<br />1 <br />i <br /> <br />fJ01~53 <br /> <br />-21- <br /> <br />for future expansion which with existin~ depleticns in the Lower Basin will <br />exceed 8.500,000 aore-feet annually; and objects to the implication that <br />additional potential projects may be oonstructed in the Lower Basin with- <br />out suoh future proJects bein~ considered as alternative possibilities in <br />lieu of the said allowances for future depleticns of existing projects. <br /> <br />. <br /> <br />38. Potential projects listed in the Report are estimated at 5.023.000 <br />acre feet of annual depletion in the Upper Basin, and at 2,330,300 acre <br />feet in the Lower Basin. Thus the implication of the Report is thnt future <br />increased water utilization will occur lar~ely in the Upper Basin. That <br />showing results froLl combining the existing depletions with future deple- <br />tions of projects and lands for which "allowances" are made in the Report. <br />A more accure.te picture would be presented if such future "allowanoes" <br />were combined with similar future depletions of potential projects. On <br />that basis the future increased utilization of waters of the Colorado Ri- <br />ver system, outlined in the Report, will amount to 5 ,514,000 acre-feet an- <br />nually in the Upper Basin. and 6,595.500 acre feet annually in the Lower <br />Basin. Together with existing depletions, the total depletions will be- <br />come 7 ,643 .000 acre feet in the Upper Basin. and 11.092.600 acre feet in <br />the Lower Basin, per estimates of the Bureau of Reclamation, as follows. <br /> <br /> Dep let ions of Colorado R.i. vel' System <br /> per Report <br /> Upper Lower Total <br /> Basin Basin Depletions <br />Allowances per Report 491,000 4,265,200 4.756,200 <br />Potential project Depletions 5.023,000 2,330,300 7.353,300 <br />Combined Future Increase 5.514.000 6.595.500 12,109.500 <br />Existin~ Depletions 2.12;1,000 4,497,100 6.626 .100 <br />Total Depletions 7 ..643.000 11,092.600 38.735.600 <br /> <br />Considering the quantities of water heretofore 'apportioned to <br />each of the basins 1;y the Compa0t (7.500.000 to UpF'lr Basin and 8.500,000 <br />to Lower Basin) it iQ apparent t hat the potential projects listed in the <br />Repcrt for the UpF'lr Basin can be constructed with assurance that water <br />supplies, within the J?rovisions of the Ccmpact, will be available to a,U <br />(or substantiaUy all) such projeots, whereas in the LoI'Pr Basin a con.. <br />siderabl", portion of the listed projects oould have no suoh assuranoe at <br />the present time. Instead, the list of potential Lower Basin prpjeots <br />must be treated as e. list of development possibilities from whioh selec- <br />tions must be made, or be oonsidered as a list of alternative possibili- <br />ties in lieu of those future increased depletions. or some of them,i'br <br />which allowanoes are made in the aeport. Colorado says that the poten- <br />tial projects listed in the Report for the Upper Basin should be expand- <br />ed so as to reflect all the opportunities for development in the Upper <br />
