The province is going to retest the water at the lake in Birds Hill Provincial Park, which is northeast of Winnipeg.
This comes after several people reported falling ill after visiting Birds Hill Provincial Park.
The province says the lake’s bacteria levels briefly spiked last week.
Signs at the entrances to the beaches have been posted to warn people about the elevated counts of algae bloom in the lake water.
The province says e.coli densities were also briefly elevated last week but returned to below the recreation guideline by the end of the week.
