WORCESTER – The City of Worcester has closed Coes Reservoir, and Coes Pond Beach because of the presence of cyanobacteria containing surface scums.
On Wednesday, city employees identified scum along the Coes Reservoir shoreline.
While, cyanobacteria is naturally occurring, it can be harmful in high densities. The lake will remained closed as further testing is conducted. The lake will continue to be tested for both cyanobacteria and cyanotoxins, and the city will reopen the lake when it is determined safe to do so.
Residents should stay out of the water, discontinue boat use and fishing, and keep pets out of the water until further notice. People and pets should avoid contact with scums.
If you or your pet has had contact with surface scums, wash off with freshwater immediately. If your pet has ingested any of the scums, contact your vet.
The City of Worcester has an active cyanobacteria monitoring and management program intended to keep lakes safe for recreation and wildlife.
