NH DES LIFTS OFFICIAL CYANOBACTERIA ADVISORY

The NH DES Province Lake Cyanobacteria Advisory was lifted on Aug 30. Please click here for details.
NH DES informed the PLA that the cyanobacteria found can produce anatoxins but they do not analyze for toxicity. As a precaution, you should use judgment and avoid areas where a bloom occurs (bright green mats, stringers) as shown on our website.
