PREFACE

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.

0 Reeional 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. * 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 Nonvoint Source Oualitative Surny - 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. 0 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 Aerbster 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 Mke 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.

4 of 115 2/10/2012 10:08 AMEXECUTIVE SUMMARY/OVERVIEW

The 305(b) Technical Report provides useful surface water quality related information in a fonnat 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 Qualily 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 estuaries with fewer miles in the "meets use" category and more miles in the "does not meet use" category. Inter6 stingly enough, this year's lake assessment brought in many more small lakes with good overall quality, however, Florida's largest lakes (Lake Okeechobee and Lake George) still overwhelm the State average with their large mileages of fair to poor quality.

A

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:

I . 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.

8 of 115 2/10/2012 10:08 AMPollution 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.

5. Hydrological Modifications. This can take the form of damming running waters, 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 Miami 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 Biscayne Bay are hundreds of times higher than State criteria. Efforts are being made by the City of Miami and Dade County to correct these problems.

9 of 115 2/10/2012 10:08 AMNorthwest Region Basin-by-Basin Evaluation of Water Quality

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

In general, rivers in this region have good water quality, with a number of near pristine waterbodies. The major pollution sources in the area include agricultural, silvicultural, and construction runoff. Additionally, several, low volume WWTPs, especially in rural areas, are overloaded and/or poorly operating. Rapid coastal development threatens bays and lagoon waters. Finally, some high volume point source discharges, particularly from pulp and paper mills, adversely affect water quality.

The Perdido Bay basin has water quality problems in two major areas: Elevenmile Creek and Bayou Marcus Creek. Champion Paper Company discharges into Elevenmile Creek. Dioxin contamination is a concern as fish taken from the creek have had tissue levels of dioxin ranging from 8.1 to 2S.7 parts-per-trillion. The EPA recommended maximum level is 7 parts-per-trillion. Bayou Marcus Creek receives urban runoff and discharge from a waste treatment facility. The bay is threatened and partially degraded due to these point and nonpoint pollution sources. Perdido River has good water quality except for the area near its mouth that is affected by poorer quality bay waters.

The Escambia, Blackwater, and Yellow Rivers all drain into Pensacola Bay. They generally have good water quality except for localized areas downstream of point sources. In the Escambia River, these areas are in the northernmost reaches, with mostly domestic dischargers, and in the southernmost reaches where there are industrial dischargers. Trammel Creek in the Yellow River basin shows degraded conditions due to domestic discharge. That WWTP has a history of discharge violations. One of the more recent resulted in a large fish kill. The WWTP discharge (from the City of Crestview) has been removed from Trammel creek and routed to an upland site. Though the general water quality of Escambia, Blackwater, Yellow, and Perdido Rivers appears to be good, all four rivers have a mercury problem. High enough concentrations of mercury were found in tissue of largemouth bass to warrant issuing limited consumption advisories. The Pensacola Bay basin has water quality problems associated with urbanization around the City of Pensacola. The western bay receives the bulk of the treated wastewater and urban runoff, while Escambia Bay has industrial discharges. Fish kills have been a persistent problem in both Pensacola and Escambia Bays and their tributary bayous. Although the Choctawhatchee River generally has good water quality, it has a moderate degree of impact from agricultural runoff (turbidity, nutrients, pesticides, etc.). Additionally, several of the tributary systems within the basin have problems associated with domestic or industrial discharge. Alligator, Holmes, and Camp Branch Creeks receive discharge from Chipley, Graceville, and Bonifay WWTPs, Xiii

respectively. West Sandy Creek and Bruce Creek, in the western basin, receive discharge from DeFuniak Springs WWTP and the Showell Farm poultry processing plant, respectively. Most of these small treatment plants have recently been upgraded or are in the process of being upgraded through Consent Orders. Choctawhatchee Bay has good water quality, but is threatened by development of its watershed. Of particular concern are spray field and/or urban runoff from developed areas at Ft. Walton Beach and Destin.

St. Andrews Bay has fairly good water quality except for an area around a paper mill discharge. Most of the rest of the basin has good water quality except Beatty Bayou. High concentrations of lead, mercury, DDT, chlordane, PCB's, and polycyclic aromatic hydrocarbons have been found in sediments in Watson Bayou. Also, Deer Point Lake, the drinking water source for Panama City, has nutrient and aquatic weed problems. Both Econfina Creek and Deer Point Lake have largemouth bass contaminated with mercury resulting in fish limited consumption advisories. St. Josephs Bay has excellent water quality except for an area around its paper mill discharge.

The Chipola River has generally good water quality. Localized threats to the river include high nitrates, BOD, and siltation from agricultural and silviculture nonpoint sources. A Basin Assessment found that the river is severely phosphorus limited due to high levels of nitrogen. A tributary to Chipola River and Dry Creek is a Superfund site because of contamination from a battery reclaiming industry and is currently undergoing a cleanup.

The Apalachicola River basin has a mix of good and problem water quality areas. Scipio Creek, at the mouth of the river, is impaired by shrimping and marina activities and historic wastewater loading. The WWTP which formerly discharged to Scipio Creek has been converted to wetlands discharge. The City of Blountstown WWTP discharges to Sutton Creek. That plant has had past problems and is presently under a Consent Order. Apalachicola Bay has very good water quality and supports Florida's largest commercial oyster fishery. Though within this basin there are localized problems due to nonpoint source pollution from fish houses and marinas. The New River basin which drains into the eastern end of Apalachicola Bay has very good water quality. Little of this basin's area has been developed. At the eastern end of Apalachicola Bay is St. George Sound. In general the Sound has good water quality with exception of the area near Carrabelle. The City previously discharged primary treated wastewater, but has recently made significant upgrades in its treatment.

The upper Ochlockonee River has turbidity and nutrient problems primarily from agricultural runoff and out-of-state point sources. Siltation has resulted in a depressed macroinvertebrate community, and as a consequence, a fishery decline. The lower river, Lake Talquin and the Sopchoppy River maintain good water quality. Fish consumption advisories that recommend limited consumption have been issued for both Lake Talquin and the Ochlockonee River and may soon be issued for the Sopchoppy River. Telogia Creek, a tributary to the Ochlockonee, has nutrient and DO problems in its upper reaches as a result of runoff from the Gretna WWTP spray. fields. Court action has been taken against the City of Gretna to remove all discharges from Telogia Creek. Xiv

10 of 115 2/10/2012 10:08 AMThe St. Marks, Wakulla, and Aucilla Rivers have excellent water quality except for a small stretch in the lower St. Marks that has oil polluted sediments from oil spills, historic Seminole Asphalt discharge and marina activities. Munson Slough and Lake Munson in Tallahassee have pollution problems from past domestic discharges (now routed to spray irrigation) and current stormwater runoff. Lake Munson has shown marked improvement in water quality since the diversion of the WWTP discharge.

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 Secchi depth. Screening levels for 19 water quality parameters were also used to determine the quality of Florida lakes, estuaries and streams.

Specific information on each of the procedures is described in the following sections.

Watershed as the Assessment Unit

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

The major waterbody within each watershed was identified and named. Usually each watershed encompassed one major or one minor named waterbody (similar to the 1992 reach structure). The length of each stream waterbody and the area of lake and estuary waterbodies is essential information. The length of stream waterbodies was determined by GIS measurements of the RF3 trace ( or assigned a length of 5 miles if no RF3 trace was available). The area of lake and estuary waterbodies was determined with crude GIS aerial measurement techniques (if estuary waterbodies had no RF3 traces, their area was set to 5 square miles and unknown lake waterbodies were assigned an area of 1 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

13 of 115 2/10/2012 10:08 AMcodes 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 WQ1 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 watei 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). ABOD 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. Nfissing water quality parameters and missing water quality categories are ignored in the final calculation. Therefore, the final WQI is based on an average of anywhere from I to 6 water quality index categories. Table 5 shows an example calculation of the 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 WQ1 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

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

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

Trophic State Index Procedure

The Trophic State Index procedure provides an effective method of classifying lakes based on the lake's chlorophyll, Secchi depth, nitrogen and phosphorus concentrations. The index was developed in 1982 in response to the EPA Clean Lakes Program and is documented in the Classification of Florida Lakes Report by the University of Florida, Department of Environmental Engineering Sciences. This index remains unchanged from the 1988 305(b) report.
The index is based on a trophic classification scheme developed in 1977 by R.E. Carlson. It relies on three trophic indicators to describe the trophic status of a lake. The goal was to have each indicator relate to algal biomass such that a 10 unit change in the index would represent a doubling or halving of algal biomass. Carlson developed indices based on Secchi disc transparency, chlorophyll concentration and total phosphorus concentration. The Florida Trophic State Index (TSI) is based on the same rationale, but also includes total nitrogen concentration as a fourth index. Criteria were developed for Florida lakes from a regression analysis of data on 313 Florida lakes. The desirable upper limit for the index is set at 20 ug/1 chlorophyll which corresponds to an index of 60. Doubling the chlorophyll concentration to 40 ug/1 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 trend information from eight water quality parameters (bacteria, turbidity, total suspended solids, BOD, dissolved oxygen, Secchi depth, nitrogen and phosphorus) plus the overall water quality index. Lake and estuary trend analysis focused on four trophic state parameters (chlorophyll, Secchi depth, nitrogen and phosphorus) plus the trophic state index.

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

Toxic Pollutant Assessment

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

Nonpoint Source Assessment

An extensive assessment of nonpoint source impacts on Florida!s waters was conducted in

The respondents (approximately 150 agencies and 350-400 participants) to the questionnaire identified nonpoint sources of pollution, environmental pollution symptoms (fish kills, algal blooms, etc.) pollutants and miscellaneous comments. The assessment has been updated in 1994. The 1994 nonpoint source assessment was performed more efficiently than the 1988 version due largely to the use of GIS technology for compiling and displaying the data, and also advancements in the questionnaire methodology. Scannable forms were used eliminating the need to key punch data and integration with the 305b report was much improved.

