The Southwest Florida Water Management District (District) will be treating the invasive aquatic plant hydrilla on the Rainbow River in Marion County during the period of November 2-5.

District workers will treat scattered infestations on the lower portion of the river downstream of the CR 484 bridge.

 

Workers will apply the aquatic herbicide Aquathol Super K and post informational signs in the treated areas noting treatment dates and applicable water use restrictions.

There are no restrictions on the use of treated water for swimming, fishing, boating, watering livestock or irrigating established turf, ornamental plants and crops. Treated river water should not be used for potable water or for irrigating annual nursery or green house crops including hydroponics and newly seeded or transplanted annual crops, newly seeded or transplanted ornamentals, and newly sodded or seeded turf for seven days following treatment. Water use restrictions do not apply to well or tap water.

Hydrilla is a troublesome aquatic plant from Southeast Asia, which escaped into Florida waters during the late 1950s. It is a fast-growing plant that expands quickly. If it is not controlled, native plant populations, recreational activities, navigation, flood control and fish and wildlife habitat can be 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.
