<br />~8. Potential projects listed in the Report are estimated at ,,02~,OOO
<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 that future
<br />increased water utilization will oco~ largely in the Upper Basin. That
<br />showing results: from oombining the existing depletions with future deple-
<br />tions of projeots and lands for which "allowances" are made in the Report.
<br />A more aoourate pioture would be presented if such future "allowanoes"
<br />were oombined with similar future depletions of potential projeots. On
<br />that basilF the future iroreased utilization of ~ters of the Colorado Ri-
<br />ver system, outlined in the Report, will 8I!l0unt to ",14,000 aore-feet an-
<br />nually in the Upper Basin, and 6,595,500 aore feet annually in the Lower
<br />Basin. Together with existing depletions, the total depletions will be-
<br />ooma 7,64~,OOO aore feet in the Upper BaSin, and 11,092,600 aore feet in
<br />the Lower Basin, per estimates of the Bureau of Reclamation, as fOllows,

<br />Considering the quantities of water heretofore apportioned tp
<br />eac.h of the basins by the Compaot (7,500,000 to Upper Basin and 8,500,000
<br />to Lower Basin) it is apperent that the potential projeots listed in the
<br />Report for the Upper Basin OM be oonstruoted with assuranoe that _ter
<br />supplies, within the provisions of the Compact, will be available to all
<br />(or substantially all) suoh projects, whereas in the Lower Basin a con-
<br />siderable portion of the listed projeots could have no suoh assuranoe at
<br />the present time. Instead, the list of potential Lower Basin projeo,ts
<br />must be treated as a list of development possibilities from whioh seleo-
<br />_ tions must be made, or be considered as a list of alternat,ive possibili-
<br />ties in lieu of those ,future inoreased depletions, or SomB of them, for
<br />whioh allowanoes are lMde in the Report. Colorado BIlYs that the poten-
<br />tial projeots listed in the Report for the Upper ~asin should be expand-
<br />ed so as to refleot allthe ,opportunities for developlllllnt in ,the Upper
