M25'79 Year Year Item 1990 2014 Recreatlon/Dead Pool 2100 AF 1434 AF Sedimentation 1730 AF 7395 AF Rangely 1735 AF 1735 AF Other Water Sales 8235 AF 3236 AF It Is possible that the yield from the reservoir could change If another party, such as the town of Rangely or an oil company, were to transfer a water right to the reservoir site, At this time it Is not possible to predict how the depletion pattern might change. The change would depend on the seniority of the right transferred and the conditions Imposed by the State of Colorado. Should this occur, the proposal would need to be evaluated under the requl rements of the National Environmental Pol Icy Act and Endangered Species Act. 2.2.3,4 Addition of a reservoir would affect the "finn annual yield" of the White River In the vicinity of Rangely. Finn yield is the mlnllTU11 aJT'Ount of water that could be diverted from the river on a continuous basis over the year, Without a reservoir to supplement withdrawals In times of drought, the flnn yield would be the lowest recorded flow In the driest year, 62 cfs or 44,930 AF per year (1.75m3/s or 56x106m3). This diversion would completely deplete the flow In the White River during a drought year. A flnn yield with the reservoir In place has been establ ished for maintaining a minimun bypass of 200 cfs (5.65m3/s) or the Incoming flow, whichever is less. The I ntent I on I s not to cause the flow to be 1 ess than 200 cfs (5.65m3/s) during filling. At most times the release from the reservoir will be the same as the incoming flow. See Figure 5-1, 5-2, and 5-3 for the projected effect on downstream flow due to fill ing of the reservoir. With the above assunptlon, the Incremental flnn yield with the reservoir would be 29 cfs or 21,240 AF per year (0.83 m3/s or 26x106m3).(26) The implementation of Alternative A could actually result In a depletion of 21,240 AF (26x106m3) from the White River 6 3 Instead of the actual reservoir capacity of 13,800 AF C17x10 m), 15 L, ,
