5 <br /> 1 . <br /> 750,000 acre-feet annually toward Mexican Treaty deliveries. This would require <br /> an average annual water delivery at Lee Ferry of 8.25 MAF acre-feet. This <br /> • assumption is not to be considered as an interpretation of the Upper Basin obli- <br /> gation for water delivery at Lee Ferry under the Colorado River Compact. It <br /> represents, rather, a practical and conservative approach for the purposes of <br /> the present determination required by section 11(a), P. L. 87-483. <br /> Throughout the hydrologic investigation and as demonstrated in the attached <br /> tables, present Colorado River Storage Project (CRSP) operating policy along <br /> with required Upper Basin water deliveries combine to form the underlying <br /> assumptions that are integral to a hydrologic determination of water availabi- <br /> lity from Navajo Reservoir and the Upper Colorado River Basin for use in New <br /> Mexico. <br /> An estimate of projected water depletions for Bureau of Reclamation projects, <br /> together with non-Federal projects indicates that total depletions in the Upper <br /> Basin will not reach 5.8 MAF until some time after year 2030 and very likely not <br /> until 2040. The table of "Projected Water Supply and Depletions, Upper Colorado <br /> River Basin" dated August 1982, which is appended to this memorandum shows the <br /> projected timing for development of the water apportioned to each of the Upper <br /> Basin States within this 5.8 MAF limit: Arizona, 50,000 acre-feet; Colorado, <br /> 2,976,000 acre-feet; New Mexico, 647,000 acre-feet; Utah 1,322,000 acre-feet; <br /> Wyoming, 805,000 acre-feet. The Upper Basin States have reviewed this table and <br /> although they do not necessarily agree, they have chosen not to object. The <br /> State of Wyoming has said that they reserve the right to submit a formal objec- <br /> tion. <br /> • <br />
