About Us

What We Do

The Tualatin River Watershed Council is a partnership: individuals and organizations work cooperatively to improve the health of the watershed for fish, wildlife and people. We are composed of people who live, work or recreate in the Tualatin River Basin as well as organizations that have an interest in the area. 

The Watershed Council coordinates our efforts with many private and public sector partners to produce the greatest benefits for the watershed. We believe that cooperative efforts and relationships will produce lasting benefits for everyone involved. Our habitat restoration projects and basic operations are funded by grants, matching funds from partners and contributions from community members.

Our History

Founded by local residents in 1993, the Watershed Council is an independent, non-profit corporation. The Watershed Council is composed of people from the local communities, representing local knowledge of the watershed and its complexity. The Watershed Council works across jurisdictional boundaries and across agency mandates to look at the watershed more holistically. 

The Council is a forum to bring local, state, and federal land management agencies and plans together with local residents. The Council provides local people with a voice in natural resource management that can significantly influence watershed management decisions.
