THUNDER BAY — Test results have confirmed the presence of a blue-green algae bloom at Hazelwood Lake.
The Lakehead Region Conservation Authority posted photos of pea-green algae floating on the surface at the main beach at Hazelwood Lake Conservation Area.
The bloom was reported to the Spills Action Centre of the Ministry of the Environment, Conservation and Parks for testing.
On Wednesday afternoon, the Thunder Bay District Health Unit confirmed the test of a water sample taken on Aug. 14 had come back positive.
Blue-green algae blooms are capable of producing toxins that pose a health risk to people and animals.
When BGA is present in water, it is important to avoid drinking the water, using it for household purposes, and swimming in it.
TBDHU said these precautions should be observed for about 14 days after the algae has dissipated.
Blooms have also developed this summer at Trout Lake and One Island Lake.
Anyone spotting a suspected bloom should contact the Spills Action Centre at (866) 663-8477.
