Coulee Dam was founded by the U.S. [[Bureau of Reclamation]] in 1933, to serve as headquarters for the construction of the [[Grand Coulee Dam]]. The Okanogan County portion was known as Mason City, location of the head contractor. The portions in Douglas and Grant Counties were known as Engineers Town and were government-owned. In 1942, with the end of the contract in sight, CBI transferred control of Mason City to the Municipal Division of the Columbia Basin Project. In 1948, Mason City was incorporated into Coulee Dam. The government began the process of selling the town to the public in 1957, finishing in 1959. Coulee Dam was officially incorporated as a town on February 26, 1959.

It is the headquarters of [[Lake Roosevelt National Recreation Area]] and home to one of the world's largest man-made piles of sand, a {{convert|12000000|cuyd|m3|adj=on}}, {{convert|230|ft|m|adj=on}}-high hill remaining from dam construction.
