<br />, <br /> <br />1.\.?>'?J <br /> <br />water supply available to the upper basin, so long as the apportio~ent <br />to the upper basin by Article III(a) of-the Compact is not exceeded. <br />If it should be determined at some future date that the upper basin <br />delivery obligation at Lee Ferry includes the maximum delivery of water <br />for the Mexican Treaty obligation in any given year (750,000 acre-feet <br />pursuant to Article III (c) of the Colorado River Compact), the alloca- <br />tion to New Mexico would be reduced accordingly by 84,000 acre-feet <br />in such year (11.25 percent of 750,000 acre-feet). The results of the <br />worst possible interpretation of the Mexican Treaty burden are contained <br />in the hydrologic analysis dated November 26, 1963, and approved by the <br />Secretary December 5, 1963, previously referred to in this statement and <br />attached hereto, and in Table I attached hereto. <br /> <br />Presently existing and authorized projects for the State are estimated <br />to have a potential deplection of about 646,000 acre-feet of New Mexico's <br />entitlement in the Colorado River. Any use in New Mexico beyond the <br />State's permanent compact entitlement, although allowed by the Upper <br />Colorado River Basin Compact, must be limited in time so that the pro- <br />posed temporary use does not interfere with compact deliveries at Lee <br />Ferry and with permanent uses in other states within the upper basin. <br /> <br />An up-to-date survey of projected water use requirements for Reclamation <br />irrigation projects and both Federal and non-Federal projects being <br />planned for the utilization of water for M&I purposes, including energy- <br />related industries~ indicates that total water use in the upper basin <br />will not -iikely "r'ea~h -6,550-;000 ac-re-feet pe-r year until after year <br />2005 when the M&I contracts from Navajo Reservoir terminate. Table I, <br />attached shows the projected water requirements within New Mexico as <br />well as ~ithin the total upper basin at the end of each decade through <br />year 2000 and in year 2030. For the purpose of ~llustrating the <br />maximum possible adverse effect on the upper bas~n water supply by the <br />Mexican Treaty, Table I also indicates the maximum potential reduction <br />of upper basin supply which could be occasioned by a Mexican Treaty <br />deficiency (shown as 5.8 MAF level). <br /> <br />T~~!:. il"plL...atisfl8 af the. a'ea. z. anal) 3i3 ClEf:. t:1Et t 8~~ ::hE 1aaia af the <br /> <br />THOS t re.eeat pregram aRB. 131aaning a8~~m.eflt3, pll1.3 '-' tLeY L.\~n <br /> <br />plal...e.a. or ,3,J.l.Stlll.d .,atLl? d3~ d<:ye16fJfi.~flt iI. ~R<: Upt'e.r Col-&r-ade--R:-:i=-veF <br /> <br />4 <br />
