<br />003151 <br /> <br />", <br /> <br />CHAPTER I <br /> <br />PIANS OF DEVELOPMENT <br /> <br />two pipes to the main distribution canals. In one pipe with a capacity <br />of 597 second'-feet, water w'ould be raised 286 feet above the pumps to <br />the Gallegos G'3.nal from which 29,370 acres would be irrigated. In the <br />other pipe with a r.ac:nc5,ty of 744 second-feet, water would be raised <br />407 feet above 't'n0 PC'1J,PS to the Bisti Canal froJU which the relll!loining <br />36,570 acres of project land would be irrigated. <br /> <br />A lateral system to distribute water to all project lands would <br />be required. Only about 1,000 acres are expected to require drainage <br />by artificial means. <br /> <br />Plan D-2 <br /> <br />. <br /> <br />The same South San Juan project area would be served under Plan D-2 <br />as under Plan D-l. The Navajo Reservoir would be constructed to a <br />capacity of 1,954,000 acre-feet, including an active capacity of <br />1,025,000 acre -feet. The joint Main Gravity Canal would be constructed <br />approximately 245 feet higher than the canal planned for the 113,900- <br />acre Shiprock project alone and would have a capacity of 2,950 second- <br />feet and a length of 26 miles. Water for both projects at the end of <br />the joint canal would drop 225 feet through a penstock to hydraulic- <br />turbine-driven pumps. From the pumps, water would separate in the <br />same manner as in Plan D-l with the same capacity in each line. The <br />water pumped to the Galleges Canal would be raised 292 feet and to <br />the Bisti Canal 413 feet. <br /> <br />The same lateral system and drainage system would b!3 required as <br />in Plan D-l. <br /> <br />Plan D-3 <br /> <br />. <br /> <br />Under Plan D-3, 57,000 acres of land would be irrigated in the <br />South San Juan project area, including 19,150 acres in the Navajo <br />Indian Reservation but outside the Shiprock project area. The same <br />lands would be irrigated as in Plan D-l except that the Bisti Canal <br />would not be extended to 10,700 acre s in the southern part of the area. <br />The Navajo Reservoir would be constructed to a capacity of 1,672,000 <br />acre-feet, including an active capacity of 980,000 acre-feet. The <br />joint Main Gravity Canal from Navajo ram to the hydraulic -turbine- <br />driven pumpdng plant ,;auld be constructed approximately 207 feet higher <br />than the canal planned for the 121,700-acre Shiprock project alone and <br />would have a capacity of 2,900 second-feet and a length of 26 miles. <br />This section of the canal would serve by gravity the same 1,760 acres <br />of South San Juan pro,ject lands on Pauline Mesa as would be served by <br />Plans D-l and D-2. The remaining water for both projects would drop <br />190 feet tlu'ough a penstock to hydraulic-turbine-driven pumps. In one <br />discharge line with a capacity of 597 second-feet, water would be raised <br /> <br />8 <br /> <br />
