<br />5 <br /> <br />o <br />CJ1 <br />c.c <br />~ <br /> <br />year flows by storing in high inflow years and releasing in low inflow <br /> <br />years. <br />An example of a moderate size reservoir on the White River, with a <br />capacity of 120,000 acre-feet located just below Meeker, Colorado, is used <br />to illustrate this technique. This hypothetical reservoir stores spring <br /> <br />runoff for release in lower flow sUlllJJ\er months and in winter months. <br /> <br />Limited year to year regulation is used only to augment extreme winter <br /> <br /> <br />flow shortages, The amount of this year to year regulation is too small <br /> <br /> <br />to be affected by weather cycle correlation, Thus, the assumptions of <br /> <br /> <br />this analytic technique are preserved in this example, <br /> <br /> <br />The following estimates of water consumption by an oil shale industry <br /> <br />in the year 2000 in the Colorado and Utah portions of the White River <br /> <br />basin are taken from the DOE Accelerated Syn-Fuels scenario of the on-going <br /> <br /> <br />Upper Colorado River Region l3(a) Assessment. The oil shale industry's <br /> <br />water consumption is assumed to be at the 50th percentile from the possible <br /> <br />range of literature values for consumption per barrel of oil produced. <br /> <br />This amounts to 18,000 acre-feet per month of White River inflows (12,000 <br /> <br />acre-feet in Colorado and 6,000 acre-feet in Utah). All ground water in <br /> <br />the White River Basin is assumed to enter the surface flows of the river <br /> <br />at some point, Thus, use of ground water in an oil shale process is <br />assumed to have the same consumptive effect as using surface waters. <br />By 2000, the total monthly consumptive uses and losses (CL~) of <br />all kinds,pIus-TJie newassumed-oiIshale uses including regulation-losses - <br />(seepage andevaporation};--will De assumed as follows in the R, S, and IV <br /> <br />seasons: <br />
