Water Quality Assessment Report: Indian River Lagoon 7

Executive Summary

Indian River Lagoon

The Indian River Lagoon (IRL) ecosystem is a 155-mile-long estuary 

located along Florida’s east-central coast. The ecosystem begins at Ponce 

de Leon Inlet near New Smyrna Beach in Volusia County and extends 

southward to Jupiter Inlet in Palm Beach County. It includes Mosquito 

Lagoon, Indian River Lagoon (northern, central, and southern parts), 

Banana River, and the St. Lucie River and Estuary. Within the Florida 

Department of Environmental Protection’s (Department’s) Total Maximum Daily Load (TMDL) Program, the IRL Group 5 Basin includes 

the waters and watersheds of Mosquito Lagoon, the northern and central 

parts of the Indian River Lagoon, and the Banana River only. The IRL 

Basin lies in Volusia, Brevard, and Indian River Counties, and it is located 

within the jurisdiction of the St. Johns River Water Management District 

(SJRWMD). The IRL Basin does not include the southern part of the 

Indian River Lagoon or the St. Lucie River and Estuary, which are TMDL 

Group 2 waters located within the jurisdiction of the South Florida Water 

Management District. 

The Water Quality Assessment Report for the IRL Basin is part of the 

implementation of the Department’s watershed management approach for 

restoring and protecting water resources and addressing 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 IRL 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 Department 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 an assessment of ground water quality 

and ground water to surface water interactions in the basin. It discusses 

 priorities for further evaluation, resource priorities, and proposed actions. 

Water Quality Assessment Report: Indian River Lagoon 9
(See Noteworthy in Chapter 1 for a description of the contents of this 

report, by chapter.)

In the IRL 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 Indian River Lagoon National Estuary Program, SJRWMD, Brevard 

County, and the Marine Resources Council (MRC).

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 

SJRWMD, Florida Department of Agriculture and Consumer Services 

(DACS), MRC, Volusia County, Brevard County, Florida Department of 

Health, and the Department.

During the next few years, further data collection and analysis will be 

done to establish TMDLs for impaired waters in the IRL 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 68 waterbodies or waterbody 

segments in the IRL Basin are impaired and 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. Figure 3.2 

and Figures 3.4 through 3.8 (in Chapter 3) depict the results of this 

 evaluation.

Banana River Planning Unit

Of the 14 waterbody segments in the Banana River Planning Unit, 

14 segments have suffi cient data for assessment. Of these, 14 are verifi ed 

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

List, and none meet standards.

The 14 verifi ed impaired segments in the planning unit, and the 

parameters of impairment, are as follows:

Total Maximum Daily Load Priority Areas

There are 21 high-priority areas for TMDL development in the IRL 

Basin. Section 62-303.500, Florida Administrative Code, defi nes highpriority waters as 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 EPA’s 1998 303(d) list as high priority.

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

development are as follows. (Note: There are no high-priority areas in the 

Mosquito Lagoon Planning Unit.)

14 Water Quality Assessment Report: Indian River Lagoon
All of the remaining parameters causing impairment in the waterbody 

segments on the Verifi ed List have been assigned a medium priority for 

TMDL development. 

Summary of Ground Water Findings

Due to the signifi cant interaction between ground water and surface 

water throughout the basin, ground water may infl uence surface water quality and should be considered in evaluations of sources causing impairments.

Basinwide Observations of Elevated Parameter Concentrations

The highest levels of ammonia and ammonia+organic nitrogen in shallow ground water are found in the Banana River Planning Unit. However, 

ground water concentrations of these nutrients in all planning units except 

Mosquito Lagoon are elevated, compared with those for ground water in 

the entire SJRWMD. However, these levels are not higher than the medians for typical streams in Florida.

Phosphorus is elevated in the surfi cial aquifer throughout much of 

the basin, based on available data, and is likely due to natural conditions. 

Phosphorus, ammonia, and organic nitrogen are particularly elevated in the 

surfi cial aquifer of the Banana River Planning Unit.

Median concentrations of iron in the surfi cial aquifer wells are elevated 

in all of the basin’s planning units with data, suggesting that naturally 

elevated iron in ground water is also a source of elevated iron in surface 

waters, where ground water to surface water pathways are present.

Banana River Planning Unit

Three estuarine waterbodies (WBIDs 3044A, 3057B, and 3057C) 

are listed as impaired because of low DO. WBID 3044A is a harbor in 

the Banana River, and WBIDs 3057B and 3057C are segments of the 

Banana River. Total nitrogen is the causative pollutant for low DO in all 

three estuarine waterbodies. In the surfi cial aquifer, median ammonia and 

ammonia+organic nitrogen concentrations were the highest of all planning 

units in the basin. In addition, orthophosphate and phosphorus concentrations were highest in the planning unit’s surfi cial aquifer. The nutrients 

in ground water and these impaired surface waters may have sources in 

common, with ground water discharge providing a portion of the nutrient 

load to these waters.

Mosquito Lagoon Planning Unit

No waterbodies in the planning unit are currently listed as impaired. 

Data from the surfi cial aquifer indicate that ground water quality is similar 

to that of the North IRL Planning Unit.

North Indian River Lagoon Planning Unit 

Three waterbody segments are listed as impaired for low DO (WBIDs 

2963D, 2963F, and 3028); all are classifi ed as estuaries of the Indian 

River except for Addison Creek (WBID 3028), which is a freshwater 

stream. In addition, two segments, Indian River above NASA Causeway 

Water Quality Assessment Report: Indian River Lagoon 15
(WBID 2963E) and Indian River above M. Brewer (WBID 2963F) are 

listed for nutrients (chlorophyll a). Phosphorus is elevated in general and 

is several times higher in shallow ground water than it is in surface waters 

of the planning unit; thus, the ground water contribution of phosphorus 

should be considered.

North Central Indian River Lagoon Planning Unit 

Four estuarine segments in the planning unit (WBIDs 2963B, 3082, 

3085A, and 3098) are impaired by low DO. Ground water is a potential 

contributing source of nutrients to surface waters in the planning unit and 

should be considered because of its potential contribution of phosphorus.

South Central Indian River Lagoon Planning Unit 

Several waterbodies in the planning unit are listed as impaired for low 

DO (WBIDs 3128, 3129A, 3129B, 3135, 3147, 3153, and 3158), and the 

North Prong Sebastian River (WBID 3128) is listed as impaired by iron. 

The median phosphorus level in the planning unit’s surfi cial aquifer is 

much higher than the phosphorus in surface waters, so phosphorus contributions by ground water should be considered. While the North Prong 

Sebastian River (WBID 3128) is listed for iron, naturally elevated iron 

in surface water is characteristic of the area. Shallow ground water in the 

vicinity is also high in iron. In addition, human-induced erosion of sediments and other activities in the intensively managed citrus area drained by 

the North Prong Sebastian River could cause elevated iron concentrations 

in the river.

20 Water Quality Assessment Report: Indian River Lagoon
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 Water Quality 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 Indian River Lagoon (IRL) 

Basin. A copy of the report can be found at http://www.dep.state.fl .us/

water/tmdl/stat_rep.htm.

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 

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, 68 waterbodies or waterbody segments 

in the IRL 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 the FWRA, 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: Indian River Lagoon 21
with the FWRA and the 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 IRL 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 3.4 through 3.8 in Chapter 3 

provide an integrated assessment for the IRL 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 are 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 

IRL Basin. Signifi cant data providers are St. Johns River Water Management District, Florida Department of Agriculture and Consumer Services, 

Marine Resources Council, Volusia County, Brevard County, Florida 

Department of Health, and the Department.

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

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 Central District

Figure 1.1 shows the order in which the Department’s Central 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.

The Ocklawaha Group 1 Basin was the fi rst basin in the district to 

undergo a preliminary assessment in 2000. A preliminary assessment of 

the Middle St. Johns Group 2 Basin was completed in 2001. The Upper 

St. Johns Group 3 Basin was assessed on a preliminary basis in 2002. 

 Similarly, a preliminary assessment for the Kissimmee Group 4 Basin was 

initiated in 2003, and the preliminary assessment of the IRL Group 5 

Basin was begun in 2004. In 2005, the cycle resumed with the Ocklawaha 

Group 1 Basin.

Indian River Lagoon

Chapter 2: Basin Overview

Basin Setting

The Indian River Lagoon (IRL) ecosystem is a 155-mile-long estuary 

located along Florida’s east-central coast. The ecosystem begins at Ponce 

de Leon Inlet near New Smyrna Beach in Volusia County and extends 

southward to Jupiter Inlet in Palm Beach County. It includes Mosquito 

Lagoon, IRL (northern, central, and southern parts), Banana River, and the 

St. Lucie River and Estuary. Within the Florida Department of Environmental Protection’s (Department’s) Total Maximum Daily Load (TMDL) 

Program, the IRL Group 5 Basin includes the waters and watersheds of 

Mosquito Lagoon, the northern and central parts of the IRL, and the 

Banana River only. The IRL Basin lies in Volusia, Brevard, and Indian 

River Counties, and it is located within the jurisdiction of the St. Johns 

River Water Management District (SJRWMD). The IRL Basin does not 

include the southern part of the IRL or the St. Lucie River and Estuary, 

which are TMDL Group 2 waters located within the jurisdiction of the 

South Florida Water Management District (SFWMD). Figure 2.1 shows 

the principal geopolitical features in the IRL Basin. 

The IRL Basin has geomorphic land features that may date back as 

long ago as 420,000 years (SJRWMD, 1996), shaped by the rise and fall 

of the sea. The basin’s major waterbodies are 3 elongated saline lagoons: 

Mosquito Lagoon, IRL (northern and central parts), and the Banana River 

(IRL lagoon system). These lagoons separate the mainland of Florida from 

a strip of barrier islands that extend north and south of two unique land 

features, Cape Canaveral and Merritt Island.

The IRL Basin is an important economic and biological resource 

within Florida. More than 50 percent of the Florida east coast fi sh catch 

and historically 90 percent of Florida’s clam harvest come from the basin. 

Clam harvests have declined in recent years (Steward, 2006). The basin 

is also an important producer of Florida’s Indian River citrus. Biological diversity is high in the basin, with more than 4,000 animal and plant 

 species recorded, including 36 rare and endangered animal species. 

Space exploration and the military have a prominent presence in the 

basin. Kennedy Space Center is located on north Merritt Island. The large 

tracts of land needed by the Space Center for security and facilities resulted 

in the acquisition of 140,000 acres of beaches, dunes, fl atwoods, wetlands, 

and marshes for the Merritt Island National Wildlife Refuge. The military 

maintains bases at Patrick Air Force Base and Cape Canaveral Air Force 

Base. Much of the industry in the Brevard County portion of the basin 

provides support for space exploration and military operations.

Water Quality Assessment Report: Indian River Lagoon 27
Figure 2.1: Geopolitical Map of the Indian River Lagoon Basin

28 Water Quality Assessment Report: Indian River Lagoon
Major mainland municipalities are New Smyrna Beach, Titusville, 

Cocoa, Rockledge, Merritt Island, Melbourne, Palm Bay, Sebastian, 

and Vero Beach. Major barrier island beachside communities are 

Cape Canaveral, Cocoa Beach, Satellite Beach, Indian Harbour Beach, 

 Indialantic, and Melbourne Beach.

Growth in the basin, like much of Florida, has accelerated tremendously since the 1950s. The expansion of tourism, the space industry 

associated with space exploration, and agriculture—coupled with improvements in access to the basin and control of mosquitoes—helped fuel growth 

(Woodward-Clyde Consultants, 1994a). Since 1950, the combined population of Volusia, Brevard, and Indian River Counties has increased from well 

under 200,000 people to about 1 million people. The population continues 

to grow and is projected to be about 1.4 million in 2020. The basin also 

contains Palm Bay, one of the fastest growing cities in the United States.

About 160 miles of roadway have been designated as the Indian River 

Scenic Highway (Florida Department of Transportation, 2005). The scenic 

route follows a southern loop starting from the Lagoon House on U.S. 

Highway 1 before looping east on the Wabasso Causeway and then north 

along State Road A1A.

Surface Water Resources

Primary surface water resources in the IRL Basin are Mosquito 

Lagoon, IRL (northern and central parts), and the Banana River. These 

waters comprise a saline lagoon system (IRL lagoon system) that runs 

parallel to Florida’s east coast, and separates the mainland from a string of 

barrier islands. Figure 2.2 shows the locations of the largest waterbodies in 

the IRL Basin. A more detailed discussion in Chapter 3 provides information on each planning unit.

Mosquito Lagoon extends from Ponce de Leon Inlet south to a dune 

ridge located between Mosquito Lagoon and the Banana River. The 

northern part of Mosquito Lagoon’s watershed drains largely salt marsh and 

mangrove marsh. The western boundary of Mosquito Lagoon is a poorly 

defi ned dune ridge. Mosquito Lagoon is connected to the IRL by the 

Haulover Canal. South of Haulover Canal, the dune ridge forms part of 

northern Merritt Island. 

The North to South Central IRL extends from Turnbull Creek south 

to Indian River County/St. Lucie County. Major cities from which it 

receives drainage include Titusville, Cocoa, Rockledge, Merritt Island, 

Eau Gallie, Melbourne, Sebastian, and Vero Beach. From north to south, 

major tributaries to the North to South Central IRL include Turnbull 

Creek, Canaveral Barge Canal, the valley between Ten Mile Ridge and the 

Atlantic Coastal Ridge, Eau Gallie River (receives drainage from the city of 

Melbourne), Crane Creek (receives drainage from the cities of Melbourne 

and Melbourne Village), Turkey Creek (receives drainage from urbanized 

areas of the city of Palm Bay and agriculture), C-1 and C-54 Canals (fl owing from the Upper St. Johns River Basin), Goat Creek, Kid Creek (drains 

Valkaria Airport and Missile Tracking Annex), Trout Creek, and the North

The Banana River is essentially a lagoon with a central channel. It 

lies between Merritt Island and the coastal barrier islands. It extends in a 

north-south direction from Banana Creek south to the Eau Gallie Causeway. Sykes Creek (a small lagoon system) and Newfound Harbor are the 

primary tributaries to the Banana River. 

A description of the basin’s physiographic features and factors affecting 

the hydrology, hydrodynamics, and water quality of the basin is provided 

below. A description of surface water classifi cations and special designations applicable to the basin is also provided. 

Physiographic Features

The geologic history of the basin has shaped its physical form and 

ultimately infl uenced the location of surface water resources. The basin’s 

surface features were created and shaped by the rise and fall of the sea. 

Barrier islands that extend north and south of Cape Canaveral and Merritt 

Island form the eastern boundary of the basin. West Merritt Island may 

well have formed when sea levels were lower. Rising sea levels eroded the 

Merritt Island beach and formed a sandbar offshore to the east. Once sea 

levels receded, the sandbar was reworked to form the Banana River Lagoon 

and Cape Canaveral. It is believed that the southern barrier islands developed as sand was moved south from Cape Canaveral. 

When water levels were higher, plains were formed from erosion by 

waves and currents. These plains became terraces or fl atlands when the 

water receded. The terraces in the basin, in order of decreasing elevation, 

are the Pamlico and Silver Bluff Terraces. Dunes formed on these terraces 

parallel to and west of the basin. Higher ridges formed on the dunes. The 

Atlantic Coastal Ridge formed on the Silver Bluff Terrace, and the Ten 

Mile and Green Ridges formed on the Pamlico Terrace.

Hydrodynamics, Hydrology, and Water Quality Effects

The IRL Basin’s climate is predominantly humid subtropical, with a 

dry season (mid-October to May) and a wet season (June to mid-October) 

(Knowles, 1995). Average rainfall in the basin ranges from 55 to 60 inches 

per year, with about 62 percent of the total rain falling from June through 

October (SJRWMD, 1996). The spatial distribution of rainfall across 

the basin has been historically variable, with the most rain falling in the 

Titusville area and the least falling between Palm Bay and Sebastian Inlet 

(Knowles, 1995).

Rainfall is distributed within the basin in many different forms. The 

IRL lagoon system receives saltwater inputs from the Atlantic Ocean 

through inlets. Connections to the Atlantic Ocean, moving north to 

south, are limited to Ponce de Leon Inlet, Port Canaveral entrance, Sebastian Inlet, Fort Pierce Inlet, and St. Lucie and Jupiter Inlets, some of which

de Leon and Jupiter Inlets are natural entrances to the lagoon. Fresh water 

enters the lagoon system from rainfall, surface water runoff, ground water 

seepage, and infl ows from tributary streams and drainage canals.

Historically, the basin’s drainage pattern consisted of a network of 

slow, meandering sloughs, creeks, rivers, and wetlands. The basin could 

absorb fl oodwaters and slowly release them either as surface water runoff 

to the lagoon system or as ground water recharge. Discharges into the 

three coastal lagoons only occurred after large storm events. To the east, 

the basin’s boundary was—and still is—defi ned by barrier island dune 

lines. The western boundary was delineated by uplands along the Atlantic 

Coastal Ridge and Green and Ten Mile Ridges.

Settlement of the IRL Basin and surrounding basins in the 1840s led 

to changes in the hydrology of the IRL lagoon system. In 1916, the lagoon 

system received drainage from about 572,000 acres (SJRWMD, 2005a). 

Today it receives drainage from 1.4 million acres. Much of this expansion was due to draining parts of the Lake Okeechobee Basin and Upper 

St. Johns River Basin for agriculture and development and diverting the 

associated waters to the IRL Basin via canals, such as the C-1 and C-54 

Canals. The 1916 Drainage Acts of Florida created special taxing districts 

to promote agriculture and provide fl ood and drainage control. A large 

part of the drainage works performed from 1916 to 1950 modifi ed almost 

all natural streams and interconnected lagoons within the IRL Basin 

through the construction of canals (Woodward-Clyde Consultants, 1994c). 

In addition, increased impervious surface area within the IRL Basin has 

contributed to increased stormwater runoff to the IRL lagoon system. All 

of these factors act to alter the timing and volume of stormwater releases 

to the lagoon system. It has been estimated that twice as much freshwater 

enters the IRL lagoon system compared with 100 years ago (WoodwardClyde Consultants, 1994c). A substantial amount of the stormwater 

volume is discharged in the fi rst few hours after a storm event.

Changes in stream discharge were the greatest south of Melbourne, 

with the Eau Gallie River, Turkey Creek, Sebastian River, Crane Creek, 

and Indian River Farms Water Control District Canals experiencing the 

greatest alterations in fl ow. Stormwater discharges carry large loadings 

of nutrients, sediments, and other pollutants into the lagoon system and 

fairly rapidly change salinity near the mouths of streams. Rapid changes in 

salinity can be detrimental to many marine and estuarine organisms.

Additional drainage canals were dug to accommodate urban expansion and mosquito control. Special taxing districts called mosquito 

control districts were created to address mosquito problems. South of 

Cape Canaveral, mosquito control districts used ditches and impoundments as mosquito control techniques (Woodward-Clyde Consultants, 

1994a). About 75 percent of the basin’s salt marshes, including those in 

the southern part of the IRL in Martin and St. Lucie Counties, have been 

impounded for mosquito control, reducing or eliminating their connection 

with the open waters of the lagoon system. North of Cape Canaveral, a 

140-mile network of drainage ditches was dug specifi cally for drainage to 

control mosquitoes (Woodward-Clyde Consultants, 1994a).

32 Water Quality Assessment Report: Indian River Lagoon
The construction and dredging of channels affect lagoon hydrodynamics. The Intracoastal Waterway was built to create a deepwater 

channel for navigation. The channel is maintained to a depth of 12 feet 

north of Fort Pierce and 10 feet south of Fort Pierce. Dredged material 

from the channel was often used to create spoil islands. The Intracoastal 

Waterway extends the entire length of Mosquito Lagoon and is connected 

to the Indian River via the Haulover Canal. The Banana River and Port 

Canaveral are connected to the Indian River by the Canaveral Barge Canal. 

The Banana River Channel and the Saturn Barge Canal extend the length 

of the Banana River.

The construction of various causeways over the lagoon system required 

fi lling parts of the shoreline at the causeway crossings. The open water area 

at these locations has been narrowed, which affects overall lagoon system 

water circulation, which is sluggish and mostly wind-driven. Limited tidal 

fl ushing with the Atlantic Ocean and the long, narrow, and shallow nature 

of the lagoon system further affect water circulation, making the lagoon 

system particularly vulnerable to the detrimental effects of introduced 

 pollutants. 

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)

Figure 2.3 depicts water use classifi cations and waters with special designations located in the IRL Basin. Large parts of the IRL, Banana River, 

and Mosquito River are classifi ed as Class II waters for shellfi sh harvesting 

and propagation, and they are divided into smaller manageable blocks of 

shellfi sh harvesting areas. Each area is classifi ed and managed to protect 

the public from disease and contamination associated with the consumption of shellfi sh. The harvesting of shellfi sh is an important contributor 

to the local economy. Potable surface water drinking supplies used in the 

basin are located outside its boundaries.

Special Designations

Outstanding Florida Waters

The waterbodies listed in Table 2.1 have been given additional protection through designation as Outstanding Florida Waters (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 

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.

Biological Resources

The IRL Basin is biologically unique because of a combination of 

climatological and physiographical features. It is where the tropical and 

temperate climate zones meet. Plants and animals found in the basin represent species that prefer a warm tropical climate alongside those that prefer 

cooler conditions. The long, narrow, north-to-south shape of the basin has 

helped increase the diversity of the biological communities present. Major 

differences occur in species composition between the northern and southern parts of the basin, and between the open waters of the basin and coastal 

areas. Appendix B contains supplementary information on the basin’s 

imperiled and endangered plants and animals.

Communities

The IRL Basin supports numerous upland, estuarine, marine, and 

freshwater habitats. Habitats range from longleaf pine forest to mangrove 

swamp. Coastal geology, topography, and latitude are important factors 

that determine community composition and distribution. 

Vegetation and land cover were mapped for the entire state by the 

Florida Fish and Wildlife Conservation Commission (FWC) using 2003 

Landsat imagery (Gilbert and Stys, 2004; Stys, Kautz, Reed, Kertis, 

Kawula, Keller, and Davis, 2004). Vegetation and land cover were grouped 

into 26 categories of natural and seminatural communities, 1 category 

for water, and an additional 16 categories of disturbed land cover types. 

Table 2.2 lists the common general natural community types found in 

the IRL Basin as delineated by Gilbert and Stys (2004). Descriptions of 

each habitat type are contained in Table B.1 in Appendix B. Additionally, 

unique habitat types exist in the form of spoil islands, impounded marshes, 

and seagrass beds.

Uplands

Prior to development, the IRL Basin’s upland communities comprised 

longleaf pine forest, pinelands, and xeric oak scrub maritime forest. The 

basin’s western side would have been composed of pine forest and scrub 

oak, which graded into salt marshes in the north and mangrove swamp 

in the south at the upper edge of the intertidal zone (Woodward-Clyde 

Consultants, 1994b). On the eastern or barrier island side of the basin, 

a change in vegetation occurs as one moves eastward from the maritime 

forest to coastal strand and beach dune communities. In the northern 

latitudes, live oak (Quercus virginiana) dominates the maritime forest. But 

approaching the area of Cape Canaveral, live oak is reduced in number as 

it reaches its southern limit and starts to be replaced by more tropical fl ora, 

such as gumbo limbo (Bursera simaurba), wild coffee (Psychotria undata), 

and wild tamarind (Lysiloma latisiliqua). 

The upland communities present on the eastern barrier islands are 

maritime hardwood hammock or forest, hardwood hammock, and coastal 

scrub. Maritime forest generally occurs on old stabilized dunes. Common 

plant species found in the maritime forest north of Cape Canaveral are live 

oak, saw palmetto, red bay, southern magnolia, and cabbage palm. South 

of Cape Canaveral, West Indian species become common. Hardwood 

hammocks north of Sebastian Inlet occupy an area that is transitional 

between swamp and upland forest. These communities usually occur as 

islands or small stands in depressions. South of Sebastian Inlet, and outside 

the area addressed in this report, tropical hardwood hammocks are the 

common hardwood hammock.

Coastal xeric oak scrub is the other major upland community found 

on the barrier islands. Scrub typically occurs on dry and well-drained sand 

dune areas. Large areas can still be found in the Merritt Island National 

Wildlife Refuge and on some private lands on Merritt Island. Evergreen 

oaks, myrtle oak, and Chapman oak dominate the scrub canopy. 

Wetlands

Both marine/estuarine and freshwater wetland communities are present 

in the basin. Wetlands play an important role in maintaining water quality. 

They function as fi lters, removing sediments, nutrients, and other runoff 

pollutants before they enter the IRL lagoon system. Wetlands also protect the shoreline from erosion by buffering the shoreline from the erosive 

energy generated by waves from storms or boats. 

Prominent marine and estuarine wetland coastal communities are salt 

marshes and mangrove marshes. Detritus produced in these wetlands is a 

major food source for aquatic animals. Wading birds forage in the marsh 

tidal creeks and impounded marshes for small fi sh and insects. Mangrove 

marshes provide roosting and nesting areas for many different species of 

wading birds. About 80 percent of the commercially and recreationally 

important fi sh species spend part of their life cycle in mangrove swamps 

(Woodward-Clyde Consultants, Marshall McCully & Associates, and 

Natural Systems Analysts, 1994). 

