<br />"As to where Arizona uses its water is a matter which is entirely <br />under the control of Arizona. So that all we can do is to make assump- <br />tions as between certain limits. That is all that the Bureau of Recla- <br />mation can do. <br />"One assumption was that Arizona would choose to use in central <br />Arizona the greatest pracUcable amount of main-stream water. <br />"The CHAIRMAN. Hov/ was it to get up there? Was it to be pumped? <br />"Mr. TIPTON. H could be brought in in several ways, Senator. <br />"The CHAIRMAN. No; you started to say something about the Gila. <br />River. <br />"Mr. TIPTON. That would require pumping there. That water <br />would not be applied to cenlral Arizona, Senator; that would be applied <br />to the lands nearer the mouth of the Gila. The Gila project is near the <br />mouth of the Gila and central Arizona, as here used, is the area around <br />Phoenix. Water for that area could be pumped from Parker Dam, shown <br />on the map, and carried Lhrough a long canal system. Water could be <br />diverted by gravity from a proposed reservoir on the stream, the dam <br />of which would be immedialely above the backwater of Lake Mead. <br />Water could be diverted from that reservoir by gravity through a long <br />tunnel and would enter the same canal to supply central Arizona that <br />would be used if the 'Hater were pumped from Parker Dam or Lake Havasu, <br />which is the reservoir created by Parker Dam. Water could be diverted <br />to centra I Arizona from Marble Gorge Reservoir, the site of which is <br />above the Grand Cayon (sic), through a long tunnel, without the use <br />of any canals whatsoever. The tunnol would discharge into one of the <br />main tributaries of the Sate River which would carry the water down to <br />the present system of canals that serve the Salt River Valley. <br />* * * <br /> <br />"One assumption--gelUng back to Senator Downey's question-- <br />which envisioned the uso by Arizona of the major portion of its main <br />stream-Wa:terln central ArIzona, assumed only80, 000 acres irrigated <br />in the Gila project. That is this lower project near the mouth of the <br />Gila. <br />"Senator MURDOCK. Y'/hen you mention the Gila project, is it <br />not a fact that the water thal should be used on the Gila project is <br />not water from the Gila River, but from the main stream of the Colorado? <br />"Mr. TIPTON. Tha'l is correct sir. We are dealing with the same <br />block of water and we are asking outselves, Will it be used on the Gila <br />project or will it be used in central Arizona? In this particular assumption <br />we are saying to ourselves that there will be only 80,000 acres irrigated <br />by the Gila project, which would require a diversion of 480,000 acre-feet. <br />We are assuming under tha't condition that ill the Mojave Valley, which <br />is partly in Arizona, there would be no water used. That is a valley <br />along the main stream. The potential irrigation there is very nominal, <br />anyway. We are also assuming that on the ParJ~er Indian project, which <br /> <br />-17- <br />
