8 <br />PLATTE RIVER BASIN <br /> <br />06707501 SOUTH PLATTE RIVER BELOW STRONTIA SPRINGS RESERVOIR, CO <br /> <br />LOCATION.--Lat 39°26'00", long 105°07'30", SW¼SW¼ sec. 16, T.7 S., R.69 W., Douglas County, on right bank <br />1/4 mi downstream from Strontia Springs Dam. <br /> <br />DRAINAGE AREA.--N/A <br /> <br />GAGE.--A Stevens A-70 graphic water stage recorder, satellite monitoring data collection platform with <br />digital shaft encoder installed in a formed concrete shelter. An adjustable reference point with a <br />graduated tape on the float drive for the recorder is used for referencing. An adjustable reference <br />for a drop tape is located below the well manhole. An outside staff gage is used as an additional <br />reference. A new encoder was installed in 2003 that reads to 3 decimal places and allows for <br />tighter calibration. <br />REMARKS.--Record is complete and reliable; no ice conditions were experienced this year. The new encoder <br />maintained calibration so that no corrections were necessary to the record. The record is fair. <br />Station maintained and recored developed by Jana Ash. <br /> <br />RATING TABLE.--PLASTRCO02 USED FROM 01-OCT-2003 TO 30-SEP-2004 <br /> <br /> DISCHARGE, IN CFS, WATER YEAR OCTOBER 2003 TO SEPTEMBER 2004 <br /> MEAN VALUES <br /> <br /> DAY OCT NOV DEC JAN FEB MAR APR MAY JUN JUL AUG SEP <br /> <br /> 1 105 90 85 109 111 38 35 133 55 156 325 158 <br /> 2 138 88 111 115 111 40 36 128 56 148 211 169 <br /> 3 158 88 133 126 104 37 37 123 64 146 145 121 <br /> 4 158 66 137 136 90 38 38 123 67 145 213 85 <br /> 5 156 71 137 180 79 38 38 130 67 98 293 85 <br /> 6 102 90 136 217 61 38 38 136 66 70 388 85 <br /> 7 112 91 136 158 60 38 38 136 66 70 441 85 <br /> 8 138 91 137 168 60 38 39 134 98 70 443 85 <br /> 9 146 91 136 145 61 38 41 75 129 70 386 84 <br /> 10 148 91 136 132 60 38 43 44 189 70 230 85 <br /> 11 119 90 124 131 60 38 44 43 265 71 147 95 <br /> 12 108 90 104 158 53 39 102 43 286 71 148 104 <br /> 13 106 90 97 101 37 39 151 40 242 71 148 103 <br /> 14 104 90 97 47 38 39 151 40 186 70 165 102 <br /> 15 174 90 106 41 41 34 150 56 126 67 133 102 <br /> 16 219 91 120 80 41 32 147 65 70 66 96 86 <br /> 17 219 92 114 126 41 34 147 65 71 67 96 71 <br /> 18 219 93 113 130 40 34 147 68 71 145 128 70 <br /> 19 231 92 113 127 41 34 223 73 143 204 287 70 <br /> 20 237 92 113 124 41 35 180 73 153 258 389 73 <br /> 21 233 93 113 125 41 35 144 68 182 245 297 76 <br /> 22 215 93 114 129 41 35 144 63 195 331 173 77 <br /> 23 170 91 113 126 41 35 184 60 156 533 158 74 <br /> 24 152 91 112 110 40 35 166 57 104 728 147 71 <br /> 25 135 87 111 104 38 35 115 55 70 729 144 71 <br /> 26 118 84 111 119 37 35 136 55 70 511 151 71 <br /> 27 117 84 112 139 36 35 148 55 157 286 163 51 <br /> 28 118 83 125 111 36 35 139 55 323 202 142 37 <br /> 29 119 83 122 97 37 35 135 55 267 234 127 35 <br /> 30 119 84 111 117 --- 33 134 55 175 292 129 35 <br /> 31 111 --- 110 115 --- 44 --- 55 --- 327 137 --- <br /> <br />TOTAL 4704 2640 3639 3843 1577 1131 3270 2361 4169 6551 6580 2516 <br />MEAN 152 88 117 124 54 37 109 76 139 211 212 84 <br />AC-FT 9330 5240 7220 7620 3130 2240 6490 4680 8270 12990 13050 4990 <br />MAX 237 93 137 217 111 44 223 136 323 729 443 169 <br />MIN 102 66 85 41 36 32 35 40 55 66 96 35 <br /> <br /> <br />WTR YR 2004 TOTAL 42981 MEAN 117 MAX 729 MIN 32 AC-FT 85250 <br /> <br />MAX DISCH: 811 CFS AT 15:00 ON Jul. 24, 2004 GH 5.04 FT.
