A swimming advisory has been issued this week for Public Beach #1 at Lake of the Ozarks State Park due to high bacteria levels. The advisory does not impact Grand Glaize Beach, also a part of Lake of the Ozarks State Park.     Water samples taken this week from PB #1 tested above the state advisory level for E. coli with a geomean result from two samples. The samples were taken on May 21 and May 24. The advisory indicates swimming is not recommended.   The Missouri Department of Natural Resources samples water quality at all designated swimming beaches in the state park system on a weekly basis during the recreational season. The samples are analyzed at the Environmental Services Program laboratory in Jefferson City, and results are posted online.   Water samples are analyzed for E. coli, a common indicator species for bacteria. It is normal for E. coli and other bacteria to be found at naturally-occurring levels in ponds, streams, rivers, lakes and reservoirs. Elevated bacteria levels are frequently associated with heavy rains; however, there are a number of other sources that may contribute to elevated bacteria levels.   Water sample results can help visitors decide whether a particular beach is suitable for swimming, based on the bacteria levels. In accordance with state law, the Missouri Department of Natural Resources will post signs notifying visitors that swimming is not recommended
