Osceola County Lakes Management Plan 2015 Osceola County Lakes Management Plan ADOPTED Osceola County BoCC September 14, 2015 Osceola County Lakes Management Plan Prepared by: Community Development Department Community Resources Office September 2015 The Mission of Osceola County’s Lakes Management Program is to protect, enhance, conserve, restore, and manage the County’s aquatic resources. We accomplish this through education, coordination with other agencies, and maintenance and management of lake systems. Activities include hydrologic management, habitat preservation and enhancement, aquatic plant management, water quality improvement, and provision of recreational opportunities. Our goal is to improve, enhance and sustain lake ecosystem health, while avoiding impacts to downstream systems, for the benefit of the fish and wildlife resources and the residents of, and visitors to, Osceola County.

INDEX OF SURFACE-WATER RECORDS TO SEPTEMBER 30,1955 PAET 2. SOUTH ATLANTIC SLOPE AND EASTERN GULF OF MEXICO BASINS By P. R Speer and A. B. Goodwin EXPLANATION This index lists the streamflow and reservoir stations in the South Atlantic slope and Eastern Gulf of Mexico basins for which records have been or are to be published in reports of the Geological Survey for periods prior to September 30, 1955. Periods of record for the same station published by other agencies are listed only when they contain more detailed information or are for periods not reported in publications of the Geological Survey. The stations are listed in the downstream order first adopted for use in the 1951 series of water-supply papers on surface-water supply of the United States. Starting at the headwater of each stream all stations are listed in a downstream direction. Tributary streams are indicated by indention and are inserted between main-stem stations in the order in which they enter the main stream. To indicate the rank of any tributary on which a record is available and the stream to which it is immediately tributary, each indention in the listing of stations represents one rank.

  • Blue-Green Algal Bloom Weekly Update Reporting March 26 - April 1, 2021
    BLUE-GREEN ALGAL BLOOM WEEKLY UPDATE REPORTING MARCH 26 - APRIL 1, 2021 SUMMARY There were 12 reported site visits in the past seven days (3/26 – 4/1), with 12 samples collected. Algal bloom conditions were observed by the samplers at seven of the sites. The satellite imagery for Lake Okeechobee and the Caloosahatchee and St. Lucie estuaries from 3/30 showed low bloom potential on visible portions of Lake Okeechobee or either estuary. The best available satellite imagery for the St. Johns River from 3/26 showed no bloom potential on Lake George or visible portions of the St. Johns River; however, satellite imagery from 3/26 was heavily obscured by cloud cover. Please keep in mind that bloom potential is subject to change due to rapidly changing environmental conditions or satellite inconsistencies (i.e., wind, rain, temperature or stage). On 3/29, South Florida Water Management District staff collected a sample from the C43 Canal – S77 (Upstream). The sample was dominated by Microcystis aeruginosa and had a trace level [0.42 parts per billion (ppb)] of microcystins detected. On 3/29, Florida Department of Environmental Protection (DEP) staff collected a sample from Lake Okeechobee – S308 (Lakeside) and at the C44 Canal – S80. The Lake Okeechobee – S308 (Lakeside) sample was dominated by Microcystis aeruginosa and had a trace level (0.79 ppb) of microcystins detected. The C44 Canal – S80 sample had no dominant algal taxon and had a trace level (0.34 ppb) of microcystins detected. On 3/29, Highlands County staff collected a sample from Huckleberry Lake – Canal Entrance.

  • Chapter 8C: St. Lucie and Caloosahatchee River Watersheds Annual Report
    2019 South Florida Environmental Report – Volume I Chapter 8C Chapter 8C: St. Lucie and Caloosahatchee River Watersheds Annual Report Cassondra Armstrong, Fawen Zheng, Anna Wachnicka, Amanda Khan, Zhiqiang Chen, and Lucia Baldwin SUMMARY A description of the estuaries and the river watersheds is followed by a summary of the conditions of the hydrology (rainfall and flow), water quality (salinity, phosphorus, nitrogen, and chlorophyll a [Chla]), and aquatic habitat (oysters and submerged aquatic vegetation [SAV]) based on results of the Research and Water Quality Monitoring Programs (RWQMPs). Following the summary for each estuary, significant findings during the Water Year 2018 (WY2018; May 1, 2017–April 30, 2018) reporting period are highlighted. In addition, the St. Lucie and Caloosahatchee river watersheds’ water quality monitoring results for total phosphorus (TP) and total nitrogen (TN) by basin are presented in Appendix 8C-1 of this volume as supplemental information. ST. LUCIE ESTUARY WY2018 total annual rainfall across the Tier 1 Contributing Areas (Lake Okeechobee, St. Lucie Basin, and Tidal Basin) to the St. Lucie Estuary (SLE) was more than the long-term average from WY1997 through WY2018. Although 74% of the annual rainfall usually occurs in the wet season, this value increased to 80% in WY2018. The relatively high amount of wet season rain was the driver for increased discharge to the SLE. The total annual freshwater inflow to the SLE in WY2018 (1.6 million acre-feet [ac-ft]) was higher than the long-term average of 1.0 million ac-ft. The inflow and percent contribution from Lake Okeechobee in WY2018 (0.6 million ac-ft and 37%, respectively) were greater than the long-term averages (0.3 million ac-ft and 26%, respectively).

  • Kissimmee Chain of Lakes Highlights
    KISSIMMEE CHAIN OF LAKES HIGHLIGHTS FLORIDA FISH AND WILDLIFE CONSERVATION COMMISSION 1601 Scottys Road, Kissimmee FL 34744 Aquatic Habitat Conservation & Restoration Section (407) 846-5300 www.MyFWC.com August 13, 2004 2004 Lake Tohopekaliga Extreme Drawdown & Habitat Enhancement Project Has Concluded Prior to flood control in the mid 1960’s, aquatic vegetation and organic material did not accumulate along the shoreline due to a natural cleansing process that occurred during flood and drought events. For the past 17 years, stabilized water levels on Lake Tohopekaliga have resulted in a build-up of aquatic vegetation along the shorelines. Over time, the aquatic vegetation died and decomposed which contributed to the build-up of muck along the shorelines. Once the muck accumulates, more aquatic and terrestrial vegetation becomes rooted on top of the muck. This process leads to less available open water in the lake and sometimes results in the formation of floating islands known as tussocks. These tussocks can cause serious problems as navigational hazards for boaters, diminish desirable fish and wildlife habitat and threaten water control structures. To set-back lake succession, the extreme drawdown and muck removal project was planned. In November 2003, with all permits and plans in place, the South Florida Water Management District (SFWMD) began to lower Lake Tohopekaliga’s water level from 55 ft National Geodetic Vertical Datum (NGVD) down to 49 ft NGVD. With the water level down, prescribed burning was initiated in densely vegetated areas of the lake. Meanwhile, heavy equipment including bulldozers, front-end loaders, track-hoes and dump trucks carried the undesirable vegetation and muck out of the lake or to designated in-lake disposal islands.
