Lake Apopka Timeline

Early History

Historians do not agree as to when the first human settlers arrived in the Lake Apopka area. Aboriginal culture, especially on the northeast shore of the lake has been documented occurring continuously from at least 10,000 B.C. to about 400 A.D. These unnamed tribes were undoubtedly ancestors to the natives thriving in the area when the Spanish arrived. The Spanish called them Timucuans. Historic outfall from the lake was primarily through Double Run Swamp on the west side of the lake, to Lake Harris. By the mid 1800's, white settlers began farming the south shores.

Lake Apopka has experienced dramatic changes in its environmental health over the past century. A once plentiful and productive lake, the second largest lake in Florida, was a renowned fishing paradise where anglers from all over the world came hoping to land a trophy bass. The clear, pristine lake was home to 29 fish camps on its 40 miles of shoreline.

This changed, starting in 1941, with the establishment of 20,000 acres of vegetable muck farms. The filtering marshes on the north shores were drained to make room for the farms. Massive quantities of nutrients were pumped into the lake from the farms, municipal sewage, and effluent from citrus processing. The high nutrient loading encouraged widespread algae blooms, blocking sunlight and choking productive submerged plants and causing a decline in game fish populations. Clean up measures failed. Eventually, only undesirable fish feeding on the algae could survive in these extreme conditions.

The fish camps all closed and the “green” lake became known as the most polluted large lake in Florida. This condition has endured for more than 40 years. In 1991, The Friends of Lake Apopka (FOLA) organized, advocating the restoration of the lake. This broad based citizens group appealed to agricultural interests to change their farming practices, and sought public support to restore the lake. After years of work FOLA endorsed the Lake Apopka Restoration Act of 1996 in the Florida Legislature. This led to the $100 million public purchase of the muck farms to stop the nutrient pollution flow. St. Johns River Water Management District is the Florida public agency charged with the responsibility of purchasing the farms and restoring the lake. 

The restoration of the lake has began, although it is anticipated to be a slow, complicated process. At the end of the decade of the 1990’s, measurement of water quality variables indicate the condition of the lake improved more than 30%. However, the unprecedented scale and complexity of the restoration will be challenges for years to come. Cumulative pesticide residues, unexplained bird fatalities, involvement of the Federal Government and urban development, are all part of the scientific, political and economic landscape of restoration.

FOLA continues actively advocating a healthy lake, supporting efforts for recreational trails and access to the lake, development guidelines to control pollution from development, and a rule to decrease future phosphorous discharge to the lake. All citizens must continue to monitor and be informed about the progress of the restoration

Lake Apopka Timeline

1880 Construction of the Apopka - Beauclair Canal started by Apopka Canal Company to create a waterway for navigation and agricultural use.

1883 Lake levels drop three feet and expose sediment surface of marshes. Small farms spring up around lake.

1885 Land around the lake was going for the high price of 25¢ per acre because people expected future demands for property in the area.

1893 Delta Canal Company successfully completes 12 miles of canal connecting Lake Apopka through Lakes Beauclair, Dora, Eustis, and Griffin to the Ocklawaha River. This lowered the water surface of Lake Apopka by approximately 1 meter, exposing the sediment surface of most of the sawgrass marsh on the north shore.

1894 Category I hurricane passes over lake.

1895 Disastrous freezes kill more than half of the citrus trees in Orange County.

1910 Due to crop failures because of difficulty in water table management and cold waves, canal becomes filled with vegetation and lake stage returns, more or less, to its normal levels.

1915 Zellwood Produce Company improves the canal to reduce water table fluctuations. Farmers on the south shore protest, fearing water supply shortages, decreased cold protection and threatened navigation.

Conceptual plan for full-scale Marsh Flow-Way completed.

Several small patches of eelgrass observed near north shore.

1996 The Florida Legislature passed legislation introduced by Kelly, Sublette, and Dyer. The Lake Apopka Restoration Act of 1996 set a phosphorus criterion for the lake, giving SJRWMD the legal authority to set a phosphorus discharge limitation and providing $20 million to acquire northern shore farm land.

Up to $26 million guaranteed by federal government under the Dept. of Agriculture NRCS2 Program.

