<br />I <br /> <br />Because the level of Lake Powell has dropped considerably <br />since 1987, the risk of releases greater than powerplant capacity <br />during wate'r year 1992 is negligible. Reservoir storage is <br />projected to continue to decline through the fall and winter, <br />reaching a seasonal low in March 1993 of about 90 feet from full <br />at 12,800,000 acre-feet. <br /> <br />During water year 1993, the minimum release objective of 8.23 <br />million acre-feet as set forth in the Operating Criteria will be <br />met. Under most probable inflow conditions, the reservoir will <br />only recover to a level about 63 feet from full or 15.7 million <br />acre-feet. Due to the extended drought, it will take <br />approximately 10 years of average inflow to refill the reservoir. <br /> <br />During water year 1993, the interim flow restrictions placed on <br />the releases from Glen Canyon in 1992 will continue. These <br />interim flow restrictions are based on the best technical <br />information available and are designed to minimize any damage <br />to downstream resources until a Record of Decision is made on <br />the Glen Canyon Environmental Impact Statement (GCEIS) <br />SDme time in 1994. <br /> <br />ACTUAL STORAGE 1992 <br /> <br />..IWON ACRe-FEET <br />.. <br /> <br />.2 <br /> <br />.. <br /> <br />,. <br /> <br />18 <br /> <br />14 <br /> <br />./ <br /> <br />-, <br /> <br />:} .l' 0"<- )~ <<-" ~-t ~., ~~ f>'" f>" I' ..(J <br /> <br />PROJECTED RELEASES 1993 <br /> <br />ntOUSA.ND ACAI!-FI!IIT <br />1200 <br /> <br />~B I.
