WATER TREATMENT WEEK OF 6/22/2020:

2020 Public Beach Herbicide Treatment
(with additional areas along the south shore)

On Monday morning, June 22nd, Hey and Associates, Inc. will be conducting the annual beach herbicide
treatment at Main Beach swimming area. The swimming area 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 lake bed.
Additional areas to receive treatment will be areas adjacent to Gates 3, 13, 15 and will include waters
approximately 50’ off of the shoreline to approximately 100’ offshore. This portion of the application is
due to not being able to treat initially during the June 8

th treatment date.

Do not swim in treated water for a minimum of 24 hours after application. Do not use lake water from
the public beaches (treatment areas) for irrigating plants, as drinking water (human or pet) or for mixing
sprays for agricultural or ornamental plants for a period of 7 days from the application date. Fishing will
not be restricted after application.
Should the weather prevent this treatment from happening on the date listed above, the treatment will
occur on the next business day that the weather allows.
