The river is fed by several tributaries, including Battle Creek and West Fork Cheyenne River. There are no major dams on the river, but there are smaller diversion structures for irrigation. Seasonal trends show higher flows in the spring and early summer due to snowmelt, and lower flows in the fall and winter. The hydrology of the Cheyenne River is influenced by the surrounding landscape, which includes the Black Hills and the Great Plains. Interesting features of the river include its role in the history and culture of the Cheyenne people, who have traditionally relied on its waters for sustenance and spiritual practices.
