Four state park swimming beaches have been temporarily closed for water quality issues, according to the Missouri Department of Natural Resources. The state park beaches at Finger Lakes, Columbia, Harry S. Truman State Park, Warsaw, and Wakonda State Park, La Grange, are closed following results of water samples taken Tuesday that indicated bacteria levels higher than those recommended for waters used for swimming. Earlier this week, the state park beach at Thousand Hills, Kirksville, closed due to flooding. The beach remains closed due to flooding as well as high bacteria levels. The campground beach at Harry S. Truman State Park remains open. Visitors to Harry S. Truman State Park may stop by the office or fee booth to obtain a pass free of charge to swim at the campground beach. Once tests from the four state park beaches indicate the bacteria levels are within the standard suitable for swimming, the beaches will reopen. The department collects water samples from all designated beaches in the state park system weekly during the recreational season to determine suitability for swimming. The sample test results indicate a snap shot of the water quality taken at the beaches at a specific time, however, a single sample does not provide an overall sense of the water quality in the lake where the beach is located. DNR will post the information about the beach status on the website at dnr.mo.gov as well as mostateparks.com. Visitors to Missouri State Parks are able to sign up to receive free electronic notices about the status of state park beaches while visiting the department’s beach status website.
