City of Ocoee - Director of Public Works PREPARED BY: Johan Rodriguez CHECKED BY: David Hamstra, P.E. ~~ DA TE: December 28, 2005 RE: Determination of the Trophic State Index for Selected Lakes within the City of Ocoee (July 1992 - December 2004) 1.1 Introduction The City of Ocoee, as part of the University of Florida's LAKEWATCH program, has accumulated lake water quality data for a period of record from July of 1992 through December 2004, for twelve (12) lakes within the City of Ocoee. In particular, the LAKEW A TCH program coordinates the sampling and consolidation of Total Nitrogen, Total Phosphorus, Chlorophyll-a, and Secchi Depth data. The results are then processed to yield the Trophic State Index (TSI) for each lake; the accumulation of all data obtained within a given calendar year are then published in an annual report made available via the LAKEW A TCH website (http://lakewatch.ifas.ufl.edu/). TSI values range from 0 to 100, with 0 being the best possible water quality and 100 being the worst. A more detailed description of TSI can be found in Appendix A of this memorandum along with the empirical equations utilized to calculate TSI, as provided within a document entitled 1994 Lake Water Qualitv Reoortfor the City of Orlando. The Florida Department of Environmental Protection (FDEP), as part of the Total Maximum Daily Load (TMDL) program, has classified any water body with a TSI greater than or equal to 60 to be Impaired for Nutrients (TSI). The City of Ocoee currently has four (4) lakes designated as impaired according to the Orange County section of the Group 2 - Middle St. Johns River Basin Verified List (Adopted via Secretarial Order on May 27,2004): Lake Lotta, Lake Prima Vista, Starke Lake, and Prairie Lake. Please note that PBS&J, acting as a consultant to Orange County, attempted to have Lake Lotta, Prairie Lake, and Starke Lake removed from the "draft" list of impaired water bodies by presenting scientific evidence that showed that these water bodies possessed an average annual TSI of less than 60. This effort was unsuccessful and all four impaired water bodies contained in the "draft" verified list remained in the adopted verified list. PEC / Professional Engineering Consultants, Inc. December 28, 2005 Page 2 of 6 The four water bodies on the adopted verified list are all considered "Medium-Priority Waters". As such, they are on the second five (5) year rotation within Group 2 and are scheduled for TMDL Development in 2008. After the TMDLs are developed, FDEP will begin working with all stakeholders (City of Ocoee, SJRWMD, FOOT, selected homeowners and/or homeowners associations, etc.) to begin developing a Basin Management Action Plan (B-MAP) to achieve the specified TMDLs. Once the B-MAP is developed, it must then be implemented while continuing to monitor the water bodies. For a further explanation of the TMDL program, refer to the documents contained within Appendix B of this memorandum. 1.2 Summary of Lake Water Quality Figure 1 on page 4 summarizes the calculated Florida Trophic State Index (TSI) for each respective lake, as well as the classification of the lake water quality in terms of both the City of Orlando and Florida Department of Environmental Protection (FDEP) nomenclature. As shown in Figure 1, Spring Lake has the best average water quality over the course of the study to date, while Lake Prima Vista has the worst. Table 1 on the following page contains a summary of the average annual TSI values for all lakes over the course of the study period (refer to Appendix C of this memorandum for all numerical LAKEWATCH data).

For further discussion on the methodology of the trend analysis, please refer to Appendix A of this memorandum. Table 2 below depicts the TSI trend for each of the lakes. As shown, the water quality is improving in Lake Moxie, Lake Johio, and Lake Stanley. In contrast, Prairie Lake shows a degrading water quality trend. All other lakes show no significant trend. Please note that Prairie Lake only shows a degrading water quality trend as a result of the abnormal spike in TSI that occurred in 2001.

December 28, 2005 Page 6 of 6 1.4 Conclusion Overall, the selected lakes within this study are all in good to fair condition. Three (3) lakes show an improving trend, which include Lake Moxie, Lake Johio, and Lake Stanley. However, Prairie Lake shows a degrading trend and this is cause for concern. In this case (Prairie Lake), data has not been collected for over three (3) years. The City of Ocoee must implement a more rigorous sampling program (including lake stage recording) in order to better quantify the conditions and trends of all its lakes, especially those with poor or degrading water quality. This will enable a more efficient development of the Basin Management Action Plan for meeting the TMDLs of the City's impaired water bodies. 1.5 References 1. 1994 Lake Water Quality Reoort, Stormwater Utility Bureau - Public Works Department, City of Orlando, Florida, May 1995. 2.

