Location
The Upper Missouri River Basin refers to the Missouri River and all its tributaries upstream of Sioux City, Iowa. The basin contains parts or most of five states -- Montana, Wyoming, South Dakota, North Dakota and Nebraska -- and more than 20 Indian reservations. It represents 30 percent of the wheat produced in the United States, 13 percent of the soybeans, 11 percent of the cattle and 9 percent of the corn, according to the Upper Missouri River Basin Association.
The Upper Missouri River Basin also contains the Colstrip power plant in eastern Montana -- the second largest coal-fired generating facility west of the Mississippi -- and the Bakken shale formation.
