The Yellowtail Unit of the Missouri River Basin project is located on the Bighorn River in south central Montana. The key feature of the unit is Yellowtail Dam which rises 525 ft. between the walls of the rugged Bighorn Canyon. The dam, a tall, thin-arch type having a symmetrical double curvature is the highest in the Missouri River Basin. This paper discusses various features of the project construction, including intakes, stilling basin, concrete production, and others.
