• <br /> r. <br /> COLORADO BASIN <br /> Basinwide Conditions Assessment: <br /> The SWSI value of+2.0 indicates that for September the COLORADO RIVER BASIN <br /> basin water supplies were above normal. Storage in Green s surface+�`-c Svvly InOsx NI.LGry <br /> Mountain, Ruedi, and Williams Fork reservoirs totaled 115% of 4 <br /> normal on September 30. Flow at the gaging station, Colorado 7.'_ JW3River near Dotsero, averaged 1,338 cfs as compared to the 1961- x ` • = = <br /> 1991 September average of 1,421 cfs. The National Weather -M <br /> Service reports September precipitation as 95% of normal. 1 1 "` <br /> g a .. tiF--r-- _•-ili <br /> Outlook Yl <br /> Substantial rains in September boosted the flows on the a _2 l ti f <br /> Colorado and Roaring Fork rivers and it appears that they will o <br /> maintain their flows throughout the fall season. 3 <br /> JAN84 JAN85 JAN96 JAN87 JAN98 JAN80 JAN90 JAN9, JAN92 JAN93 <br /> Administrative/Management Concerns www,..R <br /> The major water right on the Colorado, the Shoshone <br /> Hydroelectric Power Plant,initiated its 1-17-1929 call of 1,250 cfs <br /> on August 22. This call is usually placed in July or early August. <br /> On September 17,due to the precipitation and increased flows,the <br /> power plant call was reduced to the junior right of 158 cfs (5-15- COLORADO RIVER NR. DOTSERO <br /> FLOW BY WATER YEAR <br /> 1929). Most water rights, transmountain diversions, storage 3.2 <br /> rights, etc. that were junior to the power plant were curtailed. 2.9 <br /> Releases from Green Mountain Reservoir were make to satisfy the 2.6 <br /> call. Very little water has been released from Green Mountain , z.4 <br /> reservoir this year and it remains almost full, as do most of the e^ 2 <br /> other reservoirs in the basin. The Cameo call above Grand ;o c <br /> Junction will likely remain off this year. 1 1.4 <br /> 1 1.2 _ <br /> Public Use Impacts I 09 Z"----'---------7 <br /> The full reservoirs and strong river flows have provided 0.6 J,-----r �r <br /> 0.4 <br /> excellent recreational opportunities this summer,and good supplies 0.2 . <br /> of irrigation water for farmers and ranchers.
