Show APPENDIX J 289 which would have the net effect of reducing California's rights from 5,362,000 acre-feet to about 3,800,000 acre-feet per year, a quantity less than the vested rights which California's old agricultural areas possessed prior to the construction of Hoover Dam, and which would deprive California of virtually all benefit from the flood water salvaged by that dam. The purpose of Arizona's suit is to quiet title to enough water to supply the Central Arizona Project, in addition to her existing and authorized projects. The Central Arizona Project is a proposal to lift 1,200,000 acre-feet of water 985 feet, and transport it some three hundred miles to the Salt and Gila River Valleys, at a total cost of about $800,000,000, and an average cost of about $2,000 per acre directly served. Upper Basin Threat The second challenge is from the four upper States of Colo- rado, New Mexico, Utah and Wyoming. These states are asking Congress to authorize the construc- tion of the Colorado River Storage Project in the Upper Basin. It would cost a billion and a half dollars. Of this, about half would be spent to build a dozen to fifteen irrigation projects, at an average cost in excess of $ 1,000 per acre, and about half to build six large reservoirs which would store 48,000,000 acre- feet, or over three years' flow of the river, and generate power to be sold to subsidize the irrigation projects. Th novel feature of this scheme, aside from its cost (twice that of tva and eight times that of the Boulder Canyon Pro- ject), is that, unlike any other projects, the six power reservoirs are to be built below, not above, the irrigation projects, and none of the water stored will be used in the Upper Basin for irrigation. They are power dams. The best-known of these would be Glen Canyon Dam, at the upper end of the Grand Canyon, and Echo Park Dam, which would flood a portion of the Dinosaur National Monument in Colorado. The water stored by these dams could only be consumed in the Lower Basin and Mexico. The Upper states assert the right to store and withhold this water from the Lower Basin for power generation under inter- pretations of the Colorado River Compact which would re- duce the quantity of water reaching Hoover Dam from an |
