The Florida Fish and Wildlife Conservation Commission (FWC) will conduct aquatic plant control on Lake Rousseau from April 10 through 21, weather permitting.

Invasive hydrilla will be treated in boat trails, and water lettuce and water hyacinth will be treated throughout the lake.

Boat trails requiring hydrilla treatment to maintain navigation include a section of County Trail A, County Trail B, South Shoreline Trail (south of County Trail B), Old Mill Trail and Hamic Estates Trail.

In addition, several boat trails require hygrophila treatment to maintain navigation. These trails are River Retreats, Canoe Trail and Loop, East SE, and Middle SE.  Hygrophila is another exotic, invasive plant that has outcompeted hydrilla in this area of Lake Rousseau.

Biologists anticipate treating about 150 acres of hydrilla, 11 acres of hygrophila and 35 acres of water lettuce and water hyacinth with herbicides approved by the United States Environmental Protection Agency.

“There will be no restrictions on recreational activities, such as fishing or swimming, during the treatment period,” said Bruce Jaggers, an FWC invasive plant management biologist.  “Any edible fish caught that are legal to keep may be consumed.” 

There is a seven-day restriction for using water from treated areas for drinking or for animal consumption. However, there are no restrictions for other uses of treated water such as irrigating turf, ornamental plants and crops.

Hydrilla is an invasive aquatic plant spread easily by boats throughout Florida’s lakes and rivers. While recreational anglers and waterfowl hunters may see some benefits from hydrilla, there are other potential impacts to consider including negative impacts to beneficial habitat, navigation, flood control, potable and irrigation water supplies, recreation and the aesthetic qualities of lakes. The FWC strives to balance these needs while managing hydrilla.
