The park board shut down the popular Southeast Beach on Lake Harriet Tuesday after testing showed high levels of potentially dangerous E. coli bacteria in the water.

In a news release, the Minneapolis Park and Recreation Board said the high E. coli levels are likely the result of hot weather and heavy rains over the weekend.

The E. coli levels off Southeast Beach reached 2,420 Tuesday, nearly double the 1,260 level that triggers a shutdown.

The bacteria levels will be tested again Wednesday. Once the levels are within state limits, the beach will reopen.
