3728 RUEDI DAM AND RESERVOIR, COLO. 35 in the critical year oT 19:]4. In years oT more than ample, "'ateI' supply, when t.he mandatorv and lll11llicipn 1 and industrial water releases would not result. in ~l\. reseI'yoir tlrn'Hlmnl to 67,000 acre.feet, some :-Hldit.ional winter releases would be made in a. manner to achieye uni~ form total outflow. Such winter releases might pro\'ide some down~ stream benefits but no enlluation has been mnde. The cle[)leted reservoir inflow n.H'.ral.TinlT 109.200 acre-feet. u.nnually ~ ~ . would be increased to 125,700 a.cre-feet, or 15 percent, had the opera~ tiOIl stndy coyered the long-term periocl-1911 to 1957. Jlowever, the results of the monthly analysis for the critic:11 years lying wit.hin the shorter August 19:?9-.Tu]y 1948 period of study wou],] not change. The entire water yield of Ruedi Reservoir oT 70,000 acre-feet would be demanded in a yeaT such as 1934 to meet 2014 municipal and indus- trial water requirements.

Production oT oil !lnd related byproduets Trom the \'ast, 011 shale deposits in the area is undoubtedly the lar'gest potential il"lClllstriu.1 de- velopment that is likely to OCCllr in the m~lU' future. Sonll;~ of the largest and richest oil shale deposits ill the world are located along the Colorado River near the towns oT Rifle, Grand Valle}, and De Beql1e. Requirements for addit.ional municipal and industrial \rater as esti. mated in this report l.\.1'e lmsell on a. logi(~al a.nd orderly deve.lopment of all oil shale indust.ry. Eyen partial development of the oil shale potent.ialities would require significant quantitIes of \rater for indus. trial processing and for related service indust.ries and residential areas. The firm of Cltllleron & .Tones, Inc., engineers-consultants, was l'et,uined by the State of Colorado to make a study of w<lter require- ments of the potenti:tl oil shf\le. indust.ry and relnted developments. The study was sUllllllnrizeu in n. report. dated .J lily HILl!), fL copy of which is appended to this report. This diseussion summarizes data presented in the Cameron &:. .J ones report and otlier data obtained Trom studies prepared by agencies oT the State of Colorado. The general area ulso contains a weulth of other resources that coul(l materially contribute to the growt.h of populntion cent.ers and inerense demands for municipal and industrial water. These resonrce.'i inell1de mineral deposits~ timber rese.rves, gas and petroleum reserves, agricultural potentialities, and recreational possibilities. No attempt is made in this report. t.o eVllhwte the additional requirement.s for municipal and indu~t.rifll water t.hn,t eould result fl'OHl future. f1evel- opment of industry based on these resources.
