Tualatin River Facts

Our river

Protecting public health and the Tualatin River is at the heart of our work. The 80-mile-long Tualatin River is unlike most rivers in the Northwest. It meanders slowly through relatively flat terrain, draining more than 700 square-miles of forested, agricultural and urban areas before joining the Willamette River. The Tualatin is Washington County's only river and an important resource to the region. The river is used for regional drinking water supply and agricultural irrigation. In addition, canoeing, fishing, and wildlife viewing draw thousands of outdoor enthusiasts each year. Watch the video below to see how we are working for the river.
