Show 6 IV The drainage basin of the Colorado River in the United States has a total area of 240,000 square miles, of which 103,000 square miles are in Arizona, 4,000 square miles in California, 12,000 square miles in Nevada, 40,000 square miles in Utah, 23,000 square miles in New Mexico, 39,000 square miles in Colorado, and 19,-000 square miles in Wyoming. Approximately 43 per cent, of the total area of said basin is in Arizona, and approximately 90 per cent, of the total area of Arizona is in said basin. From the point where it enters Arizona to the point where it enters Mexico, the Colorado River has a fall of 3,230 feet, of which 2,200 feet occurs in Arizona, 650 feet on the boundary between Arizona and Nevada, 350 feet on the boundary between Arizona and California, and 30 feet on the boundary between Arizona and Mexico. That part of the Colorado River which flows in Arizona and on the boundary between Arizona and Nevada flows through an almost continuous series of deep canyons, the walls of which rise on each side of said river to a height varying from a few hundred feet to more than 5,000 feet, because of which said river in said canyon region is practically inaccessible. Throughout said canyon region there are numerous rapids, cataracts and other natural obstructions, because of which, and because of the great fall and rapid flow of said river, navigation thereof in Arizona and on the boundary between Arizona and Nevada has always been and is now utterly impossible. |
