The Natural <br />Resources Conservation Service reports that December 1 <br />snowpack is 84% of normal. Flow at the gaging station <br />Colorado River near Dotsero was 924 cfs, as compared to <br />the long-term average of 1156 cfa.' Storage in Green <br />Mountain, Ruedi, and Williams Fork reservoirs totaled 77% <br />of normal as of the end of November. <br /> <br />Outlook <br />Snowpack started the month of November at about . <br />average' for the Colorado River basin but limited snowfall <br />amounts throughout the month caused the snowpack to drop <br />to 75% of average for the basin by early December. . Grand <br />Mesa had particularly low snowpack, with less than 50% of <br />average snowpack. <br />The senior Shoshone power call should remain on <br />the Colorado River mainstem until scheduled turbine <br />maintenance in January. <br /> <br />Administrative/Manaaement Con(ferns <br />Maintenance of stream gaging stations at critical <br />minimum streamflow sites will' continue to be a priority <br />throughout December and into January. 'Careful monitoring <br />of these sites, whicb typically are at snowmaking diversion <br />points, has not resulted in any curtailment to date this year. <br /> <br />Public Use Impacts <br />Streamflows should continue to meet or exceed <br />minimum flow limits, allowing several major ski areas to keep <br />up their snowmaking efforts. If typical December snowfall <br />occurs, most ski areas should have sufficient snowpack for <br />the upcoming, busy holiday season. However, at least one <br />ski area without snowmaking remained closed in early <br />December because of limited snowpack. <br /> <br />~..;_ .1. ~ <br /> <br />5--. <br /> <br />Oec~OO . <br /> <br />COLORADO BASlNSWSI HSItRf <br /> <br />.! <br /> <br />I- ... <br />w <br />;r 2 <br />W <br />:> 1 of: <br />..J <br /><< <br />> <br />X <br />W 0 <br />0 <br />;!; <br />>- .. <br />0: <br />a <br /> .2 <br /> <br /> <br />., <br /> <br />.. <br />....,.91 <br /> <br />Jln.82 _ _' Jor>9s ..... ~. _ <br />IIIClImi 1 'YIiAR <br /> <br />--1. <br /> <br />..... - <br /> <br />~: <br /> <br />COLORADO RIVER r-R OOTSERO. flCNV 8V WATER YEAR <br /> <br />600.000 -. --......--...--.. .--.- .. ...----. - .. ..........--c.,--...-. -.-....-...- ------..-.j <br /> <br />i 500,000 <br />u.. <br />~ 400.000 <br />~ <br />o <br />it :lOO.OOO <br />IU <br />> <br />~ 200.000 <br />;:t <br />::; <br />=> <br />c.> 100,000 <br /> <br />~ 80 CXXl <br />~ ' <br />co <br />g <br />~ 8O.0CXl <br />V) <br />.!!! <br />j <<>,lXXJ <br />:> <br /> <br />7 <br /> <br />120.000 <br /> <br />100.000 <br /> <br />:/O,lXXJ <br /> <br /> <br />f. <br /> <br /> <br />{) <br />oct <br /> <br />Noll <br /> <br />Dole <br /> <br />FW <br /> <br />JaR <br /> <br />Mantl ~' <br /> <br />-<>-WET (\984) <br /> <br />--ORV(197n <br /> <br />--- AVG <br /> <br />"'*" 2001 <br /> <br />r- <br /> <br />r- <br /> <br />REPRESENTAllVERESER\.ORS <br /> <br />o <br /> <br /> <br />GreEln M1naln A.Jld <br /> <br />~Fok <br />r.l11fJO'OO Cl:J1lI!ItI; <br /> <br />~ - <br /> <br />IIAvg. 11130 Ca1tenIs <br /> <br />" <br /> <br />( <br /> <br />.;1::- <br />
