Lower Granite is another of the airports leased from the Corps of Engineers, on the Snake River. Co-located with Lower Granite Lock and Dam, 14 miles south of Colfax, Washington, the airport provides an excellent opportunity for fishing, camping, and educational tours through the dam. Just northwest of the airfield is a large marina, a water recreation area along with a restaurant, bathrooms, camping, and a small motel.
The 3400 foot gravel runway slopes downhill to the northwest. Field elevation is 719 feet and some density altitude problems are encountered during the summer. The canyon is fairly narrow in this area, making patterns difficult. The approach from the east is around a bend in the river. The approach from the west is clear. People and animals have been noted on the runway. The windsock is located midfield on the south side. Strong winds are usually present blowing up or down the canyon, and when the wind blows across the canyon, a windshear can be expected at rimwall height. We recommend an overflight to determine field conditions, and presence of obstructions. Watch for snakes when walking around. The airport is generally open from June 1st to October 1st.
For dam tours, please call in advance to (509) 843-1493, Ext. 255 or Ext. 250.
Note: For security reasons, flying directly over the Dam is not recommended.
