WORCESTER—Indian Lake undergoes a preventative treatment Monday to curb the potential growth of harmful algae, according to the city’s Department of Sustainability and Resilience.
Contractors hired by the city apply copper sulfate, an algaecide commonly used to control toxin-producing algae. The application is scheduled for Sept. 22 and has been approved by the Worcester Conservation Commission.
While there is currently no threat of harmful algae exposure, officials advise residents to stay out of the water, suspend boat use, and keep pets away during the treatment. Water from the lake should not be used for irrigation or livestock on the day of application. Access points will be posted, and restrictions are expected to be lifted the following day.
City officials said copper sulfate is a safe and effective way to help maintain a healthy lake and poses minimal risk to people or animals once treatment is complete.
Additional information about cyanobacteria, also known as blue-green algae, is available through the city’s video series “The Blue Space Minute” at this link.
