The river flows through the Willamette Valley and has several small tributaries, including Quartzville Creek and the North Santiam River. The Foster Dam, located upstream, can also impact flow levels. Seasonal trends show higher flows in the winter and spring due to increased rainfall and snowmelt, and lower flows in the summer and fall. Interesting facts about the hydrology include the presence of old growth forests along the river, which can slow down water flow and filter out pollutants. Additionally, the river is a popular spot for fishing and recreation.
