<br />COLORADO BASIN <br /> <br />Basinwide Conditions Assessment <br />The SWSI value of -0.1 indicates that for April the <br />basin water supplies were near normal. The Natural <br />Resources Conservation Service reports that May 1 <br />snowpack is 88% of normal. Flow at the gaging station <br />Colorado River near Dotsero was 1,384 cfs, as compared to <br />the long-term average of 1,779 cfs. Storage in Green <br />Mountain, Ruedi, and Williams Fork reservoirs totaled 123% <br />of normal as of the end of April. <br />Snowpack for the entire Colorado River basin is only <br />at 88% of average, but this represents a 57% increase over <br />last year's May 1 snowpack, according to the "Colorado <br />Basin Outlook Report May 1, 2005" (NRCS). Significant <br />variations occur throughout the basin. The Plateau Creek <br />basin is doing very well at 145% of average, while the Blue <br />River, Willow Creek, Upper Colorado River, and Muddy <br />Creek (below Wolford Mtn. Res.) basins are at all less than <br />80% of average. Variations occur within basins, too, such as <br />the Roaring Fork River basin where the Crystal River has <br />above average snowpack and the Frying Pan River has <br />below average snowpack. <br /> <br />Outlook <br />The NRCS forecasts that April-July stream flows will <br />be less than or 85% of average at Lake Granby inflow, <br />Muddy Creek below Wolford Mtn. Reservoir, Dillon Reservoir <br />inflow, Williams Fork Reservoir inflow, Green Mountain <br />Reservoir inflow, Eagie River below Gypsum, Colorado River <br />near Dotsero, and Ruedi Reservoir inflow. Colorado River <br />near Cameo stream flow is forecasted at 81% of average. <br />Near average stream flow is forecasted for the Roaring Fork <br />River at Glenwood Springs. <br /> <br />: <br /> <br />May-OS <br /> <br />""~ <br /> <br />~ <br /> <br /> <br />w <br />3 <br />< <br />> , <br />~ <br />o <br />z <br />-., <br /> <br />~ <br />o <br />: <br /> <br />. <br /> <br />. <br />.-,.re .-..w J<r>Ql ......99 JIIl.Ill .Jon.C1 Jrwl-CIl Jorl.03 Ja1.04 Ja1.al <br />-,- <br /> <br />a::t.<P.AOO ~ tR OO'TSER), FI..JJN BY WATER 'tEAA <br /> <br />~OJO.lXXl <br /> <br /> ./'" ..... <br /> / <br /> / <br /> / ~ ~ <br /> V /' <br />....- <br /> - <br /> <br />~ooo.lXXl <br /> <br />" <br />. <br />d; 2,500,CXXl <br />. <br />"' <br />~2,oco.CXXl <br />~ <br />~ <br />~ 1,500,OXl <br />~ <br />~ 1,OOO,lXXJ <br />" <br />o <br /> <br />OJO.lXXl <br /> <br />o <br />""""""'.....Feb"""'.............Jt<yAug.... <br /> <br />__ YET (1964) <br /> <br />--CRY(roJ2) <br /> <br />-*- 2005 <br /> <br />~AVG <br /> <br />~A11\IEFESEf&ORS <br /> <br />"'."" <br /> <br />70,"" <br /> <br /> <br />00."" <br />~ <br />~ 00,(0) <br />05 <br />[40,"" <br />1;; <br />~3),00) <br />~ <br />" <br />"'-"" <br /> <br />i0,em <br /> <br />o <br /> <br />Geeo........., <br />I A\g. 04f3) CcnfIis <br /> <br />...... <br /> <br />WliaT6 Fak <br />.
