🏢 Terminal Guide & Navigation
Grand Coulee Dam Airport (GCD), identified by the FAA as 3W7, is a publicly-owned general aviation facility located in Electric City, Washington. Serving as a specialized gateway to the Grand Coulee Dam and the surrounding Coulee Region, the airport features a single 4,200-foot asphalt runway. Its location is critical for supporting the operations of the Bureau of Reclamation at the dam—the largest electric power-producing facility in the United States—as well as providing access for utility crews, emergency services, and recreational pilots exploring the Columbia River and Lake Roosevelt.
The infrastructure at Grand Coulee Dam Airport is basic and primarily unattended, designed for functional and self-sufficient aviation operations. The facility includes a modest passenger/pilot waiting room that provides essential weather shelter, a public restroom, and a flight planning area for pilots. While the airport lacks the commercial amenities of larger hubs, such as on-site dining or extensive retail, it offers a small retail shop and a designated parking area for visitors. The terminal environment is quiet and informal, reflecting its role as a utility and recreational hub in a rural part of Washington state.
Ground transportation from the airport into Electric City and the Grand Coulee Dam site is straightforward, with the town's main commercial district and local hotels located just a short drive away. While there is no formal airport shuttle or regular bus service, travelers can typically arrange for local taxi services or utilize pre-arranged private transport. As a single-terminal, unattended facility, there are no inter-terminal transfers, and all transitions between aircraft and ground transport occur within a very compact footprint. Visitors are advised to coordinate their arrivals in advance, as the airfield serves primarily as a landing site for specialized dam operations and general aviation tours of the Columbia River engineering landmark.
Airlines Serving GCD
💡 Connection Tips
Grand Coulee Dam Airport (GCD), also known as Electric City Airport, is a public-use facility located in the stunning coulee country of eastern Washington. There is currently no scheduled commercial airline service at GCD; it serves as a critical base for general aviation, scenic tours, and emergency medical flights supporting the local community and the Grand Coulee Dam operations. For travelers requiring commercial flights, the nearest major hub is Spokane International Airport (GEG), located approximately 90 miles to the east, or a 1. 75 to 2-hour drive through the scenic shrub-steppe landscape. For those arriving at GCD via private aircraft, the facility offers a 2,500-foot paved runway.
Because the airport is unattended, there are no on-site terminal services, baggage handling, or on-demand ground transportation. It is essential to pre-arrange any pickups with a local contact or use the regional transit services provided by Grant County and Okanogan County, though these often require advance notice. The town of Electric City and the visitor center for the Grand Coulee Dam are just a short drive away, offering local dining and lodging options. Weather in the region can be characterized by high summer temperatures and occasional strong winds through the coulee, which pilots should factor into their flight planning.
During the winter, the airfield may have limited snow removal, so checking current NOTAMs is mandatory. While the airport provides an unparalleled aerial view of the largest power-producing facility in the United States, it is a destination where the traveler must take full responsibility for their own logistical 'connections' to the surrounding area. Always carry extra water if visiting during the summer peak, as the high desert environment can be intensely hot.