Much of the salt marsh habitat is found on Merritt Island and further 

north. Mangroves are excluded in the northern part of the basin because 

Water Quality Assessment Report: Indian River Lagoon 37
of periodic winter freezes. Natural berms along many of the basin’s salt 

marshes restrict fl ooding except during high tides, creating what is commonly called high marsh. The effect of this is to limit vegetation to highsalinity-tolerant species. The basin’s salt marshes provide critical habitat 

for rare and/or imperiled species. The now extinct dusky seaside sparrow 

utilized salt marshes as habitat. Impoundment of the marshes for mosquito control eliminated the sparrow’s habitat. The threatened Atlantic salt 

marsh snake (Nerodia fasciata taeniata) is found almost exclusively in the 

salt marshes bordering Mosquito Lagoon.

Mangrove marshes are dominated by red mangrove, black mangrove, 

and white mangrove. The distribution of the three species follows a gradient defi ned by water depth and frequency of inundation. Red mangroves 

inhabit deep water edges while black and white mangroves occur near or 

above the average high water line.

Freshwater wetlands in the basin are predominantly marsh and wet 

prairie and a variety of mixed and hardwood swamps. These wetlands 

 provide cover, forage, and nesting habitats for birds and other wildlife 

 species. Many crustaceans and fi sh are adapted to the transitional zone 

where freshwater and saltwater mix.

Most swamp-type wetlands are typically found along rivers, such as 

the Sebastian River. Prominent trees are red maple, cypress, and laurel 

oak. The largest area of swamp is Turnbull Hammock bordering Turnbull 

Creek. The swamp grades into upland hammock at the upper end of the 

watershed, but at its lower end it is typically blackwater fl oodplain forest or 

hydric hammock. 

There are several freshwater marshes in the basin, though most are 

small in size, less than fi ve acres (Woodward-Clyde Consultants et al., 

1994). Many of those close to the IRL lagoon system are in swales and 

depressions between dunes and dune ridges that extend in a linear northto-south direction. They are situated on sandy soils and receive water 

from either a high ground water table and by the lateral fl ow of water from 

dunes. The largest marsh of this type is in the Merritt Island National 

Wildlife Refuge. 

Wet prairies or fl atwood marshes are common wetland types characterized as typically round depressions within poorly drained pineland or 

fl atwood communities. In their natural state, these marshes were isolated 

from other wetlands and surface waters, but, subsequently, ditches constructed to provide drainage have connected them to the surface drainage 

system (Woodward-Clyde Consultants et al., 1994). This type of marsh 

can grade into pinelands through poorly drained cabbage palm savannas or 

wet prairies.

Seagrasses and Open Water

Submerged aquatic vegetation (SAV), including seagrasses and macroalgae, comprise an important community type within the IRL lagoon 

system. Figure 2.4 displays the distribution of seagrasses at different time 

periods. There are seven species of seagrass within the lagoon system, 

with the three most abundant species being turtle grass, manatee grass, 

and shoal grass. Factors that affect the distribution of SAVs include water 

38 Water Quality Assessment Report: Indian River Lagoon
Figure 2.4: Comparison of Seagrass Distribution in 1943, 1992, and 2003

Water Quality Assessment Report: Indian River Lagoon 39
depth and clarity as defi ned by the penetration of light, substrate, nutrient 

concentrations, salinity levels, water temperature, stormwater runoff, and 

water-based activities on and around the seagrasses. 

SAVs support the lagoon’s biodiversity in many ways. SAVs help to 

stabilize bottom sediments, reducing the resuspension of particulate matter 

and sediments and reducing turbidity in the water column. They also 

 provide cover for juvenile fi sh and wildlife and provide opportunities for 

foraging for food by larger predators. Communities of algae, small plants, 

and animals live within the SAVs and attach themselves to the seagrass, 

benthic invertebrates, and fi sh. SAV beds support a rich diversity of fi sh 

and other species and fi sh densities. Seagrasses are a major food source for 

the West Indian manatee. Juvenile sea turtles also forage on seagrasses. 

Seagrass coverage in the IRL lagoon system has declined in many areas 

since 1943 (Figure 2.4). Overall, seagrasses declined about 18 percent 

from the early 1940s to 1992 (Virnstein, 1999). Some areas of the lagoon 

system have lost very little seagrass; examples are the southern part of the 

Mosquito Lagoon, northern Banana River, and the north end of the IRL. 

Generally, seagrasses have done well in areas with limited development or 

near natural areas (wetlands and uplands). Other more developed areas 

of the lagoon system have had extensive losses of SAV. Between 1942 and 

1992, the stretch of the IRL from the NASA Causeway south to the city of 

Grant lost about 70 percent of its seagrass acreage (Virnstein, 1999).

Parts of the lagoon bottom that are not covered with SAV also provide 

important habitat. About 65 percent of the IRL lagoon system is open 

water (Woodward-Clyde Consultants et al., 1994). Bottom types can 

be rocky, sandy, or muddy. These bottom types provide important habitat for hard clams, oysters, and blue crabs. Phytoplankton adds to the 

seagrass-based productivity of the lagoon and is the base of its food web. 

Phytoplankton and zooplankton provide food for larval spotted sea trout 

and other economically important fi sh species and adult bay anchovy and 

black mullet.

Impounded Marshes

The impoundment of coastal marshes was begun in the 1930s as 

a mechanism to control salt marsh mosquitoes. Management of the 

impoundments was generally done by control of water levels during mosquito breeding season. Impounded marshes (about 75 percent of the 

wetland area of the IRL Basin) were disconnected from the open waters 

of the lagoon system, thereby prohibiting fi sh and other aquatic organisms from inhabiting the marshes. Marsh impoundment also prevents 

the transport of detritus to the lagoon system, limiting an important food 

source for some aquatic animals. Mangroves are frequently killed through 

impoundment, thereby removing roosting and rookery habitat for wading 

birds. Changes in community structure from marsh to mangrove wetland 

occurred in impoundments south of the city of Melbourne. 

Since the 1980s, some form of rotational impoundment management 

has been in effect. Rotational impoundment management allows alternating fl ooding and drying cycles. Open Marsh Water Management requires 

the installation of culverts or other openings allowing for more natural tidal 

cycles and fl uctuations (SJRWMD, 1996).

40 Water Quality Assessment Report: Indian River Lagoon
Spoil Islands

Spoil islands are created when sediment dredged from the bottom of 

the IRL is deposited to form large mounds or islands. Dredged sediments 

are composed of sand, shell, and muck. The construction and regular 

maintenance of the Intracoastal Waterway and other navigation channels 

has resulted in a number of spoil islands. Once created, spoil islands are 

rapidly colonized; unfortunately, most vegetation is exotic. Spoil islands 

do support a diverse assemblage of fi sh and wildlife. Seagrasses established 

around the perimeter of the islands increase their biological diversity and 

utility by providing habitat for juvenile fi sh and other aquatic species.

Important Plants and Animals

The IRL ecosystem contains more species of plants and animals than 

other similar ecosystems in North America. It is estimated to contain 

more than 2,200 animal species and 2,100 plant species. The eco system’s 

 location along the Atlantic fl yway contributes to its use by a diverse number 

of bird species. About 125 species of birds breed in the ecosystem while 

another 170 species winter there. At least 50 wading bird and shore bird 

mixed nesting areas are present; most are on spoil islands and within 

mangrove swamps (Woodward-Clyde Consultants et al., 1994). One of the 

larger rookery areas is Pelican Island in the Pelican Island National Wildlife 

Refuge. Gilmore (1995) has listed at least 782 species of fi sh from the eastcentral Florida region, including the IRL ecosystem. He noted that about 

half the listed species utilized the IRL lagoon system during at least part of 

their life cycle.

The high biodiversity of the IRL ecosystem is helped by its geographic 

position, stretching across temperate and subtropical climatic zones. 

Proximity to tropical ocean currents provides stable warm water temperatures with limited seasonal variation, which enhance biodiversity 

(Gilmore, 1995). 

The diversity of aquatic habitats is another factor adding to the diversity of resident and transient species. Some marine animals such as the 

West Indian manatee and bottlenose dolphin use the lagoon on a yearround basis. Other marine species use the lagoon seasonally or during 

migration to other feeding or refuge areas.

Rare, Imperiled, and Endangered Plants and Animals 

The Florida Natural Areas Inventory Database of Element Occurrences (2005) documents the occurrence of 44 state or federally threatened 

or endangered plant and animal species in the IRL Basin (Table B.2 in 

Appendix B). Merritt Island National Wildlife Refuge contains a large 

number of these threatened and endangered species. Development of the 

basin with subsequent loss of critical habitat has reduced the number of 

many of the identifi ed rare and imperiled species.

A number of bird species are listed species or considered imperiled. 

Pelican Island National Wildlife Refuge was created in 1890 to protect 

the endangered Eastern brown pelicans (Pelecanus occidentalis). A historic 

threat to the pelicans was the widespread use of chlorinated pesticides 

(primarily DDT) in the 1960s and 1970s, though the bird has largely 

Water Quality Assessment Report: Indian River Lagoon 41
recovered. A more recent issue is the entanglement of the birds in fi shermen’s lines. The dusky seaside sparrow was at one time an inhabitant of 

coastal marshes, but has become extinct most likely as a result of the construction of impoundments that altered its habitat. The Florida scrub jay 

(Aphelocoma coerulescens coerulescens) prefers dry, sandy oak scrub habitat, 

and although this habitat is also desirable for human development, this 

bird species is still present in the Merritt Island National Wildlife Refuge, 

Kennedy Space Center, Cape Canaveral Air Force Station, and at scattered 

locations in Brevard and Volusia Counties (Woodward-Clyde Consultants 

et al., 1994). 

Johnson’s seagrass (Halophila johnsonii) is a rare seagrass found from 

Sebastian Inlet south (SJRWMD, 1996). Listed as threatened at both the 

federal and state levels, Johnson’s seagrass is one of seven species of seagrass 

that grows in the IRL lagoon system. 

Several other rare or imperiled plant species occur in this basin. 

 Curtiss’ sandgrass (Calamovilfa curtissii), the sand butterfl y pea 

(Centrosema arencicola), sea lavender (Argusia gnaphalodes), and large-

 fl owered rosemary (Conradina grandifl ora) are examples of state-listed 

species. Curtiss’ sandgrass, the sand butterfl y pea, and large-fl owered 

 rosemary typically grow in scrub or sandhill habitats. Sea lavender is typically found near beaches, coastal strand, and the outer edge of salt fl ats. 

Development threatens much of these habitat types throughout the IRL 

Basin (NatureServe, 2005).

Several rare and imperiled fi sh species have been documented as 

occurring in the IRL lagoon system. Occurrences of the mangrove rivulus 

(Rivulus marmoratus), opossum pipefi sh (Microphis brachyurus), mountain 

mullet (Agonostomus monticola), and river goby (Awaous banana) have been 

documented in the lagoons (NatureServe, 2005). The mangrove rivulus 

and opossum pipefi sh are listed as species of special concern by the U.S. 

Fish and Wildlife Service (NatureServe, 2005). The mountain mullet has 

been observed in Crane Creek and Mosquito Lagoon, the opossum pipefi sh 

was recorded in Sebastian Creek, and the river goby was recorded in the 

Sebastian River, North Canal, and South Canal. 

The distribution of the mangrove rivulus parallels the distribution of 

red mangroves, and it is considered an indicator of red mangrove community health due to its sensitivity to habitat destruction and toxins (Taylor, 

Davis, and Turner, 1995). The mangrove rivulus has already disappeared 

from impounded coastal marshes in the IRL Basin (Taylor, Davis, and 

Turner, 1995). 

Two species of marine turtles, the green turtle (Chelonia mydas mydas) 

and loggerhead turtle (Caretta caretta), inhabit the IRL lagoon system. 

The green turtle is listed as endangered while the loggerhead turtle is listed 

as threatened at both federal and state levels. The lagoon system provides 

important habitat for both species in their early development stages. Both 

turtle species return to the ocean at reproductive maturity. Threats to their 

viability include collisions with boats and entanglement in fi shing lines. 

Many sea turtles are also infected with a disease known as fi bropapillomatosis, which causes tumor-like growths. 

42 Water Quality Assessment Report: Indian River Lagoon
The population of West Indian manatees that reside in the IRL 

lagoon system represents about one-third of the Florida population of 

manatees. During warm weather, manatees are present throughout the 

lagoon. During cooler weather, they congregate at warm water discharges 

from power plants, or they migrate south. Boat traffi c is a continual 

threat to manatees. Many are killed by boats or scarred from contact with 

 propellers. Brevard and Volusia Counties have completed and received 

approval for manatee protection plans from the FWC and the U.S. Fish 

and Wildlife Service.

The Atlantic bottlenose dolphin, though not a listed species, is prevalent in the central and southern parts of the IRL. There could be as many 

as 300 animals residing in the lagoon on a permanent basis while many 

other dolphins move between the lagoon and Atlantic Ocean. Collisions 

with boats and fi shing lines are threats to dolphin survival. Additionally, 

a fungal skin disease called Lobo mycosis affl icts as much as 12 percent 

of the dolphin population and is another threat to the local population 

(SJRWMD, 1996). 

Commercially and Recreationally Valuable Species

Spotted seatrout (Cynoscion nebulosus), common snook (Centropomus 

undecimalis), Atlantic tarpon (Megalops atlanticus), grouper and snapper 

(families Serranidae and Lutjanidae), hard clams (Mercenaria mercenaria), 

rock shrimp (Sicyonia brevirostris), white shrimp (Penaeus setiferus), oysters 

(Crassostrea virginica), blue crabs (Callinectes sapidus), red drum (Sciaenops 

ocellatus), and striped mullet (Mugil cephalus) are among the most commercially important and recreationally popular fi sh and shellfi sh in the IRL 

lagoon system. Commercial and recreational fi shing is a signifi cant source 

of local revenue. Preliminary 2005 commercial landings data collected 

through September 30, 2005, recorded more than 3.3 million pounds of 

fi sh and invertebrates (including species used for bait) from Brevard, Indian 

River, and Volusia Counties over which the IRL Basin spans (FWC, 2006). 

More than half the landing total was recorded from Brevard County.

Many fi sh species use the IRL lagoon system as a nursery. Adult fi sh 

such as tarpon, snapper, and grouper live off shore, but their larvae enter the 

lagoon system. Juvenile tarpon use mangrove marshes as a nursery (Sportfi sh Research Institute, 2006). Florida is the only location in the United 

States that tarpon use as a nursery (Sportfi sh Research Institute, 2006). 

Adult snook and red drum live in the IRL lagoon system but migrate to the 

inlets to spawn. Juvenile snook and red drum use mangrove marshes and 

seagrass beds, respectively, as nursery habitat. Mosquito impoundments 

also contain valuable habitat for juvenile fi sh. Much is unknown about the 

life history of fi sh species. Sportfi sh research efforts at the Florida Institute of Technology and the Florida Fish and Wildlife Research Institute 

(FWRI) are directed toward fi lling those gaps. 

Over the past 50 years there have been accounts of decreasing fi sh and 

shellfi sh populations in the IRL Basin, particularly snook and seatrout, 

documented by reduced landings, though further study and evaluation 

is needed. Changes in fi shing regulations account for some of the landings reduction. Total commercial landings data from 1959 to 1962 for the 

Water Quality Assessment Report: Indian River Lagoon 43
area from Ponce de Leon to Melbourne averaged about 6 million pounds 

(SJRWMD, 1996), almost twice the total for 2005. Upward trends in total 

landings in the 1970s through 1985 were attributed to increased harvest of 

hard clams (SJRWMD, 1996). Other threats specifi c to shellfi sh are the 

closures of shellfi sh beds due to high levels of coliform bacteria or reclassifi cation of beds as restricted or prohibited because of declines in water 

quality. There are fi shing accounts from the late 1800s and early twentieth 

century of large catches of snook, jewfi sh, and large sawfi sh. Sawfi sh and 

jewfi sh are no longer present in the IRL lagoon system. 

The spotted seatrout is a fi sh species that prefers estuarine environments and is usually associated with beds of SAV. Reported catch of 

spotted seatrout has declined since 1952. The 1988 spotted seatrout catch 

was only 40 percent of the catch recorded in the 1950s (Woodward-Clyde 

Consultants et al., 1994). 

The common snook is a state-listed threatened species. The FWC 

began stocking hatchery-raised red drum at several locations in the IRL 

lagoon system in 1999 (FWC, 2005). About 17 percent of the hatcheryraised red drum released were later caught by anglers (FWC, 2005). Starting in 1986, the state and federal governments enacted regulations that 

reduced the recreational harvest of red drum. Commercial harvest of red 

drum was banned in 1988. 

Biological Resource Issues

Biological threats within the IRL Basin generally fall into fi ve categories: fragmentation or loss of habitat, water quality decline, excess 

exploitation of resources, introduction of exotic species, and stressed and 

diseased fi sh and wildlife (SJRWMD, 1996). Continued urbanization 

of the basin has resulted in confl icting human/wildlife uses or in the loss 

of wildlife habitats. Impoundment of coastal marshes and losses or degradation of seagrass beds reduced suitable fi sh habitat. Urban expansion 

and discharges from agriculture in the IRL Basin have increased stormwater runoff to the lagoon system. Associated with stormwater runoff are 

 turbidity, nutrients, and other pollutants. The viability of SAV is reduced 

by increased turbidity in the water column due to the attenuation of light. 

The deposition of sediments causing turbidity can reduce the viability of 

benthic organisms. 

Exotic species are a constant threat to the biological integrity and 

 vitality of the communities within the IRL Basin. Many of the exotics are 

of West Indian or tropical origin. Australian pine (Casuarina equisetifolia)

was planted as a windbreak starting in the 1920s and formed extensive 

stands in upland hammock and forest areas south of Cape Canaveral. It is 

a fi re and temperature sensitive species and many trees were killed during 

freezes in the 1990s. In many places, Australian pine has been replaced 

by Brazilian pepper (Schinus terebinthefolius), another invasive and exotic 

plant species that has overrun both upland and wetland habitats. Brazilian pepper is salt tolerant and tends to invade mangrove communities 

that have been disturbed. Its seeds are dispersed by birds. This species 

was not common as recently as the 1950s, but has since become quite 

abundant (Alexander and Cook, 1974). Cajeput or Melaleuca (Melaleuca 

44 Water Quality Assessment Report: Indian River Lagoon
 quinquenervia) is another Australian import that has invaded large areas 

of south and central coastal Florida. Loss of fi re as an ecological control 

mechanism has also contributed to the expansion of invasive and exotic 

plant species. 

Since the completion of the IRL Comprehensive Conservation Management Plan in 1996, there have been several perplexing and disturbing 

episodes of wildlife-related disease and mortality in the IRL lagoon system. 

These events have raised concerns about the overall health of the estuary. 

The events noted over the past decade include

• The occurrence of a skin disease, Lobo mycosis, on many of the 

lagoon’s resident dolphins.

• Large numbers of green turtles with fi bropapilloma lesions. The 

 disease was fi rst noted in 1982, but has become more prevalent in 

recent years.

• An increase in the incidence of tumors in hard clams.

• A decrease in the number of horseshoe crabs. The horseshoe crab is 

an important food source for loggerhead turtles and also shorebirds. 

Numbers of horseshoe crabs have declined since the 1970s and 1980s 

(Provancha, 1999).

• The appearance of saxitoxin in pufferfi sh in the northern segments 

of the lagoon. Catching pufferfi sh has been banned, and health 

advisories regarding consumption of these fi sh have been issued by 

the Florida Department of Health (DOH) (DOH, 2005). Saxitoxin 

is typically found in shellfi sh and, when affl icted shellfi sh are eaten, 

can cause paralytic shellfi sh poisoning. Investigations by the FWRI 

determined that a native alga produced the toxin.

• The appearance of the Australian spotted jellyfi sh (Phyllorhiza 

 punctata) in the central lagoon area. These jellyfi sh were observed 

during summer months in 2001 and 2002, but not in 2003. This 

species eats large quantities of fi sh eggs, larvae, and microzooplankton. If it becomes a common inhabitant of the IRL lagoon system, it 

would have a negative impact on local fi sh populations. A volunteer 

monitoring program called Dockwatch has been organized to look 

for the Australian spotted jellyfi sh in the basin.

• The appearance of the exotic macroalga Caulerpa brachypus in the 

southern parts of the IRL lagoon system. It was fi rst observed in the 

spring of 2003 near Fort Pierce Inlet and St. Lucie Inlet, but has not 

been observed since that time. This alga originated in the Pacifi c 

Ocean with no known natural controls in Florida. Under certain 

conditions, it can cover submerged vegetation such as seagrasses and 

coral reefs, thus raising concerns over potential damage to seagrass 

beds if it ever became established in the IRL lagoon system. 

Water Quality Assessment Report: Indian River Lagoon 45
In an effort to address the above problems, the Indian River Lagoon 

Biotoxin and Aquatic Animal Health Task Force was created by the Indian 

River Lagoon National Estuary Program (IRLNEP) and the FWRI 

(SJRWMD, 2006c). In early 2006, the Task Force recommended three 

research projects for funding, which aimed at providing a better understanding of the relationship between observed aquatic animal health 

issues and possible effects of biotoxins. Projects include literature review 

to document historical events, epidemiological linkages between disease 

and exposure to saxitoxin, and monitoring phytoplankton populations to 

 determine their distribution (SJRWMD, 2006b). 

Ground Water Resources

Aquifers

Hydrologically, the eastern boundary of the IRL Basin is the Atlantic 

Ocean and the western boundary is the drainage divide formed by the 

Talbot Terrace (25 to 42 feet above mean sea level [MSL]) (Bermes, Leve, 

and Tarver, 1963). The terrace divides rainfall runoff into an easterly 

drainage toward coastal lagoons and the Atlantic Ocean and a westerly 

drainage toward the St. Johns River. 

The basin is covered by undifferentiated sediments of Pleistocene and 

Holocene ages that consist of sand and clay, dune sand, and coquina and 

shell debris near the coast. Together with some isolated peat deposits in 

the lakes and marshes, this layer of undifferentiated sediments comprises 

the surfi cial aquifer in the area. The surfi cial aquifer is unconfi ned and 

between 50 and 100 feet in thickness. In general, it is thicker in the southern part of the IRL Basin (Scott, Lloyd, and Maddox, 1991).

The surfi cial aquifer is underlain by interbedded lenses of marine, fi ne 

to medium sand, shell, and silty clay of Pliocene and Upper Miocene ages 

that lie on top of a confi ning layer, the Hawthorn Formation of Miocene 

age. The Hawthorn Formation consists of plastic, phosphatic, sandy clay, 

and marl interbedded with lenses of phosphorite pebbles, phosphatic sand, 

and phosphatic sandy limestone (Bermes et al., 1963). The Hawthorn Formation is from 50 to 200 feet in thickness in the basin (Scott et al., 1991). 

The intermediate aquifer is confi ned and consists of more permeable lenses 

of sand, shell, and limestone that occur within the confi ning layer. This 

aquifer is a locally important water source.

The Floridan aquifer system, which is confi ned, lies beneath the Hawthorn Formation. In the IRL Basin, the Floridan aquifer consists of a series 

of limestone formations of Eocene age; in descending order, these include 

the Crystal River Formation, Williston Formation, Inglis Formation, Avon 

Park Limestone, and Lake City Limestone (Bermes et al., 1963). The top 

of the Floridan aquifer is located between 100 and 400 feet below MSL, 

with a thickness of approximately 2,000 feet. The Floridan aquifer is 

under artesian pressure (Scott et al., 1991), and wells completed in the Floridan aquifer can fl ow if they are not capped. There are also fl owing springs 

offshore in the Atlantic Ocean that discharge from the Floridan aquifer.

46 Water Quality Assessment Report: Indian River Lagoon
Ground Water–Surface Water Interactions 

Precipitation in the IRL Basin runs off to the Atlantic Ocean, to the 

IRL lagoon system (Intracoastal Waterway) between the barrier islands and 

the mainland, or to streams, canals, wetlands, lakes, and ponds. It also 

infi ltrates to recharge the surfi cial aquifer and, in turn, part of the intermediate aquifer.

The IRL Basin is a discharge area for the artesian Floridan aquifer. 

The potentiometric surface of the Floridan aquifer ranges from 0 to 35 feet 

above MSL along the coastline. The amounts of upward fl ux through 

seepage, springs, sinks, or unplugged wells to the surfi cial and intermediate aquifers and to surface waters (including points offshore beneath the 

Atlantic Ocean) depend on the thickness and the extent of breaching of 

the overlying confi ning layer. The surface water in the basin could be a 

mixture of direct precipitation, surface runoff, seepage from the surfi cial 

aquifer, and discharge from the Floridan aquifer. In the near-coastal areas 

and in the vicinity of canals that do not have salinity control structures, 

saltwater intrusion into the surfi cial aquifer occurs.

Ground Water Usage

Both the surficial and Floridan aquifers are signifi cant sources of water 

for public supply, agriculture, and industrial uses, although surface water 

is also relied on. The intermediate aquifer is used to a lesser extent but 

can be a locally important water source. The Floridan aquifer, because of 

its depth and location in the IRL Basin, contains brackish water. In this 

area, water drawn from the Floridan aquifer may be blended with water 

drawn from the surfi cial aquifer or surface waterbodies as drinking water 

supply. According to the Department’s Public Water System database, 

there are 269 public supply wells in the basin that provide water for potable 

supply, 141 of which provide water to communities. The city of Vero 

Beach (34 wells), the city of Palm Bay (27 wells), and the city of Titusville 

(17 wells) have the largest number of public supply wells in the basin. The 

Vero Beach wells all draw water from the Floridan aquifer; Palm Bay and 

Titusville wells draw from the surfi cial aquifer. Figure 2.5 shows public 

supply wells in the basin.

