The river is a tributary of the Columbia River and flows through northern Washington State. Important constituents of the flow include snowmelt and precipitation. There are several dams along the river, including the Okanogan Dam and Zosel Dam, which can affect the flow. Seasonal trends show a peak in flow during the spring and early summer due to snowmelt, and lower flows during the fall and winter. The hydrology of the Okanogan River is interesting because it is an important salmon spawning river, and also has a unique geologic history that has resulted in unique rock formations along the river banks.
