10 <br />06709610 SOUTH PLATTE RIVER BELOW CHATFIELD RESERVOIR, CO <br /> <br />LOCATION.--Lat 39°33'26", long 105°03'27", SE¼, sec. 1, T.6 S., R.69 W., Jefferson County, Hydrologic Unit <br />10190002. <br /> <br />DRAINAGE AREA.--3,018 mi². <br /> <br />GAGE.--Steven’s A-70 Graphic water-stage recorder with satellite telemetry with electric drop tape for <br />reference. <br /> <br />REMARKS.--The primary record is hourly satellite data and mean daily data from the chart. Daily max and <br />min values agreed with the corrected chart values to within +-0.02 ft. The control was cleaned of <br />moss for most measurements—one correction of –0.01 ft. was observed on October 13, 2000 and was <br />applied by to October 1 as a datum correction. Also, a +0.01 GH correction required (but missed) on <br />the January 5 visit was prorated to the previous and following visits. The record is complete and <br />reliable. The record is good. Station maintained and record developed by Robert E Cooper. <br /> <br />RATING TABLE.--PLACHACO03 USED FROM 01-OCT-2000 TO 30-SEP-2001 <br /> <br /> DISCHARGE, IN CFS, WATER YEAR OCTOBER 2000 TO SEPTEMBER 2001 <br /> MEAN VALUES <br /> <br /> DAY OCT NOV DEC JAN FEB MAR APR MAY JUN JUL AUG SEP <br /> <br /> 1 67 6.2 13 67 11 45 58 28 88 249 111 52 <br /> 2 43 6.2 14 54 11 53 58 28 4.5 418 67 16 <br /> 3 6.8 6.2 14 43 10 59 54 68 4.4 374 104 3.9 <br /> 4 4.7 6.2 7.8 43 10 59 47 99 45 347 117 10 <br /> 5 .59 6.3 .41 43 16 51 42 128 87 306 100 25 <br /> 6 4.6 10 .12 43 21 40 28 153 86 228 138 15 <br /> 7 11 17 .11 43 25 40 19 153 198 241 182 .54 <br /> 8 11 17 .11 43 34 40 19 153 266 236 186 .6 <br /> 9 11 15 .11 43 65 40 11 246 243 194 101 .37 <br /> 10 11 12 .11 43 88 40 .05 325 228 185 97 .28 <br /> 11 11 12 .1 43 88 40 90 323 247 129 192 .23 <br /> 12 11 12 .09 43 99 58 150 243 264 30 193 9.5 <br /> 13 8.8 8.5 .1 43 117 71 81 176 264 56 96 33 <br /> 14 5.6 9.3 .11 43 117 71 23 147 248 142 64 44 <br /> 15 5.6 12 19 43 117 71 22 131 222 161 151 43 <br /> 16 5.6 13 36 43 99 59 29 153 200 64 172 43 <br /> 17 5.6 16 36 43 67 43 38 153 216 96 57 66 <br /> 18 5.6 15 36 43 67 43 38 153 142 89 5.5 98 <br /> 19 7.8 15 35 43 67 43 38 153 77 28 5.5 97 <br /> 20 14 13 39 43 67 43 38 153 107 85 5.4 59 <br /> 21 19 9.6 43 43 67 39 38 142 90 139 5.3 32 <br /> 22 20 9.5 43 43 67 36 38 127 11 120 14 40 <br /> 23 25 9.3 43 43 67 36 77 108 11 133 16 40 <br /> 24 32 10 43 43 67 36 80 96 93 185 .23 40 <br /> 25 32 13 43 43 67 36 42 96 258 212 9.6 40 <br /> 26 24 13 57 31 56 36 42 136 287 213 23 30 <br /> 27 12 20 67 11 46 42 42 212 122 214 26 7.8 <br /> 28 6.5 26 67 11 46 45 42 212 23 127 26 30 <br /> 29 6.5 19 67 11 --- 45 42 146 41 49 43 50 <br /> 30 6.3 17 67 11 --- 50 34 71 114 59 71 .42 <br /> 31 6.2 --- 67 11 --- 59 --- 131 --- 96 125 --- <br /> <br />TOTAL 440.79 374.3 858.17 1196 1679 1469 1360.05 4643 4286.9 5205 2503.53 926.64 <br />MEAN 14.2 12.5 27.7 39 60 47 45.3 150 143 168 80.8 30.9 <br />AC-FT 874 742 1700 2370 3330 2910 2700 9210 8500 10320 4970 1840 <br />MAX 67 26 67 67 117 71 150 325 287 418 193 98 <br />MIN .59 6.2 .09 11 10 36 .05 28 4.4 28 .23 .23 <br /> <br />CAL YR 2000 TOTAL 0 MEAN 0 MAX 0 MIN 0 AC-FT 0 <br />WTR YR 2001 TOTAL 24942.38 MEAN 68.3 MAX 418 MIN .05 AC-FT 49470 <br /> <br />MAX DISCH: 454 CFS AT 10:00 ON Jul. 2, 2001 GH 3.02 FT.
