<br />fH)'457 <br /> <br />-25- <br /> <br />. <br /> <br />42. With respect to export diversions from the Colorado River system <br />above 1./3e Ferry, for use outside the natural basin in States of the Upper <br />Division, the Report shows existing exportations averaging l81,000 acre <br />feet annuallYl an allowance of 458,000 acre feet for projects now author- <br />ized or under oonstruction; and potential exportations by projects listed <br />in the report estimated at 2,l32,000 acre feet annually. E:l\Portation pro- <br />jects in and for tre benefit of Colorado are shown in the Report to involve <br />existing exportations of 102.000 acre feet, an allowance of 420.000 acre <br />feet for projects now authorized or under construction, and estimated ex- <br />portations by listed potential projects averaging 1.'2h7.COO acre feet an- <br />nually. Colorado says the existing exportation projects in Colorado, in <br />their present status of oonstruction, are diverting 135.000 acre feet an- <br />nually under normal climatic conditions; that the potential export diver- <br />sion projects are improperly desoribed in the Report; that such descrip- <br />tions as may appear in the revised final draft of the Report should be <br />prepared by or be in accordance with the most recent and feasible plans <br />of the regional directors in char ge of such investigations and project re- <br />ports; and that the estimated depletion allowances for potential exporta- <br />tion projects in ColoradO do. not adequately reflect the opportunities and <br />probabilities of such diversions, and are far below the possibilities of <br />such developments in Colorado, if questions of project feasibility and <br />economic justification be evaluated upon the same basis as that employed <br />for other competitive projects listed in the Report. <br /> <br />43. Existing exportation projects in Colorado. in their present sta- <br />tus of construction, and in an average year of normal climatic conditions, <br />are now diverting waters of the ColoradO River system. to the extent of <br />73,400 acre feet to the South Platte River basin, 58,lOO acre feet to the <br />Arkansas River basin, and 4,200 acre feet to the Rio Grande basin, or a <br />total of l35.700 acre feet annually, as shown in detail by individual pro- <br />jects in the Statement of the State of Colorado presented at the meeting <br />in Reno, Nevada, July 20, 1944. Note, from said Statement, that 51,400 <br />acre feet are being diverted by City of Denver developments. and that <br />allowances are necessary for increased future exportations by enterprises <br />heretofore constructed and now in operation, which allowances for City of <br />Denver and other projects are estimated at 132.300 acre feet annually, <br />and which with exiccing diversions will bring the total to 268,000 acre <br />feet annually. The allowance made in the Report for increased exporta- <br />tions by existing projeots is 100.000 acre feet (City of Denver). which <br />Colorado says is inadequate to cover also all other projects now operat- <br />ing. <br /> <br />p <br /> <br />. <br /> <br />J <br /> <br />. <br /> <br />44. Allowances made in the Report for future exportations of projects <br />now authorized or under construction in Colorado aggregating 420.000 acre <br />feet (Denver 100,000 and ColoradO-Big Thompson 320,000 acre feet). In <br />this category the Report should include 21,000 aore feet for the Weminuche <br />Pass Tunnel unit of the authorized San Luis Valley project (page 120 cf <br />Report) . <br /> <br />45. Opportunities for future exportations of ColoradO River water <br />for use in the San Luis Valley in Colorado inclUde the Piedra-Rio Grande <br />diversion (70,000 acre feet, described at page 120). which includes two <br />
