SOUTH PLATTE BASIN <br /> Basinwide Conditions Assessment: <br /> The SWSI value of 1.9 indicates that for October the SOUTH PLATTE RIVER BASIN <br /> )asin water supplies were above normal.' Reservoir storage, s ''.�tK 51�p1y "`.torY - <br /> the key component in this basin in computing the SWSI value, 4 <br /> was 99% of normal on October 31. Storage in the major W 3 . . ;; ;., <br /> plains reservoirs, Julesburg, North Sterling, and Prewitt, - - :�-- ,,;. t l : l' . <br /> 2 increased by 23,567 acre-feet during October and are at 28% -= a <br /> of capacity. Storage in the major upper basin reservoirs, i 1 `� <br /> Cheesman, Eleven Mile, Spinney, and Antero, decreased by i ° - -- 1 - '"'-' <br /> 6,593 acre-feet and are at 84% of capacity. The mean daily Ti <br /> riff <br /> flow of the South Platte River at the Kersey gage was 607 cfs, . <br /> a -2 <br /> as compared to the 1961-1993 October average of 840 cfs. o <br /> Flow at the Colorado/Nebraska state line averaged 151 cfs. -3 <br /> The National Weather Service reports basin precipitation as -4 <br /> JANBS JANOS JAN97 JAN99 JANB9 JAN90 JAN91 JAN92 JAN93 JAN94 <br /> 140% of normal during the month. MONTH/YEAR <br /> While flow conditions continued to be below normal <br /> during October, limited grass hay and alfalfa.irrigation did <br /> occur, assisted by late season precipitation. Recharge and <br /> some storage also continued during the month. <br /> Despite the low stream flows there was not a formal SOUTH PLATTE RIVER NR. KERSEY <br /> call on the South Platte below Chatfield Reservoir during 9° FIRST MINN of THE NATER YEAR <br /> much of the month. The only call on the lower reach was for <br /> recharge at the end of the month. As is usually the case, ,.-j <br /> Denver had a call on the upper reach of the South Platte all <br /> of October. <br /> si <br /> Administrative/Manazement Concerns g <br /> The primary administrative concern at this time is <br /> z° <br /> filling the irrigation reservoirs which were depleted during the <br /> dry summer. There is some question whether these reservoirs 1° <br /> will reach their normal winter storage levels prior to the4 <br /> delivery canals being frozen out. If they do not reach normal ° A <br /> 1961-19113 OCTOBER AVERAGE OCTOBER 1994 <br /> winter levels, good stream flows will be required next spring <br /> in order to fill the reservoirs. <br /> Meetings were held during October between <br /> interested parties concerning the Platte River endangered <br /> species program. These discussions included representatives <br /> from the U.S.Fish and Wildlife Service,other federal agencies, Representative Reservoirs <br /> Colorado, Wyoming, and Nebraska. The intent of the 240 South <br /> Platt'River Basin <br /> discussions is to devise a basin-wide program that addresses 22° 7 <br /> the needs of both the central Platte River endangered species 2O0 <br /> and Platte River water users. t 190 /�/��\ <br /> ii 12O-/� <br /> h r 100 yN <br /> 40 /" 77 <br /> 2°- -\\/\ // &\ 7- <br /> Dillon Horwtooth Eleven Mlle Charmer' Jackson Barr Lake <br /> ® A.Q. 10/31 Contents ® la/31/94 Content. <br /> 3 <br />
