Tualatin River National Wildlife Refuge, National Wildlife Refuge in Washington County, Oregon

Tualatin River National Wildlife Refuge is a federally protected area in Washington County, Oregon, covering wetlands, ponds, and floodplain along the Tualatin River. It borders several communities in the greater Portland area and is made up of flat, low-lying land crossed by water channels and edged by dense vegetation.

The refuge was established in 1992 after decades of drainage and farming had removed much of the original wetland cover from the Tualatin Valley. Its creation brought together federal agencies, local groups, and communities around Portland in a shared effort to recover the land.

The refuge sits close to a large urban area, and many local residents treat it as a place to watch birds and walk among wetlands without traveling far. During migration seasons, birdwatchers gather along the trails to spot species that pass through only briefly each year.

The refuge is open daily during daylight hours, but the visitor center keeps limited hours, so checking ahead before you go is a good idea. Early morning is the best time to see birds, especially in spring and fall when migratory species stop here.

The refuge began with 12 acres of woodland donated in late 1992 by neighbours Tom Stibolt and Lisa Brenner, who bought the plot beside their own property and gave it to the project. Sherwood added a 1-acre parcel in 1993, and Congress approved $2 million that November to buy more land.