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

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

Impairment rating categories used were as follows:

I . Good (meets designated use). All surface waters in the watershed are supporting their use classification with no evidence of nonpoint source problems. 2. Threatened (meets designated use). All surface waters in the watershed are attaining their use classification, but in the absence of any future management activities, it is suspected that within five years at least some of the surface waters in the watershed will not support their designated use. 3. Fair (partially meets designated use). Some, but not all, surface waters in the watershed are not supporting their designated use. 4. Poor (does not meet use). All 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 waterbodies, release of radioactive materials to groundwater, discharge of acid mine drainage and depletion of water supplies in aquifers.

15

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 CN Construction site runoff IM Hydrologic Modification OT Other nonpoint source 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. 

# Florida water quality assessment 1994 305 (b) main report http://www.gpo.gov/fdsys/pkg/CZIC-td224-f6-h36-1994-v-4/html/CZIC-...

20 of 115 2/10/2012 10:08 AM2. 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.

7. Debris. This category includes trash ranging from Styrofbam 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:

I . 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.

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 NP S survey provided all the information on sources of pollution (e.g. urban or construction runoff) and part of the information on causes and symptoms of pollution. Integrating the information from the quantitative (STORET) analysis and the qualitative NPS survey was not easy, but many additional watersheds were assessed based on the results of the integration. In the future, the two techniques should blend together much better through increased coordination of efforts.

illnesses after eating oysters from the Bay. Center for Disease Control and Prevention reported on 6/24/94 that routine testing for bacteria in oyster beds apparently is insufficient to prevent food poisoning after finding despite testing just days prior to oyster harvesting in Apalachicola Bay 45 people came down with food poisoning. Ten people were hospitalized for more than a day.

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

Ecological Characterization

The Apalachicola Bay Basin encompasses approximately 200 square imiles of estuary area including St. Vincent Sound, East Bay, Apalachicola bay and St. George Sound. The bay system is the terminus of a 20,000 square mile basin which extends to a point north of Atlanta, Georgia. The, Bay is defined by the barrier islands: St. George Island,. Cape St. George and St. Vincent Island. Communication with the Gulf of Mexico is through several natural channels: East Pass, West Pass and'Indian Pass, and through Sikes Cut, a U. S. Army Corps of Engineers (COE) maintained channel between Cape St. George and St. George Island. The major inflow into the bay is the Apalachicola River with an average flow of 25,000 cfs varying seasonally from less than 15,000 to greater than 100,000cfs. The basin is primarily the bay water, but also encompasses drainage from the City of Apalachicola and the barrier islands.

The drainage is sparsely developed. The north shore is lined by individual residences, forestry lands and three small urban areas. Apalachicola, the largest city in the basin, is near the mouth of the river. St. George Island is developed for residential use, mostly in the middle third of the island. These residences, hotels and small businesses use septic tanks. Other barrier islands are undeveloped. A bridge crosses the Bay from East Point to St. George Island.
Productivity in Apalachicola Bay is based on the large amount of detritus entering the bay via the Apalachicola River. The bay waters are generally more turbid and less saline than many of Florida's other estuaries. However, away from the mouth of the river, particularly in St. George Sound, waters are clearer and support more seagrasses. The bay system supports a very productive shrimp fishery and is famous for its oysters.

The entire bay as well as the Apalachicola River has been declared an Outstanding Florida Water. It is also the largest National Estuarine Research Reserve. The bay area is an Area of Critical State Concern which requires more intensive regulation of planning and development by the State. The Bay is a State Aquatic Preserve and a priority SWIM waterbody. UNESCO has designated the Bay as an International Biosphere Reserve. Clearly, the State and nation recognize its value.

23 of 115 2/10/2012 10:08 AMAnthropogenic Impacts

The Bay has good water quality. The most serious threats to the water quality in the bay are associated with nonpoint sources from the more urbanized areas in the basin. In the northern part of the bay, untreated stonnwater runoff from the City of Apalachicola and nearby fish-houses have had a localized impact on the bay. The City of Apalachicola must upgrade the domestic WWTP to current standards for wetland discharge. Problems associated with fish-houses include high BOD from fishing wastes and pollutants due to boat traffic, docking and fueling. These problems are also found in Eastpoint which is covered in the New River Basin.

The Bay is often closed to shellfishing due to increased bacteria counts, usually associated with rainfall and high flows from the Apalachicola River.

In the southern Bay area, there has been rapid development of St. George Island, and there is concern over septic tank leachate into the bay. The Department of Health and Rehabilitative Services conducted a 1986 study of septic tanks on the island and found that 23% of the 724 tanks were failing, and that many of them were poorly located with respect to water tables and the required 50-foot setback. A centralized wastewater treatment facility was proposed for construction, but both its design and payment responsibility were controversial. The compromise is a requirement that all new development use aerobic treatment systems and a program to require upgrading of existing systems. There is a boat basin on the island that receives runoff from a shopping area and wastes associated with the mooring, fueling, and off-loading activities of oyster boats. A permit to build a 150 wet slip/120 dry slip marina near Sikes Cut is currently being assessed.

Other man-induced threats to the bay are over-fishing and dredging activities by the COE. Several controversies surround both issues. Maintenance channels within the bay and the river have temporary turbidity effects in the water column and have more lasting effects on the biological and sediment quality of the bay due to siltation.

Ruppi , a submersed aquatic plant that serves as a nursery area for fish and wildlife was noted returning just outside the river mouth after dredging 16 years earlier. The dredged channel between the river and Green Point (watershed #2) with shoreline seafood processing facilities experienced low dissolved oxygen concentrations and a minor fishkill last summer.

27 of 115 2/10/2012 10:08 AMThe SWIM Plan for the Apalachicola Bay and River System has been approved. A controversial plan by the Corps of Engineers to divert more water from the upper basin for Atlanta and a water control plan for the reservoir

system has been dropped. In exchange, the states of Florida and Alabama have agreed to suspend a year-old lawsuit over water supply and the water control plan. The Corps of Engineers and the states have started a multi-million dollar, 3-year study of the water resource needs and demands of the tri-river system. Florida, Georgia and Alabama will each contribute $250,000 per year to the study.

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

Ecological Characterization

The Apalachicola River is formed by the confluence of the Flint and Chattahoochee Rivers at Lake Seminole. In Florida, the Apalachicola River flows 107 miles southward from the Jim Woodruff Dam (near the City of Chattahoochee) to the Apalachicola Bay at Apalachicola. The entire Apalachicola-Chattahoochee-Flint drainage area encompasses over 20,000 square miles with only 12% in Florida. The Apalachicola, with an average flow of about 25,000 cfs, has a greater flow than any other Florida river.

Flow varies considerably with the season, ranging from about 12,000 cfs in the fall to over 100,000 cfs in the winter and early spring. Flow variability is important to the ecological function of the river. During high flows, the river overflows its banks into its extensive floodplain (1-5 miles wide). The detritus carried by the river, particularly during flooding, provides the primary food source for Apalachicola Bay. The bay supports major fishing and shellfishing industries.

The Apalachicola basin is unique in Florida since it is the only river that has its headwaters in the Appalachian Piedmont outside the coastal plain. Consequently, the area contains numerous Appalachian-originated species found nowhere else in Florida. Additionally, the high bluffs, deep ravines and seepage streams (steepheads) provide the basin with both beautiful scenery and special habitat. This area has the highest floral and faunal diversity in the State.

Florida's portion of the basin is sparsely populated, and much of the adjacent land is in public ownership. Land use in the upper Apalachicola (above the Chipola River confluence) consists primarily of forestry and agriculture. In the lower Apalachicola, land is mostly forested or wetlands. The largest cities in this basin are Chattahoochee and Apalachicola.

Anthropogenic Impacts

Water quality in the majority of the Apalachicola River Basin is very good. The River is, together with the Bay, an Outstanding Florida Water and a National Estuarine Research Reserve. In fact, biological samples from some of the tributaries to the river indicate near

25

pristine conditions. These tributaries are Rock Creek, Flat Creek, Crooked Creek (and Sweetwater Creek, not shown on map). One tributary in the upper basin (Lower Ocheesee Creek) had severe erosion/siltation problems from unpaved roads and farm run- off.

The river and bay are dredged and maintained for barge navigation by the U.S. Army Corps of Engineers. It is one of the Corps'most expensive (per ton-mile) projects in the country. In addition to the sporadic disruption by the dredges, the tug and barge traffic also stirs up the sediments. Barge cargo primarily consists of gravel, fertilizer, and oil. Prior to entering Florida, the river system receives numerous discharges ftom Atlanta and other urbanized areas (textile mills, wastewater treatment plants, steam power plants, and a nuclear power plant) and extensive runoff from the agricultural areas of Alabama and Georgia. Sediment and water quality pollution are somewhat contained at the Jim Woodruff Dam.

In addition to upstream point sources, Florida has a few dischargers. Both Florida State Hospital and the City of Chattahoochee WWTP discharge to Mosquito Creek. Fifth year bioassessment for City of Chattahoochee WWTP was conducted in December 1993. Results did not find biological impairment in Mosquito Creek due to the City WWTP discharge. The findings did suggest nutrient enrichment is occurring in Mosquito Creek from point source discharges. Algal growth potential results from the Florida State Hospital WWTP and the Chattahoochee WW'1? are a cause for concern. Florida State Hospital will be evaluated in October 1994. South Mosquito Creek at C-379 B has severe stream habitation alteration due to impounding resulting in cattail replacing native vegetation. The Scholtz Steam Power Plant lies below Sneads and discharges into the Apalachicola River. The City of Blountstown WWTP discharges to Sutton Creek which 

# Florida water quality assessment 1994 305 (b) main report http://www.gpo.gov/fdsys/pkg/CZIC-td224-f6-h36-1994-v-4/html/CZIC-...

28 of 115 2/10/2012 10:08 AMhas had problems in the past. The City of Blountstown has been informed that alternatives to the current method of effluent disposal are necessary. They must either upgrade to AWT or go to upland disposal. DEP awaits their decision on which direction they will proceed. Finally, the Apalachicola City WWTP, which previously discharged to Scipio Creek has been upgraded and now discharges to wetlands, however the current discharge to wetlands is not adequate. They are currently operating under a Final Order to either further upgrade the facility or remove their discharge from their present location. Scipio Creek is also subject to pollution from considerable shrimp and fishing boat traffic and a marina. The marina is currently making renovations including a pump-out facility. These upgrades should help to improve the conditions in this creek.

