JEFFERSON CITY, MO, JULY 27, 2011 – Visitors to Lake of the Ozarks State Park’s Grand Glaize Beach can once again jump into the water, beat the summer heat and have fun at the lake this weekend following the latest water sample results.

"The public is becoming very familiar with our website and the beach status information posted on the web," said Bill Bryan, director of Missouri State Parks, a division of the Missouri Department of Natural Resources. "So, it was no surprise that when our park staff arrived to reopen the Grand Glaize beach they were met by 20 swimmers who had already checked the website and were ready to go swimming."

The Grand Glaize Beach reopened today after water samples taken Monday showed bacteria levels well below the department’s acceptable levels for state park beaches.

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.

Information about current status of beaches at other parks is available on the website at Signs indicating the status of the beaches are posted at the beaches as well.

Beaches and other facilities at state parks may be unavailable for reasons unrelated to bacteria, such as the beach at Lewis and Clark State Park, which remains closed due to flooding. Missouri State Parks maintains a list of alerts and advisories at
