ALLISON ON THE COLORADO RIVER PROBLEM 365 For 100,000 acres this would be at $81.74 per acre, as compared to $102.00 per acre, estimated by the All-American Canal report. The saving in maintenance on the pumping route will more than pay for the power and operation of the pumping plant. Canal for East Side Mesa Lands.—Lift from the Alamo Canal in Mexico, at Elevation 93, 2,600 sec-ft. to the top of the mesa west of the sand-hills, at Elevation 160, to irrigate all the East Side Mesa lands, as contemplated in the All-American sand-hill route (160,000 acres in the United States and 30,000 acres in Mexico), together with 10,000 acres not reached by the All-American route. To lift this flow from the Alamo Canal, a 20-ft. head pumping plant would be required, the water would be carried in a Mexican canal for a distance of 5 miles to the foot of the mesa, where it is lifted in two or more lifts 47 ft. to the top of the mesa; the canal on the mesa follows along the westerly edge of the sand-hills (Fig. 19) to Iris, on the approximate route of the pumping canal lateral contemplated in the All-American program. The cost would be as follows: Pumping plant, 20-ft. lift...............___........... $ 500,000 Pumping plants, 47-ft. lift....___..................... 850,000 Main Canal to Iris, plus 100,000 acres of lateral system.. 4,466,800 Plus additional 100,000 acres of lateral system at $16..... 1,600,000 Total........................................... $7,416,800 Under the All-American sand-hill route the cost per acre is $85.20, with a cost for maintenance which will operate the pumping plants under the Mexican route. Canal for West Side Mesa Lands.—Construct a canal from the Cerro Prieto Canal in Mexico, at Tule Check, following a grade contour along the western slope of the valley above the line contemplated by the All-American Canal System, irrigating agricultural land as follows: Lands covered by All-American Canal System......... 20,000 acres New lands above All-American Canal System........ 10,00 " Pump lands covered by All-American Canal System.... 23,000 " Total ................___.................___ 53,000 acres The cost of this project would be as follows: Enlarging Solfatara and Cerro Prieto Canals in Mexico, 28 miles......................................... $105,000 Head-works at Tule Check................ .......... 80,000 New canal to International Boundary Line (19 miles).. 200,000 Building "B" Line Canal on new location plus enlargement for additional acreage........................ 641,000 Total...................................... $1,026,000
