DAVIS A51 This would irrigate nearly 2,000,000 acres of land in addition to the acreage figured above, and since water must flow downhill, and since a reservoir at Boulder Canyon of the size proposed will completely control the stream at that point, it only remains to find the land to which this water can be profitably applied. Question 11. What information have you with respect to the Arizona High Line Canal plan? Answer 11. We have asked our field engineers for report on Arizona High Line Canal, which has just been received as follows: The Arizona High Line Canal as outlined more recently contemplates- A storage reservoir at or near Glen Canyon. Its capacity has not been stated in definite terms. A second dam at Boulder Canyon to be built to elevation 1,350 feet, or 1,375 feet, or a dam at the lower end of the Grand Canyon of a less height that will raise the water to the same elevation. A tunnel from the Detrital Sacramento Wash through the Black Mountains some 15 or 20 miles in length which would come out on the western side of the Black Mountains in the general region of Eldorado Ferry, water to be delivered at the end of the tunnel at an elevation not less than 1,325 feet. A large canal, extending southward and generally parallel with the Colorado River, following along the west side of the Black Range, the greater portion of which would be in tunnel from a point back of Eldorado Ferry to Mount Davis. These tunnels may aggregate another 15 miles or more; thence an open canal crossing a detrital wash country with many deep washes southward along the Blue Ridge and Black Mountains, crossing Sacramento Wash and the main line of the Santa Fe Railroad a few miles from Franconia; thence south and southwesterly toward the Colorado River, where it would pass around the west face of the Chemehuevi Mountains and the Williams Mountains; thence easterly along the north side of the Williams River to a crossing on the WTilliams River. Through this region there would be more or less tunnel work. A crossing of the Williams River either by a high dam in that stream where the river is confined in a box canyon, through the Rawhide Mountains, or by a high aqueduct or a large siphon. Some surveys are being conducted at the present time by the Arizona Engineering Commission to ascertain data on this crossing. The canal would then run westerly along the south side of the Williams River through the Buckskin Mountains, tunneling through the Osborne Pass; thence in a general southerly direction through the Cactus Plain to the general region of Bouse. The first tracts of tillable land of any consequence encountered would be that lying within what is commonly called the Bouse Valley. The proposed canal line would probably cross the Phoenix branch of the Santa Fe Railroad between Bouse and Vicksburg. What the irrigable area of these valleys amounts to is as yet an undetermined quantity. The main canal would continue in a southeasterly direction, passing to the south of the Little Harqua Hala Mountains through a pass that has been estimated to be from 16 to 25 miles in length. This part of the construction would be a deep cut, the depth of the cut depending upon the elevation at which a canal would riach that point. Before reaching this cut the canal would bifurcate, some of the water being taken south and southwesterly to irrigate other possible |
