Water Quality Assessment Report: Springs Coast 7

Executive Summary

Springs Coast

The Water Quality Assessment Report for the Springs Coast Basin is 

part of the implementation of the Florida Department of Environmental 

Protection’s (Department’s) watershed management approach for restoring and protecting water resources and addressing Total Maximum Daily 

Load (TMDL) Program requirements. A TMDL represents the maximum amount of a given pollutant that a waterbody can assimilate and still 

meet the waterbody’s designated uses. A waterbody that does not meet its 

designated uses is defi ned as impaired. The watershed approach, which is 

implemented using a cyclical management process, provides a framework 

for implementing the requirements of the 1972 federal Clean Water Act 

and the 1999 Florida Watershed Restoration Act (Chapter 99-223, Laws of 

Florida).

A Status Report, published during Phase 1 of the watershed management cycle, provided a Planning List, or preliminary identifi cation, 

of potentially impaired waterbodies in the Springs Coast Basin. This 

Assessment Report presents the results of additional data gathered during 

Phase 2 of the cycle. The report contains a Verifi ed List of impaired waters 

(Table 5.3 in Chapter 5) that has been adopted by Secretarial Order and 

approved by the U.S. Environmental Protection Agency (EPA). TMDLs 

must be developed and implemented for these waters, unless the impairment is documented to be a naturally occurring condition that cannot 

be abated by a TMDL, or unless a management plan already in place is 

expected to correct the problem. The Verifi ed List also constitutes the 

Group 5 basin-specifi c 303(d) list of impaired waters, so called because 

it is required under Section 303(d) of the Clean Water Act. In addition, 

the report provides the results of a preliminary assessment of ground water 

quality and ground water to surface water interactions in the basin. It also 

discusses priorities for further evaluation, resource priorities, and proposed 

actions. (See Noteworthy in Chapter 1 for a description of the contents of 

this report, by chapter.)

In the Springs Coast Basin, state, federal, regional, and local agencies 

and organizations are making progress toward identifying problems and 

improving water quality. Through its watershed management activities, 

the Department works with these entities to support programs that are 

improving water quality and restoring and protecting ecological resources. 

The Department’s TMDL Program objectives will be carried out in the 

basin through close coordination with key stakeholders and initiatives 

such as the Southwest Florida Water Management District (SWFWMD); 

 SWFWMD’s Crystal River/Kings Bay Surface Water Improvement and 

Management Program; Pasco, Hernando, Citrus, and Pinellas Counties; 

and the municipalities of Port Richey, New Port Richey, Weeki Wachee, 

Brooksville, Crystal River, Tarpon Springs, Palm Harbor, Dunedin, 

 Clearwater, Largo, and Gulfport.

Water Quality Assessment Report: Springs Coast 9
Not only do stakeholders in the basin share responsibilities in achieving water quality improvement objectives, they also play a crucial role in 

providing the Department with important monitoring data and information on management activities. Signifi cant data providers in the basin 

include Pinellas County, the SWFWMD, the U.S. Geological Survey, and 

the Department.

During the next few years, considerable data analysis will be done to 

establish TMDLs for impaired waters in the Springs Coast Basin, establish 

the initial allocations of pollutant load reductions needed to meet those 

TMDLs, and produce a Basin Management Action Plan to reduce the 

amount of pollutants that cause impairments. These activities depend 

heavily on the active participation of the water management district, local 

governments, businesses, and other stakeholders. The Department will 

work with these organizations and individuals to undertake or continue 

reductions in the discharge of pollutants and achieve the established 

TMDLs for impaired waterbodies.

Summary of Surface Water Findings

The Department’s assessment shows that 57 waterbodies or waterbody 

segments in the Springs Coast Basin are impaired, and 31 of these require 

the development of TMDLs. The following summarizes, by planning unit, 

impairments by waterbody types and the primary pollutants. Planning 

units are smaller areas in the basin that provide a more detailed geographic 

basis for identifying and assessing water quality improvement activities.

Crystal River/Kings Bay Planning Unit

Of the 12 waterbody segments in the Crystal River/Kings Bay Planning Unit, 7 segments have suffi cient data for assessment. Of these, 3 are 

verifi ed impaired for at least 1 parameter assessed, none remain on the 

Planning List, and 4 meet standards.

The three verifi ed impaired segments in the planning unit, and the 

parameters of impairment, are as follows:

Hunters Bay Spring Dissolved oxygen (DO)

Tarpon Springs DO

Fort Island Gulf Beach Bacteria

Homosassa River Planning Unit

Of the eight waterbody segments in the Homosassa River Planning 

Unit, four segments have suffi cient data for assessment. Of these, one is 

verifi ed impaired for at least one parameter assessed, one remains on the 

Planning List, and two meet standards.

The verifi ed impaired segment in the planning unit, and the parameter 

of impairment, is as follows:

As part of the 303(d) assessment of the Springs Coast Basin, the 

Department received documentation from Pinellas County designed to 

provide reasonable assurance that proposed pollution control mechanisms 

would effectively address the nutrient-related impairment of Lake Seminole. While the fi nal agency action on this submittal will not occur until 

the adoption of the Verifi ed List of impaired waters for the Group 5 basins, 

the Department has concluded that the Lake Seminole Reasonable Assurance Plan provides reasonable assurance that the lake will be restored. 

As such, the Department will approve the reasonable assurance proposal 

as part of the list adoption and will place Lake Seminole in assessment 

 Category 4b (no TMDL required).

Total Maximum Daily Load Priority Areas

There are four high-priority areas for TMDL development in the 

Springs Coast Basin. Rule 62-303.500, Florida Administrative Code, 

defi nes high-priority waters as waterbody segments where the impairment poses a threat to potable water supplies or human health; waterbody 

12 Water Quality Assessment Report: Springs Coast
 segments where the impairment is due to a pollutant regulated by the Clean 

Water Act and the pollutant has contributed to the decline or extirpation of a federally listed threatened or endangered species, as indicated in 

the Federal Register listing the species; or waterbody segments verifi ed as 

impaired that are included on the EPA’s 1998 303(d) list as high priority.

The waterbody segments identifi ed as high-priority areas for TMDL 

development are as follows: Klosterman Bayou Run Tidal (waterbody 

identifi cation number [WBID] 1508) for DO, fecal coliforms, and nutrients (chlorophyll a), on 303(d) list; Stevenson Creek Tidal (WBID 1567) 

for DO and nutrients (chlorophyll a); St. Joe Creek (WBID 1668A) for 

DO and nutrients (historical chlorophyll), on 303(d) list; and Pinellas Park 

Ditch No. 5 (WBID 1668B) for DO and nutrients (chlorophyll a), on 

303(d) list. All of the remaining parameters causing impairment for the 

WBIDs placed on the Verifi ed List have been assigned medium priority for 

TMDL development. 

Summary of Ground Water and Springs 

Assessment Findings

This section summarizes the results of an assessment of the availability and quality of potable ground water supplies, the impact of ground 

water on surface water resources, and resource priorities in the Springs 

Coast Basin. Due to the signifi cant interaction between ground water and 

surface water via springs in most planning units in the basin, ground water 

is likely to infl uence surface water quality. The assessment uses planning 

units consistent with the surface water assessment and water quality data 

from a combination of databases maintained by the Department and the 

SWFWMD springs monitoring program.

Basinwide Observations of Elevated Parameter Concentrations

Elevated nitrate levels in the basin are well documented by SWFWMD 

work. These studies have shown that, overall, elevated nitrate levels 

are present in springs and are attributed to pollutant sources in their 

springsheds, primarily inorganic sources such as fertilizers. 

Ammonia (dissolved, measured as N) values from Floridan aquifer 

system wells and springs are typically very low, except where very localized 

sources—such as concentrated animal-feeding operations or malfunctioning septic or sewage systems—are present. Ammonia typically converts to 

nitrate before it reaches the aquifer.

Orthophosphate (dissolved, measured as P) ground water values for 

all fi ve planning units are at or near historical background concentrations, 

except for surfi cial aquifer system values in the Middle Coastal Planning 

Unit; however, this was based on samples from only two wells. Springs 

values were also near historical background concentrations, except for a 

median value of 0.07 mg/L from two springs in the Anclote River Planning Unit. Observed phosphorus levels in the basin’s surfi cial and Floridan aquifer wells may, in some cases, be associated with pollutant sources 

but are probably mainly associated with naturally phosphatic material in 

Water Quality Assessment Report: Springs Coast 13
the aquifers. Because it is the limiting nutrient in many of these systems, 

 however, phosphorus remains a parameter of interest.

DO values from both surfi cial and Floridan aquifer system wells were 

suboptimal by surface water standards but relatively normal for ground 

water, with surfi cial values generally higher than Floridan values, as 

expected, because ground water residence times in the surfi cial are generally 

shorter than in the Floridan.

Crystal River/Kings Bay Planning Unit

While no surface waters in the planning unit are listed as impaired for 

nutrients or DO, there are serious ecological imbalances in Kings Bay and 

Crystal River associated with nutrients in spring discharges—in particular, the increasing occurrence of the invasive plant species Hydrilla sp. 

and the alga Lyngbya wollei, and the decline of native submerged aquatic 

plants. Historical water quality data from Kings Bay springs show that 

nitrate concentrations in the early 1900s were 20 times lower than they are 

now. Ground water discharge from area springs is responsible for about 

94 percent of the total nitrogen and 84 percent of the total phosphorus 

entering Kings Bay, and the widespread use of inorganic fertilizers on 

lawns and golf courses is mainly responsible for the nitrate in ground water. 

Additional nitrate contributions may accompany future development in 

the Crystal River area and its springshed. Nitrate-enriched ground water 

plumes from northern and east-central Citrus County are predicted to 

reach the Kings Bay Springs Group by about 2010, and there is anomalous 

high local aquifer recharge in the intensively developed Beverly Hills area, 

about 8 miles from Kings Bay. 

Homosassa River Planning Unit 

No surface waters in the planning unit are listed as impaired for 

nutrients or DO; however, there are ecological imbalances in the Homossassa River (algal blooms and accumulation) caused by nutrients from 

springs. Nitrate concentrations in the Homossassa Springs Group have 

increased signifi cantly since the 1970s, and nutrient concentrations in the 

three springs that supply the Homosassa River indicate that all three likely 

receive signifi cant recharge from the larger springshed. The principal 

sources of nitrate in Homosassa and other spring complexes to the south 

come from fertilizer use in residential areas and golf courses. 

Chassahowitzka River Planning Unit

No surface waters in the planning unit are currently listed as impaired 

for nutrients or DO, but similar nutrient-related ecological imbalances 

are present as in the other Springs Coast spring systems. Nitrate levels 

have risen twelvefold since the mid-20th century and are over 60 times 

more than historical statewide background concentrations in the Floridan 

aquifer. Residential and golf course fertilization are the principal sources 

of nitrate in Chassahowitzka and other spring complexes to the north and 

south. Numerous quarries excavated into limestone in the springshed, 

along with natural karst features in the Brooksville urban area, increase 

potential recharge directly into the Floridan aquifer.

14 Water Quality Assessment Report: Springs Coast
Middle Coastal Planning Unit

Although no surface waters in the planning unit are currently listed as 

impaired for nutrients or DO, similar nutrient-related ecological imbalances 

are present in Weeki Wachee Springs and the Aripeka Springs Group as 

in the other Springs Coast spring systems—particularly in Weeki Wachee 

Springs, which has the highest nitrate concentrations in the Springs Coast 

basin. The nitrate mainly comes from inorganic sources in the immediate area of the springs, principally residential and golf course fertilizers. 

The increase in nitrates in Weeki Wachee Springs since the 1940s mirrors 

the growth in the area’s population and the development of large, coastal 

 residential subdivisions adjacent to Weeki Wachee in Hernando County.

Anclote River/Coastal Pinellas County Planning Unit

Unlike the planning units to the north, there are few known springs 

in this unit, and the ones present are of low magnitude—these include 

Tarpon, Health, and Crystal Beach Submarine Springs. Fourteen waterbodies are listed as impaired for nutrients (chlorophyll a or historical 

 chlorophyll) and 9 are listed as impaired for DO. The largest ground water 

contribution to these waterbodies likely comes from the surfi cial aquifer via 

seepage, rather than from the Floridan aquifer via springs. 

WBIDs 1440A (Spring Bayou Creek) and the adjacent WBID 1508 

(Klosterman Bayou Run Tidal) are both listed as impaired for low DO and 

elevated nutrients. The DO listing is based on high biochemical oxygen 

demand (BOD). The EPA has published a TMDL for Klosterman Bayou 

Run Estuary calling for nutrient reductions for total nitrogen and total 

phosphorus. WBID 1538 (Curlew Creek Estuary) is listed for elevated 

fecal coliforms and elevated nutrients. 

A number of WBIDs in the western half of the Pinellas Peninsula are 

listed for high nutrients and low DO: WBID 1567 (Stevenson Creek), 

WBID 1668A (St. Joe Creek), WBID 1668B (Pinellas Park Ditch No. 5), 

WBID 1668E (St. Joe Creek Tidal Estuary), and WBID 1709F (Frenchmann’s Creek Basin). Two of these (WBIDs 1668A and 1668B) have 

TMDLs set by the EPA. All are listed as high- or medium-priority for 

TMDL development. In each case, total nitrogen and phosphorus are 

elevated compared with expected values.

20 Water Quality Assessment Report: Springs Coast
Chapter 1: Introduction

Total Maximum 

Daily Load

The maximum amount 

of a given pollutant that a 

waterbody can assimilate 

and remain healthy, such that 

all of its designated uses are 

met.

Purposes and Content of the Assessment 

Report

The Florida Department of Environmental Protection (Department) 

is implementing a statewide watershed management approach for restoring 

and protecting water quality and addressing Total Maximum Daily Load 

(TMDL) Program requirements. Under Section 303(d) of the 1972 federal 

Clean Water Act and the 1999 Florida Watershed Restoration Act (FWRA) 

(Chapter 99-223, Laws of Florida), TMDLs must be developed for all 

waters that do not meet their designated uses (such as drinking water, recreation, and shellfi sh harvesting) and are thus defi ned as impaired.

TMDLs will be developed, and the corresponding reductions in pollutant loads allocated, as part of the watershed management approach, which 

rotates through the state’s 52 river basins over a 5-year cycle. Extensive 

public participation from diverse stakeholders in each of these basins is 

crucial in all phases of the cycle.

A Status Report published during Phase 1 of the watershed management cycle provided a Planning List, or preliminary identifi cation, of 

potentially impaired waterbodies in the Springs Coast Basin. A copy of the 

report can be found at http://www.dep.state.fl .us/water/tmdl/stat_rep.htm 

(under the Group 5 basins).

This Assessment Report, which updates the information in the Status 

Report, incorporates data collected from the Department’s strategic monitoring and gathered from other agencies and groups during Phase 2 of the 

watershed cycle. The report contains a Verifi ed List of impaired waters 

required by the FWRA and Section 303(d) of the federal Clean Water Act, 

for which TMDLs must be developed and implemented. It also describes 

the results of a preliminary ground water quality assessment and discusses 

priorities for further evaluation, as well as resource priorities and proposed 

actions. (See Noteworthy for a description of the contents of the Assessment Report, by chapter.)

Based on the assessment results, 57 waterbodies or waterbody segments 

in the Springs Coast Basin are verifi ed impaired for 1 or more parameters. 

TMDLs must be developed for these waters, unless the impairment is documented to be a naturally occurring condition that a TMDL cannot abate, 

or unless a management plan is already in place to correct the problem.

This report is intended for distribution to a broad range of potential 

stakeholders, including decision makers in federal, state, regional, tribal, 

and local governments; public and private interests; and citizens.

The Verifi ed List is required by Subsection 403.067(4), Florida 

 Statutes, and Section 303(d) of the federal Clean Water Act. The Department has adopted the Verifi ed List of impaired waters in accordance 

Water Quality Assessment Report: Springs Coast 21
with the FWRA and Identifi cation of Impaired Surface Waters Rule 

(Rule 62-303, Florida Administrative Code). The U.S. Environmental 

Protection Agency (EPA) has also approved this list as the current 303(d) 

list of impaired waters for the basin, so called because it is required under 

Section 303(d) of the Clean Water Act. 

The fi rst 303(d) list, which was required by the EPA in 1998, is to 

be amended annually to include basin updates. Florida’s 1998 303(d) list 

included a number of waterbodies in the Springs Coast Basin.

This Assessment Report follows the EPA’s guidance for meshing 

Clean Water Act requirements for Section 305(b) water quality reports 

and Section 303(d) lists of impaired waters. The integrated water quality 

assessment is used to identify the status of data suffi ciency, the potential 

for impairment, and the need for TMDL development for each waterbody or waterbody segment in the basin. Tables 3.5 through 3.9 in 

 Chapter 3 provide an integrated assessment for the Springs Coast Basin, by 

 planning unit.

Appendix A describes the legislative and regulatory background for 

TMDL development and implementation through the watershed management approach, and briefl y explains the TMDL Program. Background 

information on the Department’s TMDL Program, the process of TMDL 

development and implementation, lists of impaired and potentially 

impaired waters, and assessments for other parts of the state is available at 

http://www.dep.state.fl .us/water/tmdl/index.htm.

Stakeholder Involvement

The FWRA requires the Department to work closely with stakeholders to develop and implement TMDLs. Stakeholder involvement in the 

TMDL process will vary with each phase of implementation to achieve 

different purposes (Table 1.1). 

The Department will work cooperatively with a number of key stakeholders and initiatives to develop, allocate, and implement TMDLs in the 

Springs Coast Basin. These include the Southwest Florida Water Management District (SWFWMD); SWFWMD’s Crystal River/Kings Bay 

Surface Water Improvement and Management Program; Pasco, Hernando, 

Citrus, and Pinellas Counties; and the municipalities of Port Richey, New 

Port Richey, Weeki Wachee, Brooksville, Crystal River, Tarpon Springs, 

Palm Harbor, Dunedin, Clearwater, Largo, and Gulfport.

22 Water Quality Assessment Report: Springs Coast
Watershed Management Cycle Nature of Stakeholder Involvement

Phase 1: 

Preliminary

Evaluation

Close coordination with local stakeholders to conduct a preliminary basin water 

quality assessment, inventory existing and proposed management activities, 

identify management objectives and issues of concern, develop a Strategic 

Monitoring Plan, and produce a preliminary Status Report that includes a Planning List of potentially impaired waters

Phase 2:

Strategic Monitoring

and Assessment

Cooperative efforts between the Department and local stakeholders to collect additional data; enter data into STORET (the EPA’s national water quality 

STOrage and RETrieval database); complete the water quality assessment; produce a final Assessment Report that includes a Verified List of impaired waters 

for Secretarial adoption; and provide an opportunity for stakeholders to document reasonable assurance (for Department review) that existing or proposed 

management plans and projects are adequate to restore water quality without 

the establishment of a TMDL

Phase 3:

Development and

Adoption of TMDLs

Coordination with stakeholders to discuss TMDL model framework, including 

model requirements, parameters to be modeled, model endpoints, design run 

scenarios, and preliminary allocations; communication of science used in the 

process; public workshops for rule adoption of TMDLs

Phase 4:

Development of Basin 

Management Action Plan 

Broad stakeholder participation in developing a Basin Management Action Plan 

(B-MAP) (including detailed allocations and implementation strategies), incorporating it into existing management plans where feasible; public meetings 

during the planning process

Phase 5:

Implementation of Basin 

Management Action Plan

Emphasis on implementing the B-MAP, other voluntary stakeholder actions, 

and local watershed management structures; Department will continue to 

provide technical assistance, fulfill oversight responsibilities, and administer 

National Pollutant Discharge Elimination System point and nonpoint source 

permits

The Watershed Management Cycle in 

the Florida Department of Environmental 

Protection’s Southwest District

Figure 1.1 shows the order in which the Department’s Southwest 

District basins will be evaluated under the watershed management cycle. 

These groups are identifi ed according to a U.S. Geological Survey classifi cation system using hydrologic unit codes.

Tampa Bay, a Group 1 basin, was the fi rst basin in the district to 

undergo a preliminary assessment in 2000. A preliminary assessment for 

the Group 2 basin, Tampa Bay Tributaries, was completed in 2001. The 

Group 3 basin, Sarasota Bay–Peace–Myakka, was assessed on a preliminary 

basis in 2002. Similarly, a preliminary assessment for the Group 4 basin, 

Withlacoochee, was initiated in 2003, and the Group 5 preliminary assessment for the Springs Coast Basin was begun in 2004. In 2005, the cycle 

resumed with the Group 1 basin, Tampa Bay.

Chapter 2: Basin Overview

Basin Setting

The Springs Coast Basin encompasses parts of Pasco, Hernando, 

Citrus, and Pinellas Counties in west-central Florida. It is bounded on 

the west by the Gulf of Mexico and on the east by the Brooksville Ridge, 

a sandy remnant of previous higher sea levels, characterized by porous 

limestone (karst) geology, with wetlands in low-lying areas and scattered 

sinkhole lakes.

The basin covers about 1,052 square miles, or 673,000 acres, not 

including an estuarine ecosystem that extends in a nearly unbroken swath 

along the entire shoreline. The estuary’s bays, rivers, salt marshes, seagrass meadows, oyster bars, and tidal fl ats cover approximately another 

97,911 acres, or 15 percent of the total basin area. The 6 major rivers in 

the basin—Crystal, Homosassa, Chassahowitzka, Weeki Wachee, Anclote, 

and Pithlachascotee—their springs, and their associated coastal aquatic 

resources are dominant features. Tidal fl uctuations affect all the springs, 

except for Weeki Wachee.

The coastline along the basin’s western edge is heavily vegetated, shifting from saltmarsh-dominated communities in the northern part of the 

basin to mangrove-dominated communities in the southern portion. The 

low elevation creates fl ooding even during moderate storms. The coast 

contains numerous tidal creeks and salt marshes, as well as isolated islands 

fringed with mangroves. There are very few natural sandy beaches.

Barrier islands parallel the Gulf coast from southern Pasco County 

southward to Tampa Bay. A number of passes, or inlets, connect the Gulf 

of Mexico with the estuarine waters between the barrier islands and the 

mainland.

The presettlement vegetation in inland areas of the Springs Coast Basin 

was dominated by open, fi re-maintained pine forests on sandy uplands and 

coastal terraces. Longleaf pine was the dominant tree, replaced by slash 

pine in wetter sites and near the coast, and by pond pine in the wettest 

inland sites. Wiregrass was the dominant ground cover, particularly in 

the longleaf pine forests. Other community types, such as sand pine, oak 

scrub, and mesic hammocks, were embedded in the pine forest. In lower 

areas, hydric hammocks, swamps, marshes, and other wetland communities 

predominated.

Despite a great deal of growth in the last 30 years, Citrus, Hernando, 

and Pasco Counties—which are covered by coastal swamps, dense woodlands, lakes, and pastures—have retained a rural character. However, these 

three counties are rapidly changing. Residential and commercial development has rapidly expanded along the narrow U.S. Highway 19 corridor 

Water Quality Assessment Report: Springs Coast 27
that runs between the coastal swamps and the upland forest of the Brooksville Ridge, extending from Crystal River/Homosassa Springs southward 

to New Port Richey. Pinellas County is mostly developed. Much of 

the region’s urbanization is relatively recent. Municipalities in the basin 

include Port Richey, New Port Richey, Weeki Wachee, Brooksville, Crystal 

River, Tarpon Springs, Palm Harbor, Dunedin, Clearwater, Largo, and 

Gulfport. 

The northern portion of the basin, in western Citrus County, contains 

a number of rapidly growing retirement communities. Dense networks 

of streets and platted lots are present in the north-central portion of the 

county. Although relatively few houses have been built, the potential 

 density of these developments at build-out is extremely high. Rapid 

development is occurring in the U.S. Highway 19 corridor between 

Crystal River and Homosassa. The extreme western portion of this 

area is characterized by sparsely populated coastal swamps and wetlands 

(mostly state or federally owned), and the area between Weeki Wachee and 

 Chassahowitzka remains relatively undeveloped. 

Much of the upland forest covering the Brooksville Ridge consists 

of the Withlacoochee State Forest, which is regularly logged and virtually uninhabited. The forest encompasses approximately 148,000 acres 

in Citrus, Hernando, Pasco, and Sumter Counties. The largest tract, 

comprising approximately 43,000 acres, is in central Citrus County; the 

majority of this tract (approximately 30,000 acres) lies inside the Springs 

Coast Basin. Northeast of the forest, the city of Inverness, while not in the 

basin, supports a large residential community, commercial development, 

and recreational land uses.

The central portion of the basin, in western Hernando County, also 

contains a number of rapidly growing communities, characterized by 

moderately dense residential and commercial development. In the vicinity 

of Spring Hill and Weeki Wachee, residential development occupies a large 

portion of the area between U.S. Highway 19 and the Brooksville Ridge, 

particularly between State Road (S.R.) 50 and County Line Road. Spring 

Hill, with about 60,000 residents, is the largest of the area’s subdivisions. 

Pasture and forests are prevalent over the central and eastern portions of 

the central basin. The city of Brooksville, in the east-central portion of the 

basin, is characterized by residential and commercial land uses. Limestone 

mining is a major land use northwest of Brooksville.

The south-central portion of the basin, in western Pasco County, 

contains a widespread mixture of residential and commercial development, 

pasture, forest, and wetlands. The extreme western portion of the basin 

in Pasco County is characterized by coastal hardwood forests and swamps. 

The U.S. Highway 19 area, along the Gulf coast, contains densely developed residential and commercial areas. The central and eastern portions 

of the basin in Pasco County contain pasture, forest, open land, numerous 

lakes and wetlands, and some scattered row and tree crops.

The southern part of the basin encompasses western Pinellas County, 

from the Anclote River southward to Gulfport and Long Key, and eastward to S.R. 19. (The eastern side of the peninsula lies within the Tampa 

Bay Basin [a Group 1 basin] and was addressed earlier in the watershed 

28 Water Quality Assessment Report: Springs Coast
 management cycle.) Pinellas County, which is already 95 percent built out, 

has the highest population density in the state and the Southwest Florida 

Water Management District (SWFWMD). Many of the barrier islands 

bordering the Gulf of Mexico are also very densely developed; residential communities in these areas include Indian Shores, Redington Beach, 

Madeira Beach, Treasure Island, and St. Pete Beach. 

On the mainland, the largest cities in western Pinellas County are 

Tarpon Springs, Palm Harbor, Dunedin, Clearwater, Largo, and Gulfport. Major waterbodies include the Anclote River, Anclote Anchorage, 

Intra coastal Waterway, Lake Seminole, Bear Creek, Joe’s Creek, and Long 

Bayou. The Intracoastal Waterway has different names along its length, 

including St. Joseph Sound, Clearwater Harbor, the Narrows, and Boca 

Ciega Bay. The Cross Bayou Canal traverses the peninsula in a southwesterly direction from Old Tampa Bay to Cross Bayou, which then fl ows 

into Boca Ciega Bay.

Beginning in the 1920s, numerous waterfront areas in Pinellas County, 

including Clearwater Harbor and Boca Ciega Bay, were fi lled for residential 

and commercial development and contain extensive seawalls. From 1950 

to 1965, about 20 percent of the surface area of Boca Ciega Bay was fi lled. 

Most aquatic systems in these areas have deep channels that restrict seagrass 

growth, and water quality is typically poor.

The adjoining areas are also highly urbanized, with Pinellas County 

having the largest population per acre in the state (SWFWMD, 2001a). 

Many of the historic freshwater springs have dried up or have been contaminated by saltwater intrusion. Most of the wetlands in the basin are 

concentrated along the coast and occur in large, contiguous blocks.

Of the 194,500 acres in the basin dedicated to conservation, approximately 141,350 acres, or 73 percent, are sandwiched between the Gulf of 

Mexico and U.S. Highway 19. Three of the 4 large conservation tracts 

located inland of the coast (Citrus, Serenova, and Starkey) lie on the basin 

boundary, with large portions extending into adjoining basins. Conservation lands in the basin include 130,250 acres of state-owned lands, 

18,500 acres of SWFWMD-owned lands, 3,500 acres of county-owned 

lands, and nearly 1,000 acres of privately owned lands. 

The Chassahowitzka National Wildlife Refuge, established in 1931, 

comprises 31,000 acres of shallow saltwater bays, estuaries, brackish 

marshes, and tidal streams, with a fringe of hardwood swamps. Accessible 

only by boat, the refuge provides habitat for approximately 250 species of 

birds, over 50 species of reptiles and amphibians, and at least 25 different species of mammals. Endangered and threatened species found in the 

refuge include manatees, sea turtles, and bald eagles.

The Crystal River National Wildlife Refuge, established in 1983 and 

located in Citrus County, comprises 20 islands and several small parcels 

of land, surrounded by the crystal-clear, spring-fed waters of Kings Bay. 

Six hundred million gallons of fresh water fl ow daily from more than 

30 natural springs in the refuge. The water fl owing from the springs 

remains at a constant 72°F. The springs are Florida’s most signifi cant 

 natural warmwater refuge for the endangered West Indian manatee and 

provide critical habitat for the Crystal River herd, which makes up about 

Water Quality Assessment Report: Springs Coast 29
25 percent of the country’s manatee population. They also provide habitat 

and protection for numerous other wildlife species.

Anclote Key, the northernmost barrier island in the basin, comprises 

the Anclote Key Preserve State Park. The island is still expanding and 

has increased in size by about 30 percent since 1957. Just to the east of 

Anclote Key lies Anclote Anchorage, a shallow area containing seagrass 

beds that provides breeding habitat for numerous marine species, including 

threatened and endangered animals such as sea turtles and the West Indian 

manatee. The Anclote National Wildlife Refuge encompasses the waters 

between Anclote Key and the mainland. South of Anclote Anchorage is 

the Pinellas County Aquatic Preserve. The waters near the preserve attract 

numerous sponge divers.

Honeymoon Island State Park, Honeymoon Island State Recreation 

Area, and Caladesi Island State Park, which are undeveloped, are located 

along the Gulf coast in northern Pinellas/southern Pasco Counties. A 1921 

hurricane split Honeymoon Island in two, creating Hurricane Pass and 

Caladesi Island to the south. Honeymoon Island contains one of the few 

remaining south Florida stands of virgin slash pine, which provides osprey 

nesting sites. Both Honeymoon Island and Caladesi Island contain a 

number of important coastal plant communities such as mangrove swamps, 

seagrass beds, salt marshes, tidal fl ats, and sand dunes. Honeymoon Island 

has more than 208 plant species and a variety of shorebirds, including 

several threatened and endangered species. To the east of Honeymoon and 

Caladesi Islands lies St. Joseph Sound. It contains about 14,700 acres of 

seagrass, which is about 60 percent of the total seagrass acreage found in 

Tampa Bay.

Other major, publicly owned conservation areas in the basin include 

the following:

• The Chassahowitzka River and Coastal Swamps Area, comprising 

5,676 acres in western Citrus and Hernando Counties, contains the 

headwaters of the Chassahowitzka River and several tributaries and 

springs;

• Starkey Wilderness Park, an 8,069-acre tract, encompasses a portion 

of the headwaters of the Anclote River and a stretch of the Pithlachascotee River; and

• Weeki Wachee Preserve, a 9,000-acre area, is located on the Gulf 

coast in Hernando County. It contains the southernmost coastal 

hardwood hammock in western Florida. Limerock was mined in the 

southwest corner of the preserve from the 1940s through 1995.

The Crystal, Homosassa, Chassahowitzka, Weeki Wachee, Anclote, 

and Pithlachascotee Rivers and their associated coastal aquatic resources 

are popular for recreational activities such as swimming, scuba diving, 

snorkeling, fi shing, and boating. The U.S. Fish and Wildlife Service 

estimates that there were 91,515 visitors to the Crystal River National 

Wildlife Refuge and 33,340 visitors to the Chassahowitzka National 

Wildlife Refuge during 1996. Estimated visitors in 1997 at other nearby 

30 Water Quality Assessment Report: Springs Coast
sites include 250,000 at Homosassa Springs State Wildlife Park, 17,800 at 

the Chassahowitzka River Campground and Park, and 70,000 at the park 

at Pine Island.

In 1979, recreational fi shing trips and total number of fi sh landed 

on Florida’s west coast, including the Springs Coast Basin, exceeded that 

of Florida’s east coast and all other shorelines in the southeastern United 

States. The counties of the Springs Coast Basin, collectively, generated 

18,370 fi shing trips and landed over 4.5 million pounds of seafood in 1995. 

By 1999, the number of fi shing trips had grown to 19,753, with approximately 5.1 million pounds of seafood landed.

Agriculture was the historical economic base in Citrus, Hernando, and 

Pasco Counties. Several factors, however, including residential growth, 

the decreasing profi tability of farming, and freezes affecting the citrus 

industry, have had a dramatic effect. Today, these counties’ economies 

predominantly comprise retail trade, services, government, and construction. A signifi cant portion of Hernando County’s economy is still based on 

industry (including mining), cattle, and agriculture. Signifi cant limerock 

mining activities are carried out northwest of Brooksville. Western Pinellas 

County is largely urban, with some industrial development.

Table 2.1 lists the acreage and percentage of total acreage for land uses 

and land cover in the Springs Coast Basin. The table shows that over onethird of the basin (34 percent) is urban and built-up, followed by upland 

forests (26 percent) and wetlands (22.1 percent).

Table 2.2 lists historical and projected population fi gures for the basin. 

In 1980, the population of the four counties (Citrus, Hernando, Pasco, and 

Pinellas) was almost 1.02 million. By 1998, it had risen to more than 1.45 

million, and by 2020 is projected to grow to more than 1.8 million. There 

is also a large infl ux of seasonal residents into the basin during the winter 

months.

U.S. Highway 19 and U.S. Highway 41 are the major north-south corridors through Citrus, Hernando, Pasco, and Pinellas Counties. Continued 

Water Quality Assessment Report: Springs Coast 31
population growth in the basin was fueled by the construction of the 

 Suncoast Parkway (S.R. 589) during the 1990s. The 42-mile parkway, 

which extends from the Veterans Expressway in Tampa to U.S. Highway 

98 near the Hernando–Citrus County line, connects Hillsborough County 

with Pasco and Hernando Counties and provides an alternate north-south 

route through Florida’s west coast. In Pinellas County, S.R. 699 runs 

north- south through the barrier islands from Largo to St. Pete Beach.

Major east-west highways in the basin include S.R. 44, which connects 

the coastal areas around Crystal River with Inverness; S.R. 50, which originates in western Hernando County near Weeki Wachee and passes through 

Brooksville; and S.R. 52, which originates in western Pasco County.

Numerous other roads and highways crisscross the western Pinellas 

peninsula. Regional airports include the Crystal River and Hernando 

County Airports.

Coast Basin. Appendix B contains supplementary information on the 

basin’s ecology.

Surface Water Resources

The Springs Coast Basin contains numerous surface waterbodies. 

Surface waters, including lakes, streams, wetlands, and springs, occupy 

259 square miles, or about 24 percent of the total basin area. This section 

delineates the basin’s hydrology, describes the movement and management 

of water in the basin, briefl y describes the major characteristics of surface 

waters that infl uence water quality in the basin, and describes surface water 

classifi cations and special designations.

