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.
