Warning signs advising people to be cautious around the water due to health risks associated with blue-green algae are being removed from Belwood Lake Park.
A sample collected from the boat launch area within the park on Wednesday showed non-detectable levels of microcystin.
Lake users should continue to avoid algae mats on the shoreline, floating on the surface or any other visible algae. The blue-green algae are the source of microcystin.
The warnings which went into effect last friday were posted by Wellington-Dufferin-Guelph Public Health.
Microcystin is a toxin that is released by blue-green algae as they die. It can cause skin rashes after contact or illness after being ingested by people or animals.
Algae blooms are a natural phenomenon. They tend to occur during hot dry weather, often increasing in frequency during late summer and early fall.
GRCA staff will continue to monitor the reservoir and provide updates as necessary.
