The health unit is advising people not to swim or fish in Little Lake Park in Midland.
It is concerned about possible blue-green algae in the lake that can be harmful to humans and animals.
Blue-green algae can produce toxins that would result in headaches, fever, diarrhea, abdominal pain, nausea, and vomiting.
In the meantime, the health unit cautions against any activities in the lake, including swimming, bathing, cooking, washing or eating fish caught in the lake.
And because wind and water currents can move the algae blooms, the health unit is cautioning the public about the entire lake.
Please be advised that there is also a swim advisory in effect for Midland’s Pete Pettersen Park Beach.
Please be advised that Little Lake Park Beach is closed until further notice due to a potential blue-green algae bloom discovered by the @SMDhealthunit during beach water testing. For more details, please visit: https://t.co/WSbeG5oI2v pic.twitter.com/GR8BQAGEyc
