Irrigation Canals in the Uinta Basin, Whiterocks & Ouray Valley Canal, Duchesne, Duchesne County, UT

Significance: The Whiterocks and Ouray Valley Canal is significant for its impact on a large area of the Uinta Basin. The canal is one of the longest in the basin and has one of the largest carrying capacities. The design and history of construction is a noteworthy example of enlarging an already constructed canal to satisfy the needs of several irrigation companies. Finally, the role of William H. Smart and the Colton family, all prominent figures in national, state, and local politics, contributed significantly to the development of the company and area. A Board of Control, composed of directors from both irrigation companies, was set up to manage and control the jointly used canal. The purpose of joint operation was to secure greater economy and efficiency in use and management of water.
