State Removes Cyanobacteria Warning for Forest Lake, Winchester
Concord, NH – The cyanobacteria cell concentration at Forest Lake, Winchester is below the state standard of 50% of the total cells. As a result, the New Hampshire Department of Environmental Services (DES) has removed the cyanobacteria warning issued on July 16th.
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 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.

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
