JEFFERSON CITY, MO, AUG. 10, 2011 – Swimming beaches at Pomme de Terre and St. Joe state parks were closed today after water samples taken Monday showed bacteria levels in excess of the department’s standard.
Hermitage Beach at Pomme de Terre State Park and the beach at St. Joe State Park’s Monsanto Lake were both closed this afternoon and will remain closed until samples tests indicate the bacteria levels are within the standard suitable for swimming.
Pittsburg Beach at Pomme de Terre and the beach at St. Joe’s Pim Lake both remain open to visitors. All other facilities at the two parks are also open and available to visitors.
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. Water quality can be determined to be unsuitable for swimming based on either the single sample taken earlier in the week, or by the geometric mean, which is a mathematical value that takes into consideration results from the current week plus the results taken during the previous weeks.
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.
Information about current status of beaches at other parks is available on the Missouri State Parks website at mostateparks.com
Beaches and other facilities at state parks may be unavailable for reasons unrelated to bacteria, such as Lewis and Clark State Park, which remains closed due to flooding. Missouri State Parks maintains a list of alerts and advisories
