State Warns of Late Season Cyanobacterial Blooms in New Hampshire

Concord, NH - Cyanobacterial blooms have been observed along shorelines of a few lakes and ponds this week. Alerts have been issued (and bloom photos have been shared) for Webster Lake in Franklin, Nippo Pond in Barrington, Danforth Ponds in Freedom, Swains Lake in Barrington and White Oak Pond in Holderness. NHDES advises lake users and their pets to avoid contact with the water in areas experiencing elevated levels of cyanobacteria. Be cautious of lake water that has a surface scum, changes colors, or appears to have green streaks or blue-green flecks aggregating along the shore. Please continue to monitor shorelines for changing conditions and avoid contact.
