j/j . . OD3153 CHAPrER I PLANS OF DEVELOPMEN'l' Plan E-2 The same South San Juan project area would be served under this plan as in Plan E-l. The Shiprock Main Canal planned for the 113,900- acre Shiprock project alone would be enlarged to a capacity of 2,950 second-feet to convey water for both projects as in Plant E-l. The first electric-motor-driven pump would lift 1,329 second-feet of water 299 feet to the Gallegos Canal, and part of the water would be used to irrigate 28,490 acres under that canal. The second pumping plant would lift 750 second-feet of water for the remaining 36,940 acres the same 135 feet as in Plan E-l to the Bisti Canal. With the joint Shiprock Main Canal diverting from the Navajo Reser.. voir 245 feet lower than the canal in Plan D-2, less dead storage capac.. ity in the reservoir would be required. A total reservoir capacity of 1,249,000 acre-feet would be required, of which 1,025,000 acre-feet would be active capacity, 11,000 acre-feet would be dead storage, and 213,000 acre-feet would meet silt storage requirements for 100 years. The same lateral and drainage system would be required as in Plan D-l. Plan E-3 Under this plan 57,000 acres of land would be irrigated in the South San Juan project area, including 19,520 acres in the Navajo Indian Reservation but outside the Shiprock project area. The same lands would be irrigated as in Plans E-l and E-2 except that the Bisti Canal would not be extended to 10,700 acres in the southern part of the area near Bist i Wash. The Shiprock Main Canal planned for the 121,700-acre Ship- rock project alone would be enlarged to a capacity of 2,900 second-feet to convey water for both projects as in Plans E-l and E-2.. The pumps would be driven by electric motors. The first pump, located in the same place as in Plans E-l and E-2, would lift all South San Juan project water at that point 296 feet to the Gallegos Canal which would head at an eleva- tion of 6,000 feet and which would serve 28,490 acres. The second pump would lift the water not used under this canal a further distance of 135 feet to the Bisti Canal at an elevation of 6,136 feet to irrigate the remaining 26,240 acres of land. With the joint Shiprock Main Canal diverting from the Navajo Reser- voir 207 feet lower than the carol in Plan D-3, less dead storage cap1city in the resorvoir would bo required. A total reservoir capacity of 1,205,000 acro-foet would be required, of which 980,000 acre-feot.would be active capacity, 12,000 acre-feet would be dead storage, and 213,000 acre-feet would moet silt storage requirements for 100 years. The samo lateral and drainage system would be roquired as in Plan D-3. 10