APPENDIX A DESCRIPTION OF FLORIDA TROPHIC STATE INDEX PEC I Professional Engineering Consultants, Inc. December 28, 2005 Appendix A A-1 Florida Trophic State Index The following excerpt was obtained from a document entitled 1994 Lake Water Quality Report for the City of Orlando, and provides a detailed discussion of the Florida Trophic Index relative to the classification of lake water quality. "The water quality of Florida lakes is commonly assessed by determining the trophic state of the lake. The trophic state is a measure of the degree of productivity in the water column. Eutrophication is the process in which a lake becomes nutrient enriched which in turn alters the chemical, physical and biological characteristics of the lake. Most of the changes in the lakes characteristics result from increased plant production which is in turn caused by increased levels of nutrients. Since most water quality problems associated with Florida lakes can be attributed to eutrophication and eutrophic lakes have a high potential for water quality problems, trophic state measurements are used by the City as the primary indicator to detect changes over time and to rank lakes by water quality. The City uses the Florida Trophic State Index (Brezonik 1984) which was derived using data from 313 Florida lakes. The trophic state of a lake is determined by measuring key water quality parameters and entering these values into an empirical formula which calculates a numeric value. The parameters used to determine the trophic state of a lake are total nitrogen, total phosphorus, chlorophyll-a (measures planktonic algae densities) and secchi depth (measures water transparency). These parameters are all closely correlated and the index allows for a better measure of overall trophic state than using individual indicators. The index calculates a number that can be assigned a particular trophic state. A lake which has low nutrient concentrations in the water column will typically have very high water transparency because the algae densities are low. These lakes are termed oligotrophic and are generally considered as lakes with excellent water quality. Oligotrophic lakes tend to be deep with abundant oxygen and a low build-up of organic material on the bottom. lakes were assigned an oligotrophic status if trophic state index values were less than 50. PEC / Professional Engineering Consultants, Inc. December 28, 2005 Appendix A As nutrient concentrations increase in a lake, the algae densities increase and water transparencies decrease. A lake with high levels of nutrients and planktonic algae is termed eutrophic. A eutrophic lake is highly productive and will have the potential for water quality problems resulting from severe algae blooms which can deplete oxygen and form mucky organic layers on the lake bottom. lakes were assigned a eutrophic status if trophic state index values were between 61 and 70. lakes with moderate nutrient levels, and water quality characteristics between oligotrophic and eutrophic conditions are termed mesotrophic. Mesotrophic lakes will typically only have occasional water quality problems and are generally considered to have good water quality. lakes were assigned a mesotrophic status if the trophic state index values were between 50 and 60. lakes which have reached advanced stages of the eutrophication process are termed hypereutrophic. These lakes are characterized by persistent algae blooms, extreme fluctuations in dissolved oxygen, and deep organic muck layers. Hypereutrophic lakes in the City tend to be shallow and have mucky sediments from organic material which is produced in the lake faster than it can be removed by decomposition processes. Hypereutrophic conditions are indicated by trophic index values greater than or equal to 71. The Florida Department of Environmental Protection uses trophic state index values to assess a good, fair or poor rating to Florida lakes. Trophic state index values between 0 and 59 correspond to good water quality, 60 to 69 is fair, and values greater than 70 indicate poor water quality (Hand et ai, 1990). While the process of a lake going from an oligotrophic to a eutrophic state is a natural occurrence, human impact on lake drainage basins can greatly accelerate this process. When the eutrophication process is accelerated due to unnatural causes, such as urbanization, the process is termed cultural eutrophication. Since most water quality problems in Florida lakes can be attributed to cultural eutrophication, the majority of pollution abatement and lake restoration methods attempt to reverse this process through nutrient removal or inactivation. PEC / Professional Engineering Consultants, Inc. December 28, 2005 Appendix A The fact that a lake is eutrophic does not necessarily mean the condition is man-made or undesirable. Many Florida lakes are eutrophic because of naturally occurring high nutrient concentrations in the soils of the watershed. Water quality can be a matter of individual perspective and depend on primary uses for the lake. For example, an oligotrophic lake would be desirable to individuals who swim or ski while a eutrophic lake is more productive and will tend to support larger populations of fish and wildlife for anglers and bird watchers. One factor that the Florida Trophic State Index does not use in determining the trophic state of a lake is the biomass of aquatic macrophytes (vascular plants and large