Ground Water Quality Issues

A well-known and significant ground water quality issue in the IRL 

Basin is the naturally occurring high content of sodium and chloride in the 

Floridan aquifer and to a lesser extent in the intermediate aquifer. This is 

due to the natural setting of the coastal basin and the underlying aquifers. 

Ground water is artesian, with a high yield in the Floridan aquifer. However, the upper Floridan aquifer, especially its deeper part and at locations 

closer to the coast, may contain up to 3,000 milligrams per liter or more of 

chloride. This situation is further aggravated by the increasing pumpage of 

water supply wells associated with the basin’s growing population and agricultural and industrial activities. The vertical upwelling of high chloride–

high sodium water induced by pumping wells is a signifi cant problem for 

public water supplies in the basin. In some cases, water withdrawn from 

the Floridan aquifer must undergo membrane treatment and be blended 

Water Quality Assessment Report: Indian River Lagoon 47
with water from the surfi cial aquifer before it can be used as public water 

supply or agricultural water supply.

Another issue pertains to the use of the Floridan aquifer as a source 

of irrigation water for citrus groves in the basin. In addition to the other 

problems caused by overproduction, the high-salinity water is infi ltrating into the surfi cial aquifer and being discharged to canals. This results 

in potential localized impacts to the surfi cial aquifer and fresh surface 

 waterbodies.

Ground water quality in the IRL Basin is affected in some areas by 

contaminant sources; these are being addressed by several programs managed by the Department and a number of sites or facilities are included in 

Department databases. Figure 2.5 shows the known sources of contamination in the IRL Basin. These include the following: 

1. Federal Superfund Sites:

 There are two Superfund sites on the National Priority List in the 

basin, as follows:

 Harris Corporation Superfund Site, Palm Bay: This 300-acre 

electronics manufacturing facility site is associated with a plume 

of volatile organics that affected the adjacent wellfi eld owned by 

Palm Bay Utilities. Palm Bay Utilities provides drinking water to 

approximately 33,000 Palm Bay residents. The site is currently 

under remediation, which involves ground water extraction and 

treatment. 

 Piper Aviation Superfund Site, Vero Beach: This small site adjacent to the Vero Beach Municipal Airport is associated with soil 

and ground water contamination by volatile organics and the contamination of a city of Vero Beach municipal supply well. Ground 

water extraction and treatment are currently ongoing. 

2. State-funded Waste Cleanup Program Sites: 

 There are three State-funded Waste Cleanup Program sites in the 

basin: the Cocoa Beach Gasoline Contamination cleanup site, 

the Weekley Lumber wood preserving waste site, and the Skippers 

electroplater’s cleanup site.

3. Petroleum Contamination Monitoring Sites:

 There are more than 900 known petroleum contamination monitoring sites in the basin. These sites are undergoing ground water 

monitoring, and some of them are undergoing cleanup. Public or 

private drinking water supplies affected by petroleum contamination will be protected in one of several ways: by decommissioning 

the affected well and providing water from an alternative source, by 

providing treatment at the water plant, or, for affected residential 

wells, by installing activated carbon fi lters to remove the contamination and meet drinking water standards.

4. State Dry Cleaning Program Sites:

 About 35 dry cleaning program sites have been identifi ed in the 

basin. All of them are located in cities such as New Smyrna Beach, 

48 Water Quality Assessment Report: Indian River Lagoon
Figure 2.5: Public Supply Wells and Potential Sources of Contamination in the Indian River 

Lagoon Basin

Water Quality Assessment Report: Indian River Lagoon 49
Titusville, Cocoa Beach, Merritt Island, Melbourne, and Vero 

Beach. Affected water supplies will be addressed as described for 

petroleum facilities.

5. Delineated Ground Water Contamination Area (not depicted 

in Figure 2.5):

 One delineated ground water contamination area is present in 

the basin and is located in Palm Bay in Brevard County. Ground 

water at the site contains metals and volatile organic compounds in 

concentrations that exceed ground water standards.

Priority Water Resource Caution Areas 

Parts of the IRL Basin are in a Priority Water Resource Caution Area 

(PWRCA) designated by the SJRWMD. The parts of the basin included 

in the PWRCA designation are depicted in Figure 2.6 and generally 

include south Volusia County, north Brevard County, and Brevard County 

beach communities. 

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

each water management district in the state must identify PWRCAs 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 PWRCAs:

• 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.

Watershed Management Activities and 

Processes

Over the years, management plans and activities in the IRL 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. Table 2.3 provides a summary of water quality issues 

that confront the basin.

Much of the progress in the IRL Basin in developing water quality 

restoration plans and implementing watershed and water quality improvements is attributable to coordinated local, state, and regional efforts. Many 

50 Water Quality Assessment Report: Indian River Lagoon
Figure 2.6: Priority Water Resource Caution Areas within the Indian River Lagoon Basin

Water Quality Assessment Report: Indian River Lagoon 51
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.

Pollutant Load Reduction Goals

Pollutant Load Reduction Goals (PLRGs) are defined as “estimated 

numeric reductions in pollutant loadings needed to preserve or restore ... 

receiving bodies of water ...” (Chapter 62-40.210[20] F.A.C.). The state 

of Florida has directed its water management districts to establish PLRGs 

as part of a Surface Water Improvement and Management (SWIM) plan or 

other plans, or as a basin rule (SJRWMD, 2006a). A preliminary PLRG 

has been developed by the SJRWMD for the IRL lagoon system that targets the restoration and enhancement of seagrass beds in the lagoon. Seagrass is a critical habitat for fi sh and other marine and estuarine organisms. 

The most important factor infl uencing seagrass growth, abundance, 

and depth distribution is the amount of light that reaches the grass bed 

(as referenced in Steward and Green, 2006; Morris, Virnstein, and Miller, 

2002). Water clarity is the primary indicator of light availability and 

controls the depth to which light will penetrate the water column. Water 

quality factors that infl uence water clarity are turbidity caused by total 

suspended solids (TSS) loading, sediment resuspension, phytoplankton 

Table 2.3: Summary of Water Quality and Habitat Issues in the 

Indian River Lagoon Basin

Habitat Loss and Habitat Change

• Loss of seagrass beds

• Loss of fishery resources

• Isolation of salt marsh and mangrove habitat by mosquito 

impoundments

• Stresses to environmentally sensitive species

Water and Sediment Quality

• Increased fresh water discharges and changes in timing because of 

changes to drainage patterns

• Changes in circulation and flushing because of channel dredging, inlet 

stabilization, and causeway construction

• Fluctuations in salinity at tributary stream mouths from release of too 

much fresh water 

• Nutrient loading from stormwater runoff

• Increased levels of bacteria and pathogens

• Increased levels of suspended particles

• Increased levels of toxic substances and contaminated sediments

• Formation of muck bottom in numerous areas, particularly at the mouth 

of tributaries 

• Impacts of increased boating by resuspension of bottom sediments and 

shoreline erosion

52 Water Quality Assessment Report: Indian River Lagoon
densities, and water color. Nutrient over-enrichment in the lagoon can 

trigger excessive growth of phytoplankton, which can successfully compete 

against seagrass and other macrophytes for available light. The pollutants 

of concern to seagrasses, and for which the PLRG was developed, were 

therefore nutrients (total nitrogen and total phosphorus, which fuel phytoplankton growth) and TSS.

Seagrass restoration targets were established for the IRL and Banana 

River Lagoon (Steward and Green, 2006). Mosquito Lagoon was not 

included in the PLRG developed for the IRL lagoon system because 

change of seagrass coverage in the lagoon was not suffi cient to identify the 

 causative pollutant. A description of the PLRG development process for 

the IRL lagoon system is provided in the Seagrass Assessment section of 

Chapter 3. 

Relationship between Pollutant Load Reduction Goals and Total 

Maximum Daily Loads

Several segments of the IRL and Banana River were listed on the 1998 

303(d) list and required development of TMDLs. The U.S. Environmental 

Protection Agency (EPA) proposed TMDLs for 18 segments for nutrients, 

chlorophyll a, and dissolved oxygen on June 30, 2003 (EPA, 2007a). The 

EPA used the established provisional PLRGs (estimated 1943 watershed 

loads corresponding to the seagrass benchmark year of 1943) as the basis 

for calculation of TMDL loading targets. EPA fi nalized its TMDLs in 

April 2007, based on the PLRG updated by the SJRWMD in March 2006 

(Steward and Green, 2006). 

Major Programs, Plans, and Projects that Protect and Improve Water 

Quality and Biological Resources

There are several layers of resource management and protection 

afforded to the IRL Basin across federal, state, and local jurisdictions. The 

IRL is a designated SWIM Priority Water and a National Estuary. 

A number of major restoration initiatives and water quality improvement projects will have signifi cant positive effects on the basin’s water quality if continued. More information about individual current projects under 

way is listed in Appendix C.

Indian River Lagoon Act

Passed in 1990 by the Florida legislature, the Indian River Lagoon 

Act (IRL Act), also known as Chapter 90-262, Laws of Florida, required 

that domestic wastewater treatment plants stop discharging into the IRL 

lagoon system by April 1, 1996. Before 1995, domestic wastewater treatment plants contributed 15–20 percent of the nutrient loading of the lagoon 

system. For some segments that loading was substantially higher, as much 

as 70 percent of the nutrient loading. Other than occasional wet weather 

discharges and other discharges allowed under subsequent legislation, 

domestic wastewater in the basin has been substantially reduced. Cape 

Canaveral, Edgewater, and New Smyrna Beach, in addition to providing 

wastewater for reuse, continue to discharge a portion of their wastewater to 

the lagoon system, though each community is working to reduce or cease 

discharge (Steward, 2006). Currently, domestic wastewater discharges 

Water Quality Assessment Report: Indian River Lagoon 53
contribute less than 2 percent of nutrient loading to the lagoon system 

(Steward et al., 2003).

The IRL Act also required that package wastewater treatment plants 

be evaluated for their potential threat to the water quality of the IRL 

lagoon system. Many package plants have been connected to larger wastewater treatment plants and are now out of service. Some, however, are 

 outside the service area of larger domestic wastewater plants and remain 

in operation.

Surface Water Improvement and Management Priority Waters

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

waterbodies. The IRL was designated a SWIM waterbody in 1987 as 

part of the legislative act creating the SWIM Program. The fi rst SWIM 

plan was prepared and approved in 1989 with subsequent updates in 1994 

and 2002. 

Three major SWIM goals were identifi ed for the IRL and its 

 watershed. They include

• Attain and maintain water and sediment quality that will support a 

healthy macrophyte-based estuarine lagoon ecosystem;

• Attain and maintain a functioning macrophyte-based ecosystem that 

supports endangered and threatened species, fi sh, and wildlife; and

• Heighten public awareness and coordinate interagency management 

of the IRL watershed. 

The initial SWIM legislation identifi ed 5 other priority waterbodies 

in addition to the IRL: Lake Apopka, Tampa Bay, Biscayne Bay, Lower 

St. Johns River, and Lake Okeechobee. Today, the program has expanded 

to include SWIM waterbody designation for 31 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.

Indian River Lagoon National Estuary Program

The IRLNEP was established in 1990. The SJRWMD was selected 

as the program sponsor responsible for providing staff support and local 

administration of federal funds. A Comprehensive Conservation and Management Plan (CCMP) for the IRL was completed in 1996 and updated 

in 2007 (SJRWMD, 1996; SJRWMD, 2008). The IRLNEP was built 

on the goals and objectives of the IRL SWIM Program outlined above 

with an additional fourth goal of long-term commitment to implementing 

the CCMP. 

One of the primary responsibilities of the IRLNEP is to foster active 

participation of other governmental entities and community members. 

Since 1994, the IRLNEP has assumed sole responsibility for public 

54 Water Quality Assessment Report: Indian River Lagoon
 involvement and education activities. The IRLNEP manages a local 

government cost share program targeted at small-scale projects, typically stormwater retrofi ts and improvements. The program is able to raise 

revenue for habitat restoration, water quality improvement, and education 

programs through the sale of a specialty license plate. 

National Park and National Wildlife Refuges

About half of the wetlands and a large portion of the open water and 

uplands in the IRL Basin are under the jurisdiction of the National Park 

Service and the U.S. Fish and Wildlife Service. Federally managed lands 

are listed in Table 2.4. The National Park Service completed revision 

of the Canaveral National Seashore Water Resource Management Plan 

in 2001 (Steward et al., 2003). The plan directs water-related management and public use activities for a 5- to 10-year period. The U.S. Fish 

and Wildlife Service has resource management responsibility over close to 

150,000 acres of national wildlife refuges. Refuge comprehensive conservation plans are developed for each refuge to outline water and land management within the refuge. Plans are revised every 15 years. 

Indian River Lagoon North Feasibility Study

The U.S. Army Corps of Engineers (USACOE) has initiated feasibility studies with the intent of evaluating and designing restoration projects 

for the northern and southern parts of the IRL. The USACOE’s activity is 

part of the overall Comprehensive Everglades Restoration Plan in response 

to the impacts of environmentally undesirable effects of fl ood control and 

drainage improvement done between the late 1940s and early 1980s. The 

major fl ood control project, the C&SF Project, has resulted in the diversion of large quantities of water from the Upper St. Johns Basin to the IRL 

lagoon system. 

The IRL North Feasibility Study began in 2002 and was reinitiated in 

2007. It includes parts of the basin located in Volusia, Brevard, and Indian 

River Counties. The SJRWMD is the local sponsor and cooperator with 

the USACOE on the study and has a role in the review and recommendation of improvement projects. The feasibility study is anticipated to be 

completed in 2008 and submitted to the U.S. Congress for authorization 

and funding approval in 2009 as part of the reauthorization of the Water 

Resources Development Act.

The feasibility study has incorporated the goals and objectives of the 

IRL CCMP and the IRL SWIM Plan. Potential projects include muck 

removal from canals or the Intracoastal Waterway and drainage infrastructure improvements.

Special Districts and Florida Inland Navigation District

There are three different types of special taxing districts in the basin: 

water control district, navigation district, and mosquito control district. 

Also known as Chapter 298 drainage districts, water control districts are 

special taxing entities that were created in 1916 by the Florida legislature to 

promote agriculture. There are fi ve active water control districts in the IRL 

Basin: Melbourne–Tillman, Fellsmere, Vero Lakes, Sebastian River, and 

Indian River Farms. The water control districts constructed and continue 

to maintain networks of drainage canals built largely to drain land for agricultural production. Water control districts are partners with SJRWMD, 

SFWMD, and USACOE in developing techniques to reduce the quantity 

and improve the quality of stormwater discharges.

Florida Inland Navigation District (FIND) was created in 1927 by an 

act of the Florida legislature. The creation of FIND was spurred by passage 

of the 1927 River and Harbor Act by the U.S. Congress, which authorized 

the establishment and maintenance of an inland waterway starting in Jacksonville (FIND, 2005). FIND is Florida’s sponsor for maintenance dredging of the Intracoastal Waterway along Florida’s coast. The responsibilities 

of FIND include developing dredging plans, acquiring and preparing sites 

for dredge spoil, and generally engaging in activities that enhance navigation. FIND is partnering with SJRWMD, SFWMD, and USACOE to 

provide cost sharing and technical assistance with muck removal projects.

Mosquito control districts were created by the Florida legislature 

with the specifi c responsibility of mosquito abatement. Responsibility for 

mosquito abatement in the IRL Basin rests with Volusia County Mosquito 

Control, Indian River Mosquito Control District, and Brevard County 

Mosquito Control. For more information, see http:// www.fl orida

mosquito.org/index_mosqinfo.html.

The Indian River Mosquito Control District was the fi rst district 

created in Florida with a founding year of 1926. A large part of the basin 

would be uninhabitable without mosquito control. Prior to the 1950s, 

control methods were based on ditching and draining of wetlands and 

spraying. Starting in the 1950s, the management technique of impounding 

coastal marshes for mosquito control was introduced. This technique takes 

advantage of a unique biological feature of the salt marsh mosquito (Saltmarsh Mosquito Control, 2007). This mosquito species will not lay eggs 

directly on water. From the 1950s to the 1970s, close to 75 percent of the 

coastal wetlands in the IRL Basin were impounded for mosquito control 

(Steward et al., 2003). 

Indian River Lagoon Blueway Program

The Indian River Lagoon Blueway Program is a purchase program 

for environmentally sensitive or critical lands. It is loosely based on the 

greenways concept of connecting critical habitats or sensitive lands through 

56 Water Quality Assessment Report: Indian River Lagoon
upland corridors; however, in the case of a blueway, such lands are accessible and connected by water. The Blueway Program is a partnership 

between the SJRWMD, SFWMD, county governments, the Department, 

and The Nature Conservancy. The program has identifi ed over 8,000 acres 

in about 600 parcels for purchase. Much of the lands identifi ed for acquisition are wetlands and their associated uplands.

Urban Stormwater Management

Stormwater generated in urban areas is managed through the National 

Pollutant Discharge Elimination System municipal separate storm sewer 

system (MS4) permitting program. The counties, military installations, 

and a number of local governments are included in Phase 2 of the MS4 

program. Governments with Phase 2 MS4 permits are listed in Table 2.5. 

Phase 2 MS4 permits address six distinct program areas. Two important 

MS4 program areas are the detection and remediation of illicit connections 

(nonstormwater) to the storm sewer system and pollution prevention public 

education.

Water Quality Assessment Report: Indian River Lagoon 57
Numerous local governments have enacted stormwater utilities to 

help pay for stormwater management and remediation activities. These 

municipalities are listed in Table 2.6 along with the rate of their stormwater utility fee. The equivalent residential unit is the standardized area of 

impervious surface assigned to one residential unit. Commercial development rates are based on the amount of impervious area compared to the 

standard residential area and rate.

Brevard County instituted its stormwater utility in 1990. The county 

has funded approximately $20 million in stormwater improvement projects 

since its inception (Powers, 2006). Brevard County has completed stormwater management plans for the Eau Gallie River and Crane Creek Basins. 

The Crane Creek plan includes Melbourne, West Melbourne, and unincorporated Brevard County. 

Malabar and West Melbourne joined the Brevard County stormwater 

utility in 2000 and 1999, respectively (Brevard County Stormwater Utility 

Department, 2005a). Brevard County acts as the administrator of the 

utility. Brevard County’s Stormwater Utility Department developed and 

implemented a Stormwater Utility Assessment Credit program for properties that are serviced by approved and maintained stormwater treatment 

systems (Brevard County Stormwater Utility Department, 2005b). The 

credit program provides for reductions in stormwater assessments for different degrees of landowner implemented and maintained stormwater treatment. A compliance inspection of the private treatment system is part of 

the overall credit program.

Cocoa Beach Green Business

The city of Cocoa Beach initiated a pilot Green Businesses Program in 

2004 in which local businesses agreed to follow best management practices 

(BMPs) designed to prevent pollution. In exchange, the businesses are 

 promoted to the public as green businesses. Restaurants, paint and 

masonry contractors, and lawn services are the target industries included in 

the pilot project. 

Florida Department of Environmental Protection Clean Marina, Clean 

Boatyard, and Clean Boater Programs

The Clean Vessel Act of 1994 prohibited boaters from discharging raw 

sewage into either freshwaters or coastal saltwaters within state jurisdiction 

(Section 327.53[4][a], F.S.) (Department, 2006a). For Florida’s Atlantic 

Coast, jurisdiction extends offshore to three nautical miles. The Clean 

Vessel Act Program was undertaken to provide strategies for construction and repair of boat sewage pump outs at marinas. The Clean Marina, 

Clean Boatyard, and Clean Boater Programs were a natural extension of the 

Clean Vessel Act Program needed to address a broader agenda of issues and 

concerns faced by marina and boatyard owners beyond the pump out of 

wastewater. 

The Clean Marina and Clean Boatyard Programs focus on owners and 

operators of facilities that support the boating community either by slip 

rental or repair and construction services. The Clean Boating Partnership 

oversees the development and implementation of these programs. The 

partnership is an alliance comprising the Department’s Division of Law 

Enforcement, Marine Industry of Florida, Florida Sea Grant Program, 

U.S. Coast Guard, International Marina Institute, and representatives of 

municipal and privately owned marinas. Facilities can become designated 

as a Clean Marina or Clean Boatyard by following a detailed checklist of 

clean boating BMPs developed for the industry and current regulations. 

The partnership provides workshops for the marine industry. To receive 

designation as a Clean Marina or Clean Boatyard, a facility is subjected to 

a walk-through inspection and verifi cation of its checklist by members of 

the partnership and staff from the Department’s Central District Offi ce. 

The marina or boatyard receives a plaque and fl ag to fl y over the facility 

and is also identifi ed as a Clean Marina or Clean Boatyard on the Department’s Web site and in industry service directories (Department, 2006b). 

 Currently, there are 11 certifi ed Clean Marinas/Clean Boatyards in the IRL 

Basin (Department, 2005f). There are at least 26 marinas in the basin that 

provide sewage pump-out services (Department, 2005f).

The Clean Boater Program focuses on the recreational boater through 

educational materials. Boaters are asked to take a “Clean Boater Pledge” 

and receive the Clean Boating Habits booklet (containing recommended 

BMPs or individual actions for boating safety, storm preparedness, pollution reduction, and aquatic plant and animal life protection), Clean Boater 

Sticker for their boat, and other shipboard items that serve as prompts for 

clean boater behavior (Department, 2006b).

Water Quality Assessment Report: Indian River Lagoon 59
Agricultural Best Management Practices

The Florida Watershed Restoration Act authorizes the Florida Department of Agriculture and Consumer Services (DACS) to develop interim 

measures and agricultural 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 (IFAS), 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. For example, Brevard County provides 

a 100 percent stormwater assessment credit to agricultural entities who 

implement a National Resource Conservation Service plan that includes 

BMPs and other activities to address runoff from agricultural properties 

(Powers, 2006). 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.

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. BMP 

manuals pertinent to the IRL Basin include the following:

• Guide for Producing Container-Grown Plants: This manual, 

published in 1995 by the Southern Nurserymen’s Association, 

includes irrigation and fertilization BMPs for the container cultivation of nursery plants. It was produced through a cooperative effort 

between the University of Florida, Auburn University, Tennessee 

Tech University, and Virginia Tech. Because the manual is not 

Florida-specifi c, an effort is currently under way to use the document 

in developing a Florida-specifi c manual.

60 Water Quality Assessment Report: Indian River Lagoon
• Best Management Practices for Agrichemical Handling and 

Farm Equipment Maintenance: Recently revised and reprinted, 

this manual gives producers guidance on hazardous materials, proper 

pesticide handling, and the proper disposal of waste products. It 

was cooperatively produced in 1998 by DACS, the Department, and 

several industry associations.

• Water Quality Best Management Practices for Cow/Calf Operations: Many cattle operators statewide have been trained in using 

this manual and are applying BMPs. The Florida Cattlemen’s 

Association and several state, federal, and local agencies developed 

the manual, which was published in 1999. Copies were printed and 

distributed in 2000 using EPA Section 319 grant funds.

• Water Quality/Quantity Best Management Practices for Indian 

River Area Citrus Groves: The regional BMPs in this manual 

apply to all or parts of the east coast counties in which the IRL Basin 

lies (Volusia, Brevard, and Indian River Counties). The Indian River 

Citrus League led a cooperative effort involving 15 agencies and 

industry associations in developing these BMPs. Beginning in 2000, 

the BMP manual and guidance booklets were published using EPA 

Section 319 and industry funds. IFAS has evaluated BMP compliance for DACS on 3,302 acres in Brevard County and 48,712 acres 

in Indian River County (Boman, 2005). These acreages include 

both the IRL and the Upper St. Johns Basins. Since the evaluations 

were performed, large areas of citrus have been lost as a result of 

 hurricane damage, urbanization, and canker.

• Aquaculture Best Management Practices: As directed by the 

1998 Florida legislature, DACS worked cooperatively with industry, state agencies, and the environmental community to develop a 

comprehensive BMP manual for aquaculture. Florida law requires 

that the Department adopt the manual by rule and provides regulatory exemptions under Chapters 373 and 403, F.S., for growers who 

implement BMPs and are certifi ed by DACS’ Division of Aquaculture. The manual, which was printed and distributed in 2000, has 

been adopted by rule.

• Florida Green Industries Best Management Practices for Protection of Water Resources in Florida: This manual provides BMPs 

for professional turfgrass and landscape managers. Published in 

2002, it was developed through a cooperative effort by Florida Green 

Industries (an industry association); the Department; DACS; the 

Florida Department of Community Affairs; and the St. Johns, South 

Florida, and Southwest Florida Water Management Districts.

• Rule-Based Initiatives: Under Chapter 576, F.S., in 2002 DACS 

adopted citrus BMPs by rule for the Lake Wales Ridge region, and in 

1996 adopted BMPs by rule for leatherleaf fern production areas in 

and around Volusia County.

Working Groups and Nongovernmental Organizations

Intergovernmental working groups and volunteer citizen groups play an 

important role in the restoration and enhancement of the IRL Basin. The 

partnerships created between government, nongovernmental organizations, 

and private citizens have provided numerous opportunities for restoration 

and protection of the IRL Basin.

Friends of Turkey Creek

The Friends of Turkey Creek is a volunteer group comprising homeowners along Turkey Creek. The group is directed by a six-member 

advisory board. The group’s interest is to maintain the navigability of the 

creek while also protecting its ecological value as fi sh and wildlife habitat. 

Sedimentation in the creek is a continual problem. The group plays an 

active role in seeking funding for the C-1 rediversion project.

