<br /> <br />Now, if I were writing a current hydrographic report on the <br />Colorado River with this long range drouth story in mind, I think I <br />would sum it up in one sentence---"Don't expect too much from the old <br />Colorado." It's a drouth stricken stream if there ever was one. I've <br />often had to make a comparison between the Colorado River and the <br />Columbia River. The watersheds are almost identical in area and yet <br />the Columbia River furnishes ten times the norm for the Colorado River. <br />The water users in the Northwest boast that they have no controversies <br />over water. Of course they never have controversies because water is <br />plentiful with much to spare. We would all get along well together if <br />there was more of a surplus on the Colorado, but water supply engineers <br />say that we have to take into account that the long pull of the Colorado <br />River could easily be overloaded, and we just mustn't expect too much <br />of the tired, old stream. <br /> <br /> <br />Mr. Do w d : This drouth imposes no immediate threat to the areas <br />lying below Hoover Dam. No doubt it is a different story on the upper <br />areas and on some of the other tributaries. There still is about <br />13,000,000 acre feet in Hoover Dam which is about half of the usable <br />capacity. Had we known that this year was going to be as bad as it was <br />I believe there would have been a request made that Hoover Dam be <br />operated in accordance with the terms of the Boulder Canyon Project <br />Act, which was to reServe first for domestic and irrigation use, second <br />to power, which of course would have meant about a 25% cut in the power <br />output of Hoover, and would mean some cut, at least in kilowatts, for <br />this portion of the year in the output of Davis Dam. The planned <br />operation for the future when the volume had reached a point where water <br />was getting short, would be that the release from Hoover annually would <br />be the irrigation and domestic demand, but seasonally it would be in <br />accordance with the power users' wishes, the water to be re-regulated <br />at Davis Dam. In other words, the excess winter release from Hoover <br />would be stored in Davis and would be released from Davis during the <br />summer time when the irrigation demand is greatest. That, of course, <br />has not been done to any great extent. This next spring, if conditions <br />look as bad as they did the last spring, I think there will be a request <br />that the releases from Hoover on an annual basis be reduced to the <br />irrigation and domestic demand which wuld cause a great cut in power. <br /> <br />At the present time there's about 5,000 second feet flowing unused into <br />the Gulf of California. This is 5,000 second feet over and above the <br />irrigation and domestic demand which of course is a loss of water. What <br />concerns me more is the long time view of the flow of the Colorado River. <br />At the time the compact was negotiated, the negotiators had in mind that <br />the yield of the Colorado River system, which includes the main stream <br />and all its'tributaries, would be in the neighborhood of 20,000,000 acre <br /> <br />- 25 - <br /> <br />
