Grand Coulee Dam (song) Grand Coulee Dam (song) "Grand Coulee Dam" is an American folk song recorded in 1941 by Woody Guthrie. He wrote it during a brief period when he was commissioned by the Bonneville Power Administration to write songs as part of a documentary film project about the dam and related projects. The song was part of the "Columbia River Ballads", a set of 26 songs written by Guthrie as part of a commission by the BPA, the federal agency created to sell and distribute power from the river's federal hydroelectric facilities, in particular the Bonneville Dam and Grand Coulee Dam. On
Columbia River known as the Grand Coulee. After the floods, the river found its present course, and the Grand Coulee was left dry. The construction of the Grand Coulee Dam in the mid-20th century impounded the river, forming Lake Roosevelt, from which water was pumped into the dry coulee, forming the reservoir of Banks Lake. The river flows past The Gorge Amphitheatre, a prominent concert venue in the Northwest, then through Priest Rapids Dam, and then through the Hanford Nuclear Reservation. Entirely within the reservation is Hanford Reach, the only US stretch of the river that is completely free-flowing, unimpeded by dams
