<br />to paragraphs (2), (3), and (4) of subsection (a) and shall submit
<br />feasibility reports on such projects and programs. Said recom-
<br />mendation and feasibility reports shall include projects designed
<br />to provide water of an adequate quality for the Lower Colorado
<br />River Basin to assist in meeting that basin's long-range needs
<br />and, in any event, sufficient to meet deficiencies between the
<br />quantities required to supply water for the annual consumptive
<br />use of two million eight hundred thousand acre-feet in Arizona,
<br />four million four hnndred thousand acrecfeet in California, and
<br />three hundred thousand acre-feet in Nevada and the quantities
<br />available in the main stream of the Colorado River for such
<br />uses as determined by the Secretary,
<br />SEC. 104. In order to initiate the Lower Colorado River Basin
<br />project, herein referred to as the "project", and to further the com-
<br />prehensive development ot.the water resources of the Lower Colorado
<br />River Basin the Secretary shall-
<br />(a) construct, operate, and maintain the main stream reservoir
<br />unit consisting of the Bridge Canyon and Marble Canyon
<br />projects, including dams, reservoirs, powerplants, transmission
<br />facilities, and appurtenant works, and the Coconino and Paria
<br />River silt-detention reservoirs: Prom:ded, That Bridge Canyon
<br />Dam shall be constructed so as to impound water a.t a normal
<br />surface elevation of one thousand eight hundred and sixty-six
<br />feet above mean sea level and that Marble Canyon Dam shall
<br />be constructed so as to impound water at a normal surface
<br />elevation of three thousand one hundred and forty feet above
<br />mean sea level. The Congress hereby declares that the construc-
<br />tion of the Bridge Canyon Dam herein authorized is consistent
<br />with the Act of February 26,1919 (40 Stat. 1175);
<br />(b) construct, operate, and maintain the central Arizona unit
<br />consisting of the following principal works: (1) a system of main
<br />conduits and canals, including a main canal and pumping plants
<br />(Granite Reef aqueduct and pumping plants) for diverting and
<br />carrying Colorado River water from Lake Havasu to Orme Dam
<br />(McDowell Dam) on the Salt River above Granite Reef diversion
<br />dam; (2) Orme Dam (McDowell Dam) Reservoir, and power
<br />pumping plant; (3) Buttes Dam and Reservoir; (4) Hooker Dam
<br />and Reservoir; (5) Charleston Dam and Reservoir; (6) Tucson
<br />aqueducts and pumping plants; (7) Salt-Gila aqueduct; (8) canals,
<br />powerplants, and electrical transmission faCilities; (9) related
<br />water distribution and drainage works; and (10) appurtenant
<br />works: Provided, That for a period of twenty-five years from
<br />the effective date of this Act, or until such time as there shall
<br />have been constructed such. project or projects for supplying
<br />water in quantities at least sufficient. to avoid the deficiencies of
<br />main stream Colorado River water hereafter described, which-
<br />ever first occurs, in any year in which, as determined by the
<br />Secretary, there will be insufficient main stream Colorado River
<br />water to satisfy the consumptive uses of two million eight hun-
<br />dred thousand, four million four hundred thousand, and three
<br />hundred thousand acre-feet in Arizona, California, and Nevada,