1997 Design of full-scale Marsh Flow-Way approved. Construction initiated with $3.53 million contract.

1998 $100 million buyout of almost 15,000 acres of muck farms is completed, with funding from the State of Florida, and 25% from the U.S. Federal Wetlands Reserve Program. Farming and pesticide applications cease with the last farm crop, June, 1998.

SJRWMD begins reflooding the former marshes and their restoration and hopes for restoration of the Lake are high.

Gizzard shad harvesting continues with 6.5 million pounds of shad harvested since 1993.

First draft restoration plans for farm lands presented to public.

1999 Massive bird migrations visit the area with over 175 different species logged. Sudden, large scale avian deaths brings intervention of U.S. Fish and Wildlife and Department of Justice. Residues and accumulations of pesticides are the suspected culprits. Restoration efforts are delayed pending results of scientific and other investigations. Realization of the complexity of restoration becomes a reality.

Measurement of water quality variables indicate a 30% improvement in Lake Apopka for the average of the prior five years, as compared with the early 1990’s. Oakland Nature Preserve is established with an initial purchase of 95 acres.

2000 Scientists continue to study the complexities of muck soils and pesticide residues to design the restoration program. A three year drought lowers lake levels to a record low of 62 above sea level. With the help of the Lake Apopka Steering Committee and professional land planners, FOLA recommends Land Development Guidelines to the eight political jurisdictions in the basin. FOLA spearheads the cooperation of the municipalities and Orange and Lake counties to plan for greenways, trails, and ecotourism and recreational opportunities around the Lake.

2002 June – July - Approximately 700-acres of the Duda property were re-flooded creating habitat for migrating birds. No bird deaths associated with the re-flooding have been reported. The flooding also allows SJRWMD to store water on the North Shore Restoration Area.

2003 Phosphorus limitation rule is passed by SJRWMD with support from FOLA.

FOLA completes Greenways and Trails design project, which includes a loop trail around the lake.

October 8, 2003 - Memorandum of Understanding was agreed upon by USFWS and the District creating a framework for future restoration of the former farmlands.

November 2003 – Phase I of the marsh flow-way begins operation on the North Shore Restoration Area and treats approximately 50% of the lake’s volume of water during its first year of operation.

The remaining Duda fields (except for one) were re-flooded. Totaling approximately 1,700 acres reflooded.

2004 On April 13th, an intergovernmental agreement was signed between the District and the Lake County Water Authority for the use of the 225-acre CC Ranch parcel for their Alum Treatment Facility on the Apopka - Beauclair Canal. FOLA objects. The CC Ranch parcel was bought in 1992 with Preservation 2000 funds for restoration.

2005 Ferndale Preserve, a 192-acre acre parcel on the northwest shore of Lake Apopka was purchased with funding from SJRWMD, Lake County, Lake CountyWater Authority and a grant from Florida Communities Trust. The Preserve is part of the FOLA Master Plan for the Lake Apopka basin.

On November 18, the City of Apopka applied for a Consumptive Use Permit that proposes withdrawing 5 million gallons of water a day from Lake Apopka and the North Shore Restoration Area to supplement reuse for irrigation. FOLA objects.

2006 October, FOLA celebrates the 10-year anniversary of the signing of the bill for the restoration of Lake Apopka with a ceremony at the Oakland Nature Preserve honoring those who played a major role in supporting the bill.

December, 700-acres of the Duda property was re-flooded creating habitat for migrating birds. No bird deaths associated with the re-flooding have been reported.

2007 As of July, more than 13,750,000 pounds of gizzard shad have been harvested since the program began in 1993. This translates into removal of about 96,000 pounds of TP by simply removing the fish. In addition 1,000,000 pounds of shad are estimated to produce about 25,000 pounds of TP per year.

After years of studies on residual pesticides, deep soil inversion was begun in the North Shore Restoration Area.

In April, two of the four treatment cells of the Marsh Flow-Way were drained for maintenance. These cells were successfully re-flooded nine months later and began treating lake water again.

2008 Phase 1, a 1,200-acre parcel, was the first section of the former ZDWCD farm area to be flooded for wetland restoration after completion of research following the bird mortality. Soil Inversion work in the North Shore Restoration Area continues.

