Starting <br />March 10, 1972, releases were gradually in- <br />creased to 1,650 c.f.s, on March 16 to force the <br />geese to build their nests on higher ground. <br />After the actual geese-nesting period, a maxi- <br />mum of 14,300 c.f.s. had to be released during <br />the first part of June when the reservoir Was <br />spilling, The reservoir as of September 30, 1972, <br />had 342,300 acre-feet of active storage at <br />elevation 6,506 feet, near maximum water Sur- <br />face level. <br />During water year 1972, the Green River <br />April-July inflow to Fontenelle was 163 percent <br />of the long-time average and releases to con trol <br />the peak inflow reached 14,300 c,f.s, Without <br />Fontenelle Dam, peak flow would have reached <br />18,700 cJ,s, and the larger flow would have <br />caused damage below the dam, (Chart I) <br /> <br />2 <br />
