Oswego Lake Watershed Council is merging with Tryon Creek Watershed Council to become the West Willamette Watersheds Council (W3). This merger and expansion brings our community-based watershed protection to 48 additional watersheds between Wilsonville and Forest Park. It’s an expansion of land area and stream miles of 500%!

As of November 1, 2026 all donations to OLWC will go to W3. Your support will protect the cool, clean waters of the west Willamette River tributaries for people and wildlife.