Physiography and Hydrology

There are three physiographic regions in the Springs Coast Basin, 

based on topographic relief and underlying sediments: the Coastal Swamp, 

Brooksville Ridge, and Gulf Coastal Lowlands. While it does not lie 

within the Springs Coast Basin, a fourth physiographic region, the Tsala 

Apopka Plain, also plays an important role in the basin’s water resources. 

The Coastal Swamp region parallels the coast, extending 2 to 5 miles 

inland. It is characterized by tidal marshes and coastal swamps. Elevations 

are less than 10 feet, and poorly drained, organic soils directly overlie the 

limestones of the Floridan aquifer system in much of the area.

The Brooksville Ridge, in the central portion of the basin, trends 

northwest-southeast through central Citrus County and eastern Hernando 

and Pasco Counties. The ridge measures approximately 17 miles wide in 

central Hernando County and reaches its southern terminus in northeastern Pasco County. Elevations range from 70 to about 275 feet. The ridge 

has an irregular surface due to karst activity, and elevations may vary more 

than 100 feet over short distances. The margins of the ridge are characterized by deep sandy soils, while the interior contains a mixture of poorly 

to well-drained sandy-clayey soils. The entire Brooksville Ridge region is 

underlain by a clayey unit that varies between 10 and 30 feet in thickness, 

but allows good hydraulic connection to the underlying Floridan aquifer 

system through karst features and fractures. The ridge supports upland 

communities such as longleaf pine sandhills, sand pine, and oak scrub, as 

well as numerous threatened and endangered species.

The Gulf Coastal Lowlands consists of a poorly drained, triangular 

area in the southern portion of the basin that lies between the Coastal 

Swamp region and the cliffs of the Pamlico Scarp on the west, and the 

Brooksville Ridge on the east. It varies from 2 to 8 miles wide, and elevations range from sea level to about 100 feet. The topography consists 

of relatively fl at coastal swamps, river valley lowlands, and rolling hills 

made up of eolian, or wind-sculpted, sand dunes. Soils comprise sands or 

clayey sands.

The Tsala Apopka Plain lies between the Brooksville Ridge and the 

Withlacoochee River within the recharge area of the coastal springs. It 

contains a large number of interconnected lakes that are divided by peninsulas and islands; these lakes are remnants of a much larger lake that 

once covered the entire Tsala Apopka Plain. Siliciclastic deposits cover the 

limestone surface, and elevations range from 35 to 75 feet. The soils are 

generally sandy and weakly cemented with organic matter.

Streams

In the northern part of the basin, the principal waterbodies are the 

coastal, spring-fed Crystal, Homosassa, Chassahowitzka, and Weeki 

Wachee Rivers. All 4 rivers originate from fi rst-magnitude springs near 

the coast, meaning that each spring discharges an average of 100 cubic feet 

34 Water Quality Assessment Report: Springs Coast
Figure 2.2: Surface Water Resources of the Springs Coast Basin

Water Quality Assessment Report: Springs Coast 35
per second (cfs) or more. These rivers are typically less than 10 miles in 

length. As a result, only a limited amount of runoff is channeled from the 

upper basin to the rivers. Hammock Creek, at Aripeka, is a coastal system 

formed by several lesser-magnitude springs and swamp discharge.

In the southern portion of the basin, surface water drains either 

directly to the Gulf of Mexico or to the Pithlachascotee (Cotee) or 

Anclote Rivers. 

The lack of rivers and streams in the interior of the Springs Coast 

Basin results from a well-developed underground drainage system in 

the underlying limestone. Most of the area has a well-developed karst 

 topography, with hundreds of shallow depressions, sinkholes, circular 

lakes and ponds, and active springs. Precipitation falling on the Brooksville Ridge rapidly moves underground through numerous sinkholes and 

 fi ssures, and begins moving toward the Gulf of Mexico through an extensive system of conduits.

Crystal River and Kings Bay are located in Citrus County approximately 60 miles north of Tampa. The tidally infl uenced Kings Bay is the 

headwater of the Crystal River, which forms at the northwest corner of 

the bay. Six miles west of Kings Bay, the river ends at the Gulf of Mexico. 

The Crystal River/Kings Bay system, the fourth largest of the 33 fi rst-

 magnitude springs in Florida, contains a cluster of at least 30 springs. 

While other spring systems in the state are also tidally infl uenced, the 

 presence of the 600-acre Kings Bay embayment makes this hydrologic 

system unique.

Like Crystal River, the Homosassa River is a coastal, spring-fed river 

and estuarine system located in west Citrus County. The river extends 

approximately six miles from its headwaters at Homosassa Springs to the 

Gulf of Mexico. The Homosassa’s major tributary is Halls River.

The Chassahowitzka River is located in southwestern Citrus County 

approximately six and one half miles south of Homosassa and just north of 

the Citrus/Hernando County line. The river is fed by numerous springs 

and fl uctuates seasonally with ground water levels. Crab Creek, Cabbage 

Creek, Baird Creek, Salt Creek, Potter Creek, Crawford Creek, Blue Run, 

Ryle Creek, and May Creek all fl ow directly to the Chassahowitzka River, 

while Chub Creek and Blind Creek fl ow to the Gulf of Mexico.

The Weeki Wachee River is located in southwest Hernando County, 

approximately 12 miles southwest of the city of Brooksville. Weeki Wachee 

Springs is the headwaters of the river and the largest of 9 springs associated 

with the Weeki Wachee system. The springs were developed as a commercial attraction featuring “live mermaids.” The Weeki Wachee River 

extends westward through approximately 7.5 miles of predominantly lowlands (coastal swamps and marshes) to the Gulf of Mexico. Its 2 principal 

tributaries are the Mud River and Jenkins Creek.

The Hammock Creek system includes several small springs clustered in a one-square-mile area in southwestern Hernando County, near 

 Aripeka. Hammock Creek, approximately one mile in length, is joined by 

several lesser tidal creeks before reaching the Gulf of Mexico at the town 

of Aripeka. The springs either discharge directly into Hammock Creek or 

36 Water Quality Assessment Report: Springs Coast
discharge into the lesser creeks fl owing into Hammock Creek. The creek’s 

water is brackish nearly to the headsprings.

The Pithlachascotee River starts in Hernando County as channeled 

fl ow through the Masaryktown Canal. It then fl ows southwest to its headwaters, Crews Lake, through an area of interconnected lakes and sinkholes 

in south-central Hernando County, near Brooksville. From there, it fl ows 

about 25 miles through a poorly defi ned channel to the Gulf of Mexico at 

Port Richey. The river includes both estuarine and freshwater reaches. As 

it fl ows, substantial amounts of water drain underground to the Floridan 

aquifer. The river has very low base fl ow. During low-fl ow conditions, 

most of its water comes from ground water seepage. During high-fl ow 

conditions, surface water runoff constitutes most of the fl ow.

The Pithlachascotee watershed contains numerous water table marshes 

and lakes, including Crews Lake. These fl uctuate with ground water levels 

and may disappear completely during dry spells or with heavy ground 

water pumping.

The Anclote River originates in swampy lowlands in south-central 

Pasco County, east of New Port Richey, and from there meanders in a 

southwesterly direction, entering the Gulf of Mexico just north of Tarpon 

Springs. The lower reach of the Anclote River is a tidal estuary that fl ows 

into Anclote Anchorage, a shallow area of seagrass beds to the east of 

Anclote Key. Tidal infl uences extend as much as 14 miles up the river. 

The mean depth of the lower river is just over 3 feet, except for a dredged 

shipping channel about 15 feet deep that extends from Tarpon Springs to 

the river mouth. Salinity at the river mouth ranges from 0.8 to 32.7 parts 

per thousand, depending on rainfall and tidal fl ows.

Springs

The Springs Coast Basin contains 4 major spring complexes, which 

occur because of the region’s karst geology. A spring complex is a group 

of springs, often spread out over several square miles, that are discharge 

points for ground water in a discrete ground water basin. Combined, these 

4 complexes discharge approximately 900 million gallons per day (mgd) 

from the Floridan aquifer system. Rainfall, which is the primary recharge 

mechanism for the aquifer, averages 56 inches per year.

Spring fl ow is a major discharge mechanism for the aquifer, accounting 

for 64 to 84 percent of the total recharge input. The Crystal River/Kings 

Bay Springs Complex, the largest such complex in the basin, discharges 

approximately 630 mgd. The three other major springs—Weeki Wachee, 

Chassahowitzka, and Homosassa—discharge 113, 90, and 68 mgd, respectively. Other large springs in the basin include Ruth Spring, Salt Spring, 

Little Springs, Bobhill Springs, Magnolia Springs, Horseshoe Spring, 

Salt Springs, Wall Springs, Crystal Beach Springs (which is located about 

1,000 feet offshore), and Tarpon Springs (which is tidally infl uenced and 

can reverse fl ow).

Water Quality Assessment Report: Springs Coast 37
Lakes

Including Crews Lake, which covers approximately 693 acres, there 

are approximately 137 lakes in the Springs Coast Basin, with a surface area 

totaling approximately 1,503 acres. Of this acreage, 555 acres are made up 

of lakes smaller than 10 acres. In addition to Crews Lake, other large lakes 

in the basin include Hunters Lake, Weeki Wachee Prairie Lake, Hog Pond, 

Grear Hope Pond, Tooke Lake, and Lake Seminole.

Most of the basin’s lakes, springs, and ponds occur in shallow depressions on the land surface. Their surface area varies considerably with 

seasonal changes in rainfall: they cover large areas during the wet season 

and, in some cases, dry up completely during the dry season or in times of 

drought. Many of these wetland areas are marshes rather than lakes. The 

marshes are hydraulically connected to the water table aquifer, and the 

fl uctuations in surface water elevation are directly related to changes in the 

water table.

Several lakes in the basin are directly connected to the underlying 

Floridan aquifer by sinkholes in the lake bottoms. Crews Lake, the largest 

of these waterbodies, has a sinkhole located in the north part of the lake. 

The lake level has varied seasonally at least since the mid-1800s. During 

very dry years, the lake has been completely drained through the sinkhole. 

Lake Seminole, which covers 980 acres and averages about 5 feet in 

depth, was formerly the upper reach of Long Bayou. In 1950, a dam was 

built across the bayou severing the hydraulic connection and eliminating 

tidal fl ushing.

Until 1967, Lake Tarpon, the largest lake in the county at 2,534 acres, 

was connected hydrologically to Spring Bayou, which fl owed into the 

Anclote River. However, the U.S. Army Corps of Engineers dammed the 

lake to control saltwater intrusion. The lake now discharges through an 

artifi cial control structure into Tampa Bay near the city of Safety Harbor.

Nearshore Estuary

The northern portion of the Springs Coast Basin has no classic estuaries, where brackish waters are separated from the ocean by physical barriers 

such as islands. In many ways, however, this coastal area functions like an 

estuary, with its shallow waters, abundant freshwater fl ows, and low-energy 

shoreline. Seagrass beds cover almost the entire nearshore area along the 

northern portion of the basin, and extensive oyster reefs are also present.

From the Anclote River southward to the mouth of Tampa Bay, a 

45-mile-long chain of barrier islands parallels the coast, creating sheltered, 

open saltwater areas and associated shallow-water features such as salt 

marshes, beaches, seagrass meadows, and tidal fl ats. Historically, drainage to these estuarine areas came mainly from sheet fl ow across the land 

surface, bayous, and small tidal creeks. This stretch of coastline, however, 

is now intensively developed and receives large amounts of drainage from 

urban stormwater systems. 

In the Springs Coast Basin, the nearshore estuarine area covers about 

996 acres. Although this region is a defi ning surface water feature in the 

basin, its signifi cance far exceeds its areal extent. It provides essential habitat for numerous fi sh and wildlife species, including nursery and juvenile 

38 Water Quality Assessment Report: Springs Coast
habitats for many recreational and commercial fi sh species. The economic 

value of commercial seafood harvests on Florida’s west coast consists of at 

least 95 percent estuary-dependent species.

The estuary’s wetland vegetation helps to maintain or improve water 

quality by fi ltering and assimilating many waterborne pollutants and 

stabilizing bottom sediments. It also provides a buffer between developed 

shorelines and the open waters of the Gulf of Mexico that can absorb some 

of the destructive impact of storm-generated winds and tidal surges. A 

long band of hydric hammock forest occurring just inland of the estuary 

provides additional protection to much of the shoreline of Hernando and 

Citrus Counties.

Surface Water Quality Classifications 

Florida’s water quality standards, the foundation of the state’s program of water quality management, designate the “present and future most 

benefi cial uses” of the waters of the state (Subsection 403.061[10], Florida 

Statutes [F.S.]). Water quality criteria for surface water and ground water, 

expressed as numeric or narrative limits for specifi c parameters, describe the 

water quality necessary to maintain these uses. Florida’s surface water is 

classifi ed using the following fi ve designated use categories:

Class I Potable water supplies

Class II Shellfi sh propagation or harvesting

Class III Recreation, propagation, and maintenance of a healthy, 

 well-balanced population of fi sh and wildlife

Class IV Agricultural water supplies

Class V Navigation, utility, and industrial use (there are no state 

 waters currently in this class)

All of the waters in the Springs Coast Basin are Class III, marine or 

fresh waters, except for a portion of Crystal River (waterbody identifi cation 

number 1341), which is a Class II water.

Special Designations

Outstanding Florida Waters

The following waterbodies in the basin have been given additional 

protection through designation as Outstanding Florida Waters (OFWs): 

Crystal River and Kings Bay, Chassahowitzka River, Crab Creek, Cabbage 

Creek, Baird Creek, Salt Creek, Potter Creek, Crawford Creek, Blue 

Run, Ryle Creek, May Creek, Chub Creek, Blind Creek, and Weeki 

Wachee River. In addition, all of the lakes and streams in Pinellas County 

are OFWs.

OFWs are designated for “special protection because of their natural 

attributes” (Section 403.061[27], F.S.). These waters are listed in Section 

62-302.700, Florida Administrative Code (F.A.C.). The intent of an OFW 

designation is to maintain ambient water quality, even if these designations 

are more protective than those required under the waterbody’s surface water 

classifi cation. Most OFWs are associated with managed areas in the state 

Water Quality Assessment Report: Springs Coast 39
or federal park system, such as aquatic preserves, national seashores, or 

wildlife refuges. Other OFWs may also be designated as “Special Waters” 

based on a fi nding that the waters are of exceptional recreational or ecological signifi cance, and are identifi ed as such in Rule 62-302, F.A.C.

Surface Water Improvement and Management Priority Waters

Crystal River/Kings Bay has been designated as a Surface Water 

Improvement and Management (SWIM) priority waterbody for restoration. The original SWIM plan for the river and bay was prepared and 

approved in 1989, and the plan was updated in 2000.

In 1987, the Florida legislature created the SWIM Program to restore 

waterbodies. The initial legislation identifi ed 6 priority waterbodies: Lake 

Apopka, Tampa Bay, Indian River Lagoon, Biscayne Bay, Lower St. Johns 

River, and Lake Okeechobee. Today, SWIM plans have been developed 

for 30 waterbodies statewide. The SWIM Program addresses a waterbody’s 

needs as a system of connected resources, rather than isolated wetlands or 

waterbodies. The state’s 5 water management districts work with federal, 

state, and local governments and the private sector to develop and implement SWIM plans to restore damaged ecosystems, prevent pollution from 

runoff and other sources, and educate the public.

Minimum Flows and Levels 

Table 2.3 lists the 1999 priority schedule for minimum fl ows and 

levels (MFLs) in the Springs Coast Basin. Of particular concern is the 

impact of ground water development on coastal spring discharges and 

freshwater fl ows to the coastal estuaries. The Springs Coast Basin is internally drained, and the upper Floridan aquifer is the primary source of water 

to its numerous coastal springs, which in turn are the principal source of

surface fl ow in the coastal rivers area. Approximately 1.3 billion gallons of 

water are discharged from the coastal springs daily.

Under the Florida Watershed Restoration Act (FWRA) (Chapter 373, 

F.S.), MFLs are the limit at which further water withdrawals will cause 

 signifi cant harm to the water resources of the area and related natural 

 systems. Consumptive use and alterations to their watersheds have reduced, 

or have the potential to reduce, the amount and timing of surface water 

being delivered. Projected increases in withdrawals also could reduce future 

fl ows and levels.

To help determine the amount of water that is available for environmental and human uses, the SWFWMD must determine MFLs. Lakes 

and aquifers have minimum levels. Minimum fl ows are set for rivers and 

streams.

Ground Water Resources

Aquifers

Geology

The geology of the Springs Coast Basin is relatively simple, with thick 

sequences of limestone exposed at or very near (10 to 20 feet) the land surface in the eastern and western portions of the basin. Where the limestone 

is near the land surface, the thin veneer of sediment covering the limestone 

consists of unconsolidated deposits of primarily quartz sand. These sands 

are marine terrace deposits and coastal dune trains. Dunes are prevalent in 

the Coastal Lowlands and along the fl anks of the Brooksville Ridge.

The limestone units include the Suwannee Limestone of Oligocene age 

and the Ocala Limestone of Eocene age. Underlying these exposed limestone units is the Avon Park Formation of Eocene age. The Avon Park Formation is the deepest formation containing potable water. The Suwannee 

and Ocala Limestones and the Avon Park Formation comprise the Floridan 

aquifer system in the basin.

In the Brooksville Ridge area, undifferentiated quartz sand and sediments of the Hawthorn Group overlie the Floridan aquifer system. The 

Hawthorn Group sediments were deposited in a variety of environments 

and consist of sand, silty sand, and waxy green clay. Phosphorite pebbles 

and fossil oyster bars are common. Between Brooksville and the Hernando–Citrus County line to the north, the Hawthorn sediments have largely 

been eroded off the Brooksville Ridge, and the limestone is exposed or near 

the land surface in many of the high areas.

Karst processes play a dominant role in moving ground water through 

the Floridan aquifer system in the basin. The four physiographic regions 

(the Coastal Swamp, Gulf Coastal Lowlands, Brooksville Ridge, and Tsala 

Apopka Plain) in or adjoining the spring recharge zone are areas of intensive karst development characterized by numerous sinkholes, a lack of surface drainage, and undulating topography. In karst areas, the dissolution of 

limestone creates and enlarges cavities along fractures in the limestone that 

eventually collapse and form sinkholes. Sinkholes capture surface water 

drainage and funnel it underground, which promotes further dissolution 

Water Quality Assessment Report: Springs Coast 41
of the limestone. This leads to the progressive integration of voids beneath 

the surface and allows larger and larger amounts of water to be funneled 

into the underground drainage system.

Dissolution is most active at the water table or in the zone of water 

table fl uctuation, where carbonic acid contained in atmospheric precipitation and generated by reaction with carbon dioxide in the soil reacts with 

limestone and dolostone. Because the elevation of the water table shifted in 

response to changes in sea level, many vertical and lateral paths have developed in the underlying carbonate strata in the basin. Many of these paths 

or conduits lie below the present water table and greatly facilitate ground 

water fl ow.

Surficial Aquifer System

The surfi cial aquifer system in the basin consists of quartz sand, silty 

sand, and clay. The surfi cial aquifer is most likely to occur as a distinct 

hydrostratigraphic unit along the Brooksville Ridge, where the low-

 permeability clays of the Hawthorn Group retard the downward movement 

of water into the Floridan aquifer system. The collapse of the underlying 

limestone, however, has produced numerous breaches in the clays that act 

as vertical conduits for the movement of water from the surfi cial to the 

Floridan aquifer system. The Hawthorn sediments are also not widespread 

between Brooksville and the Hernando–Citrus County line.

In areas where saturated sand lies directly above the limestone, water 

in the sand is hydraulically connected to the Floridan aquifer. Since the 

majority of the basin has no extensive confi ning layer, most of the region 

does not have a surfi cial aquifer, although surfi cial sands are present.

Floridan Aquifer System

The Floridan aquifer system is divided into two major hydrostratigraphic horizons: the upper Floridan, which contains potable water, and 

the lower Floridan, which is saline. This discussion focuses on the upper 

Floridan aquifer, which is the principal source of water for the springs in 

the basin, as well as domestic, agricultural, and industrial supplies.

The thickness of the potable water zone in the Floridan aquifer in the 

basin ranges from more than 900 feet in south-central Pasco County, to 

less than 200 feet along the Withlacoochee River in southeastern Citrus 

County, to less than 100 feet along the coast. A general uniform thinning 

of the upper Floridan aquifer’s potable zone occurs from south to north 

across the basin. The vertical extent of potable ground water inland is 

controlled by the occurrence of gypsum-bearing carbonates of the middle 

confi ning unit, and the presence of sulfate-rich waters derived from the 

dissolution of sulfate minerals at the top of the unit. The average thickness 

of the potable zone in the Floridan aquifer is 400 to 600 feet in Hernando 

County and 200 to 300 feet in Citrus County.

The Springs Coast Basin is mostly contained within the Northern 

West-Central Florida Groundwater Basin. The southwestern portion of 

the basin is situated in the Central West-Central Florida Groundwater 

Basin. Ground water in both basins derives from rainfall. Approximately 

1,700 mgd of ground water discharge from 27 coastal springs.

42 Water Quality Assessment Report: Springs Coast
The recharge potential for the Floridan aquifer in the basin is primarily controlled by the thickness and composition of the surfi cial sediments 

overlying the aquifer and the presence of karst topography. Other factors 

affecting recharge rates include the development of surface drainage; variations in head gradients between surface water, the surfi cial aquifer system, 

and the Floridan aquifer system; and aquifer permeability.

Generally, high recharge rates occur where limestone is near the land 

surface, or where overlying sediments are lacking in low-permeability confi ning materials. The presence of sinkholes, with their associated internal 

drainage of surface water, also induces higher recharge to the Floridan 

aquifer system. Lower recharge rates occur where confi ning materials 

overlying the aquifer retard the downward vertical movement of water, or 

where an upward gradient is present between the Floridan and surfi cial 

aquifer systems.

Recharge is variably low to nonexistent in the Coastal Swamp region, 

with estimated recharge values of -9 inches (discharge) to 11 inches per 

year. This is primarily an area of regional Floridan aquifer discharge, with 

only localized recharge over very short distances contributing to spring 

discharge. Recharge in the Tsala Apopka Plain is similarly low, due to a 

diminished downward vertical gradient between surface waters or the surfi -

cial aquifer and the Floridan aquifer. Ground water discharge also occurs 

along sections of the Withlacoochee River south and east of Tsala Apopka.

Accordingly, recharge estimates in the region range from less than 

1 inch to 9 inches per year. Moderate to high recharge occurs in the 

Coastal Lowlands and Brooksville Ridge physiographic regions. Potential recharge of 3 to 16 inches occurs in the Coastal Lowlands, with 7 to 

11 inches reported over land areas near the spring complexes.

Recharge estimates in the Brooksville Ridge region are very high, ranging from 9 to 22 inches per year, because this area contains karst terrain 

with internal drainage to the upper Floridan aquifer. Sinkholes are abundant, the land surface is generally very well drained, and the water table is 

relatively deep. Surface waters are not abundant, and there are no permanent streams or extensive wetlands. These factors maximize recharge, 

because infi ltration is rapid and surface runoff is nonexistent.

The vulnerability of the Floridan aquifer system in the basin correlates 

with recharge estimates. Because of the porous karst terrain, the potential 

for ground water contamination in the Brooksville Ridge area is very high. 

The rest of the basin also has a high ground water contamination potential. 

This does not indicate that ground water contamination will occur, only 

that it could occur if pollutant sources were present. Potential pollutant 

sources in the Springs Coast Basin include landfi lls, borrow pits, stormwater ponds, septic systems, wastewater treatment facilities, and urban 

and agricultural runoff. Ground water may also be contaminated through 

the inadvertent release or spilling of industrial or agricultural chemicals or 

waste products.

Water Quality Assessment Report: Springs Coast 43
Ground Water–Surface Water Interactions 

The Brooksville Ridge is an area of high elevation, characterized by 

rolling sandhills, that extends along the eastern side of the Springs Coast 

Basin from north-central Citrus County south-southeastward through 

central Hernando County and southeast through east Pasco County. 

Although the regional confi ning unit between the surfi cial aquifer and 

upper Floridan aquifer is thickest along the Brooksville Ridge, its integrity is variable in this area. Karst activity has created large breaches in the 

confi ning unit, many of which appear at the surface as relatively deep lakes. 

Due to the large head differences between the surfi cial and upper Floridan 

aquifers, the presence of sinkholes that breach the confi ning unit, and the 

availability of thick, surfi cial sands that act as reservoirs, recharge along the 

Brooksville Ridge can be quite high. 

In karst areas such as this, the formation of a unique type of sinkhole 

called a solution pipe is common. Solution pipes are formed by the collapse 

of surfi cial material into long, vertical cavities that have been dissolved in 

the upper portion of the limestone. In most cases, a natural plug of sands 

and clays caps the solution pipes. If the cap is washed out, however, the 

resulting solution pipe sinkhole can act as a direct conduit for the movement of stormwater into the upper Floridan aquifer. Solution pipe sinkholes often form in the bottom of stormwater retention basins, where the 

capping plug is thinner. Catastrophic failure can occur if the increased 

hydraulic pressure exceeds the capacity of the capping plug. Solution pipes 

act as natural drainage wells and can drain large stormwater basins.

Most of the springs in the basin lie in or near the freshwater/saltwater transition zone, a brackish zone in the upper Floridan aquifer where 

 seaward-moving fresh water meets landward-moving salt water. As a 

result of their proximity to the transition zone, many of the basin’s springs 

discharge brackish water. The high salt content of many of these springs 

indicates that Gulf water has intruded through interconnected solution 

conduits gulfward of the springs. In general, springs located farther inland 

are farther from the transition zone and therefore have fresher water. A 

sharp boundary is not present in coastal aquifers because of mechanical dispersion and tidal or water level fl uctuations caused by changes in recharge 

or pumpage over time. Instead, a dynamic equilibrium is established that 

causes fresh water and salt water to mix and form a transition zone.

There are approximately 140 active wastewater treatment facilities 

in the ground water basins of the Crystal, Homosassa, Chassahowitzka, 

Weeki Wachee, and Aripeka Spring Complexes. These facilities have a 

total permitted capacity of 15.6 mgd, and their average volume of processed 

wastewater is approximately 9.2 mgd. Effl uent from treatment facilities 

is disposed of in several different ways. A majority use percolation ponds. 

Several studies in the mid-1990s documented that some effl uent percolation ponds in the basin drain extremely rapidly because they have highly 

porous bottoms composed of clean, fi ne-grained fi lter material. Since 

low-permeability confi ning units are either not present in the basin, or are 

frequently breached by sinkholes, treated effl uent can rapidly percolate 

directly into the Floridan aquifer system.

44 Water Quality Assessment Report: Springs Coast
In Citrus County, levels of nitrate exceeding drinking water standards 

were detected in numerous wells monitoring large effl uent percolation 

ponds. The effect of effl uent on the Homosassa and Chassahowitzka 

Spring Complexes is probably insignifi cant, however, because the amount 

of nitrogen contributed from effl uent in these ground water basins is low. 

In the Weeki Wachee ground water basin, the nitrogen from effl uent is 

high, but the treatment plants are dispersed over a very large area and most 

are located far from the spring. Also, the low nitrogen isotopic ratios in 

the springs indicate an inorganic source, most likely from fertilizer application. In the Aripeka ground water basin, the nitrogen from effl uent may 

contribute some nitrogen to the Aripeka Springs Complex, because the 

Hudson wastewater treatment plant is located approximately 3.5 miles 

from the spring. However, the plant is probably not the dominant nitrogen 

source because, like Weeki Wachee Springs, the low nitrogen isotopic ratios 

indicate an inorganic fertilizer source.

Ground Water Usage

Water supply in the Springs Coast Basin is derived principally from the 

upper Floridan aquifer. In 1996, ground water use in the basin was estimated at 80 mgd, or 94 percent of total water use, compared with 5.5 mgd 

of surface water. Hernando County accounted for about 45 percent 

(38.3 mgd) of total water use, compared with 40 percent for Pasco County 

and 15 percent for Citrus County. The largest use of water was for potable 

supply (57.9 mgd, or 68 percent). About 30.8 mgd are withdrawn from 

within Pasco County for potable supply. The basin contains more than 

500 public supply wells, according to the Florida Department of Environmental Protection’s (Department’s) Public Water System (PWS) Database. 

The largest wellfi elds are operated by Hernando County West Utilities 

(33 wells), Pinellas County Utilities (31 wells), Hudson Waterworks 

(17 wells), and Tampa Bay Water (17 wells).

Public supply constitutes the greatest water use in the basin, with 

mining activities a distant second. In addition, 2 wellfi elds in Pasco 

County serve as a major source of public water supply for the Tampa Bay 

area (which lies outside the basin) through Tampa Bay Water: the Cross 

Bar Ranch and North Pasco wellfi elds. Rates of ground water withdrawals from these facilities in 1996 were 20.2 mgd and 1.6 mgd, respectively. 

Most of the area supplying Tampa Bay Water that falls within the Springs 

Coast Basin is considered unsuitable for future ground water development. 

In some areas, such as Pasco County, wetlands are drying up as a result of 

pumping. Large ground water withdrawals in coastal Pasco, Hernando, 

and Citrus Counties have also increased saltwater intrusion and the contamination of water supplies.

In 1998, the SWFWMD conducted a water supply assessment for 

4 regions within its boundaries. The majority of the Springs Coast Basin 

was contained in the northern water supply planning region, which 

includes Citrus, Hernando, and Sumter Counties and portions of Marion, 

Levy, and Lake Counties. Water supply demands for the northern region 

were projected to grow from 186.4 mgd in 1995 to 246.1 mgd in 2020, an 

increase of about 60 mgd (32 percent).

Tables 2.4 through 2.7 list estimated past and projected water use for 

Citrus, Hernando, Pasco, and Pinellas Counties, respectively.

Water Use Caution Areas 

In 1989, the SWFWMD designated the Northern Tampa Bay Water 

Use Caution Area (WUCA), which includes the southernmost portion of 

the Springs Coast Basin (southern Pasco County and Pinellas County).

Under Section 373.036, F.S., and Subsection 62-40.520(1), F.A.C., 

each water management district in the state must identify WUCAs in 

which potential water shortages, considerable reductions in water levels,

saltwater intrusion, or other degradations may occur within 20 years, and 

must develop management plans to address its water resource problems. 

In these areas, existing and anticipated sources of water and conservation 

efforts may not be adequate to supply water for all existing legal uses and 

reasonably anticipate future needs, and still sustain water resources and 

related natural systems. Five constraints are considered in establishing 

these WUCAs:

• Impacts to native vegetation, primarily wetlands;

• Impacts to minimum fl ows and levels, primarily spring fl ows;

• Impacts to ground water quality in terms of increased saltwater 

intrusion;

• Impacts to existing legal users; and

• Failure to identify a source of supply for future development.

Ground Water Quality Issues

Overall ground water quality in the Springs Coast Basin is very good. 

However, point and nonpoint source threats to ground water quality exist 

and may become greater concerns with population growth and changing 

land uses. A variety of waste sites, some of which are regulated by state and 

federal programs, threatens the potable ground water supply. However, 

the quality of ground water that discharges to springs and estuaries is also 

threatened by point sources of wastewater, as well as nonpoint source activities that add nutrients to the Floridan aquifer.

Potential Threats to the Potable Water Supply

Ground water quality in the basin is affected in some areas by contaminant sources that are being addressed by several programs managed by the 

Department. Figure 2.3 shows known sources of contamination in the 

Springs Coast Basin. Department databases include the following sites or 

facilities: 

Water Quality Assessment Report: Springs Coast 47
Figure 2.3: Ground Water Usage and Known Contaminant Sources in the Springs Coast Basin

48 Water Quality Assessment Report: Springs Coast
• Federal Superfund Sites: One Superfund site in the basin, Stauffer 

Chemical in Tarpon Springs, is on the National Priority List.

• State Waste Cleanup Program Sites: There are two state Waste 

Cleanup Program sites in the basin: Alaric, Inc. and APF Industries.

• Petroleum Contamination Monitoring Sites: The basin contains 

more than 1,600 known petroleum contamination monitoring sites. 

These sites are undergoing ground water monitoring, and some 

are undergoing cleanup. Public or private drinking water supplies 

affected by petroleum contamination are protected in one of several 

ways: (1) the affected well is decommissioned and water is provided 

from an alternative source, (2) treatment is provided at the water 

plant, or (3) for affected residential wells, activated carbon fi lters 

are installed to remove the contamination and meet drinking water 

standards.

• State Dry Cleaning Program Sites: About 77 dry cleaning program sites have been identifi ed in the basin. Affected water supplies 

are being addressed as described for petroleum facilities.

• Brownfi eld Sites: Two brownfi eld sites have been identifi ed: the 

Clearwater Area and the Young Rainey Star Center Area.

• Delineated Areas of Ground Water Contamination: Eight areas 

of ground water contamination have been identifi ed by the Department’s Delineation Program (regulated under Rule 62-524, F.A.C., 

New Potable Water Well Permitting in Delineated Areas). The 

contaminant of concern is ethylene dibromide, an agrichemical and 

petroleum fuel additive that is now banned from use.

Sources of Nutrients Threatening Ground Water Quality and Springs

A major concern in the Springs Coast Basin is the increased nitrate 

loadings observed in the major springs groups. While the dominant source 

of nitrate found in the springs is inorganic in nature (i.e., originating from 

the residential and commercial use of fertilizers), organic sources may still 

contribute signifi cant quantities in other areas, or on a local scale. The 

agricultural application of fertilizers is also a potential source of inorganic 

nitrogen in the basin. Sources of organic nitrogen include sewage effl uent 

disposal, the land disposal of sewage sludge or treated wastewater, effl uent 

from septic tanks, agricultural activities (poultry, dairy, and cattle), and 

the application of potentially nutrient rich (with nitrogen and phosphorus) 

reclaimed water as irrigation.

Nutrient concentrations in the Floridan aquifer system in the basin are 

typically very low. Nitrate is easily leached into ground water, where it disperses through the aquifer system. Natural inputs of nitrogen (e.g., organic 

decay) have always supplied very low levels of nitrate to the aquifer. However, anthropogenic sources (e.g., fertilizers and septic tanks) are increasing 

the input of nitrates into the system.

As expected, nitrate concentrations are low in most areas of the basin; 

in southwestern Hernando County, however, the leaching of nitrogen has 

increased nitrate concentrations in the aquifer. Recent water quality studies 

Water Quality Assessment Report: Springs Coast 49
indicate that 95 tons of nitrate per year are discharged from Weeki Wachee 

Springs. Also, the dramatic increase in nitrate concentrations in the spring 

since the early 1970s is most likely due to the increased human population 

in and near Spring Hill.

Recent studies show that the nitrate in the Floridan aquifer system 

originates from inorganic fertilizers applied to turf acreage near the four 

major spring complexes. However, the basin’s growing population will 

likely increase the signifi cance of organic sources of nitrogen, such as septic 

systems and wastewater treatment plants.

Major Water Quality Trends 

Nitrate Contamination in Spring Discharges

Nitrate concentrations have been increasing in a number of major 

spring groups in the SWFWMD, including Homosassa, Chassahowitzka, 

and Weeki Wachee Springs. The most dramatic increase in nitrate occurs 

in the Weeki Wachee main spring, where concentrations have increased 

from less than 0.02 milligrams per liter (mg/L) in 1946 to 0.88 mg/L 

in 2004.

