PRESENT PROPOSED ACTION In summary. thc Project (Reclamation's preferred alternativc) would store water pumped from [he Animas River in Ridges Basin ReservOir llnd would store water tlivened from the La Plata and Animas Rivers in Southern Utc Rescn'oir. The major Project features include two off-strelllll dams and reservoirs (Ridges Basin and Southern Ute Dams and Reservoirs); twO major pumping plants (Durango and Ridges Basin Pumping Plants); three major water conveyance systems (DIY Side and Southern Ute Inlet Canals and Ridaes Basin Inlet Conduit); and two diversion dams on the La Plata River (La Plata and Southern Ute DiverSion DllIll5). The total water supply developed by the Projcct would average 191,230 aere-feet annually for agricultural irrigation and municipal and industrial (M&I) uses. About 111,130 acre.foct of Project water would be delivered to 17,590 acres of AmericlII1lndian (Indian) and non-Indian land currcntly being irrigated and 48,310 acres of Indian and non-Intlian land not presently being irrigated. An annual M&I supply of 40.000 acre-fcct would bc available to non-Indian communities in Colorado ~ New Mexico. An annual supply of 40.1 00 acre-feet of M&l water would be provided to the Southern Ute Indian Tribe. the Ute MOWltain Utc Tribe, and the Navajo Nation (Nation). OTHER ALTERNATIVES CONSIDERED In addition [0 the Proposed Plan, described above. Reclamation evaluated a No Action Altcrnative and a 1980 FES Plan Alternative. Under the No Ac[ion Alternative, the Project would not be constrUcted. As a result, [enns of the Sealement Act would not be met, and the Ute Tribes would initiate either litigation or nellO[iation with other water IIsers and the United StoICS to resolve their water claims. Tri!?al economic development would be delayed. and existing non-Indian irrigallon-related uses could be scvcrely cunailcd: any independent watcr development would be subjcct to Indian Wllter rights settlement. Non-Indian agricultural water dc\.clopment and M&I water use would be subjcet to the individual efforts of the mWlicipalities and industrlcs to acquire and develop water for their use. Thcrc could be independent development of small water storage and conveyance: facilities in or adjacent to [he Project area. However, all future non.lndian water development and use could be subject to resolution of Colorado Ute Indian \ValCr rights claims, The 1980 FES PI:m, [he selccted alternative In [he 1980 FF.S. embodies the present Proposed Plan without refinements that have oceurred since [hat lime. I[ includes many of the same major features as S.2