An Executive Coordinating Committee for the Apalachicola-Chattahoochee-Flint (ACF) Basin was formed by a 1992 Memorandum of Agreement signed by the states of Florida, Alabama and Georgia and the U.S. Army Corps of Engineers. Its purpose is the oversight of the comprehensive study for the ACF and Alabama-Coosa-Tallapoosa (ACT) river basins, the development of basinwide management plans and to discuss and attempt to resolve interstate disputes until a permanent coordination mechanism is in place.

Ecological Characterization

The Blackwater River originates north of Bradley, Alabama, and flows approximately 58 miles prior to entering Blackwater Bay in northwestern Florida. The basin drains about 860 square miles, mostly in Santa Rosa and Okaloosa Counties. Average discharge of the Blackwater River is approximately 400 cfs at a location 35 miles upstream of the mouth. Major tributaries of the Blackwater River include Juniper Creek, Big Coldwater Creek, and Pond Creek. The basin's rivers are of the blackwater type, stained reddish-brown by tannic acids from swamp and forest drainage. The rivers also receive considerable groundwater flow from the sand and gravel aquifer. In general, the rivers are swift and shallow and characterized by beautiful white sand bars. The Blackwater River flows through Blackwater State Forest and is a favorite of canoeists.

Land use in the basin is primarily state forest land, silviculture and some agriculture. There are no major urban areas in the basin.

Anthropogenic Impacts

Overall water quality in this basin is excellent, and the Blackwater River is designated an Outstanding Florida Water.

The US Navy Whiting Field WWTP was issued a no discharge wasteload allocation in

33 of 115 2/10/2012 10:08 AMMarch, 1994 due to water quality violations in Clear Creek discovered during the 5th year survey conducted in October 1993. The Navy is currently studying methods for upland disposal. A 5th year survey for the City of Milton WWTP is scheduled for August 1994.

Ongoing gas pipeline construction across the District is causing turbidity, sedimentation, and habitat destruction at crossing locations in the basin. Many subdivisions have been constructed in the Pond Creek watershed between Pace and Chumuckla in the past couple of years with resuiting nonpoint source problems creating flooding, erosion, and sedimentation. The University of Florida Agricultural Research Center located in Pond Creek headwaters had dumped waste pesticides in the past and sludge from Pensacola wastewater treatment facilities was experimentally land applied without DEP monitoring.

Ecological Characterization

The Chattahoochee River Basin in Florida consists of a short stem of the Chattahoochee River itself and Lake Seminole which is an impoundment at the confluence of the Chattahoochee and Flint Rivers. Both rivers have extensive drainages in the coastal plains and are considered alluvial in nature. Intense agricultural usage in these basins contribute heavily to the sediment load delivered to Lake Seminole and give these rivers a cloudy, reddish-brown look, atypical of most Florida streams.

41

Lake Seminole is about 40-45 square miles in surface area of which 18 are in Florida. Typical of many impoundments, the lake has a dendritic pattern with hundreds of coves. It is heavily fished and supports several marinas and fish camps. There is also a state park on the lake that is very active in summer months. There are no urban areas draining to the lake, but there are several small developments and houses along some of the banks. However, most of the shoreline has not been cleared.

Anthropogenic Impacts

The major impacts to the water quality of the Chattahoochee River are from upstream discharges and agricultural runoff. Heavy "red clay" siltation is very apparent in the Florida reach of the river, especially after rains. This is one of the few rivers in Florida that experiences the sediment/fami/chemical type of agricultural nonpoint pollution typical of most of the southeastern states.

The U.S. Army Corps of Engineers maintains a dredged channel and locks for passage of commercial barge traffic through the Chattahoochee River, Jim Woodruff Dam and the Apalachicola River. The Corps manages lake levels and water delivery throughout the system.
The Jim Woodruff Dam was built to provide hydroelectric power and some degree of water regulation. However, it is basically a "run of the river" dam with little storage capacity, especially at high flows. The sediment and organic detritus, located in the deeper portions of the lake near the dam, have a poor macroinvertebrate community, probably due to low oxygen and perhaps some metals in the sediments. The lake had some aquatic weed problems, and the Corps annually treated certain areas with herbicides (commonly Rodeo, Sonar, and Aquatol K).
Lake Seminole now has a serious aquatic weed problem and a proposed water quality monitoring for the lake is to be funded by EPA and coordinated by DER

Ecological Characterization

The Chipola River is one of Florida!s most unusual and diverse waterways and has an Outstanding Florida Water designation. From its spring-fed sources in southern Alabama,

48

it flows about 110 miles and is the major tributary of the Apalachicola River. The drainage basin is about 1,025 square miles, and the average flow is 1,500 cfs.

The river originates in the Marianna Highlands from several springs and the confluence, of Marshall and Cowarts Creeks. Typical of many spring-fed rivers, it carries a small sediment load, is low in color, and has a relatively steady flow. The upper portion of the basin has a diverse terrain with bluffs, sand hills, swamps, sinks, and both terrestrial and underwater caves. The river goes underground for a short distance near Marianna.

Several spring-runs and some surface drainage tributaries join the Chipola after it emerges. However, several miles below Fourmile Creek the river flows out of the limestone highlands and empties into a low swampy area. Here, the tributary inflow is mostly blackwater.

Old levees of the Apalachicola River naturally impound the lower Chipola forming Dead Lake. A dam built in the 1960s to enhance the natural impoundment was recently removed. At the lower end of the lake, the U.S. Army Corps of Engineers maintains the Chipola Cut-off, a once natural diversion, that now captures about one-fourth of the Apalachicola River's flow. From here, the two rivers follow a roughly parallel course until they meet about eight map-miles downstream.

43 of 115 2/10/2012 10:08 AMExceptional water quality and habitat diversity support rich wildlife communities. The river is heavily used for canoeing, boating, tubing and fishing. There are several recreation areas and fish camps.

There are only two urban areas in the basin (Marianna and Wewahitchka), both small. However, because most of the basin lies in the highland area, there is more intensive.land use than the more typical swampland drainage of North Florida rivers. The upper basin has agricultural rangeland and silviculture areas. The lower basin is mostly wetlands and silviculture.

Anthropogenic Impacts

Water quality in the Chipola River basin generally appears to be good; however, only about one-half of the stream reach mileage has been sampled for water quality. A Basin Assessment of the Chipola River was performed by Northwest District DEP, and two WLA studies of point sources have been performed. The upper reaches have some localized areas of relatively high nitrates, BOD and siltation predominantly from agricultural and silviculture nonpoint sources, but the river retains its "good" WQI rating. The river tends to have relatively high levels of nitrogen compared to surrounding waterbodies, but low phosphorus levels. A recent algal assay also indicates the river is severely phosphorus limited. Any increase in phosphorus loading could greatly enhance algal growth of the river and downstream lake.

49

The middle reaches have several small WWTPs. The basin assessment found high coliform counts below the Marianna WWTP, and reported a trend of increasing nitrate levels in the river over the last ten years. These reaches also have seasonally high nutrient and chlorophyll values, and are considered to have fair to good water quality. The Basin Assessment also indicates there have been aquatic weed and eutrophication problems in Dead Lake due to agricultural runoff. Macroinvertebrate diversity is reported to be seasonally low downstream of the lake. The Dead Lake dam has recently been opened to allow natural stream flow. The water level of Dead Lake naturally fluctuates depending on flow in the Apalachicola River. The river water level has been high since the removal of the dam, so little difference in the lake levels has been noted. It is not certain how the change will affect the lower Chipola and Apalachicola Rivers. The Dry Creek, area has heavy metal contamination from a battery salvage operation. This contamination is now being cleaned up through the use of Federal funds. The Basin Assessment also found high mercury levels below Marianna.

Fifth year bioassessments for Arrowhead Campground V;WTP and City of Marianna WWTP are scheduled for September and November 1994. The Holiday Inn of Marianna WWTP, traditionally a problem source, has been connected to the City V;WTP.

The Spring Creek (watershed #27, south of Campbellton) stream channel was moved and culverted (habitat destruction) along with other dredge and fill impacts from construction on US Highway 23 1.

Bridge Creek at SR 71 within a mile of 1-10 had to be abandoned as an ecoregion monitoring site because of clear cutting of the stream side climax forest and a newly permitted industrial site on the north bank.

Ecoloizical Characterization

Choctawhatchee Bay basin encompasses 699 square miles with the bay itself covering 129 square miles. The bay has little communication with the Gulf of Mexico, with only one inlet, East Pass, on the western end of the bay. Freshwater inputs are the Choctawhatchee River, at 7,000 cfs, entering at the easterrunost end of the bay, and several small creeks entering the bayous along the northern shore of the bay.

Development along the north and west is sparse, with Eglin Air Force Base occupying most of the northern drainage. The City of Ft. Walton Beach is on the eastern shore, and Destin is situated at East Pass. Residential, hotel and condominium development is occurring rapidly all along the peninsula that forms the southern boundary of the bay. An endangered fish species, the Okaloosa Darter, is found in the streams draining into Boggy and Rocky Bayous.
Anthropogenic Impacts

Historically water quality in this basin has been good. However, there have been several problem areas associated with rapid development occurring along the coast. In the 1970s,

56

treated wastewater effluents caused eutrophication, fish kills and grass bed die-offs in portions'ofthe-bay. The WV*7TPs have since been converted wspray irrigation discharge. A basin assessment conducted by the DEP Northwest District in 1984 indicated that water quality did improve once the WWTPs were upgraded.