Nitrate concentrations in ground water in undeveloped areas of Citrus, 

Hernando, and Pasco Counties were compared with nitrate concentrations 

in ground water discharging from the springs. The spring water concentrations exceeded natural background ground water concentrations. Because 

the enrichment of nitrate to the level occurring in the spring water does not 

result from natural processes, human-induced contamination of the ground 

water must be occurring somewhere within the recharge area of the springs.

Although the nitrate concentrations (0.18 to 0.88 mg/L) in the coastal 

springs of Citrus, Hernando, and Pasco Counties are considerably lower 

than those of springs in the surrounding basins, such as Lithia, Buckhorn, 

and Rainbow Springs, they are still of great concern. Even at these low 

concentrations, water discharging at the rate of approximately 900 cfs from 

the main springs and smaller, surrounding springs contains an annual 

nitrate load of over 360 tons. The coastal rivers rapidly deliver this nitrate 

to the estuaries along the Gulf Coast. As nitrate concentrations continue 

to rise, it is likely that algae blooms will increase in frequency and duration, and the vegetative composition of these estuarine aquatic systems will 

be altered.

The water discharging from the springs has probably not been in the 

aquifer for more than a few decades at most. Nitrogen isotopic data suggest that the dominant source of nitrate currently discharging from the 

springs is inorganic. Residential and golf course turf and landscape fertilizers are the likely sources. Organic sources, although regionally less signifi -

cant, may still elevate nitrate concentrations to high levels on a local scale. 

Organic sources include naturally occurring organic decay; sewage effl uent 

disposal; the land disposal of sewage sludge; effl uent from septic tanks; the 

land disposal of septage sludge; and poultry, dairy, and cattle operations.

50 Water Quality Assessment Report: Springs Coast
Watershed Management Activities and 

Processes

Over the years, management plans and activities in the basin have been 

implemented to eliminate wastewater discharges; reduce the discharges 

of polluted stormwater from urban and agricultural areas; and protect, 

preserve, and restore special areas. The following section describes historical, current, and ongoing activities and processes to address water 

 quality problems.

Much of the progress in the Springs Coast Basin in developing water 

quality restoration plans and implementing watershed and water quality 

improvements is attributable to coordinated local, state, and regional 

efforts. In particular, local organizations and initiatives have provided 

leadership in waterbody restoration and preservation efforts. Many plans 

share common goals, and their implementation is based on various groups 

playing critical roles in planning, funding, managing, and executing projects. The Department continues to coordinate its efforts with these entities 

to obtain data, improve monitoring activities, and exchange information 

through periodic meetings.

A number of major restoration initiatives, if continued, will have 

 signifi cant positive effects on the basin’s water quality.

Crystal River/Kings Bay Surface Water Improvement and 

Management Plan

As discussed earlier, the original Crystal River/Kings Bay SWIM Plan 

was prepared and approved in 1989, and the plan was updated in 2000. 

Many of the projects identifi ed in the original SWIM plan were for studies and data collection efforts—diagnostic tools for resource managers— 

designed to provide an insight into the intricacies of the system. An 

emphasis was placed on the development of a comprehensive understanding 

of the water chemistry of Kings Bay and Crystal River.

The results of this diagnostic work provided the necessary technical 

information to develop the management strategies for the 2000 SWIM 

plan update. Ongoing work on fi ve coastal rivers (including Crystal River) 

and their nutrient assimilative capacity may recommend expanding management actions farther down the rivers and perhaps to the nearshore gulf 

systems.

The Crystal River/Kings Bay SWIM Plan has established the following 

goals:

• Achieve and maintain water clarity that will provide an annual average horizontal Secchi depth reading of 45 feet,

• Stabilize or remove the sediment from areas that have been demonstrated to contribute to reduced water clarity as a result of sediment 

resuspension,

• Revegetate denuded areas with desirable submerged aquatic 

 vegetation, and

• Restore vital aquatic habitat.

Water Quality Assessment Report: Springs Coast 51
Proposed projects in the SWIM plan include the improvement of 

stormwater management systems for sediment and debris control, the 

removal of accumulated sediment from targeted areas of Kings Bay, 

revegetation following sediment removal, water quality monitoring, and 

the removal of accumulated Lyngbya sp. from targeted areas of Kings Bay. 

Lyngbya is a hairlike, fi lamentous alga that grows in large mats on the 

 surface and bottom of the bay.

Land Acquisition

Several agencies have land-buying programs in the basin. These 

include the Department’s Conservation and Recreation Lands Program, 

the SWFWMD’s Save Our Rivers (SOR) Program, and Preservation 

2000 and its successor, Florida Forever. The lands targeted for acquisition 

include riverine swamps and fl ood conveyance corridors, particularly those 

downstream of fl ood detention areas, those in areas of heavy development 

pressure, or those adjacent to other SWFWMD or public land holdings. 

Usually, these land acquisition programs emphasize the preservation of 

natural systems and the enhancement/preservation of water quality. However, because the lands purchased are often fl ood-prone wetland areas, the 

acquisitions also prevent development in historical fl ood storage areas.

A number of sites in the Springs Coast Basin have been formally 

evaluated by SOR and approved for acquisition. These include the Chassahowitzka Riverine Swamp Sanctuary, Weeki Wachee Preserve, Annutteliga 

Hammock, Starkey Wilderness Preserve, Pasco 1, and Hidden Lake Property. The acquisition of the Annutteliga Hammock and Pasco 1 projects is 

ongoing, while the purchase of the other projects has been completed.

In 1990, Penny for Pinellas was created. The principal goal of this 

one-cent local option sales tax was to make funds available for the county’s 

endangered lands program. In 1997, voters extended the tax for 10 years.

Nitrate Remediation Workgroup

The Springs Coast Comprehensive Watershed Management team initiated the Nitrate Remediation Workgroup to address impacts to the region’s 

springs and drinking water sources caused by increasing nitrate levels in 

ground water and surface water. The workgroup is composed of citizens, 

industry, and government representatives, including the SWFWMD.

In 2001, more than 2,900 surveys were mailed to residents in the 

Chassahowitzka, Homosassa, Kings Bay, and Weeki Wachee areas to help 

determine how homeowners in the area fertilize and water their lawns and 

gardens. The information gathered was used to develop an educational 

program on fertilization and irrigation practices for homeowners, in order 

to reduce water quality impacts to the basin’s springs and spring-fed rivers.

Pasco County Watershed Management Plan

The Anclote River Watershed Master Plan (Phase I) was completed in 

February 2001 by Camp Dresser & McKee Inc. for Pasco County under 

a cooperative project with the SWFWMD. Phase I includes the development of a stormwater model of the watershed and preparation of fl ood 

insurance maps. The next phase will address water quality and natural 

systems.

52 Water Quality Assessment Report: Springs Coast
Pinellas County Watershed Management Plan

In 1989, Pinellas County began a program of surface water management based on the watershed boundaries of its 52 watersheds. The 

watershed management planning initiatives that evolved from this were 

comprehensive in nature, including fl ood control, erosion control, conservation, water quality restoration and protection, natural systems conservation 

and restoration, and the protection of coastal water quality, biodiversity, and estuarine productivity. The county’s Stormwater Management 

Plan incorporates these aspects of water resource planning into a single 

 comprehensive plan.

Additionally, in 1993 the county developed a priority order for the 

development of individual plans for the 52 watersheds. By 1995, the 

county had completed basin studies for Belleair Creek, Bishop Creek, 

Mullet Creek, Allen’s Creek, and Lake Tarpon basin/watersheds. In 2001, 

the Lake Seminole Watershed Management Plan was completed; the plan 

provides a detailed restoration plan for the watershed and lake.

City of Clearwater

The city of Clearwater has completed two watershed management 

plans with water quality sections. The fi rst plan was completed in June 

1997 for the Alligator Creek watershed. The second was completed in 

August 2001 for the Stevenson’s Creek watershed. The city published a 

surface water quality monitoring report until 1995.

Agricultural Best Management Practices

The FWRA authorizes the Florida Department of Agriculture and 

Consumer Services (DACS) to develop interim measures and agricultural 

best management practices (BMPs). Additional authority for agricultural BMPs is provided in legislation on nitrates and ground water (Section 576.045, F.S.), the Lake Okeechobee Protection Program (Section 

373.4595, F.S.), Agricultural Water Conservation (Section 570.085, F.S.), 

and Florida Right to Farm Act Amendments (Section 823.14, F.S.). 

While BMPs are often adopted by rule, they are voluntary if not covered 

by regulatory programs. If they are adopted by rule and the Department 

verifi es their effectiveness, then implementation provides a presumption of 

 compliance with water quality standards.

Over the last several years, DACS has worked with agriculturists, soil 

and water conservation entities, the University of Florida’s Institute of Food 

and Agricultural Sciences, and other major interests to improve product 

marketability and operational effi ciency by implementing agricultural 

BMPs, while at the same time promoting water quality and water conservation objectives. In addition, programs have been established and are being 

developed to create a network of state, local, federal, and private sources of 

funds for developing and implementing BMPs.

Water Quality Assessment Report: Springs Coast 53
Manuals for Best Management Practices

To encourage growers to use BMPs, manuals have been published for 

a number of agricultural industries, including container-grown plants, 

blended fertilizer plants, agrichemical handling and farm equipment 

 maintenance, cow/calf operations, aquaculture, citrus, and landscaping. 

Many of these manuals can be downloaded at http://www.dep.state.fl .us/

water or http://www.fl oridaagwaterpolicy.com.

Manuals for row crops, equine or horse farms, and ornamental nurseries are currently being developed. The use of a BMP manual alone, 

however, does not afford a presumption of compliance with the Department’s water quality standards. In general, qualifying for a presumption of 

compliance requires that a site-specifi c BMP assessment process be in place 

or that practices being used have been proven effective through research 

and demonstration. 

54 Water Quality Assessment Report: Springs Coast
Chapter 3: Surface Water Quality Assessment

Scope of the Assessment

This chapter presents the results of an updated assessment of surface 

water quality in the Springs Coast Basin. The primary purpose of the 

assessment is to determine if waterbodies or waterbody segments are to be 

placed on the Verifi ed List of impaired waterbodies. The listing will be in 

accordance with evaluation thresholds and data suffi ciency and data quality 

requirements in the Identifi cation of Impaired Surface Waters Rule (IWR) 

(Rule 62-303, Florida Administrative Code [F.A.C.]). The results of the 

assessment will be used to identify waters in the basin for which total maximum daily loads (TMDLs) will be developed.

The chapter describes the planning units in the basin used as a basis 

for the assessment. A section on each planning unit contains a general 

description and summary of key water quality indicators (such as nutrients, chlorophyll a, dissolved oxygen [DO], and microbiological parameters). Permitted discharges, land uses, ecological status, and water quality 

improvement plans and projects are summarized for each planning unit. 

The discussion notes where applicable surface water quality criteria have 

been exceeded and summarizes the report’s fi ndings in maps, noting the 

impaired waterbodies in each planning unit. The chapter also contains 

background information on sources of data and on designated use attainment, and explains the state’s integrated water quality assessment process.

While impaired waters and their causative pollutants are identifi ed, it 

is not within the scope of this report to identify discrete sources of impairments. Information on the sources of impairment will be developed in 

subsequent phases of the watershed management cycle, including TMDL 

development and implementation.

Appendix A contains a discussion of the legislative and regulatory 

background for TMDL development and implementation. Appendix B 

contains supplementary information on the basin’s ecology. Appendix C

provides additional information on reasonable assurance. As part of the 

303(d) assessment of the Springs Coast Basin, the Florida Department of 

Environmental Protection (Department) received documentation from 

Pinellas County designed to provide reasonable assurance that proposed 

pollution control mechanisms would effectively address the nutrient-related 

impairment of Lake Seminole. While the fi nal agency action on this 

submittal will not occur until adoption of the Verifi ed List of impaired 

waters for the Group 5 basins, the Department has concluded that the Lake 

Seminole Reasonable Assurance Plan (plan) provides reasonable assurance 

that the lake will be restored. As such, the Department will approve the 

reasonable assurance proposal as part of the list adoption and will place 

Lake Seminole in assessment Category 4b. 

Water Quality Assessment Report: Springs Coast 55
In addition to providing detailed information about proposed pollution control mechanisms, including an implementation schedule, funding 

sources, and local commitments, the plan provides specifi c water quality 

targets that interpret the narrative nutrient criteria. The Department has 

concluded that the proposed control measures will achieve the water quality 

targets, which will implement the lake’s applicable water quality standards.

Appendix D provides the methodology used to develop the Planning 

and Verifi ed Lists. Appendix E lists the water quality monitoring stations 

used in the assessment. Appendix F lists, by planning unit, permitted 

wastewater treatment facilities in the basin that discharge to surface water 

and ground water (Table F.1), as well as Superfund sites and landfi lls 

(Tables F.2 and F.3, respectively); and Appendix G lists Level I land use 

by planning unit. The complete text of the IWR is available at http://

www.dep.state.fl .us/legal/Rules/shared/62-303/62-303.pdf.

Update on Strategic Monitoring and DataGathering Activities During Phase 2

During Phase 2 of the watershed management cycle, strategic monitoring and data-gathering activities focused fi rst on waters on the 1998 303(d) 

list, followed by waters that were placed on the Planning List through the 

IWR assessment alone. The majority of the strategic monitoring work 

was conducted by the Department’s Southwest District staff and included 

both chemical and biological monitoring and data upload to STOrage and 

RETrieval (STORET) databases. Data-gathering activities included working with environmental monitoring staff in the Southwest Florida Water 

Management District (SWFWMD) and local and county governments to 

obtain applicable monitoring data from their routine monitoring programs 

and special water quality projects in the basin.

Twenty-two waterbody segments on the Planning List and the 1998 

303(d) list needed further data to verify impairment. Parameters included 

DO, nutrients, coliforms, unionized ammonia, biological oxygen demand 

(BOD), total suspended solids (TSS), and mercury in fi sh.

Fifteen waterbody segments were verifi ed impaired for at least one 

parameter in the Springs Coast Basin as the result of strategic monitoring and data-gathering activities in Phase 2. Appendix E lists the water 

 quality monitoring stations used in the assessment.

Sources of Data

The assessment of water quality in the Springs Coast Basin includes an 

analysis of quantitative data from various sources, some of which are readily available to the public. These sources include the U.S. Environmental 

Protection Agency’s (EPA’s) Legacy and “new” STORET databases, the 

U.S. Geological Survey (USGS), and the Florida Department of Health 

(DOH). The STORET databases contain water quality data from a 

number of sources, including the Department, water management districts, 

56 Water Quality Assessment Report: Springs Coast
local governments, and volunteer monitoring groups. Appendix D

 contains a detailed description of STORET and the methodology used to 

develop the Planning and Verifi ed Lists, based on the IWR.

Table 3.1 summarizes the individual data providers who contributed to 

the IWR Database for the Springs Coast Basin for the period of record used 

in this assessment. Figure 3.1 contains a pie chart showing the amount of 

data provided by each source. Individual data providers who contributed 

to the IWR Database for the Springs Coast Basin during the period of 

record used in this assessment include the USGS, Department’s Southwest 

District, DOH, Florida Fish and Wildlife Conservation Commission, 

Pinellas County Department of Environmental Management, Hillsborough 

County, Florida LakeWatch, and SWFWMD.

In 2002, the Department created the IWR Database to evaluate data 

in accordance with the methodology prescribed in the IWR (Rule 62-303, 

F.A.C.). For the Planning List assessment, the data evaluation period 

of record is 10 years, and for the Verifi ed List, 7.5 years. Table D.2 in 

 Appendix D shows the periods of record for the Verifi ed and Planning Lists 

in the fi rst basin rotation cycle. Data collected between January 1, 1999, 

and June 30, 2006, were evaluated to establish the Verifi ed List for the 

Springs Coast Basin (IWR Run 29).

To support listing decisions, the evaluation of water quality in this 

basin also includes qualitative information drawn from data in technical 

reports and documents that are not yet included in the database. Some 

of these sources include historical water quality or ecological information 

that was not uploaded to the database because of its qualitative treatment 

of issues.

Attainment of Designated Use

While the designated uses of a given waterbody are established using 

the surface water quality classifi cation system described in Chapter 2, it is 

important to note that the EPA uses slightly different terminology in its 

description of designated uses. Because the Department is required to provide use attainment status for both the state’s 305(b) report and the state’s 

303(d) list of impaired waters, the Department uses EPA terminology when 

assessing waters for use attainment. The water quality evaluations and 

decision processes that are defi ned in Florida’s IWR for listing impaired 

waters are based on the following designated use attainment categories:

Aquatic Life Use Support-Based Attainment

Primary Contact and Recreation Attainment

Fish and Shellfi sh Consumption Attainment

Drinking Water Use Attainment

Protection of Human Health

Table 3.2 summarizes the designated uses assigned to Florida’s various 

surface water classes.

Integrated Report Categories and Assessment 

Overview

The EPA has requested that the states merge their reporting requirements under the Clean Water Act for Section 305(b) surface water quality 

reports and Section 303(d) lists of impaired waters into an Integrated Water 

Quality Monitoring and Assessment Report Guidance (Wayland, 2001). This 

Assessment Report integrates the 303(d) list and the 305(b) report for the 

Springs Coast Basin.

Following the EPA’s guidance, the Department delineated waterbodies or waterbody segments in each of the state’s river basins, assessed them 

for impairment based on individual parameters, and then placed them into 

one of fi ve major assessment categories and subcategories. These categories 

provide information on a waterbody’s status based on water quality, suffi ciency of data, and the need for TMDL development (Table 3.3). This 

Assessment Report contains a comprehensive evaluation of waterbodies that 

fall into Integrated Report Categories 1 through 5 in the table.

Not enough recent data on chemistry, biology, and fi sh consumption 

advisories have been collected; therefore, currently only a few water bodies 

or waterbody segments statewide fall into Category 1 (attaining all designated uses). In particular, fi sh tissues in many waterbodies statewide 

have not been tested for mercury. Out of 158 waterbodies or waterbody 

 segments in the Springs Coast Basin, none are in Category 1.

More waterbodies and segments statewide fall into Category 2 (attaining some uses but with insuffi cient data to assess completely) than Category 1 (attaining all uses), because monitoring programs can sometimes 

 provide suffi cient data for partially determining whether a designated use in 

a particular waterbody is attained. There are 23 waterbody segments in the 

basin which fall into Category 2.

Most waterbodies in the state, however, fall into Category 3 (having 

insuffi cient data). In the Springs Coast Basin, the breakdown of waterbodies or segments in Category 3 is as follows:

• Category 3a—49 segments for which no data are available to determine their water quality status,

• Category 3b—46 segments with some data but not suffi cient data for 

making any determinations, and

Understanding the 

Terms “Pollutant” 

and “Pollution”

For purposes of the TMDL 

Program, pollutants are 

chemical and biological 

constituents, introduced by 

humans into a waterbody, 

that may result in pollution 

(water quality impairment). 

There are other causes of 

pollution, such as the physical alteration of a waterbody 

(for example, canals, dams, 

and ditches). However, 

TMDLs are established only 

for impairments caused by 

pollutants (a TMDL quantifies 

how much of a given pollutant a waterbody can receive 

and still meet its designated 

uses).

Waterbodies that are verified impaired due to specified pollutants, and therefore 

require a TMDL, are listed 

under Category 5 in the Integrated Assessment Report; 

waterbodies with water 

quality impairments due to 

other causes, or unknown 

causes, are listed under Category 4c. Although TMDLs 

are not established for Category 4c waterbodies, these 

waterbodies still may be 

addressed through a watershed management program 

(for example, the Kissimmee 

River restoration).

Water Quality Assessment Report: Springs Coast 59
Table 3.3: Categories for Waterbodies or Waterbody Segments in the Integrated Report

Category Description Comments

1 Attaining all designated uses If use attainment is verified for a waterbody or segment that was previously listed as impaired, the Department will propose that it be delisted.

2 Attaining some designated uses 

and insufficient or no information 

or data are present to determine if 

remaining uses are attained

If attainment is verified for some designated uses of a waterbody or segment, the Department will propose partial delisting for the uses attained. 

Future monitoring will be recommended to determine if remaining uses 

are attained.

3a No data and information are 

 present to determine if any 

 designated use is attained

Future monitoring will be recommended to determine if designated uses 

are attained.

3b Some data and information are 

present but not enough to determine if any designated use is 

attained

Future monitoring will be recommended to gather sufficient information 

and data to determine if designated uses are attained.

3c Enough data and information are 

present to determine that one or 

more designated uses may not be 

attained according to the Planning 

List methodology

A waterbody or segment is potentially impaired for one or more 

 designated uses. These waters will be prioritized for future monitoring 

to verify use attainment or impaired status.

3d Enough data and information are 

present to determine that one or 

more designated uses are not attained according to the Verified 

List methodology

A waterbody or segment exceeds Verified List evaluation criteria and 

may be listed as impaired at the end of Phase 2 of the watershed management cycle. However, the data have not yet been fully evaluated and 

the waters have not been formally verified as impaired. Further monitoring and analysis may be necessary.

NOTE: This category is applicable only to the Status Report. Waters 

that pass the Verified List criteria at this stage of the process are placed 

in Category 5.

4a Impaired for one or more designated uses but does not require TMDL 

development because a TMDL has 

already been completed

After the EPA approves a TMDL for the impaired waterbody or segment, 

the TMDL will be included in a Basin Management Action Plan to reduce 

pollutant loading toward attainment of designated use(s).

4b Impaired for one or more designated uses but does not require TMDL 

development because the water 

will attain water quality standards 

due to existing or proposed 

measures

Pollutant control mechanisms designed to attain applicable water quality 

standards within a reasonable time frame are either proposed or in 

place.

4c Impaired for one or more designated uses but does not require TMDL 

development because impairment 

is not caused by a pollutant

This category includes waterbodies or segments that are impaired 

because of naturally occurring conditions or other causes of pollution. 

The impairment is not caused by specific pollutants. (See sidebar on 

previous page for a discussion of the difference between the terms 

 “pollutant” and “pollution.”)

5 One or more designated uses is 

not attained and a TMDL is 

required

Waterbodies or segments in this category are impaired for one or more 

designated uses by a pollutant or pollutants. Waters in this category are 

included on the basin-specific Verified List adopted by the Department’s 

Secretary as Florida’s impaired waters list and submitted to the EPA as 

Florida’s 303(d) list of impaired waters at the end of Phase 2.

Note: The descriptions in Table 3.3 are consistent with the EPA’s integrated assessment categories. In the Status Reports 

for Groups 1 through 3 and in the Assessment Reports for Groups 1 through 2 that were previously produced, Categories 

4b and 4c were reversed. That is, the description of Category 4b was previously listed as Category 4c, and the description 

of Category 4c was listed as Category 4b.

60 Water Quality Assessment Report: Springs Coast
• Category 3c—2 segments that are potentially impaired based on the 

Planning List criteria.

A number of waters either fail to meet water quality standards for DO 

or show signs of biological stress or nutrient impairment. According to the 

IWR, specifi c pollutants causing DO exceedances or biological stress, or 

an underlying nutrient imbalance creating an imbalance in fl ora or fauna, 

must be documented for a waterbody or segment to be listed as impaired. 

Sometimes these conditions cannot be linked to a causative pollutant, and 

sometimes they may refl ect natural background conditions.

Currently, 17 waterbodies in the basin are designated as being in 

Category 4. This category includes those waterbodies/segments that are 

impaired but do not require a TMDL for one of three reasons:

• Category 4a—No segments for which a TMDL has already been 

developed,

• Category 4b—1 segment for which there is reasonable assurance that 

the designated use of an impaired waterbody will be attained by an 

existing or proposed pollutant control measure, and

• Category 4c—17 segments for which the impairment is not attributable to a pollutant or pollutants, but is due to natural conditions or 

physical/hydrologic alterations to the waterbody.

Finally, 35 waterbodies in the basin are in Category 5. These impaired 

waterbodies are on the Verifi ed List of impaired waters adopted by the 

Department’s Secretary and will require TMDLs. Chapter 5 of this report 

discusses in detail the waters in this category.

Planning Units

The Springs Coast Basin encompasses approximately 800 square miles 

and a complex hydrologic system. To provide a more detailed geographic 

basis for identifying and assessing water quality improvement activities, the 

basin was subdivided into smaller areas called planning units. A planning unit is either an individual large tributary basin or a group of smaller 

adjacent tributary basins with similar characteristics. Planning units help 

organize information and management strategies around prominent watershed characteristics.

Water quality assessments were conducted for waterbody segments 

within planning units. Each of these smaller, hydrologically based drainage 

areas within a planning unit is assigned a unique waterbody identifi cation 

number (WBID). Waterbody segments are assessment units (or geographic 

information system polygons) that the Department used to defi ne waterbodies when it biennially inventoried and reported on water quality to the 

EPA under Section 305(b) of the federal Clean Water Act. These WBIDs 

are the assessment units identifi ed in the Department’s lists of impaired 

Water Quality Assessment Report: Springs Coast 61
waters submitted to the EPA in reports under Section 303(d) of the Clean 

Water Act.

The Springs Coast Basin contains fi ve planning units: Crystal River/

Kings Bay, Homosassa River, Chassahowitzka River, Middle Coastal, and 

Anclote River/Coastal Pinellas County. Table 3.4 describes these planning 

units, and Figure 3.2 shows their locations and boundaries. The remainder of this chapter provides a general description of each planning unit, 

information on land use and potential point sources of pollution, water 

quality assessments for individual waterbody segments, and summaries of 

ecological issues and watershed quality improvement plans and projects.

Appendix E of this report provides, by planning unit, a list of water 

quality monitoring stations, the integrated assessment (Master List) summary, and trend data. Appendix F includes summary information, by 

planning unit, for permitted wastewater treatment facilities, Superfund 

sites, and permitted landfi ll facilities. Appendix G lists Level I land uses, 

by planning unit. 

Assessment by Planning Unit

• Crystal River/Kings Bay Planning Unit

General Description

The Crystal River/Kings Bay Planning Unit covers about 78 square 

miles and contains 12 segments with WBIDs (Figure 3.3).

Crystal River and Kings Bay are located in Citrus County, approximately 60 miles north of Tampa. The tidally infl uenced Kings Bay is the 

headwaters of Crystal River, which forms at the northwest corner of the 

bay. The Kings Bay Springs Complex, the largest spring complex in the 

basin and the fourth largest in Florida, contains more than 30 springs; 

it discharges approximately 630 million gallons per day (mgd). Because 

of their regional signifi cance, both Crystal River and Kings Bay are 

 designated as Outstanding Florida Waters (OFWs) and Surface Water 

Improvement and Management (SWIM) priority waters.

The Crystal River Nuclear Power Plant lies along the coast, between 

the mouths of the Crystal and Withlacoochee Rivers.

Water Quality Summary

Historical water quality in the Crystal River/Kings Bay system was 

good. In recent years, however, nitrate contamination has increased. 

Because nitrate concentrations discharging from the springs are 20 times 

higher than the natural ground water concentrations in the Floridan 

aquifer statewide, much of the nitrate entering the system comes from the 

ground water discharging from the springs.

Water clarity in Kings Bay is primarily affected by the concentration 

of suspended solids in the water column. These result primarily from 

the resuspension of bottom sediments through wind action or physical 

 disturbance.

Hunters Spring Park, which is part of the Kings Bay system, was closed 

to swimming during most of the summer of 2000 due to elevated levels of 

total and fecal coliform bacteria.

The cooling-water intake pipes for the Crystal River Nuclear Power 

Plant extend into the nearshore area, causing localized increases in water 

temperature.

Figure 3.3, a composite map of the planning unit, shows waters on the 

1998 303(d) list and the Planning List. Table 3.5 summarizes the water

66 Water Quality Assessment Report: Springs Coast
Ecological Summary

While aquatic vegetation is important to water clarity in the Crystal 

River/Kings Bay system, undesirable aquatic vegetation has been a problem 

since hydrilla was introduced in 1960. Most recently, Lyngbya, an undesirable fi lamentous alga, has dominated areas of Kings Bay, causing habitat 

destruction, use impairment, and odor problems. Floating plants and 

 Eurasian milfoil (Myriophyllum spicatum) are problems in the Crystal River.

• Homosassa River Planning Unit

General Description

The Homosassa River Planning Unit covers about 90 square miles and 

contains 8 segments with WBIDs (Figure 3.4).

Like Crystal River, the Homosassa River is a coastal, spring-fed river/

estuarine system located in west Citrus County. Halls River is the only 

major tributary. The river, which has been designated as an OFW, extends 

approximately 6 miles from the Gulf of Mexico to its headwaters at Homosassa Springs. The springs discharge about 68 mgd.

Increased development pressures in the planning unit—including 

 residential and commercial growth in “Old Town” Homosassa and the

major types: domestic wastewater sources (which consist of 

sewage from homes, businesses, 

and institutions) and industrial

point sources. These sites have 

the potential to leach contaminants into ground water and

The National Priorities List 

(NPL) is a consolidated list of the 

uncontrolled hazardous waste 

sites that pose the greatest threat 

to public health or the environment. Sites are listed on the NPL 

upon the completion of a preliminary assessment, site inspection, 

and hazardous ranking system 

evaluation to determine their 

potential for adverse impacts and 

priority for corrective action. The 

EPA Superfund program administers the cleanup of NPL sites.

water in Florida. The Delineation 

Program is designed to ensure 

the protection of public health 

when consuming potable ground 

water supplies and to minimize 

the potential for cross-contamination of adjacent ground water 

resources.

The Delineation Program’s 

primary responsibilities are as 

follows:

• Delineate areas of ground 

water contamination,

• Implement a water well 

construction permitting/application process that requires 

stringent construction standards, and

• Require water testing after 

completion of the well to 

ensure the potable quality of 

the water source.

Any newly constructed water 

wells in delineated areas, and 

existing water wells found to be 

contaminated, are remediated by 

installing individual water treatment systems or by connecting 

the users to public water supply 

systems.

Nonpoint Sources and Land Uses

watershed, and into ground water 

supplies. Nonpoint sources also 

include atmospheric deposition 

and leaching from agricultural

bacteria, metals, sediments, and 

petroleum compounds.

Homosassa Springs area—have degraded the river’s water quality. The 

DOH and the Department found high concentrations of bacteria and 

nutrient enrichment. Nutrients increased from 1992 through late 1996 in 

the upper reaches of the river above Halls River. The Homosassa Springs 

State Wildlife Park, with assistance from the SWFWMD and the University of South Florida, investigated the potential addition of bacteria and 

nutrients from the park’s wildlife to the headwaters of the river. These 

impacts were relatively minor.

The predominant source of nutrients in the planning unit is golf 

course, residential turf, and landscape fertilizing. Septic tanks are also a 

signifi cant source.

Water Quality Summary

Historical water in the Homosassa River was good, and it remained 

good through the mid-1980s. A 1989 study, however, found signifi cant 

water quality degradation in the upper river, primarily due to the effects 

of septic tanks and treated wastewater effl uent. A salt wedge reaching 

upstream from the Gulf creates variations in salinity.

Figure 3.4, a composite map of the planning unit, shows waters on 

the 1998 303(d) list and the Verifi ed List. Table 3.6 summarizes the water

(approximately 48 percent of the planning unit’s area). Other major 

land uses include urban and built-up (22 percent) and upland forests 

(23 percent). These land uses can be associated with nonpoint discharges 

of pollutants and eroded sediments. Appendix G provides summary

• Chassahowitzka River Planning Unit

General Description

The Chassahowitzka River Planning Unit covers about 176 square 

miles and contains 8 segments with WBIDs (Figure 3.5).

The Chassahowitzka River is located in southwestern Citrus County 

approximately 6.5 miles south of Homosassa, just north of the Citrus– 

Hernando County line. The river begins at Chassahowitzka Springs, 

approximately 1.5 miles west of U.S. Highway 19 and just north of State 

Route 480. The springs discharge about 90 mgd.

From there, the river fl ows westerly to the Gulf of Mexico through 

about six miles of hardwood forests and low coastal marshland. Crab

Creek, Cabbage Creek, Baird Creek, Salt Creek, Potter Creek, Crawford 

Creek, Blue Run, Ryle Creek, and May Creek all fl ow directly to the Chassahowitzka River, while Chub Creek and Blind Creek fl ow to the Gulf of 

Mexico. The Chassahowitzka River and a number of creeks in the system 

are designated as OFWs.

Water Quality Summary

Water quality data for the Chassahowitzka River are limited. Limited 

historical data (collected before 1981) indicated that water quality was 

good. Data collected from 1992 through 1996 at selected springs are the 

most consistent data for this system. As with the other coastal spring 

systems in the basin, nitrates are increasing in the Chassahowitzka system, 

but mean nitrate concentrations were lowest in the Chassahowitzka 

Spring Complex.

Concerns about high bacteria levels in the Chassahowitzka River 

prompted the SWFWMD to perform remedial sampling of the headwaters 

and canals during the fall of 1997. Total and fecal coliforms were found to 

exceed state standards. A more detailed analysis, begun in October 1999, 

revealed that septic tanks are adversely infl uencing the water quality of 

the Chassahowitzka River. Fertilizing of golf courses, residential turf, and 

landscapes is also a signifi cant source of nutrients.

Figure 3.5, a composite map of the planning unit, shows waters on 

the 1998 303(d) list and the Verifi ed List. Table 3.7 summarizes the water 

quality assessment status of all waterbody segments in the planning unit.

• Middle Coastal Planning Unit

General Description

The Middle Coastal Planning Unit covers about 466 square miles and 

contains 53 segments with WBIDs (Figure 3.6).

The Weeki Wachee River is located in southwest Hernando County, 

about 12 miles southwest of Brooksville. Weeki Wachee Springs, the headwaters of the river and the largest of 9 springs associated with the Weeki 

Wachee system, lies just southwest of the junction of U.S. Highway 19 

and State Highway 50. The springs discharge an average of 176 cubic feet 

per second.

From its headwaters, the Weeki Wachee River extends westward 

through approximately 7.5 miles of coastal swamps and marshes to the 

Gulf of Mexico. The Department designated the Weeki Wachee River as 

an OFW.

Tributaries to the river include the Mud River and Jenkin’s Creek. The 

Mud River joins the Weeki Wachee about 0.8 miles upstream of the mouth 

of the river. The headwaters of Jenkin’s Creek are located east of County 

Road 595. The creek fl ows west-northwest approximately 1.3 miles 

through a coastal marsh before reaching the Gulf of Mexico less than a 

quarter-mile south of the mouth of the Weeki Wachee River.

Hammock Creek originates in several small springs clustered in a 

one-square-mile area in southwestern Hernando County. It is joined by 

several lesser tidal creeks before reaching the Gulf of Mexico at the town 

of Aripeka.

The Pithlachascotee (Cotee) River system, located in western Pasco 

County, includes both estuarine and freshwater reaches. The river extends 

approximately 25 miles in a southwest direction, from its headwaters at 

Crews Lake to the Gulf of Mexico at Port Richey.

Crews Lake, which covers approximately 693 acres, is directly connected to the Floridan aquifer by a sinkhole in the northern part of the 

lake. The lake level varies seasonally, and the lake may drain completely 

through the sinkhole during very dry years.

