Release no. 18-044

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 high bacterial population at the North Overlook Beach, 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.

Due to rising lake levels, the South Overlook Boat Ramp, Volksweg Trail near the Red Rock Marina, and Whitebreast Beach have been closed. Parking at the Marina Cove is very limited due to the high lake level. There is a moderate amount of floating debris in the lake - please use caution while boating. For the most current lake level, dam outflow and forecast information go to
