Herbicide Treatment May 30th on Red Rock Lake and Lotus Lake

The Riley-Purgatory-Bluff Creek Watershed District is conducting an herbicide treatment on Thursday, May 30th. Herbicide will be applied to areas with curly-leaf pondweed on Red Rock Lake and Lotus Lake.  The herbicide used will be a low dose of Diquat and would be applied early-season; please see figures below for specific targeted areas.  Application of this herbicide will occur when the treatment will be optimal (low wind action and water temperature close to 50F).

The District recommends that you do not use the water from Red Rock Lake or Lotus Lake for human or animal drinking, and irrigation within 7 days of application. If you would like to opt-out from having treatment occur on your property, please contact Claire Bleser at the below contact information.  Please let us know if you would like to opt-out by May 24, 2019.  The treatment of the lake would be at no-cost to the residents.

Mitchell Lake, Lake Riley and Staring Lake will not be treated based on plant surveys performed earlier in the month of May.
