The active <br />storage was 3,583,000 acre-feet. <br />Releases for power production <br />caused the reservoir to recede ]3 <br />feet during the rail and winter to <br />elevation 6,023 feet. The April. <br />July 1975 runoff above Flaming <br />Gorge was 1,635,000 acre.feet, or <br />14.3 perc.ent of the lo-ng-time aver- <br />age. With this runoff, Flaming <br />Gorge filled on July 28, 1975, at <br /> <br />elevation 6,040 feet with an active <br />storage of 3,750,000 acre.feet of <br />water. (Chart 2.) <br /> <br />During August, September, and <br />October, reservoir releases were <br />increased to above normal. The <br />reservoir water le\'el was drawn <br />down so releases during November <br />could be reduced to permit opera- <br />tion of construction equipment in <br />the river below the dam to remove <br />material deposited during s.pillway <br />testing in July 1975. <br /> <br /> OUTFLOW <br /> UPPER aUARTI LE <br /> 4 <br /> 3 <br /> 2 <br />0 0 <br />z <br />0 4 <br />u <br />w 3 <br />w <br />~ <br />w 2 <br />w <br />. <br />u <br />" 0 <br />0 <br />u <br />0 4 <br />8 3 <br />= <br /> <br /> <br /> >" <br /> ".,,-,- <br />w ~ " ,.. ,; u z' <i <i > w > " <br />z ~ '" ~ z ~ '" <br />~ "i ~ w U 0 w ~ w "' ~ "' "i "i ~ w <br />~ "' ~ I 0 z c ~ ~ "' ~ "' ~ I <br /> WallrVelr Illi <br /> <br />a:: ri >- <br />~ ~ ~ <br />WatlrVlarllJ5 <br />
