Red Rock Lake
Iowa's largest lake, with 19,000 surface area of water. The Red Rock Dam was authorized by the U.S. Congress for flood control purposes. After nine years of construction, the U.S. Army Corps of Engineers completed the mile long earthen dam in 1969. Red Rock has become a premier location for enjoying uncrowded outdoor recreation opportunities. At the lake's standard elevation of 742 feet above sea level. When heavy rains occur on the lake's 12,000 square mile watershed, the
lake can triple in size.
Flooding in 1984 pushed the lake to a height of 779.62 feet above sea level, creating a 65,000 area lake. Red Rock Yacht Club calls this lake home.
