were in favor of creating a Missouri Valley Authority (MVA). They claimed that the MVA would provide a more unified solution to water development on the Missouri River than the merged ideas of opposing bureaucracies. Ideas for the MVA were influenced by the success of the Tennessee Valley Authority. Senator James E. Murray of Montana and Congressman John J. Cochran from Missouri developed bills for the Missouri Valley Authority. The MVA bills planned to navigate Missouri into a number of stairstep lakes linked together by locks. They would also arrange for giant reservoirs to supply irrigation and cheap hydroelectricity power, arguing that this would produce more public power and leave less condemned private land. The bills were presented in the 79th Congress, but they were later brought down. Interventions Several water-control measures were introduced through the Pick–Sloan legislation that variously affected the Missouri River Valley and its environs. The Pick–Sloan program dams built between 1946 and 1966 are: Canyon Ferry Dam and Lake in Montana Garrison Dam and Lake Sakakawea in North Dakota Oahe Dam and Lake Oahe in South Dakota Big Bend Dam and Lake Sharpe in South Dakota Fort Randall Dam and Lake Francis Case in South Dakota Gavins Point Dam and Lewis and Clark Lake in South Dakota and Nebraska Based on Pick–Sloan legislation, the Reclamation Project Authorization Act of October 20, 1972 authorized the Bureau of Reclamation to built additional dams at the North Loup River and Middle Loup River in Nebraska: Six dams were constructed between 1976 and 1994: Davis Creek Dam Virginia Smith Dam and Calamus Lake (formlery Calamus Dam and Reservoir) at the Calamus River Kent Diversion Dam Sherman Dam and Reservoir Milburn Diversion Dam Arcadia Diversion Dam Other dams along the Missouri River that were not part of the Sloan–Pick program are Toston Dam (1940), Hauser Dam (1907), Holter Dam (1908), Black Eagle Dam (1927), Rainbow Dam (1912), Cochrane Dam (1958), Ryan Dam (1915), Morony Dam (1930) and Fort Peck Dam (1940), all located in Montana. Native American relocation Over 200,000 acres on the Standing Rock Indian Reservation and the Cheyenne River Reservation in South Dakota were flooded by the Oahe Dam, forcing Native Americans to relocate from flooded areas. 21,497 acres of Indigenous land were flooded by the Fort Randall Dam and 20,478 acres destroyed by the Big Bend Dam.
