CONCORD, NH (AP) – State officials are warning of potentially dangerous algal blooms at two bodies of water with popular recreational areas.
The New Hampshire Department of Environmental Services said Friday it had detected high concentrations of cyanobacteria — also known as blue-green algae — at Mascoma Lake and Goose Pond. The department advises visitors to avoid contact with the water and keep pets away.
Thick clouds of green algae were observed at several spots on Mascoma Lake in Enfield and Lebanon, while green streaks could be seen along the shore at Goose Pond in Canaan and Hanover, the agency said. Water tests confirmed high levels of cyanobacteria.
Algal blooms occur naturally but can be harmful to people and animals, the department said.
Scientists believe a combination of factors can trigger large buds, including warm temperatures, slow water circulation, and excess nutrients, particularly nitrogen and phosphorus. Some flowers produce toxins such as microcystin, which can cause nausea, fever, and liver damage in humans and kill animals.
The notices remain in effect until the department determines that the concentrations have subsided.
