<br />, .- <br /> <br />DISCLAIMER <br /> <br />The Upper Colorado River Basin Compact provides that the States of Arizon <br />Colorado, New Mexico, Utah, and wyoming will share in the consumptive use <br />of water availab1e in the Upper basin in the following constant and <br />proportions: <br /> <br /> Arizona 50,000 acre-feet <br />0 Colorado 51.75 percent of the remainder <br />CJ New Mexico 11. 25 percent of the remainder <br />W <br />.s;:.. Utah 23.00 percent of the remainder <br />00 <br />-J Wyoming 14.00 percent of the remainder <br /> <br />To be conservative in making its estimate of water supply and depletions <br />the Upper Basin, the Department of Interior has assumed that the riverflo\ <br />will be 75 MAF every 10 years at Lee Ferry, plus 750,000 acre-feet annual: <br />for Mexican Treaty deliveries. This would require an average annual watel <br />delivery at Lee Ferry of 8.25 MAF. Using this assumption, the Department <br />of the Interior estimates that the long-term dependable yield of water <br />available in the Upper Basin for consumptive use by man is 6.0 MAF per <br />year. this assumption is not to be considered an interpretation of the <br />obligation of the Upper Basin States for water delivery at Lee Ferry undel <br />the Colorado River Compact, nor is it in accord with the view of the Uppel <br />Basin States. It is the position of the Upper Colorado River Commission <br />and the upper Basin States that, with the delivery at Lee Ferry of 75 MAF <br />of water in each period of 10 consecutive years, the water supply availabl <br />in the Colorado River System below Lee Ferry is sufficient to meet the <br />apportionments to the Lower Basin provided for in Article III (a) and (b) <br />of the Colorado River Compact and the entire Mexican Treaty delivery. The <br />Upper Basin States submit that the long-term dependable yield of water <br />available in the Upper Basin would be at least 6.3 MAF. <br /> <br />The values of 'State Share' and 'Remaining Water Available' which appear i <br />the depletion tables are based on the Department of the Interior's assumed <br />dependable yield of 6.0 MAF of water available for consumptive use in the <br /> <br />26 <br />
