The Florida Fish and Wildlife Conservation Commission (FWC) is planning to treat hydrilla, an invasive aquatic plant, in portions of Lake Tohopekaliga in the week beginning Monday, Nov. 9. The scheduled treatment is subject to weather conditions.

The FWC will be treating 1,097 acres of hydrilla with herbicides on Lake Toho, an 18,800-acre lake in Osceola County. There are no restrictions on fishing or swimming in the treated areas.

Hydrilla clogs waterways, making recreational activities difficult or impossible, and chokes out beneficial native plants. Managing and treating it is necessary for the health of Florida’s waters and to enable continued recreational boating and other aquatic activities.

The herbicides being applied are approved for use in lakes by the U.S. Environmental Protection Agency and the Florida Department of Agriculture and Consumer Services.

For questions about this treatment, contact Ed Harris, FWC Invasive Plant Management biologist, at 407-858-6170.