Recently, however, water quality in the bay ig again being degraded due to the continuing development of the watershed area. The nonpoint pollution sources associated with this development include highway runoff, ditching and draining of wetlands and surficial water table seepage from package plant perc-ponds and WWTP spayfields. In particular, the poorly circulating water of Old Pass Lagoon at Destin, Florida has shown high levels,of eutrophication and fish kills in the past. Local education programs and ordinances along with increased emphasis on stormwater treatment appear to be:-reversing. the pollution trend. Fish kills have not been reported in recent years. A Gulf-*to-Lagoon pipeline and pump has been partially constructed by the Northwest Florida Water Management District to facilitate lagoon flushing. In April 1994, Dissolved oxygen violations were found during flush, pump operations in Old Pass Lagoon (Destin Harbor) and'Holiday Isle canals. Several bayous that discharge into the Bay have had and continue to have water quality problems. Also, Dons Bayou near Ft. Walton has experienced a low grade, chronic fish kill from unknown sources. Recent studies indicate localized metals contamination in. sediments near urban areas. The NOAA National Status and Trends Program, which monitors trends of chemical contamination, found high concentrations of lead, silver, DDT, chlordane, PCB, and polycyclic aromatic hydrocarbons in sediment at Shirk Point, near the mouth of Boggy Bayou. Fish kills have also been reported in Jose Bayou in Destin, Jolly Bay at Black Creek and in LaGrange Bayou. The latter has a small shipyard located near Freeport.
Another major area of concern for the basin was a proposed bridge from White Point across the bay to Piney Point which- had been permitted. Potential sources of ecological damage include: destruction of grass beds, decreased circulation of bay waters, destruction of wetlands from Piney Point to the connecting highway, and construction associated turbidity. The bridge will also promote even faster growth in the area, further stressing the existing infrastructure.

An existing bridge across the bay is in service however, mitigation of seagrass nursery beds destroyed during construction has not yet suceeded.

Commercial fisherman report crab kills in the vicinity of Peach Creek at the mouth of the Intracoastal Waterway. Monitoring found low dissolved oxygen concentrations in Peach Creek and the stream had been historically channelized in a mistaken attempt at mosquito control. A new WWTP (Point Washington WWTP) near Peach Creek has been permitted for construction because of the area's increased development.

In lu Ems
A 100 year flood occurred on the Choctawhatchee River in the spring of 1990.

Ecological Characterization

The Choctawhatchee River originates in northern Alabama, entering Florida near the town of New Hope, and flows approximately 89 miles from the Florida-Alabama line to Choctawhatchee Bay. The Choctawhatchee River basin drains roughly 3,300 square miles of northwest Florida. The remainder of the 4,646 square miles of total drainage area is located in Alabama. The average flow of the Choctawhatchee River (21 miles upstream from the mouth) is estimated as 7,000 cfs.

The Choctawhatchee River is basically alluvial in nature, and carries a relatively high sediment load. It does, however, flow through limestone areas and has considerable spring input. Holmes Creek, with an average discharge of about 1,000 cfs, is mostly spring flow. Below Holmes Creek, near Ebro, spring flow can make up as much as a third of the main river's flow. There are also several acidic, blackwater creeks that drain into the river and its major tributaries. Therefore, the basin has all three major river types. The basin also has several lakes, mostly solution or sink depressions.

The basin is used mostly for agriculture and some silviculture. The lowerportion also has extensive wetlands. The upper portions of the river flow through steep banks and deposit large sand bars, while the lower river flattens out into a fairly wide (up to a mile) swampy floodplain. There are some developments along the river (mostly upper river and near the bay) but little urbanization. The major cities in the basin are located on the tributa nies. Much of the actual river corridor is in public ownership by the Northwest Florida Water Management District, the Nature Conservancy, and the Division of Forestry.

Anthropogenic Impacts

The Choctawhatchee River basin exhibits more water quality problem areas than other low population density, northwest Florida basins. Overall water quality ranking is good; however, several small tributaries exhibit fair to poor quality. Sampling of the upper Choctawhatchee River in the early seventies showed only fair water quality due to Alabama domestic and industrial discharges as well as agricultural runoff in Florida. A lack of recent data makes it difficult to determine water quality, but local water quality managers indicate that agricultural, logging and dirt road runoff is still a problem. Tenmile and Wrights Creeks, also in the upper basin, are subject to similar nonpoint pollution. In addition, the City of Noma WWTP, discharges to Wright's Creek, and has been experiencing periodic operational/maintenance problems.

Upper Holmes Creek and its tributaries also have water quality problems, primarily due to WWTP point sources and agricultural runoff. Four small municipalities (Graceville, Vernon, Chipley and Bonifay) have historically had problems with their wastewater treatment systems which have lead to the degradation of the receiving waters and, ultimately, Holmes Creek. The 1988 Nonpoint Source Assessment reports odor, oxygen depletion, algal growth and some fish kills in the upper Holmes Creek basin. All of the treatment plants have been under enforcement. Although they have made upgrades, problems still exist. Of particular concern are the Chipley and Bonifay plants, the latter of which has increased its discharge to Camp Branch Creek to accommodate a new federal prison. The City of Bonifay constructed a new facility with treatment requirements of

The City of Chipley remains under a Consent Order until corrective measures are completed. The City of Vernon remains a problem source. They were recently notified of a no discharge WLA and requested to apply for a TOP to eliminate the discharge to the tributary to Holmes Creek and to construct an upland disposal site. Currently they remain under a Final Order. The City of Graceville was issued a TOP in April, 1994. The TOP requires upgrading to AWT or elimination of the discharge to surface waters by January 1997. In addition to these WWT`Ps, Holmes Creek receives runoff from agricultural areas and hog farms that occasionally spill waste from their highly eutrophic impoundments. Water quality in lower Holmes Creek improves, partially, due to the input of several springs near Vernon. Finally, Reedy Branch, which empties into Holmes Creek, was only sampled in 1971, but showed poor water quality then, perhaps due to heavy agricultural runoff. Problems in the southwestern portion of the basin center around West Sandy Creek and Bruce Creek. The City of Defuniak Springs discharges 0.75 MGD domestic wastewater into West Sandy Creek. A bioassessment conducted in June, 1990 revealed almost exclusive dominance by blood-worm midges, Chironomus V below the outfall and this facility has had a history of sludge spills into the creek, thus a no discharge wasteload allocation was issued in September 1992. The City has found an upland site and a subsurface discharge investigation was scheduled for March, 1994. The Consent Order requires the elimination of their discharge to West Sandy Creek and disposal of the effluent to an upland site by March, 1996. Bruce Creek received effluent from a chicken processing plant (Showell Farms) which has also improved treatment. Showell Farms is now discharging their 1.25 MGD wastewater on an approved upland site. Finally, Bruce Creek receives sediment loads from the local county roads.

There is little STORET data on the main stem of the Choctawhatchee River below Interstate Highway 10, but there is little development and few pollution sources. However, there are some disturbing trends reported concerning the river, and there is a general perception that the biological resources are in poorer condition than expected. Certain fish populations have severely declined, notably striped bass. The lower reach of the river near the bay shows biological degradation with low numbers of species found.

The Northwest Florida Water Management District has conducted a study of the river, including water quality sampling. As a part of the study, pesticide and herbicide sampling found atrazine, a herbicide, in 17 out of 18 samples in 1987. Otherwise the report generally indicates "good" water quality index measures for the river.

Otter Creek (in Holmes County) had ammonia odors from livestock in the creek and algal blooms upstream and was channelized for cattle grazing downstream. Parrot and West Pittman Creeks had altered benthic community structures with many clean water species

missing and turbid waters with an accumulation of sediment from predominantly agricultural watersheds. Lighter Snag Creeles channel was filled with agricultural sediment leaving pools of stagnant water. Wrights. Creek above Noma had cattle in the stream with resulting turbidity and animal waste. Upper Camp Branch receives run-off from dairy farms with documented colifon-n bacteria violations. Gum Creek had historical fishkills from cattle using the stream and the same livestock management practices exist at this time. Flat Creek below Chipley is severely impacted by agriculture and at some locations cattle use the stream with resulting bare earth, erosion, and sedimentation eliminating native fish and wildlife.

Health advisories recommending limited consumption of largemouth bass due to mercury contamination have been issued for the Escambia River.

Ecological Characterization

Just north of the Florida-Alabama state line, the Conecuh River and Escambia Creek join to form the Escambia River. The Escambia River flows approximately 92 miles south from the Florida-Alabama state line to Escambia Bay. The drainage basin encompasses a total of 4,200 miles, only 10% of which is located in Florida. The average flow of the , Escambia is 6,500 cfs; however, the flow rate is highly variable. The Escambia River is an

74

alluvial river, draining mostly agricultural and forestry lands. The upper basin is mostly sandy, well-drained soils, while the lower basin has more swamps, sloughs and a relatively wide floodplain. The river is characterized by its -numerous cut-offs, oxbows and meanders. In-stream islands are common. At its mouth -the river breaks into -numerous channels -and bayous eventually emptying into Escambia Bay, -one of the major lobes in the Pensacola Bay basin. During low flow, a saltwater wedge penetrates -about 8 miles upstream.
Land use in the upper basin is primarily agriculture, while the lower river has more silviculture. Urbanization is occurring along the tributaries and at the river's mouth.

Anthropogenic Impacts

Water quality in this basin is generally good, but the Nonpoint Assessment found most of the tributaries to be threatened and a couple are moderately impaired. The Canoe Creek and Pine Barren:Creek systems suffer from agricultural and dirt road runoff. Sedimentation, high turbidity and pesticides are suspected to be causing declining fisheries. However, the Soil Conservation Service is designing a cropland watershed plan to alleviate agricultural runoff in the Canoe Creek drainage and much of the Escambia River.

Point sources in the upper basin include the Container Corporation (a paper company in Alabama at the state border), and the WWTPs of the cities of Century and Jay. Preliminary results of a basin assessment by DEP indicate elevated bacteria values downstream of Century. Bluff Springs Campground WWTP which discharged into a tributary to Canoe Creek will go toa septic tank with sand filter and subsurface drain field by the end of 1994. A point source assessment for the Town of Jay in August, 1992 showed severe biological impairment in Bray Mill Creek. Taxa richness and species diversity was dramatically reduced below the outfall which would indicate toxicity. Bioassay samples of the effluent and receiving stream showed 100% mortality of the test organisms within 10 minutes. Chlorine residual of the effluent was 1.7 mg/l and the creek was 1.5 mg/1, which was indicated as the cause of the mortality. The creek contains at least 88% effluent therefore a no discharge wasteload allocation was issued in September 1992. They are working on plans for construction of an upland site for elimination of their current discharge to Bray Mill Creek.

