The stream gauge measures the water level, flow rate, and temperature. The Cheyenne River is fed by several tributaries, including Owl Creek, Antelope Creek, and Medicine Root Creek. There are no major dams on the Cheyenne River, but there are several smaller ones that help control the flow of water. The river experiences seasonal trends, with the highest flows occurring during the spring and early summer months due to snowmelt and runoff. The hydrology of the Cheyenne River is an essential aspect of the ecosystem, sustaining wildlife, vegetation, and the economy of the surrounding area.
