The river is mainly fed by snowmelt and summer precipitation. The Hells Canyon Dam, located downstream from the gauge, has a significant impact on the hydrology of the river. The river experiences seasonal variations in flow, with peak flows occurring in May and June due to snowmelt. Interesting facts include the river's role as a habitat for endangered species such as the Snake River sockeye salmon and the fact that the Hells Canyon Dam is the deepest gorge in North America.
