The river is fed by several tributaries, including Gales Creek and Scoggins Creek, and is affected by several dams, including Scoggins Dam and Hagg Lake Dam. Seasonally, the Tualatin River experiences high flows in winter and low flows in summer, with occasional flooding during heavy rain events. Interestingly, the river's water quality is affected by urban and agricultural runoff, as well as wastewater treatment plants. Despite these challenges, efforts are underway to protect and restore the Tualatin River and its habitat for fish and wildlife.
