<br />YAMPAlWHITE BASIN <br /> <br />Basinwide Conditions Assessment <br />The SINSl value of -3.1 indicates that for April Ihe <br />basin water supplies were below normal. The Natural <br />Resources Conservation Service reports that May 1 <br />snowpack is 53% of normal. Flow at the gaging station <br />Yampa River at Steamboat was 437 cfs, as compared to the <br />long-term average of 605 ds <br />April brought near normal precipitation to the basin. <br />However, warm temperatures and high winds caused the <br />snowpack to conllnue lis early mett While the basin <br />received 97% of average precipitation for the month, the <br />snowpack dropped 10 62% of average on the North Plalle <br />drainage. 48% of average on the Yampa, and 62% of <br />average on the White River. Only the high elevation snow <br />remains. The combined snowpack on the Yampa!vVhIle <br />Rivers is the lowest In the Slate at 50% of average <br /> <br />Outlook <br />The May 1st runoff forecasts. prepared by the <br />Natural Resources Conservahon Service. dropped slightly <br />from the previous month. The percent of average runoff <br />under the mosl probable forecast is 32% for the North Plalle <br />River near Northgate (down from 40%) 50% for the Yampa <br />River near Maybell (down from 54%), and 55% for the White <br />R,ver near Meeker (down from 59%) These forecasts are <br />down significantly from the same time last year, and only <br />slightly better than those for 2002. The runoff period will be <br />shorter than average this year. with the peak expected to <br />occur two to three weeks early. <br /> <br />Administrative/Management Concerns <br />Calls for administration have begun to increase With <br />several more streams going under administration this month. <br />It is unlikely that Yamcolo and Stillwater Reservoirs on the <br />Bear River in District 58 will fill. Reservoirs In North Park are <br />near full and Will be able to prOVide much needed <br />supplemental supplies to their users. Absent significant <br />summer rains. the basin will be faced with an extreme <br />drought situation this summer <br /> <br />Public Use Impacts <br />The rivers in the baSin are flowing at high levels as <br />the runoff strengthens Extreme caution should be exerCised <br />when participating In water based recrealton until flows begin <br />to recede <br /> <br />May-04 <br /> <br />-- <br /> <br /> <br />t <br /> <br />" <br /> <br />-..--------- <br />.-- <br /> <br />Y.....''A_Ar~rfl.!M'BV.....~VEAR <br /> <br />~~. <br /> <br />=~. <br /> <br />--, <br /> <br />I <br />l~(XJH r- <br />~ <br />'=~ <br />g <br />. <br />~'~ClXI' <br />C <br />, <br />~ 'OOClXlT <br />, <br />u <br /> <br />~r <br />+ <br />I . <br />./ <br /> <br />~~. <br /> <br />~. <br />-=:r= <br /> <br />.
