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.

Missouri River Energy Services Officially Breaks Ground on Red Rock Hydroelectric Project
PELLA, Iowa – The official groundbreaking of the Red Rock Hydroelectric Project (RRHP) took place Aug. 13 at Lake Red Rock near Pella, Iowa. The project is a retrofit of an existing Army Corps of Engineers dam on the Des Moines River that will produce 36 megawatts of power, with the capacity to generate up to 55 megawatts during peak seasons; enough to power about 18,000 homes. Missouri River Energy Services (MRES) is building the project, which is being financed by Western Minnesota Municipal Power Agency (WMMPA). RRHP is expected to be completed in 2018, at which point it will be the second-largest hydropower facility in Iowa.

T-15 will be down to one lane relating to construction of hydroelectric project
One lane of T-15 that crosses over the Red Rock Dam will be closed so that workers can safely widen that section of road in order to add a turning lane. The widened road and turning lane will give workers access to the future intake structure for the Red Rock Hydroelectric Project that will be constructed at the dam. Signage indicating the one-lane closure will be placed at each end of the dam. Traffic will be limited to one lane each weekday between the hours of 7 a.m. and 5:30 p.m., beginning Tuesday, Aug. 19. It is hoped that the work will be completed by Friday, Aug. 28. Both lanes of the road will be open on Saturday and Sunday. The road will be completely closed later in the fall. Missouri River Energy Services (MRES), which is building the Red Rock Hydroelectric Project, will issue a notice prior to that closure. MRES also has developed a website at www.redrockhydroproject.com that will include up-to-date information about the project. For more information, contact MRES Director of Member and Public Relations Bill Radio, phone: 605-338-4042; e-mail: bill.radio@mrenergy.com.