Water Quality Summary

Except for Weeki Wachee Springs, most of the springs in the Weeki 

Wachee area have very limited fl ow and water quality data. Changes 

in land uses in the watershed of the springs appear to have affected the 

coastal springs, rivers and creeks, and estuary. Although overall water 

quality in the river is still good, nitrate concentrations at the headspring 

have increased over time. In 1997, the mean nitrate concentration of the 

Weeki Wachee main spring was 0.53 milligrams per liter (mg/L) (for data 

collected from 1992 to 1996), 50 times higher than background levels 

(< 0.01 mg/L).

Water quality in the Hammock Creek system is relatively good, except 

for rising nitrate concentrations. This system experiences less infl ows of

fresh water than other river systems in the area, but remains an important 

part of the marine/estuarine ecosystem.

Crews Lake exhibited good water quality historically. The upper 

 portions of the Pithlachascotee River are surrounded by primarily rural 

land uses, while the lower reaches are relatively urbanized, especially 

around Port Richey and New Port Richey. This reach of the river receives 

signifi cant amounts of stormwater runoff. As a result, nitrogen and 

 phosphorus levels, as well as bacteria and protozoans, have increased.

Fertilizers on golf courses, residential turf, and landscapes are the predominant source of nutrients in the Weeki Wachee and Hammock Creek 

systems in the planning unit. Septic tanks are also a signifi cant source.

Figure 3.6, a composite map of the planning unit, shows waters on 

the 1998 303(d) list and the Verifi ed List. Table 3.8 summarizes the water 

quality assessment status of all waterbody segments in the planning unit.

Nonpoint Sources: Based on Levels I and II land use summary 

information, the predominant land use in the planning unit is urban 

and built-up (approximately 33 percent of the planning unit’s area). 

Other major land uses include upland forests (25 percent) and wetlands 

(22 percent). These land uses can be associated with nonpoint discharges

Notes:

1

The designation “stream” includes canals, rivers, and sloughs. The designation “lake” includes some marshes.

2The state’s surface water classifications are as follows:

Class I: Potable water supplies

Class II: Shellfish propagation or harvesting

Class III: Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife

Class IV: Agricultural water supplies

Class V: Navigation, utility, and industrial use (there are no state waters currently in this class) 3The EPA’s 305(b)/303(d) Integrated Report categories are as follows:

1—Attains all designated uses;

2—Attains some designated uses;

3a—No data and information are available to determine if any designated use is attained;

3b—Some data and information are available, but they are insufficient for determining if any designated use is attained;

3c—Meets Planning List criteria and is potentially impaired for one or more designated uses;

3d—Meets Verified List criteria and is potentially impaired for one or more designated uses;

4a—Impaired for one or more designated uses and the TMDL is complete;

4b—Impaired for one or more designated uses, but no TMDL is required because an existing or proposed pollutant 

control mechanism provides reasonable assurance that the water will attain standards in the future; 

4c—Impaired for one or more designated uses but no TMDL is required because the impairment is not caused by a 

pollutant; and

5—Water quality standards are not attained and a TMDL is required. 4The assessment categories listed in this column represent the status of each WBID as a whole, based on multiple parameters. 

The hierarchy of assigning these categories is Category 5, then 4, then 3c, then 2, and then 3b, i.e., each WBID is assigned a 

category based on the highest category assigned to an individual parameter. For example, if WBID 9999 has one parameter as 

a Category 5, then this supersedes parameters at Category 3c or 2, and the WBID as a whole is classed as a Category 5.

of pollutants and eroded sediments. Appendix G provides summary

Ecological Summary

Floating plants, cattails, and hydrilla are causing problems in the 

Weeki Wachee River.

Some wetlands in the planning unit, such as the Jay B. Starkey 

 Wilderness Park in Pasco County, have dried up as a result of ground 

water pumping from wellfi elds. In the early to mid-1980s, the SWFWMD 

 documented a shift from wetland to upland vegetation in the far 

 western portion of the planning unit, where the most pumping occurred 

before 1983.

• Anclote River/Coastal Pinellas County Planning Unit

General Description

The Anclote River/Coastal Pinellas County Planning Unit 

covers about 252 square miles and contains 91 segments with WBIDs 

(Figure 3.7).

The Anclote River, which originates in a swampy, low-lying area 

of south-central Pasco County, fl ows through the northwestern corner 

of Pinellas County and enters the Gulf of Mexico just north of Tarpon 

Springs. The principal tributaries to the river are Cross Cypress Branch, 

Sandy Branch, and South Branch. Near the coast are Salt Bayou, Whitcomb Bayou, and Kraemer Bay.

From its headwaters to the middle reaches, the river fl ows through 

pine fl atwoods, citrus, pasture, and forested wetlands. In most years, the 

upper portion of the river dries up periodically. The lower portion of the 

river is a tidal estuary that fl ows into Anclote Anchorage, a shallow area of 

seagrass beds to the east of Anclote Key. The lower stretches of the river 

fl ow through swampy tidally infl uenced lowlands, and tidal infl uences 

extend as much as 14 miles upstream. The mean depth of the lower river 

is just over 3 feet, except for a dredged shipping channel about 15 feet deep 

that extends from Tarpon Springs to the river mouth. Salinity at the river 

mouth ranges from 0.8 to 32.7 parts per thousand, depending on rainfall 

and tidal fl ows.

About 45 miles of barrier islands parallel the coast from the Anclote 

River to the mouth of Tampa Bay. Major land uses in the coastal region 

include residential and commercial development, citrus, and agriculture. 

From the Anclote River south to Sunderland Bayou, coastal communities 

such as mangroves and marshes predominate. Along the remainder of the 

coastline, however, the natural shoreline has been replaced with seawalls, 

fi lled beaches, and riprap.

The Boca Ciega Bay watershed comprises mostly urban land uses 

(83 percent). Boca Ciega Bay, the southernmost estuary in the basin, has 

been extensively modifi ed both physically and hydraulically. The bay, 

which covers about 181 square miles, has a mean depth of less than 7 feet. 

About 20 percent of its surface area was fi lled between 1950 and 1965. In 

addition, 5 major causeways cross the bay.

the 1998 303(d) List, Planning List and Verified List Waters, and Potential Pollution Sources

82 Water Quality Assessment Report: Springs Coast
Lake Seminole, the second largest lake in Pinellas County, was created 

in 1950 by damming the upper portion of Long Bayou. Currently, almost 

80 percent of the lake’s drainage area is urban. The lake was isolated by a 

water control structure built in the 1940s and now discharges over a weir to 

Long Bayou, which fl ows to Boca Ciega Bay.

Water Quality Summary

In the upper stretches of the Anclote River, low DO levels are common 

because of low fl ows and the presence of decomposing organic materials 

(leaves). Most of the land use in this area is agricultural, and the major 

water quality concerns are bacteria and nutrients. Salinity levels vary in the 

lower portions of the river because of tidal infl uences, and elevated levels of 

phosphorus occur periodically as a result of agricultural runoff. At Tarpon 

Springs, the river receives urban runoff and point source discharges. Tidal 

fl ows, rainfall, and runoff infl uence water quality in Anclote Anchorage. 

Urban land uses in the Anclote River watershed are expected to increase by 

over 270 percent by the year 2010, with corresponding losses to agriculture 

and upland forest of 98 and 71 percent, respectively.

Water quality in estuarine areas south of Anclote Anchorage depends 

on tidal fl ushing and the number of localized discharges from point and 

nonpoint sources. Curlew Creek has high levels of total phosphorus 

(TP), ammonia, total Kjeldahl nitrogen, and total and fecal coliforms. In 

St. Joseph Sound, north-to-south increases in color and chlorophyll a levels 

correspond with increased urbanization and point source discharges.

In the Clearwater Harbor watershed, land use mostly consists of highdensity residential development. Clearwater Harbor receives signifi cant 

amounts of drainage from creeks, channelized ditches and streams, storm 

sewers, and sheet fl ow. Water quality in the harbor is generally good; however, some tributaries and areas in the watershed have poor water quality, 

including Curlew Creek (high concentrations of nitrates and chlorophyll a) 

and Klosterman Bayou/Innisbrook Canal and Stevenson Creek (nitrogen, 

TP, TSS, and chlorophyll a). The Klosterman Bayou/Innisbrook Canal 

sampling station located at U.S. 19 was ranked worst among the sites in 

Clearwater Harbor sampled by Pinellas County.

The Narrows has poor water quality, with high levels of ammonia, TP, 

orthophosphate, and total Kjeldahl nitrogen from surface runoff and urban 

stormwater systems.

Water quality in Boca Ciega Bay is affected by proximity to the 

tributary mouths, barrier island passes, and seasonal patterns of water 

movement. A number of tributaries to the bay have been converted to 

underground storm sewers or open ditches, and generally, the quality of 

urban stormwater draining to the bay is poor. In some areas, there may 

also be sediment contamination. In particular, Cross Bayou, Long Bayou, 

Joe’s Creek, and Cross Bayou Canal are close to contaminated discharges, 

and fl ushing is restricted. These waterbodies have the worst water quality 

in the Boca Ciega Bay system, with low DO levels and high levels of nutrients, BOD, and coliform bacteria.

Stormwater from Bear Creek, a residential drainage basin, contains 

elevated levels of total and fecal coliforms, lead, and zinc, as well as the 

Water Quality Assessment Report: Springs Coast 83
 pesticides chlordane, Silvex, 2,4-D, and 2,4,5-T. Sediment samples from 

the creek contain high levels of volatile solids, total nitrogen, TP, and lead, 

in addition to chlordane, dichlorodiphenyldichloroethane, dieldrin, polychlorinated biphenyls, and heptachlor-epoxide.

The upper reaches of Joe’s Creek consist of two-thirds storm sewer and 

one-third open ditch. Stormwater and sediment quality in the creek are 

similar to those of Bear Creek, except for higher concentrations of heavy 

metals, lead, and zinc.

Lake Seminole, which has no tidal fl ushing, has had poor water quality 

for many years and is hypereutrophic. The lake has high concentrations of 

chlorophyll a and TSS. The blue-green alga Cylindrospermopsis sp. is the 

main contributor to the lake’s algal biomass.

Figure 3.7, a composite map of the planning unit, shows waters on 

the 1998 303(d) list and the Verifi ed List. Table 3.9 summarizes the 

water quality assessment status of all waterbody segments in the planning unit. The table and fi gure show that 36 waterbody segments in the

Notes:

1

The designation “stream” includes canals, rivers, and sloughs. The designation “lake” includes some marshes.

2The state’s surface water classifications are as follows:

Class I: Potable water supplies

Class II: Shellfish propagation or harvesting

Class III: Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife

Class IV: Agricultural water supplies

Class V: Navigation, utility, and industrial use (there are no state waters currently in this class) 3The EPA’s 305(b)/303(d) Integrated Report categories are as follows:

1—Attains all designated uses;

2—Attains some designated uses;

3a—No data and information are available to determine if any designated use is attained;

3b—Some data and information are available, but they are insufficient for determining if any designated use is attained;

3c—Meets Planning List criteria and is potentially impaired for one or more designated uses;

3d—Meets Verified List criteria and is potentially impaired for one or more designated uses;

4a—Impaired for one or more designated uses and the TMDL is complete;

4b—Impaired for one or more designated uses, but no TMDL is required because an existing or proposed pollutant 

control mechanism provides reasonable assurance that the water will attain standards in the future; 

4c—Impaired for one or more designated uses but no TMDL is required because the impairment is not caused by a 

pollutant; and

5—Water quality standards are not attained and a TMDL is required. 4The assessment categories listed in this column represent the status of each WBID as a whole, based on multiple parameters. 

The hierarchy of assigning these categories is Category 5, then 4, then 3c, then 2, and then 3b, i.e., each WBID is assigned a 

category based on the highest category assigned to an individual parameter. For example, if WBID 9999 has one parameter as 

a Category 5, then this supersedes parameters at Category 3c or 2, and the WBID as a whole is classed as a Category 5.

Permitted Discharges and Land Uses

Point Sources: Figure 3.7 shows permitted wastewater treatment 

facilities, landfi lls, and delineated ground water contamination areas in the 

planning unit. Appendix F lists the basin’s domestic and industrial surface 

discharge facilities, along with their permitted fl ows, by planning unit. It 

also lists landfi lls or solid waste facilities, by planning unit.

The Anclote River/Coastal Pinellas County Planning Unit contains 

76 permitted domestic and industrial facilities. Twenty-eight of them 

discharge greater than 0.1 mgd through surface water discharges or by land 

application of the effl uent.

There is one hazardous waste cleanup site in the planning unit.

The planning unit contains one closed and monitored Class I solid 

waste landfi ll; two closed and monitored Class III solid waste landfi lls; and 

one closed and monitored construction and demolition debris landfi ll. 

Nonpoint Sources: Based on Levels I and II land use summary 

information, the predominant land use in the planning unit is urban and 

built-up (approximately 57 percent of the planning unit’s area). Other 

major land uses include wetlands (14 percent) and agriculture (12 percent). 

These land uses can be associated with nonpoint discharges of pollutants 

and eroded sediments. Appendix G provides summary information on 

Level I land uses in the basin, by planning unit.

Ecological Summary

Invasive Exotic Species. In a number of areas in the Anclote River 

watershed, agricultural and urban development have provided pathways 

for invasive exotic species such as cogon grass (Imperata cylindrica); Brazilian pepper (Schinus terebinthifolius); air potato (Dioscorea bulbifera); skunk 

vine (Paederia foetida); melaleuca (Melaleuca quinquenervia), which is also 

called cajeput, or punk tree; and tropical soda apple (Solanum viarum). 

Portions of the SWFWMD’s Starkey wellfi eld property (about 8,000 acres) 

and the privately owned Anclote River Ranch (about 4,000 acres) have 

94 Water Quality Assessment Report: Springs Coast
problems with invasive exotics, as do urban areas near the mouth of the 

Anclote River.

In the western Pinellas peninsula, Brazilian pepper and Australian pine 

(Casuarina equisetifolia) are found along roadways and in disturbed coastal 

habitats (i.e., dredged and fi lled areas and residential areas). Pockets of 

Australian pine planted in the 1940s and 1950s can be found along several 

portions of the Intracoastal Waterway and the Gulf beaches. Infestations 

of hydrilla (Hydrilla verticillata) have been found in the Anclote River, 

Allens and Stevenson Creeks in the city of Clearwater, drainage canals and 

retention ponds in the city of Dunedin, and Lake Seminole. Other invasive 

species in the watershed include melaleuca and water hyacinth (Eichhornia 

crassipes).

Forest Fragmentation. Extensive land clearing for farming and cattle 

operations has resulted in the destruction and degradation of a number of 

ecosystem types in the Anclote River watershed, including pine fl atwoods, 

xeric habitats, and riparian and other wetland ecosystems. Urban development pressures are substantial near the mouth of the Anclote River and the 

southern boundary of the Anclote River watershed. The largest areas of 

remaining natural habitat include the SWFWMD’s Starkey wellfi eld property (about 8,000 acres), the Serenova tract (about 10,000 acres), and the 

privately owned Anclote River Ranch (about 4,000 acres). Ground water 

pumping at the Starkey wellfi eld has degraded wetland habitats both inside 

and outside the wellfi eld’s boundaries.

Habitat destruction and fragmentation in western Pinellas County 

have also been severe. Dredging and fi lling along the coast and on the 

barrier islands have destroyed tidal marsh and tidal swamp habitats, while 

inland development has eliminated most areas of pine fl atwoods, depression 

marsh, and xeric habitat. The remaining natural habitats are highly fragmented and subject to urban impacts. Some of the largest publicly owned 

lands include Caladesi and Honeymoon Islands, as well as lands owned by 

Pinellas County adjacent to Boca Ciega Bay (about 200 acres). Habitat 

improvement efforts in the watershed should focus on restoring coastal 

wetland and upland habitats.

Habitat Balance. About 1.9 percent of Pinellas County consists of 

conservation lands; Pasco County ranks higher, with 10.4 percent of its 

lands in conservation. Pinellas County is currently attempting to acquire 

land along the Anclote River corridor to provide a connection to the 

Brooker Creek Preserve, and possibly the Starkey Preservation Area in 

Pasco County. 

Critical issues in the Anclote River watershed include maintaining 

buffers and fl oodwater storage areas, as well as stream basefl ow. In western 

Pinellas County, major issues include protecting mangrove habitat; reducing motorized boat traffi c to protect nearshore and inshore areas from 

wake-generated wave damage, propeller dredging, and damage to seagrass 

from boat propellers; altering shoreline protection devices; restoring seagrasses and dredge holes in the bay bottom; and establishing (or reestablishing) tidal connections to increase water exchange.

Protection of Wildlife Corridors. Signifi cant areas of wildlife habitat remain in the Anclote River watershed, and the potential for wildlife 

Water Quality Assessment Report: Springs Coast 95
 corridors is signifi cant. Riparian habitat and associated uplands along the 

middle and upper reaches of the Anclote River, as well as Cross Cypress 

Branch and Sandy Branch to the north and south, respectively, provide 

excellent linkages between areas of core habitat. Much of this riparian 

habitat is within the SWFWMD’s Starkey property (about 8,000 acres) 

and Serenova tract (about 10,000 acres).

In western Pinellas County, there are few remaining areas of core 

habitat and, therefore, little corridor potential. Lands adjacent to and near 

Long Bayou and Lake Seminole provide the best opportunity to protect 

wildlife corridor habitat.

Identifi cation and Protection of Estuarine Aquatic Ecosystems. 

The Anclote River watershed is still relatively undeveloped, except for 

the extreme western portion near Lake Tarpon and the Gulf of Mexico. 

Expanding residential growth into southern Pasco County, however, could 

jeopardize water quality in the Anclote River. A decline in water quality could damage seagrass beds located south and west of the mouth of 

the river.

Western Pinellas County, which is highly urbanized, directly infl uences water quality in lower Tampa Bay, Boca Ciega Bay, Long Bayou, and 

Clearwater Harbor. Between 1988 and 1994, seagrass coverage in Boca 

Ciega Bay increased by 17 percent. Future restoration projects should focus 

on both stormwater treatment and habitat restoration. Completed SWIM 

restoration projects include Joe’s Creek and Boca Ciega Phase I. Future 

projects include Cross Bayou/Joe’s Creek and Boca Ciega Phase II. Water 

quality and seagrass coverage in Clearwater Harbor and the estuarine 

coastal areas north of Clearwater should be monitored regularly in order to 

assess the health of these systems.

Nonpoint Source Loading. Historically, agricultural land uses were 

the major contributors to nonpoint source pollution in the Anclote River 

watershed. Recently, as the population has grown in southern Pasco and 

northern Pinellas County, urban and suburban runoff have become a 

signifi cant issue. Small creeks and tributaries that empty into the Anclote 

River, as well as the Anclote River itself, receive stormwater runoff from 

all of these sources. The SWFWMD has purchased thousands of acres of 

natural habitat in the watershed, which should help to maintain surface 

water quality in the middle and upper reaches of the Anclote River and its 

tributaries.

In western Pinellas County, stormwater runoff from urban and suburban development affects water quality in several estuarine areas, including 

Clearwater Harbor, Long Bayou, and Boca Ciega Bay. Several current and 

planned SWIM habitat restoration and stormwater improvement projects 

should help fi lter runoff before it enters these sensitive areas.

96 Water Quality Assessment Report: Springs Coast
Chapter 4: Evaluation of Ground Water and 

Geologic Influences on Impaired Waterbodies

This chapter evaluates the potential infl uences of ground water and 

the natural geologic, soil, and/or ground water chemistry on surface water 

 quality in the Springs Coast Basin. In particular, it focuses on surface 

waters on the Planning or Verifi ed Lists. The chapter contains a general 

and by-planning-unit discussion and presentation of information. It also 

includes recommendations for an alternative listing status for waterbodies 

that exceed Impaired Surface Waters Rule listing thresholds due to natural 

conditions. The listing parameters receiving scrutiny include nutrients 

(nitrate+nitrite, ammonia, orthophosphate) and dissolved oxygen (DO). 

Geology, Soil, and Ground Water

Ground Water and Springs 

Ground water recharge in the Springs Coast Basin takes place predominantly along the Brooksville Ridge and, to a lesser degree, in the 

Gulf Coastal Plain. Some recharge also occurs in the Tsala Apopka Plain. 

Regional ground water fl ow moves generally from east to west, from 

the Tsala Apopka Plain and the Brooksville Ridge westward to springs 

discharging in Citrus, Hernando, and Pasco Counties, at the boundary 

between the Coastal Swamps and the Gulf Coastal Plain. This discharge 

boundary lies just west of U.S. 19 within these counties and nearly coincides with the freshwater-saltwater transition zone.

As discussed in Chapter 2, the Springs Coast Basin contains 4 major 

spring complexes and numerous smaller springs, which occur as a result 

of the region’s karst geology. Combined, these 4 complexes discharge 

approximately 900 million gallons per day (mgd) from the Floridan aquifer 

system. Rainfall, the primary recharge mechanism for the aquifer, averages 

56 inches per year in the basin.

Spring fl ow is the major discharge mechanism for the aquifer, accounting for 64 to 84 percent of the total recharge input. The Crystal River/

Kings Bay Springs Complex, the largest such complex in the basin, 

 discharges approximately 630 mgd. The three other major springs—Weeki 

Wachee, Chassahowitzka, and Homosassa—discharge on average 113, 90, 

and 68 mgd, respectively. Other large springs in the basin include Ruth 

Spring, Salt Spring, Little Springs, Bobhill Springs, Magnolia Springs, 

Horseshoe Spring, Salt Springs, Wall Springs, Crystal Beach Submarine 

Spring (which is located about 1,000 feet offshore), and Tarpon Springs 

(which is tidally infl uenced and can reverse fl ow).

Water Quality Assessment Report: Springs Coast 97
In Pinellas County, the Coastal Swamps give way to barrier island 

complexes. Still, several smaller springs are present in the northern portion 

of the county. Due to a smaller upland recharge area and thickening 

coastal sediment cover, springs are absent within the confi nes of the Springs 

Coast Basin south of Clearwater.

For a more detailed discussion of Springs Coast hydrogeology, please 

refer to the Status Report for the Springs Coast Basin (Florida Department of Environmental Protection [Department], 2006) or other reports 

 referenced in this section.

Nutrients 

Nutrients in low concentrations, such as the various nitrogen species 

(nitrate, nitrite, nitrogen, ammonia) and phosphorus (usually as orthophosphate), are naturally occurring constituents of Floridan aquifer system 

ground water at low concentrations. Historical median background levels 

of nitrate+nitrite in the Floridan aquifer system are believed to both be on 

the order of 0.01 milligrams per liter (mg/L). (These nitrate+nitrite levels 

are measured as N and often collectively referred to as nitrate, because 

nitrate always predominates over nitrite in concentration.) Orthophosphate 

concentrations, also naturally low and on the same order as nitrate, can be 

higher in noncarbonate aquifers, such as the surfi cial aquifer system.

Nutrients, in particular the various nitrogen species, are the predominant analytes of concern for potential ground water contamination 

of surface waterbodies in the basin. Nitrogen occurs naturally in both 

organic and inorganic forms, but elevated detections of inorganic nitrogen 

in ground water are typically associated with pollutant sources. Isotopic 

studies of nitrate in the Homosassa, Chassahowitzka, Weeki Wachee, and 

Aripeka Spring Complexes have determined that the nitrate in ground 

water is from primarily inorganic sources (Jones, Upchurch, Champion, 

and DeWitt, 1997). Inorganic nitrogen is typically associated with fertilizer that is applied in agricultural areas, on turf, and on residential lawns.

Nutrients, especially nitrate, are the pollutants of greatest concern in 

ground water discharge to surface waters in the basin. Changing land uses 

in the ground water recharge areas of the basin since the 1970s coincide 

with a dramatic increase in nitrate concentrations, while phosphorus levels 

have remained relatively steady. This is because nitrate is relatively nonreactive within the Floridan aquifer system, while orthophosphate is reactive. 

Most nitrogen species introduced into the aquifer convert to the nitrate 

anion (NO3-) and pass through from source to discharge point, with concentrations only signifi cantly diminished by dilution from aquifer waters 

containing lower nitrate concentrations. For orthophosphate, however, 

the geochemistry of the Floridan aquifer system’s carbonate matrix favors 

the reaction between ground water orthophosphate (PO4-3) and calcite 

(CaCO3), the predominant mineral in limestone. This reaction forms 

phosphorite, a rock composed predominantly of carbonate-hydroxylapatite 

(Ca5[OH,O|(PO4,CO3)3]).

Orthophosphate levels can be higher in noncarbonate aquifers, such 

as the surfi cial aquifer system, depending on the chemical composition of the aquifer material. The Hawthorn Group, which serves as an 

98 Water Quality Assessment Report: Springs Coast
upper confi ning unit for the Floridan aquifer, includes natural deposits of 

 phosphate and is a source of phosphorus in some ground waters. 

Elevated nutrient levels in surface waters can cause excessive chlorophyll growth (measured as high chlorophyll a levels in streams and 

estuaries) and high Trophic State Index (TSI) values (measured in lakes). 

Another adverse effect of elevated nutrients is the excessive growth of algae 

and invasive plants, which can result in ecological imbalances in spring-run 

systems and their receiving waters. These types of ecological imbalances 

constitute the predominant impacts to the majority of springs in Florida, 

including those in the Springs Coast Basin, and can be the result of relatively small increases in nitrate or phosphorus.

Recent research by Stevenson, Pinowska, Albertin, and Sickman 

(2007) suggests that reductions in total nitrogen to levels substantially 

below 0.25 mg/L and total phosphorus to levels below 0.026 mg/L are 

needed to signifi cantly reduce the extent of spring bottom cover of the 

algal species Vaucheria sp. and Lyngbya wollei. (Most total phosphorus 

levels in ground water and basin springs are already below that value.) It 

is thought that nitrogen was the predevelopment limiting nutrient in high 

ground water-sourced surface waters, but that due to the recent increases in 

nitrate concentrations in ground water, phosphorus has become the limiting 

nutrient, much of it entrained in and recycled from geologic material and 

stream-bottom sediments.

Dissolved Oxygen

Low DO levels are characteristic of ground waters with long underground residence times (such as most Floridan aquifer system waters). 

Ground water-sourced rivers, such as the spring-fed coastal rivers in the 

Springs Coast Basin, show initially low DO values when measured at the 

head springs. In these rivers, which have substantial submerged aquatic 

vegetation in their upper reaches, low DO values can rebound to normal 

levels within a relatively short distance downstream from the head spring, 

because plant photosynthesis releases DO into the water column. Spring 

runs with little submerged aquatic vegetation have lower DO values that 

can negatively affect the diversity and abundance of fi sh and invertebrate 

species. DO levels can also be depressed in surface water systems because 

of nutrient enrichment and/or biochemical oxygen demand (BOD). In 

addition, low DO can be attributed to poor water circulation caused by 

stream channelization or disruption in fl ow. 

Evaluations by Planning Unit

This section summarizes, for each planning unit, ground water chemical characteristics that may be related to impaired waterbodies on the 

Verifi ed List, evaluates ground water fl ow, reviews pertinent geologic and 

soil information, and evaluates land use and anthropogenic sources. The 

discussion focuses on ground water sources affecting surface waters and is 

thus oriented more toward major spring discharge locations in each planning unit and their associated springsheds, in deference to planning unit 

boundaries.

Water Quality Assessment Report: Springs Coast 99
Overview of Ground Water and Spring Water Quality 

Tables 4.1 and 4.2 present water quality statistics from wells and 

springs for all of the basin’s planning units. The data were obtained 

from the Department’s Oracle-based Ground Water Information System 

(OGWIS) and from the Southwest Florida Water Management District 

(SWFWMD) Water Quality Monitoring Program. Data retrieved from 

OGWIS were for the Floridan and surfi cial aquifer systems and springs. 

SWFWMD data were obtained for the upper Floridan aquifer and springs.

100 Water Quality Assessment Report: Springs Coast
Median ground water values for 3 of the 5 planning units indicate that 

nitrate+nitrite (dissolved, measured as N) in ground water was elevated 

compared with historical background levels for both the surfi cial and 

Floridan aquifer systems, but was well below the Florida primary ground 

water standard of 10 mg/L. Median values for nitrate+nitrite from springs 

were highest in the Anclote River Planning Unit, at 6.0 mg/L (data from 

5 springs), and lowest in the Crystal River/Kings Bay Planning Unit at 

0.2 mg/L (data from 23 springs). 

Ammonia (dissolved, measured as N) values from Floridan aquifer 

system wells and springs are typically very low, except in cases where 

very localized sources are present. These sources are usually organic and 

include concentrated animal-feeding operations or malfunctioning septic 

or sewage systems. Ammonia typically converts to nitrate before it reaches 

the aquifer.

Orthophosphate (dissolved, measured as P) ground water values for 

all fi ve planning units are at or near historical background concentrations, except for surfi cial aquifer system values in the Middle Coastal 

Planning Unit; however, this was based on samples from only two wells. 

Springs values were also near historical background concentrations, except 

for a median value of 0.07 mg/L from two springs in the Anclote River 

 Planning Unit.

DO values from both surfi cial and Floridan aquifer system wells were 

suboptimal by surface water standards but relatively normal for ground 

water, with surfi cial values generally higher than Floridan values, as 

expected, because ground water residence times in the surfi cial are generally 

shorter than in the Floridan.

Figures 4.1 and 4.2 depict the value ranges and sample locations for 

nitrate+nitrite and orthophosphate, respectively, for springs and wells in the 

Springs Coast Basin. Also shown are the locations of major springsheds 

for the larger Springs Coast spring groups. Springsheds are ground water 

capture areas that contribute water to springs, like a surface watershed. 

Note that springshed boundaries include large recharge areas that extend 

beyond the Springs Coast Basin, which was defi ned using surface water 

basins. The fi gures clearly show that ground water from recharge areas 

along the Brooksville Ridge outside the Springs Coast Basin (and Tsala 

Apopka Lake for the Kings Bay and Homosassa springsheds), but within 

the adjacent Withlacoochee Basin, fl ows west to discharge at points along 

the Springs Coast.

Crystal River/Kings Bay Planning Unit 

While no surface waters in the planning unit are currently listed as 

impaired for nutrients or DO, there are serious ecological imbalances in 

Kings Bay and Crystal River associated with nutrients from springs. The 

Kings Bay Springs Group is the second largest spring system in Florida by 

volume of water discharged and includes 30 known springs (Champion, 

2001). The springshed for this group is expansive, including the eastern half of the Crystal River/Kings Bay Planning Unit, the northeastern 

half of the adjacent Homosassa River Planning Unit, and a large region

north, northeast, and east of these planning units extending into the 

 Withlacoochee Basin.

The median nitrate+nitrite value from 51 Floridan aquifer system wells 

in the planning unit was 0.10 mg/L, higher than historical statewide background concentrations of about 0.01 mg/L. Historical water quality data 

from Kings Bay springs are few, but they do show that nitrate concentrations in the early 1900s were 20 times lower than they are now (Upchurch, 

1992). Table 4.2 indicates that the median value for nitrate+nitrite 

for 23 spring stations in the Crystal River Planning Unit is 0.20 mg/L, 

 elevated compared with background but lower than spring median values 

in any of the other Springs Coast Basin planning units. Hunter Spring, 

one of the major springs in the group, has nitrate at concentrations signifi -

cantly higher than this median. 

Figure 4.3 shows recent nutrient concentrations in Hunter Spring and 

the other major spring in this group, Tarpon Hole (both sampled quarterly 

since October 2001 by the Department’s Florida Springs Initiative). Over 

this period, nitrate+nitrite values are elevated, but no major trends are 

discernible. Prior to this time, a slight upward trend in nitrate concentrations (increasing from around 0.25 to 0.35 mg/L from 1991 to 1998) had 

been measured at Hunter Spring (Jones, Upchurch, and Champion, 1998). 

The results from this study for Tarpon Hole Spring are similar to those 

shown in Figure 4.3, indicating that no signifi cant increases in nitrate

have occurred since 1991 and that the average concentrations are much 

lower than those from Hunter Spring. The dissimilarity between nitrate 

trends and concentrations for Hunter Spring and Tarpon Hole Spring is an 

example of how different sources can affect individual springs in the Kings 

Bay springshed. Also shown in Figure 4.3 are the relatively low orthophosphate concentrations, which display no trends and are similar to most major 

springs in the state.

Several researchers have noted the increasing occurrence of Hydrilla sp.

and the alga Lyngbya wollei, along with a decline in native submerged 

aquatic vegetative species. In a SWFWMD study of these invasive species, 

Romie (1990) determined that ground water discharge from springs was 

responsible for 94 percent of the total nitrogen and 84 percent of the total 

phosphorus entering Kings Bay. Other sources noted in this study included 

stormwater runoff, septic tank leachate, package plant effl uent, and the city 

of Crystal River’s sewage treatment plant discharge into Cedar Cove (part 

of Kings Bay). The Crystal River sewage treatment plant ceased discharging treated effl uent into Cedar Cove in 1992 (SWFWMD, 2004). Tidal 

fl uctuations also affect loading, particularly from springs whose fl ow is 

affected by the interrelationship between sea level and aquifer head. 

A SWFWMD study of the Kings Bay springshed by Jones, Upchurch, 

and Champion (1998) stated that low sulfate concentrations and isotopic 

data indicate a shallow ground water fl ow regime in the Floridan aquifer 

system, and that waters discharging from area springs generally come from 

aquifer recharge that occurred during the last 50 years. The study indicated that the widespread use of inorganic fertilizers on residential lawns 

and golf courses was principally responsible for nitrate to ground water, 

and that nitrate contributions may increase along with development in 

the Crystal River area and outlying springshed. Ground water enriched 

in nitrate from development-related and natural sources was noted in 

well- defi ned plumes from northern and east-central Citrus County; these 

plumes were predicted to reach the Kings Bay Springs Group by about 

2010, causing an increase in nitrate discharging from these springs. Data 

specifi cally indicated anomalously high local recharge in Beverly Hills, a 

highly developed residential area atop the Brooksville Ridge within the 

springshed, approximately 8 miles east-northeast of Kings Bay.

Ammonia in ground water is low (a median value of 0.08 mg/L 

from 5 Floridan aquifer system wells) in ground water of the Kings Bay 

springshed. A median value of 0.01 mg/L from 11 sampled springs refl ects 

background conditions for this analyte.

DO values from 5 Floridan aquifer system wells in the planning unit 

had a median value of 0.43 mg/L, low for surface waterbodies but within 

the normal range for Floridan ground water. DO was not identifi ed as an 

impairment for springs and spring-dominated streams in the planning unit 

because of the ground water contribution.

Homosassa River Planning Unit 

No surface waters in the planning unit are currently listed as impaired 

by nutrients or DO; however, ecological imbalances in the Homosassa 

River (algal blooms and accumulation) do exist, likely related to nutrients 

Water Quality Assessment Report: Springs Coast 105
from springs. The springshed for the Homosassa Springs Group encompasses the south-central portion of the Homosassa River Planning Unit, 

the northeastern half of the adjacent Chassahowitzka Planning Unit, and 

a large region east of these planning units that extends into the Withlacoochee Basin.

The median nitrate+nitrite value from 25 Floridan aquifer system wells 

in the planning unit was 0.22 mg/L, somewhat higher than background. 

