Onota Lake will be chemically treated with aquatic herbicides on Thursday, Aug. 22 to control invasive Eurasian watermilfoil and other nuisance aquatic vegetation.

The lake will be closed to all water uses, (including, swimming, fishing, and boating) on the day of treatment.

These uses may resume on Friday morning, Aug. 23. Use of the lake water for irrigation (watering lawns, gardens or plants of any kind) is prohibited for 14 days post-treatment.

Printed posters warning of these and other temporary water use restrictions will be posted around the lake shoreline in advance of the treatment.
