The Grand Coulee Dam is seen from the day use park by the Grand Coulee Dam Visitor Arrival Center. The Grand Coulee Dam, located on the Columbia River in central Washington, is the largest concrete structure in the United States. It forms the centerpiece of the Columbia Basin Project, a multipurpose endeavor managed by the U.S. Bureau of Reclamation. In addition to producing up to 6.5 million kilowatts of power, the dam irrigates over half a million acres of Columbia River Basin farm land and provides abundant wildlife and recreation areas.
