<br />YAMPAlWHITE BASIN <br /> <br />Basinwide Conditions Assessment <br />The SWSI value of -1.2 indicates that for December <br />the basin water supplies were slightly below normal. The <br />Natural Resources Conservation Service reports that <br />January 1 snowpack is 92% of normal. Flow at the gaging <br />station Yampa River at Steamboat was estimated at 150 cfs, <br />as compared to the long-term average of 105 cfs. <br />December brought well below average precipitation <br />to the basins. While November precipitation was about 80% <br />of average, December's dropped to 69% of average. <br />Precipitation was down, and temperatures were above <br />average, resulting in declining snowpacks. By the end of the <br />month the basin-wide snowpack for the White, Yampa, Little <br />Snake and North Platte River Basins were 92%, 87%, 100%, <br />and 92%, respectively. <br />The first runoff forecast for the year released by the <br />Natural Resources Conservaiion Service, predict below <br />normal runoff for all of the basins. The forecasts, based on <br />end of December measurements, list the most probable <br />condition as 76% of average for the North Platte River near <br />Northgate; 83% of average for the Yampa River near <br />Maybell; 92% of average for the Little Snake River near <br />Dixon; and 83% of average for the White River near Meeker. <br /> <br />Outlook <br />The first runoff forecasts of the season are not <br />encouraging. The end of December snowpack for this year is <br />only 85% of the snowpack from last year at the same time. <br /> <br />Public Use Impacts <br />Winter activities are in full swing throughout the <br /> <br />basin. <br /> <br />'J <br /> <br />Jan-05 <br /> <br />" <br /> <br />-~ <br /> <br />, <br /> <br /> <br />, <br />~ <br /> <br />, <br />I!l <br />~ 0 <br />~ <br />c <br />~., <br />Ii <br />c <br />. <br /> <br />. <br /> <br />....,......-..cRJIo\(ICl.llr>O'l.-.az.llr>OllJroolMJor>Cll <br />""","'" <br /> <br />Y/lM'A RI\ER AT ~T, FtDN BY Wo\1ER 'tEM. <br /> <br /> I <br /> II <br /> II <br /> .....- / <br /> -- --- <br /> -------- ~ ..----- / <br /> ~ ~ --- <br />- . <br /> <br />100,axl <br />"',"" <br /> <br />~ lll,"" <br />~ 7O,cm <br />~ OO,OXl <br />o <br />It 50,"" <br />~ <0,"" <br />~ <br />~ XI,em <br />a Zl,"" <br /> <br />1~"" <br />o <br />Oct <br /> <br />..... <br /> <br />""'" <br /> <br />"" <br /> <br />"" <br /> <br />... <br /> <br />.." <br /> <br />-&-'v\ET(19E14) <br /> <br />__CRY'(1977) <br /> <br />_AVG <br /> <br />*-= <br /> <br />8 <br />
