The City of Portland sits at the confluence of two of the nations’ major river systems: the Columbia River and the Willamette River. Native salmon, steelhead and other fish and wildlife species live within Portland’s urban boundary, and also migrate through Portland to other parts of the Willamette River Basin, Columbia River Basin, and beyond.
The city is divided into five primary watersheds:
Everyone in Portland lives in a watershed, and many of our daily actions impact the health of our rivers and streams. Portland is a leader in restoring urban waterways, using natural approaches to manage stormwater, and working to recover endangered species. Environmental Services is committed to protecting and restoring our watersheds for clean water, lower infrastructure costs, and making our city more livable and healthy.
