Fort Randall Dam is a concrete dam located on the Missouri River in South Dakota. Completed in 1953, it was built primarily for flood control, irrigation, and hydroelectric power generation. The dam creates Lake Francis Case, a large reservoir that supports recreational activities such as fishing and boating. The dam is operated by the U.S. Army Corps of Engineers and plays a crucial role in managing water flow in the region. It helps to regulate river levels, ensuring safety for nearby communities while also providing water for agricultural use. The facility contributes to the local economy through recreation and tourism.
