The Cheyenne River is a tributary of the Missouri River, with a length of 295 miles. It has played an important role in the history of the Cheyenne people, who used it for transportation and hunting. The river originates in the Black Hills of South Dakota and flows through the Cheyenne River Indian Reservation before joining the Missouri River. There are several dams and reservoirs along the river, including the Angostura Dam and Reservoir, which is used for irrigation and recreation, and the Belle Fourche Dam, which provides flood control and hydroelectric power. The river is also used for agriculture, particularly for grazing livestock. The Cheyenne River is an important source of water for the surrounding communities and plays a significant role in the ecological and economic well-being of the region.
