l5owe<]� <br />LajCe I M[ 'Qe as of June 30,2004 is approximately 10.476 MAP and is <br />projected to be about 9.5 MAP at the end$f this water year. This is the lowest level <br />since Powell began filling in March 1963. This is not unprecedented, as Powell got <br />very low in the early 1990's as well. Powell is doing its jobl At the cu rent rate of <br />decline during this drought, we can count on Powell to do its job for another 3.5 <br />Al <br />A ww <br />Lake Mead <br />Lake Mead storage at the end of June is 14.086 MAP and is projected <br />to be about 14.0 MAP at the end of the Water Year. <br />Storage in Mead is almost always about equal to that in Powell <br />because of equalization required between the 2 reservoirs. <br />However, since Powell is below the 602(a) storage level the minimum <br />objective release is 8.23 MAP. <br />This is because the Upper Basin to date has guaranteed 8.23 MAF and <br />thus Mead only drops .7 to .8 MAP a year during drought conditions. <br />A quick look at storage elevations in Mead shows they are currently <br />sitting at about 1127 which is will above the minimum power elevation <br />of 1050 and will above Southern Nevada's intakes which are at 1047 <br />and 1000 feet MSL respectively. <br />Fbw Belw/Haever Oem In TlwueeMS of Acrs {eN per Vp,, W+NrYnre 190] 1°]009 <br />"s ?i,r <br />. grEage3sa "s_F.�FYika <br />Lower Basin releases have been around 9.3 to 9.4 MAF annually.
