Show 130 PROBLEMS OF IMPERIAL VALLEY AND VICINITY. WHITE RIVER BASIN. The only apparent power possibility in the headwaters is below Stillwater • reservoir site on White River, where, if Yellowjacket project is built, the replacement storage from the reservoir for present rights near Meeker will give a good flow in low-water periods. Without doubt other small sites exist. Rangely reservoir site.-This lies near the west line of Colorado. The discharge at present averages 550,000 acre-feet, but extension of irrigation, it is estimated, will reduce this to 360,000 acre-feet, and if trie Deadmans Bench project is built there would be no water available.

A dam, raising the water surface 200 feet, will give 330,000 acre-feet of storage and provide a constant head of 160 feet below that-storage. As the reservoir is expensive, the desirability of this development rests largely on finding other sites below where head can be created to use the equated flow. It is to be expected that other dam sites exist above and below this point. Yampa and While rivers known undeveloped povjer sites. [Future discharges after irrigation depletion.] Index number on map.
