PLATTSBURGH — The Clinton County Health Department is advising residents to be on the look-out for Harmful Algal Blooms (HABs) at local swimming areas.

Point au Roche State Park announced Monday that their swimming area would be closed until further notice due to HABs.

Ryan Davies, Director/Engineer of CCHD’s Environmental Health and Safety Division said.

HABs are the rapid growth of cyanobacteria, or algae, that can cause harm to people and animals. They can look like foam, scum, paint, or mats on the surface of the water.

These blooms produce toxins that can make people or pets sick.

HABs are most likely triggered by a combination of conditions that include: excess nutrients (phosphorus and nitrogen), lots of sunlight, low-water or low-flow conditions, calm water, and/or warm temperatures.

Depending on the weather and the characteristics of the lake, HABs may be short-lived (appearing and disappearing in hours) or long-lived (persisting for several weeks or more).

Davies said.

¯ 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.

¯ Don’t 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 HAB toxins.

¯ If contact does occur, rinse thoroughly with clean water to remove algae. 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.
