High Quality Content by WIKIPEDIA articles! Baskett Slough National Wildlife Refuge is located in northwestern Oregon, 10 miles (16 km) west of Salem in Polk County. Situated in open farmland near the eastern foothills of the Oregon Coast Range with the broad Willamette Valley and the Cascade Range to the east, elevations range from 185 to 414 feet (56 to 126 m) MSL. The Willamette Valley, with its mild, rainy winter climate, is an ideal environment for wintering waterfowl. The valley was once a rich mix of wildlife habitats with extensive wetlands, meandering stream channels and vast seasonal marshes.
