The Missouri Department of Natural Resources has issued a swimming advisory has been issued for Grand Glaize Beach at Lake of the Ozarks State Park due to high bacteria levels.

The Missouri Department of Natural Resources has issued a swimming advisory has been issued for Grand Glaize Beach at Lake of the Ozarks State Park due to high bacteria levels.

Water samples taken this week from the Osage Beach area public beach tested above the state advisory level for E. coli. The advisory indicates swimming is not recommended.

While bacteria levels were high at GGB during this week’s sampling, Lake of the Ozarks State Park Public Beach #1 were below the acceptable levels.

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.

According to DNR, 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 can frequently be associated with heavy rains; however, there are a number of other sources that may contribute to elevated bacteria levels, which may pose a health risk. And as quickly as the levels can rise, they can fall. Meaning a beach that samples high on one day may be not show any elevated levels within even hours of the testing.

Some level of bacteria is always to be expected, and even swimming pools can be hazardous due to the time it takes for chlorine to kill bacteria.
