<br />\..3\.1 <br /> <br />values such as are employed in the Lower Basin and which more nearly represent <br />the normal or usual conditj_ons to be expected in the future; and second, to <br />provide for uniform treatment of both basins with respect to allowances for <br />future increases beyond present conditions, and with respect to the inclusion <br />and exclusion of areas and their depletions outside the boundaries of the <br />natural basins. <br /> <br />It may here be noted that (using figures above cited), if and when the <br />projects under construction and authorized in the Upper Basin come into opera- <br />tion, the Upper Basin "depletions" will average 2,620,000 acre feet annually, <br />which is 4,880,000 acre feet less than the 7,500,000 acre feet per annum <br />apportioned by Far. (a) of Art. III of the Colorado River Compact for "exclusive <br />beneficial consumptive use" in the Upper Basin; and, if and when the irrigable <br />lands of existing enterprises in the Lower Basin come under irrigation, the <br />"depletions" will average 8,762,300 acre feet annually, which is 262,300 acre <br />feet more than the 8,500,000 acre feet apportioned by Par. (a) and (b) of <br />Art. III of the Compact for "beneficial consumptive use" in the Lower Basin. <br /> <br />9. DISCtJSSION OF "PRESENT" DEPLETIONS. <br /> <br />The "allowance" made by the Bureau of Reclamation, in the amount of <br />4,265,000 acre feet (measured as annual depletions) for the future irrigation <br />of 579,000 acres of so-called "irrigable" land in the Boulder division, seems <br />to be an allowance, more or less arbitrarily made, of such excessive magnitude <br />(depleti on rate e'lui valent to about 7.4 acre feet per acre) as to raise a <br />question whether or not the entire amount can "reasonably be applied to <br />domestic and agricultural uses"; as required by Par. (e) of Art. III of the <br />Colorado River Compact. <br /> <br />(15) <br />
