WLBCR Updated AIS Plan

On May 16, 2020 the WLBCR Lakes Association board approved an updated AIS Plan. The plan was updated on June 22, 2020 to include information on mystery snails and crusty crayfish. The plan acknowledges and follows the Cass County AIS Prevention and Management Plan as approved by the Cass County Board of Commissioners on 3/20/2020 and supports the Minnesota state law: Clean your watercraft, Drain all water, Dispose of unused bait. The plan identifies general strategies to be implemented to educate property owners and the public, in order to greatly reduce or prevent AIS from entering the lakes.
