Seasonal trends show decreased flow in winter due to frozen waterways and increased flow in spring and summer as snow melts and rainfall occurs. The river has gained national attention due to protests against the construction of the Dakota Access Pipeline. The hydrology of the river is essential to the environment and the local community, providing a source of water for irrigation, recreation, and wildlife habitat.