non-planktonic algae). This is a missing feature since the trophic state of a lake is meant to express overall productivity, and aquatic macrophytes can comprise a substantial amount of the productivity in a lake. Lakes which have large densities of aquatic macrophytes may have excellent water quality but may not be truly oligotrophic because they have high productivity in the form of macrophytes instead of algae. For this reason the trophic state index values should only be used as an indicator of water quality not the overall trophic condition in lakes which have abundant aquatic macrophytes. Aquatic macrophytes are generally considered desirable because they improve wildlife habitat and can have a positive effect on water quality. Macrophytes are considered undesirable when densities reach excessive levels which interfere with lake uses. Aquatic macrophytes, especially exotics such as hydrilla and water hyacinths, have the potential to cause severe water quality problems such as low dissolved oxygen and high organic loading if the densities are not monitored and controlled." A-2 Water Quality Trend Analysis - Methodology In order to determine if the water quality within a particular lake is changing over time, the TSI values for each lake were plotted versus their sampling date. A linear regression analysis using the least-squares method was performed on the data points. This analysis generated a linear trend which represents the relationship of TSI and time. This linear trend is presented as a straight line described by an equation of the form y = mx + b. In this equation, m represents the slope of the line; a positive slope indicates that the TSI is rising over time (i.e. the water quality is degrading) and a negative slope indicates that the TSI is decreasing with time (i.e. the water quality is improving). PEC / Professional Engineering Consultants, Inc. December 28, 2005 Appendix A Another important result of the linear regression analysis is the R2 value. Simply stated, the R2 value is an indicator of the strength of the relationship between the variables and the trend. For example, an R2 value of 0.3 indicates that 30% of the change in the TSI can be associated with time; the remaining 70% is associated with other factors as well as random fluctuations. In the case of surface water trends in the State of Florida, R2 values in excess of 0.20 are considered significant (Swithart e1. al. 1984). Trend determinations for lakes in the City of Ocoee were found by assigning each lake a status of improving, no trend, or degrading, depending on the line slope and R2 value for each regression analysis of trophic state versus time. Improving trends were assigned to lakes with R2 values of > 0.20 and decreasing trophic states. No trend was assigned if the R2value was <0.20. A degrading trend was assigned for increasing trophic states and R2 values> 0.20. PEC / Professional Engineering Consultants, Inc.

APPENDIX B TMOL Program Overview PEC I Professional Engineering Consultants, Inc. 1_ I M8XI... D811 8 I Guidance For Local Officials Are You Ready? Cooperatively produced by Florida Stormwater Association Florida Department of Environmental Protection What is the TMDL Program'? The Total Maximum Daily Load (TMDL) Program is a federally required water quality program administered by the Florida Department of Environmental Protection (DEP) under the Florida Watershed Restoration Act (Section 403.067, Florida Statutes). Through the program, DEP works closely with affected stakeholders to determine how to reduce targeted pollutant loadings to restore the legally designated uses (e.g., drinking water, fishing, swimming, shellfish harvesting) of the polluted waters. What are TMDLs'? A TMDL is the maximum amount ofa pollutant that a waterbody can receive and maintain its designated uses. A given waterbody may have several TMDLs - one for each targeted pollutant (phosphorus, coliforms, nutrients, etc.). Under the Florida Watershed Restora- tion Act, TMDLs must be developed for all waters that do not meet their desig- nated uses due to human impacts and, consequently, are defined as "impaired." The primary sources of these human- induced impairments are pollutants in urban stormwater, agricultural runoff, and permitted industrial and municipal wastewater treatment plants. A TMDL, or a waterbody's assimilative capacity, is scientifically derived, typically using existing monitoring data and water quality models or empirical relationships between the pollutant load and the waterbody's response. The final TMDL provides a margin of safety that accounts for uncertainty in the analysis. What distinguishes the TMDL Program from other state water quality programs'? The issues that the TMDL Program addresses are not new. Nonpoint sources, such as stormwater and agricultural runoff, and point sources, such as industrial wastewater outfalls, have created water quality concerns in Florida for decades and have been addressed in various ways. However, the TMDL Program does bring something new to existing local, regional, and state water quality protection efforts by establishing water quality targets, or actual pollutant load limits, that indicate how much of a pollutant a lake, river, stream, or estuary can absorb and maintain its designated use. Before establishing these targets, DEP identifies the location, nature, and degree of impairments; the pollutants of concern; and, as much as