River and its tributaries, draining an area of c.513,300 sq mi (1,329,400 sq km) in Nebraska, Montana, South Dakota, North Dakota, Wyoming, Kansas, Missouri, Colorado, Iowa, and Minnesota. The program provided for the construction of 112 dams with a storage capacity of almost 35 million gal/132 million liters; 4,300,000 acres (1,740,000 hectares) of irrigated land; 2.6 million kilowatts of hydroelectric generating capacity; a 9-ft (2.7-m) navigable channel on the Missouri River from Sioux City to its mouth; control of floods and sedimentation; protection of fish and wildlife; and development of recreational facilities and industrial and municipal water supplies. Seven main-stem dams on the Missouri were completed (Fort PeckFort Peck Dam,
21,430 ft (6,531 m) long and 250 ft (76 m) high, on the Missouri River, NE Mont.; one of the world's largest earth-filled dams. The dam was built (1933–40) by the U.S. Army Corps of Engineers as a flood-control and navigation-improvement project.

The program has been modified and expanded over the years and is integrated with other projects for the region, including the Colorado–Big Thompson projectColorado–Big Thompson project,
constructed by the U.S. Bureau of Reclamation to divert water from the headstreams of the Colorado River to irrigate c.720,000 acres (291,400 hectares) of land in NE Colorado and to supply power; built 1938–56.
