Lake Tohopekaliga, Kissimmee: The Lake That Rewrote the Rules of Restoration

In the mid-1980s, fisheries biologists looked at Lake Tohopekaliga and proposed something audacious. They wanted to drop the water level by several feet, expose the lake bottom to the sun, and physically scrape the accumulated muck off the shoreline — not on a hundred-acre pond where that kind of thing had been tried before, but on a 22,000-acre lake. Nobody had ever attempted muck removal on a body of water remotely that big. The Orlando Sentinel reported in 1986 that the technique had worked on small residential lakes like 100-acre Lake Hunter, but Toho was a different animal entirely. The biologists pushed anyway. They believed the lake was suffocating under decades of organic sediment, and that if it wasn't intervened on, the bass fishery and the wading-bird habitat that defined Big Toho would keep sliding.

The drawdown happened in 1987, and it became something of a spectacle. Top state officials came out to watch. The Department of Environmental Regulation put $248,000 into the project, $100,000 of which had been collected through environmental fines elsewhere in Central Florida — pollution money, in effect, recycled into restoration. Crews moved out onto the dried lake bottom and hauled away the soft, black, nutrient-loaded sediment that had been smothering the sandy substrate where bass spawn and where bulrush and maidencane want to root. Photos from the period show heavy equipment sitting on what is normally lake bottom. For people in Kissimmee who had only ever seen Toho as water, the sight was disorienting.

What made the project matter beyond Osceola County was that it worked well enough to become a template. The drawdown-and-scrape model — drop the lake, expose the muck, remove the worst of it, burn or grade the shoreline, then let the water come back — has since been repeated across the Kissimmee Chain and on lakes throughout Florida. East Lake Toho got the same treatment. So did Lake Kissimmee downstream. The Florida Fish and Wildlife Conservation Commission still lists managed drawdowns, organic sediment removal, and prescribed burns as core tools for shallow-lake habitat enhancement. All of that has its proof-of-concept moment on the west side of Kissimmee in 1987.

The reason Toho needed it in the first place is its own story. The lake sits at a low point in a chain that drains a huge piece of Central Florida — Shingle Creek runs 23 miles down from the Pine Hills area of Orlando before emptying in, and the Boggy Creek headwaters reach all the way back to what's now Orlando International Airport. As Orlando grew, every fertilized lawn, every wastewater plant, every paved acre upstream sent its load south. By the late 20th century, secondary effluent from nearby cities was flowing in, cyanobacteria that had existed only at trace levels were blooming, and the lake bottom kept getting softer and deeper in muck. The 1980s wastewater diversions cut the phosphorus inputs sharply. The drawdown handled what was already on the bottom.

Toho's reputation today as one of the best bass lakes in the country — host to multiple Bassmaster Classics, the headquarters of a tournament economy that fills hotels in Kissimmee on weekends most anglers couldn't tell you about — rests on that 1987 decision. Without the drawdown, the spawning flats that produce trophy largemouth would have stayed buried. The lake would still be here, but it would fish like a different lake.

The work isn't finished. In March 2024, the Sentinel reported that hydrilla had taken hold on West Lake Toho in one of the worst infestations in Central Florida, and that there wasn't money to eradicate it. The lake that pioneered large-scale freshwater restoration is back in the queue for the next round of intervention. That's the rhythm of a working Florida lake — you don't fix it once. You keep fixing it. Shoreline conditions shift with every drawdown and refill, which is part of why seawalls and dock heights on Toho have to be built with that fluctuation in mind.

The Seminole word tohopke means fence or fort. Likv means site. Fort site. People love to translate it as "we will hold it here," which isn't quite right linguistically but captures something true about the place anyway. In 1987, a group of biologists and state officials decided to hold this lake here — to refuse to let it slide into something muck-bound and dying — and the way they did it changed how Florida thinks about saving a lake.
