<br />V'.'..;.. v ~;;.. <br /> <br />COLORADO BASIN <br /> <br />Basinwide Conditions Assessment <br />The SWSI value of -0.9 indicates that for May the <br />basin water supplies were near normal. The Natural <br />Resources Conservation Service reports that June 1 <br />snowpack is 18% of normal. Flow at the gaging station <br />Colorado River near Dotsero was 3,058 cfs, as compared to <br />the long-term average of 4,588 cfs. Storage in Green <br />Mountain, Ruedi, and Williams Fork reservoirs totaled 111 % <br />. of normal as of the end of May. <br /> <br />Outlook <br />With the Colorado-Utah State line flows 5.000 cfs <br />less than the 50 year average and the Colorado River below <br />Glenwood Springs flows 2.000 cfs lower than its 34 year <br />average, the basin is laaking natural flows. Few reservoirs - <br />namely Ruedi, Dillon, and Vega ~ are anticipated to fill or <br />have filled while others. Granby, Williams Fork, Wolford, <br />and Green Mountain - wUl not get their physical fill. <br /> <br />Administrative/Manaoement Concerns <br />The Bureau of Reclamation placed a storage call for <br />Green Mountain Reservoir effective April 30, If the basin <br />.stays dry without rainfall and the senior Shoshone 'call . <br />comes on before mid-July, Green Mountain Reservoir may <br />not fill and the substitution provisions, as provided. for in the <br />Blue River decrees, will be in effect. <br /> <br />Public Use Impacts <br />None. <br /> <br />Jun-01 <br /> <br />COLOlWlOIlASIN SWSI HSTalI' <br /> <br />~ --- ... --- _. <br /> <br /> <br />I- <br />W <br />~ 2 <br /> <br />w <br />=>, <br />~ <br />x <br />~o <br />~ <br /> <br />., <br /> <br />.. <br />Ja>92J8>8l.ior>&l____.......Io'o(I)_ <br />MONIH I 'r1;AR <br /> <br />. ~ . <br /> <br />COlORAOO RIVER IIR OOTSERO.
