<br />completely emptying Lake Powell, since there would be no storage that could <br />be released during drought periods, only temporary storage during the <br />runoff season which would then be evacuated when innows dropped. Under <br />the assumption that elevation 3500 would be viewed as a type of minimum pool, <br />annual releases to the lower basin would be about the same as the full evacuation <br />alternative, Evaporation at Lake Powell would be reduced from current levels by <br />aboul two-thirds. but evaporation at Lake Mead would increase slightly due to a <br />higher long-term lake level. Ifsome drawdown below elevation 3500 feet were <br />permitted to control high runoff years. this would eliminate months of power <br />generation capability but would reduce the re-inundation of-canyon reaches <br />upstream, <br /> <br />g - This concept could result ill greater connict between lake and downstream <br />river interests. since both resources could be significantly compromised from <br />current levels. The recently issued Record of Decision on the GCDEIS would <br />be moot and another ElS process would be required to resolve the newly <br />created connicts between uses. As with the Brower proposal, legislation <br />would be required to bring Lake Powell down to this lower level. <br /> <br />9 <br />
