Lake Red Rock —
Recent bacterial sampling at the North Overlook and Whitebreast Beaches 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, both beaches will be posted with "Swimming Not Recommended" signs until further testing indicates low bacteria counts. The beaches are tested for E-Coli and fecal coliform bacteria. Most forms of these bacteria are harmless, but they may indicate untreated sewage. While this week's test results showed high bacterial population at the beaches, 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.