Marine Resources Council

The Marine Resources Council (MRC) was founded as a volunteer 

organization over 15 years ago. This organization focuses on problems that 

impact the IRL lagoon system. Important issues of concern to the MRC 

are loss of seagrasses; negative impact of stormwater runoff on the lagoon; 

coordination of local, state, and federal programs for the lagoon; and the 

need for public input to better inform elected offi cials. 

The MRC is directed by a board of directors supported by staff. The 

MRC is currently involved with the IRL Greenway Committee, Indian 

River Lagoonwatch volunteer water quality monitoring program, and 

hosts “State of the Indian River Lagoon” public education workshops on 

a variety of timely topics. Past public education workshops have included 

topics such as septic tank problems, manatee plans, impacts of port development, and the Everglades restudy (Marine Resources Council of East 

Florida, 2005). 

Brevard and Indian River Counties Stormwater Working Group

Organized and managed by the SJRWMD, this group comprises local 

government and water control district stormwater managers and staff. The 

working group provides a forum for exchange of technical information 

about stormwater management issues and techniques and coordination of 

funding proposals for stormwater projects.

Friends of the St. Sebastian River

The Friends of the St. Sebastian River is a nongovernmental nonprofi t 

organization governed by an independent elected board (http://home.

comcast.net/~fssr/). Its goals are to promote and protect environmental 

and recreational opportunities, improve water quality, promote safe boating practices, protect wildlife by supporting manatee protection, promote 

public education and awareness, and encourage conservation of the Sebastian River. The group accomplishes its goals through cooperation and 

 participation with governmental agencies and other organizations that 

protect the Sebastian River. 

62 Water Quality Assessment Report: Indian River Lagoon
Environmental Learning Center

The Environmental Learning Center is a private nonprofi t organization located on Wabasso Island in Indian River County (http://www 

.elcweb.org/). The primary goal of the Center is to provide residents with 

an understanding of the natural world and to motivate them to protect it. 

About 80 percent of the Center’s activities are funded by membership fees, 

private donations, and fund-raising events. 

Brevard Nature Alliance, Inc.

The Brevard Nature Alliance, Inc., sponsors and promotes the development of nature-based education and activities throughout Brevard County 

(http://www.natureandspace.com). The Alliance is a nonprofi t organization that acts as a central agency for analyzing area natural resources and 

physical needs to help develop long-range plans for Brevard County. The 

Alliance can provide expertise and guidance for local governments and 

nongovernmental organizations in the expenditure of funds for community 

environmental development. 

Natural Resource Protection and Water Quality Improvement 

Projects Overview

C-1 Rediversion Project

The purpose of this project is to divert the discharge from the 

 Melbourne–Tillman Water Control District’s C-1 Canal westward toward 

the Upper St. Johns River Basin. The canal was built to drain marshes 

in the Upper St. Johns River Basin, creating suitable land for agriculture. 

Discharges through the canal into Turkey Creek could reach 500 million 

gallons per day after storms (Steward et al., 2003). The increased volumes 

of freshwater discharged through Turkey Creek to the IRL caused a lowering of salinity in the lagoon, added large loads of nutrients and sediments to 

it, contributed to the decline of the hard clam fi shery, caused fi sh kills, and 

reduced the area of seagrasses at the mouth of Turkey Creek. The larger 

volumes of water fl ushed through Turkey Creek have caused the erosion of 

the creek’s banks, sedimentation, and damage to wildlife habitat along the 

creek bank. 

The C-1 rediversion project is a Section 206 project jointly funded 

by the Melbourne–Tillman Water Control District, SJRWMD, and 

USACOE. Project plans require the construction of a spillway in the C-1 

Canal to divert stormwater west to the C-1 Retention and C-1 Detention 

Areas. Water will be returned from the C-1 Retention and Detention 

Areas to the Sawgrass Lake Water Management Area for additional water 

quality treatment before discharge to the St. Johns River. Construction 

of the C-1 Retention and Detention Areas and the Sawgrass Lake Water 

Management Area will result in the creation of 4,000 acres of wetland in 

the Upper St. Johns River Basin. The project is expected to help Turkey 

Creek and the IRL meet PLRGs for nutrient and suspended solids reductions (Steward et al., 2003). Other expected benefi ts of the project are the 

recovery of 280 acres of seagrass beds, recovery of as much as 3,000 acres 

of shellfi sh beds, and the reduction of the erosion of Turkey Creek’s bank. 

The tentative time frame for project completion is 2008. Because of federal 

Water Quality Assessment Report: Indian River Lagoon 63
 budgetary concerns, the SJRWMD has made a commitment to move forward with project design and construction (Steward, 2006).

Sebastian River Watershed

The Sebastian River is the largest tributary to the IRL lagoon system. 

It also provides some of the largest loadings of suspended solids and 

nutrients. Several projects, in addition to dredging of muck from the 

Sebastian River, are planned in this river basin for improved fl ood control, 

salinity maintenance, and reductions in loads of nutrients and suspended 

solids. The city of Sebastian has prepared a surface water master plan 

that addresses pollutant reduction and fl ood control. Parts of the plan 

include the construction of a dam on the Elkam Canal and a stormwater 

treatment pond that treats Stonecrop drainage. SJRWMD is completing 

construction of a stormwater treatment park in the southern part of the city 

of Sebastian (Steward, 2006). Within the North Prong Sebastian River 

drainage, 496 acres have been set aside for a stormwater treatment area 

near Sottile Canal to treat runoff from projected build-out of Barefoot Bay 

and for dredge spoil disposal. Plans are in progress between SJRWMD, 

USACOE, Sebastian River Water Control District, and Fellsmere Water 

Control District to address stormwater management and erosion control 

(Steward et al., 2003).

Indian River Farms Water Control District

Discharges from the Indian River Farms Water Control District, 

 delivered through North, Main, and South Canals, impacts about 12 miles 

of the southern part of the IRL. Water quality and the condition of seagrasses in the area are poor compared with other segments of the lagoon. 

Starting in 2001, responsible agencies including Indian River County, 

SJRWMD, Indian River Farms Water Control District, Vero Beach, and 

the Indian River County IFAS Extension Offi ce organized to develop 

a water management plan. The development of the plan is challenging because the plan will need to balance restoration needs of the IRL 

and drainage needs. Other state and federal agencies will join the effort 

as plans become solidifi ed. The Florida legislature appropriated about 

$5 million to support the effort (Steward et al., 2003; Steward, 2006).

On-site Sewage Treatment and Disposal Systems

On-site sewage treatment and disposal systems (OSTDSs), usually 

septic tanks and drain fi elds, are common in parts of the IRL Basin where 

population densities are low or outside utility service areas. Some of 

the older systems constructed before 1983 may have drain fi elds located 

6 inches or less from the high water table and may have limited capability 

to treat wastewater (SJRWMD, 1996). The IRL SWIM Plan was required 

by the IRL Act, in addition to evaluating the loading from domestic 

wastewater treatment plants, to evaluate OSTDSs and identify problem 

areas that could potentially impact the IRL lagoon system. Actual evaluations were performed by county public health units under contract to the 

SJRWMD in the early 1990s. Problem areas were ranked for the severity 

of threat considering soil permeability, depth to water table, failure, and 

64 Water Quality Assessment Report: Indian River Lagoon
density of septic tanks. Volusia County identifi ed 32 square miles as 

problem areas and another 26.7 square miles as potential problem areas. 

Brevard County identifi ed 22 square miles as problem areas and 9.6 square 

miles as potential problem areas. Indian River County prioritized areas as 

high or medium priority and found that 15.4 square miles were high priority while 16 square miles were medium priority (SJRWMD, 1996).

In response to these fi ndings by county public health units, counties 

took specifi c steps to at least attempt to address the most severe problems. 

In response to fi ndings for Mosquito Lagoon, Volusia County and New 

Smyrna Beach provided sewer service to barrier island communities from 

Ponce de Leon Inlet south to Canaveral National Seashore. There are still 

areas of the mainland that should be considered for central sewer. Brevard 

County’s evaluation of the Banana River watershed identifi ed most septic 

tank systems are on the southern end of Merritt Island. Most problems 

were located in the Newfound Harbor area and many of those homes were 

provided central sewer service. Remaining septic tanks on Merritt Island 

are located on Horti Point and are considered a low pollution threat to 

the Banana River. Problem areas identifi ed by Brevard and Indian River 

Counties were Port St. John, Palm Bay, southern Brevard County, Sebastian, and southeastern Indian River County. Palm Bay and Indian River 

County are continuing to eliminate the use of OSTDSs. Major obstacles 

for the removal of OSTDSs are the cost to the homeowner of connecting to 

central sewer (Steward et al., 2003).

Wetland Restoration 

Wetlands in the IRL Basin have been impacted in many ways. About 

75 percent of the coastal salt marshes in the basin were impounded and 

isolated from open waters for the control of salt marsh mosquitoes by 

mosquito control districts (Indian River Mosquito Control District, 2007). 

Research performed in the 1970s and 1980s showed that there was an 

ecological benefi t to reconnecting salt marshes to the estuary. Research by 

Brockmeyer, Rey, Virnstein, Gilmore, and Earnest (1997) was the basis for 

SJRWMD projects to reestablish wetland connections to the IRL lagoon 

system. Activities to reconnect wetlands were started in 1990. Total 

reconnected acreage from 1990 to 2005 was approximately 29,389 acres 

(Brockmeyer, 2005). The ultimate goal is the reconnection of 33,000 acres 

(Steward et al., 2003). Much of the reconnected acreage was accomplished 

as part of the IRL SWIM Plan (19,703 acres). The remaining 9,686 acres 

of wetlands were reconnected by non-SWIM or private initiatives including 

local governments and the Merritt Island National Wildlife Refuge.

The question of how reconnected impoundments within the Merritt 

Island National Wildlife Refuge will be managed spurred the creation of 

the three-year-long Wetlands Management Research Initiative. Impoundments are closed for long periods of eight months or more as a waterfowl 

and bird management technique. This closure prevents water exchange 

with the estuary, removes access by fi sh, and negatively affects invertebrate and plant communities. An alternate technique known as rotational 

impoundment management opens the impoundments for eight or nine 

months, but requires closure during the summer months for mosquito 

Water Quality Assessment Report: Indian River Lagoon 65
 control. The Wetlands Management Research Initiative is addressing 

the benefi ts and drawbacks to different management techniques with the 

goal of proposing the best management technique or mix of techniques. 

Costs for the initiative are shared by SJRWMD, the Department’s Bureau 

of Survey and Mapping, U.S. Geological Survey, U.S. Fish and Wildlife 

Service, EPA, and other entities involved in research.

Several different techniques are used to vegetate and recreate shoreline 

habitat. Between 1991 and 1995, red and black mangroves (Rhizophora 

mangle and Avicennia germinans) and smooth cordgrass (Spartina alternifl ora) were planted on spoil islands in Indian River and Brevard Counties, 

on the delta at the end of South Relief Canal in Indian River County, 

and near the boat ramp in the Sebastian Inlet Park. Survival at these sites 

was generally less than 5 percent (Steward et al., 2003) with the exception of the South Relief Canal where plantings were protected from wind 

and waves. Later plantings of mangroves were done by planting the tree 

seedlings within the confi nes of a thin-walled PVC pipe. This technique 

is referred to as the Riley Encased Methodology after its inventor. By 

2002, more than 10,000 mangrove seedlings had been planted at 28 sites 

(Steward et al., 2003). Much of the planting is done by volunteers through 

an interagency partnership and the Indian River County Environmental 

Learning Center. Other nonimpacted wetlands are targeted for purchase 

under the Blueways Program. 

Muck Removal

The removal of muck deposits has been identifi ed as one of the strategies that will result in substantial reduction of a source of nutrients and turbidity in the IRL lagoon system. The central lagoon is the primary target 

area, because it contains a large number of muck deposits. The Eau Gallie 

River and Sebastian River are scheduled for dredging of muck by 2010 

(Steward et al., 2003). Earlier muck removal projects in Turkey Creek and 

Crane Creek have been completed. 

The FIND and the USACOE are cosponsors of a 10-year plan for the 

environmental maintenance dredging of the Intracoastal Waterway, which 

contains about 60 to 70 percent of the muck in the IRL Basin. 

Stormwater Improvement Projects

Stormwater runoff is an important source of suspended solids and 

nutrient input to the IRL lagoon system. Since 1995 numerous stormwater 

retrofi t projects have been undertaken to address stormwater issues in the 

basin. The individual planning unit assessments contained in Chapter 3 

and Appendix C describe these projects in detail. General storm water 

management techniques have included installation of baffl e boxes to 

remove sediments and construction of stormwater treatment ponds to 

capture runoff. Phosphorus is typically adsorbed to particles, particularly 

sediment. 

Additional tools for managing stormwater are stormwater management 

plans and stormwater master plans. For example, the city of Edgewater is 

preparing a stormwater master plan that will describe existing conditions 

and recommend improvement projects. Brevard County has completed 

66 Water Quality Assessment Report: Indian River Lagoon
stormwater management plans for the Upper Eau Gallie River and Crane 

Creek. Many other local governments in the basin have also prepared 

stormwater management plans.

Some funding for local stormwater improvement projects has been 

provided from the sale of the IRL specialty license plate, which was established by the Florida legislature under Section 320.08058(10), F.S., and 

fi rst issued in 1995. Revenue from sales of the plate is returned to the 

Volusia, Brevard, Indian River, St. Lucie, and Martin Counties based on 

their proportion of plate sales. Revenue generated from license plate sales 

is distributed as not more than 20 percent for education projects and the 

remaining 80 percent for water quality and habitat restoration projects 

(SJRWMD, 2004). Local governments and nonprofi t organizations are 

eligible to apply for funds, but must be able to provide at least 25 percent 

of the total project cost as matching funds (SJRWMD, 2004). More than 

$3 million has been raised by tag sales with annual average revenue of 

about $400,000.

Many of the local governments in the basin also provide stormwater 

management and retrofi t funds from stormwater utilities. 

Water Quality Assessment Report: Indian River Lagoon 67

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 Indian River Lagoon (IRL) Basin conducted by the 

Florida Department of Environmental Protection (Department). The 

 primary purpose of the assessment was to determine if waterbodies or 

waterbody segments were to be placed on the Verifi ed List of impaired 

waters. The assessment was conducted in accordance with evaluation 

thresholds and data suffi ciency and data quality requirements contained in 

the Identifi cation of Impaired Surface Waters Rule (IWR) (Rule 62-303, 

Florida Administrative Code [F.A.C.]). The results of the assessment were 

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 IRL Basin on which 

the assessment was based. The Assessment by Planning Unit section of 

this chapter provides descriptions of each planning unit as well as summaries of the key water quality indicators in each unit, 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 assessment 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 

in this chapter, 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 

provides supplemental ecological information for the IRL Basin. 

Appendix C provides an overview of water quality improvement and habitat restoration projects in the IRL Basin. Appendix D provides additional 

information on reasonable assurance. Appendix E provides the methodology used to develop the Planning and Verifi ed Lists. The complete text 

of the IWR is available at http://www.dep.state.fl .us/legal/Rules/shared/ 

62-303/62-303.pdf. Appendix F contains the water quality assessment 

Master List summary (Table F.1) and the water quality monitoring stations used in the assessment (Table F.2). Appendix G lists, by planning 

Water Quality Assessment Report: Indian River Lagoon 69
unit, permitted wastewater treatment facilities in the basin that discharge 

to surface water and ground water, as well as hazardous waste sites, landfi lls, and brownfi elds. Appendix H lists Level I land use by planning unit. 

Appendix I lists statistical summary sheets for ground water evaluations in 

the IRL.

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 Central 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 St. Johns River Water 

Management District (SJRWMD) and local and county governments to 

obtain applicable monitoring data from their routine monitoring programs 

and special water quality projects in the basin.

Nine waterbody segments on the Planning List and the 1998 303(d) 

list needed further data to verify impairment. Parameters included 

copper, DO, nutrients (chlorophyll a and historical chlorophyll), silver, 

and thallium.

Sixty-eight waterbody segments were verifi ed impaired for at least 

one parameter in the IRL Basin as the result of strategic monitoring and 

data-gathering activities in Phase 2. Table F.1 in Appendix F provides the 

updated impairment status of the basin through June 30, 2006.

Sources of Data

The assessment of water quality in the IRL 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 modern STORET databases, the U.S. 

Geological Survey, 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, local governments, 

and volunteer monitoring groups. Appendix E 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 IRL Basin for the planning and verifi ed periods 

of record used in this assessment. Major data providers were SJRWMD, 

Florida Department of Agricultural and Consumer Services (DACS) and 

the Marine Resources Council. Figure 3.1 shows the amount of data provided by each source in each year of the planning and verifi ed periods.

Water Quality Assessment Report: Indian River Lagoon 71
In 2002, the Department created the IWR Database to evaluate data 

in accordance with the methodology prescribed in the IWR. For the 

Planning List assessment, the data evaluation period of record is 10 years, 

and for the Verifi ed List it is 7.5 years. Table E.2 in Appendix E 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 IRL 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.

72 Water Quality Assessment Report: Indian River Lagoon
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 (Wayland, 2001). 

Following the EPA’s guidance, the Department delineated water bodies 

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 

report integrates the 303(d) list and the 305(b) report for the IRL Basin; it 

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 waterbodies 

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 93 waterbodies or waterbody segments 

in the IRL 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. No waterbody segments in the 

IRL Basin fall into Category 2.

Most waterbodies in the state, however, fall into Category 3 (having 

insuffi cient data). In the IRL Basin, the breakdown of waterbodies or 

 segments in Category 3 is as follows:

• Category 3a—No segments for which absolutely no data were available to determine their water quality status;

• Category 3b—16 segments with some data, but insuffi cient data for 

making any determinations; and

• Category 3c—9 potentially impaired segments based on 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.

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: Indian River Lagoon 73
Table 3.3: Categories for Waterbodies or Waterbody Segments in the 2002 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.

74 Water Quality Assessment Report: Indian River Lagoon
Currently, no 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—No segments 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—No 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, 68 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 IRL Basin encompasses approximately 1,410 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 

waters submitted to the EPA in reports under Section 303(d) of the Clean 

Water Act.

Although WBIDs often encompass several waterbodies, water quality 

data usually refl ect conditions within the main waterbody within a 

 polygon. In some instances, however, the data from several waterbodies 

within the polygon have been aggregated. As the water quality assessments 

are refi ned in Phase 2 of the watershed management cycle, individual waterbodies within these aggregations that have unique water quality concerns 

will be assigned unique WBIDs and evaluated individually.

Water Quality Assessment Report: Indian River Lagoon 75
The IRL Basin contains fi ve planning units: Mosquito Lagoon, 

Banana River, North IRL, North Central IRL, and South Central IRL. 

Figure 3.2 shows the locations and boundaries of each planning unit. 

Descriptions of each planning unit are provided in the Assessment 

by Planning Unit section of this chapter, along with information on land 

uses 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 F contains the water quality assessment Master List summary (Table F.1) and the water quality monitoring stations used in the 

assessment (Table F.2) by planning unit. Appendix G lists, by planning 

unit, permitted wastewater treatment facilities in the basin that discharge 

to surface water and ground water, as well as hazardous waste sites, landfi lls, and brownfi elds. Appendix H lists Level I land use by planning unit.

Seagrass Assessment

Seagrass assessment in the IRL lagoon system was conducted by comparing the existing seagrass depth limit to the target depth limit, which was 

defi ned in the Pollutant Load Reduction Goal (PLRG) developed by the 

SJRWMD (Steward and Green, 2006). Impairment was identifi ed if the 

existing seagrass depth limit was shallower than the target depth limit.

To conduct the seagrass assessment, SJRWMD divided the IRL lagoon 

system into several geographically, morphometrically, and hydrodynamically distinct regions (sublagoons) including the Banana River Lagoon 

(BRL), North Indian River Lagoon (North IRL), and Central Indian River 

Lagoon (Central IRL). (Please note that these sublagoon delineations are 

not related to the planning unit delineation used in the Department’s water 

quality assessment.) Mosquito Lagoon was not included in the PLRG 

analyses because seagrass coverage of the lagoon did not change suffi ciently 

for the identifi cation of a causative pollutant. 

The North IRL, Central IRL, and BRL sublagoons were further 

divided into segments (Figure 3.3). Several factors were considered in 

setting segment boundaries (Steward and Green, 2006). The primary 

factor was the presence of causeway bridges (13) that cross the IRL lagoon 

system, where disruptions in hydrodynamic circulation patterns have either 

been observed or presumed to exist (Evink, 1980), and where changes in 

seagrass coverage patterns were apparent (Virnstein, Steward, Morris, and 

Beck, 2003). Large island groupings, cuspate spits, and major tributaries 

were also considered in setting boundaries. Final segmentation was based 

on spatial analyses of water quality data through principal component 

analysis (PCA), and cluster and kriging analyses. PCA identifi ed turbidity 

and salinity as the principal variables responsible for inter-segment variability. Contiguous segments were aggregated if no signifi cant turbidity 

and salinity differences were found between them (via kriging and cluster 

analysis by Sigua, Steward, and Tweedale, 1996). The fi nal outcome was 

an IRL-BRL system divided into 15 segments as shown in Figure 3.3 

(Steward, 2006).

Seagrass depth limits were determined from depth measurements 

obtained from a 1996 bathymetric data set developed by Coastal Planning 

& Engineering (1997). Depth measurements closest to a segment’s seagrass 

deep-edge boundary in a given year were selected as the depth limit for the 

year using a set of rules that served to capture only the appropriate bathymetric data and exclude other data that could create erroneous depth limits 

(e.g., near or within dredged areas and the shallow edges of seagrass beds) 

(Steward, Virnstein, and Morris, 2005). 

A seagrass full restoration target is based on the union of all the 

mapped seagrass coverages available from 1943 to 1999, which encompassed every area where seagrass had been mapped (Steward et al., 

2005). The fi nal seagrass full restoration target was established as a 10 

percent departure from the deep-edge boundary delineating this union 

coverage. The basis for the 10 percent departure was Florida’s water 

transparency standard (Rule 62-302.530, F.A.C.), which stipulates that 

the “depth of the compensation point for photosynthetic activity [as it 

relates to seagrass depth limits in this case] shall not be reduced by more 

than 10 percent as compared to the natural background value.” Natural 

background is defi ned as “the condition of waters in the absence of maninduced alterations based on the best scientifi c information available” (Rule 

62-302.200[15], F.A.C.). Natural background values for water transparency are relevant in this case. 

Using the assessment method described above, none of the PLRG 

segments in the IRL-BRL subbasins, and therefore none of the Department’s WBIDs in these areas, met the seagrass full restoration target 

(Figure 3.3a). Based on previous studies, the major pollutants responsible 

for this depression were total suspended solids (TSS) and the nutrients total 

nitrogen and total phosphorus (Steward, Brockmeyer, Gostel, Sime, and 

Van Arman, 2003; Hanisak, 2001). All of the WBIDs in the IRL lagoon 

system were deemed impaired for nutrients. 

Fish Consumption Advisories

The DOH has issued several fi sh consumption advisories that affect the 

IRL Basin. The advisory for pufferfi sh recommends that pufferfi sh caught 

in the IRL or coastal waters of Brevard, Indian River, Martin, St. Lucie, 

and Volusia Counties not be consumed (DOH, 2005). The advisory was 

issued because of the presence of saxitoxin in pufferfi sh tissue, including northern, southern, marbled, bandtail, checkered, and least pufferfi sh 

 species (DOH, 2005). In 2002, numerous people became ill after consuming pufferfi sh caught in the lagoon, and the source of the saxitoxin was 

suspected to be a native alga, but this has not been confi rmed (SJRWMD, 

2005b). Saxitoxin poisoning can lead to neurological symptoms such as 

tingling, burning, numbness, incoherent speech, diffi culty in breathing, 

and in rare extreme cases, death. The Florida Fish and Wildlife Conservation Commission prohibits the harvest of pufferfi sh. 

Consumption guidelines were issued for a substantial number of other 

marine and estuarine fi sh in coastal waters of Florida, including those in

Certain species such as blackfi n tuna, crevalle jack, cobia, great barracuda, 

king mackerel, little tunny, and all species of shark should not be consumed by women of childbearing age or by children. For other adults, king 

mackerel greater than 31 inches fork length and shark 43 inches or longer 

are not recommended for consumption. Guidelines recommend limited 

consumption of many other fi sh species. The DOH document Your Guide

describes how fi sh consumption advisories are addressed by the IWR assessment for impairment. For this report, consumption advisories for mercury 

in fi sh were included as a source of impairment, but advisories for saxitoxin 

were not included pending further review by the Department to determine 

if there is a causative link to a specifi c pollutant.

Assessment by Planning Unit

• Banana River Planning Unit

General Description

The Banana River Planning Unit covers about 327.7 square miles in 

Brevard County and extends from just south of the A. Max Brewer Memorial Parkway near Titusville, south to the Eau Gallie Boulevard Causeway 

near Eau Gallie. It contains 14 waterbody segments (WBIDs). Major 

waterbodies in the planning unit include the Banana River and the coastal 

Atlantic beaches and nearshore coastal waters. Sykes Creek is a tributary to 

the planning unit. Major cities in the planning unit include Cocoa Beach, 

Satellite Beach, and Cape Canaveral. Patrick Air Force Base is located near 

the southern end of the planning unit, while Cape Canaveral Air Force 

 Station is located near the northern end.

Water Quality Summary

Of the 14 waterbody segments in the Banana River Planning Unit, 

14 segments have suffi cient data for assessment. Of these, 14 are verifi ed 

impaired for at least one parameter assessed, none remain on the Planning 

List, and none meet standards.