Historical water quality data from the Homosassa Springs Group are 

limited: nitrate concentrations in 1946 and 1956 were 0.2 and 0.13 mg/L, 

respectively, and were at a similar level in the 1970s (ranging from 0.2 to 

0.3 mg/L). In the latter half of the 1990s, nitrate concentrations in the 

Homosassa Springs Group had risen to approximately 0.4 to 0.5 mg/L. By 

2001, they were in the 0.5 to 0.6 mg/L range, a signifi cant increase since 

the 1970s. For the 30 spring stations in the planning unit, the median 

nitrate concentration is 0.45 mg/L (Table 4.2).

Figure 4.4 shows recent nutrient concentrations in the three springs 

that make up the source of the Homosassa River. The similarity in nitrate 

trends and concentrations indicates that all three vents respond in a similar 

manner for this analyte and that all three likely receive signifi cant recharge 

from the larger springshed, which includes portions of the Brooksville 

Ridge and Lake Tsala Apopka in the Withlacoochee Basin. Other analytes sampled from these vents, however, show differences in water quality,

 indicating potentially different local recharge sources (Champion and 

Starks, 2001).

The SWFWMD springs study that included Homosassa (Jones, 

Upchurch, Champion, and DeWitt, 1997) stated that low sulfate concentrations and isotopic data indicate a short, shallow ground water fl ow 

regime in the Floridan aquifer system, and that water discharging from the 

springs is generally less than 50 years old. The study investigated 14 potential nitrate sources in the springshed and concluded that residential and golf 

course turf/landscape fertilization were the principal sources of nitrate in 

Homosassa and other spring complexes to the south. The conclusions were 

based on the following: (1) the inorganic nature of the sources, as determined from nitrogen isotopic analyses; (2) the close proximity of sources to 

springs; and (3) the rapid increase in nitrate concentrations in the springs 

that began in the late 1960s, correlating with the development of the large, 

coastal residential subdivisions that contain the largest densities of residential and golf course turf and landscape.

The ammonia median value of 0.02 mg/L from 3 Floridan aquifer 

system wells in the planning unit and the median value of 0.01 mg/L 

from 10 springs in the planning unit are very low and refl ect background 

 conditions.

Orthophosphate in ground water is somewhat elevated (median of 

0.21 mg/L for 26 wells) compared with data from spring stations in the 

planning unit (median of 0.02 mg/L in 27 spring stations (Table 4.2). 

The ground water value is somewhat higher than the statewide background concentration for Floridan aquifer system ground water and may 

refl ect infl uence by phosphatic material in the overlying Hawthorn Group. 

The spring data also match well with data shown in Figure 4.4, which 

depicts similar concentrations and no trends from the 3 main Homosassa 

Spring vents. 

The DO median value for Floridan aquifer system wells in the planning unit was 0.62 mg/L, low for surface waterbodies but within the 

normal range for Floridan aquifer system ground water. Springs were not 

listed as impaired by low DO for this reason.

Chassahowitzka Planning Unit 

No surface waters in the planning unit are currently listed as impaired 

by nutrients or DO; however, similar nutrient-related ecological imbalances 

that were present in the other Springs Coast spring systems are present 

in the Chassahowitzka system. The springshed for the Chassahowitzka 

Springs Group roughly encompasses the southern half of the Chassahowitzka Planning Unit, the northeastern portion of the adjacent Middle Coastal 

Planning Unit, and a region southeast of these planning units along the 

Brooksville Ridge, extending into the Withlacoochee Basin.

The median nitrate+nitrite concentration for the 30 Floridan aquifer 

system wells in the planning unit was 0.28 mg/L. Nitrate+nitrite data from 

1 surfi cial aquifer system well in the planning unit was also 0.28 mg/L. 

Historical water quality data from the Chassahowitzka Springs Group is 

limited; measurements collected in 1946 showed nitrate concentrations 

near 0.05 mg/L. Nitrate data collected in the 1970s showed an increase, 

Water Quality Assessment Report: Springs Coast 107
generally within the 0.1 to 0.3 mg/L range. In the latter half of the 1990s, 

Chassahowitzka values had risen into the 0.4 to 0.5 mg/L range, and the 

trend since 2001 shows nitrate continuing to rise into the 0.6 mg/L range, 

a twelvefold increase since the mid-20th century and over 60 times more 

than historical statewide background Floridan aquifer concentrations 

(Champion and Starks, 2001). The median nitrate+nitrite concentration (from 36 spring stations) was 0.37 mg/L (Table 4.2). Figure 4.5

shows recent nutrient concentrations for the 2 main spring vents that are 

the source for the Chassahowitzka River. Nitrate concentrations in these 

2 springs are signifi cantly higher than the median for all springs in the 

group and provide the highest nitrate loads to the river.

The SWFWMD study (Jones, Upchurch, Champion, and DeWitt, 

1997) showed that water in the Chassahowitzka spring system is on average 

50 years old or younger. The study also showed that residential and golf 

course turf/landscape fertilization were the principal sources of nitrate in 

Chassahowitzka and other spring complexes to the north and south.

Another factor potentially affecting Chassahowitzka ground water 

quality is the absence of Hawthorn Group clays overlying Tertiary limestones along the Brooksville Ridge from the city of Brooksville north to 

the vicinity of the Citrus–Hernando County line. This area, which lies 

within the Chassahowitzka springshed, is home to numerous limestone 

 quarries excavated into the Suwannee Limestone, which covers many

square miles. These quarries act as penetrating karst features, which, along 

with numerous natural karst features in the Brooksville urban area, increase 

potential recharge directly into the Floridan aquifer system from the region, 

without signifi cant attenuation by overlying soils.

The ammonia median value of 0.04 mg/L from 4 Floridan aquifer 

system wells in the planning unit (at least 2 fall outside the Chassahowitzka 

springshed) and the median value of 0.01 mg/L from 13 spring stations in 

the planning unit are very low and refl ect background conditions.

Orthophosphate values for 26 spring stations in the Chassahowitzka 

Planning Unit had a median concentration of 0.02 mg/L (Table 4.2), and 

31 Floridan aquifer system wells in the planning unit (at least 2 are located 

outside the Chassahowitzka springshed) had a median value of 0.028 mg/L. 

These values are slightly higher than the statewide background concentration for Floridan aquifer system ground water. This also matches well with 

data shown in Figure 4.5, which depicts similar concentrations and no 

trends from recent data collected from the 2 main Chassahowitzka Spring 

vents. One surfi cial aquifer system well had an orthophosphate value of 

0.058 mg/L.

The DO median value for 4 Floridan aquifer system wells in the planning unit was 2.9 mg/L, somewhat elevated compared with other Floridan 

well samples in the basin. One surfi cial aquifer system well in the planning 

unit had a measured DO level of 4.97 mg/L.

Middle Coastal Planning Unit

No surface waters in the planning unit are currently listed as impaired 

by nutrients or DO; however, similar nutrient-related ecological imbalances 

that were present in the other Springs Coast spring systems are present 

in the Weeki Wachee Springs and Aripeka Springs Group— particularly 

Weeki Wachee, which has the highest nitrate concentrations. The 

springsheds for Weeki Wachee Springs and the Aripeka Springs Group 

(Bob Hill, Boat, Magnolia, and Aripeka Springs Nos. 1 and 2) encompass 

approximately the central third of the Middle Coastal Planning Unit. Part 

of the Weeki Wachee springshed extends into the adjacent Withlacoochee 

and Tampa Bay Tributaries Basins along and east of the Brooksville Ridge. 

The median nitrate+nitrite concentration for 83 Floridan aquifer 

system wells in the planning unit is 0.13 mg/L, similar to the northern 

planning units in the basin. Historical water quality data for Weeki 

Wachee Springs are limited and practically nonexistent for the Aripeka 

Springs Group. Figure 4.6 shows existing nitrate data for Weeki Wachee 

Springs from 1946 through 1999, compared with population trends in 

 Hernando County for the same period. The median nitrate+nitrite concentration for 28 spring stations in the basin is 0.44 mg/L (Table 4.2). Of 

these, Weeki Wachee Spring has the highest nitrate levels. 

More recent quarterly water quality data collected by the Department’s 

Florida Springs Initiative monitoring network indicate that nitrate+nitrite 

values in Weeki Wachee Spring have increased to a median concentration of 

over 0.8 mg/L, the highest of any major spring in the Springs Coast Basin. 

Because data from wells distributed throughout the planning unit show 

Water Quality Assessment Report: Springs Coast 109
very low nitrate+nitrite concentrations, it is likely that nutrient sources in 

the springs’s immediate area contribute the bulk of the nitrate load.

This is in agreement with conclusions reached by Jones, Upchurch, 

Champion, and DeWitt (1997). Their study concluded that, based on the 

above data and also on nitrogen isotope data, inorganic sources—principally residential and golf course turf/landscape fertilization—were the principal sources of increasing nitrate. These data and conclusions correlate 

with the development of the large, coastal residential subdivisions adjacent 

to Weeki Wachee, which contain the highest density of residential development and the largest number of golf courses (Figure 4.7).

 The ammonia median value of 0.04 mg/L from 19 Floridan aquifer 

system wells in the planning unit and the median value of 0.01 mg/L from 

11 springs in the planning unit are low and refl ect background conditions.

The 27 spring stations in the Middle Coastal Planning Unit had a 

median orthophosphate concentration of 0.01 mg/L (Table 4.2), which is 

essentially the same as background. Eighty-four Floridan aquifer system 

wells had a median orthophosphate value of 0.05 mg/L; these values are 

slightly higher than the statewide background concentration for Floridan 

aquifer system ground water. Two surfi cial aquifer system wells produced a

median orthophosphate value of 0.13 mg/L, which may be from the phosphorus in the Hawthorn Group material.

The DO median value for 19 Floridan aquifer system wells in the planning unit is 0.36 mg/L, low for surface waterbodies but within the normal 

range for Floridan ground water. A median DO value of 3.7 mg/L from 

2 surfi cial aquifer system wells is within the expected normal range for an 

unconfi ned shallow aquifer. Low DO in springs of this area is also typical 

and a natural occurrence.

Anclote River/Coastal Pinellas County Planning Unit 

Several waterbodies in the planning unit are listed as impaired by 

nutrients and/or low DO (14 for chlorophyll a or historical chlorophyll and 

9 for DO). The largest ground water contribution to these waterbodies is 

likely from the surfi cial aquifer via seepage, rather than from the Floridan 

aquifer via springs. Unlike the planning units to the north, the Anclote 

River/Coastal Pinellas County Planning Unit has few known springs, and 

the ones present are of low magnitude—this includes Tarpon, Health, and 

Water Quality Assessment Report: Springs Coast 111
Crystal Beach Submarine Springs. All of these springs are located in the 

northwest third of the planning unit.

The subsurface geology of most of the planning unit differs from that 

to the north. The northern coastal Pinellas and western Anclote River 

watersheds occupy an area where Tertiary limestones of the Floridan 

aquifer system (specifi cally, the Tampa Member of the Arcadia Formation) 

occur at or near the land surface. In addition to a few springs, this area is 

characterized by scattered karst depressions (sinkholes and sinkhole lakes) 

and subsurface conduits, one of which links Tarpon Spring to Tarpon 

Lake. South of Palm Harbor, the Tertiary limestones dip gradually to the 

west and southwest, beneath a thickening wedge of Quaternary to Recent 

coastal sediments.

Ground water discharges along the Pinellas County coastline to 

the south are considerably lower than those to the north, and primarily represent surfi cial aquifer system seepage into area canals and inland 

water bodies. Land use patterns in most of the southern portion of the 

planning unit are almost completely dominated by urban, residential, and 

 commercial uses.

Crystal Beach Submarine Spring, the southernmost signifi cant spring 

in the basin, discharges brackish water into the Intracoastal Waterway; the 

vent is located about 1,000 feet (300 meters) offshore from the community 

of Crystal Beach. The spring is fed from Floridan aquifer system water 

mixed with seawater, and the explored cave extends to the northeast of the 

vent under dry land (Garman, 1999). It contains an interesting mix of 

salt-tolerant troglobitic invertebrates and microorganisms and is somewhat 

representative of similar troglobitic communities present in many Springs 

Coast Basin springs that straddle the fresh water-salt water transition zone.

The median nitrate+nitrite concentration for 12 Floridan aquifer 

system wells in the planning unit is 0.04 mg/L, near historical statewide 

background concentrations. Nitrate+nitrite data from 5 surfi cial aquifer 

system wells in the planning unit is 0.03 mg/L (Table 4.1). Water quality 

data from basin springs are limited; the median nitrate/nitrate value from 

5 spring stations in the basin (from Health and Crystal Beach Submarine 

Spring) is 6.0 mg/L, the highest of all springs in the basin (Table 4.2).

The ammonia median of 0.24 mg/L from 12 Floridan aquifer system 

wells represents the highest values of any planning unit in the basin and 

is likely the result of localized sources. The median value of 0.31 mg/L 

from 5 surfi cial aquifer system wells is likewise higher than any other basin 

 planning unit.

Orthophosphate values from 2 springs in the Anclote River/Coastal 

Pinellas County Planning Unit had a median concentration of 0.07 mg/L; 

however, one of these springs (Health) had a value exceeding 0.1 mg/L. 

Twelve Floridan aquifer system wells in the planning unit produced a 

median value of 0.004 mg/L; however, wells located in northern Pinellas 

County produced orthophosphate values in excess of 0.1 mg/L. Five surfi -

cial aquifer system wells in the planning unit had a median orthophosphate 

concentration of 0.036 mg/L.

112 Water Quality Assessment Report: Springs Coast
The DO median value for 12 Floridan aquifer system wells in the 

planning unit was 0.66 mg/L. Five surfi cial aquifer system wells in the 

 planning unit had a measured DO level of 0.21 mg/L.

According to the draft Group 5 Verifi ed List (July 2006), several 

WBIDs in the Anclote River/Coastal Pinellas County Planning Unit are 

impaired for potential ground water-sourced analytes. Beginning in the 

northwestern portion of the planning unit, WBID 1440A (Spring Bayou 

Creek) and the adjacent WBID 1508 (Klosterman Bayou Run Tidal) are 

both listed for low DO and elevated nutrients. The DO listing is based 

on high BOD. Median total nitrogen values were 0.77 and 0.98 mg/L, 

respectively, and median total phosphorus values were 0.1 and 0.165 mg/L, 

respectively (typical average estuarine total nitrogen and total phosphorus values are 0.8 mg/L and 0.1 mg/L, respectively [U.S. Environmental 

Protection Agency (EPA), 2007]). Median BOD values were 2.0 and 

2.9 mg/L, respectively.

Based on elevated well and spring ground water values, and the location 

of these waterbodies in a ground water discharge area, ground water contributions to these surface waterbodies could at least be partially responsible 

for the verifi ed listings. The EPA has published a TMDL for Klosterman 

Bayou Run Tidal (EPA, 2007), calling for nutrient reductions for total 

nitrogen and total phosphorus.

WBID 1538 (Curlew Creek Estuary) is listed for elevated fecal coliforms and elevated nutrients, and although it might receive some nutrient 

infl ux from ground water discharge, this is an unlikely source due to the 

WBID’s location and the nature of this estuarine system. There are no data 

to associate the high coliform measurements with a ground water source. 

A number of WBIDs in the western half of the Pinellas Peninsula are 

listed for high nutrients and low DO: WBID 1567 (Stevenson Creek), 

WBID 1668A (St. Joe Creek), WBID 1668B (Pinellas Park Ditch No. 5), 

WBID 1668E (St. Joe Creek Tidal Estuary), and WBID 1709F (Frenchmann’s Creek Basin). Two of these (WBIDs 1668A and 1668B) have 

TMDLs set by the EPA (EPA, 2007). All are listed as high or medium 

priority for TMDL development.

In each case, total phosphorus and nitrogen are elevated compared with 

expected values. For total phosphorus, the range of values for these WBIDs 

was 0.07 to 0.22 mg/L, and the median value was 0.12 mg/L, which is 

comparable to the median surfi cial aquifer well total phosphorus value of 

0.13 mg/L. Natural phosphorus leaching from the Hawthorn Group, present in places near the surface in this area, could be a source of this nutrient.

However, the range of total nitrate values for these WBIDs was 0.93 to 

1.30 mg/L, with a median value of 1.18 mg/L—nearly an order of magnitude above the median surfi cial aquifer well total nitrate+nitrite value of 

0.13 mg/L (Table 4.1). Due to the nature of the surfi cial aquifer system 

lithology along the lower Pinellas Peninsula (interlayered sands, sandy shell 

beds, clayey sands, and sandy clays), any ground water contributions would 

likely represent recent recharge and would be low in volume compared with 

Floridan aquifer system contributions to surface waterbodies to the north. 

The shallow ground water contribution could still be a factor to consider 

in the allocation of phosphorus loads in TMDL development for some 

Water Quality Assessment Report: Springs Coast 113
surface waters in the planning unit, because it is not uncommon for ground 

water basefl ow to account for more than 50 percent of the fl ow in Florida 

streams.

Recommendations 

High nitrate contributions, primarily from Floridan aquifer system 

springs in the northern four planning units, are the most insidious effects 

of ground water discharge into surface waterbodies of the upper and middle 

Springs Coast Basin. Unlike phosphorus, nitrate is a conservative analyte, 

with no signifi cant breakdown or uptake once it enters the aquifer. Nitrate 

loads delivered by the springs have resulted in signifi cant ecological imbalances in many of the receiving waters. These have manifested as extensive 

algal growth, algal blooms, the overgrowth of invasive plants, and the 

depletion of natural aquatic vegetation.

Several previous studies, notably those by Jones, Upchurch, Champion, and DeWitt (1997) and Jones, Upchurch, and Champion (1998), 

have found that inorganic fertilizers are the primary sources of nitrogen 

in the Floridan aquifer system ground waters of this region. Land use has 

changed rapidly over the last 50 years with population growth, resulting 

in an explosion of subdivision development adjacent to and upgradient 

of large coastal springs. These areas have well-drained sandy soils low in 

natural nutrients, and fertilizers have been used to make turfgrass and 

other plants thrive.

With the transition from natural woodlands to watered and fertilized 

lawns, golf courses, and in some areas septic tanks, nitrate sources are now 

present that did not previously exist. The sandy, well-drained soils of the 

Gulf Coastal Lowlands and portions of the Brooksville Ridge are naturally 

low in organic content, and precipitation falling in this region can easily 

and rapidly leach nutrients from fertilized turf down through the sandy 

soils and directly into the Floridan aquifer system. Most of the conduit 

systems feeding these springs are shallow and thus even more likely to pick 

up near-surface nutrients from these land uses. 

To reverse the trend of high nitrate levels in area surface and ground 

water, an intense nutrient management program should be instituted for 

the four northern planning units. Elements of this program could include 

the development of effective turfgrass best management practices (BMPs) 

specifi c to the region, the required use of slow-release or organic fertilizers, 

and the use of xeriscaping or native ground covers in place of traditional 

turf, because these require less fertilizer and water to thrive.

Despite the traditional triggers that elevate a WBID to listed and/or 

verifi ed status, there are no nutrient-impaired waterbodies on the Springs 

Coast Verifi ed List for the 4 northern planning units. However, it has been 

documented in numerous scientifi c studies that rapid biological changes 

have occurred in virtually all of these coastal spring-fed surface waterbodies. Native submerged aquatic vegetation has disappeared altogether 

in many locations or been replaced with invasive species and algal mats. 

Visibility in some spring-fed waterbodies has declined due to chlorophyll 

114 Water Quality Assessment Report: Springs Coast
in the water. According to Stevenson et al. (2007), decreasing nitrate levels 

below 0.25 mg/L or lower will begin to discourage algae growth in spring 

runs. A regular periodic biological assessment program should be initiated in Kings Bay, the Homosassa River, the Chassahowitzka River, and 

the Weeki Wachee River, much like those already being performed by the 

Department in other Florida spring runs. 

Signifi cant ground water input to surface waterbodies is most likely in 

the northern Verifi ed List waterbodies in the Anclote River/Coastal Pinellas 

County Planning Unit. Steps like those described above might be applicable in these WBIDs, but it is likely that other infl uences are more important 

in this area, including poorly maintained septic systems and stormwater 

effects. Ground water effects on Verifi ed List WBIDs in the southern portion of the planning unit are likely overshadowed by other factors.

Chapter 5: The Verified List of Impaired 

Waters

Public Participation

The Florida Department of Environmental Protection (Department) 

has worked with a variety of stakeholders and held public meetings on 

developing and adopting the Verifi ed Lists of impaired waters for the six 

Group 5 basins across the state. Table 5.1 lists the statewide schedule for 

the development and adoption of the Group 5 Verifi ed Lists, including the 

public meetings. The schedule for the Springs Coast Basin is highlighted 

in boldface type.

Basin-specifi c draft Verifi ed Lists of waters that met the requirements of 

the Impaired Surface Waters Rule (IWR) were made available to the public. 

The lists were placed on the Department’s Total Maximum Daily Load 

(TMDL) Program Web site, at http://www.dep.state.fl .us/water/tmdl, and 

were also sent on request to interested parties by mail or via e-mail.

Citizens were given the opportunity to comment on the draft lists in 

person and/or in writing. Public meetings were held across the state to 

encourage public participation on a basin-by-basin basis. The Department 

also accepted written comments for 45 days.

Following the public meetings for the Group 5 basins, revised draft 

lists were made available to the public, who had the opportunity to comment on these revised lists either in writing and/or at a fi nal public meeting 

in Tallahassee. Comments on any of the lists were accepted and considered 

throughout the full comment period. The fi nal basin-specifi c Verifi ed Lists 

developed through the public participation process are adopted by Secretarial Order and submitted to the U.S. Environmental Protection Agency 

(EPA) as the state’s current 303(d) list of impaired waters.

Identification of Impaired Waters

As discussed in Chapter 2, waters on the Verifi ed and Planning Lists 

must meet specifi c thresholds and data suffi ciency and data quality requirements in the IWR (Rule 62-303, Florida Administrative Code [F.A.C.]). 

Appendix A describes the legislative and regulatory background for the 

development of the Planning and Verifi ed Lists. Appendix D contains a 

methodology that describes the criteria and thresholds required for both 

lists under the IWR.

Any waters that do not have suffi cient data to be analyzed in accordance with the requirements of the IWR will remain on the 1998 303(d) 

list of impaired waters maintained by the EPA. These waters are not 

delisted, and they will be sampled during the next phases of the watershed 

management cycle so that their impairment status can be verifi ed.

Documentation of Reasonable Assurance

Under the Florida Watershed Restoration Act, the Department will 

not place impaired waters on the Verifi ed List if reasonable assurance is 

provided that these waters will attain water quality standards in the future 

and will make reasonable progress toward attaining water quality standards by the time the next 303(d) list of impaired waters is scheduled to be 

submitted to the EPA. Reasonable assurance can be provided if existing or 

proposed technology-based effl uent limitations and other pollution control 

programs under local, state, or federal authority are expected to result in 

the attainment of water quality standards. Examples include Surface Water 

Improvement and Management Program restoration projects that provide 

ongoing monitoring, and permitted facilities that upgrade to advanced 

treatment or remove discharges to surface waters. Table 5.2 lists the major 

elements of reasonable assurance, and Appendix C provides additional 

information.

As part of the 303(d) assessment of the Springs Coast Basin, the 

Department received documentation from Pinellas County designed to 

provide reasonable assurance that proposed pollution control mechanisms 

would effectively address the nutrient-related impairment of Lake Seminole. While the fi nal agency action on this submittal will not occur until 

adoption of the Verifi ed List of impaired waters for the Group 5 basins, the 

Department has concluded that the Lake Seminole Reasonable Assurance 

Plan (plan) provides reasonable assurance that the lake will be restored. 

As such, the Department will approve the reasonable assurance proposal 

as part of the list adoption and will place Lake Seminole in assessment 

Category 4b.

The Verified List of Impaired Waters

Table 5.3 contains the Verifi ed List of impaired waters for the Springs 

Coast Basin, based on the water quality assessment performed using IWR 

Run 29, as of September 17, 2007. Figure 5.1 shows waters on the Verifi ed List for the entire basin as of September 17, 2007, and the projected 

year for TMDL development. For presentation purposes, the entire watershed for the listed water is highlighted. However, only the main waterbody 

in the assessment unit has been assessed, and other waters in the watershed 

may not be impaired.

During Phase 2 of the basin management cycle, draft Verifi ed Lists 

for all 6 Group 5 basins go out to the public in the summer. Following a 

series of public meetings and an extended period for public comment, the 

Department’s Secretary generally adopts the Verifi ed List for each basin in 

the fall. Subsequently, errors and omissions to the list are corrected, and 

the Secretary signs an order amending the Verifi ed List. Each order is offi -

cially noticed in the Florida Administrative Weekly; this initiates a 21-day 

period to fi le a petition challenging the order and a 30-day period to appeal 

the order.

Class II: Shellfish propagation or harvesting

Class III: Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife

Class IV: Agricultural water supplies

Class V: Navigation, utility, and industrial use (there are no state waters currently in this class) 2Priority and schedule reflect the priority established for the WBID in the 1998 303(d) list. Where a parameter was 1998 303(d)

listed, the priority shown in the 1998 303(d) list was retained if it was originally high, or changed to medium if it was originally 

low. In the case of mercury in fish, the priority remains low. Where a parameter was only identified as impaired under the IWR, 

priorities of high, medium, or low were used.

134 Water Quality Assessment Report: Springs Coast
Pollutants Causing Impairments

Of the 160 water segments in the Springs Coast Basin, 35 waters are 

impaired for at least 1 parameter, and a TMDL is required for these waters. 

There are a total of 56 parameter listings for impairment following the 

methodology in Appendix D. The Anclote River/Coastal Pinellas County 

Planning Unit has the largest number of impaired parameter listings 

with 45, followed by the Middle Coastal Planning Unit with 6 listings. 

Table 5.4 summarizes the major parameters for which potential impairments were identifi ed.

The most common parameter causing impairment throughout the 

Springs Coast Basin is fecal coliforms with 20 listings, followed by dissolved oxygen (DO) with 19 listings, and nutrients (chlorophyll a) with 

13 listings. There are also 57 segments listed due to fi sh consumption 

advisories for mercury in fi sh; this includes coastal waterbody identifi cation 

numbers in the Middle Coast Planning Unit as well as the freshwater segment Lake Nash. The state has also issued limited consumption advisories 

for king mackerel (Scomberomorus cavalla) and bull shark (Carcharhinus 

leucas) which applies to fi sh species having mercury levels of 0.5 to 1.5 parts 

per million.

Table 5.4 shows that DO levels exceeding criteria are a potential cause 

of impairment in a number of waterbody segments in the basin. As previously mentioned, low DO levels are often natural and not always attributable to pollutants. For this reason, additional work was conducted to 

differentiate between pollutant-related and other causes of low DO before 

the Verifi ed List for the basin was developed.

As required by the IWR, the Department must identify the pollutants causing or contributing to DO exceedances in order to place DO on

the Verifi ed List. If a water segment is on the Verifi ed List for both DO 

and nutrients, nutrients are identifi ed as a pollutant contributing to DO 

exceedances. The Department also applies the following analysis to identify the pollutant(s) contributing to DO exceedances:

1. The waterbody segment median values for biological oxygen 

demand, total nitrogen (TN), and total phosphorus (TP) are 

 determined for the verifi ed period (i.e., January 1, 1999, to 

June 30, 2006).

2. The median values are then compared with the screening levels 

for the appropriate waterbody type. The screening levels represent 

the 70th percentile value of data collected from streams, lakes, or 

 estuaries (Table 5.5). 

3. If a waterbody segment’s median value exceeds the screening 

level, the parameter is identifi ed as a pollutant contributing to the 

exceedances.

Lakes 2.9 1.7 0.11

Source: Friedemann and Hand, 1989.

Table 5.6 provides the median values for waterbody segments where 

there is a suffi cient number of DO exceedances to place the water on the 

Verifi ed List. If a water has a suffi cient number of exceedances for placement on the Verifi ed List, but the median values are less than the screening 

levels, the DO for that segment is included on the Planning List.

Additionally, to place a waterbody segment on the Verifi ed List for 

nutrients, the Department must identify the limiting nutrient or nutrients 

on the Verifi ed List, as required by the IWR. The following method is 

used to identify the limiting nutrient(s) in streams and lakes:

1. The ratios of TN to TP are calculated for each paired value of TN 

and TP (per sampling event) collected during the verifi ed period.

2. The individual ratios over the entire verifi ed period are evaluated to 

determine the limiting nutrient(s). If all the sampling event ratios 

are less than 10, nitrogen is identifi ed as the limiting nutrient, and 

if all the ratios are greater than 30, phosphorus is identifi ed as the 

limiting nutrient. Both nitrogen and phosphorus are identifi ed as 

limiting nutrients if the ratios are between 10 and 30.

Table 5.7 displays the nitrogen and phosphorus ratios for stream and 

lake segments potentially impaired by nutrients.

Listing Based on Other Information Indicating Nutrient 

Imbalance

In the Anclote River/Coastal Pinellas County Planning Unit, there 

are 14 waterbodies impaired for DO requiring TMDLs where the causative pollutant can be traced to a nutrient imbalance. These include

• WBID 1440A, nitrogen is the limiting nutrient (TN/TP ratio of 

8.2). Annual average chlorophyll a values exceeded the threshold in 

1999, 2001, and 2002.

• WBID 1508, nitrogen is the limiting nutrient (TN/TP ratio of 

3.16). Annual average chlorophyll a values exceeded threshold in 

1999–2005.

• WBID 1512Z, the verifi ed period TN median = 5.53 mg/L. 

Note that chlorophyll a is not impaired.

• WBID 1538, nitrogen is the limiting nutrient (TN/TP ratio of 

7.9). Annual average chlorophyll a exceeded threshold in 

1999–2004.

Adoption Process for the Verified List of Impaired Waters

The Verified List must be submitted in a specifi c format (Section 

62-303.710, F.A.C.) before being approved by order of the Department’s 

Secretary. The list must specify the pollutant and concentration causing 

the impairment. If a waterbody segment is listed based on water quality 

 criteria exceedances, then the list must provide the applicable criteria. 

However, if the listing is based on narrative or biological criteria, or impairment of other designated uses, and the water quality criteria are met, the 

Verifi ed List is required to specify the concentration of the pollutant relative to the water quality criteria and explain why the numeric criterion is 

not adequate.

For waters with exceedances of the DO criteria, the Department must 

identify the pollutants causing or contributing to the exceedances and list 

both the pollutant and DO in the Verifi ed List.

For waters impaired by nutrients, the Department is required to 

 identify whether nitrogen or phosphorus, or both, are the limiting nutrients, and specify the limiting nutrient(s) in the Verifi ed List.

The Verifi ed List must also include the priority and schedule for 

TMDL development established for a waterbody segment and note any 

waters that are being removed from the current Planning List. In future 

watershed management cycles, the list must also note waters that are being 

removed from any previous Verifi ed List for the basin. 

Water Quality Assessment Report: Springs Coast 139

Chapter 6: TMDL Development, Allocation, 

and Implementation

Prioritization of Listed Waters

Following the identifi cation of impaired waters on the 303(d) list, the 

Florida Department of Environmental Protection (Department) determines 

priorities for developing total maximum daily loads (TMDLs) in Phase 3 of 

the watershed management cycle. When TMDLs are established, general 

allocations of pollutant load reductions are identifi ed, at least to the level of 

point and nonpoint source categories.

Because TMDLs cannot be developed for all listed waters during 

a single watershed management cycle, waterbodies will be prioritized 

using the criteria in the Impaired Surface Waters Rule (IWR) (Section 

62-303.500, Florida Administrative Code). The rule states that, when 

establishing the TMDL development schedule for waters on the Verifi ed 

List, the Department will prioritize impaired waterbody segments according to the severity of the impairment and each waterbody’s designated 

uses, taking into account the most serious water quality problems, the 

most valuable and threatened resources, and the risk to human health and 

aquatic life.

Under the IWR, the determination of high-, low-, and medium-

 priority waters is based on the following criteria.

High-priority waters:

• Waterbody segments where the impairment poses a threat to potable 

water supplies or human health;

• Waterbody segments where the impairment is due to a pollutant 

regulated by the Clean Water Act and the pollutant has contributed to the decline or extirpation of a federally listed threatened or 

endangered species, as indicated in the Federal Register listing the 

species; or 

• Waterbody segments verifi ed as impaired that are included on the 

U.S. Environmental Protection Agency’s (EPA’s) 1998 303(d) list as 

high priority.

Low-priority waters:

• Waterbody segments that are listed before 2010 because of fi sh consumption advisories for mercury in fi sh (due to the current insuffi -

cient understanding of how mercury cycles in the environment);

Water Quality Assessment Report: Springs Coast 141
• Canals, urban drainage ditches, and other artifi cial waterbody 

 segments that are listed only due to exceedances of dissolved oxygen 

(DO) criteria; or 

• Waterbody segments that were not on the Planning List but were 

identifi ed as impaired during Phase 2 of the watershed management 

cycle and were included on the Verifi ed List, unless the segment 

meets the second high-priority criterion.

• The EPA has also proposed assigning to this category the list of additional waterbody segments that the agency developed using its own 

evaluation methodology, until the Department has had the opportunity to investigate these waterbodies further.

All segments not designated high or low priority are medium priority, 

and are prioritized based on the following factors:

• The presence of Outstanding Florida Waters;

• The presence of waterbody segments that fail to meet more than one 

designated use, i.e., aquatic life, primary contact and recreation, fi sh 

and shellfi sh consumption, drinking water, and the protection of 

human health;

• The presence of waterbody segments that exceed an applicable water 

quality criterion or alternative threshold with a frequency of greater 

than 25 percent at a minimum confi dence level of 90 percent;

• The presence of waterbody segments that exceed more than one 

applicable water quality criterion; or

• Administrative needs of the TMDL Program, including meeting a 

TMDL development schedule agreed to with the EPA, basin priorities related to the Department’s watershed management approach, 

and the number of administratively continued permits in the basin.

The Department is adhering to the TMDL schedule established in the 

Consent Decree between the EPA and Earthjustice for waters on the 1998 

303(d) list that are also identifi ed as impaired under the IWR.

Table 6.1 lists the high-priority waters for TMDL development in the 

Springs Coast Basin. The nine waters listed in the table were also high 

priorities on the 1998 303(d) list. Of these, four segments had suffi cient 

water quality information to verify a parameter as the cause of impairment: 

DO, fecal coliforms, and nutrients (chlorophyll a) for Klosterman Bayou 

Tidal; DO and nutrients (chlorophyll a) for Stevenson Creek Tidal; DO, 

fecal coliforms, and nutrients (chlorophyll a) for St. Joe Creek; and DO, 

fecal coliforms, and nutrients (chlorophyll a) for Pinellas Park Ditch No. 5. 

The Department could not verify the remaining impairments, and the 

establishment of those TMDLs will be the EPA’s responsibility.

* All of the waters included in Table 6.1 are classified as high priority under the category of assessment status with 2006 as 

the priority year for TMDL development. Note also that the EPA will establish TMDLs for those parameters that could not be 

verified impaired.

