The Ontario County Health Department has issued a warning that blue-green algae blooms have been found in Canandaigua Lake.
The health department says some varieties are toxic to humans and dogs, and it’s asking people to avoid contact with the water if they see the water is discolored or has a scum on top.
They also say boiling and treatment with chlorine at home don’t remove the toxin, so people shouldn’t drink water directly from the lake.
