Upper Colorado River Compact
This compact, signed in 1948 by Arizona, Colorado, New Mexico, Utah and Wyoming, was ratified by Congress in 1949. The compact apportions the use of waters of the Upper Basin among the signatory states, and created the Upper Colorado River Commission to administer its provisions. The commission consists of representatives of the United States and each compact state except Arizona, and has an office and staff in Salt Lake City, Utah.
Annual reports of the commission document activities of the commission and streamflow, storage and water development conditions in the Upper Basin. Copies of the annual reports are available for inspection at the commission office in Salt Lake City and the Interstate Stream Commission office in Santa Fe.
