The Pick–Sloan Missouri Basin Program, formerly called the Missouri River Basin Project, was initially authorized by the Flood Control Act of 1944, which approved the general comprehensive plan for the conservation, control, and use of water resources in the entire Missouri River Basin.
The intended beneficial uses of these water resources include flood control, aids to navigation, irrigation, supplemental water supply, power generation, municipal and industrial water supplies, stream-pollution abatement, sediment control, preservation and enhancement of fish and wildlife, and creation of recreation opportunities.
It derives its name from the authors of the program -- Lewis A. Pick, director of the Missouri River office of the United States Army Corps of Engineers, and William Glenn Sloan, director of the Billings, Montana office of the United States Bureau of Reclamation.[1]
