OCl3152 ". CRAfTER I PlANS OF DEVELOFMENT 285 feet above the pumps to the Gallegos canal, from which 29,370 acres would be irrigated. In the other pipe, with a capacity of 526 second- feet, water would be raised 406 feet above the pumps to the Bisti Canal from which the remaining 25,870 acres of project land would be irrigated. A lateral system to distribute water to all project lands would be required. The same acreage as in Plan D-l is expected to require drainage by artificial means. Plan E-l .. Plan E-l would irrigate substantially the same 67,700 acres as would be served by Plan D-l. The principal difference in the two plans is in the ineans of conveyance of water from the Navajo Reservoir to the land. Under Plan E-l the Shiprock Main Canal planned for the 100,000- acre Shiprock project alone would be enlarged to a capacity of 2,630 second-feet to convey South San Juan water from Navajo Dam to a pumping plant,a distance of 38 miles. Approximately 2,270 acres below the main canal near the mouth of Largo and Munoz Canyons, on Pauline Me se, and in the Gallegos Basin would be irrigated by gravity flow and the remain- ing 65,430 acres would be served with water pumped from the main canal by electric-motor-driven pumps. Pauline Mesa lands shown on the map as being above the Shiprock Main Canal would not be irrigated. The first pumping plant would be located at the entrance to Kutz tunnel (under New Mexico Highway No. 44). It would lift 1,329 second- feet of water 295 feet to the Gallegos Canal at an elevation of 6,000 feet. The. 579 second-feet of the water delivered to this canal would be used to. irrigate 28,490 acres. The rem9.ining 750 second-feet of water would flow in the canal 20 miles to a second pumping plant where it would be lifted 135 feet to the Bisti Canal that would extend in two direotions from the pump and would serve 36,940 acres of project land. l<lith the Shiprock Main Canal diverting from the Navajo Reservoir 268 feet lower than the Main Gravity Ce.ne.l in Plan D-l, less dead stor- age capacity in the reservoir would be required. Under Plan E-l a total Navajo Reservoir capacity of 964,000 acre-feet would be required for flow regulation and sediment deposition. An active capacity of 740,000 acre-feet and a 212,000 acre-foot reservation for sediment stor- age would be above the reservoir outlet at elevation 5,779 and 12 ,000 acre-feet of capacity would be below the outlet. A period of 100 years would elapse before sediment would begin to encroach on the portion of the active capacity required for irrigation storage. A lateral and drainage system as described in Plan D-l would be required to serve the project lands. - 9
