Description - McNary NWR is a resting and feeding area for up to 100,000 migrating waterfowl. It includes 3,629 acres of water and marsh, croplands, grasslands, trees, and shrubs.
- McNary NWR features migrating waterfowl such as Canada geese, mallards and American wigeon. They generally have population peaks on the refuge in November. Longbilled curlews and white pelicans are spring and summer residents. There is the chance for wildlife observation and study at the refuge. An Environmental Education Center is available and is staffed by refuge employees and volunteers.
Recreation - There is a self-guided wildlife trail available to visitors. During hunting season, waterfowl and upland bird hunting is allowed. Fishing for largemouth black bass, catfish and crappie is also present on the refuge.
Climate - The climate of Washington varies within each region. The Cascades split the state and alter the weather patterns. The mountains receive large amounts of wet, heavy snow from October through May. These peaks remain snow covered throughout the year. The terrain east of the mountains receives approximately 12 inches of rainfall per year, generally much less than west of the mountains. Since the area east of the mountains is landlocked, temperatures in this region are lower during the winter months. Frequent winds coming down from the mountains also contribute to the low temperatures of eastern Washington.
Due to the coastal geography, western Washington is primarily temperate. The proximity to the ocean stabilizes the climate, making extreme temperatures very rare. The area receives large amounts of precipitation from Pacific rain and snow storms.
McNary NWR is located southeast of Pasco off U.S. Highway 12 just south of the Snake River. The Refuge visitor facilities are a quarter mile east of Highway 12 on Maple Road.
