Lake Red Rock


Lake Red Rock is Iowa's Largest Lake with over 15,000 acres of water and 35,000 acres of land for your enjoyment.  Located on the Des Moines River just 45 miles southeast and downriver from Des Moines, the reservoir collects runoff and and drainage from over 12,320 square miles of Iowa and southern Minnesota land.  This protects communities and agriculture lands downstream from the Red Rock Dam.  The maximum flood control pool is 780 feet above sea level, over 33 miles long, and covers 65,500 acres.  Other lake area benefits include numerous recreational opportunities and natural resources on the water and surrounding public lands.

Swimming Not Recommended at North Overlook Beach
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. Further information on the Corps of Engineers water quality monitoring procedures may be obtained at the Red Rock Visitor Center.
