At operating level, Shadow <br />Mountain and Grand Lakes form one continuous body of water, with <br />Shadow Mountain Lake covering an area of 1,337 acres and the two <br />lakes at the common operating level covering 1,852 acres. During <br />periods when normal inflow to the lakes 1s inadequate to maintain <br />a uniform rate of flow through the Adams Tunnel, the lake level is <br />maintained by pumping fram Granby Reservoir. Controls provide for <br />automatic regulation of the water surface of Grand Lake within a <br />I-foot fluctuation limdt--between elevations 8366.0 and 8]67.0. <br /> <br />- ---~- <br /> <br />- <br /> <br /> <br />.:~?'~. <br />c$",~, <br /> <br /> <br />Shadow Mountain Lake - Outlet Works Right Foreground. <br /> <br />Shado'.
