    The state of New Hampshire has issued a warning about blue-green algae blooms in Lake Monomonac in Rindge, discouraging people from having contact with the water.

    The warning was issued Monday. Once the Department of Environmental Services issues a cyanobacteria warning, it returns to affected areas on a weekly basis until the bloom is not evident.

    Cyanobacteria are natural components of waterbodies, but blooms and surface scums may form when excess phosphorus is available to the water.

    Some cyanobacteria produce toxins that can cause problems ranging from skin irritation to nausea, vomiting, and diarrhea. Chronic effects include liver and central nervous system damage.
