Algae Treatments at Indian Lake and Coes Pond

For Immediate Release: 7/21/2021 10:24 pm

The City of Worcester’s Department of Public Works & Parks has contracted for the application of copper sulfate to Indian Lake and Coes Pond on Thursday, July 22.

This preventative treatment is unrelated to the closings of Shore Park Beach and John J. Binienda Memorial Beach at Coes Pond as the result of high bacteria levels. The treatment is a safe and effective way to control the growth of harmful, toxin-producing algae. The application of copper sulfate is a common practice to maintain a healthy lake, and poses minimal risk to humans and animals after application is complete.

The application is coordinated with the Indian Lake and Tatnuck Brook Watershed Associations and has been approved by the Worcester Conservation Commission.

On the day of the treatment, all individuals are advised to stay out of the water, discontinue boat use and fishing, and keep their pets out of the water. Indian Lake Beach, Shore Park Beach and John J. Binienda Memorial Beach at Coes Pond will be closed for the treatment. The boat ramp at Morgan Park will also be closed. Indian Lake and Coes Pond are planned to reopen the following day.
