INTRODUCTION <br /> <br />A, Background - Background questions should be answered to establish the need for <br />and purpose of action. The involved agencies need to clearly defme historic and current <br />management of the areas and/or resources for which they are responsible.

Operating criteria to be defmed include annual target storage levels (fill by <br />July 31 and drawdown about 29 ft. to elevation 7,490 by December 31) and limiting factors such <br />as the use of the Crystal bypass and power outlets, and dam size and integrity considerations. <br /> <br />Gunnison meeting participants suggested that the Aspinall Unit has historically been operated to <br />protect the Upper Gunnison Basin from senior water right demands (including decrees of the <br /> <br />11 <br />
