The main constituents of the flow are snowmelt and rainfall. The river is fed by several tributaries, including Soos Creek and Newaukum Creek, and is impounded by Howard Hanson Dam upstream of the gauge. The hydrology of the Green River is characterized by seasonal trends, with peak flows occurring in late spring due to snowmelt and winter rain, and low flows in summer and early fall. One interesting fact about the river is that it was once a major spawning ground for salmon, but has been severely impacted by human development and pollution.
