Swimming continues to be not recommended at Lake Red Rock’s Whitebreast Beach and North Overlook Beach due to elevated bacterial counts. The beaches will continue to be posted with “Swimming Not Recommended” signs until further testing indicates low bacteria counts. The main body of the lake had low bacterial counts. Sampling at the beaches is performed weekly by the Corps through a contract with Iowa State University. Further information on the Corps of Engineers water quality monitoring procedures may be obtained at the Red Rock Visitor Center.
