3739 46 RUEDl DAM AND RESERYOIR, COLO. It was further assumed that Ihe, direct flo,,"s di,'ert.ihle uudel' the . rig-hts for the. Bluf'stoIle and I-Iavemeyer ditches would supply t.he full diversion requirement of the irrigahle lands of the d~Yelo'p!llent ,,-ithollt shol'tafTc. An aver:llre of ahout 44,800 ncre-ft-'et, of addlt.IOllal \Y~'ter would l~ave heen fivaTlahle, annnallv. Const"ruct.ion of addi- tional reservoir storage "raS not cOllsiderer] necessary in t.he Clitfs- Divide report. It was anticipated that the in'igable lauds of the area would be devoted to the production of a If a lfa, cereals, po~utoes, sugar. b~ets, pasture, and fruit. Estimates of payment cnpaclt.,y and the ll'l'lga- t.ion benetits should be. based on an economy of t.his type. Xu chunf1es in the !rellera1 physical plan fol' the. Bluestone develop. ment. would be requil:ecl for the lands to utilize water released fro~n Rncrti Reservoir. The releasps would be conveyed from the reSClTOlr by natura] cll:,ull1els of Frying-pan Cl'eek~ ROlL"ring Fork Ri,'el', and Colora.do River to the diversion points of the Hnvemeyer canal and the Bluestone ditch. During a sllustftnt.ial portioll of lleady e;very irri~ation ~eaSOll there would probably be sufficient water in tbe Colorado River to supply requirements of the Bluestone development and other existing' and potential de\'elopments in the general area. The amount. of water that, wonld be required from Huedi Reservoir fOT' the Blue~tolle lands during 10\'\ flow periods would depend on 8everall1ndetermined fac- tors, These factors lnclndc the lega.lity of diverting water under the rig:ht previously estn,blished for the HavBmeycr canal, the possibility of ut.ilizing other SOllrL'eS of water on the Bll1e~tone lands, and the efl'eet, on the ,,"ateI' supply due to other potential developments. . If t,he previously established wat.er right fol' the I-Ift\'emeyer callal were rletermined to l'ellla,in legally operative, requil'e-ll releilses from Rlledi ne~er\'oil' for t.he Blueslone lands would notnornnl1ly be greater than those necessnry to meet demands on the canal in ex~ess of 200 se(;ond-feet. If diversions could not be made under that right, Ruedi Reservoir storage wOllld be rerl1lirerl to supply at least in part the reqllirements of the la.nds unrle-r the Haycmeyer c,uml. Other potent,ial de-yelopments could conceivably either benefit. or reduce the. ,water supply fi\'ailnble to the Bluestone lands depending upon locat.lOu and type of the ot.hel' de,'eloJllllents and upon the priority of t-heir water rights with respect to any new rights required. for the Bluestone development. It is C"onsidel'ea tlu,lt. addit.ional irri. g:ation development of CaU]e Creek nnd l\Ionnt Sopris tHeftS would. in~ri::'ase late summer flows of the Colorftdo Rin>.r because. of nddi- t.iollftl retUI11 flow, thereby reducing any required releases of slorage watf'r for the nl11e~.tone lands. I rno ndditiomtl irrigation de,,'elop- mcnts were made for the- Cllttle Creek or :!\Iollnt. Sapris nrrH!', it there- fore would be necessary to supply a greater portion of the Bluestone requirements directly from Ruedi' Rescl'yoir. Summary Preliminary anulysps were made to provide. a,ll indication of how' Ruedi Reservoir could be utilized to meet irrigation requirements of the Cnttle Creek and Bluestone areaS.
