<br />Water Year 1994 <br /> <br />PROJECTED CRYSTAL RELEASES 1994 <br /> <br />For water year 1994 operations, Blue Mesa Reservoir was <br />drawn down to at least an elevation of 2282.8 meters (7490.0 <br />feet) by December 31, 1993, in order to minimize icing <br />problems in the Gunnison River. Blue Mesa will continue <br />to be drawn down through April 1994, to a level that will <br />accommodate the most current probable inflow scenario and <br />accomplish the release objectives with minimum powerplant <br />bypasses. <br /> <br />IIlWotI CUBIC IIEnM <br />500 <br /> <br />o-p OB IN - PROfI+ l'RO I'" ~ <br /> . <br /> >-- . <br /> / .\ <br /> / , <br /> It":. ~ t- :--.. <br /> / /' ~ <br /> ...., ./ <br /> <br />ntOUUoIID ACIII-,UT <br />.... <br /> <br />- <br /> <br />24 <br /> <br />lOG <br /> <br />.. <br /> <br />.00 <br /> <br />.. <br /> <br />The minimum release objective of the unit is to meet the <br />delivery requirements of the Uncompahgre Valley Project <br />and to keep a minimum of 8.50 cubic meters .per second <br />(300 cubic feet per second) flowing through the Black <br />Canyon of the Gunnison National Monument. If the 8.50 <br />cubic meters per second (300 cubic feet per second) <br />minimum objective cannot be maintained due to low inflow <br />and storage conditions, the release may be reduced to 5.66 <br />cubic meters per second (200 cubic feet per second). Under <br />all but the most adverse inflow scenarios, Blue Mesa is <br />expected to Iill in the summer of 1994 and flows through the <br />Black Canyon of the Gunnison National Monument are <br />expected to be above the minimum release objective during <br />the summer months. The filling of the reservoir next year <br />will ensure that reasonable specific releases required to study <br />the protection and improvement of habitat for endangered <br />fish can be accommodated. The forecast runoff for the <br />spring of 1994 will be monitored to achieve these objectives. <br />To protect the blue ribbon trout fIShery in the Black Canyon <br />and maximize recreation potential, releases during 1994 will <br />be planned to minimize large fluctuations in the daily and <br />monthly flows. <br /> <br />'00 <br /> <br />, <br /> <br />)- .p #' ~ ~ ;- ~ +~ ~ ~" ~ ". <br /> <br />BLUE MESA UNREGULATED INFLOW 1994 <br /> <br />IIrwOtl cu..c III'I'Dlt 1HOU&MD ACII..,.O' <br />100 ... <br />I""~B ,. *MOOT~~ +PRC'~ <br /> <br />100 AGO <br />AGO / ... <br />100 / ... <br /> 1\ <br />100 \~- '0 <br />/ <br />'00 ~ .....N .. <br /> <br />. . <br />.I F'.p ~';-".F ,I' t>" ~, <br /> <br />ACTUAL BLUE MESA STORAGE 1993 <br /> <br />PROJEC'TlED BWE MESA STORAGE 1994 <br /> <br />IIIL.UC>>I CU.tc ..nus <br />'ADO <br /> <br />100 <br /> <br /> / r---., <br />"- / <br /> r--..... <br /> <br />THOUIAJUJ AClU-FBT <br />11.. <br /> <br />IIIUJC* cu.c ...,.,. <br />1_ <br /> <br /> .." lOB MI. ....
