Power <br /> <br /> <br />loads should be adequate to require releases of at least this amount of <br /> <br /> <br />water in the next 5 years. The relatively low delivery for the past 5 <br /> <br /> <br />years was caused primarily by the low releases of 1963 and 1964 which <br /> <br /> <br />were necessary to permit acquisition of minimum power levels at Fla~ng <br /> <br /> <br />Gorge and Glen Canyon. Only about 5,000,000 AF was released to the Lower <br /> <br /> <br />Basin of a total inflow of about l2,700,000 AF in this 2-year period. <br /> <br />The Flaming Gorge and Blue Mesa Reservoirs and Lake Powell achieved <br />seasonal maximum levels in July and will decline somewhat until the snow- <br />melt season next spring. <br /> <br />Glen Canyon reached a total storage of 8,645,000 AF on July 27, 1967, and <br />will recede to about 8,079,000 AF by next April for a vertical drop of <br />about 9.0 feet. <br /> <br />Flaming Gorge reached its alltime high on July 29, 1967, with 2,988,000 AF <br /> <br /> <br />of storage at elevation 6,Ol9 or 21 feet below its normal maximum level. <br /> <br /> <br />In order to augment storage in Lake Powell, we have scheduled relatively <br /> <br /> <br />high power production at Flaming Gorge for the coming year and expect the <br /> <br /> <br />reservoir to lose about 900,000 AF of storage and reach a content of <br /> <br /> <br />2,089,000 AF by April 1968. <br /> <br /> <br />7 <br /> <br />
