DENVER, CO 80203 <br />303.866.3581; www.water.state.co.us <br /> <br />February 1, 2002 <br /> <br />The Surface Water Supply Index (SWSI) for January presents a bleak outlook statewide. With a range of ~ to <br />+4, the basins in Colorado are between a high of -1.9 for the South Platte Basin and a low of -2.8 fotthe Yampa/White <br />Basin. Snowpack is the major component to the SWSI this time of year, and the snowpack for Janu,ary averaged only' <br />58% of normal for the state. The low snowpack for Colorado was recorded in the Rio Grande-Basin at 48% of flormal, the " <br />high was recorded in the Colorado Basin at 70% of normal. Some division 'offices are alerting the pUblic to possible <br />shortages of water this summer through press releases and public meetings. <br /> <br />The SWSllndex developed by this office and the U.S.D.A. Natural Resources Conservation Service is used as an <br />indicalor of mountain-bas~d water supply conditions in the major river basins of the state. It is 'based on $nowp~ck, <br />reservoir storage, and precipitation for the winter period (November through April). During the winter period. snowpack. is . <br />the primary component in all basins except the South Platte basin where reservoir storage is given the most weight. 'The <br />following SWSI values were computed for each of the seven major basins for February 1,2002, and reflect-the,condltions <br />during the month of January. <br /> <br />Basin <br />South Platte <br />Arkansas <br />Rio Grande <br />Gunnison <br />Colorado <br />Yampa/W~ite <br />San Juan/Dolores <br /> <br />-4 <br />Severe <br />Drought <br /> <br />-3 <br /> <br />-2 <br />Moderate <br />Drought <br /> <br />February 1, 2002 <br />SWSI Value <br />-1.9 <br />-2.2 <br />-2.7 <br />-2.3 <br />-2.6 <br />-2.8 <br />-2.6 <br /> <br />Change From <br />Previous Month <br />-0.3 <br />-0.4 <br />-0.6 <br />-2.9 <br />-1.3 <br />-1.0' <br />-1.0 <br /> <br />Change From <br />Previous Year <br />-LO <br />-0.7 <br />-3.5 <br />-0.5 <br />-0.3 <br />-0.8 ' <br />-2.0 <br /> <br />-1 <br /> <br />Scale <br />o <br />Near Normal <br />Supply <br /> <br />4 <br />Abundant <br />Supply <br /> <br />1 <br /> <br />2 <br />Above Normal <br />Supply , <br /> <br />3 <br /> <br />ReCElveo <br />I-tB 2'0 2002 <br />CoIomdo Water ConS6lVallon Beard <br /> <br />i". <br /> <br />.i", <br />.;. > <br />1~ <br /> <br />
