The New Hampshire Department of Environmental Services is alerting the public about a reported algae bloom at Willand Pond. The city has posted a sign at the boat launch public access area, and on the Somerworth side at the access point off High Street.

Until an analysis is complete, and out of an abundance of caution, recreational users of Willand Pond should avoid contact and keep pets away from the water, especially areas with surface scum or blue-green or bright green flecks.