Total Maximum Daily Load Development

During Phase 3 of the watershed management cycle, TMDLs will be 

developed for both point and nonpoint sources of pollutants in impaired 

waterbodies and will be adopted by rule at the end of this phase.

TMDL development involves determining the maximum amount of 

a given pollutant that a waterbody can assimilate and still meet the applicable numeric or narrative water quality criterion for the pollutant. In 

most cases, this “assimilative” capacity will be determined using computer 

modeling (both hydrodynamic and water quality models) that predicts the 

fate and transport of pollutants in the receiving waters. Modeling for the 

typical TMDL will include model setup, calibration, and verifi cation, followed by a variety of model runs that determine the assimilative capacity of 

the water under worst-case conditions.

State law and federal regulations require that TMDLs include a margin 

of safety (MOS) that takes into account “any lack of knowledge concerning 

the relationship between effl uent limitations and water quality” (Section 

303[d][1][C], Clean Water Act). The EPA has allowed states to establish 

either a specifi c MOS (typically some percentage of the assimilative capacity) or an implicit MOS based on conservative assumptions in the modeling. To date, the Department has elected to establish an implicit MOS 

based on predictive model runs that incorporate a variety of conservative 

assumptions. (They examine worst-case ambient fl ow conditions and worstcase temperature, and assume that all permitted point sources discharge at 

their maximum permitted amount.)

Water Quality Assessment Report: Springs Coast 145
It is important to note that TMDLs will be developed only for the 

actual pollutants causing the impairment in the listed waterbody. These 

are called the “pollutants of concern.” In Florida, the most commonly 

listed pollutants of concern are nutrients, sediments, and coliform bacteria. TMDLs will not be developed for impairments not due to pollutant 

discharges—for example, natural conditions, physical alterations such as 

dams and channelization, or changes in the fl ow of water. In other cases, 

a waterbody may be deemed potentially impaired based on bioassessment 

data or toxicity data. In these cases, the Department must determine the 

actual pollutant causing the impairment before a TMDL can be developed.

Total Maximum Daily Load Allocation and 

Implementation

Initial Allocation of Pollutant Loadings

The Florida Watershed Restoration Act (FWRA) requires that a 

TMDL include the “establishment of reasonable and equitable allocations 

. . . among point and nonpoint sources . . . .” The Department refers to 

this as the “initial allocation,” which is adopted by rule. For the purposes 

of allocating the required pollutant loadings, the term “point sources” 

 primarily includes traditional sources such as domestic and industrial 

wastewater discharges.

Recent EPA guidance requires states to include as point sources those 

stormwater systems that are covered by a National Pollutant Discharge 

Elimination System (NPDES) stormwater permit. However, NPDES-

 permitted stormwater discharges are not subject to the same types of 

 effl uent limitations, cannot be centrally collected and treated, and typically 

have not invested in treatment controls to the same degree as traditional 

point sources. Nonpoint sources include intermittent, rainfall-driven, 

 diffuse sources of pollutants associated with everyday human activities, including runoff from urban land uses, agriculture, silviculture, and 

mining; discharges from failing septic systems; and atmospheric deposition.

These point and nonpoint defi nitions do not directly relate to whether 

a source is regulated. Some nonpoint sources such as stormwater systems 

are permitted under the regulatory programs of the Department or water 

management districts, while others, such as agricultural stormwater discharges, are not. This distinction is important because the implementation 

of the allocations to nonpoint sources outside the authority of regulatory 

programs will require cooperation from dischargers to implement best management practices (BMPs) voluntarily.

While a detailed allocation will ultimately be necessary to implement 

a TMDL fully, a key goal of the initial allocation is to assign responsibility 

for pollutant load reductions between point and nonpoint sources. For 

point sources, allocations will be implemented through the Department’s 

NPDES wastewater and stormwater permitting programs. The implementation of nonpoint source load reductions will be done through a combination of regulatory and nonregulatory processes. 

Initial allocations of pollutant loadings will also be made to historical 

sources (e.g., the phosphorus-laden sediments at the bottom of a lake) and 

146 Water Quality Assessment Report: Springs Coast
upstream sources (those entering into an impaired waterbody). Upstream 

sources include sources outside Florida, and these sources will receive 

reduced allocations similar to in-state sources.

The FWRA provided direction for the allocation of TMDLs and 

directed the Department to provide guidance on the allocation process by 

establishing an Allocation Technical Advisory Committee (ATAC), consisting of representatives of key stakeholder groups. The committee recommended a three-step process for developing initial allocations and addressed 

detailed allocations for nonpoint sources, stakeholder involvement, the use 

of BMPs, and other TMDL implementation issues (Department, 2001). 

Implementation Programs and Approaches 

The FWRA designates the Department as the lead agency in coordinating the implementation of TMDLs. Existing programs and approaches 

through which TMDLs may be carried out include the following:

• Permitting and other existing regulatory programs, such as NPDES 

permits, domestic and industrial wastewater permits, and stormwater/Environmental Resource Permits (Table 6.2 lists the municipal NPDES stormwater permittees in the Springs Coast Basin);

• Local land development codes;

• Nonregulatory and incentive-based programs, including BMPs, cost 

sharing, waste minimization, pollution prevention, new approaches 

to land use design and development, and public education; 

• Basin Management Action Plans (B-MAPs) developed under the 

FWRA;

• Other water quality management and restoration activities, for 

 example, Surface Water Improvement and Management plans 

approved under Section 373.453, Florida Statutes;

• Pollutant trading or other equitable economically based agreements;

• Public works, including capital facilities; or

• Land acquisition.

These programs and approaches will be carried out at local, regional, 

state, and possibly federal levels. TMDL implementation will require 

extensive stakeholder involvement throughout the state and, in some cases, 

between Florida and other states. Appendix A provides additional details 

on the implementation programs and approaches listed here.

Development of Basin Management Action 

Plans

The FWRA authorizes the Department to develop B-MAPs for implementing TMDLs. These plans will be developed with extensive stakeholder input to build consensus on detailed allocations based on the initial 

general allocations to categories of discharges.

The B-MAPs will contain fi nal allocations, strategies for meeting the 

allocations, schedules for implementation, funding mechanisms, applicable 

local ordinances, and other elements. In cases where stakeholder consensus could not be reached on detailed allocations and/or a B-MAP within a 

reasonable time, the Department will develop the allocations.

Once a B-MAP is developed, the Department will make it available for 

public review and comment. Guidance for the content and format of the 

B-MAPs is being developed; the plans are likely to include a description of 

both regulatory and nonregulatory approaches to meeting specifi c TMDLs.

Appendix A: Legislative and Regulatory Background on the 

Watershed Management Approach and the Implementation of 

Total Maximum Daily Loads 

Federal and State Legislation on Surface Water Quality and Total Maximum 

Daily Loads 

Clean Water Act 

Congress enacted the Clean Water Act in 1972 with the goal of restoring and 

maintaining the “chemical, physical, and biological integrity of the nation’s waters” (33 

U.S.C. § 1251[a]). The ultimate goal of the act is to eliminate the “discharge of [all] 

pollutants into navigable waters” (33 U.S.C. § 1251[a][1]). 

Section 305(b) of the Clean Water Act requires states to report biennially to the U.S. 

Environmental Protection Agency (EPA) on their water quality. The 305(b) assessment 

report provides information on the physical, chemical, biological, and cultural features of 

each river basin in Florida. This initial assessment provides a common factual basis for 

identifying information sources and major issues, and for determining the future changes, 

strategies, and actions needed to preserve, protect, and/or restore water quality. 

Understanding the physical framework of each basin allows the development of a 

science-based methodology for assessing water quality and an accurate picture of the 

waters that are most impaired or vulnerable to contamination. 

Section 303(d) of the Clean Water Act requires states to submit to the EPA lists of 

surface waters that do not meet applicable water quality standards and establish total 

maximum daily loads (TMDLs) for each of these waters on a schedule. A pollution limit 

is then allocated to each pollutant source in an individual river basin. 

A TMDL represents the maximum amount of a given pollutant that a waterbody can 

assimilate and meet all of its designated uses (see Noteworthy on Florida’s surface water 

quality classifications for a listing of these classifications). A waterbody that does not 

meet its designated use is defined as impaired. 

NOTEWORTHY: FLORIDA’S SURFACE WATER QUALITY CLASSIFICATIONS 

Florida’s water quality standards program, the foundation of the state’s program of water quality 

management, designates the “present and future most beneficial uses” of the waters of the state 

(Subsection 403.061[10], Florida Statutes [F.S.]). Water quality criteria, expressed as numeric or 

narrative limits for specific parameters, describe the water quality necessary to maintain these 

uses for surface water and ground water. Florida’s surface water is protected for five designated 

use classifications, as follows: 

Class I Potable water supplies 

Class II Shellfish propagation or harvesting 

Class III Recreation, propagation, and maintenance of a healthy, well-balanced 

population of fish and wildlife 

Class IV Agricultural water supplies 

Class V Navigation, utility, and industrial use (there are no state waters currently in 

this class) 
160 Water Quality Assessment Report: Springs Coast

Florida Watershed Restoration Act 

In 1998, the EPA settled a lawsuit with the environmental group Earthjustice over 

Florida’s TMDL Program. The Consent Decree resulting from the lawsuit requires all 

TMDLs on the state’s 1998 Section 303(d) list of impaired waters to be developed in 13 

years. If the state fails to develop the TMDLs, the EPA is required to do so. 

In response to concerns about the TMDL lawsuit and in recognition of the important 

role that TMDLs play in restoring state waters, the 1999 Florida legislature enacted the 

Florida Watershed Restoration Act (FWRA) (Chapter 99-223, Laws of Florida). The act 

clarified the Florida Department of Environmental Protection’s (Department) statutory 

authority to establish TMDLs, required the Department to develop a methodology for 

identifying impaired waters, specified that the Department could develop TMDLs only 

for waters on a future state list of impaired waters developed using this new 

methodology, and directed the Department to establish an Allocation Technical Advisory 

Committee (ATAC) to address the allocation process for TMDLs. The act also declared 

Lake Okeechobee impaired and, as required under the TMDL Consent Decree, allowed 

the state to develop a TMDL for the lake (see Noteworthy for a description of the 

legislation’s major provisions). 

NOTEWORTHY: THE FLORIDA WATERSHED RESTORATION ACT 

The Florida Watershed Restoration Act contains the following major provisions: 

• Establishes that the 303(d) list submitted to the EPA in 1998 is for planning purposes only. 

• Requires the Department to adopt 303(d) listing criteria (that is, the methodology used to 

define impaired waters) by rule. 

• Requires the Department to verify impairment and then establish a Verified List for each 

basin. The Department must also evaluate whether proposed pollution control programs are 

sufficient to meet water quality standards, list the specific pollutant(s) and concentration(s) 

causing impairment, and adopt the basin-specific 303(d) list by Secretarial Order. 

• Requires the Department’s Secretary to adopt TMDL allocations by rule. The legislation 

requires the Department to establish “reasonable and equitable” allocations of TMDLs, but 

does not mandate how allocations will be made among individual sources. 

• Requires that TMDL allocations consider existing treatment levels and management 

practices; the differing impacts that pollutant sources may have; the availability of treatment 

technologies, best management practices (BMPs), or other pollutant reduction measures; the 

feasibility, costs, and benefits of achieving the allocation; reasonable time frames for 

implementation; the potential applicability of moderating provisions; and the extent that 

nonattainment is caused by pollutants from outside Florida, discharges that have ceased, or 

alteration to a waterbody. 

• Required a report to the legislature by February 2001 addressing the allocation process. 
Water Quality Assessment Report: Springs Coast 161

• Authorizes the Department to develop basin plans to implement TMDLs, coordinating with the 

water management districts, the Florida Department of Agriculture and Consumer Services 

(DACS), the Soil and Water Conservation Districts, regulated parties, and environmental 

groups in assessing waterbodies for impairment, collecting data for TMDLs, developing 

TMDLs, and conducting at least one public meeting in the watershed. Implementation is 

voluntary if not covered by regulatory programs. 

• Authorizes the Department and DACS to develop interim measures and BMPs to address 

nonpoint sources. While BMPs would be adopted by rule, they will be voluntary if not 

covered by regulatory programs. If they are adopted by rule and the Department verifies their 

effectiveness, then implementation will provide a presumption of compliance with water 

quality standards. 

• Directs the Department to document the effectiveness of the combined regulatory/voluntary 

approach and report to the legislature by January 1, 2005. The report will include 

participation rates and recommendations for statutory changes. 

Determining Impairment Based on the State’s Impaired Surface Waters Rule 

Section 303(d) of the federal Clean Water Act and the FWRA describe impaired 

waters as those waterbodies or waterbody segments that do not meet applicable water 

quality standards. “Impairment” is a broad term that includes designated uses, water 

quality criteria, the Florida antidegradation policy, and moderating provisions (see 

Noteworthy for explanations of these terms). 

The state’s Identification of Impaired Surface Waters Rule (IWR) (Rule 62-303, 

Florida Administrative Code [F.A.C.]) was developed in cooperation with a Technical 

Advisory Committee and adopted by the Florida Environmental Regulation Commission 

on April 26, 2001. It provides a science-based methodology for evaluating water quality 

data in order to identify impaired waters, and establishes specific criteria for impairment 

based on chemical parameters, the interpretation of narrative nutrient criteria, biological 

impairment, fish consumption advisories, and ecological impairment. The complete text 

of the rule is available at http://www.dep.state.fl.us/legal/Rules/shared/62-303/62-

303.pdf. 

The IWR also establishes thresholds for data sufficiency and data quality, including 

the minimum sample size required and the number of exceedances of the applicable 

water quality standard for a given sample size that identify a waterbody as impaired. The 

number of exceedances is based on a statistical approach designed to provide greater 

confidence that the outcome of the water quality assessment is correct. Waters that are 

identified as impaired through the IWR are prioritized for TMDL development and 

implementation. 
162 Water Quality Assessment Report: Springs Coast

NOTEWORTHY: EXPLANATION OF TERMS 

• Designated uses, discussed in an earlier sidebar, comprise the five classifications applied to 

each of the state’s surface waterbodies.

• Water quality criteria comprise numeric or narrative limits of pollutants. 

• The Florida Antidegradation Policy (Sections 62-302.300 and 62-4.242, F.A.C.) recognizes 

that pollution that causes or contributes to new violations of water quality standards or to the 

continuation of existing violations is harmful to the waters of the state. Under this policy, the 

permitting of new or previously unpermitted existing discharges is prohibited where the 

discharge is expected to reduce the quality of a receiving water below the classification

established for it. Any lowering of water quality caused by a new or expanded discharge to 

surface waters must be in the public interest (that is, the benefits of the discharge to public 

health, safety, and welfare must outweigh any adverse impacts on fish and wildlife or 

recreation). Further, the permittee must demonstrate that other disposal alternatives (for 

example, reuse) or pollution prevention are not economically and technologically reasonable 

alternatives to the surface water discharge. 

• Moderating provisions (provided in Subsection 62-302.300[10] and Rules 62-4 and 62-6, 

F.A.C., and described in Sections 62-302.300, 62-4.244, 62-302.800, 62-4.243, F.A.C., and 

Sections 403.201 and 373.414, F.S.) include mixing zones, zones of discharge, site-specific 

alternative criteria, exemptions, and variances. These provisions are intended to moderate 

the applicability of water quality standards where it has been determined that, under certain 

special circumstances, the social, economic, and environmental costs of such applicability 

outweigh the benefits. 

Determining impairment in individual waterbodies takes place in two phases. First, 

in each river basin the Department evaluates the existing water quality data, using the 

methodology prescribed in the IWR, to determine whether waters are potentially 

impaired. Waters found to be potentially impaired are included on a Planning List for 

further assessment under Subsections 403.067(2) and (3), F.S. As required by Subsection 

403.067(2), F.S., the Planning List is not used to administer or implement any regulatory 

program. It is submitted to the EPA for informational purposes only. 

The second step is to assess waters on the Planning List under Subsection 

403.067(3), F.S., as part of the Department’s watershed management approach (described 

in the following section). The Department carries out additional data gathering and 

strategic monitoring, focusing on these potentially impaired waters, and determines—

using the methodology in Part III, Section 62-303.400, F.A.C.—if a waterbody is, in fact, 

impaired and if the impairment is caused by pollutant discharges. 

A Water Quality Assessment Report is produced containing the results of this 

updated evaluation and a Verified List of impaired waters. The criteria for the Verified 

List are more stringent than those for the Planning List. The Department is required to 

develop TMDLs for waters on the Verified List under Subsection 403.067(4), F.S. A 

watershed management plan (called a Basin Management Action Plan, or BMAP) to 
Water Quality Assessment Report: Springs Coast 163

reduce the amount of pollutants that cause impairments must also be produced and 

implemented. 

The Verified List is adopted by Secretarial Order in accordance with the FWRA. 

Once adopted, the list is submitted to the EPA for approval as the state’s Section 303(d) 

list of impaired waters for the basin. 

Implementing Total Maximum Daily Loads 

The Watershed Management Approach 

The Department's statewide approach to water resource management, called the 

watershed management approach, is the framework for implementing TMDLs as required 

by the federal and state governments. The approach does not focus on individual causes 

of pollution. Instead, each basin is assessed as an entire functioning system, and aquatic 

resources are evaluated from a basinwide perspective that considers the cumulative 

effects of human activities. Water resources are managed on the basis of natural 

boundaries, such as river basins, rather than political or regulatory boundaries. Federal, 

state, regional, tribal, and local governments identify watersheds not meeting clean water 

or other natural resource goals and work cooperatively to focus resources and implement 

effective strategies to restore water quality. Extensive public participation in the 

decision-making process is crucial. 

The watershed management approach is not new, nor does it compete with or replace 

existing programs. Rather than relying on single solutions to water resource issues, it is 

intended to improve the health of surface water and ground water resources by 

strengthening coordination among such activities as monitoring, stormwater 

management, wastewater treatment, wetland restoration, land acquisition, and public 

involvement. 

By promoting the management of entire natural systems and addressing the 

cumulative effects of human activities on a watershed basis, this approach is intended to 

protect and enhance the ecological structure, function, and integrity of Florida’s 

watersheds. It provides a framework for setting priorities and focusing the Department’s 

resources on protecting and restoring water quality, and aims to increase cooperation 

among state, regional, local, and federal interests. By emphasizing public involvement, 

the approach encourages stewardship by all Floridians to preserve water resources for 

future generations. 

The watershed approach is intended to speed up projects by focusing funding and 

other resources on priority water quality problems, strengthening public support, 

establishing agreements, and funding multiagency projects. It avoids duplication by 

building on existing assessments and restoration activities and promotes cooperative 

monitoring programs. It encourages accountability for achieving water quality 

improvements through improved monitoring and the establishment of TMDLs. 
164 Water Quality Assessment Report: Springs Coast

The Watershed Management Cycle 

As part of the Department’s watershed management approach, TMDLs will be 

developed, and the corresponding pollutant loadings allocated, as part of a watershed 

management cycle that rotates through the state’s 52 river basins over a 9-year period. 

The cycle’s 5 phases are as follows: 

• Phase 1: Preliminary Watershed Evaluation. For each river basin, a Water 

Quality Status Report is developed, containing a Planning List of potentially 

impaired waters that may require the establishment of TMDLs. The report 

characterizes each basin’s hydrologic, ecological, and socioeconomic setting as well 

as historical, current, and proposed watershed management issues and activities. It 

also contains a preliminary evaluation of major water quality parameters, water 

quality issues by planning unit, ecological resources, and basinwide pollutant loading 

trends related to land uses. At the end of Phase 1, a Strategic Monitoring Plan is 

developed. 

• Phase 2: Strategic Monitoring and Assessment. Additional data are collected 

through strategic monitoring and uploaded to STORET. The data are used to verify 

whether potentially impaired waters in each basin are impaired and to calibrate and 

verify models for TMDL development. At the end of Phase 2, a Water Quality

Assessment Report is produced for each basin that contains a Verified List of 

impaired waters. The report also provides an updated and more thorough evaluation 

of water quality, associated biological resources, and current management plans. The 

Department will adopt the Verified List through a Secretarial Order and submit it to 

the EPA as the state’s Section 303(d) list of impaired waters. 

• Phase 3: Development and Adoption of TMDLs. TMDLs for priority impaired 

waters in the basin will be developed and adopted by rule. Because TMDLs cannot 

be developed for all listed waters during a single watershed management cycle due to 

fiscal and technical limitations, waterbodies will be prioritized using the criteria in the 

IWR (Rule 62-303, F.A.C.). 

• Phase 4: Development of a Basin Management Action Plan. A BMAP will be 

developed for each basin to specify how pollutant loadings from point and nonpoint 

sources will be allocated and reduced in order to meet TMDL requirements. The 

plans will include regulatory and nonregulatory (i.e., voluntary) and structural and 

nonstructural strategies, and existing management plans will be used where feasible. 

The involvement and support of affected stakeholders in this phase will be especially 

critical. 

• Phase 5: Implementation of a Basin Management Action Plan. Implementation of 

the activities specified in the BMAP will begin. This includes carrying out rule 

development as needed, securing funding, informing stakeholders and the public, and 

monitoring and evaluating the implementation of the plan. 
Water Quality Assessment Report: Springs Coast 165

To implement the watershed cycle, the state’s river basins have been divided into 

five groups within each of the Department’s six districts statewide, and each district will 

assess one basin each year. Table A.1 shows the basin groups for implementing the 

cycle in the Department’s districts, and Figure A.1 shows these groups and the rotating 

cycle in the districts. Table A.2, which lists the basin rotation schedule for TMDL 

development and implementation, shows that it will take nine years to complete one full 

cycle of the state. 

The watershed management cycle is an iterative, or repeated, process. One of its key 

components is that the effectiveness of management activities (TMDL implementation) 

will be monitored in successive cycles. Monitoring conducted in Phase 2 of subsequent 

cycles will be targeted at evaluating whether water quality objectives are being met and 

whether individual waters are no longer impaired. The Department also will track the 

implementation of scheduled restoration activities, whether required or voluntary, to 

ensure continued progress towards meeting the TMDLs.

Pollutants can enter a waterbody through point source discharges (generally from a 

specific facility) or nonpoint discharges (e.g., stormwater runoff, septic tanks). 

Government agencies, businesses, organizations, and individuals who contribute to these 

discharges will be asked to share the responsibility of attaining TMDLs through load 

allocations (the amount of a specified pollutant allotted for discharge) that are based on 

an established TMDL. Table A.3 summarizes these potentially affected stakeholders, 

and the actions they may be asked to take to help achieve a TMDL.

Permitting and Other Approaches 

NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM PERMITS

All point sources that discharge to surface waterbodies require an NPDES permit. 

These permits can be classified into two types: domestic or industrial wastewater 

discharge permits, and stormwater permits. NPDES-permitted point sources may be 

affected by the development and implementation of a TMDL. All NPDES permits 

include “reopener clauses” that allow the Department to incorporate new discharge limits 

when a TMDL is established. These new limitations may be incorporated into a permit 

when a TMDL is implemented or at the next permit renewal, depending on the timing of 

the permit renewal and workload. For NPDES municipal stormwater permits, the 

Department intends to insert the following statement once a BMAP is completed: 

“The permittee shall undertake those activities specified in the (Name of Waterbody) 

Basin Management Action Plan in accordance with the approved schedule set forth in the 

BMAP.” 
168 Water Quality Assessment Report: Springs Coast

DOMESTIC AND INDUSTRIAL WASTEWATER PERMITS

In addition to NPDES-permitted facilities, all of which discharge to surface waters, 

Florida also regulates domestic and industrial wastewater discharges to ground water via 

land application. Since ground water and surface water are so intimately linked in much 

of the state, reductions in loadings from these facilities may be needed to meet TMDL 

limitations for pollutants in surface waters. If such reductions are identified in the 

BMAP, they would be implemented through modifications of the existing state permits. 

FLORIDA STORMWATER/ENVIRONMENTAL RESOURCE PERMITS

With the implementation of the state’s stormwater treatment rule in 1982, Florida 

became the first state to require the treatment of stormwater from all new development. 

Today, except in the area served by the Northwest Florida Water Management District, 

new development projects receive an Environmental Resource Permit that combines 

stormwater flood protection, stormwater treatment, and wetland protection/mitigation 

into a single permit. These permits are designed to obtain 80 percent average annual load 

reduction of total suspended solids. This level of treatment may need to be increased, 

depending on the allocation of load reductions, especially for nutrients. For example, the 

St. Johns River Water Management District recently adopted basin-specific criteria for 

the Lake Apopka watershed that require the phosphorus loading from new development 

not to exceed predevelopment phosphorus loading. 

LOCAL LAND DEVELOPMENT CODES 

Since structural stormwater treatment practices can only achieve certain levels of 

load reductions, and because the hydrologic changes accompanying urban development 

often cause ecological impacts to aquatic systems, local land development codes that 

promote “low-impact development” are an important component of restoring impaired 

waters. Local codes may need to be reviewed to determine how to promote 

developments that minimize impervious surfaces (such as reduced street widths or the use 

of pervious pavements), promote the protection of vegetation, promote the protection and 

restoration of riparian buffers along streams and lakes, and adopt the principles of the 

Florida Yards and Neighborhoods Program in local landscaping codes. 

BEST MANAGEMENT PRACTICES

5. Typically, BMPs refer to a practice or combination of practices that, based on 

sound science and best professional judgment, are determined to be the most effective 

and practicable means of reducing nonpoint source pollutant discharges and improving 

water quality. Both economic and technological considerations are included in the 

evaluation of what is practicable. BMPs may include structural controls (such as 

retention areas or detention ponds) or nonstructural controls (such as street sweeping or 

public education). Many BMPs have been developed for urban stormwater to reduce 

pollutant loadings and peak flows. These BMPs accommodate site-specific conditions, 

including soil type, slope, depth to ground water, and the designation of receiving waters. 
Water Quality Assessment Report: Springs Coast 169

6. The passage of the FWRA increased the emphasis on implementing BMPs to 

reduce nonpoint source pollutant discharges from agricultural operations. Recognizing 

that the development and adoption of BMPs might take several years, the legislature 

authorized the use of Interim Measures (IMs) during the BMP development process for 

agricultural operations. In essence, IMs are a set of logical conservation practices 

designed to reduce agricultural nonpoint pollutant discharges based on current knowledge 

and best professional judgment. These practices will evolve into more formal BMPs as 

better scientific data on their effectiveness is obtained. 

7. Once DACS adopts BMPs, the Department is charged with verifying their 

effectiveness in reducing agricultural nonpoint sources. Once verified, agricultural 

operations that have implemented BMPs will receive a waiver of liability and 

presumption of compliance similar to that granted a developer who obtains an 

Environmental Resource Permit. 

OTHER STRATEGIES

8. The success of implementing nonpoint source TMDL load allocations will require 

variety, creativity, stakeholder commitment to watershed management, and personal 

stewardship. In addition to BMPs, other possible strategies for meeting TMDLs, 

restoring water quality, and preventing the further degradation of Florida’s watersheds 

include cost sharing, waste minimization, pollution prevention, new approaches to land 

use design and development, and pollutant trading. The Department will assemble a 

Technical Advisory Committee to help develop a pollutant-trading rule, which must be 

reviewed by the legislature prior to its adoption. The Department will also continue to 

work with local stakeholders on TMDL allocation issues and implementation plans.

Appendix B: Supplementary Ecological Information in the 

Springs Coast Basin 

NOTEWORTHY: SOURCES OF INFORMATION

Much of the information about the ecology of the Springs Coast Basin in this appendix was 

excerpted or adapted from An Ecological Characterization of the Florida Springs Coast: 

Pithlachascotee to Waccasassa Rivers (U.S. Department of the Interior, December 1990) and the 

SWFWMD’s Springs Coast Comprehensive Watershed Management Plan (April 2001). 

Saltwater and Coastal Communities 

Marine and coastal environments are shaped by major factors such as geology, 

topography, winds, currents and tides, water depth, water temperature, and water 

chemistry. The following describes the major coastal saltwater habitats and communities 

in the Springs Coast Basin, as well as their associated species. 

ESTUARIES

In most nearshore areas of the basin, the water is less saline than marine water 

because of low wave action and the large quantities of fresh water discharged through 

streams, springs, and sheet flow. Salinity patterns in these inshore waters are estuarine, 

as are the plant and animal species living there. 

Estuaries play an important role in the life cycles of numerous species of fish and 

invertebrates. For example, the young and juvenile populations of many sport and 

commercial species use estuaries as nursery grounds. Of the total commercial fisheries’ 

catch in the Gulf of Mexico states, between 90 and 97 percent of these species use 

estuaries during some phase of their life cycle. 

Along the Springs Coast, there are five dominant intertidal estuarine habitats—

brackish marshes, salt marshes, intertidal flats, oyster reefs, and, to a lesser extent, 

intertidal mangrove forests. 

Brackish marshes. The Springs Coast comprises one of the largest and most 

spectacular mixtures of salt marshes and brackish marshes in Florida. Numerous karst 

features—such as creek channels, circular ponds, bedrock highs, and freshwater 

springs—characterize much of the area. The low-energy, karstic coastline gives rise to 

an intricate mosaic of marshes and coastal hammocks, where small changes in elevation, 

tidal inundation, soil characteristics, and freshwater flow control the various zones of 

vegetation. 

Sawgrass (Cladium jamaicense) primarily dominates the marshes, but cattails (Typha 

spp.) are codominant or dominant in many areas. Large patches of black needlerush 

(Juncus roemerianus) and other herbs interrupt the sawgrass, particularly near the river 

channels. The brackish vegetation is perennial but dies back in the fall, providing organic 

detritus that feeds species at the base of the food chain. Submergent vegetation includes 

a number of freshwater plants that are tolerant of low salinities, such as eelgrass 
Water Quality Assessment Report: Springs Coast 171

(Vallisneria neotropicalis), sago pondweed (Potamogeton pectinatus), and wigeongrass 

(Ruppia maritima). Numerous species of fish and macroinvertebrates use these areas. 

Salt marshes. Salt marshes, which dominate the basin’s coastline, represent a 

transitional zone between terrestrial and marine ecosystems. They develop in the zeroenergy areas along the Springs Coast, where they are protected from waves. Salt marshes 

are highly productive systems because of the large input of nutrients and organic 

particulate matter from tides and river flows, which support abundant quantities of 

phytoplankton, algae, and vascular plants. 

Salt marshes are generally made up of large, homogeneous expanses of dense, 

grasslike species. Along the Springs Coast, black needlerush (Juncus roemerianus) 

predominates. Smooth cordgrass (Spartina alternifloria) is usually restricted to the 

narrow fringes bordering the coastline, the edges of tidal creeks and channels, and small 

islands. Other species present include saltgrass (Spartina patens), marsh spike grass 

(Distichlis spicata), and glasswort (Salicornia perennis).

Cabbage palm (Sabal palmetto), red cedar (Juniperus silicicola), and live oak 

(Quercus virginiana) usually dominate the coastal hammock islands; these are widely 

scattered on limestone outcrops among the Spring Coast’s salt marshes and brackish 

marshes. 

Saltmarsh species are frequently exposed to harsh and variable conditions. 

Conditions in the marsh change with tidal ebbs and flows, resulting in salinity, 

temperature, oxygen, and pH fluctuations. Conditions can also vary from one area to 

another. Some animal species live permanently in the marshes; others use them only 

during certain seasons or stages in their life cycles. 

Fish are seasonally very abundant and diverse. Over 60 species of birds, including 

wading birds and shorebirds, also use the Springs Coast salt marshes for food, nesting 

areas, and refuges. The tricolored heron (Egretta tricolor) is the most abundant species. 

The marshes are also an important wintering area for the largest concentration of redhead 

ducks (Anas acuta) in the southeastern United States and also provide feeding sites for 

bald eagles (Haliaeetus leucocephalus). 

Reptiles and mammals found in the basin’s salt marshes include the Gulf salt marsh 

snake (Nerodia clarkii clarkii), diamondback terrapin (Malaclemys terrapin 

macrospilota), and American alligator (Alligator mississippiensis), the marsh rabbit

(Sylvilagus palustris), marsh rice rat (Oryzomys palustris),hispid cotton rat (Sigmodon 

hispidus), and Duke’s saltmarsh vole (Microtus pennsylvanicus dukecampbelli). 

Intertidal flats. These comprise the portions of the unvegetated bottoms of 

estuaries, bays, lagoons, and river mouths that lie between the high- and low-tide marks. 

Made up of sandy and muddy sediments, they appear barren and unproductive because of 

the absence of macrophytes, such as marshgrasses or seagrasses. However, they contain 

abundant benthic microalgae, bacteria, fungi, and invertebrates; the latter provide food 

for numerous species of birds and crabs. Bird species found in the intertidal flats include 

herons, egrets, ibises, yellowlegs, sandpipers, plovers, godwits, and curlews. Important 

invertebrate predators are fiddler crabs (Uca spp.), blue crabs (Callinectes sapidus),

stingrays (Dasyatis sabina), and horseshoe crabs (Limulus polyphemus).

Oyster reefs. Oysters are typically reef organisms, growing on the shell substrate 

accumulated from previous generations of oysters. In the Springs Coast Basin, they are 
172 Water Quality Assessment Report: Springs Coast

found primarily outside the numerous river mouths. Tides bring in food and carry away 

waste. The reefs range in size from small, scattered clumps to massive, solid mounds of 

living oysters and dead shells. 

Oyster reefs influence estuaries physically by removing suspended particulates and 

altering currents, and biologically by removing phytoplankton and other particles and 

producing large quantities of oyster biomass and pseudofeces. The reef also provides 

habitats for many estuarine organisms. 

The principal oyster species in the Springs Coast Basin are the eastern or American 

oyster (Crassostrea virginica) and the crested oyster (Ostreola equestris). Both species 

grow in a wide range of salinities. Oysters are commercially harvested in Citrus and 

Pasco Counties. 

Oyster reefs usually contain large and diverse numbers of other species, such as 

marine insects (Anurida maritima), barnacles (Balanus improvisus), mud crabs 

(Eurypanopeus depressus and Panopeus herbstii), and various polychaetes, amphipods, 

gastropods, bivalves, mussels, and worms. Stone crabs (Menippe mercenaria) are an 

important commercial fishery along the Springs Coast. The American oystercatcher 

(Haematopus palliatus) is the most important vertebrate predator of oysters in the area. 

Intertidal mangrove forests. Mangroves are mainly found fringing the outer marsh 

islands, especially in the southern portion of the Springs Coast Basin. Three mangrove 

species are present: black mangrove (Avicennia germinans), red mangrove (Rhizophora 

mangle), and white mangrove (Laguncularia racemosa). The black mangrove is found 

throughout Florida’s Gulf Coast and is the most cold resistant; the red mangrove is 

present as far north as Levy County; and the white mangrove occurs as far north as 

Hernando County. 

Mangroves grow in a variety of soils but flourish on muds and fine-grained siliceous 

sands. Wave and current energy control sediment distribution and mangrove 

development. Mangrove forests modify the substrate through peat deposition. Extensive 

populations of fungi on the submerged portions of the prop roots, stems, branches, and 

living and dead leaves convert mangrove leaf material into detritus that can be used by 

other species. Fires play an important role in mangrove succession. Most fires in 

Springs Coast mangrove stands are started by lightning and result in small, circular 

openings in the forest canopy. 

