Dear SLA Membership and friends of Skaneateles Lake,
PLEASE SEE BELOW RE: INFORMATION ON IDENTIFYING & REPORTING HABs AND ADVISORIES ON SWIMMING, WATER USE, AND EXPOSURE AS RECOMMENDED BY NYSDEC AND NYSDOH.
After receiving an alert from MidLakes Navigation, Skaneateles Lake Association Staff, trained by the New York State Department of Environmental Conservation (NYSDEC) in shoreline monitoring, recently observed a "Localized" Harmful Algal Bloom (HAB) Tuesday, August 23, 2022.
- Zone 3525 near Village Docks at 8:56 AM
- (still visibly present as small surface bloom as of 12:00 PM on 8-23-22)
More observations may have been submitted to DEC via NYHABS.
Bloom conditions could persist or change based on continuation of sunlight, high temperatures, and lack of wind.
The report of the small localized bloom is based on visual observations. The City of Syracuse confirmed presence of Microcystis colonies that sometimes can produce toxins. City of Syracuse additionally conducts testing to determine if toxins are present in the municipal drinking water. If conditions in the municipal drinking water supply warrant a public health advisory, one will be issued by the Onondaga County Health Department. Information from NYSDEC and NYSDOH regarding further recommendations related to HABs can be found below.

Please share with the community. SLA will send more confirmed information along as it becomes available.
According to the NYSDEC:
People, pets and livestock should avoid contact with any floating mats, scums, or discolored water. Colors can include shades of green, blue-green, yellow, brown or red.
Never drink, prepare food, cook, or make ice with untreated surface water, whether or not algae blooms are present. In addition to toxins, untreated surface water may contain bacteria, parasites, or viruses that could cause illness if consumed.
People not on public water supplies should not drink surface water during an algal bloom, even if it is treated, because in-home treatments such as boiling, disinfecting water with chlorine or ultraviolet (UV), and water filtration units do not protect people from HABs toxins.
Blooms can change locations and dissipate rather quickly, so it is important to use your best judgement when deciding to use the water and to keep an eye out for new bloom locations. See pictures at the bottom of this email to identify HABs and refer to this website:

According to the New York State Department of Health:
Exposure to any cyanobacteria HABs can cause health effects in people and animals when water with blooms is touched, swallowed, or when airborne droplets are inhaled. This is true regardless of toxin levels; some blue-green algae produce toxins, while others do not. Exposure to blooms and toxins can cause symptoms such as diarrhea, nausea or vomiting; skin, eye or throat irritation and allergic reactions or breathing difficulties. People and pets should avoid contact with blooms, and should rinse off with clean water if contact occurs. For more information go to www.health.ny.gov/harmfulalgae.
