The main flow providers are snowmelt from the Rocky Mountains and precipitation. Tributaries include the Kettle River and the Pend Oreille River. Dams, such as the Grand Coulee Dam, affect flow and water temperature. Seasonal trends show high flows in the spring due to snowmelt and low flows in the late summer and fall. The Columbia River is a key source of hydroelectric power and irrigation for the Pacific Northwest region. Interestingly, the Columbia River is home to the largest dam removal project in history, with the planned removal of four dams on the lower Snake River to restore salmon populations.