Data from 110 water quality monitoring stations were used for evaluation of impairment. Figure 3.4, a composite map of the planning unit, 

shows waters on the 1998 303(d) list, the Planning List and Verifi ed List, 

and potential pollution sources. Table 3.4 summarizes the water quality 

assessment status of all waterbody segments in the planning unit.

All of the waterbody segments in the planning unit are impaired for 

mercury in fi sh. Several studies and reports have noted that historically the 

southern part of the Banana River, near Patrick Air Force Base, has consistently had high sediment and water column concentrations of trace metals 

(Trefry, Metz, Trocine, Iricanin, Burnside, Chen, Webb, 1990; Trocine and 

Trefry, 1993; Hand and Paulic, 1992, as referenced in Woodward-Clyde 

Consultants, 1994b).

Table 3.4 (continued)

Noncoastal Banana River waterbody segments are also impaired 

for DO and nutrients. The assessment of nutrient impairment in these 

segments was based on seagrass information (other information). Average annual loadings of nutrients and TSS (based on 1995 estimates) from 

nonpoint sources have more than doubled since 1942 (Steward et al., 

2003). A large portion of the loading increase is attributed to the central 

and southern parts of the Banana River (Seagrass Assessment Segments BR 

3–7). Water quality improvement projects and activities that will result in 

decreased loadings are summarized in the Water Quality Improvement 

Plans and Projects section.

Permitted Discharges and Land Uses

Point Sources: There are 25 permitted wastewater discharges in the 

planning unit, 1 hazardous waste site, and 4 landfi lls. Of the wastewater 

discharges, 8 are domestic wastewater and 17 are industrial wastewater. 

84 Water Quality Assessment Report: Indian River Lagoon
The largest National Pollutant Discharge Elimination System 

(NPDES) wastewater discharger is Cocoa Beach (6 million gallons per day 

[mgd]) followed in size by Cape Canaveral (1.8 mgd). Several industrial 

facilities (7) are also permitted for stormwater discharges. 

A Cocoa Beach Gasoline Contamination site was delisted in September 

1988 (Department, 2005a) after removal of contaminants under the State 

Waste Cleanup Program. The site was determined to be contaminated in 

1984 with gasoline and petroleum products (benzene, xylene, and toluene) 

from leaking gasoline tanks at a nearby car wash.

There is one active sludge disposal landfi ll at Cape Canaveral Air Force 

Station. Other landfi lls in the planning unit receive seafood processing 

waste and land clearing debris, and one is a garbage transfer station.

Figure 3.4 shows the locations of these discharges in the planning 

unit (see Noteworthy for a defi nition of point sources and a discussion of 

environmental remediation). Appendix G lists the basin’s domestic and 

industrial permitted discharge facilities, along with their permitted fl ows, 

by planning unit. It also lists landfi lls or solid waste facilities and Superfund sites by planning unit (see Noteworthy: Environmental Remediation

for more information on the Superfund Program).

Nonpoint Sources: Based on land use data collected and delineated 

from year 2000 aerial photography, almost 70 percent of the planning unit 

is covered by water and wetlands. Another 14 percent of the planning 

unit is range and upland forest, composed primarily of shrub, brushland, 

and xeric oak forest. About 12 percent of the planning unit is composed 

of residential, commercial, and light industrial land uses. Most residential 

development is at medium density (2 to 5 dwellings/acre) and high density 

(6 or more dwellings/acre). Canaveral Air Force Base and the Kennedy 

Space Center cover about 4 percent of the planning unit. Table H.1 in

Appendix H provides summary information on Level I land uses in the 

planning unit.

Different land uses are associated with nonpoint source pollutant 

 discharges and eroded sediments (see Noteworthy for a defi nition of nonpoint sources). In urban areas, stormwater discharges are managed through 

municipal separate storm sewer system (MS4) permits. Cocoa Beach, 

Satellite Beach, Patrick Air Force Base, and Cape Canaveral have Phase 2 

MS4 permits.

Ecological Summary

Evaluation of the condition of seagrass communities revealed that 

seagrass coverage was stable in the planning unit throughout the 1990s. A 

shift in the composition of the seagrass community occurred in the Banana 

River in the later 1990s during a period of low salinity concurrent with a 

period of high rainfall. Syringodium fi liforme decreased in abundance while 

Ruppia maritime increased during that time period. 

Drift macroalgae are found in the central segments in greater abundance than other segments of the Banana River. Macroalgae utilize 

nutrients that would otherwise be available to phytoplankton, thus limiting 

phytoplankton growth (Davis, Zimmermann, and Montgomery, 1983).

The current condition of seagrass beds in this planning unit is 

 further assessed and summarized in the Seagrass Assessment section of 

this chapter based on information provided by SJRWMD (Steward and 

Green, 2006). 

Water Quality Improvement Plans and Projects

Numerous water quality improvement and habitat restoration projects 

have been undertaken or are currently planned in this planning unit 

(Appendix C). Financial support for projects described in this section 

has come from the Department, SJRWMD, Brevard County Storm water 

 Utility Department, local governments, and the Indian River Lagoon 

National Estuary Program (IRLNEP). Information summarized in this 

section was obtained from the IRL Surface Water Improvement and Management (SWIM) Plan (Steward et al., 2003), Brevard County Stormwater 

Utility Program (Powers, 2006), and by personal communication with 

Bob Day with the IRLNEP (2005). Stormwater retrofi t projects discussed 

cover the period from 1995 to 2005. Brevard County and many of its 

municipalities have completed or have under way numerous projects that 

better manage stormwater runoff. Cape Canaveral, Cocoa Beach, and 

Satellite Beach are preparing surface water management plans as a means 

to more fully address stormwater issues in their respective communities. 

The following describes many of the local projects implemented or under 

construction in the planning unit.

• Satellite Beach: Satellite Beach has completed the installation of 

permeable pavement and an exfi ltration trench on Wilson Avenue. 

Exfi ltration trenches installed on Jackson Avenue will treat stormwater from 20 acres and also decrease the frequency of fl ooding in 

the area. Three wet detention ponds in the Jamaica Boulevard area 

have been constructed to treat runoff from 201 acres of the DeSoto 

Parkway watershed. Installation of baffl e boxes is also planned 

for this watershed. Baffl e boxes have been installed for a 20-acre 

 residential development on Roosevelt Avenue and are planned for 

Grant Avenue to treat a 96-acre watershed. 

• Merritt Island and other unincorporated areas: Brevard County 

has connected about 75 residences and businesses located in Merritt 

Park Place to central sewer. Brevard County is responsible for 

stormwater management on Merritt Island. The county has plans 

to divert a ditch on the Merritt Island Airport from the Banana 

River into a regional detention pond. The county has installed curb 

and grate inlet baskets in storm drains on Merritt Island, some with 

oil absorption pillows, to reduce the amount of trash reaching the 

Banana River and the northern part of the IRL, while in residential 

areas baffl e boxes have been installed to reduce sediments entering the IRL. The county has secured funds to install an additional 

8 to 10 baffl e boxes over the next 4 years to reduce sediment loads 

from Merritt Island to the IRL. The county also constructed the 

 Merritt Ridge Alum Treatment Plant to treat stormwater runoff from 

314 acres of residential, commercial, and industrial development. 

Water Quality Assessment Report: Indian River Lagoon 87
Funds from a federal 319(h) grant provided partial fi nancial support 

for the construction of a detention pond located at Florida Boulevard. County stormwater utility funds were used to construct a 

second pond on South Tropical Trail Lane. The Florida Boulevard 

pond will treat 178 acres of residential and commercial development 

and the Tropical Trail Lane pond will treat 35 acres of residential 

development.

• South Patrick area: Brevard County, using stormwater utility 

funds, has completed construction of a two-acre regional detention 

pond at the abandoned Sea Park Sewer Plant in the South Patrick 

area. Accompanying the detention pond are soccer fi elds, a park, 

and playground. Water detained in the pond is used to irrigate the 

soccer fi elds. 

• North Merritt Island: Brevard County has initiated the Lake 

George Water Quality Improvement Project. This project will 

reroute an existing agricultural discharge and direct it to two stormwater ponds and wetland treatment areas prior to discharge into the 

IRL/Banana River through the barge canal. 

• Cape Canaveral: Cape Canaveral has installed a Continuous 

Defl ective Separation unit to trap sediment in runoff from the property of the city’s wastewater treatment plant facility. A second baffl e 

box was installed at International Drive that treats a 195-acre urban 

watershed. 

• Cocoa Beach: Cocoa Beach has installed inlet baskets in storm 

drains to prevent debris from entering the storm sewer. The city has 

also constructed a bioretention facility on Brevard Avenue to serve 

an old downtown area. A baffl e box has been installed at Second 

Street South to capture sediments from an approximate 10-acre 

basin. There are plans for a detention pond at Maritime Hammock 

Preserve that will use alum treatment as part of a pollutant removal 

system. This system will serve an 80-acre watershed.

Restoring habitat to the Banana River is an important component in 

the overall rehabilitation of the IRL lagoon system. About 1,967 acres of 

wetlands, mostly in the Sykes Creek/Newfound Harbor area, are included 

in the Blueway land acquisition project. Two separate mangrove plantings 

were accomplished at Kelly Park on Merritt Island during 1997 and 1998. 

There are 5,079 acres of impounded wetlands in the planning unit; 

about half that total (2,490 acres) has been breached or reconnected to 

the Banana River (Brockmeyer, 2005). Most of the reconnected acreage 

is located in the Sykes Creek watershed and was reconnected as part of a 

mitigation project (Steward et al., 2003). About 2,589 remaining acres of 

impounded wetlands are targeted for reconnection in the future (Steward 

et al., 2003; Brockmeyer, 2005).

There are also about 430 acres of dragline-impacted wetlands in the 

planning unit. A workplan for restoration of this acreage is in development 

(Steward et al., 2003).

88 Water Quality Assessment Report: Indian River Lagoon
Waters will not be placed on the Verifi ed List if the Department 

receives reasonable assurance that existing or proposed projects and/or programs are expected to result in the attainment of water quality standards or 

consistently improve water quality over time. Appendix D contains more 

detailed documentation of the requirements for reasonable assurance. For 

this planning unit, no management plans or projects complying with the 

Department’s guidance for reasonable assurance have been provided for the 

Verifi ed List of impaired waters.

• Mosquito Lagoon Planning Unit

General Description

The Mosquito Lagoon Planning Unit covers about 266.8 square miles 

in Volusia and Brevard Counties and extends from just north of Ponce de 

Leon Inlet near New Smyrna Beach, south just past the A. Max Brewer 

Memorial Parkway near Titusville. It contains 14 waterbody segments 

(WBIDs). Major waterbodies in the planning unit are Mosquito Lagoon 

and the coastal Atlantic beaches and nearshore coastal waters. Cities 

located in the planning unit include Oak Hill, Edgewater, and New 

Smyrna Beach.

Water Quality Summary

Of the 14 waterbody segments in the Mosquito Lagoon Planning Unit, 

13 segments have suffi cient data for assessment. Of these, 13 are verifi ed 

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

List, and none meet standards.

Data from 65 water quality sampling stations were used for assessment 

of impairment. Figure 3.5, a composite map of the planning unit, shows 

waters on the 1998 303(d) list, the Planning List and Verifi ed List, and 

potential pollution sources. Table 3.5 summarizes the water quality assessment status of all waterbody segments in the planning unit.

The southern part of Mosquito Lagoon (WBID 2924) is impaired for 

DO and mercury in fi sh. All other waterbody segments in the planning 

unit are impaired for mercury in fi sh only. 

Average annual nonpoint source loadings of TSS and nutrients (based 

on 1995 estimates) have increased by a factor of 1.5 in Mosquito Lagoon 

when compared with 1943 loadings (Steward et al., 2003). Water quality 

improvement projects and activities that will result in decreased loadings 

are summarized in the Water Quality Improvement Plans and Projects

section.

Permitted Discharges and Land Uses

Point Sources: There are six permitted point source discharges in the 

planning unit, with three being landfi lls. Of the three landfi lls, two are 

active solid waste transfer stations located in Edgewater and New Smyrna 

Beach. The Oak Hill Landfi ll is closed. There are no hazardous waste sites 

or ground water contamination areas in the planning unit. 

The largest point source discharge in the planning unit is 7 mgd from 

the New Smyrna Beach Reclamation Facility and the 2.25 mgd NPDES 

discharge from the Edgewater wastewater treatment plant. The remaining

 discharge facilities, along with their permitted fl ows, by planning unit. It 

also lists landfi lls or solid waste facilities and Superfund sites (EPA, 2007a) 

by planning unit.

Nonpoint Sources: Based on land use data collected and delineated 

from year 2000 aerial photography, about 82 percent of the planning unit 

is water and wetlands. Residential, commercial, and light industrial uses 

cover another 6.5 percent of the planning unit. Most residential development is medium and high density. Conservation and recreation lands in 

the planning unit include Canaveral National Seashore and Park, New 

Smyrna Dunes State Park, Riverbreeze Park, Bethune Beach Ocean, and 

River Park. Table H.2 in Appendix H provides detailed information on 

land uses in the planning unit.

Different land uses are associated with nonpoint source pollutant 

 discharges and eroded sediments. In urban areas, stormwater discharges 

are managed through MS4 permits.

Ecological Summary

The southern part of Mosquito Lagoon contains one of the more 

extensive seagrass coverages in the IRL lagoon system, with little change 

observed since 1943. The area of Mosquito Lagoon with the least coverage 

and greatest loss of seagrass since 1943 is the northernmost area near New 

Smyrna Beach. This area has experienced as much as a 94 percent loss of 

seagrasses. The current condition of seagrass beds in this planning unit is 

further assessed and summarized in the Seagrass Assessment section of 

92 Water Quality Assessment Report: Indian River Lagoon
this chapter based on information provided by SJRWMD (Steward and 

Green, 2006). 

Unlike more southern parts of the IRL lagoon system, generally little 

muck is found deposited in Mosquito Lagoon (Steward et al., 2003). The 

muck is easily resuspended, resulting in increased turbidity, reduced light 

penetration, increased oxygen demand, and release of nutrients to the 

water column. 

Water Quality Improvement Plans and Projects

Habitat restoration and numerous water quality improvement 

 projects have been undertaken or are currently planned in this planning 

unit (Appendix C). Financial support for projects has come from the 

SJRWMD, local governments, and the IRLNEP. Information summarized 

about example projects in this section was obtained from the IRL SWIM 

Plan (Steward et al., 2003) and by personal communication with Bob Day 

with the IRLNEP (2005). Stormwater retrofi t projects discussed cover the 

time period from 1995 to 2005.

New Smyrna Beach has made substantial progress with the management of both wastewater discharges and stormwater runoff. The city has 

completed construction of a wastewater treatment plant located west of 

Interstate 95. The plant includes up to a 6 mgd capacity reuse system, 

which will account for most of the plant’s discharge. Wet weather discharge from the plant is still permitted. Several stormwater management 

plans and projects have been completed or are in development within 

New Smyrna Beach. The city installed baffl e boxes at the intersection of 

 Riverside and Wayne Avenues in 1997 and 1998 to prevent sediments from 

entering Mosquito Lagoon. Several sediment traps have been installed in 

the drainage system along Riverside and Magnolia Avenues. The city is 

also doing a stormwater retrofi t at the New Smyrna Beach Marina. This 

retrofi t requires use of a baffl e box to capture runoff from three existing 

outfalls. New Smyrna Beach also has projects pending to install baffl e 

boxes at Quay Assisi and upgrading drainage at East Circle.

The city of Edgewater is preparing a Stormwater Master Plan. The 

city has plans to construct a 2.25 million gallon storage tank that will hold 

reclaimed water during wet weather. The water can be used for irrigation 

in dry weather. Edgewater has undertaken the installation of baffl e boxes 

at Mango Tree Drive and Gabordy Canal to reduce the amount of sediment entering Mosquito Lagoon. 

The city of Oak Hill has completed a stormwater master plan for the 

city. This plan includes several projects that when constructed will reduce 

pollutant loadings to Mosquito Lagoon. 

Restoring wetland habitat in Mosquito Lagoon is an important component in the overall rehabilitation of the IRL lagoon system. The Volusia Soil and Water Conservation District has received funding to plant 

red mangroves and cordgrass at fi ve locations in the Canaveral National 

 Seashore property. 

About 5,100 acres of mosquito impoundments have been reconnected 

or restored in this planning unit (Brockmeyer, 2005). The University of 

Central Florida and The Nature Conservancy have recently initiated a 

Water Quality Assessment Report: Indian River Lagoon 93
 project to restore several acres of oyster bars in Mosquito Lagoon using 

mats with attached oyster shells.

Waters will not be placed on the Verifi ed List if the Department 

receives reasonable assurance that existing or proposed projects and/

or programs are expected to result in the attainment of water quality 

standards or consistently improve water quality over time. Appendix D 

contains more detailed documentation of the requirements for reasonable 

assurance. For this planning unit, no management plans or projects complying with the Department’s guidance for reasonable assurance have been 

provided for the list of impaired waters.

• North Indian River Lagoon Planning Unit

General Description

The North IRL Planning Unit covers about 281.2 square miles in 

Volusia and Brevard Counties and extends from just south of New Smyrna 

Beach near the community of Edgewater, south to Horse Creek located 

north of Eau Gallie. It contains 9 waterbody segments (WBIDs). Major 

waterbodies in the planning unit are the Indian River Lagoon and Banana 

Creek. Tributaries to the planning unit are Turnbull Creek, Addison 

Creek, and Horse Creek. Haulover Canal connects Mosquito Lagoon to 

the northern part of the IRL. Major cities in the planning unit are Cocoa, 

Rockledge, and Titusville.

Water Quality Summary

Of the nine waterbody segments in the North IRL Planning Unit, 

nine segments have suffi cient data for assessment. Of these, six are verifi ed 

impaired for at least one parameter assessed, three remain on the Planning 

List, and none meet standards.

Data from 243 water quality monitoring stations were used for assessment of impairment. Figure 3.6, a composite map of the planning unit, 

shows waters on the 1998 303(d) list, the Planning List and Verifi ed List, 

and potential pollution sources. Table 3.6 summarizes the water quality 

assessment status of all waterbody segments in the planning unit.

Five of the nine waterbody segments of this planning unit are impaired 

for mercury in fi sh. Fish consumption advisories have been issued for the 

IRL from the Melbourne Causeway north to the A. Max Brewer Memorial 

Parkway. Other metals impairments in the unit include copper and nickel. 

Studies and reports have noted that historically the portion of the planning 

unit between Titusville and Cocoa has consistently had high sediment, 

water column, and marine organism tissue concentrations of trace metals 

(Trefry et al., 1990; Trocine and Trefry, 1993; Hand and Paulic, 1992, as 

referenced in Woodward-Clyde Consultants, 1994b). Trocine and Trefry 

(as referenced in Woodward-Clyde Consultants, 1994b) noted elevated 

levels of copper and trace metals in clam tissue collected adjacent to parts 

of the IRL. This area includes hard clam harvesting beds. Trocine and 

Trefry (1993) speculated that the source of dissolved copper in the water 

column was leachate from antifouling paints used on ships.

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. 4Parameters in bold meet the Verified List evaluation criteria, Section 62-303.400, F.A.C. 5Parameters in italics are in Category 4 (a, b, or c) waters that do not require TMDL development. 6The assessment categories listed in this column represent the status of each WBID as a whole, based on multiple parameters. 

The hierarchy for 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 total coliforms as 

Category 5, fecal coliforms as Category 3c, and coliforms–shellfish as Category 2, the single assessment call for the WBID is 

Category 5.

Water Quality Assessment Report: Indian River Lagoon 97
The Indian River waterbody segments of the planning unit are 

impaired for nutrients, largely based on assessment of other information. 

Some segments are also impaired for DO. 

Average annual loadings of nutrients and TSS (based on 1995 estimates) have increased in the northern part of the IRL since 1943, though 

the increases are substantially lower than the central part of the IRL 

(Steward et al., 2003). Water quality improvement projects and activities 

that will result in decreased loadings are summarized in the Water Quality 

Improvement Plans and Projects section.

Permitted Discharges and Land Uses

Point Sources: There are 29 permitted wastewater discharges, 

2 hazardous waste sites, and 6 landfi lls in this planning unit. 

Of the 29 permitted wastewater discharges, 12 are industrial wastewater, 15 are domestic wastewater, 1 is from a concrete batch plant, and 

1 is a petroleum cleanup site. The largest industrial discharges are cooling water from the Reliant Energy (820 mgd) and Florida Power and 

Light (800 mgd) plants. The largest domestic wastewater discharges are 

from the Cocoa Water Reclamation Facility and Titusville North Water 

 Reclamation Facility. 

The Weekley Lumber hazardous waste site is located in Rockledge. 

It is an active site that is being remediated under the State Waste Cleanup 

Program (Department, 2005b). Contaminants at this site are associated 

with wood preservation. Soils are contaminated with copper, chromium, 

and arsenic with some onsite leaching into the surfi cial aquifer. 

The Skipper’s III, Inc., hazardous waste site is located in Cocoa. It is 

also an active site that is being remediated under the State Waste Cleanup 

Program (Department, 2005c). Contaminants at this site are associated 

with electroplating. Elevated levels of arsenic and chromium were detected 

in onsite soils, and levels exceeding primary drinking water standards 

for cadmium, chromium, lead, nickel, and thallium have been found in 

ground water. Soils have been removed from the site and a ground water 

monitoring plan has been implemented. 

Of the six listed landfi lls, three are closed or inactive dump sites, one is 

for debris, one is for waste tire processing, and one is for special waste. 

Figure 3.6 shows the location of these discharges in the planning unit. 

Appendix G lists the basin’s domestic and industrial surface discharge 

facilities, along with their permitted fl ows, within the planning unit. It 

also lists Superfund sites and landfi lls or solid waste facilities.

Nonpoint Sources: Based on land use data delineated from 2000 

aerial photography, more than 68 percent of the planning unit is water and 

wetlands. Urban and built-up land covers 11.3 percent of the planning 

unit’s area. Residential land use is a fairly equitable mix of low, medium, 

and high density residential. Commercial, institutional, and other industrial land uses occupy more than 1.7 percent of the planning unit. The 

Kennedy Space Center is located on north Merritt Island. Table H.3 in 

Appendix H provides summary and detailed information on land uses in 

the planning unit.

98 Water Quality Assessment Report: Indian River Lagoon
Different land uses are associated with nonpoint source pollutant 

 discharges and eroded sediments. In urban areas, stormwater discharges 

are managed through MS4 permits. Cocoa, Rockledge, and Titusville all 

have MS4 Phase 2 permits.

Ecological Summary

Based on SJRWMD’s seagrass assessment index, seagrass coverage 

north of NASA Causeway is rated good to excellent (segments IR1–5). 

Overall ratings for these fi ve segments are good with no defi ciencies for any 

of the indicators based on 1991–1996 data. The current seagrass coverage is 

slightly larger in area when compared with seagrass coverage in 1943. The 

segment of the IRL immediately south of Titusville (IR5) is consistently 

ranked as one of the best with regard to total acreage and depth of seagrass 

coverage. Though this part of the IRL is poorly fl ushed, it is comparatively less intensively developed than the more southern parts of the lagoon, 

which may be a positive benefi t for seagrasses. The areas with the poorest 

ratings for seagrasses are segments IR6–8, based on data from 1991 to 

1996. These segments are located in the more developed parts of the planning unit and are potentially subjected to greater variability in hydrology. 

More recent analysis of seagrass data collected from 1998 to 2003 

 indicated that segments IR6–8 have improved enough to be classifi ed as 

good, but segment IR3 has declined to a fair ranking (Steward, 2006). 

Although seagrass coverage in some segments was improved in the last 

decade, seagrass depth-limit in none of these segments has reached the full 

restoration target. Therefore, all of the mainstem waterbody segments in 

the North IRL Planning Unit were assessed as being impaired for nutrients 

based on seagrass information.

The current condition of seagrass beds in this planning unit is further 

assessed and summarized in the Seagrass Assessment section of this 

chapter based on information provided by the SJRWMD (Steward and 

Green, 2006). 

Water Quality Improvement Plans and Projects

Numerous water quality and habitat improvement projects have been 

undertaken or are currently planned in this planning unit (Appendix C). 

Financial support for projects has come from the SJRWMD, local governments, Brevard County Stormwater Utility, federal 319(h) grants, and the 

IRLNEP. Project information summarized in this section was obtained 

from the IRL SWIM Plan (Steward et al., 2003), Brevard County Stormwater Utility Department (Powers, 2006), and by personal communication with Bob Day with the IRLNEP (2005). Stormwater retrofi t projects 

discussed cover the time period from 1995 to 2005.

Brevard County has initiated or completed a number of stormwater 

improvement projects in the Titusville, Merritt Island, Port St. John, and 

Scottsmoor areas. 

• Titusville: Brevard County has constructed a stormwater weir at 

the Kennedy Point Marina south of Titusville. The weir will collect 

sediments from a 320-acre drainage basin. 

Water Quality Assessment Report: Indian River Lagoon 99
• Titusville area: Brevard County’s recently completed Chain of 

Lakes Regional Stormwater Treatment Facility provides stormwater 

treatment for the fi rst fl ush of runoff from an 850-acre watershed. 

