The Durango Diversion Plan would Reservoir as the main storage feature water would be pumped into the Ridges Pumping Plant just south of Durango. Durango would be supplied from Ridges utilize the Ridges Basin Dam and on the project. Animas River Basin Reservoir by the Durango Municipal and industrial water for Basin Reservoir. The Ridges Basin Pumping Plant and Ridges Basin Canal would convey stored water from the reservoir to the La Plata River drainage, where it would be utilized for irrigation and for resource development on the Ute Mountain Ute Indian Reservation. Hay Gulch Reservoir would provide terminal storage for the Dryside area. The La Plata Diversion Dam and La Plata Canal would divert additional water to Hay Gulch from the La Plata River. Power would be generated at the potential Animas Power- plant and utilized along with supplemental power purchases from CRSP to provide power for project pumping. Municipal and industrial water for Farmington and Aztec, New Mexico would be supplied by direct flow from the Animas River. Releases from Ridges Basin Reservoir would be made to the Animas River when the river flow could not meet the demand for Farmington and Aztec. The Lower Animas Diversion Canal, located below Durango, would divert water by gravity to the Southern Ute Reservoir. This water would be used for industrial purposes on the Southern Ute Indian Reservation and for irrigation in New Mexico. Southern Ute Indian lands near the reservoir would be irrigated with water from the Lower Animas Canal. Sprinkler irrigation systems are planned for all project areas except the La Plata, New Mexico area and La Plata, Colorado area above the Ridges Basin Canal which would use the existing open ditch system. The lateral systems would provide sprinkler pressure at the farm turn- outs. Pumping plants would be used to provide this pressure where the ground slope is insufficient to pressurize the pipeline. Project drainage would be provided. Fisheries would be created in the inactive space in project reser- voirs and recreational facilities would be provided at each reservoir. A minimum stream bypass of 100 second-feet would be provided below both the Durango Pumping Plant and the Lower Animas Diversion Canal except when the natural flow drops below 100 second-feet. Project costs including operation and maintenance have been esti- mated for comparative purposes only. No detailed engineering sizing and costing have been done on any facilities described.' A plan.on which to base feasibility costing will be selected by an Advisory Team composed of representatives from Colorado and New Mexico. Comparative estimates indicate the project could cost about $250 million and develop about 233,000 acre-feet of water. An allocation of water supply will be determined when a plan is selected. -2-
