<br />distributed by Statesl 8,000 in New lIexico; 2lB,OOO in Nevada; 5,649,500 in
<br />California; and 2,894,900 in Arizona.

<br />NOTE (6). From a hurried inspection of the Report, no statement was found
<br />comparing the allocations of the Colo,rado River Compact for the
<br />Lower Basin with the present and future depletions of described
<br />projects, as above outlined.
<br />
<br />.
<br />
<br />However, the Report points out that, exclurive of Gila River deple-
<br />tions, and exclusive of any allocation of water to Nexico by international
<br />agreemerrt, the PI' esent and described potential depletions of t he flow of the
<br />Colorado River in the LoW3r Basin totals 9,922,000 acre feet; and states that
<br />it is therefore evident that the projects discussed will need to be modified
<br />to conform with the available water supply; and that selection and mOdifica-
<br />tion will depend on the relative merits of each project, final allocations
<br />of water, desires of the States concerned. and results of further investiga-
<br />tions.
<br />
<br />NOTE (7)1 The Report avoids discussion of the word "surplus," as that term
<br />is used in the ColoradO River Compaot. Its treatment of the sup-
<br />ply and depletion subject suggests thatl (a) there is no surplus
<br />in the Upper Basin, whereas (b) in the LOwer Basin the supply of
<br />9,331,000 acre reet at Laguna Dam, exclusive of the Gila River,
<br />is 1,831,000 aCN feet in excess of the 7 ;500,000 allocated to the
<br />Lower Basin, not counting the additional 1,000,000 aore feet which
<br />some believe was included to cover the Gila River. Upon this ba-
<br />sis the proposed allocation to Mexico by treaty, which per Compact
<br />must first come out of surplus. would not affect the States of the
<br />Upper Basin; but v.ould come exclusively from the Lower Basin sup-
<br />plies, as the same are analyzed in the Report and largely derived
<br />from the Upper Basin.
