Boise project, in the Boise, Payette, and Snake river valleys, SW Idaho and E Oregon; developed in 1905 by the U.S. Bureau of Reclamation for irrigation, hydroelectricity, flood control, and recreation. The project has turned the area into major U.S. seed-producing and dairying regions. Anderson Ranch, Arrowrock, and Boise dams are the principal facilities of the project's Arrowrock division, located between the Snake and Boise rivers. The Payette division, between the Payette and Boise rivers, includes Black Canyon, Cascade, and Deadwood dams.