possible, the pollutant sources. In implementing the TMDL Program, DEP is taking an open, broad-based approach to local stakeholder involve- ment, a watershed management approach. The intent is to build on and strengthen local efforts to protect and restore water quality. The TMDL Program will add emphasis to stormwater management. What are the federal and state laws governingTMDLs'? Section 303 (d) of the Clean Water Act (33 United States Code) requires states to identify impaired waters and the pollutants causing the water quality impairment. The state must then establish a TMDL for each identified pollutant. Though these federal requirements were enacted in the early 1970's, they were not implemented in most states until citizen and environmental groups filed a number of successful lawsuits in the mid-1990's. In Florida, DEP prepared a planning list in 1998 of potentially impaired waters (the 1998 303(d) list) and submitted the list to the U.S. Environmental Protection Agency (EPA). In 1999, the settlement of a lawsuit in Florida against the EPA by Earth]ustice resulted in a consent decree that established a thirteen-year sched- ule for EPA to complete TMDLs for certain waters on Florida's planning list. Later in 1999, the Florida Legislature passed the Florida Watershed Restora- tion Act, establishing the framework and requirements for implementing a state TMDL Program. The Act directed DEP to adopt by rule (the "Impaired Surface Waters Rule") a scientific methodology to determine whether a waterbody is indeed "impaired," and required DEP to adoptTMDLs by rule. How and when are TMDLs established? Phase 1: Preliminary Evaluation of Water Quality TMDLs are developed, allocated and implemented through a watershed management approach (managing water resources within their natural boundaries) that addresses the state's 52 major hydrologic basins in five groups.

I There are a number ofTMDLs that EPA will be proposing in Florida in order to satisfy the consent decree with Earth]ustice. The legal status of EPA- generated TMDLs is not yet clear, as neither the Florida Watershed Restora- tion Act nor the consent decree address their implementation. I I How are TMDLs implemented? I Two key steps in implementingTMDLs in a basin are: I 1. Allocating detailed pollutant load reductions, based on the initial alloca- tions in the TMDL. To reduce pollutant loadings to achieve a TMDL, each point and nonpoint source discharging a pollutant of concern must be reduced in an equitable manner. TMDLs include an "initial allocation" of pollutant load reductions between point and nonpoint sources. In most cases, this initial allocation will need to be broken down into more detail, to assign responsibility for specific reductions. Future growth must be considered in the allocation process. I I I I 2. Developing a basin management action plan (B-MAP) that reflects the detailed allocations and contains short- term and long-term projects and activities to achieve the applicable TMDLs in the basin, along with a strategy for monitoring, follow-up, and I I 8id"'~:; t::I Co.." lia.c'. ~ D "'''_.1' fZJ c.n..c.. lID <>-0.._ - C(1\.WJI P w...&W'y c.",",'~ plan revision. Implementing corrective actions and achievingTMDLs may take many years. During Phases 3 and 4 of the watershed management cycle, DEP and basin stakeholders will jointly develop strategies to implement the reductions assigned in the allocation process. These will be expressed in the B-MAP. The development of the B-MAP is an opportunity for affected stakeholders to cooperate, coordinate, and negotiate on the best and most cost-effective ways to achieve a TMDL. A wide variety of approaches may be used. " !QtIJt...., An important element of a B-MAP will be the identification of funds and potential funding mechanisms to achieve load reductions. State and federal funds may be available to finance some projects and activities. Many of the management actions addressed in the B-MAP may come from existing plans and projects. The load reductions reasonably expected from these existing or planned efforts may be credited toward the reductions needed to meet the applicable TMDL. Stake- holders will then identify additional projects and activities to complete the needed reductions. In some basins, a B- MAP may incorporate or be incorpo- rated into an existing watershed management plan. The costs to reduce pollutant loadings are expected to be high. The biggest fiscal impacts involve large retrofit programs within urbanized areas What are the implications of the TMDL Program for local governments? Costs. The greatest impact to local govern- ments likely will stem from the sizable costs of implementing projects and activities to achieve TMDLs. Stormwater regulations to this point have largely addressed future develop- ment. Reducing pollutant loadings to meet TMDLs may require retrofitting stormwater and wastewater systems. According to several studies, fiscal impacts on many city and county governments will generally range from $7,500 to more than $12,000 per acre to build stormwater treatment facilities to retrofit urbanized areas. The Florida Stormwater Association estimates that the cumulative retrofit costs would be between $1 billion and $5 billion, and probably much higher, if local governments were to achieve the current standards for future develop- ment in 90 percent of urban areas in Florida. These estimates do not consider the need to address