Onota Lake Closed For Chemical Treatment Monday

Onota Lake in Pittsfield will be closed to all uses on Monday (Aug. 10^th). A media release from the office of Pittsfield Mayor Linda Tyer says that the Lake will be chemically treated with aquatic herbicides on Monday 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.

According to the media release, the closure will only last a single day, and most uses of the lake will be able to resume on Tuesday morning, Aug. 11th. Use of the lake water for irrigation (watering lawns, garden’s, or plants of any kind) is prohibited for five days after the treatment has been concluded.

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