State Removes Cyanobacteria Warning for Locke Lake, Barnstead Angle Pond, Sandown & Hampstead And Monomonac Lake, Rindge NH & Winchendon MA
Concord, NH – The cyanobacteria cell concentration at the following waterbodies is below the state standard of 50% of the total cells:
- Locke Lake, Barnstead
- Angle Pond, Sandown & Hampstead
- Monomonac Lake, Rindge NH & Winchendon MA
As a result, the New Hampshire Department of Environmental Services (DES) has removed the cyanobacteria warnings issued between May 26 and 27.
DES routinely monitors public beaches and public waters of the state for cyanobacteria. DES monitors public waters issued cyanobacteria warnings on a weekly basis until the cyanobacteria standards are again met. Cyanobacteria are natural components of water bodies worldwide, but blooms and surface scums may form when excess phosphorus is available to the water. Some cyanobacteria produce toxins that are stored within the cells but released upon cell death. Toxins can cause both acute and chronic health effects ranging in severity from skin and mucous membrane irritations, nausea, vomiting, and diarrhea to liver and central nervous system damage for humans and animals.
Visit the DES Beach Program website at http://des.nh.gov/organization/divisions/water/wmb/beaches/index.htm for photos and more information about cyanobacteria. Updates on advisories and warnings may be obtained at http://www2.des.state.nh.us/Advisories/Beaches/
If you notice anything resembling cyanobacteria, please refrain from wading, swimming, or drinking the water. Keep all pets out of the water and contact DES immediately. Please call DES to report a cyanobacteria bloom at (603)419-9229
