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.
The beaches are tested for E-Coli bacteria. Most forms of these bacteria are harmless, but they indicate contamination that could lead to illness such as flu-like symptoms.
While this week’s test results showed high bacterial population at the North Overlook Beach, the main body of the lake and Whitebreast Beach had low bacterial counts.