The gizzard shad program removed 1,601,056 lbs. from Lake Apopka.

November, the remaining two of the four treatment cells of the Marsh Flow-Way were drained for maintenance. These two cells were successfully re-flooded nine and twelve months later.

2009 The District completed deep soil inversion on 4,000 acres of highly contaminated land, at a cost of approximately $2,500 per acre. The remediation resulted in a 68% average reduction of DDE. The District flooded Phase 2 (1,400 acres) for wetland restoration. The District also began construction of infrastructure to allow controlled flooding of the remainder of the former farm area for wetland restoration.

The Marsh Flow-Way treated 2.5 times the volume of Lake Apopka since November 2003. Total removals from 2003 to December 2009 are 62 million lbs. of suspended solids and 37,300 lbs. of total phosphorus.

Gizzard Shad program removed only 674,803 lbs. reflecting an effective reduction of gizzard shad biomass in Lake Apopka. Experimental gill net catches of gizzard shad for Lake Apopka in February and March were the lowest on record.

City of Apopka receives a consumptive use permit for reuse water from the North Shore Restoration Area.

The restrictions and conditions on the permit place the restoration of the Lake and North Shore Area as a priority before water will be available to the City of Apopka. FOLA stand firm in our commitment against surface water withdrawal.

Harris Chain Council publishes a negative report on the restorations efforts of Lake Apopka and the North Shore Restoration Area that is met with a great deal of criticism based on lack of scientific evidence and misuse of data.

2010 In October the lake concentration of total phosphorus averaged 76 parts per billion, closing in on the target goal of 55 ppb.

October – shad harvesting began and 650,000 pounds of shad had been harvested when the season completed December 31. Toward the end of the season the fish size declined rapidly, and catch rates were much lower for a second year in a row. This is a good sign that populations of gizzard shad are decreasing. Sunshine bass were released into the lake to feed on the smaller shad, which is a major part of their natural food chain.

Restoration of wetlands on the North Shore Restoration Area reduces discharge to Lake Apopka and related nutrient loading, accelerating the restoration of the lake. Approximately 5,000 acres have been reflooded.

Infrastructure construction is completed and as the biological assessments are completed, with U.S. Fish and Wildlife, saturation and restoration flooding may begin creating a wide range of water levels on the North Shore Restoration Area. Monitoring of soil pesticides concentrations will be on-going.

A study of mercury contamination in Florida shows mercury levels in Lake Apopka fish significantly lower than other water bodies in the state.

Because of low lake levels and forecast low rainfall, SJRWMD reduced discharge at the Apopka, Burrell, and Moss Bluff structures during the winter to help protect lake levels from falling even lower.

2011 The total list of bird species observed on the north shore of Lake Apopka is 346, highest total for any site in Florida (even greater than Everglades National Park with 340 species).

Minimum discharges resumed at all the basin structures on May 2 and in February Lake Apopka was up 3.6 inches.

The Marsh Flow-Way has filtered 3.1 volumes of lake water since it began in 2003. The Flow-Way has removed tons of suspended solids, nitrogen and phosphorus to date.

The District hopes to get approval to flood the remaining acres in the fall of 2012.

Increased expansion of exotic apple snail.

FOLA has concerns over several issues being proposed:

  • Changes by Fish and Wildlife Services in policy for controlling Hydrilla.
  • Airport adjacent to the North Shore Restoration Area
  • Sewage Compost Facility in Lake County near Beauclair Canal.

2015 The district opened an 11-mile, self-guide wildlife drive at its Lake Apopka North Shore property in Orange County, expanding opportunities to view wildlife and restoration of the lake's wetlands. A portion of the wildlife drive intersects with the Lake Apopka Loop Trail where hikers, bikers and other users share the road.
The Lake Apopka Wildlife Drive is open year-round between sunrise and sunset on Fridays, Saturdays, Sundays and federal holidays. There is no cost to visit the wildlife drive. 

2016 April  A new 2 mile segment of recreational trail opens in Lake County that connects the Green Mountain Scenic Overlook and trailhead with the Apopka Loop Trail.

2016 June Volunteers plant 1,000 Cypress trees in the Lake Apopka North Shore Restoration Area.
