Beach closures are now a thing of the past at State Park beaches across the state and in the Lake of the Ozarks area. The Department of Natural Resources still tests the water each week during the recreation season, but no longer closes the beach when there is a high bacteria reading. Instead, a sign is posted at the beach which says Swimming is Not Recommended. The DNR can still close a beach if there is a documented health risk from the water. Prior to this, beaches at Lake of the Ozarks State Park and Harry S Truman State Park had been closed for several weeks because of high bacteria readings in the water.
