Tests this week show E. coli levels at Sandy Hook and Winnipeg Beach were within recreational water quality guidelines, according to Manitoba Conservation and Water Stewardship.
E. coli counts were above the guidelines on July 9 but quickly returned to below the guideline by July 11. Elevated levels of bacteria were likely caused by wind and wave action washing bacteria out of the sand and into the water.
The provincial department also reported today an algae bloom was observed at Killarney Lake beach, and results showed the number of blue-green algae cells was above the guideline on July 9. The concentration of the algae toxin microcystin was below the recreational water quality guideline.
Algae advisory signs are posted at Pelican Lake (Ninette) and Killarney Lake beach.
People are also advised to avoid swimming in water where severe algae blooms are visible and to prevent pets from drinking water along the shoreline.
Swimmer’s itch advisory signs are posted at Moose Lake Provincial Park, Winnipeg Beach (Lake Winnipeg) and Gull Lake.
