The river's main constituents are runoff from precipitation, snowmelt, and groundwater. The river has several tributaries, including the West Branch Knife River, Silver Creek, and Stewart River, and there are no major dams on this river. The flow rate varies throughout the year, with the highest flows in spring and early summer due to snowmelt and precipitation, and the lowest flows in the winter. Interesting facts about the hydrology of the river include the presence of glacially-formed terrain, which affects the river's channel and flow dynamics.
