<br />42. With respeot to export diversions from the Colorado River system
<br />above Lee Ferry, for use outside the natura~ basin in States of the Upper
<br />Division, the Report show~ existing exportations averaging 181,000 aore
<br />feet annually; an allowanoe of 458,000 aore f,et for projeots now author~
<br />ized or under oonstruotion; and potential exportations by pr~eots listed
<br />in the report estimated at 2,132,000 aore feet annually. Exportation pro-
<br />jeots in and for the benefit of Colorado are shown in the Report to involve
<br />existing exportations of 102,000 aore feet, an allowanoe of 420,000 aore
<br />feet for projeots now authorized or underoonstruotion, and estimated ex-
<br />portations by listed potential projeots averaging 1,267,000 aore feet an-
<br />nually. Colorado says the existing exportation projeots in Colore.do, in
<br />their present status of oonstruotion, are diverting 1~5,OOO aore feet an-
<br />nually under normal olimatio oonditions; that the potential export diver-
<br />sion projeot~ are improperly desoribed in the Report; that suoh desorip-
<br />tions as- may appear in the revised final draft of the Report shoulp, be
<br />prepe.red by or be in aooordanoe with the most reoent and feasible plans
<br />of the regional direotors in charge of suoh investigations and projeot re-
<br />ports; and the.t the estimated depletion e,llowanoee for potential exporta-
<br />tion projeots in Colorado do not adequately refleot the opportunities and
<br />probabilities of suoh diversions, and are far below' the possibilities of
<br />suoh developments in Colorado, if questions of projeot feasibility and
<br />eoonomio justifioation be evaluated upon the, same basis as that employed
<br />for other oompetitive projeots listed in the Report.
<br />
<br />43. Existing exportation projeots in Colorado, in their present stll-
<br />tUB of oonstruotion, and in an average year of normal climat~o oonditions,
<br />are now diverting waters of the Colorado River system, to the extent of
<br />- 73,400 aore fee~ to the South Platte River basin, 58,100 aore feet to the
<br />Arkansas River basin, and 4,200 aore feet to the ,Rio Grande basin, or a
<br />total of 135,700 aore feet annually, as shown in detail by individual pro-
<br />jeots 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 neoessary for inoreued future exportations by enterprises
<br />heretofore oonstruoted-and now in operation, whioh allowanoes; for City of
<br />Denver and other projects are estimated at 1~2,~0 aore feet annually,
<br />and whioh with existing diversions "ill bring the tota~to, 268,000 acre
<br />feet annually. The allowanoe made in the Report for inoreased exporta-
<br />tions by existing projeots is 100,000 aore feet (City of Denver), whioh
<br />, Colorado says is; inadeqUate to oover also all other proj eots: now operat-
<br />ing.
<br />
<br />44. AllowanoellJ made in the Report for fut~e exportations of projects
<br />now authorized or under oonstruction in Colorado aggregating 420,000 acre
<br />feet (Denver 100,000 and Colorado-Big Thompson ~20,OOO acre feet). In
<br />this oategory the Report should inolude 21,000 aore feet for the Weminuche
<br />Pass Tunnel unit of the authorized San Luis Valley projeot (page 120 of
<br />Report) .
<br />
<br />45. Opportunities for future exportations of Colorado River water
<br />for use in the San Luis Valley in ColoradO inolude the Piedra-Rio Grande
<br />diversion (70,000 acre feet, described at page 120), whioh inoludes two