The old Century facility was abandoned and discharges to the old location ceased in 1991. The new Century facility discharges directly to Escambia River. In addition, there are gravel mining operations near Century. The Soil Conservation Service is conducting a feasibility study of restoring Big Escambia Creek from previous mining activities. Until recently, the pesticide Guthion was aerially sprayed on cotton fields in Santa Rosa County. Fish kills in private impoundments resulting from spray runoff prompted a hearing ruling' to tighten spraying restrictions and replace Guthion with Malathion.

60 of 115 2/10/2012 10:08 AMNear the mouth of the river, point source discharges include Monsanto Textiles Company, the University of West Florida WWT? and thermal effluent from a power plant. A no discharge WLA was issued to the University of West Florida WWTP in March 1993. These point sources are discussed in more detail in the Escambia Bay section of the Pensacola Bay Basin narrative summary. The lower river is also affected by nonpoint pollution from increasing urbanization as well as the point sources.

Sandy Hollow Creek disappeared after sedimentation filled its channel and adjacent wetland due to agricultural run-off and now the Soil Conservation Service is working to stop the erosion. Moore and Holly Creeks receive significant agriculture run-off impacting fish and wildlife. Significant runoff from the agricultural areas of Santa Rosa County has resulted in sedimentation filling stream channels not only eliminating fish and wildlife habitat but, also causing rising waters to periodically destroy many of the bridges at steam crossings. Citizens still complain about lack of fish and the disappearance of native mussels caused by pollution in the Escambia River from the Container Corporation just across the state line in Alabama.

Basic Fact

Drainage Area: S69 square miles Major Land Uses: forest, wetlands Population Density: low (Carrabelle) Major Pollution Sources: WWTP, septic tank seepage, marinas Best Water Quality Areas: New River, Juniper Creek, Crooked River Worst Water Quality Areas: Carrabelle River near WWTP Water Quality Trends: no trend data OFW Waterbodies: Alligator Harbor State Aquatic Preserve Apalachicola Bay State Aquatic Preserve SWIM Waterbodies: none Reference Reports: Florida Nonpoint Source Assessment, DEP (Tallahassee), 1999 Basin Water Quality Experts: Gray Bass, FGFWFC, 904/957-4172 Don Ray, DEP (Pensacola), 904/444-8300

In the News
Upgrades in treatment and discharge of the Carrabelle WWTP occurred in 1988. Tate's Hell Swamp (184,000 acres) was sold in 1991 by Proctor and Gamble to a Georgia land broker.

Ecological Characterization

The New River Basin is a small panhandle Florida coastal basin between the Apalachicola River and Ochlockonee River basins. The basin drains about 569 square miles of1ow wet forest in Liberty and Franklin Counties. Its headwaters are in the Apalachicola National Forest, and it flows through Tate's Hell Swamp. The swamp is a vast forested plain that was extensively ditched, drained, cleared and replanted in the mid-1960s. The river is very

82

darkly stained, one of the "blackest" of the blackwater'streams. Forestry and wetland areas are the predominant -land uses in the basin. After its confluence with Crooked River, the stream becomes wider, estuarine -in character andis calledthe Carrabelle River. Little of the land in the basin has been developed. Only 1% of the basin is urban area, principally the coastal community,of Carrabelle. Seafood processing is thearea!smajor economic activity.

Anthropogenic Impacts

Sampling of the New River hasbeen very Jimited; however, it drains, an Areanearly devoid of pollution sources except for a few logging operations and roads. The,portionof-the basin in St. George Sound also has good water quality -except 6or a small area near Carrabelle. The city previously discharged primary -treated wastewater directly into the Sound. A new plant with both improved treatment and discharge to a sprayfield began functioning in 1988. However, marinas and small shellfish processing areas in Carrabelle and Eastpoint continue to threaten water quality in their immediate vicinity. One of the larger processing facilities was ordered to discontinue their surface water discharge.

The streams in this basin have been severely modified by dredge and fill activities from past and present silvaculture practices. Planted pines have replaced native hardwoods along stream banks, topography flattened, stream channels filled from logging roads/clear cutting, and deep ditches are used to lower the basin's water table.

* Concern over the health of Lake Jackson led to a temporary building moratorium in the immediate watershed area in 1989. * Health advisories recommending limited consumption of largernouth bass due to mercury content have been issued for Lake Talquin, Lake lamonia, and the Ochlockonee River.

Ecological Characterization

The Ochlockonee River originates in the clay hillsof Georgia, entering Florida approximately 15 miles north of Tallahassee. The river flows 162 miles, first through rolling piedmont hills near the headwaters, then through sandy coastal,plains beforeentering the Gulf of Mexico at Panacea, Florida. An impoundment, Lake Talquin, lies

69 of 115 2/10/2012 10:08 AMdirectly west of Tallahassee covering 8,850 acres. The Ochlockonee River averages 1,600 cfs upstream of Lake Talquin, although flow in the river fluctuates widely with occasional periods of flooding and drought. The Florida drainage basin is 1,253 square miles (there are an additional 300 square miles in Georgia).

The upper river and the Little River tributary are more alluvial in nature than blackwater, although both have some color. Land use in the upper clay hills portion of the basin is mostly agriculture, and many of its headwater tributaries are impounded for farm ponds. To the east of the upper river, in Florida, are two shallow lakes that are undergoing rapid residential development. The southernmost, Lake Jackson, receives a substantial portion (roughly one-third) of Tallahassee's urban drainage. Lake Jackson also has the distinction of periodically (on average every twenty-five years) draining via sinkholes, leaving only a few deep pools. In the middle in pounded section, Lake Talquin has both agriculture and silviculture land use. The lower river flows mostly through forested coastal lowlands encompassing the Apalachicola National Forest. A remote blackwater creek, the Sopchoppy River, and the Ochlockonee River both flow into the western end of the Ochlockonee Bay, a small embayment along the Apalachee Bay coast.
Anthropogenic Impacts

There are several problem areas evident in this basin, mostly in the upper portions of the basin. First, Little River and its upstream tributary, Quincy Creek, have historically shown bacteria, nutrient and turbidity problems. Upstream point sources include strip mines (Englehaid, Floridan, and Oil Dry for Fuller's earth) and the City of Quincy WWTP (1. 5 MGD design capacity). The only background stream for monitoring fuller's earth mining is Attapulgus Creek northeast of Attapulgus Ga. as all the streams of this region in Florida are impacted by mining activities.

Bioassessment by Butts, 1990 found degraded conditions in Womack Mill Creek below the Havana WWTP discharge. Effluent water chemistry showed elevated BOD (21

99

mg/L), ammonia (I I mg/L), and coliform bacteria violations. Benthic macroinvertebrate fauna below the discharge was dominated by pollution tolerant forms including oligochaete worms (66% of fauna) and tolerant chironomid larvae (21% of fauna). An advanced wastewater treatment WQBEL was issued. An AWT WQBEL was re- established in April 1993. The City of Havana was issued a TOP in 1993 requiring an upgrade to AWT or an elimination of their surface water discharge by October, 1996.

Another problem area is the Ochlockonee River immediately below the Georgia-Florida state line. Water quality problems include high bacteria, nutrient and turbidity values and low macroinvertebrate diversity. A 1987 survey of the upper Ochlockonee basin conducted by the DEP Biology Section indicated that the primary source for the heavy turbidity and siltation is agricultural runoff in Georgia. Siltation is also apparently responsible for the depressed macroinvertebrate community and consequent decline in the fisheries reported by the Nonpoint Source Assessment. The Georgia Soil and Water Conservation Committee is applying for federal funds through the Georgia Environmental Protection Division to begin implementing farming Best Management Practices. Georgia point sources (primarily WWTPs and a pickle canning factory) appear to be responsible for the nutrient and bacteria problems in the upper reaches.

Lake Talquin has good water quality, 'with the exception of its junction with Little River where the stream adds nutrients and turbidity. There are some algae and aquatic weed problems, but the lake still serves as an excellent fishing and swimming area. It also acts to improve water quality downstream by allowing turbidity to settle out.

A tributary to the Ochlockonee, Telogia Creek, has severe nutrient and DO'problerns in the upper portions due to runoff from the Gretna WWTP overland flow /sprayfields. Court action has been taken against the City of Gretna to remove all discharges from Telogia Creek. The Court settlement is pending. Nutrient and weed problems extend several miles downstream.

Water quality in the Lower Ochlockonee River is good. Turbidity, sedimentation, bacteria, and stream 'habitat destruction was observed from county road maintenance in Caney and Pine Creeks along C-375 below Lake Talquin. Additionally, the Sopchoppy River has excellent water quality. However, Ochlockonee Bay is reported to have high nutrients and low macroinvertebrate diversity, perhaps due to nonpoint sources (construction, clear cutting and septic tank leachate) in the immediate vicinity of the bay.

Finally, concern about Lake Jackson in Tallahassee is growing. Although for the most part the water quality is still good, the lake and sediments, especially in Megginnis Arm, are threatened from residential, construction, and road/parking lot stormwater runoff. There is a stormwater treatment facility, but it is undersized and has had operating troubles. A major restoration effort, the dredging of contaminated sediments from Megginnis Arm, was recently completed. Due to local controversy and the fact that the

90

lake is a priority SWIM waterbody, more attention is being directed toward the expansion and maintenance of the facility and other lake management improvements.

The other major waterbody in' the basin, the Sopchoppy River, predominantly draming wetlands and forest land, shows excellent water quality. Its high color, low pH, and

Ecological Characterization

The Pensacola Bay Basin (located in northwest Florida) has a drainage area of 543 square miles. The basin consists of several connected waterbodies. To the west is Escambia Bay which receives flow from the Escambia River at 6,500 cfs. The Blackwater River (400 cfs) and Yellow River (1,500 cfs) empty into Blackwater Bay which widens to become East Bay. Escambia and East Bays are relatively low salinity estuaries. They merge to join the more saline Pensacola Bay waterbody which opens to the Gulf of Mexico between Perdido Key and Santa Rosa Island. Santa Rosa Sound is a lagoon between the mainland and Santa Rosa Island that receives very little freshwater input.

