The Southwest Florida Water Management District will be treating hydrilla on the Rainbow River from the head spring to the Withlacoochee River during the week of April 19–23.
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, domestic use or irrigation for seven days following treatment. Water use restrictions apply to treated river water only, not to tap or well water.
Hydrilla is a troublesome exotic aquatic plant, which escaped into Florida waters during the late 1950s. It is a fast-growing plant that expands quickly. If it is 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 Department of Environmental Protection and the Florida Fish and Wildlife Conservation Commission.
For more information, please call the District at (352) 796-7211 or 1-800-423-1476, ext. 4537.
