It might be harmful blue-green algae if you see: strongly colored water, paint-like appearance, floating mats or scum.

If you are not on a public water supply, household water treatment such as Ultraviolet (UV), boiling or chlorinating will not make your water safe for use. During a bloom, do not drink, prepare food, cook, or make ice with water from the lake or from beach wells.
Never drink untreated surface water.
Visually monitor the water near your beach well daily and call Environmental Health with questions: 607-274-6688.
Never swim, fish, boat, wade or eat fish caught in water with blooms.
If you see a bloom, avoid it and wait 24 hours after the bloom is no longer visible before swimming or having contact with the water.
Pet owners should keep their pets away from water experiencing algae blooms. If animals ingest the toxins either through drinking or cleaning their fur after exposure, they can become sick quickly. Call your veterinarian if your pet comes in contact with a bloom.
If you see a suspicious bloom, stay out of the water and report the bloom to the NYS Department of Environmental Conservation at HABsInfo@dec.ny.gov.
Rinse thoroughly with clean water to remove algae, including dogs that may have gone in the water.
Stop using water and seek medical attention immediately if symptoms such as vomiting, nausea, diarrhea, skin, eye or throat irritation, allergic reactions or breathing difficulties occur after drinking or having contact with blooms or untreated surface water.
Report any HAB-related health symptoms to the NYS Health Department at firstname.lastname@example.org, or call TCHD Community Health Services at (607) 274-6604.