This project consists of a 40-acre lake constructed for stormwater 

treatment and the reestablishment of 14 acres of wetlands that will 

treat stormwater from Titusville and unincorporated areas of Brevard 

County and relieve fl ooding from the Coleman Ditch. The project 

contains recreational and public education elements. Project partners 

are the SJRWMD, Brevard Community College, Parrish Medical 

Center, Brevard County Parks and Recreation, and Brevard County 

Stormwater Utility Department (Brevard County Stormwater Utility 

Department, 2006).

• Merritt Island and other unincorporated locations: On north 

 Merritt Island, the county is converting 2 large borrow pits located 

on Pine Island to function as stormwater treatment ponds. These 

ponds will serve a drainage basin of approximately 750 acres. 

• Port St. John: Brevard County installed baffl e boxes at Sunrise 

 Village and constructed detention ponds off Broadway Boulevard 

and at Port St. John Basin C/Albin Street and Port St. John Basin B/

Parrish Medical Center. The Broadway Boulevard Pond will treat 

127 acres of residential area.

• Scottsmoor: Brevard County prepared a Master Stormwater Plan 

for Scottsmoor in the early 1990s. The plan recommended the 

construction of stormwater ponds in the Scottsmoor area including 

the Huntington Road Pond, Flounder Creek Pond, and John’s Road 

Pond. These ponds were constructed to treat stormwater runoff 

from agricultural and residential land uses and relieve fl ooding. 

The larger cities located in this planning unit have initiated additional 

independent or cooperative projects directed at the management of stormwater runoff. Rockledge has completed installation of baffl e boxes in the 

Rockledge Drive, Barton Avenue, and Orange Avenue areas and plans to 

install another baffl e box at the corner of Rockledge Avenue and Rockledge 

Drive to trap sediments from more than an eight-acre drainage basin. The 

city has plans to install baffl e boxes at each stormwater outfall entering the 

IRL by 2010 (Day, 2005). The SJRWMD and Rockledge are partnering 

for the construction of a stormwater detention pond that will address fl ooding in the Fiske Boulevard area.

The city of Titusville’s Garden Street Basin Stormwater Management 

project will treat a 114-acre watershed when completed. The project is 

based on the treatment train concept of utilizing a number of best management practices (BMPs) together or in sequence to provide better storm water 

treatment. The project treatment train is composed of 3 swales, check 

dams, 8 inlet skimmers, and alum injection in a constructed treatment 

pond. Titusville has also completed a retention pond at Sand Point Park 

serving a portion of the Garden Street basin. 

Cocoa has installed baffl e boxes and an underground stormwater collection reservoir in Riverfront Park. Stormwater treated with this system is 

100 Water Quality Assessment Report: Indian River Lagoon
generated in an older section of downtown. Instead of being discharged to 

the IRL lagoon system, stormwater collected in the reservoir is sent to the 

city’s wastewater treatment plant to supplement the supply of reuse water.

Habitat restoration is an important component in the overall restoration of the IRL lagoon system. Large tracts of coastal mangrove wetlands 

were previously impounded for mosquito control. About 14,393 acres of 

these impounded coastal wetlands have been reconnected to the lagoon, 

largely through the SWIM Program, but about another 5,000 acres remain 

impounded (Brockmeyer, 2005). Most of the remaining impounded wetlands are on federally owned property within the Merritt Island National 

Wildlife Refuge. 

Waters will not be placed on the Verifi ed List if the Department 

receives reasonable assurance that existing or proposed projects and/or 

 programs are expected to result in the attainment of water quality standards 

or consistently improve water quality over time. Appendix D contains 

more detailed documentation of the requirements for reasonable assurance. 

For this planning unit, no management plans or projects complying with 

the Department’s guidance for reasonable assurance have been provided for 

the list of impaired waters.

• North Central Indian River Lagoon Planning Unit

General Description

The North Central IRL Planning Unit covers about 196.4 square miles 

in Brevard County and extends from just north of Melbourne, south to 

the St. Sebastian River near Micco. It contains 24 waterbody segments 

(WBIDs). Major waterbodies in the planning unit are the Indian River 

Lagoon and the coastal Atlantic beaches and nearshore coastal waters. 

Tributaries to the planning unit include the Eau Gallie River, Crane 

Creek, and Turkey Creek. Urbanized areas in the planning unit include 

 Melbourne, Palm Bay, and the beachside communities of Melbourne 

Beach, Indialantic, and Indian Harbour Beach.

Water Quality Summary

Of the 24 waterbody segments in the North Central IRL Planning 

Unit, 16 segments have suffi cient data for assessment. Of these, 12 are 

 verifi ed impaired for at least 1 parameter assessed, 4 remain on the Planning List, and none meet standards.

Data from 143 water quality monitoring stations were used for assessment of impairment. Figure 3.7, a composite map of the planning unit, 

shows waters on the 1998 303(d) list, the Planning List and Verifi ed List, 

and potential pollution sources. Table 3.7 summarizes the water quality 

assessment status of all waterbody segments in the planning unit.

Several waterbody segments are impaired, or are exceeding state water 

quality criteria, for metals. The Eau Gallie River is impaired for copper. 

Iron levels exceed the state water quality criterion in Crane Creek and 

the Eau Gallie River. After carefully examining the iron ground water 

concentration, ground water and surface water interaction, iron rich soils, 

and possible iron contributions from golf courses, citrus groves, and some 

landfi ll sites in the general area, the elevated iron concentrations in Crane

Creek and the Eau Gallie River are believed to be a natural condition for 

which TMDLs will not be developed. All coastal waterbody segments in 

the planning unit are impaired for mercury in fi sh. 

The mainstem waters of the Indian River (WBIDs 2963A and 2963B) 

are listed for nutrients based on seagrass information (other information). 

The Eau Gallie River, Crane Creek, Turkey Creek, and the Indian River 

above Melbourne Causeway are impaired for DO. 

Average annual loadings of nutrients and TSS have shown substantial 

increases since 1943. The estimated 1995 annual loadings of TSS and 

nutrients are 3 to 6 times higher than the North IRL and 6 to 15 times 

higher than either Banana River or Mosquito Lagoon. Tributary watersheds contribute a substantial portion of the nutrient and TSS loads. The 

Crane Creek watershed has the highest areal loading rate (as pounds/

acre/year) of all the subbasins or watersheds in the IRL Basin. Loadings 

continue to increase as the watershed urbanizes. The pollutant loadings 

from tributaries have had detrimental effects on the IRL (Steward et al., 

2003). Water quality improvement projects and activities that will result 

in decreased loadings are summarized in the Water Quality Improvement 

Plans and Projects section.

Permitted Discharges and Land Uses

Point Sources: There are 44 permitted point source discharges, 1 

Superfund site, 1 delineated ground water contamination area, and 4 landfi lls in this planning unit. 

Of the 44 permitted discharges in the planning unit, 19 are domestic 

wastewater, 14 are industrial wastewater, 5 are from concrete batch plants, 

and 6 are industrial stormwater. The largest domestic wastewater discharges in the planning unit are 8 mgd from the Brevard County Utilities 

South Beaches facility, 5.5 mgd from the Melbourne Grant Street facility, 

and 5.0 mgd from the D. B. Lee facility. 

An active Superfund site is located in Palm Bay. The Harris Corporation Superfund site is listed because volatile organic compounds used in 

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. 4Parameters in bold meet the Verified List evaluation criteria, Section 62-303.400, F.A.C. 5Parameters in italics are in Category 4 (a, b, or c) waters that do not require TMDL development. 6The assessment categories listed in this column represent the status of each WBID as a whole, based on multiple parameters. 

The hierarchy for 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 total coliforms as 

Category 5, fecal coliforms as Category 3c, and coliforms–shellfish as Category 2, the single assessment call for the WBID is 

Category 5.

steel, metal, and electrical processing were found in ground water supply 

wells in the General Development Utilities Port Malabar wellfi eld. The site 

was placed on the National Priorities List (NPL) in July 1987 and is undergoing remediation to remove organics from ground water (Department, 

2005d). The four landfi lls are located in Melbourne. Two are active solid 

waste transfer stations and the others are closed landfi lls. 

Figure 3.7 shows the locations of these discharges in the planning 

unit. Appendix G lists the basin’s domestic and industrial surface discharge facilities, along with their permitted fl ows, by planning unit. It also 

lists Superfund sites and landfi lls or solid waste facilities by planning unit.

Nonpoint Sources: Based on land use data collected and delineated from 2000 aerial photography, water and wetlands cover more than 

55 percent of the planning unit. Urban and built-up land uses occupy 

24.6 percent of the basin’s area. High and medium density residential 

housing account for more than half of the urban land uses in the planning unit. Other land uses include upland forest (8.8 percent), represented largely as pine fl atwoods (8.5 percent) and rangeland (0.3 percent). 

Table H.4 in Appendix H provides detailed summary information on land 

uses in the planning unit.

Different land uses are associated with nonpoint source pollutant 

discharges and eroded sediments. In urban areas, stormwater discharges 

are managed through MS4 permits. Melbourne, West Melbourne, Satellite 

Beach, Indian Harbour Beach, Indialantic, and Palm Bay are covered 

under Phase 2 of MS4 permitting.

Ecological Summary

The condition of seagrasses in this planning unit is generally poorer 

than in the more northern planning units. Some of the poorest conditions 

and coverage of seagrasses in the IRL system are found in the Melbourne 

area (segments IR9–12), based on 1991–1996 data. Much of this area of 

the IRL is poorly fl ushed and receives comparatively large infl ows of fresh 

water and pollutant loadings, factors that contribute to the poorer condition of seagrasses. The extent of seagrass coverage in this part of the IRL 

fl uctuates more widely than in other sections of the lagoon. 

More recent analysis of seagrass data collected from 1998 to 2003 indicates that the condition of seagrasses in segments IR9–12 have improved 

enough to be ranked as fair (Steward, 2006). Segments to the south of 

Melbourne have improved enough to be ranked as good (Steward, 2006). 

Although seagrass coverage in some segments was improved in the last 

decade, the seagrass depth-limit in none of these segments has reached the 

full restoration target. Therefore, all of the mainstem waterbody segments 

in the North Central IRL Planning Unit were assessed as being impaired 

for nutrients based on seagrass information.

The current condition of seagrass beds in this planning unit is further 

assessed and summarized in the Seagrass Assessment section of this 

chapter based on information provided by the SJRWMD (Steward and 

Green, 2006). 

Much of the muck deposited in the IRL, about 65 percent, is located 

in the central part of the lagoon (Steward et al., 2003). Studies by Trefry 

106 Water Quality Assessment Report: Indian River Lagoon
et al. (1990) indicated that a substantial portion of the muck has been 

deposited over the past 40 years. Tributaries like the Eau Gallie River, 

Crane Creek, and Turkey Creek act as sediment traps and have over the 

years accumulated large deposits of muck. Additional muck has been 

deposited in the Intracoastal Waterway, other channels and turning basins, 

and dredged holes and causeway borrow pits. The muck at the bottom of 

the lagoon and its tributaries is easily resuspended, resulting in increased 

turbidity, reduced light penetration, increased oxygen demand, and release 

of nutrients to the water column. 

Water Quality Improvement Plans and Projects

Numerous water quality and habitat improvement projects have been 

undertaken or are currently planned in this planning unit (Appendix C). 

Financial support for projects was provided by the SJRWMD, Brevard 

County Stormwater Utility, local governments, and the IRLNEP. Project 

information summarized in this section was obtained from the IRL SWIM 

Plan (Steward et al., 2003), Brevard County Stormwater Utility Program 

(Powers, 2006), and by personal communication with Bob Day with the 

IRLNEP (2005). Information about specifi c projects is organized by contributing tributary watershed. Stormwater retrofi t projects discussed cover 

the time period from 1995 to 2005.

The Turkey Creek watershed is a substantial source of loading to the 

IRL lagoon system. The largest and most signifi cant load reduction project 

under way in the Turkey Creek watershed is the C-1 rediversion project. 

This project is expected to help Turkey Creek meet PLRGs for nutrient and 

suspended solids reductions (Steward et al., 2003).

The purpose of the C-1 rediversion project is to divert the discharge 

from Melbourne–Tillman Water Control District’s C-1 Canal westward 

toward the Upper St. Johns River Basin. The canal was built to extend 

the Turkey Creek watershed into the Upper St. Johns River Basin to drain 

marshes with the result of creating suitable land for agriculture. Afterstorm discharges through the canal into Turkey Creek could reach 500 

mgd (Steward et al., 2003). The increased volumes of fresh water discharged through Turkey Creek to the IRL lagoon system caused a lowering of salinity in the lagoon, added large loads of nutrients, contributed 

to the decline of the hard clam fi shery, and have had a negative impact on 

 seagrasses.

The C-1 rediversion project is being constructed by the SJRWMD 

within the canal right-of-way of the Melbourne–Tillman Water Control 

District. Water returned to the St. Johns River will be stored in the C-1 

Retention and Detention areas before being pumped into a created wetland 

treatment system, called the Sawgrass Lake Water Management Area, for 

treatment prior to release into the St. Johns River.

The management of stormwater runoff is an important tool for reducing nutrient and sediment loads to Turkey Creek and ultimately the IRL 

lagoon system. The city of Palm Bay has undertaken numerous past and 

current stormwater management efforts to address the problems of nutrient 

and sediment loading. Improvements are proposed for the Perimeter Canal 

to reduce sediment discharges to the lower reach of Turkey Creek. TSS and 

Water Quality Assessment Report: Indian River Lagoon 107
nutrient loads to Turkey Creek will be reduced with the completion of a 

series of 3 stormwater ponds and treatment of stormwater outfalls from the 

Turkey Creek subdivision. Treatment of runoff from subdivisions in Palm 

Bay (Palm Bay units 38 and 40) with ponds will add further reductions. 

The reduction of runoff from the Turkey Creek subdivision located along 

the Mandarin Ditch will reduce fl ooding and erosion of the ditch banks. 

Additional stormwater improvement projects for the Turkey Creek 

watershed were completed in the Palm Bay area before 2001. Wet detention ponds constructed in Basins 1 and 7 treat runoff from a 100-acre 

residential and commercial development. This project also treats runoff 

that discharges directly into the IRL lagoon system. Baffl e boxes were 

installed on Norwood Street in Palm Bay and on Corey Road in neighboring Malabar. 

The Crane Creek watershed covers about 21 square miles and drains 

a developing urban area. Crane Creek receives stormwater runoff from 

Melbourne, Melbourne Village, West Melbourne, and parts of unincorporated Brevard County. Brevard County’s Stormwater Utility Department 

contracted the development of a stormwater master plan for this watershed and the Hickory Ditch watershed in 2002 (Post, Buckley, Shuh, and 

Jernigan, Inc. [PBS&J], 2002) with fi nancial support from Melbourne and 

SJRWMD (Brevard County Stormwater Utility Department, 2006). The 

plan helps to identify potential water quality BMPs, areas of the watershed 

with fl ooding problems, and actions that could be used to increase ground 

water recharge. Design and permitting is currently under way for the 

St. Johns Outfall Project identifi ed in the report. This project consists of 

upgrading culverts and ditches to divert fl ow from the IRL lagoon system 

to the St. Johns River. An existing borrow pit will be modifi ed to provide 

treatment prior to discharge to the St. Johns River.

Stormwater retrofi ts are an important part of the overall strategy 

to reduce stormwater runoff and associated pollutant loads within the 

Crane Creek watershed. Reduction of sediment loads to the M-1 Canal 

and ultimately Crane Creek will be achieved with the Melbourne Village 

Stormwater and Sediment and Erosion Control Project. A previous sediment control project in Melbourne’s Goode Park Terrace area resulted in 

the paving of dirt roads and the construction of swales to treat runoff from 

residential development. Brevard County had also previously treated and 

improved drainage from Dove Street. The city of West Melbourne completed installation of a pipe in the Shannon Avenue ditch to reduce erosion 

in the ditch and prevent transport of sediment to the M-1 Canal. A baffl e 

box was constructed to treat the discharge of the pipe to collect sediment 

before it could enter the M-1 Canal.

A Stormwater Master Plan was completed for the Upper Eau Gallie 

River watershed in 2000 (PBS&J, 2000). The plan identifi ed areas of 

the watershed needing additional stormwater quantity and quality controls. As part of the execution of that plan, drainage improvements to 

alleviate fl ooding have been made where Wickham Road crosses the Eau 

Gallie River. The Wickham Park Detention Pond was constructed to treat 

 stormwater runoff. 

108 Water Quality Assessment Report: Indian River Lagoon
Numerous other stormwater improvement projects initiated by Brevard 

County and local city governments are targeted at removing nutrient and 

sediment loads directly from the IRL lagoon system. 

• Brevard County is utilizing a dry retention pond to treat residential 

development on Barracuda Avenue in Melbourne Beach. 

• The city of Melbourne Beach has plans for stormwater treatment 

train methodologies at eight city street intersections as part of the 

Melbourne Beach Pedway Project. The city has also installed baffl e 

boxes on Ocean Drive to treat runoff from residential and commercial development. 

• In the Melbourne Beach area, the Brevard County Storm water 

 Utility Department assisted Gemini Elementary School with 

 construction of dry retention ponds and swales.

• Brevard County has completed construction of a stormwater pond 

and wetlands to treat runoff from Melbourne Shores prior to 

 discharge to the lagoon.

• Indialantic has constructed a swale system between Fourth Avenue 

and Indian River Drive to treat runoff from 30 acres of medium-tohigh density residential land use and purchased a street sweeper. 

Muck accumulated in parts of the IRL lagoon system contributes 

 nutrients and resuspended sediment to the water column. Eliminating 

muck deposits from the waters of this planning unit will help restore water 

quality and improve the biological condition of seagrasses in the IRL 

lagoon system. The strategy to handle muck is twofold: remove existing large accumulations and prevent further upland erosion of sediments. 

Many of the aforementioned stormwater improvement projects address the 

second part of this strategy by reducing soil erosion. Muck deposits were 

removed from Crane Creek in 1998 and from Turkey Creek in 2001. A 

conceptual dredge removal and disposal plan was completed for the Eau 

Gallie River. Other parts of the planning unit that are under consideration 

for muck removal projects include the Intracoastal Waterway and a 10-mile 

stretch of the lagoon from about the Eau Gallie Causeway (State Road 518) 

south to Turkey Creek.

Efforts to enhance the amount of coastal wetland acreage include the 

reconnection of mosquito impoundments and planting of red mangrove 

seedlings. There are an estimated 3,300 acres of impounded coastal wetlands located in the central IRL lagoon system (Steward et al., 2003). Out 

of that total, 2,710 acres have been reconnected to the IRL (Brockmeyer, 

2005). Some of the reconnected mosquito impoundments are located at 

the southern end of this planning unit, though the greater acreage of reconnected impoundments is located in the South Central IRL Planning Unit. 

Planting of red mangrove seedlings has been accomplished at numerous 

locations within the planning unit. 

Waters will not be placed on the Verifi ed List if the Department 

receives reasonable assurance that existing or proposed projects and/or 

Water Quality Assessment Report: Indian River Lagoon 109
 programs are expected to result in the attainment of water quality standards or consistently improve water quality over time. Appendix D 

contains more detailed documentation of the requirements for reasonable 

assurance. For this planning unit, no management plans or projects complying with the Department’s guidance for reasonable assurance have been 

provided for the list of impaired waters.

• South Central Indian River Lagoon Planning Unit

General Description

The South Central IRL Planning Unit covers about 338 square miles 

in South Brevard County and Indian River County. It extends from 

the Sebastian Inlet and Sebastian River near Micco, south to the Indian 

River County/St. Lucie County line. It contains 32 waterbody segments 

(WBIDs). Major waterbodies in the planning unit are the IRL and the 

coastal Atlantic beaches and nearshore coastal waters. Tributaries to the 

planning unit are the Sebastian River, C-54 Canal, Main Canal, North 

Canal, South Canal, and Fellsmere Canal. Drainage from the Indian River 

Farms Water Control District North, South, and Main Canals discharges 

to the IRL in this planning unit. Cities in the planning unit include 

 Sebastian and Vero Beach.

Water Quality Summary

Of the 32 waterbody segments in the South Central IRL Planning 

Unit, 25 segments have suffi cient data for assessment. Of these, 23 are 

 verifi ed impaired for at least 1 parameter assessed, 2 remain on the 

 Planning List, and none meet standards.

Data from 162 water quality monitoring stations were used for assessment of impairment. Figure 3.8, a composite map of the planning unit, 

shows waters on the 1998 303(d) list, the Planning List and Verifi ed List, 

and potential pollution sources. Table 3.8 summarizes the water quality 

assessment status of all waterbody segments in the planning unit.

By far the most prevalent impairment in this planning unit is mercury 

in fi sh, affecting 18 of the 23 listed segments. This includes 6 segments 

of the IRL and 12 coastal segments. Consumption advisories have been 

issued for the affected segments. The second most prevalent impairment in 

the planning unit is DO, with 7 segments affected. 

Two coastal beaches, Humiston Beach and Sexton Plaza, are impaired 

for fecal coliforms based on beach closure advisories issued by DOH. 

Three other segments (North Canal, Main Canal, and South Canal) are 

impaired for fecal coliforms based on assessment water quality data. 

All waters in the South Central IRL are impaired for nutrients based 

on seagrass information provided by the SJRWMD (Steward and Green, 

2006). Average annual loads of nutrients and TSS have shown substantial 

increases since 1943. Spatial differences in nutrient and TSS loads have 

also been observed. The estimated 1995 annual nutrient and TSS loads in 

the South Central IRL were 3 to 6 times higher than in the North IRL and 

6 to 15 times higher than in either Banana River or Mosquito Lagoon. 

Tributaries contribute substantial loads to the IRL and have had 

 detrimental effects on it (Steward at al., 2003). The Sebastian River

contributes greater nutrient and TSS loads to the IRL than either Crane 

Creek or Turkey Creek. Water quality improvement projects and activities 

that will result in decreased loadings are summarized in the Water Quality 

Improvement Plans and Projects section. 

Permitted Discharges and Land Uses

Point Sources: There are 38 permitted discharges in the planning 

unit, 11 landfi lls, 1 Superfund hazardous waste site, and 1 delineated 

ground water contamination area. 

Of the 38 permitted discharges, 12 are domestic wastewater, 3 are 

from concrete batch plants, and 23 are industrial wastewater. The largest 

industrial wastewater discharge in the planning unit is 181 mgd of cooling 

water from the Vero Beach Municipal Power Plant. The largest domestic 

wastewater discharges are from the Vero Beach Wastewater Treatment 

Plant (4.5 mgd) and the Indian River County Utilities Wastewater Treatment Facilities (cumulative 6 mgd).

There are two active household solid waste disposal landfi ll sites in the 

planning unit and the others are closed; ground water is being monitored 

onsite. 

The Piper Aircraft active Superfund hazardous waste site is located in 

Vero Beach. The delineated ground water contamination site associated 

with Piper Aircraft is contaminated by trichloroethylene (TCE). Onsite 

monitoring determined that the TCE was migrating off the Piper property 

in the direction of a down gradient public supply well and posed a potential threat to private wells in the area. The site was placed on the NPL on 

February 16, 1990, and is being remediated to remove the TCE as part of a 

Consent Decree between EPA and Piper Aircraft (Department, 2005e).

Figure 3.8 shows the location of these discharges in the planning unit. 

Appendix G lists the basin’s domestic and industrial surface discharge 

facilities, along with their permitted fl ows, in the planning unit. It also 

lists Superfund hazardous waste sites, landfi lls or solid waste facilities, and 

hazardous waste sites.

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. 4Parameters in bold meet the Verified List evaluation criteria, Section 62-303.400, F.A.C. 5Parameters in italics are in Category 4 (a, b, or c) waters that do not require TMDL development. 6The assessment categories listed in this column represent the status of each WBID as a whole, based on multiple parameters. 

The hierarchy for 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 total coliforms as 

Category 5, fecal coliforms as Category 3c, and coliforms–shellfish as Category 2, the single assessment call for the WBID is 

Category 5.

Water Quality Assessment Report: Indian River Lagoon 115
Nonpoint Sources: Based on land use data collected and interpreted from year 2000 aerial photography, predominant land uses in 

the planning unit are water and wetlands (33.4 percent) and agriculture 

(24 percent). Atlantic nearshore coastal waters occupy 17.8 percent of the 

planning unit area. Citrus accounts for 16.9 percent of the agricultural 

area (almost 34,000 acres) followed by improved pasture (3.5 percent) and 

fallowed cropland (1.2 percent). Urban and built-up areas occupy another 

19 percent of the planning unit’s area, with most urban land classifi ed 

as low and medium density residential development. Important recreational and conservation lands in the planning unit include Pelican Island 

National Wildlife Refuge, Sebastian Inlet State Recreational Area, and 

Sebastian Buffer Preserve. Table H.5 in Appendix H contains summary 

and detailed information on land uses in the planning unit.

Different land uses are associated with nonpoint source pollutant discharges and eroded sediments. In urban areas, stormwater discharges are 

managed through MS4 permits. Vero Beach is covered under Phase 2 of 

MS4 permitting.

Ecological Summary

All seven species of seagrasses that grow in the IRL are found in the 

South Central IRL Planning Unit south of Sebastian Inlet. Seagrasses at 

and near Sebastian Inlet generally are in good condition. Based on the 

1991–1996 assessment data, the area of the lagoon in the vicinity of Vero 

Beach has some of the poorest seagrass conditions (segments IR16–20). 

More recent analysis of seagrass data (1998 to 2003) indicates that the 

condition of seagrasses near Vero Beach have improved enough to receive a 

good ranking (Steward, 2006).

