Riding Mountain National Park has closed Moon Lake to the public, after blue-green algae was found on the lake’s shore.
This algae produces a toxin that causes serious illness to people and animals who come into contact with it.
Symptoms of blue-green algae poisoning include headache, fever, and skin irritation, among others.
People are being advised to not drink or swim in the lake water. Violators could be fined up to $25,000 under the Canada National Parks Act.
The closure went into effect on Sunday, August 2nd, and will last until August 16th.
