<br />M3~ {5 <br /> <br />fI' <br /> <br />CHAPrER I <br /> <br />PlANS OF DEVELOPMENT <br /> <br /> <br />90 airline miles south for irrigation of lands in New Mexico. Four of <br />the reservoirs would be located on streams above the intercepting canal, <br />and the fifth would be at an offstreatl site about midway along the canal <br />to reregulate the diverted flows for meeting seasonal irrigation needs. <br />The main canal would consist of a series of open earth canals, bench <br />flumes, tunnels, and siphons. The conveyance system, including reser- <br />voir feeder canals, main canal, and main laterals, would have a total <br />length of about 265 miles. The reservoirs and canal collection systems <br />north of thE! Colorado-New Mexico State line would be practically the <br />same as in the Elm Juan-Chama project plan for transmountain diversion <br />of water to :the Rio Grande Basin. <br /> <br />Water supply and operation studies, with allowances made for the <br />potential dQwnstream within-basin developments including a Shiprock <br />project of 113,900 acres, indicate that an adequate supply could be <br />developed for irrigation of approximately 70,000 acres of new land <br />under this plan. Of this acreage, nearly half would be within the <br />boundary of the Jicarllla Indian Reservation. <br /> <br />The features included in Plan A, their ca:racities, and estimated <br />costs are tabulated on :rages 4 and 5. The project construction cost is <br />estimated at .$161,528,000 or $2,308 an acre, and annual operation, main- <br />tenance, and replacements costs are estimated to total .$316,000 or .$4.51 <br />an acre.
