currently irrimetee lands, the msximum ;shortage is 11.4 percent in <br />1 ^37 with a r_axi;num accumuletive shortage of 45.4 norcent for the period <br />of On new lands, th^ maximum shortage is 26.4 percent in <br />1938 with a maximum accumulative shortama of 92.8 percent for the period <br />of 1934 -1941. Since a reservoir of 1,000,000 acre -feet Capacity at <br />l' arrov.s g i 11 not insure an n dequate Tva.ter supply for a larger pro,iect <br />than an 825,000 acre -foot reservoir, it is concluded that a reservoir <br />of appro,-Jirately 825,000 acre -feet capacity will achieve maximum uti li- <br />,,ration of the availnble surface water sunnly. <br />Conclusion from nnera.tion Stttdin <br />To insure an adequate vrrtter sunnly for 230,000 acres of currently <br />4rrigatnd Irma xith increased return flows from the Colorado -Rig <br />Thimpson projiet added to historical flo•N at Kersey will require a <br />reservoir of 825,000 acre -foot capacity. If the Blue -Couth Platte <br />'ro jest is cor^nleted with transnountai.n diversions of 430,000 acre - <br />feat annually, this 825,000 acre -foot roservoir will hermit the <br />development of 30,000 acros of new land. This is also the maximum <br />size project that can be drveloned with the available .rater supply. <br />Thus, from the standpoint of insuring an adequate water su,)ply to <br />currently irrigated land and providing a reservoir that can be inte- <br />grated with probable future development, a reservoir of 825,000 acre - <br />foot capacity at Narrows will be an efficient project that will permit <br />logical development of water resources for irrigation. <br />OR <br />C <br />
