<br />inlet conduit (all designed to pump and store water from the Animas River); and the NNMP to transport <br />treated municipal water to the Shiprock area, New Mexico. Consumptive use of water from the structural <br />portion of the project would be restricted to M&I uses only and would be allocated as shown in Table <br />ES-l. <br /> <br />Under this allocation, the Colorado Ute Tribes would still be approximately 13,000 af short of the total <br />quantity of depletion recognized in the Settlement Agreement. Therefore, the non-structural component <br />of the project would establish a $40 million water acquisition fund which the Colorado Ute Tribes could <br />use on a discretionary basis to purchase land to satisfY non-structural water rights (approximately 13,000 <br />afY). To provide flexibility in the use of the fund, authorization from the US Department oflnterior to <br />the Colorado Ute Tribes would allow some or all of the funds to be redirected for on-farm development, <br />water delivery infrastructure, or for water-related economic development activities. <br /> <br />The primary source of the water for the structural portion of Refined Alternative 4 is the Animas River. <br />The water supply for the non-structural component would include the Pine, Florida, Animas, La Plata, <br />Mancos and Dolores Rivers and McElmo Creek. The supply could be developed from existing uses <br />within each basin, with the associated historic shortages, so that no additional water would be needed to <br />meet the demands of the non-structural components. <br /> <br />For Refined Alternative 4, it is estimated that the purchase of about 10,300 acres of irrigated land, <br />distributed in four river basins, could be necessary to obtain the 13,000 afY of depletion described as part <br />of the water acquisition fund. The acreage could be distributed among the four basins approximately in <br />this manner: <br /> <br />Q Pine River Basin - Purchase 2,300 acres of land and leave the water on the land. <br /> <br />Q La Plata River Basin - Purchase 2,300 acres of land and leave the water on the land. <br /> <br />Q AnimasIFlorida River Basins - Purchase 2,300 acres ofland and leave the water on the land. <br /> <br />Q Mancos River Basin - Purchase 3,300 acres of land and leave water on the land. <br /> <br />Refined Alternative 6 <br /> <br />Refmed Alternative 6 proposes that water rights under the Settlement Act be obtained through <br />(I) augmentation and the coordinated operation of existing federal projects in the area proximal to the <br />Colorado Ute Tribal reservations; and (2) purchase of water rights on irrigated agricultural lands; or (3) a <br />combination of both. Other elements of Refined Alternative 6 include the NNMP and measures to avoid <br />impacting wetlands as a result of purchases of water and transferring it to M&l use. Refined Alternative <br />6 has been modified to the equivalency of the depletion amounts in Refined Alternative 4 in order to <br />analyze both alternatives on a commensurate or equivalent basis. As with Refined Alternative 4, Refined <br />Alternative 6 also consists of two components: <br /> <br />Q One component would be equivalent to the structural component of Refined Alternative 4 by <br />developing up to 57,100 afY of depletions in the San Juan River Basin to serve essentially the <br />same M&I needs as would be served by Refined Alternative 4. <br /> <br />Q A second component for Refined Alternative 6 was developed under the assumption that water <br />could be acquired to develop an equal amount of depletions of 13,000 afY and in a manner <br />similar to Refined Alternative 4 by purchasing agricultural lands and associated water rights. <br /> <br />ES-8 <br />
