the Navajo Nation's share of the construction cost of the Navajo-Gallup Water Supply Project plus . associated conjunctive management groundwater wells; (2) the federal contributions to the Navajo Nation Water Development Trust Fund; and (3) the cost of the Joint Hydrographic Survey. Of this amount, $37.2 million for construction of wells outside the San Juan River Basin in New Mexico, but within the Navajo-Gallup Water Supply Project service area, would result in less demand for water from the San Juan River and may contribute to settlement of Navajo Nation claims in other basins. The Upper Colorado River Basin Compact apportionment to New Mexico is at least 669,000 acre-feet of consumptive use annually. Of that amount, about 58,000 acre-feet is New Mexico's share of reservoir evaporation from Colorado River Storage Project reservoirs (Flaming Gorge Reservoir, Curecanti Unit reservoirs and Lake Powell) that regulate flow for the Upper Basin's delivery at Lee Ferry under the Colorado River Compact. Authorization and completion of water projects as proposed in the Settlement Act would allow the State of New Mexico to fully utilize the minimum apportionment available for uses within New Mexico, after deduction of New Mexico's share of the Colorado River Storage Project reservoir evaporation. Under the Settlement Agreement, approximately 60 percent of the minimum apportionment to New Mexico would benefit the Navajo Nation. Because of large potential Indian claims to water, the State of New Mexico was apportioned 11.25% of the water available to the Upper Basin, after Arizona's use, to provide for Indian and non-Indian uses in New . Mexico even though the flows contributed by runoff originating in New Mexico amount to only a few percent of the total flow of the Upper Basin. Because the Upper Colorado River Basin Compact apportions consumptive uses, depletions are the primary consideration for water planning and water administration in the San Juan River Basin under the Compact. Nevertheless, it is expected that approximately 730,000 acre-feet of water would be diverted in New Mexico annually by 2040 from the flows of the San Juan River and its tributaries, . 8
