Colorado River Storage Project Colorado River Storage Project ARIZONA DEPT. OF LIBRARY ARCHIVES & PUBLIC RECORDS DEC 04 , f The Colorado River-The Colorado is one of the most im• portant rivers in America. It drains one-twelfth the area of the United States. It is fed by the melting snows which, each winter, are piled onto the high Rocky Mountains of the Colorado River Basin. But it flows to the sea through a dry and barren land that can be made fruitful only by irrigation. c r. Dividing the Water-There is not nearly enough water in the Colorado River to irrigate all the land. Thus, an agreement had to be reached on sharing the water among the 7 States of the river basin. The Colorado River Compact of 1922 was the first step. It divided the Colorado River water between the Upper and The Colorado River Storage Project -In A Nutshell ..... ~ Lower Basins at Lee Ferry, Ariz., a point in the river l mile e~ below the mouth of the Perie River. ~ With Lower Basin rights to Colorado River water assured by n the 1922 Compact, rapid development and use of that water (}~ ~ 0 took place in Arizona, California, and Nevada. Hoover Dam, a:... completed by the Bureau of Reclamation in 1935, was the key m ~... to Lower Basin development. Water is now diverted or pumped u :i ... directly from the river at many points downstream from Hoover J! cc Dam. In 1948, the Upper Basin States agreed on division of their share of water available under the Compact. Of the Upper Basin's share of Colorado River water (7,500,000 acre-feet per year), the State of Arizona is apportioned the consumptive use of not to exceed 50,000 acre-feet per annum and the remain• der is allocated as follows: Colorado, 51 % percent; New Mexico, 111,4 percent; Utah, 23 percent; and Wyoming, 14 percent. Upper Basin's Problem-In general terms, the 1922 Compact made a division between the Upper and Lower Basins of the long-time average flow of the Colorado River as measured at Lee Ferry. It specified that the Lower Basin should receive its share of the long-time average flow, even in years when the Colorado's flows are far below average. Thus, in some years, the Upper Basin would be short of water because the Upper Basin gets what is left in those very low-flow years. Herein lies the Upper Basin's problem if needed Upper Basin water• use projects are to be built in the future. Solution for the Upper Basin-The big Storage Unit dams and reservoirs of the Colorado River Storage Project provide the solution for the Upper Basin States. Like huge barrels on the Colorado River and its main tributaries, they will catch and hold surplus water in years of high runoff. Then each year, regardless of whether the runoff is high or low, there will be water in the huge Storage Unit reservoirs for release to Lower Basin water users. With control of the Colorado estab• lished on the main stem and main tributaries, more than 40 projects could be built high on the smaller tributaries in the Upper Basin to divert and use water that is now lost in a few short spring months when the snow melts from the mountains. Upper Basin Participating Projects-Of the more than 40 potential participating projects of the Colorado River Storage Project that may be built in coming years, 6 are now completed, 7 are under' construction, 4 are authorized, and 13 are now being planned. Direct benefits to the people will be realized on these participating projects. They will develop reliable supplies of water for farms, cities, and industries and will be the hard core of an ever-expanding Upper Basin economy. Who Pays for the Colorado River Storage Project?-The Bureau of Reclamation is building the Storage Units and Participating Projects, but the reimbursable costs must be re• paid. Some money will come from the sale of water, but not nearly enough. Much more will come from the sale of hydro• electric power produced at the big dams. The dams' power• plants will be interconnected and also connected with other Federal and public and private utility systems by a Federal transmission system. All income from the sale of water and power will go into the special Upper Colorado River Basin Fund, and annual pay• ments will be made to the Federal Government to repay the project costs and interest, as required by law.

Although the project report has been approved by the Secretary of the Interior there will not be enough copies for general distri- bution until and if the report is printed as a Senate Document. The accompanying fact sheets should give you sufficient data, however, until reports are available upon request. As you know the report is now being reviewed by federal agencies and the governors of the basin states. Under the Flood Control Act of 1944, they have approximately until May 1, 1951, to submit their comments to the Secretary of the Interior for subsequent submission with the report to the President and the Congress.

The plan is in the fo~ of a Bureau of Reclamation Planning Report entitled "The Colorado River Storage Project and Participating Projects, Upper Colorado River Basin." The Report, which also goes to other Federal Agencies for review and comment, envisions the eventual construction by the Bureau of Reclamation of 10 dams and reservoirs with storage capacity of 48.5 million acre-feet of water and 1,622,000 kilowatts of hydroelectric cape.city and nume rous partici- pating irrigation projects.

    The Colorado River: Lifeline of the Southwest { The Headwaters The Colorado River begins in the Rocky Mountains at elevation 10,000 feet, about 60 miles northwest of Denver in Colorado. The Path Snow melts into water, flows into the river and moves downstream. In Utah, the river meets primary tributaries, the Green River and the San Juan River, before flowing into Lake Powell and beyond. Source: Bureau of Reclamation The Path In total, the Colorado River cuts through 1,450 miles of mountains, plains and deserts to Mexico and the Gulf of California. Source: George Eastman House It was almost 1,500 years ago when humans first tapped the river. Since then, the water has been claimed, reclaimed, divided and subdivided many times. The river is the life source for seven states – Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming – as well as the Republic of Mexico. River Water Uses There are many demands for Colorado River water: • Agriculture and Livestock • Municipal and Industrial • Recreation • Fish/Wildlife and Habitat • Hydroelectricity • Tribes • Mexico Source: USGS Agriculture The Colorado River provides irrigation water to about 3.5 million acres of farmland – about 80 percent of its flows. Municipal Phoenix Denver About 15 percent of Colorado River flows provide drinking and household water to more than 30 million people.
