State Removes Cyanobacteria Lake Warning for Forest Lake, Winchester, NH

CConcord, NH – The cyanobacteria cell concentration in Forest Lake in Winchester, NH, is below a level of public health concern. As a result, the New Hampshire Department of Environmental Services (DES) has removed the cyanobacteria lake warning issued on July 28, 2011.

DES routinely monitors public beaches and public waters of the state for cyanobacteria. Once a cyanobacteria lake warning has been issued, DES returns to affected waterbodies 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 that range in severity. Acute health effects include irritation of skin and mucous membranes, nausea, vomiting, and diarrhea. Chronic effects include liver and central nervous system damage.

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/
Follow the Beaches twitter feed:http://twitter.com/NHDES_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.
