<br />Yr. Determination <br /> <br />W <br />IoQl. <br />00 <br />..... <br /> <br />Recognizing tne status of water use in tne Upper Colorado River Basin, the <br />physical availability, and institutional constraints, it is determined <br />~) through hydrologi~, investigation that sufficient water is reasonably likely <br />to be available under the provision of Section 11(a) of Public Law 87-483: <br />to fu1fill contracts that involve additional Navajo Reservoir water <br />depletions up to 94,500 acre-feet'annually. Of this amount, 3,000 <br />acre-feet annually has been reserved for use in perpetuity by the Jicarilla <br />Apache Tribe, ~9,000 acre-feet annually is available for marketing through <br />the year 2039, and an additional 22,500 acre-feet of water annually is <br />reasonably likely to be available for depletion from Navajo Reservoir in <br />perpetuity. <br /> <br /><::> <br /> <br />Extensive hydrologic data analyses, present Colorado River Storage Project <br />operating policies, and required and projected Upper Basin water <br />deliveries, support the Upper Basin depletion limit of 6.0 MAF. This 6.0 <br />MAF yield from the Upper Colorado River Basin is recognized by the Bureau <br />and the Department as an estimate which takes into account risk and <br />shortage criteria as well as providing for the minimum operational release <br />of 8.23 MAF at Lees Ferry. The 6.0 MAF figure is an estimate to be used <br />for planning purposes only and is not intended to be an interpretation of <br />the Upper Basin entitlement according to the provisions of the Colorado <br />River Compacts and other law of the river. <br /> <br />Therefore, we conclude that the projection of water uses now envisioned in <br />the Upper Basin by year 2040 can reach a 6.0 MAF depletion leve1 without <br />impairment of the Upper Basin's ability to meet its water delivery <br />obligation to the Lower Basin and the Republic of Mexico. <br /> <br />20 <br />
