<br />COLORADO BASIN
<br />
<br />"
<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 />Outiook
<br />With the Colorado-Utah State line fiows 5,000 cfs
<br />less than the 50 year average and the Colorado River below
<br />Gienwood Springs flows 2,000 cfs lower than its 34 year
<br />average, the basin is lacking natural fiows, Few reservoirs -
<br />namely Ruedi, Dillon, and Vega - are anticipated to fill or
<br />have filled while others - Granby, Wiiliams Fork, Wolford,
<br />and Green Mountain - will not get their physicai fill.
<br />
<br />Administrative/ManaQement Concerns
<br />The Bureau of Reclamation piaced a storage cail for
<br />Green Mountain Reservoir effective April 30, If the basin
<br />.stays dry without rainfall and the senior Shoshonecail
<br />comes on before mid-July, Green Mountain Reservoir may
<br />not fill and the substitution provisions, as provided for in the
<br />Biue River decrees, will be in effect.
