Show COMPACT-COMMENTS BY A. P. DAVIS A49 Question 7. Ij a reservoir of 30,000,000 acre-feet capacity had been in existence at that time, how much water would have been carried over from previous years to aid in meeting any deficiency? Answer 7. Plate XII-A, Senate Document 142, page 30, shows that starting in 1899 with a 26,400,000 acre-foot reservoir half full, the reservoir would have filled in 1900 and again in 1901, and the full demands for irrigating 1,500,000 acres below could have been met not only through 1902 but through the succeeding low years of 1903 and 1904. In addition, sufficient water would have been available for discharge through the months of low irrigation demand to maintain a year around output of 700,000 horsepower. Question 8. How many acres are now being irrigated; what additional areas can be irrigated from the main Colorado River, and what is the estimated cost of the reclamation of the lands in Arizona within the projects that have been investigated by the Reclamation Service up to the present time? Answer 8. Senate Document No. 142, gives the following figures, for lands irrigated in Arizona, 1920, from the main stream of the Colorado: Irrigated 1920, Arizona Main stream: Acres Parker project____________________________________________ 4, 000 Yuma project____________________________________________ 46, 000 Total, 1920_____________________________________________ 50,000. Additional irrigable, Arizona Main stream: Acres Cottonwood Island_______________________________________ 2, 000 Parker project___________________________________________ 106, 000 Mojave Valley___________________________________________ 26, 000 Yuma project____________________________________________ 75, 000 Cibola Valley____________________________________________ 16, 000 Isolated tracts___________________________________________ 4, 000 Total additional________________________________________ 229, 000 Cost data for most of the above projects are not available in sufficient detail to be of value. An engineer of the Indian Service estimated in 1920 a cost of $78 per acre for the Parker project, exclusive of storage, flood control, and power (S. Doc. No. 142, p. 55). Gravity lands on the Yuma project are subject to a construction charge of $75 per acre. 77831-48------16 |
