The Department of Natural Resources closed the Grand Glaize Beach at the Lake of the Ozarks due to high levels of E. Coli bacteria.
Four other beaches in the state have also been closed after the department tested water samples taken Monday.
Public Beach #1 at the Lake remains open to swimmers.
The department will re-test the water at Grand Glaize Beach again next week.
