The swimming beaches at three Missouri state parks have been temporarily closed due to bacteria levels. Grand Glaize Beach, also known as Public Beach #2, at Lake of the Ozarks State Park and the public beaches at Mark Twain and Harry S Truman state parks have been temporarily closed following results of water samples taken Monday that indicated bacteria levels higher than those recommended for waters used for swimming. Lake of the Ozark State Park’s Public Beach #1, which is located in Kaiser, is open, and so is the campground beach at Truman State Park.