Most of the eastern portion of the basin consists of state forest lands and Eglin Air Force Base. The city of Milton lies at the head of Blackwater Bay. The Escambia River drains mostly silvicultural lands, but the Escambia Bay drainage contains considerable urbanization. The Pensacola Bay portion of the basin is almost entirely urbanized.

Anthropogenic Impacts

The main water quality problems in the area are upper Escambia Bay and the nearshore portions of Pensacola Bay. Additionally, Bayou Chico and Bayou Texar drain the Pensacola urban area and have pollution problems.

Water quality problems in Escambia Bay are mostly due to point sources. Reduced DO concentrations, fish kills and bacteria problems have been evident around the mouth of the Escambia River. The University of West Florida WWTP, Monsanto industrial discharge and Gulf Power thermal discharge enter the Escambia River upstream of the mouth. The University of West Florida's WNVTF was issued a TOP requiring actions to be taken to either upgrade th-- facility to AWT or eliminate their current discharge to surface waters. In addition, this portion of the bay received discharge from two chemical manufacturing companies (CYTEC, formerly American Cyanamid, and Air products). Both discharges have been found to be toxic in several bioassay tests. Monsanto also has a history of 

# Florida water quality assessment 1994 305 (b) main report http://www.gpo.gov/fdsys/pkg/CZIC-td224-f6-h36-1994-v-4/html/CZIC-...

81 of 115 2/10/2012 10:08 AMtoxicity. These companies discharge high levels of nitrogen and BOD. Problems in the upper bay were complicated by poor flushing due to natural circulation patterns and an old railroad bridge. A new railroad bridge has recently been constructed and the old one removed. Reports indicate significantly better circulation. Located on the eastern side of Escambia Bay is Mulatto Bayou which receives stormwater runoff from Avalon Beach.

106

Indian Bayou, in the southeastern portion of Escambia Bay, still supports a seagrass bed community.

Water quality improves in Pensacola Bay, mostly due to better flushing and the greater influence of Gulf waters. However, both nonpoint and point sources affect the bayous in Pensacola. Bayou Chico has very poor water quality. The bayou has bacteria, fish kill and nutrient problems. In addition to stormwater, it receives shipyard runoff, historic discharge from Reichold Chemicals, and the Warrington WWTP discharge. Historically, it was also degraded by chemical, lumberyard and creosote industries. Sediments are polluted with metals and support reduced macroinvertebrate life. A study of the sediments performed by the University of Florida found that various polycyclic aromatic hydrocarbons (PAH) and phenolic compounds were migrating from the American Creosote site to Pensacola Bay at the mouth of Bayou Chico (Delfino et al., 1991). The investigators also found I I OPP's and 3 PAHs and p-chloro-m-cresol in the waters of Bayou Chico. The water concentration of tetrachloroethylene (11.5 mg/1) at one station exceeded both EPA Human Health Criteria and the FDEP Surface Water Quality criteria for Class III waters. Additionally, at two stations phenanthreone and pyrene also exceeded the EPA Human Health Criteria. The two creeks which feed this bayou (Jackson Creek and Jones Creek) also exhibit water quality problems from urban runoff. Several actions have been and are being taken to alleviate problems in Bayou Chico. Improved stormwater treatment from the shipyards, Reichold Chemicals, Corry Field (a Navy installation) and a shopping complex have been negotiated. Additionally, a sedimentation basin (funded mostly by DEP) is being constructed in one of the three arms of the bayou to capture sand and organic sediment from stormwater. The Warrington plant has upgraded its treatment and since 1990, discharges to the Main Street W)ArTP rather than Pensacola Bay. DEP has been conducting a survey of sediments in port areas throughout the State. This study found that sediments in the Pensacola Bay port area east of Bayou Chico were the only ones in the State to contain phenols.

Bayou Texar, although not as degraded as Bayou Chico, has had increasing fish kill problems in recent years. It receives discharge from 68 storm sewers and discharge from Carpenters Creek containing heavy suspended solids loads. Recently, the City has proposed a demonstration project (funded by DEP) to modify four of these sewers to allow partial treatment of the stormwater before entering the bayou. In addition, a study by the University of West Florida will assess the problems of the bayou and make recommendations. As part of the Pensacola Bay SWINI plan, these two bayou drainages, as well as other drainages, will be monitored to determine their pollutant loading to the bay. The summer and fall of 1991 were particularly devastating for marine life. Large fish kills occurred in both Bayous Chico and Texar. As much as 10-12 tons of fish were removed. Crabs dying in traps were found in Santa Rosa Sound. High nutrient runoff

107

from Tiger Point Golf Course and low dissolved oxygen levels probably contributed to the die-off of crabs.

Pensacola Bay proper also receives discharge from Pensacola's Main Street wastewater treatment plant. Two years of water chemistry samples were collected by the facility in the bay around the discharge point and at several background sites. They indicated that the bay was assimilating the current discharge but that loadings should not be increased. DEP biological sampling indicates low diversity and heavy organic sedimentation a-round the discharge. Furthermore, the plant has been found toxic in several bioass4ys.

The USEPA has research projects in Pensacola Bay including EMAP and estuarine assessments of Bayou Chico, Bayou Texar, and Bayou Grande. Sediment toxicity, chemistry and benthic macroinvertebrates are included as research parameters. Preliminary findings has shown sediment toxicity in upper Bayou Texar below the 12th Avenue Bridge. No scientifically defensible cause and effect have been established for-this observation at this time. Recent 5th year surveys for Navarre WWTP, NAS WWTP, and Main Street WWTP have not shown biological impact due to these sources, however AGP results indicate that nutrient loading to Pensacola Bay should not be increased.

Santa Rosa Sound has good water quality. It is threatened by development of the island, ditching and stormwater. Only two WWTPs currently discharge to Santa Rosa Sound, Navarre Beach and Pensacola Beach. Both facilities provide tertiary treatment prior to discharge. Finally, the City of Navarre has proposed cutting a pass (and marina) through the island.

Dissolved oxygen violations were recorded in upper Escambia Bay below industrial outfalls during April, 1994. Citizen continue to complain about dirty foam originating near these outfalls. Additional public complaints were received that the CYTEC (formerly American Cyanamid) outfall pipe had broken again.

82 of 115 2/10/2012 10:08 AMSerious fishkilis occurred in East Bay during September 1993. This area's history is similar to Bayou Texar where increased development led to increased nutrient loading which during neap tides with little wind mixing during cloudy late summer/early fall caused die off of algal blooms and fishkills. The East Bay area is developing with many waterfront home owners and the resulting nutrient laden nonpoint source runoff is beginning to contribute to the fishkills. A bridge permitted in June, 1994 to cross East Bay can be expected to exacerbate population growth in the watershed.

108

Mulatto Bayou has experienced turbidity, sedimentation, and habitat destruction from construction of a golf course in its headwaters. Enforcement action resulted in sediment dredging from the Bayou. Local homeowners still complain that fish and wildlife are now scarce in the bayou and blame runoff from the Moors golf course development.

Fishkills around Tiger Point golf course/WWTP in Santa Rosa Sound for summer 1993 were reported after the fact by citizens and the Gulf Islands National Seashore park supervisor.

Big Lagoon's water quality data has been added to the Perdido Bay basin section of this 305(b) report. It is an OFW with Big Lagoon State Park and Gulf Islands National Seashore Park and has the only nursery area of turtle (Ihalassia) seagrass beds in Escambia Co. This area is being intensely developed with condominiums, subdivision, and marinas.

Ecological Characterization

Perdido Say is a relatively small Florida estuary (50 square miles) with an immediate drainage area of approximately 300 square miles. The center line of the bay forms the state boundary line between Alabama and Florida, with each state sharing approximately half of the basin drainage area. The Perdido River is the major- freshwater -inflow to the bay with an average annual flow of 700 cfs. Florida land use in the immediate drainage basin is primarily forest though a portion is rapidly becoming urbanized (western -edge of Pensacola). The Alabama side has agriculture as well as silviculture.

Because of its small, "off-center" inlet from the Gulf, the bay is subject to rapidwater quality changes depending on rainfall, wind and tidal effects. After rainy periods and with north winds, the bay experiences extreme outflowing currents, rapid flushing and low, salinities. During low rainfall, low wind periods, the bay is very poorly flushed, thus concentrating pollutant inputs.

Anthropogenic Impacts

The most concentrated and voluminous pollution source in the basin is the Champion Paper Company (formerly the St. Regis Paper Company) which discharges 28 MGD of treated pulp mill effluent into Elevenmile Creek making up most of its flow at its headwaters. The historical record shows that the creek has had major water quality problems since the early 1970s. After the installation of a treatment facility at St. Regis Paper Company, water quality parameters showed improvement in the mid-1970s; however, in the mid-1980s Champion changed production methods to include a bleaching process. This change required a new permit. In the summer of 1987, the company applied for an operating permit and for variances in zinc, iron, lead, specific conductivity and transparency. The permit was contested by a local environmental group. After lengthy administrative hearings, and under a complicated Consent Order requiring studies of both treatment processes and water quality impacts, a five year temporary operation permit with the variances was issued in December 1989.

