  • Swimming Not Recommended at North Overlook Beach

Sampling at the beaches is performed weekly by the Corps of Engineers through a contract with Iowa State University.

While this week's test results showed elevated bacterial population at the North Overlook beach, the Whitebreast Beach and the main body of the lake had low bacterial counts. Further information on the Corps of Engineers water quality monitoring procedures may be obtained at the Red Rock Visitor Center.
