<br />I <br /> <br />Water Year 1993 <br /> <br />Under most probable inflow conditions during the 1993 water <br />year, the Lake Mead water level is expected to be drawn down <br />to elevation 1167 feet at the end of June 1993. At that level, <br />the lake will have in active storage approximately 18.5 million <br />acre-feel. During water year 1993, a total of approximately <br />8.6 million acre-feet is scheduled to be released from Lake <br />Mead under most probable conditions, a\l passing through the <br />powerplanl. <br /> <br />The outlook for lowest and highest monthly releases of 1993 <br />will be about 460,000 acre-feet and 1,070,000 acre-feet, <br />respectively. Drawdown, during the peak large mouth bass <br />spawning period in April and May, is planned to be near the <br />limits of decline recommended in a July 1982 final report by <br />the Arizona Game and Fish Department and the Nevada <br />Department of Wildlife. That report summarized results of a <br />5 year study and recommended a drawdown rate ofless than <br />2 inches per day. <br /> <br />ACTUAL STORAGE 1992 <br /> <br />MILLION ACRI!-FI!lrr <br /> <br />. <br />1 <br />0 ,/ " <br /> / ~ '-- <br /> ./ <br /> <br />. <br /> <br />. <br /> <br />2 <br /> <br />11 <br />dS' +0" 0"''' ,..+ ~., +~ .;1~ +~ ~+ ~.., .;> ..~ <br /> <br />MOST PROBABLE RELEASES 1993 <br /> <br />TltOU8AHD ACRe..f~ET <br />1200 <br /> <br /> --,---, <br /> -- <br /> / \ <br /> / V ......, -..... <br /> I'--. <br />----.. ./ <br /> <br />1000 <br /> <br />.DD <br /> <br />.DD <br /> <br />.D. <br /> <br />..0 <br /> <br />. <br />;p +o~ Qt,..tI ")~ <(f(,'t; .tI'~ ~<t- +~ ~~ ~.... ~o. ~~ <br /> <br />MOST PROBABLE REGULATED INFLOW 1993 <br /> <br />lltOUSAND ACRE.FEET <br />"M <br /> <br /> >--< <br /> ....... <br />/ /' ""- V <br /> <br />1000 <br /> <br />... <br /> <br />'D. <br /> <br />... <br /> <br />... <br /> <br />. <br /><1'''' +0" Q"''' ,~ '" ~~ .;1"" +~ l' ~" ~'" .# <br /> <br />MOST PROBABLE STORAGE 1993 <br /> <br />MILLION ACRe-fEET <br />.. <br /> <br />I <br /> ,.- ......, <br /> "'-, <br /> " <br /> <br />21 <br /> <br />'0 <br /> <br />,. <br /> <br />1.A '" ..
