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.