The discharge negatively affects many in-stream water quality parameters, particularly g biological integrity, color, DO, BOD, nutrients, turbidity and solids. Of the 81 STORET samples from the creek taken in the last ten (10) years, the median value for DO was 3.4 mg/l which is below the state criterion of 5 mg/l for Class III waters. Dissolved oxygen violations were recorded for Perdido Bay and ElevenMile Creek during the spring of 1994. The Department continues to receive many water quality complaints for Perdido Bay. Complaints from ElevenMle Creek below the papermill now include mats of duckweed flowing downstream which appear to be from changes in the mill wastewater treatment process. The poor water quality throughout the creek is reflected in low density, diversity and species richness values for benthic fauna. The company is investigating the possibility of going to land application rather than direct discharge. This

116

should improve water quality, but would have a pronounced effect on flow in the creek. In the meantime, Champion has invested in numerous studies and treatment methods. One report indicated a 70% reduction in effluent color and further color removal studies are being conducted. Treatments to reduce color are likely to have positive effects on BOD and other parameters.
Other dischargers to Elevenmile Creek included the Silver Lake WVVTP and the Cantonment WWTP. Silver Lake WWTF is no longer in operation. Flows were diverted to the Escambia County Utility Authority facility in January, 1994. The Cantonment WWTF has been notified of a no discharge WLA. A TOP is in effect requiring diversion of flows to the Avondale WWTF and the elimination of their discharge to ElevenMle Creek by February 1998. The Cantonment WV*ITP discharges just above the Champion discharge.

In the last several years, a number of studies have been initiated by DEP (CZM), EPA, Alabama Department of Environmental Management, Fish and Wildlife Service, and Champion to investigate the effects of Elevenmile Creek and other tributaries on the bay itself. This is a difficult question to answer because of the overwhelming influence of the Perdido River (relative to the unusual flushing characteristics of the bay (sometimes very rapid, sometimes slow), and the extreme variability of the bay itself The DEP (CZM) study indicates that Eleverimile Creek currently contributes approximately 30% of the nutrients and only 10% of the freshwater input to the Bay, and that the excess carbon contributed by Elevenmile Creek may exacerbate seasonal low DOs in the bay. Overall, however, it is still unclear from the DEP (CZM) and Champion studies if the creek has significant long term deleterious effects in the bay. Additionally, a sampling of 48 fish (several species) from the bay were found to have normal liver histopathology by EPA (Gulf Breeze). Work on fish fillet dioxin concentrations by the EPA resulted in advisories being issued urging no consumption of fish from Elevenmile Creek. Fish fillets sampled exceeded EPA recommended maximum levels of 7 parts-per-trillion of dioxin. Another

88 of 115 2/10/2012 10:08 AMstudy of the bay's ecology has been performed by EPA (Athens). The Perdido Bay Cooperative Management Study will make a comprehensive assessment of all the studies and identify specific management strategies for improvements to the bay. This study is nearing completion.

Upper Perdido Bay also receives drainage from Eightmile Creek and Bayou Marcus which receive runoff from urbanized areas and have elevated water quality index values. In addition, the Avondale WWTP discharges to Bayou Marcus. The Avondale WWTP was upgraded to AWT in 1989 which improved the downstream water quality of Bayou Marcus. Avondale WWTF was issued a construction permit in June 1994 to expand the facility from 2.0 MGD to 7.1 MGD and to dispose of it's effluent to a wetland adjacent to Bayou Marcus AWT. Construction is to be completed prior to March 1997. Stormwater continues to be a pollution source to the bayou and the bay from a variety of nonpoint

117

sources. The Florida side contributes mostly urban and construction.stormwater, whereas the Alabama side has more agricultural runoff.

Bayou Garcon, in the southern portion of the bay, exhibits transparencyand DO prDblems. In addition, there have been local reports of increased siltation at the, rnouthof the bayou which was attributed to new development in the watershed area. Within thelast few years, there has been an increase -in development in the.swampy areas west of Pensacola. During rainy seasons, runoff from these developments can;affect much of the eastern portions of the bay. The runoff problem is a major concern because the bay studies indicate that the lower bay is also susceptible to sediment and water pollution.

Ecological Characterization

124

The Perdido River forms the boundary between Florida. and Alabama. The basin' �
, drainage area'is-913 square Miles, of which only 25% is located in Florida. The -river i's blackwater in nature and meanders through mostly sand and gravel substrate, The@river discharges at about 700 cfs into Perdido Bay and is estuarine an&tidal in its--lowest reacir. The basin is mostly forested, and silviculture. is the pnimary land use in Florida; however, the upper basin contains significant. agricultural- lands.. There - islittle urban. area within the basin.

Anthropogenic Impacts

Water quality in'the uppet'basin is generally good. All stream reaches meet-their- designated use. One historical problem area in the,basin is Jacks Branch. In the.early 1980.s, there was some hazardous waste contamitfation: from Dubose. Oil, Company 'to., JacksBranch. Since that time the State and EPA have contained, this pollution source -and are involved in the cleanup process.

The lower river reaches are allected by water fi-om Perdido Bay.. The lower river. i& considered fair to poor by district personnel, exhibiting very low bottom DO levels,*aitd, concomitant low benthic diversity values.

Specific problems that have occurred are as follows. The Perdido Landfill had water quality violations of turbidity, fecal and total coliforms, and pH, in tributaries emptying into the Perdido River. In addition, 28 acres ofjurisdictional wetlands were filled without a permit. Escambia County signed a Consent Order and agreed to pay FDEP expenses, fund an environmental education project, release 183 acres for a conservation easement on property between Perdido Landfill and the Perdido, restore disturbed wetlands, and submit a Surface Water Assessment Plan f67r the facility. A criminal investigation of the Perdido landfill was Conducted during 1993/4 by EPA. State monitoring found a contaminated stream flowing off the property with very low diversity and an altered community structure dominated by bloodworms. A background tributary just upstream was clear, with a diverse benthic community with fish, stoneflies, and mayflies etc.

Boggy Creek has severe erosion problems from historical silviculture activities as reported by the Soil Conservation Service. The water body is a candidate site for FDEP's Pollution Recovery Trust Fund.

# Florida water quality assessment 1994 305 (b) main report http://www.gpo.gov/fdsys/pkg/CZIC-td224-f6-h36-1994-v-4/html/CZIC-...

97 of 115 2/10/2012 10:08 AM* The dredging operation at Military Point Lagoon has been completed. The lagoon, which serves Bay County, the Four City Sewer System, Tyndall Air Force Base, Stone Container Corporation and Panama City was cleared of a large buildup of sludge. Biochemical oxygen demand has been -reduced by 50 percent. * Health advisories recommending limited consumption of largemouth bass due to mercury content have been issued for Deer Point Lake and Econfina Creek.

131

� A notice of violation was given to Bay County for 66 sites because of stonnwater runoff caused erosion and sedimentation into waters of th-- State. � A die-back of salt marsh cordgrass has been occurring along the inner perimeter of the St. Andrews Bay.

Stone Container pulpmill will be closed most of the surnmer (1994) due to an industrial accident.

Ecolop-ical Characterization

St. Andrews Bay Basin encompasses a large bi-lobed em, bayment on the panhandle of Florida. To the west of the inlet, West Bay and North Bay form one lobe. On the southeast is St. Andrews Bay proper, and East Bay forms the other lobe. Panama City fies between the lobes. The basin also includes the long stretch of coast enclosing St. Andrews Sound, and the large, open St. Joseph's Bay. The major freshwater inflow into the bay complex is the Econfina River, entering at North Bay. The northernmost bayou where this spring-fed river enters the bay is impounded to form the freshwater lake, Deer Point Lake, which is the drinking water source for Panama City. Other freshwater drainages into the bay are small, mostly blackwater creeks draining forest and swamp land. St. Josephs Bay, in the southern part of the basin, is distinctly different from the dark brackish waters of West, North and East Bays. It is essentially composed of the clear, saline waters of the Gulf of Mexico, and is separated from the Gulf by a thin dune line. There are no major freshwater inflows; however, the brackish Gulf County Canal connects the bay to the Intracoastal Waterway.

The entire basin drains a total area of about 1,350 square miles. The watershed is primarily forested with an urbanized area concentrated adjacent to St. Andrews Bay. The major urban centers are Panama City, Lynn Haven and a narrow strip of development along the gulf Except for these urban areas, the primary land use is silviculture.

Anthropogenic Impacts

The St. Andrews Bay system generally exhibits good water quality. The major river inflow, Econfina Creek, is nearly pristine, and most of the urbanized area is concentrated where the bay is better flushed by the Gulf However, the Bay is threatened, not only by the growth-induced nonpoint source pollution, but also by several important domestic and industrial point sources.

132

There are several areas of concern in the basin. Deer Point Lake is the drinking water source for Panama City. Although its major inflow is from Econfina Creek, its other tributaries have some pollution impacts. Bayou George Creek has the Majette Landfill located in its watershed. In a 1987 study, Pond C effluent to the creek had significant amounts of ammonia and unionized ammonia. The creek below the landfill had elevated nutrients and specific conductance, and the macroinvertebrate community was depressed. Perhaps most threatening to the lake itself is the impact from recreation activities and shoreline development. Boating docks and facilities, construction activities, and residential development runoff add fertilizer, sediment and oils and grease to the watershed. The lake has severe weed problems which were treated by both the State and private citizens with herbicides in the seventies. Chemical treatment has been replaced by biological controls (grass carp). Sampling in 1989 indicated elevated values for some metals in the sediments near the dam and depauperate benthic fauna and low diversities in the mid- to lower lake. Water quality sampling indicates low DO values and some bacteria problems. Deer Point Lake is a priority SVM4 waterbody and plans were developed for its conservation and restoration including a careful study of the nonpoint pollution sources in the watershed.

Nonpoint source pollution also affects several of the urban creeks and bayous. In addition, Beatty Bayou below the impoundment was affected by the Lynn Haven WWTP sprayfields. The plant diverted it's flows to the Bay County WWTP in April, 1994. Watson Bayou, in Panama City, also suffers from historical WWTP discharge and urban runoff. A major fish kill in the summer/fall of 1991 was linked to leaking sewage lines and a sewage discharge from the Millville WWTP. The Nonpoint Source Assessment

98 of 115 2/10/2012 10:08 AMindicates some metals contamination of that waterbody. A study performed by NOAA!s National Status and Trends Program found high concentrations of lead, mercury, DDT, chlordane, PCB's, and polycyclic aromatic hydrocarbons in sediments from Watson Bayou. West Bay in the vicinity of the Panama City Beach WWTP, is also showing water quality problems with decreased DO values. Panama City Beach's recent application for an operating permit renewal was denied based on their current discharge to Class II waters. This denial is currently in the hearing mode. It is anticipated that the matter will be resolved through a temporary operating permit requiring appropriate actions to be taken to eliminate any further discharges to their present location. Finally, the St. Andrews WWTP which handles wastewater from Panama City appears to be affecting the sediments and biological richness in the vicinity of its outfall in St. Andrews Bay. St. Andrews WWTP will be required to upgrade to AWT when their current permit expires in 1997.