Mangrove forests support diverse algae that attach to the prop roots or live in the 

muddy sediments. Also present is an abundant microscopic community of diatoms and 

dinoflagellates and other filamentous green and blue-green algae. A number of salttolerant vascular plants are found in mangrove stands. These include leather leaves 

(Acrostichum aureum and A. Danaeifolium), chaff flower (Alternanthera ramosissima),

Spanish bayonet (Yucca aloifolia), lianas, and a variety of bromeliads. 

A distinctive and highly diverse group of arthropods, mostly insects, lives in the 

mangrove forests. Other species include the mangrove tree crab (Aratus pisonii), which 

feeds in the mangrove canopy; numerous small invertebrates that graze on the prop-root 

algae; and many other filter feeders and carnivores. The mangrove system also provides 

nursery habitat for the Florida spiny lobster (Panulirus argus). Juveniles are especially 

abundant in the prop-root system, which provides protection and food. Fish species 

found here include killifish (Fundulus confluentus), pinfish, silver perch, pigfish, 
Water Quality Assessment Report: Springs Coast 173

anchovies, snook, ladyfish, tarpon, gar, and mangrove snapper. Some of these are fished 

commercially and recreationally. Amphibians and reptiles include four species of marine 

turtles, three species of lizards (Anolis), and American alligators (Alligator 

mississippiensis). 

In addition, mangroves harbor a diverse bird assemblage: wading birds (herons, 

egrets, ibises, bitterns, and spoonbills), probing shorebirds (clapper rails, willets, and 

black-necked stilts), floating and diving birds (ducks, grebes, loons, cormorants, and 

gallinules), aerially searching birds (gulls, terns, kingfishers, black skimmers, and fish 

crows), birds of prey (hawks, falcons, vultures, and owls), and arboreal birds (pigeons, 

cuckoos, woodpeckers, flycatchers, thrushes, vireos, warblers, blackbirds, and sparrows). 

MARINE AREAS

Open-water estuarine areas. These areas are characterized by extreme spatial 

variability, based on daily and seasonal fluctuations in local salinity and temperature, and 

wind and tidal mixing. 

Abundant phytoplankton and zooplankton serve as the base of the food chain. 

Permanent fauna live in the estuaries for an entire life cycle. Temporary fauna include 

the juvenile and larval forms of marine organisms such as polychaetes, fish, shrimp, 

bivalves, and crabs. These use estuarine areas as nursery grounds, and are dispersed by 

the currents to different habitats when they reach maturity. 

Recreationally and commercially important species in the estuaries of the Springs 

Coast Basin include striped mullet (Mugil cephalus), red drum (Sciaenops ocellatus),

spotted seatrout (Cynoscion nebulosus), Gulf menhaden (Brevoortia patronus), Atlantic 

croaker (Micropogonias undulatus), sea catfish (Arius felis), gafftopsail catfish (Bagre 

marinus), bay anchovy (Anchoa mitchilli), and striped anchovy (Anchoa hepsetus). Two 

species of sea turtles are occasionally found here: the Atlantic loggerhead (Caretta 

caretta) and Atlantic leatherback (Dermochelys coriacea).

Soft-bottom areas. Subtidal unconsolidated bottom environments such as mud and 

sand form extensive areas of habitat in the Springs Coast Basin. They are mainly found 

between oyster bars and seagrass beds, and at the mouths of rivers. 

These areas contain many different kinds of species, most of which are buried in the 

bottom sediments, or live and feed on the bottom. They include polychaetes, 

oligochaetes, chironomids, amphipods, bivalves, and isopods, as well as starfish, sand 

dollars, blue crabs, spider crabs, benthic fish, and skates and rays. Recreationally and 

commercially important species found include southern flounder (Paralichthys 

lethostigma), northern quahog (Mercenaria mercenaria), sunray venus (Macrocallista 

nimbosa), and blue crab (Callinectes sapidus). 

Seagrass beds. Seagrasses are an extremely important habitat in the nearshore 

coastal waters of the Springs Coast Basin. Five species are found: turtlegrass (Thalassia 

testudinum), manateegrass (Syringodium filiforme), shoalgrass (Halodule wrightii), and 

star grass (Halophila engelmanii) are abundant, while another star grass species, H. 

decipiens, is relatively scarce. The seagrasses form essentially a single bed, extending 

from Florida’s Big Bend area to the open-sand areas along the southernmost reaches of 

the Springs Coast Basin, and covering more than 3,000 square kilometers. They occur in 
174 Water Quality Assessment Report: Springs Coast

an offshore band 10 to 35 kilometers wide between St. Marks and Tarpon Springs. The 

seagrass beds have remained relatively stable over time partly because of the region’s 

extensive, undisturbed tidal marshes and swamps, which filter sediment carried from 

upland areas. Seagrasses are extremely vulnerable to any activities that reduce water 

clarity, such as dredging and filling. 

The distribution and composition of seagrass meadows along the Springs Coast 

depend on salinity levels. Because the major bed-forming species, Thalassia and 

Syringodium, do not grow in low-salinity areas, wigeongrass (Ruppia maritima), and 

brackish-tolerant, freshwater species such as eelgrass (Vallisneria neotropicalis) 

dominate the river mouths. Seagrass levels along the Springs Coast are the highest and 

least patchy for the Weeki Wachee estuary, because of its excellent water clarity and 

relatively smooth bottom. In contrast, seagrass beds in the Crystal River estuary are 

intermixed with shoals and bars. 

Seagrass meadows are highly productive. The numerous types of algae that attach to 

the grasses are an important food source for many herbivorous species. Seagrasses 

harbor a large and diverse number of animals, ranging from tiny, sessile organisms to 

large, commercially important fish such as sea trout. Organisms such as gastropods are 

found on the seagrass blades themselves. Crustaceans are especially abundant in the 

seagrass meadows, both on the blades and in sediments. Fish and scallops are also 

plentiful. Two scallop species—bay scallops (Argopecten irradians) and calico scallops 

(A. gibbus)—are found here. Juvenile and adult blue crabs are also found in large 

numbers. 

Open marine waters. The basin’s marine open water habitat is physically stable 

compared with that of the estuaries. Salinity varies only slightly throughout the year, and 

temperatures do not fluctuate as much or as quickly. Phytoplankton species diversity is 

higher than in the estuaries. 

Many fish use the estuaries as nursery areas and migrate to deeper marine waters as 

adults, eventually to spawn. This habitat includes prized sport and commercial fish such 

as grouper (Mycteroperca spp.), Spanish mackerel (Scomberomorus maculatus), king 

mackerel (S. cavalla), dolphin (Coryphaena hippurus), billfish (Istioophoridae), and 

invertebrates such as the brown shrimp (Penaeus aztecus). Five species of threatened or 

endangered marine turtles are occasionally found in the Springs Coast Basin: the 

Atlantic green turtle (Chelonia mydas mydas), Atlantic hawksbill (Eretmochelys 

imbricata imbricata), Atlantic leatherback (Dermochelys coriacea), Atlantic loggerhead 

(Caretta caretta), and Kemp’s ridley (Lepidochelys kempii). The endangered West 

Indian manatee (Trichechus manatus latirostris) is also found here. 

Terrestrial and Freshwater Communities 

Terrestrial and freshwater communities vary depending on factors such as geology, 

topography, the amount of sunlight available, flooding, fire, and soil chemistry. The 

following describes the major terrestrial and freshwater communities in the Springs Coast 

Basin, as well as their associated species. 
Water Quality Assessment Report: Springs Coast 175

COASTAL STRAND

The coastal areas in the Springs Coast Basin are very flat, sloping imperceptibly 

from low, flat uplands through a level tidal zone and into the very shallow waters of the 

Gulf of Mexico. The coastline is relatively sheltered from wave action and tides, and has 

very small vertical tidal fluctuations. The horizontal tidal fluctuation, however, is large 

because the land surface is so flat. Consequently, a band of salt marsh borders most of 

this low-energy coastline; in inland areas, this gives way to forest. 

Beaches, sand dunes, or coastal strand forests are present in only a few spots—

mostly on offshore islands in the basin. The remnants of ancient sand dunes, which are 

gradually eroding away as the coastline subsides and sea levels rise, supply the sand for 

these beaches. 

Some of the islands support coastal strand forest (maritime hammock), which is 

dominated by sand live oak (Quercus geminata) and live oak (Quercus virginiana), in 

association with cabbage palm (Sabal palmetto), red cedar (Juniperus silicicola), and 

other trees. The majority of coastal live oak, cabbage palm, and red cedar forest is on 

low-lying land subject to flooding, and is classified as hydric hammock. 

Because beaches do not support any living communities of vascular plants, the food 

chain here is based mainly on detritus and sea wrack washed up by storm tides and 

waves. This includes seagrasses and other plant debris, as well as shells, dead fish, 

jellyfish, crabs, and other marine creatures. Insects, amphipods, ghost crabs, fiddler 

crabs, seagulls, and other species feed on the detritus. In turn, shorebirds such as gulls 

and sandpipers feed on the insects, amphipods, and crabs. 

SCRUB

A small but ecologically significant scrub area is present in southern Pasco County, 

in the Middle Coastal Planning Unit. 

Scrub is almost completely restricted to Florida, and many scrub species are 

endemic—that is, they occur only on the Florida peninsula in this habitat. It is, on 

average, the most xeric (dry and hot) of Florida’s communities, and is adapted to natural 

fires. These burn the vegetation periodically (every 10 to 50 years); plants resprout from 

their base or roots. Scrub occurs only on well-drained sand with a low nutrient content. 

Scrub vegetation is almost entirely evergreen. It consists of a dense growth of 

evergreen shrubs and small trees without much herbaceous ground cover. It is often 

fairly uniform in density from the ground to the top of the canopy, except for mature sand 

pine scrub, in which the sand pines form a canopy above the rest of the vegetation. 

In addition to sand pine, scrub plant speciesin the basin include the long-spurred 

mint (Dicerandra cornutissima), scrub pawpaw (Asimina obovata), Florida rosemary 

(Ceratiola ericoides), garbaria (Garbaria heterophylla), palafoxia (Palafoxia feayi),

scrub palmetto (Sabal etonia), and silkbay (Persea humilis). 

Animal species in the basom, some of which are endemic to scrub, include the scrub 

jay (Aphelocoma coerulescens), short-tailed snake (Stilosoma extenuatum), worm lizard 

(Rhineura floridana), peninsula mole skink (Eumeces egregious onocrepis), central 

Florida crowned snake (Tantilla relicta neilli), Florida black bear (Ursus americanus 

floridanus), raccoon (Procyon lotor), white-tailed deer (Odocoileus virginianus), wild 
176 Water Quality Assessment Report: Springs Coast

hog (Sus scrofa), gray squirrel (Sciurus carolinensis), Sherman’s fox squirrel (Sciurus 

niger shermani), and wild turkey (Meleagris gallopavo). Insects include the pushup 

beetle (Peltotrupes spp.), numerous grasshopper species, and the Florida harvester ant 

(Pogonomyrmex badius).

HIGH PINE FOREST (SANDHILL) 

Most of the well-drained uplands in the Springs Coast Basin were originally open 

forests of longleaf pine (Pinus palustris), with a scattered subcanopy of deciduous oaks 

and a ground cover of wiregrass (Aristida stricta), other grasses, and broad-leaved herbs. 

Several hundred thousand acres of younger, denser forest of this type remain, mostly in 

the Withlacoochee State Forest and elsewhere on the Brooksville Ridge in central Citrus 

and Hernando Counties. However, there are no virgin sandhill tracts left in Florida. 

Fire plays a dominant role in the sandhill community. Historically, it burns mostly 

in summer every two to three years. When fire is suppressed, the community is replaced 

within a century by a xeric (dry) to mesic (moist) hammock of low diversity. 

Most sandhill species are adapted to—and in fact depend on—frequent, low-intensity 

ground fires. Grasses, herbs, and small woody plants resprout from their bases or roots, 

while longleaf pine and hardwoods such as turkey oak (Quercus laevis), southern red oak 

(Quercus falcata), and mockernut hickory (Carya tomentosa) have thick bark, stems, 

branches, and buds to withstand the effects of fire. Longleaf pine cannot reproduce 

unless fires thin out the understory vegetation and leaf litter, allowing the seedlings to 

take hold. Other plant species found here include dwarf blueberry (Vaccinium 

myrsinites), gopher apple (Licania michauxii), and showy pawpaw (Asimina incarna).

The high pine community supports numerous animal species, many of which are 

declining. Of these, the gopher tortoise (Gopherus polyphemus) is perhaps the most 

important. The tortoise’s 15- to 20-foot-long burrows are home to nearly 40 additional 

species, including the Florida mouse (Podomys floridanus), gray fox (Urocyon 

cinereoargenteus), indigo snake (Drymarchon corais), coachwhip (Masticophis 

flagellum), eastern diamondback rattlesnake (Crotalus adamanteus), and gopher frog 

(Rana capito). 

Other sandhill species in the basin include the red-cockaded woodpecker 

(Dendrocopos borealis), southeastern kestrel (Falco sparverius), Sherman’s fox squirrel 

(Sciurus niger shermani), common ground dove (Columbina passerina), loggerhead 

shrike (Lanius ludovicianus), Bachman’s sparrow (Aimophila aestivalis), northern 

bobwhite (Colinus virginianus), eastern bluebird (Sialia sialis), tufted titmouse (Parus 

bicolor), great crested flycatcher (Myiarchus crinitus), and screech owl (Otus asio).

Sandhills dominated by turkey oak (Quercus laevis) are common today on the 

Brooksville Ridge. Most of the original longleaf pines growing in these areas were 

harvested for use in the rosin industry. 

PINE FLATWOODS

The pine flatwoods community is found in southern and central Pasco County and a 

very small area in south-central Hernando County, in the Middle Coastal Planning Unit. 

It occurs on very flat, poorly drained land where the soil is sandy, acidic, and low in 
Water Quality Assessment Report: Springs Coast 177

nutrients. A clay hardpan layer usually underlies the water table, which ranges from 1 to 

4 feet below the surface. During wet periods, the soils may remain saturated with water 

for several months. Conversely, during droughts, the water table may lie below plant 

root zones. Both of these conditions, in addition to the lack of nutrients and soil acidity, 

severely stress plant and animal species and restrict species composition. 

Like the high pine forest, fire plays a similar role, and some of the dominant plants 

(such as longleaf pine and wiregrass) are the same. However, the shrub understory burns 

less frequently (every two to five years, with considerable variation) but more intensely. 

This community has two layers: a tall forest of pine with a second layer of evergreen 

shrubs, mostly saw palmetto (Serenoa repens), gallberry (Ilex glabra), and fetterbush 

(Lyonia lucida). Diverse grasses and wildflowers are also present. 

Animal species include the pine woods tree frog (Hyla femoralis), southern black 

racer (Coluber constrictor priapus), eastern diamondback rattlesnake (Crotalus 

adamanteus), eastern indigo snake (Drymarchon corais couperi), pine warbler 

(Dendroica pinus), brown-headed nuthatch (Sitta pusilla), summer tanager (Piranga 

rubra), blue-gray gnatcatcher (Polioptila caerulea), eastern wood-pewee (Contopus 

virens), northern bobwhite (Colinus virginianus), Bachman’s sparrow (Aimophila 

aestivalis), rufous-sided towhee (Pipilo erythrophthalmus), white-eyed vireo (Vireo 

griseus), Carolina wren (Thryothorus ludovicianus), white-tailed deer (Odocoileus 

virginianus), wild hog (Sus scrofa), and hispid cotton rat (Sigmodon hispidus). 

HAMMOCKS

Hammocks are found in a number of areas in the Springs Coast Basin, mainly in 

Pasco, Hernando, and Citrus Counties in a broad north-south belt that lies just inland 

from the coast. Other areas are located in south-central Hernando County and eastern 

Citrus, Hernando, and Pasco Counties. These hammocks are particularly important to the 

fauna of much of the eastern United States, because they support very large populations 

of overwintering songbirds and provide important habitat for migrants that winter farther 

south. 

Scattered in a few spots throughout Florida’s original vast pine forests, these dense 

hardwood forests develop in places that are protected to some degree from wildfire by 

bodies of water or swamps. While most hammocks occur in flat areas, some are found in 

slopes along rivers and their tributaries, and on the sides of sinkholes. Hammocks grow 

in a wide variety of soils, but they are generally found in areas containing relatively 

fertile soil, with either clay or limerock near the surface. There are three main types of 

hammocks: xeric (dry), mesic (moist), and hydric (wet). 

The dominant trees are usually a mixture of oaks (Quercus spp.), other hardwoods, 

understory trees, and shrubs; the individual species vary depending on the type of 

hammock and its distance from the coast.

The most distinctive feature of hammocks is the invertebrate fauna of the forest 

floor; these species include snails, earthworms, millipedes, isopods, springtails, 

harvestmen, mites, beetles, orthopterans, dipterans, and hemipterans. In turn these 

support a diversity of spiders and other predatory insects, amphibians, reptiles, birds, and 

mammals. 
178 Water Quality Assessment Report: Springs Coast

SINKHOLES AND TERRESTRIAL CAVES

Caves are common in the Springs Coast Basin, particularly in central Citrus and 

Hernando Counties. Inside the caves, algae and fungi predominate, but there are no 

vascular plants. However, there is often an interesting community of calcareous (mesic) 

hammock plants in sinkholes or on the rock outcrops associated with the caves. Many 

fern species are largely confined to sinkholes with limerock outcrops. Central Citrus and 

Hernando Counties contain the best-known populations of some of these plants. They 

include two species of maidenhair fern (Adiantum tenerum and A. capillus-veneris), two 

species of brake fern (Pteris vittata and P. cretica), a number of species of spleenwort 

(Asplenium heterochroum, A. resiliens, A. cristatum, A. pumilum, A. verecundum, A. 

auritum, and A. subtile), southern lip fern (Cheilanthes microphylla), sinkhole fern 

(Blechnum occidentale), and several species of wood fern (Thelypteris spp.). Other 

species include mosses and liverworts. Twenty-four species of pteridophytes (ferns and 

fern allies) were recorded from Pineola Grotto in Citrus County. 

There is less animal life in the caves than in surface habitats. Species found in the 

caves include deer mice (Peromyscus spp.), eastern woodrats (Neotoma floridana), rat 

snakes (Elaphe spp.), and salamanders. Their main habitat value is for bats. Breeding 

colonies of the southeastern myotis bat (Myotis austroriparius), sometimes numbering in 

the thousands, occupy some of the caves during the summer. Several other bat species 

also use the caves. 

The bat guano in the caves serves as the base of the food chain for cave 

invertebrates. These include two spiders (Gaucelmus augustinus and Nesticus pallidus),

two springtails (Isotoma notabilis and Tomocerus dubius), and a cave cricket 

(Ceuthopilus latibuli). The caves also contain mites (Acarina), harvestmen (Phalangida),

and other invertebrates—including aquatic invertebrates if water is present. 

BAYHEAD

Bayheads in the Springs Coast region occur mostly as small, scattered patches of a 

few acres to perhaps 100 acres. This community is generally defined as a wetland forest 

dominated by any one or a combination of 3 species of broad-leaved evergreen trees, 

known as bay trees. Swamp tupelo (Nyssa sylvatica var. biflora), a deciduous tree, is 

also generally codominant. There is usually a moderately dense shrub layer dominated 

by broad-leaved, evergreen species. Ferns are often abundant in the ground cover. 

Soils are acidic and usually made up of peat or organic muck, underlain by sand. 

Bayheads may either be on seepage slopes or on peat bogs with good drainage. Although 

found in moist areas, they are usually not subject to flooding. They are exposed to fire 

but, unlike pine communities, are neither adapted to fire nor dependent on it. 

Plant species found here include loblolly bay (Gordonia lasianthus), sweet bay 

(Magnolia virginiana), and swamp bay (Persea palustris). Animal species include 

numerous birds, amphibians, reptiles, and black bears. 

MIXED SWAMP

There are large areas of mixed swamp all along the Gulf Coast, with one of the 

largest and best examples in and around the Chassahowitzka National Wildlife Refuge. 
Water Quality Assessment Report: Springs Coast 179

Mixed swamps generally occur as strands or sloughs, or as the deep-water part of the 

floodplain forests alongside rivers, creeks, or lakes. These wetlands are often flooded for 

months at a time. They are generally tall, dense forests, with an open, deeply shaded 

understory and sparse ground cover. However, some of the most deeply flooded swamps 

and most swamps right on the coast have an open canopy of shorter trees and much more 

shrub and groundcover vegetation. 

Soils in mixed swamps are usually sand or clay over limerock, with varying amounts 

of muck on the surface. Because the swamps are generally connected hydrologically to 

an established drainage system, the water is generally flowing except during very low 

water. The soil never dries out much below the surface. Mixed swamps are flooded a 

little more than half the time. They rarely, if ever, burn, except for individual trees struck 

by lightning. 

Mixed swamps are very fertile and productive communities, but they are not 

especially diverse. Tree species such as green ash (Fraxinus pennsylvanica), pumpkin 

ash (Fraxinus profunda), swamp tupelo (Nyssa sylvatica), bald cypress (Taxodium 

distichum), and red maple (Acer rubrum) are present. Other trees are mixed in to some 

degree, usually in the shallower areas or edges of the swamp. These include cabbage 

palm (Sabal palmetto), swamp laurel oak (Quercus laurifolia), sweet bay (Magnolia 

virginiana), sweet gum (Liquidambar styraciflua), American hornbeam (Carpinus 

caroliniana), and Florida elm (Ulmus Americana var. floridana). Buttonbush 

(Cephalanthus occidentalis) is often the only shrub, except in the more open forests, 

where wax myrtle (Myrica cerifera) is also common. 

A combination of flooding and shade restricts the diversity of herbaceous plants. 

The more open, deep-muck swamps may contain an abundance of bamboo vine (Smilax 

laurifolia). Densely forested mixed swamps may have very few herbaceous plants. 

The major swamp habitats are the crowns of the tall trees, the hollow trunks and 

branches of older trees, the muck, and the water. Animal species include mud-dwelling 

earthworms, several kinds of crayfish and shrimp, several kinds of snails—including the 

Florida apple snail (Pomacea paludosa), which is the primary food source for the limpkin 

(Aramus guarauna)—and numerous insects and their larvae. The cavities in tree trunks 

are especially important, because there is little shelter on the ground. Swamp-dwelling 

birds requiring cavities for nesting include the wood duck (Aix sponsa), barred owl (Strix 

varia), great crested flycatcher (Myiarchus crinitus), Carolina chickadee (Parus 

carolinensis), tufted titmouse (P. bicolor), and prothonotary warbler (Protonotaria 

citrea). Other tree-dwelling species include the gray squirrel (Sciurus carolinensis),

flying squirrel (Glaucomys volans), eastern woodrat (Neotoma floridana), cotton mouse 

(Peromyscus gossypinus), Virginia opossum (Didelphis virginiana), raccoon (Procyon 

lotor), and various snakes and lizards. 

CYPRESS DOME

In the Springs Coast Basin, cypress domes occur as isolated swamps in depressions 

scattered throughout the pine flatwoods community in south-central Hernando County 

and central Pasco County. Most of these domes range between 1 and 100 acres in size. 

The smaller ones are mostly round to oval and are often dome-shaped when viewed from 
180 Water Quality Assessment Report: Springs Coast

the side, since the tallest trees grow in the center of the swamp. Some larger domes are 

open in the middle and contain either an open pond or a small marsh. 

Pond cypress (Taxodium ascendens) are the predominant tree species in the domes. 

Very dense shrubs usually form a border around the edge that supports much of the plant 

and animal diversity, and helps to maintain a moist microclimate inside the dome. If 

shrubs or ground cover are present in the interior, they usually comprise fetterbush 

(Lyonia lucida) and Virginia chain fern (Woodwardia virginica). Other hardwoods may 

also be present around the edge. 

Soils are nutrient poor and more acidic than in other kinds of swamps. Cypress 

domes have clay hardpans at varying depths, so that they are rather like large, shallow 

saucers that hold water. Some organic topsoil or sediment is usually present on the 

surface. 

The domes are isolated hydrologically except at high water, when they overflow 

through poorly defined channels from one dome to the next. As with other swamps, 

many domes lose their surface water almost every year during the dry season. During 

severe droughts, however, the water stored in the soil may also disappear, subjecting the 

vegetation to severe drought stress. Cypress domes are a fire-adapted community; the 

bark of pond cypress is much thicker than that of other cypress species, allowing it to 

withstand fires. 

The cypress domes provide valuable habitat for a number of reptile and amphibian 

species, but have few mammals and no unique bird species. However, they add an 

important element of diversity to the flatwoods areas, support a higher density and 

diversity of animals than the surrounding flatwoods, and are important as a refuge for the 

flatwoods fauna when the pine forests are harvested. The dense thicket at the edge is 

especially valuable habitat, containing much higher densities and diversity of reptiles, 

amphibians, and birds than either adjacent community. Cypress domes, especially the 

edge thickets, are an important habitat for white-tailed deer. Other animal species found 

here include the chicken turtle (Deirochelys reticularia), glossy crayfish snake (Regina 

rigida), and dwarf siren (Pseudobranchus striatus). 

FRESHWATER MARSHES AND PRAIRIES

The Springs Coast Basin contains numerous freshwater marshes and prairies 

scattered throughout the pine flatwoods areas, or in low spots on the Brooksville Ridge. 

These treeless wetlands vary in size from less than an acre to several hundred acres. 

They occur in areas of permanent shallow water, around lakes, or in areas that flood or 

burn frequently enough to prevent woody plants from invading. The term wet prairie is 

used in central and south Florida for very shallow marshes in the pine flatwoods that are 

often dry and burn frequently. Soils are made up of sand over limerock—or, in the 

flatwoods, of varying amounts of organic muck over sand, with a clay layer beneath. 

A single species of tall grass, sedge, or other herb often dominates marshes and wet 

prairies. The predominance of a particular species often changes with water depth, 

sometimes producing a series of bands of different vegetation from the edge to the 

deepest area. In general, the emergent plants are more common in areas with shallower 
Water Quality Assessment Report: Springs Coast 181

water, and the floating-leaved and submerged plants are more common in deeper water. 

Algae comprise the base of the food chain in the marshes and prairies. 

Many of the basin’s marshes contain nearly pure stands of maidencane (Panicum 

hemitomon). Other species that may be present—depending on the soil, water depth, and 

hydroperiod—are pickerelweed (Pontederia cordata), bladderwort (Utricularia spp.),

and bluestem (Andropogon spp.). Cordgrass (Spartina bakeri) and swamp hibiscus

(Hibiscus grandiflorus) are found in mildly brackish areas near the coast. Cattail (Typha 

spp.) marsh grows in areas of high fertility, often replacing other forms of marsh in the 

presence of nutrients from fertilizers or sewage effluent. 

Some marsh vegetation on the edges of lakes is highly desirable. The deep water 

parts of the marsh often contain patches of white water lilies (Nymphaea odorata),

spatterdock (Nuphar luteum), or thin stands of maidencane (Panicum hemitomon). These 

provide good habitat for large fish, such as largemouth bass (Micropterus salmoides) and 

bream (Lepomis macrochirus). The denser marsh vegetation in shallower waters harbors 

numerous smaller fish, providing a nursery area and a habitat that supports an important 

part of the food chain. Marshes also support many other animals, help remove nutrients 

from the lake, and trap sediments washed from the shore into the lake. 

Marshes and prairies are habitat for a number of broadly adapted aquatic species and 

a few terrestrial species. Some animals are specifically adapted to this habitat. Species 

that use marshes include the hispid cotton rat (Sigmodon hispidus), red-winged blackbird 

(Agelaius phoeniceus), peninsula newt (Notophthalmus viridescens piaropicola), several 

kinds of frogs, and a number of small fish species. Insects, crayfish, snails, and other 

invertebrates are also quite abundant, providing a good food source for wading birds, 

raptors, and other predators. Marshes that go dry periodically are particularly important 

feeding habitat for wood storks (Mycteria americana). Other species that use marshes 

include the sandhill crane (Grus canadensis), American bittern (Botaurus lentiginosus),

king rail (Rallus elegans), Florida green water snake (Nerodia floridana), and roundtailed muskrat (Neofiber alleni). 

PONDS

Ponds are small bodies of open, nonflowing water. There are thousands of ponds of 

5 acres or less in the Springs Coast Basin, and dozens of larger ones. Most were formed 

by the collapse of solution caves in the underground limestone aquifer, while others are 

shallow depressions that were once part of ancient seas. They are diverse in their sizes, 

depths, and locations. 

While many ponds are permanent, some are ephemeral, drying out completely every 

few years. All ponds are temporary, however, since they eventually fill up with 

sediment. Pond ecology is influenced by the surrounding upland soils and biological 

communities. Another important factor is whether a pond is isolated or part of a drainage 

system. The most important factor determining the diversity and species inhabiting a 

pond is whether it is permanent. 

The plants around the edges of ponds are mostly swamp, marsh, and wet prairie 

plants. Some of the submerged marsh plants grow in the open water areas. Pond species 

include duckweed (Lemna spp. and Spirodela spp.), water spangles (Salvinia minima),
182 Water Quality Assessment Report: Springs Coast

mosquito fern (Azolla caroliniana), and several kinds of Sagittaria. However, algae are 

the most important plants in terms of importance to wildlife. 

No other habitat has such a high value per acre, and the habitat value of ponds 

increases with their isolation and separation from other wetlands. A very significant part 

of the animal species of an area larger than 2,000 acres may depend on less than 1 acre of 

ephemeral, isolated pond. A single, isolated pond may also have great importance as a 

source of drinking water for some animals, such as doves (Columbina passerina and 

Zenaida macroura) and nighthawks (Chordeiles minor). Ponds are breeding sites for a 

number of insects, amphibians, and birds, including toads (Bufo spp. and Scaphiopus 

holbrookii), tree frogs (Hyla spp.), gopher frogs (Rana capito), and dragonflies. 

LAKES

The Springs Coast Basin contains several hundred scattered lakes with areas of 5 to 

1,000 acres. Like ponds, these large, permanently flooded bodies of nonflowing, open 

water were formed through the collapse of solution caves in the limestone aquifer, or are 

shallow depressions that once formed on an ancient sea floor. Factors influencing the 

ecology of lakes include size, depth, type of bottom, water quality, water level 

fluctuation, water inflow and outflow, and adjacent wetland and upland ecosystems. 

The swamps and marshes that are often found on the edges of a lake’s open water 

area are ecologically important. They are generally more biologically productive than 

open water, supplying small fish, insects, crayfish, amphibians, and other small animals 

that provide an abundant food source for the larger fish and predators in the open water. 

Wetlands also serve as nursery areas for some open water species, remove excess 

nutrients and other pollutants before they enter the lake, and buffer wave action. 

Marsh and swamp plant species, discussed earlier, are commonly found on the 

margins of lakes. Plants in the open water areas are dominated by single-celled algae, 

mostly diatoms and green algae. 

Animal species found in or near lakes include numerous birds, fish, reptiles, and 

amphibians. 

SPRINGS, SPRING RUNS, AND SPRING-FED RIVERS

Coastal areas of the Springs Coast Basin contain many springs. These result from 

rain falling on inland areas; the water drains underground through sinkholes and other 

channels and fissures in the porous limestone rock, reemerging at the land surface. The 

largest springs in the basin are Crystal River, Chassahowitzka, Homosassa, and Weeki 

Wachee, which form the headwaters of large coastal rivers that flow to the Gulf of 

Mexico. Many smaller springs are also present. 

Springs provide permanent base flow to rivers and streams in the basin. The water 

temperature remains nearly constant year round, and the water itself is very clear, 

nonacidic, and high in dissolved solids such as calcium carbonate. 

Spring-connected streams have a diverse and productive year-round aquatic plant 

community. In addition, because they never stop flowing, they provide important refuges 

during droughts for aquatic animal species. 
Water Quality Assessment Report: Springs Coast 183

The plant species along spring runs and spring-fed rivers usually consist of mixed 

swamp on shore and freshwater marsh in some scattered, shallow water areas. In some 

places, hammock forests reach the stream banks. The submerged plants on the stream 

bottom, however, are markedly different. There are abundant quantities of eelgrass 

(Vallisneria americana) and arrowhead (Sagittaria). Of equal or greater importance are 

the diatoms and filamentous algae that are attached to these plants and to everything else 

on the stream. The submerged plants and algae provide dense cover and a productive 

foundation for the food chain. 

Large numbers of aquatic snails support predators such as the loggerhead musk turtle 

(Sternotherus minor minor) and limpkin (Aramus guarauna). The latter feeds mainly on 

the Florida apple snail (Pomacea paludosa). Other species include marine fish and the 

endangered West Indian manatee (Trichechus manatus latirostris).

AQUATIC CAVES

The thick bed of limerock under the Springs Coast Basin contains many cracks, 

joints, fissures, and caves filled with water. Underwater or aquatic caves formed when 

the slightly acidic water dissolved larger passageways over thousands of years. The 

caves are often interconnected, forming a complex, extensive maze of passageways 

beneath much of the basin. There are distinct layers in the limerock, each with its own 

caves, and the different layers are interconnected by occasional vertical shafts. The 

Crystal River Formation in the Upper Eocene Formation contains the most caverns. 

The water in the caves is generally very clear, with a constant temperature, relatively 

neutral pH, and high levels of dissolved calcium carbonate. Considerable currents may 

be present. 

A unique and specialized group of animal species has evolved to take advantage of 

this unique habitat. The region may have more species of blind aquatic cave-dwelling 

animals than any other region in the world. Invertebrates are predominant. Species 

found here include McLane’s cave crayfish (Troglocambarus maclanei), pallid cave 

crayfish (Procambarus pallidus), light-fleeing cave crayfish (P. lucifugus), and 

Leitheuser’s cave crayfish (P. leitheuseri). At least two amphipods, two isopods, and one 

shrimp are present. The caves also provide important habitat for the American eel 

(Anguilla rostrata) and redeye chub (Notropis harperi). 

Land Cover 

The Springs Coast Basin is noteworthy for the extent and diversity of its remaining 

natural lands. Table B.1 provides comparisons of current and historical acreages for the 

major types of land cover in the basin. Table B.2 lists the major conservation areas, 

including their total acreages, locations, and managing entities. 

Of the 21 most-endangered ecosystems in the United States, 6 are found in the basin. 

Xeric uplands originally accounted for about 40 percent of the basin’s total land area. 

The longleaf pine–turkey oak sandhill community has been reduced to only 15 percent 

of its historical range on the Gulf Coastal Plain, while Florida scrub has been eliminated 

from 65 to 75 percent of its original statewide range. Sandhill vegetation was the 
184 Water Quality Assessment Report: Springs Coast

hallmark natural community of the Brooksville Ridge. It is characteristic of the deep, 

well-drained sands that distinguish the ridge and impart the very high ground water 

recharge rates. The permeability of these sands also makes the local ground water highly 

susceptible to contamination. 

The coniferous (longleaf pine) and broadleaf (hammock) forests of the southeastern 

United States are among the most biologically valuable on earth. They are also highly 

endangered. Of all the communities in the basin, pine flatwoods has been most severely 

reduced by development. Of this community’s historical coverage, only 16,700 acres 

remain—or about 20 percent. The upland hardwood community that distinguishes the 

biologically rich and culturally significant Annutteliga Hammock has been reduced to 50 

percent of its historical coverage. Most of the original expanse of hardwood forest 

associated with the Annutteliga system has been lost to development and limerock 

mining. Unfortunately, much of the remaining “hammock” consists of small fragments 

that retain little of their original habitat value. 

