<br />Net storage increase <br /> <br />1,300,000 a.f. <br /> <br />Evaporation and bank <br />storage losses <br /> <br />900,000 a.f. <br /> <br />I <br /> <br />Releases to Lower Basin 8,400,000 a.f. <br /> <br />Total runoff, water <br />year 1968 10,600,000 a.f. <br /> <br />All of the Upper Basin reservoirs will <br />have gained storage during water year 1968 <br />except Flaming Gorge, from which about <br />700,000 acre-feet has been released to im- <br />prove the power head at Glen Canyon. <br /> <br />During the same l2-month period, Lake <br />Mead will have gained about 700,000 acre-feet <br />of storage. <br /> <br />Lake Powell's water surface is now at <br />an all-time high at about 3550 feet elevation <br />with a surface storage of 9,850,000 acre-feet. <br />The lake is expected to remain near this level <br />until the spring runoff starts in 1969. The <br />release for water year 1968 will also be <br />about 8.4 million acre-feet. <br /> <br />I <br /> <br />Deliveries to tbe Lower Basin for the <br />first six years of tbe filling period will <br />total about 40 million acre-feet, leaving <br />about 35 million acre-feet or an average of <br />about 8.8 mil:_ion acre-feet per year for the <br />next four years in order to attain a total <br />delivery of 75,000,000 acre-feet for the ten- <br />year period, 1963-1972. Power loads should <br />be adequate to require releases of at least <br />this amount of water in the next four years. <br />The relatively low delivery for the past six <br />years was caused primarily by the low re- <br />leases of 1963 and 1964 which were necessary <br />to permit acquisition of minimum power levels <br />at Flaming Gorge and Glen Canyon. Only about <br />5,000,000 acre-feet was released to the Lower <br />Basin of a total inflow of about 12,700,000 <br />acre-feet in this two-year period. <br />
