PROJECT PLAN . A plan for the Colorado River Storage project and an initial group of participating projects has been formulated by the Bureau of Reclamation in cooperation with other Federal agencies and with the States of the Upper Colorado River Basin. The project report prepared in 1950 and a supplemental report prepared in 1953 were printed as House Document No. 364, 83d Congress, 2d Session. Reports on the participating projects in the initial group, supple- mental to the 1950 report, were also completed in 1950 and 1951. Since its introduction in the 1950 report, the project plan has been subject to modifi- cations as shown in the 1953 supplement, in the authorizing act, and in definite plan studies. Colorado River Storage Project The various dams and reservoirs of the Colorado River Storage project will regulate the flow of the river, thus permitting an expanSion of irrigation and other water use in the upper basin within the limits of the Colorado River Compact. In most instances powerplants and switchyards will be installed at the dams and transmission lines will be provided to transmit the power to load centers. Facilities will be provided as appropriate for recreation and to mitigate losses of, and improve conditions for, the pro- pagation of fish and wildlife. Minor flood control and other benefits, largely unevaluated at present, are anticipated from the storage project. . The Colorado River Storage project as outlined 1n the 1950 report included ten storage units. Four of these were authorized for construction by the act of April 11, 1956. It is anticipated that additional units will be authorized as they become needed. The four authorized units are the Glen Canyon, Flaming Gorge, Navajo, and Curecanti. Together they will provide about 34,570,000 acre-feet of reservoir capacity and about 1,108,000 kilowatts of installed generating capacity. More than three-fourths of both capacities will be provided by the Glen Canyon unit alone. Participating Projects . Participating projects are those which will consume water of the Upper Colorado River system for irrigation and other purposes and which will require assistance from power revenues of the storage project in the repay- ment of irrigation costs. An initial group of 11 participating projects was authorized by the act of April 11, 1956. These include the Paonia, Smith Fork, Florida, and Silt projects in Colorado; the Pine River project exten- sion in Colorado and New Mexico; the Hammond project in New Mexico; the Central Utah project (initial phase) and Emery County project in Utah; and the Seedskadee, La Barge, and Lyman projects in Wyoming. The Pine River project extension has been excluded from the scheduled program of development. The remaining projects combined would provide water for a total of about 346,460 acres, including about 115,440 acres of full service land and about 231,020 acres of supplemental service land. -1-
