Oaks Bottom Wildlife Refuge is a 163-acre floodplain wetland that sits along the east bank of the Willamette River, OR, and is the largest remaining natural area within the lower reach of the Willamette-providing necessary habitat for fish and wildlife. Native wildlife populations include threatened salmon and more than 175 species of birds. Everyone is welcome; no experience is necessary. Advanced registration is required!