The most significant point source problems in the basin are treatment plants that receive more industrial wastes than domestic. The Bay County Regional WWTP treats industrial

133

wastewater from Stone Container (paper/pulp mill) and Arizona Chemicals Company (a resin processor) as well as domestic - wastewater'fr6m several small- communities. The-Bay County facility and the industries have jointly signed a Consent Order requiring better- treatment and outlining the financial penalties for non-compliaince. St. Andrews, Bay, in- the vicinity of the outfall at Military Point, indicates biological degradation with poor diversity and productivity. The, sediments in the vicinity of the- outfall have: high BOD. and- are rich in organics.

The City of Port St. Joe WWTP (in Gulf County) treats wastewater from St. Joe Forest Products (paper/pulp mill). Premier Services Corporation (formerly known as Basic Magnesia, Inc.) treats wastes from it's magnesium operation. The WWTPI plant discharges enter the Gulf County Canal near the St. Josephs Bay where it becomes diluted, with good quality bay water. However, in the vicinity of the canal, sediments are mucky instead of sandy and seagrass coverage is decreased due to the poorer transparency of the- waters. Both Bay Count and City of Port St. Joe WWTP facilities discharge at- about 3-9 MGD (of which 80-90% is from the paper companies). Both are publicly owned treatment plants that mutually benefit the paper companies and the counties (by virtue of, having the industrial development). Both of the receiving bays show biological degradation and shifts in sediment composition. The WWTP's have applied for a TOP (temporary operating permit) which will require them to address current discharge problems resulting from high pH and TSS.

Lake Powell is ecologically interesting in that it has characteristics of both freshwater and saltwater lakes. It is also in relatively pristine condition; however, it is currently undergoing rapid development. The utmost care should be taken to prevent stormwater pollution in this sensitive area. It was recently designated as Outstanding Florida Waters.

Other pollution sources in this basin include many small package plants and septic tanks which discharge poorly treated waste into ditches emptying into the St. Andrews Bay, significant amounts of highway and construction site runoff, and runoff from logging operations.

Venture Out WWTP (currently discharging directly to St. Andrews Bay) will connect to Panama City Beach by November, 1994. Pride Resorts WWTP (currently discharging to Alligator Bayou) was issued a TOP in January 1994 requiring it to tie-in to the Panama City Beach WWTP or upgrade to AWT by October, 1994.

Ecological Characterization

The St. Marks River basin drains approximately 1, 180 square miles and extends from south Georgia to the Gulf of Mexico. It includes approximately one-half of the drainage from Tallahassee. The St. Marks begins as a tiny blackwater stream meandering through a series of sloughs and ponds. Lake Lafayette, on the outskirts of Tallahassee, also flows via a slough to the St. Marks when rainfall is great. Near the Leon-Wakulla County line, the river widens and clarity improves with water input from several springs, particularly Horn Spring. The river then plunges underground at Natural Bridge and emerges a short distance downstream at St. Marks Spring. Here, the stream is larger and more characteristic of a spring run, although during heavy rains it does become tannic. The

143

flow here averages about 700 cfs. Its sister river, the Wakulla, with-a flow of about 400 efs, emerges from Wakulla Springs about 10 miles to the west. The streams join- near the City of St. ?Aarks about 3 miles upstream from the Gulf of Mexic(Y.

Both river corridors are heavily wooded with cypress and other native vegetation; however, there are increasing numbers of home sites encroaching on both rivers. Both- rivers are used heavily for canoeing, fishing and swimming. Land use in-the basin is, largely for silviculture. The lower basin is teeming with wildlife in pine woods. and fresh and saltwater marshes. Much of this area is protected by the St. Marks National Wildlife; Refuge. Both rivers are designated as Outstanding Florida Waters.

Anthropogenic Impacts

Water quality is excellent in much of this basin. There are two areas in thebasin which have water quality problems. Munson Slough drains portions of the Tallahassee urban area and historically received treated wastewater from small package plants and runoff. from the city WWTP sprayfield. The stream system enters-Lake Munson and.then disappears into a sinkhole several miles downstream of the lake. The lake and stream system exhibit poor water quality with algal blooms, high nutrients, bacteria and transparency problems. Effluent from the major WVv1TP in Tallahassee has been diverted from Munson Slough to a land spreading operation. The lake still has problems relating -to

105 of 115 2/10/2012 10:08 AMurban runoff from Tallahassee.

A Lake Munson study was conducted in the mid- I 980s by the Department to determine the status of water and sediment quality as a first step toward a proposed restoration project. The study indicated that since the diversion of treated wastewater from Munson- Slough the algal growth potential has decreased tenfold and the biological. community has relatively good diversity. It was also determined that the low nutrient, highly tannic swamp waters draining into the lake have had a beneficial effect on the lake's, recovery. However, with the proximity of the lake and slough to ground water, there is a fear that the nearby chain of sinkholes will become polluted.

The other problem is in the St. Marks River downstream of Rattlesnake Branch (the-lower 3-4 river miles). This section of the river received effluent from Seminole Refining Corporation (which was found in 1985 to be acutely toxic to bioassay organisms) and Purdom Power Plant. The former company is under a Consent Order from DEP and is no longer operating. Seminole is in the process of remediating the site. To pay for the remediation, the property was sold to St. Marks Refining. St. Marks Refining was issued a temporary operating permit until 1996, but they are currently not refining oil at the site. In addition, there are docking and pumping stations for oil barges, and a few small marinas

144

for fishing and recreational boats. There have been several major and minor oil spills in the past, and sediments in the area are coated with oil. There is a small 50,000 GPD sewage treatment which discharges into the lower St. Marks River. Plant inspection in October, 1993 found no problems with toxicity, metals, W-BNA or pesticides, however algal growth potential (AGP) exceeded the EPA established threshold. Nutrient input into the St. Marks Basin is a cause for concern.

The Wakulla River is fed by one of Florida!s highest discharge springs and has excellent water quality. The upper portion of the river was recently bought by the State and made into a state park; however, the lower portion of the river is threatened by continued waterfront development with insufficient buffer areas along the river's edge. Near its confluence with the St. Marks, the Wakulla receives increased nutrient loading from Boggy Branch (Olin Corp. discharge). Olin is studying the problem.

Recently, problems have been noted in the Lake Lafayette drainage of Tallahassee's east side. These problems are being investigated,

* Health advisories recommending limited consumption of largemouth bass due to mercury content have been issued for the Yellow River. * A sewage spill into Trammel Creek from the Crestview WWTP resulted in large fish kill during November 1990. Approximately 13,000 sport fish died. Since 1988, Crestview WWTP has been cited for 2693 violations of federal rules regarding discharge of untreated or inadequately treated sewage EPA has proposed a $115,000 fine.

Ecological Characterization

The Yellow River Basin originates in Covington County, Alabamaand flows southward for approximately 92 miles before emptying into Blackwater Bayin Florida. The Yellow River Basin drains roughly 860 square miles of northwestern Florida. The largest tributary, the Shoal River, joins the Yellow River near Crestview, Florida, discharging an average of 1, 100 cfs. The rate of flow for the Yellow River (40 miles above the mouth) averages 1,500 cfs. The Yellow River is so named because its tannic waters appear yellowish against the white sandy river bed. The Yellow River's drainage basin is ,the highest in Florida and contains large sandy deposits' thought to be part of a barrier islands system when sea levels were higher. The river runs swiftly and creates high banks and large sand bars. The Shoal River is similar in character and drainage. After its confluence with the Shoal, the Yellow River becomes deeper and slower as it flows through the low swamp and marsh lands to the bay. Land use in the Yellow River Basin is primarily forest and agriculture. Crestview and Nfilligan are the largest towns in this basin. Much of the southern basin is a large Air Force base. It contains several landing fields and numerous roads.

Anthropogenic Impacts

The Yellow River has excellent water quality. The Shoal River has been declared an Outstanding Florida Water. All stream reaches in the basin which have been sampled exhibit good overall quality except for Trammel Creek. Upper reaches of the Yellow River have some impact from Alabama agricultural runoff, Florida hog lots and other agricultural activities.

Trammel Creek received treated wastewater from the City of Crestview WWTP (1.5 MGD design capacity) until April 1994. The creek exhibits nutrient and turbidity problems. The Crestview plant has had a history of treatment problems. A sewage spill in Trammel Creek in November, 1990 resulted in the death of approximately 13,000 sport fish. The City of Crestview constructed a new WVV7P and now disposes all of it's effluent to an upland site. The old discharge into Trammel Creek was discontinued inApril, 1994. Trammel Creek joins the Yellow River approximately 3 112miles west of the town of Crestview. The Yellow River was posted for non-contact by the Okaloosa County Health Department several times in the past two years after system failures at the Crestview WWTP. Runoff from the City of Crestview goes both to the Trammel Creek-Yellow River drainage and to the lower Shoal River drainage.

In addition, some areas in the basin near agricultural areas are threatened by nutrient, silt and BOD loadings from runoff. Particularly noted.are Pond Creek and the Shoal River near Crestview.

Horsehead Creek, east of Laurel Hill, was severely altered due to non-vegetated eroded banks, sediment filled channel, and livestock waste disposal.

Juniper Creek below Laurel Hill was in need of habitat restoration activities because of historical clearing and moving of the stream channel resulting in the lack of fish and wildlife propagation.

Hurricane Creek in the State Forest had a low diversity and an unbalanced aquatic community below the impoundment of Hurricane Lake.

Juniper Creek draining Crestview into Shoal River continues to be under enforcement due to severe erosion from unpaved Raspberry Road and clay/sand borrow pits.
