Hey and Associates Inc. will be conducting the annual spring beach herbicide treatment Monday morning at both Main Beach and West Beach swimming areas in Crystal Lake.
Both swimming areas will be treated with a granular form of selective aquatic herbicide to control submersed aquatic vegetation and with a granular formulation of an algaecide to treat chara, a type of algae that grows in the shallower areas on the lakebed.
Residents should not swim in treated water for a minimum of 24 hours after application. Do not use lake water from the public beaches for irrigating plants, as drinking water or for mixing sprays for agricultural or ornamental plants for a period of seven days from the application date. Fishing will not be restricted after application.
The treatment is weather permitting. For information, contact Hey and Associates, Inc. at 847-740-0888.
