High E. coli Levels Close Two State Park Beaches
JEFFERSON CITY - Two Missouri state park swimming beaches will be closed this weekend due to high E. coli levels. Water samples drawn Monday from public beaches at Wakonda and Lake of the Ozarks state parks showed E. coli levels in excess of the Missouri Department of Natural Resources’s standard for state park beaches.
Wakonda State Park Beach will be closed due to E. coli levels higher than the department’s standard for a single water sample. The testing results of Monday’s sample from the beach showed 387.3 E. coli colonies per 100 milliliters of water.
A water sample collected from the Grand Glaize Beach, or Public Beach No. 2, at Lake of the Ozarks State Park had 325.5 E. coli colonies per 100 milliliters, prompting the department to close it as well. Public Beach No. 1 at Lake of the Ozarks State Park met department standards and remains open.
Mark Twain State Park Beach, which remains closed because of high water, also had E. coli levels in excess of the department standard. A sample collected at the beach had 601.5 E. coli colonies per 100 milliliters of water.
The Department of Natural Resources will close beaches at state parks if a single sample is above 235 E. coli colonies per 100 milliliters of water, which is also the U.S. Environmental Protection Agency’s single-sample guideline for a swimming beach.
The closed beaches have been posted with signs notifying visitors of the closure and will remain closed until E. coli levels fall below the department standard.
