All three beaches on Cedar Lake in Minneapolis are closed as a precaution after a sanitary sewer backup in St. Louis Park.
The Minneapolis Park and Recreation Board (MPRB) temporarily closed Cedar Lake East Beach, Cedar Lake Point Beach and Cedar Lake South Beach on Monday and signage is being posted at the beaches Tuesday morning.
The City of St. Louis Park caught the sanitary sewer backup "quickly" and crews responded to clean up the area "as best as possible," the MPRB said. However, it's not clear how much water made it from the system that flows through Twin Lake Pond and Twin Lake to Cedar Meadows Pond and into Cedar Lake.
The MPRB says they'll test all Cedar Lake beaches on Tuesday and Wednesday, and will update its beach lake water quality map when the beaches reopen.

Meanwhile, all the other MPRB public beaches are open, including the two that were closed last week due to high levels of E. coli.
MPRB and other entities in the state routinely monitor lake water quality and proactively close beaches if bacteria levels exceed state guidelines. You can find a list of counties and organizations in Minnesota that monitor and test beaches here.
