iJOS 6- ~_ Page exprossed the view tMt the present draft of interim roport on the first phase of the Gunnison~ArkEnsas Projeot is providing for too small an flJDOunt of 'l'/9.ter for J:lLlIIicipal use in the valley, In foreca.sting the needs of munioipalities in the next fifty year's he suggested that the figure be inoreased to about 30;000 aore-feet lllld that IUI1ple capacity be provided in the pipelinec It was pointed out that such llll allooation should be ear" marked for future municipal use but made available for irri~ation until needed by the llIIl!lioipali ties, IJr, Dellllley concurred with l!r. Page., reiterating that these reqUirements should be given further oonsideration. In regard to repay-... ment aspeots of suoh an arrangement, Mr" Larson mentioned that, as in the oase of the Metropolitan Water Distriot of Salt Lake City, the munioipalities oould oontraot for payment or the ,:"later with right to lease it for irrigation use until needed by the munioipalities, at a price not greater than the cost in order to prevent speoulation. Discussion of Divertible Water (inolu<!i:nr, Twin Lakes) 7. 1lr. Powell reported that he had several meetings with engineers of the Colora.do Water Conservation Board and the Hydrology Dh1.sion, Branoh of Projeot Pl!lIlIling to arrive at final agreement on engineering aspects of l'18ter available for diversion to the potential G=ison,..Arkansas Projeot from the Fryingpan River and through the system of the Twin Lakes Reservoir and Canal COI:lpany. As a result of these oonferenoes !lIld studies it appears that the following average (1911,,1947 period) quantities of 'water are divertible to the projeot~ FIJdngpan Creek,. ,...,,58,000 aore-feet livin Lake s systen, ,., ; , ,52; 800 acre-f'eet The ostimates '\Vere based and corr'elated with operation experienoe of the Ttvin Lakes system. and on the assumption that winter l\'ater TlOUld not be diverted" Liberal allowanoes were made f'or bypass water. for 08011 on Vlater by the Salvation Ditch up to the limit of its priority, for local oonsumptive uses on. and maintenanoe of a 30 ~fs live stream in, the Fryingpon Creek: and for assumed replaoement requirements to take care of Western Slope demnnds at Grand Junotion. Mr, Beise asl::ed what the present diversions of the Twin Lo.kes system are and Hr. Berriell replied that they avera<;e 36,000 aore-feet annually, It 'Was oonoludod, thereforer that the additional neTT water that could be exported from the Colorado into the Ar~~sas Volley would amount to about 74,800 aore-feet annually (52;800 - 36,000 I 58,000 = 74,800) Vlhich is a reduction fron the original estimate of 90.000 aore.reet. !Jr. Gildersleeve indioated that he believed the estimates of di~rtible flow to be oonservative, llr. Jox stated that he had not made a detailed study of' divertible flow but felt satisfied that the estimates were based on detailed studies made by qualified engineers, He indioated that there might be a "squeeze.II on ...~"" n.t Norrie for pasture irrigation and diversion to fish ponds llessrs. Povrell and Riter pointed out that any inorease in use can be offset by pioking up 4
