District to treat hydrilla on Rainbow River

News Release

The Southwest Florida Water Management District will be treating hydrilla on the Rainbow River from the Withlacoochee River to upstream of the Rainbow Springs State Park Campground during the week of November 2-6.

Treatment involves the spot application of the aquatic herbicide Aquathol Super K to scattered infestations. Treatment areas will be posted with warning signs displaying treatment dates and applicable water use restrictions. Treated river water should not be used for drinking, irrigating or domestic use within seven days of treatment. Water use restrictions apply to treated river water only, not tap or well water.

Hydrilla is a troublesome invasive aquatic plant, which was introduced into Florida waters during the late 1950s. It is a fast-growing plant that expands quickly. If not controlled, recreational activities, navigation, flood control and fish and wildlife populations are negatively impacted. The management of hydrilla on the Rainbow River is a cooperative effort between the District, the Florida Fish and Wildlife Conservation Commission and the Florida Department of Environmental Protection.

For more information, please call the District at 352-796-7211 or 1-800-423-1476, ext. 4537.