discharges from wastewater treatment plants, septic tank systems, or agricultural lands. Benefits. In addition to improving water quality, the TMDL Program will: . Produce better monitoring and more effective use of existing and new water quality information. . Provide restoration targets and help define responsibility for management actions. · Build on and strengthen existing restoration efforts of local govern- ments, water management districts, established coalitions, DEp, and others. . Focus funding and other resources on priority water resource problems. . Trigger improvements in stormwater management by local governments, industry, agriculture, private develop- ments, businesses, and others. · Stimulate new approaches to land use design and development that mini- mize associated water resource problems. · Help establish better working relation- ships among citizens and public and private organizations that deal with water quality issues. How and when do I get involved? TMDLs and watershed restoration are part of state and federal water policy. They will significantly affect local government budgets and the ways in which water quality programs operate in Florida. Although Florida is ahead of the stormwater management game com- pared to most other states, achieving TMDLs will be an expensive endeavor. City and county officials need to develop local strategies to address TMDLs. To participate in the TMDL Program successfully, local officials should take the following steps, in partnership with other stakeholders and DEP: 1. Engage Learn the status of the waterbodies in your jurisdiction (Le., are they poten- tially impaired, verified as impaired, or not classified either way?) and where they fall in the basin rotation schedule. Have your staff coordinate with DEP technical staff to ensure that your local water quality data is considered in assessing whether waters in your area are impaired. Review and comment on planning lists and draft verified lists of potentially impaired waters and draft TMDLs for waters in your basin. 2. Initiate and Participate Your leadership will ensure that the TMDL Program addresses local issues and concerns. Work with DEP to determine how stakeholders in your community can be involved most effectively in the TMDL Program and to create a stakeholder group. Educate stakeholders in your communi- ties about TMDLs and how they might be addressed. Make them aware of opportunities to provide input during the development ofTMDLs, allocations, and basin management action plans. Establish working committees of community leaders and interest groups so that their input can be obtained throughout the five-phase process. 3. Document Activities Work with DEP to compile information on the water quality improvement ~., ~' The basinwide approach will encourage partnerships between stakeholders to achieve water quality goals. I I I I I ~ a I I I I I I I I I I I I projects and activities your jurisdiction has underway or are planned that may help achieve TMDLs. This information will be used in determining what load reductions can be expected from current efforts and what further reductions are needed. 4. Assess Options Evaluate your community's options for further improving water quality. Through the development of the B-MAp, stakeholders will help each other determine cost-effective ways to achieve TMDLs. 5. Develop Financing Alternatives Begin to think about long-term strate- gies for financingTMDL costs. What are appropriate sources of revenue to fund TMDLs? Have you established a stormwater utility? ''''~.J. ./ ~r-"-- -.~ ,-~ ~ '> Communities with active stormwater management and water quality monitoring programs in place are better positioned to deal with the TMDL requirements. I When? NOW! I Early involvement will give local government a strong voice in determin- ing the pollutant load reduction strate- gies proposed in Basin Management Action Plans, ensuring consideration of local goals and constraints. I I If you are already part of a TMDL stakeholder process in your basin, you may still have questions or need additional assistance. If you are not aware of any stakeholder activities, you can check with DEP to see what the status of the TMDL process is in your basin. I I I I I I I I I I I I I I How are stakeholders being involved? DEP's approach to stakeholder involve- ment is to work through existing forums and processes where practicable, and initiate new processes where necessary, to build consensus on how TMDLs should be achieved. Stakeholders have a crucial role in determining detailed pollutant load reduction allocations and developing and implementing B-MAPs. Ideally, the TMDL implementation process will be driven at the locallevel, with DEP's involvement and guidance. In step with the basin rotation schedule, DEP is building on or initiating stake- holder processes around the state in areas such as the Lower St Johns River Basin, the Upper Ocklawaha River Basin, the Orange Creek Basin, the Tampa Bay Basin and its tributaries, the St Lucie- Loxahatchee River Basin, the Ochlockonee-St Marks River Basin and others. The approach to stakeholder involvement in each basin is based on the characteristics and needs of the area. The approach to stakeholder involvement in each basin is based on the characteristics and needs of the area. Stakeholders have a critical role in determining the polllltant load reduction allocations within their basin.
