Blue-green algae blooms could be back on Ramsey Lake

Sudbury's health unit is investigating possible blue-green algae blooms in Ramsey Lake.

The health unit says if a bloom is present, people should not swim, drink or let their pets go in the lake.

Blue-green algae looks like pea soup and has a foul smell. It produces toxins that can irritate skin or cause diarrhea and vomiting.

Sudbury's drinking water supply is not affected, the health unit adds.

The Ministry of theEnvironment and Climate Change is testing Ramsey Lake water samples to confirm if a bloom has happened.
