<br />Every measure will be taken to prevent such an uncontrolled powerp1ant bypass this spring in <br />order to protect the Grand Canyon ecosystem downstream of Lake Powell. In this regard, <br />technical discussions have recently occurred regarding the hydrologic triggering mechanisms <br />under which beach/habitat-building flows could be released from Glen Canyon Dam. The <br />Technical Work Group has evaluated and the Adaptive Management Work Group has <br />recommended the following triggering criteria for the release of a beach/habitat-building <br />flow: <br /> <br />1. If the January forecast for the January-July unregulated spring nmoffinto Lake Powell <br />exceeds 13 maf(about 140 percent ofnonnal), or <br /> <br />2. Anytime a Lake Powell inflow forecast would require a powerplant monthly release <br />greater than 1.5 maf, then a beachihabitat-building flow could be released from Glen Canyon <br />Dam if then deemed appropriate from an environmental perspective. <br /> <br />...~:; ~'~:",:,""" i-, .~~.:;.o'_~~"""_\~"....:~.!'~'" 'i-.::,...;._,.'.~f i:;:'::~;';::!I'~4.""""~'" :""..'), ~ '"' .....~ '1:,"-" :.... .~. .
