Pittsfield: Onota Lake closing for aquatic treatment

Onota Lake will be chemically treated with a USEPA/MA registered aquatic herbicide on Tuesday, Aug. 15, to control invasive nuisance aquatic vegetation. The entire lake will be closed to all water uses, including swimming, fishing and boating, on the day of treatment. These uses may resume on the morning of Wednesday, Aug. 16.

Use of the lake water for irrigation (watering lawns, gardens or plants of any kind) is prohibited for five days post treatment; drinking and cooking is prohibited for three days post treatment, and watering livestock (i.e. cattle, horses, etc.) is prohibited for one-day post treatment.

Printed posters warning of these temporary water use restrictions are posted around the lake shoreline in advance of treatment.

The work at Onota Lake will be performed for the City of Pittsfield by the state-licensed firm, Solitude Lake Management Inc., of Shrewsbury pursuant to a License to Apply Chemicals from Mass DEP and an Order of Conditions permit from the Pittsfield Conservation Commission.
