Based on surveillance performed July 22, 2022, harmful algal blooms (Blue Green Algae) continue to be observed throughout Conesus Lake. Blooms occur when algae multiply very rapidly over a short period of time, usually in calm, warm water. There are thousands of different algae species; however, a few of these may create toxins. The toxins are a concern when there is a high level present in the water. The Livingston County Department of Health is monitoring for algae blooms and may collect samples of the water if the bloom is concentrated and persistent. Harmful algal blooms may persist in varying degrees and at various locations throughout the summer and fall seasons. The public water supply is safe for drinking.
At this time, visual monitoring has found the presence of harmful algae throughout the lake. Contact with the algae may result in
some health issues such as itching, rashes, fever, headache, upper respiratory symptoms, vomiting and diarrhea. These symptoms are
not just caused by harmful algae contact. If you have any of these symptoms and they persist, you should seek medical advice. You
are advised not to drink or use the lake water for cooking and do not swim, wade, play, or come into direct contact with
water that is discolored or has scums on the surface. Pets should not be allowed to drink or to come into contact with
discolored water. If contact occurs, wash with soap and clean water to remove algal material. Always rinse after coming
into contact with any surface water whether or not a blue-green algae bloom is present. Avoid contact with surface water when open cuts or wounds are present on the body.
Questions may be directed to the Livingston County Department of Health. The Livingston County Department of Health can be reached at 243-7280 Monday thru Friday from 8:00am to 4:00pm or by e-mail: dept-of health@co.livingston.ny.us.