Although seagrass coverage in some segments was improved in the last 

decade, the seagrass depth-limit in none of these segments has reached the 

full restoration target. Therefore, all of the mainstem waterbody segments 

in the South Central IRL were assessed as being impaired for nutrients 

based on seagrass information.

The current condition of seagrass beds in this planning unit is further 

assessed and summarized in the Seagrass Assessment section of this 

chapter based on information provided by the SJRWMD (Steward and 

Green, 2006). 

The lower reach of the Sebastian River has over the years acted as 

a sediment trap collecting muck composed of upland soils and organic 

matter. There are muck deposits in the Intracoastal Waterway near Vero 

Beach, in dredge holes, borrow pits by causeways, and other channels and 

turning basins. Much of the muck deposited in the IRL, about 65 percent, 

is located in the central part of the lagoon (Steward et al., 2003). Studies 

by Trefry et al. (1990) indicated that a substantial portion of the muck has 

been deposited over the past 40 years. Tributaries act as sediment traps and 

have over the years accumulated large deposits of muck. The muck at the 

bottom of the lagoon and its tributaries is easily resuspended, resulting in 

increased turbidity, reduced light penetration, increased oxygen demand, 

and release of nutrients to the water column. 

116 Water Quality Assessment Report: Indian River Lagoon
Water Quality Improvement Plans and Projects

Numerous water quality and habitat improvement projects have been 

undertaken or are currently planned in this planning unit (Appendix C). 

Financial support for projects has come from the SJRWMD, Brevard 

County Stormwater Utility, Indian River County, local governments, 

and the IRLNEP. Examples of projects summarized in this section were 

obtained from the IRL SWIM Plan (Steward et al., 2003), Brevard County 

Stormwater Utility Program (Powers, 2006), and by personal communication with Bob Day with the IRLNEP (2005). Stormwater retrofi t projects 

discussed cover the time period from 1995 to 2005.

Agriculture, primarily citrus, is a more prevalent land use in the South 

Central IRL Planning Unit compared with the other planning units. 

BMPs were adopted in June 2002 for Indian River Citrus (Chapter 5M-2, 

F.A.C.) in an effort to better manage water use in groves and protect water 

quality. There is currently an active successful effort between the DACS, 

the University of Florida Institute of Food and Agricultural Sciences 

(IFAS), and citrus growers to implement these BMPs. IFAS has instituted 

a Canal Watch Program to monitor the water quality of canals receiving 

drainage from citrus groves in Indian River, Martin, and St. Lucie Counties 

and to use those data to identify and investigate locations with higher than 

expected loadings (http://citrusbmp.ifas.ufl .edu/indianriver/canalWatch 

.html).

Discharges from the Indian River Farms Water Control District, 

 delivered through North, Main, and South Canals, impact about 12 miles 

of the southern part of the IRL. Water quality and the condition of seagrasses in the area have historically been poor compared to other segments 

of the lagoon. Starting in 2001, responsible agencies including Indian 

River County, SJRWMD, Indian River Farms Water Control District, Vero 

Beach, and the Indian River County IFAS Extension Offi ce organized to 

develop a water management plan. Other agencies may be asked to partner 

in the effort in the future. The fi nal plan will need to balance restoration 

needs of the IRL lagoon system and drainage needs. 

The Indian Farms Drainage District Signage Project is an Indian River 

County project directed at increasing public awareness of the connection 

of the Indian River Farms Canals to the IRL lagoon system. Educational 

signage will be placed throughout the Indian Farms Drainage District in an 

effort to discourage the dumping of debris into Drainage District canals. 

The Sebastian River watershed covers approximately 172 square miles 

and contributes greater loadings of nutrients and suspended solids to the 

IRL lagoon system than either Crane Creek or Turkey Creek. Several water 

resource planning efforts and water quality improvement projects are under 

way or proposed for this watershed. The implementation of plans and 

projects is anticipated to lead to improved fl ood control, improved salinity 

maintenance, and reductions in nutrient and suspended solids loads. 

 Individual plans and projects are specifi c to geographic area and sponsoring 

entity. The fi nal goal of all planning efforts is to meet salinity and PLRG 

targets for the Sebastian River and the IRL lagoon system. Summaries 

Water Quality Assessment Report: Indian River Lagoon 117
of major water quality improvement projects and planning efforts in the 

 planning unit are as follows: 

• The lower reach of the Sebastian River is a sediment trap accumulating a thick deposit of muck. The dredging proect is currently 

underway and will continue through November of 2008, the start of 

manatee migration. The fi nal season of dredging will begin again in 

April of 2009.

• Hydrologic restoration of the Herndon Swamp is proposed. 

 Herndon Swamp is located in the Sebastian Buffer Preserve and is 

the historical headwater of the North Prong of the Sebastian River 

(SJRWMD, 2006a). 

• The city of Sebastian has prepared a surface water master plan that 

addresses pollutant reduction and fl ood control. Completed parts of 

the plan included the improvement of a water control structure on 

the Elkam Canal and a stormwater treatment pond that treats the 

Stonecrop area drainage. 

• SJRWMD is assisting the city of Sebastian with the design and 

construction of the Sebastian Stormwater Park in the southern part 

of the city, which will treat runoff from a 1,300 acre residential area 

(Steward et al., 2003). Recreational facilities will be included in 

the park. Sebastian will assume operation and maintenance of the 

park facility.

• Within the North Prong Sebastian River drainage, 496 acres of land 

located near the Sottile Canal were purchased by the SJRWMD. 

A large portion of that acreage has been set aside for a stormwater 

detention area to treat runoff from projected build-out of the Barefoot Bay Community and for dredge spoil disposal from future 

dredging of the Sebastian River. 

• Water resource planning is in progress between SJRWMD, U.S. 

Army Corps of Engineers, Sebastian River Water Control District, 

and Fellsmere Water Control District. These planning efforts are 

expected to result in improved stormwater management, salinity 

control, water level management, and erosion control.

• Indian River County has completed a stormwater improvement 

project at Vero Lake Estates. The Vero Lake Estates project involved 

a redesign of upland treatment ponds into a wet detention system 

including improvements to swales. The project treats 3,871 acres of 

residential development and reduces loadings to the South Prong of 

Sebastian River and ultimately the IRL lagoon system. 

Additional stormwater improvement projects initiated by local governments will contribute to direct reductions in nutrient and sediment loads 

to the IRL lagoon system. In an effort to reduce sediments, Indian River 

County is paving dirt roads and constructing swales to control sediments in 

road runoff that currently discharges directly into the IRL lagoon system. 

118 Water Quality Assessment Report: Indian River Lagoon
The cities of Vero Beach and Sebastian have installed baffl e boxes to reduce 

sediment loads. The baffl e box installed in Sebastian treats runoff from 

Main Street in the older downtown part of the city. Sebastian has plans to 

add another baffl e box on Indian River Drive. This newer baffl e box will 

be designed to remove nutrients in addition to sediment from a 96-acre 

drainage area. The city of Fellsmere has developed a Master Drainage 

Plan, paved State Street, and constructed a retention pond to serve the 

project area. Indian River County has initiated the Gifford and Roseland 

community drainage improvement projects to address storm water runoff 

from mixed residential and commercial development. Gifford is located 

north of Vero Beach and Roseland is just south of the Sebastian River. The 

Gifford improvement project requires construction of a 4.5-acre detention 

lake and swale. The Roseland element of the project will construct a wet 

detention pond to treat stormwater runoff before discharge into Collier 

Creek. Brevard County’s Stormwater Utility Program constructed stormwater detention ponds on Church Street and Fleming Road near Micco for 

treatment of stormwater runoff and for control of fl ooding and installed 

 exfi ltration piping and sediment traps along Main Street in Micco.

Habitat restoration and invasive plant management activities are 

proposed for Nelson’s Island, Wabasso Causeway Park, and Pelican Island. 

Shoreline stabilization reduces the amount of sediment that can enter the 

IRL lagoon system. The Coastal Resources Group has primary responsibility for removing exotic vegetation and planting cord grass along the 

shoreline of Nelson’s Island. The U.S. Fish and Wildlife Service is taking 

the lead in the restoration and stabilization of Pelican Island. Indian River 

County has planted native vegetation and constructed coquina revetments 

to reduce erosion and stabilize the shoreline at the Wabasso Causeway Park. 

Efforts to enhance the amount of coastal wetland acreage include the 

reconnection of mosquito impoundments, public acquisition of wetlands, 

and planting of red mangrove seedlings. There are an estimated 3,300 

acres of impounded coastal wetlands located in the central IRL lagoon 

system (Steward et al., 2003). Out of that total, 2,710 acres have been 

reconnected to the IRL (Brockmeyer, 2005). Most of the acreage of reconnected impoundments is located in the South Central IRL Planning Unit. 

More than 4,000 acres of wetlands and their adjacent uplands in the southern part of the North Central IRL Planning Unit and the South Central 

IRL Planning Unit are identifi ed for purchase by the Blueway Program 

(Steward et al., 2003). Planting of red mangrove seedlings has been accomplished at numerous locations within the planning unit. 

Waters will not be placed on the Verifi ed List if the Department 

receives reasonable assurance that existing or proposed projects and/or 

 programs are expected to result in the attainment of water quality standards 

or consistently improve water quality over time. Appendix D contains 

more detailed documentation of the requirements for reasonable assurance. 

For this planning unit, no management plans or projects complying with 

the Department’s guidance for reasonable assurance have been provided for 

the list of impaired waters.

Chapter 4: Evaluation of Ground Water and 

Geologic Influences on Impaired Waterbodies

This chapter evaluates the potential infl uences of ground water and 

natural geologic, soil, and/or ground water chemistry on surface water 

 quality in the Indian River Lagoon (IRL) 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 (IWR) listing thresholds 

due to natural conditions. The listing parameters receiving scrutiny include 

nutrients (chlorophyll a), dissolved oxygen (DO), and iron. The available 

ground water data used for this assessment are limited by both the number 

of observations and the period of record (generally 1989–2003).

Geology, Soil, and Ground Water

Setting 

The hydrogeology of the basin is very heterogeneous. Three main 

aquifers—the Floridan, intermediate, and surfi cial aquifers—underlie 

the IRL Basin. The surfi cial aquifer is composed of interbedded lenses of 

marine, fi ne to medium sand, shell, and silty clay of Pliocene and Upper 

Miocene ages that lie on top of a confi ning layer, consisting of clay and 

other less-permeable material of the Hawthorn Group. The thickness 

of the surfi cial aquifer generally increases toward the coast and is about 

100 feet but can be as much as 400 feet in portions of the basin.

The confi ning unit separates the surfi cial and underlying Floridan 

aquifer systems and in parts of the basin can also include the intermediate aquifer system. The intermediate aquifer consists of more-permeable 

lenses of sand, shell, and limestone that occur within the Hawthorn Group 

confi ning layer, which is thinner or absent in the northern portions of the 

basin. In these northern areas, this allows a greater exchange of ground 

water between the Floridan and surfi cial aquifers and the IRL (Toth, 1987). 

In the central portion of the basin, the Floridan aquifer is completely 

confi ned by the Hawthorn Group material, which is approximately 100 feet 

thick. The upper Floridan aquifer is composed of the Ocala Limestone 

and in some parts, the Avon Formation. The Ocala Limestone has high 

permeabilities that are increased along bedding planes and by fractures 

and conduits.

Ground water fl ow in the Floridan aquifer is generally west to east 

toward the Atlantic Ocean. The potentiometric surface of the Floridan 

aquifer ranges from 0 to 35 feet above mean sea level along the coastline. 

Water Quality Assessment Report: Indian River Lagoon 121
The water table of the surfi cial aquifer system is shallow, and its gradient 

roughly approximates the land surface topography (Healy, 1982). The 

water table usually is deeper in Martin County (8 to 10 feet below the land 

surface) (Healy, 1982).

There is also a vertical exchange of ground water between aquifers, and 

most of the basin is a ground water discharge area for the Floridan aquifer. 

Signifi cant variations in ground water levels occur seasonally, and a longterm decrease in the potentiometric surface is largely attributed to increased 

ground water withdrawals. The potentiometric surface elevations are above 

sea level for the entire length of the IRL. This, combined with the general 

lack of a confi ning unit in some areas, also makes much of the IRL a 

potential zone of submarine ground water discharge.

The soils in the basin—predominantly Entisols, marsh Spodosols, 

and poorly drained coastal Alfi sols and Spodosols—are among the most 

preferred soils for citrus. They are composed of sandy materials with low 

organic content (Obreza and Collins, 2002). Some of these soils have a 

chemical mechanism to bind phosphorus due to a differing amount of silt 

and clay. Other soils dominated by quartz sand lack appreciable amounts 

of these silts and clays, but in many cases the sand is coated with iron 

and/or aluminum, which also have some capacity to sorb phosphorus.

Ground Water–Surface Water Interactions 

The interaction between ground water and surface water is signifi -

cant in the IRL Basin. Natural streams are supported by ground water 

discharge. Basefl ow separation analyses performed by the Florida Department of Environmental Protection (Department) for 9 streams across the 

basin showed ground water contributions of between 54 and 71 percent of 

the total fl ow (Tinsley, Li, and Gao, 2007). Canals intersect the surfi cial 

 aquifer and drain large areas to artifi cially suppress the water table and 

make more land available for agricultural and urban development. Water 

in major canals is manipulated to provide aquifer recharge and prevent 

saltwater intrusion near the coast. In other near-coastal areas and in the 

 vicinity of canals that do not have salinity control structures, saltwater 

intrusion into the surfi cial aquifer occurs. 

The basin includes areas of artesian ground water fl ow from the Floridan aquifer. The amounts of upward fl ux through seepage, springs, sinks, 

or unplugged wells to the surfi cial and intermediate aquifers and to surface 

waters (including points offshore beneath the Atlantic Ocean) depend on 

the thickness and the extent of breaching of the overlying confi ning layer. 

Thus surface water in the basin could consist of a mixture of direct precipitation, surface runoff, seepage from the surfi cial aquifer, and discharge 

from the Floridan aquifer. Ground water seepage into streams in the basin 

is appreciable.

The direct submarine discharge of ground water to the IRL itself may 

be signifi cant. Studies have shown that the submarine discharge of water 

can transport nutrients from agricultural lands (Simmons, 1992; Gallagher, 

Dietrich, Reay, Hayes, and Simmons, 1996) and residential septic tanks 

(Weiskel and Howes, 1992) to coastal marine waters. Hydrogeological 

studies by the U.S. Geological Survey (USGS) have indicated that in the 

122 Water Quality Assessment Report: Indian River Lagoon
Upper IRL, only 1 to 5 percent of interstitial water is composed of meteoric 

ground water. The remaining 95 to 99 percent is probably recycled lagoon 

seawater. Nutrient concentrations were 3 to 5 times higher in the seepage 

water than the lagoon water, suggesting that submarine ground water discharge could be a critical component of the coastal nutrient budget.

Overview of Ground Water Quality

Ground water quality statistics are presented in Table 4.1 for the 

surfi cial aquifer and Table 4.2 for the Floridan aquifer in each planning 

unit. The data were obtained from the Department’s Oracle-based Ground 

Water Information System (OGWIS) database. Data retrieved from 

OGWIS were for the surfi cial and Floridan aquifer systems. Evaluating 

ground water data in each planning unit with listed surface waters, comparing this information with data on surface waters on the draft Verifi ed 

List, and analyzing other planning-unit-specifi c characteristics may help 

to identify more instances where naturally occurring conditions infl uence 

surface water quality.

Nutrients 

In a recent pollutant load reduction goal analysis for the IRL, the 

St. Johns River Water Management District (SJRWMD) recognized that 

the actual load currently contributed by direct wastewater discharge from 

permitted facilities is, in most cases, a small fraction of the total annual 

external load of nutrients to the lagoon (on the order of 2 percent). The 

bulk of the nutrient load into the system must therefore come from nonpoint sources.

The pollutants responsible for excessive chlorophyll a growth, measured as high chlorophyll a levels in streams and estuaries and high Trophic 

State Index values in lakes, are nitrogen and phosphorus. Both of these 

nutrients exist naturally in the environment, but both can be released by 

anthropogenic activities. Both nitrogen and phosphorus exhibit spatial 

and temporal variability in the IRL Basin. Generally, the basin is mainly a 

phosphorus-limited system, with some colimitation based on total nitrogen 

(TN)/total phosphorus (TP) ratios in the North IRL Planning Unit. 

Nitrogen in water is derived from a variety of sources, some natural 

and others due to human activities. Typical anthropogenic sources of 

nitrogen include atmospheric deposition, agricultural and residential 

fertilizers, and domestic wastewater. Based on available data, nitrate and

124 Water Quality Assessment Report: Indian River Lagoon
nitrate+nitrite (both reported as “nitrate”) levels in the surfi cial aquifer 

are not particularly elevated in the northern portions of the basin, but are 

elevated in wells located in the central and southern portions of the basin. 

In contrast, the highest levels of ammonia, ammonia+organic nitrogen, 

and phosphorus in the surfi cial aquifer are found in the northern portion 

of the basin. Signifi cant concentrations of ammonia and organic nitrogen 

were observed in shallow ground water and surface waters in the basin. 

Figure 4.1 shows the distribution of ammonia in the surfi cial aquifer in 

ambient monitoring wells.

Total Kjehldahl nitrogen (TKN) is the combination of organically 

bound nitrogen and ammonia, which are most commonly found at high 

levels in untreated wastewater and are frequently monitored as an indicator of industrial pollution and sewage. Low to moderate levels of ammonia 

and organic nitrogen occur naturally in the environment, and lake and 

stream medians for TKN in Florida are typically higher than 1 milligram 

per liter (mg/L) (Department, 2004). The highest levels of ammonia and 

ammonia+organic nitrogen in shallow ground water in the basin were in 

the Banana River Planning Unit, but ground water concentrations in all 

planning units except Mosquito Lagoon were elevated compared with those 

for the SJRWMD as a whole. The by-planning-unit discussions evaluate 

these conditions in more detail.

In an interagency study using data from 1979 to 2004, the seasonality 

of surface water constituents was researched for the IRL (Qian, Migliaccio, 

Wan, Li, and Chin, 2007). Major water quality indicators (conductivity,

turbidity, color, and chloride) exhibited signifi cant seasonal patterns. 

Almost all nutrient species that included nitrate, ammonia, and phosphorus had identical seasonal patterns of concentrations that were signifi cantly 

greater in the wet than in the dry season (nitrate, ammonia, TKN, phosphate, and total phosphorus). The study fi ndings indicate that nutrient 

delivery to surface waters via wet deposition, runoff, or ground water 

seepage corresponds with rainfall and the associated fl ushing of nutrients. 

The seasonality of nutrient delivery could be related to the application of 

fertilizers for citrus groves and to some extent atmospheric deposition and 

reactions with rainwater.

Citrus farming is a signifi cant land use in this basin and is a potentially 

signifi cant source of nutrients to ground and surface waters. The Florida 

Agricultural Statistics Service reported in 1996 that about 35 percent of 

Florida’s irrigated citrus acreage was in Indian River, Martin, and St. Lucie 

Counties. A USGS study by Crandall (2000) estimated that approximately 

175 to 225 pounds per acre of nitrogen (generally as ammonium nitrate 

or potassium nitrate) are applied annually to groves. Each year about 

one-third of the total annual nitrogen fertilizer is applied in the fall, with 

the remaining two-thirds applied before June (Tucker, Alva, Jackson, and 

Wheaton, 1995) using either dry or a combination of both liquid and dry 

fertilizer. The by-planning-unit discussions evaluate these conditions.

Phosphorus found in ground water and surface water in the basin 

can be from natural sources, natural historical accumulation, more recent 

anthropogenic sources, or a combination of sources. Land use in the vicinity may dictate the extent to which these accumulations are characterized 

Water Quality Assessment Report: Indian River Lagoon 125
Figure 4.1: Ammonia Levels in the Surficial Aquifer in the Indian River Lagoon Basin

126 Water Quality Assessment Report: Indian River Lagoon
as naturally occurring. In agricultural areas, fertilizer applications and 

livestock waste can discharge phosphorus to surface waters via runoff. The 

use of phosphorus-containing fertilizers has been documented for citrus 

farming, which is the predominant agricultural land use in the basin. The 

capacity of the soils in citrus farming areas to adsorb phosphorus varies 

depending on clay and organic content and the coating on soil grains. In 

some areas, phosphorus runoff is more of an issue due to soil characteristics. Also, activities that drain or disturb phosphorus-containing peat and 

muck—such as canal construction or the fl ooding of agricultural fi elds—

may release phosphorus into surface water.

Orthophosphate, which is the soluble, inorganic form of phosphorus most typical of ground water, can be derived from natural geologic 

material, mineralized and released from peat and muck, or leached from 

inorganic fertilizers. Orthophosphate is slightly elevated in the Floridan 

aquifer, while orthophosphate and phosphorus concentrations are much 

higher in the surfi cial aquifer compared with the Floridan aquifer. 

Figure 4.2 shows the distribution of orthophosphate in ground water 

samples from the surfi cial aquifer in ambient monitoring network wells. 

Nitrate and phosphate levels in the counties to the west, representing 

upgradient ground water, are similar to those in the IRL Basin.

Phosphorus and iron have an affi nity for one another, which may 

explain the coincidence of elevated orthophosphate and iron in the surfi cial 

aquifer sampling locations (Figures 4.2 and 4.3). In estuarine systems, 

research indicates that phosphorus adsorbs to sediments enriched with iron 

under aerobic conditions and can be released on burial under anaerobic 

conditions (Pant and Reddy, 2001).

Peat and organic muck are also associated with phosphorus retention 

and are found in the interior marshy areas of the basin that have accreted 

during fl ooded conditions and in stream and lake beds. The organic 

material can be oxidized during dry periods or when wet areas are drained. 

This can result in decreased net phosphorus retention and the conversion 

of organic phosphorus into the more mobile inorganic form, which can be 

subsequently released into the water column (Olila and Reddy, 1997; Pant 

and Reddy, 2001). The fl ooding of soils in previously farmed areas has 

been known to release phosphorus to the water column from residual fertilizer phosphorus adsorbed to the soil (D’Angelo and Reddy, 1994; White, 

Reddy, and Moustafa, 2004). The results of a study in the Lower St. Johns 

Estuary (Malecki, White, and Reddy, 2004) indicate that the internal fl ux 

of dissolved reactive phosphorus (as well as ammonium) from sediments 

may be a signifi cant portion of the total load of these constituents being 

released to surface waters.

Iron

Iron is the metal most typically identified with a natural source, and 

elevated iron concentrations are common in the surfi cial aquifer throughout the state. Generally, iron is found in abundance in organic soils, but 

it can also form as a coating on quartz grains in low organic soils such as 

those in the IRL Basin. Human activities such as mining, soil erosion 

from construction and agricultural sites, the application of iron-containing

Figure 4.3: Iron Levels in the Surficial Aquifer in the Indian River Lagoon Basin

Water Quality Assessment Report: Indian River Lagoon 129
 fertilizer, and the landfi lling of wastes may also cause elevated iron concentrations in ambient waters on a local scale. However, elevated iron on 

a broad, regional scale is due to natural conditions. In an evaluation of 

enrichment of iron in surface waters of the basin, Tinsley et al. (2007) 

found that excessive levels of iron in four waterbodies in the basin were 

naturally occurring.

Elevated concentrations of iron in solution in natural water frequently 

occur along with low pH, low oxidation-reduction potential, and high 

dissolved organic carbon content. The low DO concentrations in ground 

water provide the anoxic setting where iron is in its most mobile form. Iron 

concentrations in the surfi cial aquifer are much higher than in the Floridan 

aquifer by orders of magnitude due to these conditions. The elevated iron 

in the surfi cial aquifer could come from the iron-coated grains in soils 

and also from clays in the underlying material of the Hawthorn Group. 

Upwelling ground water could also possibly transport the soluble iron from 

the Hawthorn to the surfi cial aquifer. The ground water coming from 

anoxic conditions in the aquifers can then interact with surface waterbodies, where the iron can concentrate in organic sediments.

Median concentrations of iron in the surfi cial aquifer wells are elevated 

in all of the basin’s planning units that have data (Table 4.1), suggesting that where ground water to surface water pathways exist, elevated iron 

in ground water is also a source of elevated iron in surface waterbodies. 

Figure 4.3 shows the common occurrence of elevated iron concentrations 

in the basin’s ambient monitoring wells in the surfi cial aquifer. 

Dissolved Oxygen

DO levels can be depressed in surface water systems because of nutrient enrichment and/or biochemical oxygen demand (BOD). The nutrient 

enrichment in shallow ground water in the form of ammonia and organic 

nitrogen and phosphorus was discussed earlier. Low DO can also be 

attributed to poor water circulation caused by stream channelization or 

disruption in fl ows. In addition, ground water infl ows, where signifi cant, 

can lower DO levels in surface water systems. DO levels in ground water 

are always naturally low, and thus low DO is a natural condition in ground 

water in all of the basin’s planning units (Tables 4.1 and 4.2). Also, 

ammonia and organic nitrogen and phosphorus in ground water discharges 

could contribute to nutrient loads in some surface waters. Orthophosphate 

and phosphorus medians in the surfi cial aquifer are elevated in all planning 

units, and phosphorus, ammonia, and organic nitrogen are particularly elevated in the surfi cial aquifer of the Banana River Planning Unit (Tables 4.1 

and 4.2; Figures 4.1 and 4.2).

Coliform Bacteria

Coliform levels can be difficult to evaluate in ground water samples 

from wells, since biofi lms can form and grow inside the well casing so that 

populations found in wells do not necessarily refl ect those in the aquifer. 

