Shelter Island’s Fresh Pond has been deemed not swimmable by the New York State Department of Environmental Conservation. The DEC has confirmed the presence of a new cyanobacteria bloom, more commonly known as blue-green algae, in the pond, which is dotted with upscale homes along its shores.
Because of these findings, health officials have asked residents not to use or swim or wade in these waters and to keep their pets and children away from the area.
Signs have been posted at the pond’s access alerting Islanders of the risk.
Though blue-green algae are naturally present in lakes and streams in low numbers, they can become abundant, forming blooms in shades of green, blue-green, yellow, brown, or red. The algae may produce floating scums on the surface of the water or may cause the water to take on paint-like appearance.
The DEC advises that contact with water that appears scummy or discolored should be avoided. If contact does occur, rinse off with clean water immediately. Seek medical attention if any of the following symptoms occur after contact: nausea, vomiting or diarrhea; skin, eye or throat irritation; or allergic reactions or breathing difficulties.
