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.

Scott McEwen
Executive Director

Scott joined the Tualatin River Watershed Council in 2018. For the past decade and a half Scott has been a conservation leader in the Pacific Northwest. Prior to his work with the Council, Scott served for nine years as the Conservation Director for Columbia Land Trust where he and his team permanently protected over 15,000 acres of threatened habitats in both Oregon and Washington. He also served for three years as the Director of Technical Programs overseeing habitat restoration and ecosystem monitoring programs for the Lower Columbia Estuary Partnership.

Scott is passionate about understanding, conserving and restoring the diverse habitats of the northwest. His background in the Clean Water Act, Safe Drinking Water Act, and species recovery programs in combination with his technical knowledge have resulted in the development of effective and enduring programs. When he is not at work, you can find Scott white water rafting with his family or plying the area’s estuaries and rivers with his kayak or canoe.

Antonella Fillet
Project Manager

Antonella’s fondness for the outdoors and conservation work began in early high school, through her high school’s outdoor education programs. During college, Antonella spent a summer leading backpacking trips with the Opal Creek Ancient Forest Centers Expedition Program. It was here that she solidified her love for the outdoors and began to seek out any opportunity to get outside. In 2020, Antonella graduated from the University of Portland with a B.S. in Environmental Science and minors in Environmental Ethics & Policy and German.

Upon graduating, Antonella began working as a Project Manager at Native Plantscapes NW, a small restoration company based out of Hillsboro, OR. The last few years, Antonella has worked in the field, getting hands on experience with invasive weed control, native plant replanting, seed collection, and erosion control. These experiences have fostered her interest and passion to continue working in conservation. Antonella joined Tualatin River Watershed Council in 2023 and is excited to begin this new chapter of work. In her free time, Antonella can be found bouldering or playing beach volleyball!