Coliform in wells was evaluated because waterbodies in three planning 

units are impaired for coliform and/or were the cause of beach closures. 

Based on the available data, wells with ground water coming from either 

130 Water Quality Assessment Report: Indian River Lagoon
the surfi cial or Floridan aquifers were not found to have coliform contamination during the period from 2000–06. These data do not suggest a 

signifi cant relationship between bacteria in wells and surface waters.

Evaluations by Planning Unit

This section summarizes, for each planning unit, ground water chemical characteristics that may be related to waterbodies on the draft Verifi ed 

List, evaluates ground water fl ow, reviews pertinent geologic and soil information, and evaluates land use and anthropogenic sources.

Banana River Planning Unit

Three estuarine waterbodies are listed as impaired because of low DO 

(waterbody identifi cation numbers [WBIDs] 3044A, 3057B, and 3057C). 

WBID 3044A is a harbor in the Banana River, and WBID 3057C is a segment of the Banana River. TN was identifi ed as the causative pollutant for 

low DO in all three estuarine waterbodies, with median nitrogen values of 

1.5, 1.5, and 1.6 mg/L, respectively, exceeding the IWR threshold. In the 

surfi cial aquifer, median ammonia and ammonia+organic nitrogen concentrations were 1.7 and 0.65 mg/L, respectively, which were the highest 

values for all planning units in the basin. In addition, orthophosphate and 

phosphorus were highest in the planning unit’s surfi cial aquifer, with medians of 0.82 and 0.72 mg/L, respectively. It is possible that the nutrients in 

ground water and these surface waters have sources in common and that 

ground water discharge provides a nutrient load to these waters.

Ground water discharge to the estuary could be signifi cant. The 

USGS found that the rates of ground water seepage to the IRL were 

 spatially and temporally heterogeneous, ranging from 3 to 100 milliliters 

per meter square per minute (mL m-2 min-1 ) during May (the dry season) 

to 22 to 144 mL m-2 min-1 during August (the rainy season). These data 

implied that the rainfall increased the seepage rates. The study noted 

that the wide range in rates is also likely caused by variation in sediment 

permeability and other geologic characteristics (Swarzenski, Martin, and 

Cable, 2007).

Mosquito Lagoon Planning Unit

The planning unit does not currently contain any waterbodies that 

are listed as impaired. Data from the surfi cial aquifer indicate that ground 

water quality in the planning unit is similar to the North IRL Planning 

Unit, which is discussed below.

North Indian River Lagoon Planning Unit 

Three waterbody segments in the planning unit are listed for DO 

(WBIDs 2963D, 2963F, and 3028); all are classifi ed as estuaries. In 

 addition, two segments, Indian River above NASA Causeway (WBID 

2963E) and Indian River above Brewer (WBID 2963F), are listed for 

nutrients (chlorophyll a). All these segments are classifi ed as estuaries 

of the Indian River, except for Addison Creek (WBID 3028), which is a 

freshwater stream.

Water Quality Assessment Report: Indian River Lagoon 131
TN was identifi ed as the causative pollutant for low DO in the three 

segments (WBIDs 2963D, 2963F, and 3028), with median nitrogen 

values of 1.4, 1.3, and 1.6 mg/L, respectively. The surfi cial aquifer in the 

planning unit could contribute to low DO in some waterbodies. Stream 

basefl ow data obtained in the area suggest that ground water contributes 

approximately half of the total stream fl ow (Tinsley et al., 2007).

Ground water exists as a potential source of nutrients to surface waters. 

Ammonia and ammonia+organic nitrogen levels are lower than the statewide medians for streams, but phosphorus is several times higher in shallow 

ground water than it is in surface waters of the planning unit.

North Central Indian River Lagoon Planning Unit

Four estuarine segments in the planning unit (WBIDs 2963B, 3082, 

3085A, and 3098) are impaired by low DO. The Eau Gallie River 

(WBID 3082) receives drainage from the northern part of the city of 

Melbourne and then fl ows into the northern segment of the Indian River 

(WBID 2963B). Turkey Creek (WBID 3098) is the subject of numerous 

plans for restoration that include muck dredging and the rediversion of 

waters with canals. Crane Creek (WBID 3085A) causative pollutant for 

low DO was identifi ed as BOD, with a median value of 2.6 mg/L.

TN was identifi ed as the causative pollutant for low DO in three estuarine waterways (WBIDs 2963B, 3082, and 3098), with median nitrogen 

values of greater than 1 mg/L for each of them. The surfi cial aquifer in 

the planning unit has a DO median of 1.0 mg/L, and so ground water 

discharge alone could suppress DO if discharge is signifi cant and mixing 

is minimal, such as in a deep stream channel or canal. Ground water is a 

potential contributing source of nutrients to surface waters. 

Ammonia and ammonia+organic nitrogen levels in the planning unit 

are lower than the typical statewide medians for streams, but phosphorus 

is several times higher in shallow ground water than it is in surface waters 

of the planning unit. Basefl ow for the Eau Gallie River was 63 percent 

( Tinsley et al., 2007); thus, if other listed streams are comparable, the 

ground water contribution of nutrients could be a factor in the DO listing.

The Department and SJRWMD designed a ground water Very Intensive Study Area (VISA) near the town of Palm Bay to evaluate the effects 

of suburban development, particularly septic tanks and canals, on water 

 quality in the surfi cial aquifer. The SJRWMD installed 30 monitoring 

wells in the late 1980s and sampled them on several occasions during the 

1990s. Many of the wells were installed between homes and canals or near 

Turkey Creek to intercept ground water fl ow from the neighborhoods to 

the surface waterbodies. Since then, many homes in the VISA have been 

hooked up to the municipal sewer system. It appears from reviewing the 

results of this VISA that sewering of the new communities may be preventing environmental degradation of the surfi cial aquifer system and therefore 

helping to maintain the environmental health of the watershed.

132 Water Quality Assessment Report: Indian River Lagoon
South Central Indian River Lagoon Planning Unit 

The planning unit includes the southern part of the IRL. Submarine 

ground water discharge is believed to occur in this area and can control 

the salinity of the lagoon water. Several waterbodies in the planning unit 

are listed as impaired because of low DO (WBIDs 3128, 3129A, 3129B, 

3135, 3147, 3153, and 3158). In addition, the North Prong Sebastian River 

(WBID 3128) is listed as impaired by iron. 

The surfi cial aquifer in the planning unit has a DO median of 

0.6 mg/L, which is less than typical for the surfi cial aquifer in the basin 

and the SJRWMD. There is a high variation in surface water DO levels, 

suggesting potential ground water discharge under certain conditions and 

in specifi c locations.

The North Canal (WBID 3147) also had phosphorus listed as an 

 additional causative pollutant for low DO. The median phosphorus level 

was 0.25 mg/L in the surfi cial aquifer in the planning unit. This level is 

much higher than the phosphorus in surface waters, and so phosphorus 

contributions by ground water should be a consideration. Estimated basefl ow to the North Prong of the Sebastian River is 66 percent (Tinsley et al., 

2007); thus, ground water discharge should be considered as an input to 

these waters.

While the North Prong Sebastian River (WBID 3128) was listed for 

iron, naturally elevated iron is characteristic of the area. Highly organic 

muck soils occur in the fl oodplains and margins of waterbodies, water 

pH is slightly acidic, and color is high—conditions that frequently point 

toward naturally elevated iron in surface water. Shallow ground water in 

the vicinity is also high in iron. The median iron concentration for the 

surfi cial aquifer in the South Central IRL Planning Unit is greater than 

1,000 mg/L. Elevated iron concentrations in surface water and ground 

water are both related to the organic material that adsorbs, concentrates, 

and releases iron. The release of iron to surface waters could also result 

from the erosion of iron-containing soil from ditch banks and other 

 disturbed areas.

A statistical analysis was conducted to identify the infl uences from 

humic materials and pH on the iron concentrations found in the North 

Prong Sebastian River (Tinsley et al., 2007). Human-induced erosion 

of sediments and other activities in the intensively managed citrus area 

drained by the North Prong Sebastian River could also cause iron to be 

elevated in the river.

Recommendations 

As is the case elsewhere in the state, ground water seepage provides 

water to the streams, canals, and coastal waterbodies of the basin and can 

infl uence surface water quality. Phosphorus, nitrogen, and iron are elevated 

in the surfi cial aquifer and could affect surface water quality to varying 

extents in the basin via ground water infl ows. The following recommendations apply to ground water as a contributing factor to surface waters listed 

as impaired in the IRL Basin:

Water Quality Assessment Report: Indian River Lagoon 133
• Natural sources of phosphorus are present and ground water-related 

phosphorus inputs should be considered in total maximum daily 

loads (TMDLs) developed for DO-listed surface waters in the basin. 

In some instances, ground water may also be a source of nitrogen.

• Both surface and ground waters of the IRL Basin are enriched in 

iron. Natural sources of iron are the major cause of impairment in 

the waterbodies listed for iron, and ground water-delivered iron is 

signifi cant. TMDLs should not be developed for surface waters in 

the basin that are listed for iron unless direct evidence of an anthropogenic source is provided.

• Ground water contributions of low DO may be further evaluated for 

waterbodies that have been listed as potentially impaired because of 

low DO but have no identifi ed causative pollutant.

134 Water Quality Assessment Report: Indian River Lagoon
Chapter 5: The Verified List of Impaired 

Waters

Public Participation

The Florida Department of Environmental Protection (Department) 

worked with a variety of stakeholders to develop and adopt Verifi ed Lists 

of impairments for waters in the six Group 5 basins across the state. The 

waters included on the lists met the listing requirements of the Impaired 

Surface Waters Rule (IWR). 

Drafts of the Verifi ed Lists were made available for public review and 

comment on the Department’s Total Maximum Daily Load (TMDL) 

Program Web site, at http://www.dep.state.fl .us/water/tmdl, and they were 

sent on request to interested parties by postal mail and e-mail. Numerous 

public meetings were held in each basin to encourage public participation 

in the listing process (Table 5.1).

Citizens were given opportunities to comment on the draft lists in 

person, at the public meetings, and in writing. Lists that were revised based 

on received public comments were also made available for further public 

review and comment throughout the full comment period.

Final 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 E 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 D provides additional information. In the IRL Basin, no 

management plans or projects complying with the Department’s guidance 

for reasonable assurance have been provided for the Verifi ed List of 

impaired waters. 

The Verified List of Impaired Waters

Figure 5.1 shows all verifi ed impaired waterbody segments in the IRL 

Basin, for all known causes of impairment, as of September 21, 2007. 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. 

Table 5.3 contains the Verifi ed List of impaired waters for the IRL Basin, 

based on the water quality assessment performed using IWR Run 29. 

Table F.1 in Appendix F contains the Master List of all assessed

Florida’s waterbody classifications are defined 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) 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.

Pollutants Causing Impairments

Table 5.4 summarizes the major parameters for which verifi ed impairments were identifi ed. 

Table 5.4 shows that the greatest number of verifi ed impairments in 

the IRL Basin are for mercury in fi sh. Fish consumption advisories for 

mercury have been issued for all of Florida’s coastal marine waters in all 

basins, including the IRL Basin. To address this problem, one TMDL for 

mercury in fi sh will be developed for the entire state by 2011. 

Dissolved oxygen (DO) and nutrients are the next most prevalent 

impairments in the basin (19 and 14 listings, respectively). DO levels are 

often infl uenced by nutrient levels in surface waters; therefore, DO impairments might be addressed by addressing nutrient impairments in the basin. 

Interim pollutant load reduction goals have been developed for nitrogen, 

phosphorus, and total suspended solids for the IRL lagoon system. Legislation in 1990 removed all domestic wastewater discharges from the lagoon 

and with the inception of the Indian River Lagoon National Estuary 

 Program, numerous stormwater projects have been undertaken in the basin 

to remove nutrient and sediment loads from the lagoon system. 

DO levels, however, are not always associated with a causative pollutant, and low DO levels might be a naturally occurring condition in some 

waters. Where DO does not meet state standards, and the DO impairment 

has been identifi ed as a naturally occurring condition, TMDLs will not be 

developed. 

Metals impairments in the basin (other than mercury in fi sh) (four 

listings) are believed to be associated with surface water/ground water

 interaction in the basin (iron), antifouling paints (copper), and fuels 

(nickel). 

Beach closures (two listings) and fecal coliforms (seven listings) are 

related to bacterial contamination. While not a large problem in the IRL 

Basin, these impairments must be addressed through TMDLs. 

Of the 93 waterbody segments in the IRL Basin, 68 waters are 

impaired for at least 1 parameter. There are a total of 109 parameter 

listings for impairment following the methodology in Appendix E. The 

South Central IRL Planning Unit has the largest number of impaired 

parameter listings with 23, followed by the Banana River Planning Unit 

with 14 listings.

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 (BOD), 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.

Table 5.6 provides the median values for waterbody segments where 

there were a suffi cient number of DO exceedances to place the water on 

the Verifi ed List. Where 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 impairment for that segment is considered a 

potential impairment and it is retained 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

The following waterbodies were listed as impaired based on “other 

information” indicating an imbalance in fl ora or fauna, pursuant to Rule 

62-303.450(2), F.A.C. Based on information provided by the St. Johns 

River Water Management District, the distribution of seagrass in the 

waterbody identifi cation number (WBID) has decreased due to elevated 

nutrients.

Adoption Process for the Verified List of 

Impaired Waters

The Verifi ed 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. 

158 Water Quality Assessment Report: Indian River Lagoon
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 (due to the current insuffi cient 

understanding of how mercury cycles in the environment);

Water Quality Assessment Report: Indian River Lagoon 159
• Canals, urban drainage ditches, and other artifi cial waterbody 

 segments that are listed only due to exceedances of dissolved oxygen 

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 priority waters for TMDL development in the 

Indian River Lagoon (IRL) Basin. There are 21 waters listed in the table 

that are high priorities on the 1998 303(d) list. 

Total Maximum Daily Load Development

TMDLs for point and nonpoint source pollutants will be developed for 

impaired waterbodies during Phase 3 of the Watershed Management Cycle, 

and the TMDLs will be adopted by rule at the end of the phase. 

TMDL development involves determining the maximum amount of 

a given pollutant a waterbody can assimilate and still meet the applicable 

numeric or narrative state 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 (worst-case temperature and ambient fl ow conditions, and an 

assumption that all permitted point sources discharge at the maximum 

permitted quantity).

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 water fl ow. 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.

Water Quality Assessment Report: Indian River Lagoon 177
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 

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 IRL 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;

178 Water Quality Assessment Report: Indian River Lagoon
• 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.

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) 
190 Water Quality Assessment Report: Indian River Lagoon 

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 Florida Legislature by February 2001 addressing the allocation 

process. 
Water Quality Assessment Report: Indian River Lagoon 191

• Authorizes the Department to develop basin plans to implement TMDLs, coordinating with the 

water management districts, the Florida Department of Agriculture and Consumer Services 

(FDACS), 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 FDACS 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 Florida 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. 
192 Water Quality Assessment Report: Indian River Lagoon 

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 

reduce the amount of pollutants that cause impairments must also be produced and 

implemented. 
Water Quality Assessment Report: Indian River Lagoon 193

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. 
194 Water Quality Assessment Report: Indian River Lagoon 

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: Indian River Lagoon 195

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. 

Table A.3: Potentially Affected Stakeholders and Actions to Achieve TMDLs 

Potentially Affected Stakeholders Actions To Achieve TMDL 

Municipal stormwater/wastewater programs Reduce and treat urban stormwater runoff through 

stormwater retrofits, replacement of septic tanks 

Commercial developers, homebuilders, individual 

homeowners 

Improve development design and construction, 

enhance BMPs, replace septic tanks 

Municipal and industrial wastewater treatment 

facilities, National Pollutant Discharge Elimination 

System (NPDES) permitted facilities

discharges 

Farming and silviculture operations Reduce and treat runoff through BMPs 

Federal, regional, state agencies; regional and 

local water quality coalitions Carry out waterbody restoration projects 

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.” 
198 Water Quality Assessment Report: Indian River Lagoon 

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 (SJRWMD) 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. (See Noteworthy 

for a definition of riparian). 

BEST MANAGEMENT PRACTICES

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: Indian River Lagoon 199

NOTEWORTHY: DEFINITION OF RIPARIAN 

Riparian: Of, on, or relating to the banks of a natural course of water.

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 Florida 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. 

Once FDACS 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

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 Florida Legislature prior to its adoption. The Department will also 

continue to work with local stakeholders on TMDL allocation issues and implementation 

plans.

Table B.1: Types of Natural Communities 

Community Type Description of Community Acre

Coastal Strand 

Coastal strand community occurs on well-drained sandy soils and typically includes the zoned 

vegetation of the upper beach, dunes, or coastal rock formations. Community forms along 

high energy shorelines and is strongly affected by wind, waves, and salt spray. Vegetation typically consists of low growing vines, grasses, herbaceous plants, and small trees or shrubs. Common plants are morning glory, Spanish bayonet, sea oats, saw palmetto, wax myrtle, and sea grape. 

1844.7

Sand/beach Barren land with little or no vegetation. Areas constantly affected by waves and tidal actions and dune sands or other bare areas of sand. 2906.9Xeric oak scrub 

A xeric hardwood community composed of clumped patches of low growing oaks interspersed with bare areas of sand. Community type occurs on deep, well-washed, sterile sands, and is also found as the understory in sand pine scrub communities. Dominant plant species are Chapman’s oak, myrtle oak, sand-live oak, scrub holly, scrub plum, scrub hickory, rosemary, and saw palmetto. 

9583.8

sand pine scrub 

Sand pine scrub is found on extremely well drained, sorted, sterile sands deposited along 

ancient shorelines and islands of ancient seas. Overstory is dominated by sand pine with a woody understory of myrtle oak, Chapman’s oak, sand-live oak, and scrub holly. This community is found almost exclusively within Florida. Fire is an important factor in the maintenance and survival of this type of community. 

2860.8

sandhill 

These communities are found in areas of rolling terrain on deep, well drained, white to yellow, 

sterile sands. Community is dominated by an overstory of long leaf pine and an understory of turkey oak and bluejack oak. A diverse assemblage of herbaceous plants comprise the ground cover. Fire is an important factor in controlling the community. 

1.11 

dry prairies 

These are large native grass and shrublands occurring on flat terrain interspersed with scattered cypress domes and strands, bayheads, isolated freshwater marshes, and hardwood hammocks. Palmetto prairies, where the overstory trees have been thinned or eliminated area also included in this category. Common species are grasses, sedges, herbs and shrubs, saw palmetto, gallberry, blueberry, wiregrass, and various bluestems. 

140485

mixed hardwood-pine forest 

Upland forest that contain a mixture of conifers and hardwoods as co-dominant overstory components. This community may include longleaf pine, slash pine, and loblolly pine in association with live oak, laurel oak, water oak and other hardwood species. 

30209
202 Water Quality Assessment Report: Indian River Lagoon 

Community Type Description of Community Acre

hardwood hammock and forests 

Major upland hardwood associations occurring on fairly rich sandy soils. Species composition and local distributions are due in part to differences in soil moisture regimes, soil type, and 

location within the state. Both mesic and xeric hammocks exist. Mesic hammocks are characterized by laurel oak, hop hornbeam, blue beech, sweetgum, cabbage palm, American 

holly, and southern magnolia. Xeric hammocks occur on deep, well-drained soils where fire has been absent for long periods of time. Common xeric hammock species are live oak, sand-live oak, and pignut hickory. 

34032

pinelands 

This category includes both pine flatwoods and pine plantations. Pine flatwood occur on flat sandy terrain where the overstory is characterized by longleaf pine, slash pine, or pond pine depending on soil moisture and drainage at a given location. Scrubby flatwoods is another pineland type that is found on drier ridges and on or near old coastal dunes. 

139169

freshwater marsh and wet prairie 

Wetland communities dominated by herbaceous plants growing on a variety of substrates in 

areas of variable water depth and inundation regimes. Generally, freshwater marshes occur 

in deeper water with more regular inundation and are characterized by tall emergent and floating-leaved species. Freshwater marshes can occur within flatwood depressions, along lakes and river shorelines, and as open areas within hardwood and cypress swamps. Wet prairies commonly occur as scattered, shallow depressions within dry prairies. Combinations of pickerel weed, sawgrass, maidencane, arrowhead, fire flag, cattail, spike rush, bulrush, 

water lily, water shield, and various sedges dominate freshwater marshes and wet prairies. 

168207

shrub swamp 

Shrub swamps are wetland communities dominated by dense, low-growing, woody shrubs or small trees. They are usually characteristic of wetland areas that are experiencing environmental change and are early to mid-successional in species composition and structure. Common species include willow, wax myrtle, primrose willow, buttonbush, and 

saplings of red maple, sweetbay, and other hydric trees. 

96653

bay swamp 

Hardwood swamps contain broadleaf alternate leafed evergreen trees that grow in shallow, stagnant drainages or depressions. Overstory trees are dominated by sweetbay, swamp bay, 

and loblolly bay. 

2005.7

cypress swamp 

These communities are strongly dominated by either bald cypress or pond cypress. They occur as forested borders along streams and lakes, or in depressions as circular domes or linear strands. 

39103

cypress/pine/cabbage palm Community include cypress, pine, and cabbage palm, but none of the species obtains dominance. This assemblage forms a transition between moist upland and hydric sites. 130.99 mixed wetland forest This is a mixed wetland forest community in which neither hardwoods nor conifers achieve dominance. 43347
Water Quality Assessment Report: Indian Riv

Community Type Description of Community Acre

hardwood swamp 

Wooded wetland communities composed of either pure stands of hardwoods or occur as a mixture of hardwood and cypress where hardwoods achieve dominance. Occur on organic soils and form the forested floodplain of non-alluvial rivers, creeks and broad lake basins. Tree species include black gum, water tupelo, bald cypress, dahoon holly, red maple, swamp ash, sweetbay, and cabbage palm. 

59021

hydric hammock 

Hydric hammocks occur on poorly drained soils or soils with high water tables. These are still 

water wetlands that flood less frequently and for shorter time periods than mixed hardwood and cypress swamps. Typical tree species are laurel oak, live oak, cabbage palm, southern red oak, and sweetgum. Ground cover may or may not be present. Common community found along the St. Johns River. 

2455.2

saltmarsh 

Herbaceous and shrubby wetland community found in low energy estuarine shorelines. Saltmarshes can be found interspersed within mangrove communities or as transition zones between freshwater marshes and mangroves. Plant composition and distribution is largely 

dependent on the degree of tidal inundation. 

23445

mangrove swamp Dense brackish swamps that occur along low-energy shorelines and in protected, tidally influenced bays of southern Florida. 14953open water Freshwater lakes and streams and estuarine and coastal marine waters. 54599shrub and brushland

Appendix D: 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: 

1. 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 

2. 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 U.S. 

Environmental Protection Agency (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 Florida Department of Environmental Protection's (Department) 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. 
Water Quality Assessment Report: Indian River Lagoon 221

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 

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 

1. 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. 

2. 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 the 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 
222 Water Quality Assessment Report: Indian River Lagoon 

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. 

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.

 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. 
Water Quality Assessment Report: Indian River Lagoon 223

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. 

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: 

1. 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 NED 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. 

2. 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. 
224 Water Quality Assessment Report: Indian River Lagoon 

3. 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 

the date by which designated uses will be restored), and any enforcement 

programs or local ordinances, if the management strategy is not voluntary. 

4. 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. 

5. 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 

 

2

 Baseline data would be data for the year prior to designation of the OFW. 
Water Quality Assessment Report: Indian River Lagoon 225

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. 

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 
226 Water Quality Assessment Report: Indian River Lagoon 

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 

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 E: 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 and Human Services (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 
230 Water Quality Assessment Report: Indian River Lagoon 

volunteer monitoring group. Several of these databases are readily available to the public 

via the Internet. 

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 E.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.

Note: Typically, a 10-year data record is used for the development of the Planning Lists, and a 7.5-

year record is used for the Verified Lists. 

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: Indian River Lagoon 231

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 bacteria, 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 E.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 water 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 

greater than or equal to 10 percent. To be placed on the Verified List, at least a 90 

percent confidence rate was required. 
232 Water Quality Assessment Report: Indian River Lagoon 

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, 

bioassessment methods involve the identification of a biological reference condition, 

based on data from unimpaired or least impacted waters in a given region. 
Water Quality Assessment Report: Indian River Lagoon 233

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 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. (see Noteworthy for a definition of riparian). 

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. 

NOTEWORTHY: DEFINITION OF RIPARIAN 

Riparian: Of, on, or relating to the banks of a natural course of water. 
234 Water Quality Assessment Report: Indian River Lagoon 

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 

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. 
Water Quality Assessment Report: Indian River Lagoon 235

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. 

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. 
236 Water Quality Assessment Report: Indian River Lagoon 

Appendix F: Master List for the Indian River Lagoon Basin 

Table F.1 contains the listing status of all assessed waters in the basin. It should be 

noted that subsequent to the update of the 303(d) list, some waterbody segments were 

further subdivided to produce separate segments for lakes versus their surrounding 

watersheds. Therefore, Table F.1 shows the waterbody identification numbers (WBIDs) 

under which these segments were designated in the 1998 303(d) list, as well as the new or 

currently recognized WBIDs for them. 

Information in this appendix was obtained from an inventory of the Legacy and 

Modernized STORET Databases, as well as data contributed directly to the Florida 

Department of Environmental Protection (Department) by individual data providers. 

Table F.2 includes only stations with data from the Planning and Verified assessment 

periods.