Southern forested wetlands are represented by a spectacular, unbroken expanse of 

hydric hammock along the basin’s Gulf Coast shoreline. Although estimates of wetland 

area for the Springs Coast Basin vary, wetlands account generally for around 25 percent 

of the basin. Wetlands have fared much better than uplands, because the majority of 

wetland acreage in the basin occurs as large, continuous systems aligned along the coast. 

These have not been as susceptible to destruction through land development as the 

relatively small, isolated wetlands that characterize large portions of other basins in the 

state. 

Cave and karst systems consist of a unique network of first-magnitude springs and 

spring-fed rivers. Another land cover type, coastal communities, comprises one of the 

most pristine and productive estuarine systems in Florida. 

Patterns of public land ownership can help to explain the effective protection of 

wetlands, relative to uplands, in the Springs Coast Basin. Of the 194,500 acres dedicated 

to conservation, approximately 141,350 acres are sandwiched between the Gulf of 

Mexico and U.S. Highway 19. This amounts to 73 percent of conservation lands in the 

basin. Three of the four large conservation tracts located inland of the coast (Citrus, 

Serenova, and Starkey) lie on the basin’s boundary, with large portions extending into 

adjoining basins. 

Conservation Priorities 

A SWFWMD study of the remaining natural lands in the basin, using a geographic 

information system (GIS) analysis, assessed the relative importance of proposed 

acquisitions and identified other potential sites. 

The highest priority for habitat protection is the coastal lands at the northern end of 

the basin (extending from the Homosassa River northward to the basin boundary). These 

connect the basin’s coastal systems with the Big Bend coastline, creating a continuous 

swath of core habitat covering nearly 1.2 million acres. Although the vast majority of the 

core area lies outside the SWFWMD’s boundaries, maintaining connectivity within this 

vast area would help to ensure the long-term integrity of the basin’s network of 

conservation lands. 
Water Quality Assessment Report: Springs Coast 185

The second priority is addressing the gap in public ownership north of the Weeki 

Wachee River and maintaining connectivity with the Citrus Tract by protecting the 

Annutteliga Hammock. The latter would also protect the remaining remnants of the 

hammock vegetation that once distinguished this region of Florida. 

The protection of these tracts would preserve the overall size of the protected core 

habitat along the coastline by maintaining the existing contiguity in that system. It would 

also maintain the existing connectivity between the coastal core and the core habitats 

provided by the Citrus Tract (the Withlacoochee State Forest) and the Big Bend coastline 

north of the basin, and prevent the loss of valuable coastal habitat at the southern end of 

the Weekiwachee Preserve. The latter provides habitat for a population of the threatened 

Florida black bear and other imperiled species, and also helps to buffer the Weekiwachee 

Preserve from the intensive development that has consumed the coastal area in the 

southern reaches of the basin. 

Another ecologically important area with a high priority for protection is westcentral Pasco County, east of Port Richey from the Starkey Wilderness Preserve toward 

the Weekiwachee Preserve.

cover category most likely to occur on that soil type. Disturbances associated with mining activities and 

other development that predated the soil surveys precluded the inference of historical land cover over 

portions of the basin; this accounts for the acreage listed as disturbed under historical coverage.

Appendix C: Information on Reasonable Assurance 

TO: Interested Parties 

FROM: Mimi Drew, Director 

 Division of Water Facilities 

DATE: September 2002 

SUBJECT: Guidance for Development of Documentation To Provide 

Reasonable Assurance that Proposed Pollution Control Mechanisms Will Result in 

the Restoration of Designated Uses in Impaired Waters 

The purpose of this memo is to describe the types of information that should be 

considered, and subsequently documented, when evaluating whether there is sufficient 

reasonable assurance that: 

Proposed pollution control mechanisms (typically described in watershed 

management or restoration plans) addressing impaired waters will result in the 

attainment of applicable water quality standards (designated uses) at a clearly 

defined point in the future, and 

Reasonable progress towards restoration of designated uses will be made by the time 

the next 303(d) list of impaired waters is due to be submitted to the EPA. 

There are many site-specific issues related to determining whether reasonable 

assurance has been provided. Accordingly, this document describes the elements or 

issues that should be considered when evaluating a submittal or when documenting the 

basis for the Department’s decision, rather than attempting to establish specific criteria on 

what constitutes reasonable assurance. 

It should be noted that the term “reasonable assurance” is used throughout many 

Department programs and rules, and this guidance specifically addresses the issues 

related to the “reasonable assurance” provided by proposed pollution control 

mechanisms. This guidance should not be used to evaluate the meaning of reasonable 

assurance in other contexts, particularly in permitting decisions. 

Background 

The Impaired Surface Waters Rule (IWR), Rule 62-303, F.A.C. (Identification of 

Impaired Surface Waters), establishes a formal mechanism for identifying surface waters 

in Florida that are impaired (do not meet applicable water quality standards) by 

pollutants. Most waters that are verified as being impaired by a pollutant will be listed on 
188 Water Quality Assessment Report: Springs Coast

the state’s 303(d) list pursuant to the Florida Watershed Restoration Act (FWRA) and 

Section 303(d) of the Clean Water Act. Once listed, Total Maximum Daily Loads 

(TMDLs) will be developed for the pollutants causing the impairment of the listed 

waters. However, as required by the FWRA, the Department will evaluate whether 

existing or proposed pollution control mechanisms will effectively address the 

impairment before placing a water on the state’s Verified List. If the Department can 

document there is reasonable assurance that the impairment will be effectively addressed 

by the control measure, then the water will not be listed on the final Verified List (other 

impaired waters that will not be listed include waters with TMDLs and waters impaired 

by pollution). 

Current Rule Text Relating to Evaluation of Pollution Control Mechanisms 

The rule text addressing the evaluation of proposed pollution control mechanisms is 

as follows: 

Section 62-303.600, Evaluation of Pollution Control Mechanisms 

Upon determining that a waterbody is impaired, the Department shall evaluate 

whether existing or proposed technology-based effluent limitations and other 

pollution control programs under local, state, or federal authority are sufficient to 

result in the attainment of applicable water quality standards. 

If, as a result of the factors set forth in (1), the waterbody segment is expected to 

attain water quality standards in the future and is expected to make reasonable 

progress towards attainment of water quality standards by the time the next 303(d) 

list is scheduled to be submitted to EPA, the segment shall not be listed on the 

Verified List. The Department shall document the basis for its decision, noting 

any proposed pollution control mechanisms and expected improvements in water 

quality that provide reasonable assurance that the waterbody segment will attain 

applicable water quality standards. 

Responsible Parties for Reasonable Assurance Demonstration 

It is ultimately the Department’s responsibility to assure adequate documentation in 

the administrative record whenever the Department decides to not list an impaired 

waterbody segment for a given pollutant. This documentation will be very important 

because the Verified Lists will be adopted by Order of the Secretary and third parties will 

be provided an opportunity to challenge, via an administrative hearing, all listing 

decisions (both those listing a water and those to not list a water for a given pollutant). 

However, the Department expects that local stakeholders will often offer to prepare the 

necessary documentation to demonstrate reasonable assurance that proposed control 

mechanisms will restore a given waterbody. The Department will provide guidance to 

stakeholders on what information is needed and how it should be submitted. 
Water Quality Assessment Report: Springs Coast 189

Time Frame for Development of Documentation 

The Department plans to prepare basin-specific Verified Lists as part of its 

watershed management cycle, which rotates through all of the state’s basins over a fiveyear, five-phased cycle1

. During the first phase of the cycle, the Department will assess 

water quality in the basin and prepare a draft Planning List of potentially impaired 

waters. The Department and interested parties will then have approximately one year 

(Phase 2) to monitor waters on the planning list and prepare documentation, as 

appropriate, to provide reasonable assurance that impaired waters will be restored. The 

Department will review submittals from interested parties during Phase 2, before 

adopting the Verified List for the basin containing the waterbody segment in question. 

What It Means To Be Under Local, State, or Federal Authority 

Both the FWRA and the IWR require that the pollution control programs under 

consideration be “under local, state, or federal authority.” A pollution control program 

will be considered "under local, state, or federal authority" if the program is subject to or 

required by a local ordinance, state statute or rule, or federal statute or regulation. 

Programs will also be considered under local, state, or federal authority if they are 

subject to a written agreement, signed by both local stakeholders and at least one 

governmental entity, that includes measurable goals, performance criteria, benchmarks, 

and back-up corrective actions to assure the further progress of the program. It is 

important to note that these written agreements do not need to be enforceable for 

nonregulated nonpoint sources. 

Many nonpoint sources are currently outside of the regulatory programs of EPA, the 

Department, and the water management districts, and reductions at these nonpoint 

sources will be voluntary. In fact, pollution control mechanisms for these nonpoint 

sources would be voluntary even if a TMDL were developed. As such, these agreements 

may provide the same level of reasonable assurance that can be provided for a TMDL 

implementation plan as long as they maintain the Department’s enforcement capability 

over all point sources involved. 

Time Frame for Attaining Water Quality Standards 

The FWRA and the IWR do not establish a specific time limit by which waters must 

attain applicable water quality standards or designated uses. However, the pollution 

control mechanisms or watershed restoration plan must provide reasonable assurance that 

designated uses will be met at some time in the future. As such, the documentation 

submitted to the Department must provide a specific date by which time designated uses 

are expected to be restored. In cases where designated uses will not be met for many 

years, the documentation should also provide justification as to why the specified time is 

needed to restore designated uses.

 Federal regulations currently call for state 303(d) lists every two years, but Florida plans to submit annual updates 

based on the basin-specific Verified Lists. 
190 Water Quality Assessment Report: Springs Coast

Parameter-Specific Nature of Demonstration 

For the Department not to place an impaired waterbody segment on the Verified List, 

reasonable assurance must be provided for each pollutant that has been documented to be 

causing impairment of the waterbody segment. However, some entities, including the 

Department, may want to provide reasonable assurance addressing only selected 

pollutants, which could result in the Department not listing the waterbody segment for 

those pollutants, but still listing it for others. In this event, TMDLs will only be 

developed for the remaining listed pollutants. 

Information To Consider and Document when Assessing Reasonable 

Assurance in the IWR 

To provide reasonable assurance that existing or proposed pollution control 

mechanisms will restore designated uses, the following information should be evaluated 

and documented for the Administrative Record: 

A Description of the Impaired Water—name of the water listed on the Verified 

List, the location of the waterbody and watershed, the watershed/8-digit 

cataloging unit code, the NHD identifier (when they become available), the type 

(lake, stream, or estuary) of water, the water use classification, the designated use 

not being attained, the length (miles) or area (acres) of impaired area, the 

pollutant(s) of concern (those identified as causing or contributing to the 

impairment), and the suspected or documented source(s) of the pollutant(s) of 

concern. 

A Description of the Water Quality or Aquatic Ecological Goals—a description of 

the water quality–based targets or aquatic ecological goals (both interim and final) 

that have been established for the pollutant(s) of concern, the averaging period for 

any numeric water quality goals, a discussion of how these goals will result in the 

restoration of the waterbody’s impaired designated uses, a schedule indicating 

when interim and final targets are expected to be met, and a description of 

procedures (with thresholds) to determine whether additional (backup) corrective 

actions are needed. 

A Description of the Proposed Management Actions To Be Undertaken—names 

of the responsible participating entities (government, private, others), a summary 

and list of existing or proposed management activities designed to restore water 

quality, the geographic scope of any proposed management activities, 

documentation of the estimated pollutant load reduction and other benefits 

anticipated from implementation of individual management actions, copies of 

written agreements committing participants to the management actions, a 

discussion on how future growth and new sources will be addressed, confirmed 

sources of funding, an implementation schedule (including interim milestones and 
Water Quality Assessment Report: Springs Coast 191

the date by which designated uses will be restored), and any enforcement 

programs or local ordinances, if the management strategy is not voluntary. 

A Description of Procedures for Monitoring and Reporting Results—a 

description of the water quality monitoring program to be implemented (including 

station locations, parameters sampled, and sampling frequencies) to demonstrate 

reasonable progress; quality assurance/quality control elements that demonstrate 

the monitoring will comply with Rule 62-160, F.A.C.; procedures for entering all 

appropriate data into STORET; the responsible monitoring and reporting entity; 

the frequency and format for reporting results; the frequency and format for 

reporting on the implementation of all proposed management activities; and 

methods for evaluating progress towards goals. 

A Description of Proposed Corrective Actions—a description of proposed 

corrective actions (and any supporting document[s]) that will be undertaken if 

water quality does not improve after implementation of the management actions 

or if management actions are not completed on schedule, and a process for 

notifying the Department that these corrective actions are being implemented. 

Water Quality–Based Targets and Aquatic Ecological Goals 

Some of the most important elements listed above are the requirements to provide 

water quality–based targets or aquatic ecological goals and a discussion on how resultant 

pollutant(s) reduction targets/goals will result in restoration of designated uses. Some 

people have expressed concern about these targets because they equate a water quality–

based restoration target with a TMDL (thus assuming a “Catch 22” that a TMDL is 

needed to make a demonstration that a TMDL is not needed). However, as is also the 

case for TMDLs, water quality–based targets can take many forms, and need not be a 

result of a complex hydrodynamic/water quality model. 

In some cases, there may be sufficient historical data (paleolimnological data, 

loadings from periods predating the impairment, or baseline data for Outstanding Florida 

Waters2

, for example) that could be used to determine an appropriate water quality target. 

In other cases, simplified modeling (including regression analysis) may allow for 

conservative estimates of the assimilative capacity that could then be used as the basis for 

restoration goals. And, finally, a water quality target may have been developed that 

would be scientifically equivalent to (or act as the basis for) a TMDL, but the target has 

not been administratively adopted as a TMDL. In each of these cases, a sound water 

quality target could be used to evaluate whether the proposed pollution control 

mechanisms will sufficiently reduce loadings to meet the assimilative capacity of the 

water in question and result in attainment of designated uses.

 Baseline data would be data for the year prior to designation of the OFW. 
192 Water Quality Assessment Report: Springs Coast

Interim Targets 

Because it will usually take many years to restore fully the designated uses of an 

impaired water, interim water quality targets will often be needed to measure whether 

reasonable progress is being made towards the restoration of designated uses. Examples 

of such interim targets are provided in the last section of this document, but site-specific 

measures are also encouraged. 

Averaging Periods for Water Quality Targets 

While the averaging period for water quality–based targets should be consistent with 

how the underlying standard is expressed, they can often be expressed in a variety of 

ways and need not be expressed as “daily loads.” Annual averages or medians are often 

appropriate for some parameters, but shorter-term (seasonal, for example) averages may 

be necessary if the impairment is limited to specific seasons or parts of the year. Multiyear averages may be appropriate in limited circumstances where there is naturally high 

variation of the water quality target. 

Estimates of Pollutant Reductions from Restoration Actions 

It will often be difficult to estimate precisely the pollutant reductions that will result 

from specific restoration activities. This is particularly true for the implementation of 

best management practices (BMPs). However, to provide reasonable assurance that a 

BMP or other restoration action will reduce loadings of the pollutant of concern to a level 

that will restore the water’s designated uses, documentation should address how the 

reductions were calculated, including providing documented values from the scientific 

literature for reductions attributed to similar management actions. If the expected 

reductions are expressed as a range, the midpoint of the range should be used as the basis 

for estimating reductions, unless documentation is provided supporting the use of 

different removal efficiencies in this specific application. 

New Sources/Growth 

Another key element is the discussion on how future growth and new sources will be 

addressed. Restoration goals must address possible increased loadings of the pollutant of 

concern that are anticipated due to population growth or land use changes in contributing 

watersheds, both from point and nonpoint sources. This will be particularly important for 

waters impaired by nutrients, given that so many Florida watersheds are faced with 

continuing urban, residential, and agricultural development that results in increased 

nutrient loading from stormwater, septic tanks, and wastewater discharges. 

Examples of Reasonable Progress 

The determination of whether there will be reasonable progress towards attainment 

of water quality standards will be very site- and pollutant-specific. Documentation 
Water Quality Assessment Report: Springs Coast 193

should be provided supporting specific progress towards restoration of the designated 

uses of the impaired water. Possible examples of reasonable progress include, but are not 

limited to the following: 

• A written commitment to implement controls reducing loadings within a specified 

time frame from watershed stakeholders representing at least 50 percent of the 

anthropogenic load of the pollutant(s) of concern; 

• Evidence of at least a 10 percent reduction (or alternatively, a percent reduction 

consistent with meeting the water quality target by the specified date) in annual 

anthropogenic loading of the pollutant(s) of concern; 

• Evidence of at least a 10 percent decrease (or alternatively, a percent decrease 

consistent with meeting the water quality target by the specified date) in the annual 

average concentration of the pollutant(s) of concern in the water; 

• Bioassessment results showing there has been an improvement in the health of the 

biological community of the water, as measured by bioassessment procedures similar 

to those used to determine impairment and conducted in similar conditions; or 

• Adoption of a local ordinance that specifically provides water quality goals, restricts 

growth or loads tied to the pollutant(s) of concern, and provides an enforcement 

option if the proposed management measure(s) are not implemented as required. 

Reasonable progress must be made by the time the next 303(d) list is due to be 

submitted to EPA, which is currently every two years. EPA has contemplated changing 

the listing cycle to every four or five years, and the IWR was specifically worded to 

allow a longer time frame for requiring reasonable progress in the event that the listing 

cycle changes. 

Long-Term Requirements

If at any time the Department determines that reasonable assurance and reasonable 

progress are not being met, the order adopting the Verified List will be amended to 

include the waterbody on the Verified List for the pollutant(s) in question. Additional 

reasonable progress must be made each time a waterbody is considered for listing under 

Rule 62-303, F.A.C. (every five years).

Appendix D: Methodology for Determining Impairment Based 

on the Impaired Surface Waters Rule 

The Impaired Surface Waters Rule 

To identify impaired waters in each of the state’s river basins, the Florida 

Department of Environmental Protection (Department) evaluates water quality data using 

the science-based methodology in the Identification of Impaired Surface Waters Rule 

(IWR) (Rule 62-303, Florida Administrative Code [F.A.C.]). The rule establishes 

specific criteria and thresholds for impairment, in addition to data sufficiency and data 

quality requirements. The methodology described in the rule is based on a statistical 

approach designed to provide greater confidence that the outcome of the water quality 

assessment is correct. The complete text of the IWR is available at 

http://www.dep.state.fl.us/legal/Rules/shared/62-303/62-303.pdf. 

As part of the watershed management approach, for each river basin in the state the 

Department will follow the methodology in Section 62-303.300, F.A.C., to develop a 

Planning List of potentially impaired waters to be assessed under Subsections 403.067(2) 

and (3), Florida Statutes (F.S.). The methodology for developing the Planning List 

includes an evaluation of aquatic life use support, primary contact and recreational use 

support, fish and shellfish consumption use support, drinking water use support, and 

protection of human health. Data older than 10 years cannot be used to evaluate water 

quality criteria exceedances for the Planning List. As required by Subsection 403.067(2), 

F.S., the Planning List will not be used to administer or implement any regulatory 

program, and is submitted to the U.S. Environmental Protection Agency (EPA) for 

informational purposes only. 

After further assessment, using the methodology in Part III, Section 62-303.400, 

F.A.C., the Department will determine if waters on the Planning List are, in fact, 

impaired and if the impairment is caused by pollutant discharges. These waters are 

placed on a Verified List. The criteria for the Verified List are more stringent than those 

for the Planning List. Data older than 7.5 years should not be used to verify impairment. 

The Verified List will be adopted by Secretarial Order and forwarded to the EPA for 

approval as Florida’s Section 303(d) list of impaired waters. The Department will 

develop TMDLs for these waters under Subsection 403.067(4), F.S. 

Attainment of Designated Use(s) 

While the designated uses of a given waterbody are established using the surface 

water quality classification system described previously, it is important to note that the 

EPA uses slightly different terminology in its description of designated uses. Because the 

Department is required to provide use attainment status for both the state’s 305(b) report 

and the state’s 303(d) list of impaired waters, the Department uses EPA terminology 

when assessing waters for use attainment. The water quality evaluations and decision 

processes for listing impaired waters that are defined in Florida’s IWR are based on the 

following designated use attainment categories:

Sources of Data 

The Department’s assessment of water quality for each basin statewide includes an 

analysis of quantitative data from a variety of sources, many of which are readily 

available to the public. These sources include the EPA’s Legacy and Modernized 

STOrage and RETrieval (STORET) Databases, the U.S. Geological Survey (USGS), the 

Department, the Florida Department of Health (FDOH), the water management districts, 

local governments, and volunteer monitoring groups. 

Historically, the Department carried out statewide water quality assessments using 

data available in the EPA’s Legacy STORET Database; STORET makes up 

approximately 60 percent of the statewide data used in the IWR assessment. The Legacy 

STORET dataset is a repository of data collected and uploaded by numerous 

organizations through 1999. The Legacy STORET Database can be accessed at 

http://www.dep.state.fl.us/water/storet/index.htm. 

In 2000, the EPA created a modernized version of STORET that included new 

features designed to address data quality assurance/quality control concerns (see the new 

STORET Web site at http://www.epa.gov/storet/. However, because of software 

difficulties associated with batch uploading of data to Modernized STORET, the data 

being uploaded to the national repository decreased dramatically, and lingering problems 

have temporarily reduced STORET’s importance as a statewide data source. It houses 

only about 5 percent of the statewide IWR Database. 

Approximately 35 percent of the data used in the IWR assessment was provided by 

individual organizations that for various reasons, such as time constraints or resource 

limitations, were not able to enter their data into the national database. The organizations 

providing the largest datasets include the South Florida, Southwest Florida, and St. Johns 

River Water Management Districts; the USGS; and the University of Florida LakeWatch 

volunteer monitoring group. Several of these databases are readily available to the public 
196 Water Quality Assessment Report: Springs Coast

via the Internet: the South Florida Water Management District at 

http://www.envirobase.usgs.gov/, the USGS at http://water.usgs.gov/, and LakeWatch at 

http://lakewatch.ifas.ufl.edu/. 

The Department created the IWR Database in 2002 to evaluate data simultaneously 

in accordance with the IWR methodology for every basin in the state, based on the 

appropriate data “window.” For the Verified List assessment, the window is 7.5 years 

(for the IWR Database), and the Planning List assessment window is 10 years. Table 

D.2 shows the periods of record for the Verified and Planning Lists for the 5 basin 

groups. 

The evaluation of water quality in the state’s basins also includes some qualitative 

information. These sources are described in the Water Quality Status Reports and Water 

Quality Assessment Reports for each basin.

Methodology 

To determine the status of surface water quality in individual river basins in Florida, 

three categories of data—chemistry data, biological data, and fish consumption 

advisories—were evaluated to determine potential impairments for the four designated 

use attainment categories discussed earlier: aquatic life, primary contact and recreation, 

fish and shellfish consumption, drinking water use, and protection of human health. 

Aquatic Life Based Attainment 

The IWR follows the principle of independent applicability. A waterbody is listed 

for potential impairment of aquatic life use support based on exceedances of any one of 

four types of water quality indicators (numeric water quality criteria, nutrient thresholds, 

biological thresholds, and toxicity data). 
Water Quality Assessment Report: Springs Coast 197

EXCEEDANCES OF NUMERIC WATER QUALITY CRITERIA

The chemistry data from STORET used in evaluating impairment were also used for 

preparing the state’s 305(b) report. Only ambient surface water quality stations were 

included in the assessment of impairment. Water quality information from point sources 

or wells was excluded. Monitoring stations were classified as one of five waterbody 

types—spring, stream, lake, estuary, or blackwater—based on criteria described in the 

latest 305(b) report. The assessments included the following parameters: 

Metals Arsenic, aluminum, cadmium, chromium VI, chromium III, 

copper, iron, lead, mercury, nickel, selenium, silver, 

thallium, and zinc 

Nutrients Chlorophyll a for streams and estuaries, and Trophic State 

Index (TSI) (chlorophyll a, total nitrogen, and total 

phosphorus) for lakes 

Conventionals Dissolved oxygen (DO), fecal coliform, total coliform, pH, 

unionized ammonia 

The requirements for placing waters on the Planning List included a minimum of 10 

temporally independent samples from the 10-year period of record shown in Table D.2,

unless there were 3 exceedances of water quality or 1 exceedance of an acute toxicity 

criterion in a 3-year period. The screening methodology for the Verified List requires at 

least 20 samples from the last 5 years preceding the Planning List assessment. An 

exceedance, meaning that water quality criteria or standards are not met, is recorded any 

time the criterion is exceeded by any amount. An exceedance for DO, however, means 

that a waterbody does not meet the DO criterion, rather than an actual exceedance of the 

criterion. 

To determine if a waterbody should be placed on the Planning List for each 

parameter, the chemical data were analyzed using a computer program written to assess 

the data, based on criteria established in the IWR, with two exceptions. First, unionized 

ammonia data were not analyzed by the program, but rather with an Excel spreadsheet. 

Second, because the full complexity of the pH criterion could not be programmed, the 

incomplete listings for pH are not included. They will be further examined while 

additional data are collected during Phase 2 of the watershed management cycle. Data 

analysis and statistical summaries of waterbody identification numbers (WBIDs), 

waterbody types, and parameters obtained from the STORET Database were conducted 

using Access, SAS statistical software, and ArcView geographic information system 

(GIS) applications 

The data for metals and conventional parameters were compared with the state 

surface water quality criteria in Section 62-302.530, F.A.C. (IWR). The rule contains a 

table of sample numbers versus exceedances. A waterbody was placed on the Planning 

List if there was at least 80 percent confidence that the actual criteria exceedance rate was 
198 Water Quality Assessment Report: Springs Coast

greater than or equal to 10 percent. To be placed on the Verified List, at least a 90 

percent confidence rate was required. 

EXCEEDANCES OF NUTRIENT THRESHOLDS

The state currently has a narrative nutrient criterion instead of a numeric value for 

nutrient thresholds. The narrative criterion states, “In no case shall nutrient 

concentrations of a body of water be altered so as to cause an imbalance in natural 

populations of aquatic flora or fauna.” The IWR provides an interpretation of the 

narrative nutrient criterion. In general, the TSI and the annual mean chlorophyll a values 

are the primary means for assessing whether a waterbody should be assessed further for 

nutrient impairment. 

The rule also considers other information that might indicate an imbalance in flora or 

fauna due to nutrient enrichment, such as algal blooms, excessive macrophyte growth, a 

decrease in the distribution (either in density or aerial coverage) of seagrasses or other 

submerged aquatic vegetation, changes in algal species richness, and excessive diel 

oxygen swings. 

Potential nutrient impairment was evaluated by calculating annual mean chlorophyll 

a values for estuaries and streams and the TSI for lakes. For lakes, the TSI was 

calculated using chlorophyll a, total phosphorus, and total nitrogen measurements. Direct 

evidence of imbalances of flora and fauna in waterbodies was also considered in the 

evaluation of nutrient impairments. 

In estuarine areas, a water was considered nutrient enriched if the annual mean 

chlorophyll a values were greater than 11 micrograms per liter (μg/L), or if annual mean 

chlorophyll a values increased by more than 50 percent over historical values for at least 

two consecutive years. For streams, a water was considered nutrient enriched if the 

annual mean chlorophyll a values were greater than 20 μg/L, or if the annual mean 

increased by more than 50 percent over historical values for at least two consecutive 

years. 

A lake with a mean color greater than 40 platinum cobalt units (PCUs) was 

considered nutrient enriched if the annual mean TSI exceeded 60. A lake with a mean 

color less than or equal to 40 PCUs was considered nutrient enriched if the annual mean 

TSI exceeded 40. In addition, a lake was considered nutrient enriched if there was an 

increase in TSI over the 1989 to 2000 period, or if TSI measurements were 10 units 

higher than historical values. 

EXCEEDANCES OF BIOLOGICAL THRESHOLDS

Bioassessments were carried out for streams, lakes, canals, and rivers using the IWR 

as guidance and following the Department’s standard operating procedures, which 

provide definitions and specific methods for the generation and analysis of bioassessment 

data. These are referenced in the individual bioassessment data tables contained in the 

Status Reports. The purpose behind using a bioassessment methodology in surface water 

characterizations is that biological components of the environment manifest long-term 

water quality conditions and thus provide a better indication of a waterbody’s true health 

than discrete chemical or physical measurements alone. Similar to water quality criteria, 
Water Quality Assessment Report: Springs Coast 199

bioassessment methods involve the identification of a biological reference condition, 

based on data from unimpaired or least impacted waters in a given region. 

For the Planning and Verified List assessments, the reference condition data were 

used to establish expected scores, ranging from best to worst, for various measures of 

community structure and function, such as numbers or percentages of particular species 

or feeding groups. Data on community structure and function from waters of unknown 

quality in the same region as reference waters were compared with the expected scores of 

metrics to evaluate their biological integrity. 

Metrics (e.g., number of taxa, percent Diptera, percent filter feeders) were used 

independently and as an aggregated group called an index. Indices have advantages over 

individual metrics in that they can integrate several related metrics into one score that 

reflects a wider range of biological variables. A number of bioassessment metrics and 

indices exist for assessing populations of plant and animal life, including fish, diatoms 

(e.g., microscopic algae and unicellular plankton), and macroinvertebrates (e.g., insects, 

crayfish, snails, and mussels). 

Only macroinvertebrate data from ambient sites in state surface waters were used in 

the bioassessments analyzed for the Planning and Verified Lists. The data included sites 

designated as test and background sites for National Pollutant Discharge Elimination 

System (NPDES) fifth-year inspections, but excluded data from effluent outfalls from 

discharging facilities, or data from monitoring sites not clearly established to collect 

ambient water quality data. Because site-specific habitat and physicochemical 

assessment information (e.g., percent suitable macroinvertebrate habitat, water velocities, 

extent of sand or silt smothering, and riparian [Definition: Of, on, or relating to the 

banks of a natural course of water.] buffer zone widths) was not available at the time of 

reporting, it was not included. However, this information is instrumental in pinpointing 

the causes for failed bioassessment metrics and will be included in future reporting. 

The data used to develop the Planning and Verified Lists were obtained from the 

Department’s Biological Database (SBIO) and the EPA’s STORET Water Quality 

Database, where it could be substantiated that the data were generated in compliance with 

the bioassessment standard operating procedures referenced in the IWR (Section 62-

303.330, F.A.C.). 

The data from these databases are used without regard to the randomness of sample 

site selection. For the purposes of the Status Reports, the seasons are defined as follows: 

winter (1/1–3/31), spring (4/1–6/30), summer (7/1–9/30), and fall (10/1–12/31). Wet 

seasons are generally spring and summer, and dry seasons are fall and winter, although 

conditions can vary in the state as a whole. 

LAKE CONDITION INDEX

The scoring of the individual metrics of the Lake Condition Index (LCI), except 

percent Diptera, was performed according to the following formula: 

100(B/A) where A = the 95 percentile of the reference population and B = observed 

value 
200 Water Quality Assessment Report: Springs Coast

For percent Diptera, the following formula was used: 

100 (100-B)/(100-A) where A = the 95 percentile of the reference population and B 

= observed value 

An average LCI score was calculated by averaging the scores of the six metrics in 

the method: total number of taxa; total number of taxa belonging to the orders 

Ephemeroptera, Odonata, and Trichoptera (EOT taxa); percent EOT taxa; Shannon–

Wiener Diversity Index score; Hulbert Index score; and percent Dipteran individuals. 

LCI calculations were only provided for clear lakes (< 20 PCUs). As macroinvertebratebased indices have not been shown to assess colored lakes in Florida accurately (> 20 

PCUs), they have been excluded from bioassessments. A poor or very poor rating based 

on the average score constituted a failed bioassessment, based on the IWR. 

STREAM CONDITION INDEX

A total Stream Condition Index (SCI) score was calculated by adding the scores of 

the seven metrics in the method: total number of taxa; total number of taxa belonging to 

the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT taxa); percent Chironomid 

taxa; percent dominant taxa; percent Diptera; percent filter feeders; and Florida Index. A 

poor or very poor rating based on the total score constituted a failed bioassessment, based 

on the IWR. The Water Quality Status Reports contain definitions and specific methods 

for the generation and analysis of bioassessment data. 

BIORECON

To establish an impairment rating based on BioRecon data, three metrics were used: 

the Florida Index score, total number of taxa, and total number of EPT taxa. If all three 

metrics failed to meet thresholds, the water was deemed “impaired” based on the IWR. 

BIOLOGICAL INTEGRITY STANDARD 

Quantitative data, generated through the use of Hester–Dendy artificial substrate 

samplers, were used to calculate Shannon–Wiener Diversity Index scores for paired 

background and test sites, as specified in the Biological Integrity Standard of Subsection 

62-302.530(11), F.A.C. One failure of the standard meant that a waterbody segment was 

listed as potentially impaired. 

EVALUATION OF TOXICITY DATA

Although the IWR describes the use of toxicity data for the assessment of aquatic 

life-based attainment, no ambient toxicity data are available for assessment and this 

metric was not used. 
Water Quality Assessment Report: Springs Coast 201

Primary Contact and Recreation Attainment 

For Class I, II, or III waters, a waterbody was potentially impaired if the following 

criteria were met: 

• The waterbody segment did not meet the applicable water quality criteria for 

bacteriological quality, 

• The waterbody segment included a bathing area that was closed by a local health 

department or county government for more than 1 week or more than once during a 

calendar year based on bacteriological data, 

• The waterbody segment included a bathing area for which a local health department 

or county government issued closures, advisories, or warnings totaling 21 days or 

more during a calendar year based on bacteriological data, or 

• The waterbody segment included a bathing area that was closed or had advisories or 

warnings for more than 12 weeks during a calendar year based on previous 

bacteriological data or on derived relationships between bacteria levels and rainfall or 

flow. 

Fish and Shellfish Consumption Attainment 

For Class I, II, or III waters, a waterbody was potentially impaired if it did not meet 

the applicable Class II water quality criteria for bacteriological quality, or if a fish 

consumption advisory had been issued. Fish consumption advisories were based on the 

FDOH’s “limited consumption” or “no consumption” advisories for surface waters 

because of high levels of mercury in fish tissue. In addition, for Class II waters, 

waterbody segments that had been approved for shellfish harvesting but were 

downgraded to a more restrictive classification were listed as potentially impaired. 

Drinking Water Attainment and Protection of Human Health 

For Class I waters, a waterbody was potentially impaired if it did not meet the 

applicable Class I water quality criteria.

 Class I landfills receive an average of 20 tons or more of solid waste per day, while Class II landfills receive an average 

of less than 20 tons of solid waste per day. Both Class I and Class II landfills receive general, nonhazardous household, 

commercial, industrial, and agricultural wastes, subject to the restrictions of Sections 62-701.300 and 62-701.520, F.A.C. 

Class III landfills are those that receive only yard trash, construction and demolition debris, waste tires, asbestos, carpet, 

cardboard, paper, glass, plastic, furniture other than appliances, or other materials approved by the Department that are 

not expected to produce leachate that poses a threat to public health or the environment. They do not accept putrescible 

household waste.
