NO RECREATIONAL WATER ACTIVITY AT LAKE MASSAPOAG - EFFECTIVE IMMEDIATELY

A visible suspected cyanobacteria scum was just found and reported to the Massachusetts Environmental Toxicology program, which requires posting of no water activity signage and immediate closure of the lake. Please rinse off well at home as soon as possible.

The lake will remain closed until cleared by Mass DPH. Homeowners with lake access must also refrain from entering the water for any recreational activity.

Below are some resources to learn more about cyanobacterial blooms, including how they can be deadly for pets and livestock.

• CDC fact sheet: Cyanobacterial blooms and animals:  https://www.cdc.gov/habs/pdf/algal-bloom-poster-8.5x11-p.pdf

We will post updates as necessary. Thank you for your patience as we navigate this situation.
