Cyanobacteria Advisory Removed for Winona

Today the NH Department of Environmental Services (NHDES) removed it’s advisory for Lake Winona following another round of water sampling. No cyanobacteria cells were found. The initial advisory issued on June 19 was not based on a toxin evaluation and was intended as a precautionary measure for short term exposure. Cyanobacteria are natural components of water bodies worldwide, though blooms and surface scums may form when excess nutrients are available to the water.

NHDES advises lake-goers to look out for green surface accumulations in the future. If you should see anything, please contact NHDES immediately at (603) 848-8094 (Beaches/Cyanobacteria Hotline) or They will send someone for a site visit.
