MINNEAPOLIS (WCCO) — Three Minneapolis beaches are temporarily closed as a precaution after a sanitary sewer backed up in St. Louis Park.

The beaches affected are all around Cedar Lake — they include Cedar Lake East Beach, Cedar Lake Point Beach, and Cedar Lake South Beach. Signage will be posted there by Tuesday morning.

City of St. Louis Park crews responded to clean up the area as best as possible, the Minneapolis Parks and Recreation Board reported. But they report it’s uncertain how much water made it to the St. Louis Park storm sewer system that flows through Twin Lake Pond and Twin Lake, to Cedar Meadows Pond, and into Cedar Lake.

This news comes after Bde Maka Ska Thomas Beach and Lake Hiawatha Beach were closed last week, when samples indicated elevated E. coli levels. The bacteria was likely due to Sunday’s rainfall, which brought stormwater into the lakes.
