Swimmers hoping to cool off at three of Minneapolis' most popular beaches on Tuesday instead ran into "Beach Closed" signs. Routine water testing turned up elevated levels of E. coli, prompting park staff to halt public swimming at Bde Maka Ska North Beach, Bde Maka Ska 32nd Street Beach and Lake Hiawatha Beach while they collect follow-up samples and post warning notices. Officials say the spike followed recent heavy rain, and there have been no reports of swimmer illnesses.
According to FOX 9, the Minneapolis Park and Recreation Board closed the three sites on June 30 after lake samples came back above acceptable levels. In an email bulletin, the Minneapolis Park & Recreation Board said the bacteria most likely washed into the lakes from surrounding areas after recent rainfall and confirmed there are no reports of any illnesses.
How park staff monitor and why beaches close
Per the Minneapolis Park & Recreation Board, staff collect E. coli samples at public beaches at least once a week and post closed signs on the Lake Water Quality Map when results exceed state-specified guidelines. The board says bacteria spikes often follow storms and can be driven by stormwater runoff, pet waste and waterfowl. Staff re-sample the water and will only reopen beaches when bacteria levels fall back within acceptable limits.
What swimmers should know
State health guidance advises avoiding swimming for 48 hours after heavy rain, not swallowing lake water, washing hands after coming ashore and staying out of the water if you have diarrhea in order to reduce the risk of recreational water illnesses, according to the Minnesota Department of Health. If anyone believes they became ill after swimming, MDH provides reporting guidance and resources for health concerns.
Where to check updates
The MPRB posts current test results and reopening notices on its Lake Water Quality Map and offers email alerts for beach updates. Check the board’s map for the most recent status. We will update this item as park staff post new sampling results and reopenings.
