WORCESTER – Coes Reservoir will undergo treatment for harmful algae on Thursday, July 11.

According to the City of Worcester, the treatment is preventative and there is no current threat of harmful algae.

Residents are advise to take the following precautions at Coes Reservoir on Thursday:

  • Stay out of the water;
  • Discontinue boat use and fishing;
  • discontinue using water for:
    • irrigation of plants or lawns
    • watering livestock

A contractor hired by the city’s Department of Sustainability and Resilience will apply the treatment of algaecide copper sulfate to the reservoir. Copper sulfate is a safe and effective way to control the growth of harmful, toxin-producing algae and poses minimal risk to humans after the application is complete.

The treatment was approved by the Worcester Conservation Committee.
