The health unit is advising residents of the mid-western side of Leonard Lake and north end of Black Lake, both in Muskoka Lakes Twp. and the west side of Kahshe Lake, in Gravenhurst, about  confirmed blue-green algae blooms.

The Simcoe Muskoka District Health Unit is asking residents and visitors to exercise caution where blue-green algae is visible and not to use the lake water for drinking or the preparation of infant formula.

The health unit says you should be cautious about eating fish caught in the affected water where a blue green algae bloom exists.

Residents are advised not to use herbicides, copper sulphate or other algaecides that may break open algae cells and release toxins into the water and avoid swimming and other water sport activities where an algae bloom is visible.

Symptoms from consuming toxins from a blue-green algae bloom can include headaches, fever, diarrhea, abdominal pain, nausea and vomiting, and can be more serious if water is swallowed in large quantities.

PLEASE NOTE: the health unit originally reported the algae bloom was on the southeast side of Leonard Lake - the correct area is the mid-western side.
