JEFFERSON CITY, MO., JUNE 15, 2011 – The swimming beaches at Mark Twain and Harry S Truman state parks will reopen today, according to the Missouri Department of Natural Resources.

Lake of the Ozarks State Park's Grand Glaize Beach, also known as Public Beach #2, remains closed following results of water samples taken Monday that indicated bacteria levels higher than those recommended for waters used for swimming. The park’s Public Beach #1, which is located in Kaiser, remains open. The swimming beach at Lake Wappapello State Park remains closed due to area flooding.

The water at all designated beaches in the state park system is sampled weekly during the recreational season by the Missouri Department of Natural Resources 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. Water samples are taken to check for E. coli, a common indicator species for bacteria.

Higher bacteria levels are often associated with heavy rains that result in runoff from adjacent lands. However, there are a number of possibilities that can contribute to higher bacteria, and chances are no single source is the cause. Once tests indicate the bacteria levels are within the standard suitable for swimming, the beach will reopen. Information about current status of beaches is available on the website at as well as Signs indicating the status of the beaches are posted at the beaches as well.

Most of the other facilities at these parks remain open and available to the public. A list of facility advisories is available at Missouri's state parks and historic sites offer something to suit everyone's taste - outdoor adventure, great scenery and a bit of history. With Missouri's 85 state parks and historic sites, the possibilities are boundless.
