Connecticut environmental officials say the beach at Squantz Pond State Park has been closed to swimmers because of blue-green algae that can emit toxins possibly harmful to people and dogs.
The Department of Energy and Environmental Protection says it's monitoring the water at the New Fairfield beach to assess conditions. Water samples are being tested to determine the level of toxins and when the area will be safe for swimming. The swimming area will be closed at least through the weekend.
Blue-green algae, also known as cyanobacteria, occur naturally in lakes and ponds. The microscopic organisms often go unnoticed and cause no harm but when temperatures are high and high levels of phosphorus are carried into water from storm runoff, blue-green algae blooms may be produced and release toxins.
