Management) has been conducting sediment metals surveys of
                   Poo areas and also some "ambient" sites within estuaries. Seven different metals were measured. The
                   Tampa Bay results show mctals enrichment (particularly lead, zinc and cadmium) in sediment throughout
                   much of Hillsborough Bay and associated with navigation channels. Another "hot spot" for metals
                   pprichment was the Port of St. Petersburg. Radium and radon levels are high in the bay; in fact, studies
                   from the University of South Florida found them to be the highest of any Gulf Coast continental shelf

                                                                                                                                        102











                   area. The suspected source is the Alafia River from the mining activities there or perhaps leachate from
                   fissures under nearby gypsum stacks.


                   The National Ocean Survey (NOS) has completed a study of fishes and sediments in the bay for toxin
                   problems, In addition, USF has performed sediment sampling for metals. NOS has also completed a tidal
                   circulation study. Information from that study will be used to correct tide tables and predict currents more
                   accurately and also provide information to aid in hydrologic/eutrophication modeling of the bay.


                   In August 1990, Pinellas County initiated a water resources monitoring network. The stated goals of that
                   program are the development of specific watershed management plans for the drainage basins throughout
                   the county. The county is preparing management plans for Allen's Creek, Lake Tarpon, and Lake
                   Seminole.


                   In summary, Tampa Bay has suffered impacts from welland and seagrass destruction and coastline
                   alteration; severe stormwater pollution from residential and commercial sources; dredging and harbor
                   activities; litter; fertilizer, food processing, and other industrial discharges; and a heavy load of domestic
                   wastewater from power and sewage treatment utilities. The bay has extremely high phosphorus levels and
                   is nitrogen limited. Recent trends in water quality show improving conditions in Hillsborough Bay.
                   SWIM legislation has targeted Tampa Bay as one of the waterbodies to receive funding for restoration and
                   other management projects. The plan encompasses stormwater control, habitat restoration and increased
                   environmental monitoring and assessment.

                     * The Withlacoochee River was designated an OFW.
                     * A compromise plan to turn the Cross Florida Barge Canal into a 40,000
                       acre "greenway corridor" for recreation and conservation apparently
                       was worked out on Capitol Hill.
                     * A major fish kill was reported on Lake Rousseau. The combined effects
                       of herbicide spraying for aquatic weed control, overcast skies, and
                       low dissolved oxygen levels resulted in the death of 45,000 fish.

                 Ecolopical Characterization


                 Originating from the Green Swamp near the junction of Lake and Polk Counties, the Withlacoochee River
                 flows generally west and north for approximately 157 miles and drains 2,090 square miles of West


                                                                                                                               113








                 Central Florida before discharging to the Gulf of Mexico. The average flow of the Withlacoochec River is
                 estimated to be 1,800 cfs at the mouth of the river. A major portion of the flow is contributed by the
                 Floridan Aquifer. During the course of its long journey, the Withlacoochee crosses many habitats. From
                 its cypress swamp headwaters, it passes through pine and hardwood forests, palmetto hammocks, small
                 lakes and ponds and is hydrologically connected to adjacent Tsala-Apopka Lake. This "lake", covering
                 about 30 square miles, is really more like a large grassy marsh with a series of pools of open water. It is
                 sometimes referred to as the miniature Everglades. Downstream of Tsala-Apopka, the Withlacoochee is
                 impounded near Inglis to form Lake Rousseau. A remnant of the Cross Florida Barge Canal connects
                 Lake Rousseau to the Gulf through locks. From the dani, the river flows another I I miles to the saltmarsh
                 estuary fringing the Gulf.


                 Along its course the river receives considerable input from the Floridan Aquifer. Blue Run, a 6 mile long
                 river flowing from the largest of the springs, Rainbow Spring, enters near the head of Lake Rousseau.
                 Lake Panasoflkee is a spring-fed lake connected to the river upstream of Tsala-Apopka.


                 Land use in the Withlacoochee River basin consists primarily of silviculture and citrus groves in the upper
                 reaches of the river basin. The river flows through the Withlacoochee State Forest in the middle reaches.
                 There is also considerable drainage from wetlands. The banks of Lake Rousseau and the downstream
                 Withlacoochee have moderate residential development. There are no major cities along the entire corridor
                 of the river; however, just west of Tsala-Apopka Lake there is considerable residential development and
                 the City of Inverness. The Southwest Florida Water Management District has bought large holdings all
                 along the river, and is especially trying to safeguard the Tsala-Apopka and Panasoflkee areas and the
                 headwater region in the Green Swamp.


                 AnthroppRenic Impacts


                 Water quality in this basin is very good, especially along the river itself, where all monitored reaches are
                 meeting their designated use. The spring fed Blue Run (also called Rainbow River) has excellent water
                 quality and is designated as an Outstanding Florida Water and a SWIM preservation waterbody. Much of
                 the Withlacoochee River has periods of low DO during high flows due to swampland drainage.


                 There are few water quality problems in the basin, but the Nonpoint Assessment rates most of the
                 waterbodies: as threatened. In the upper basin, the Dade City Canal, which is affected by agricWtural
                 runoff and orange processing companies, loosely connects to the river via wetlands. The upper stretches
                 of Juinper Creek may be affected by agriculture and citrus operations at Center Hill. The Little
                 Withlacoochee River is also threatened by agriculture, silviculture and, near its confluence with the
                 Withlacoochee, residential and septic tank runoff. Lake Panasoflkee is a spring fed lake and has good to
                 fair water quality. There are some weed problems and there is some threat from shoreline development
                 and septic tank leachate.


                 In the lower basin, Lake Rousseau experiences excessive aquatic weed growth, particularly hydrilla. The
                 river is periodically sprayed for aquatic weed control. Construction activities, shoreline alterations (such
                 as finger canals and docks) and failing septic tanks, contribute sediments, nutrients and bacteria to the
                 lake. The reservoir has fair water quality. The artificial maintenance of constant water levels in the lake
                 may also affect water quality. Drawdown of the lake as a way of improving water quality has been
                 recommended by the SWFWMD and by the FGFWFC, but it would require modifying the water control
