Recent bacterial sampling at the North Overlook Beach at Lake Red Rock has shown elevated bacterial counts. Sampling at the beaches is performed weekly by the Corps of Engineers through a contract with Iowa State University. Due to the high readings, the beach will be posted with “Swimming Not Recommended” signs until further testing indicates low bacteria counts. 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.
