WORCESTER - The Worcester Department of Public Works and Parks [DPW] contracted with for a preventative application of copper sulfate to Coes Reservoir on Thursday, September 16, 2021.

DPW advises individuals to stay out of the water and discontinue boat use and fishing, and keep their pets out of the water on this day. DPW will post signage prior to application.

The City plans to reopen the reservoir on Friday, September 17.

Copper sulfate is a safe and effective way to control the growth of toxin-producing algae before they multiply to densities that are considered harmful to public health. 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 reservoir is not closed due to a cyanobacteria/blue green algae bloom.
