Algae warning signs removed at Belwood Lake

Warning signs advising people to be cautious around the water due to health risks associated with blue-green algae were removed from Belwood Lake park.

A sample collected from the boat launch area within the park on Aug. 17 showed non-detectable levels of microcystin.

Lake users should continue to avoid algae mats on the shoreline, “scum” floating on the surface or any other visible algae. The blue-green algae are the source of microcystin.

The warnings went into effect on Aug. 12 after water samples from the reservoir showed levels of microcystin higher than those recommended for recreational use. The signs were posted by Wellington-Dufferin-Guelph Public Health.

Microcystin, a toxin released by blue-green algae, can cause skin rashes after contact or illness after being ingested by people or animals.

GRCA staff will continue to monitor the reservoir and provide updates as necessary.
