13 <br />PLATTE RIVER BASIN <br /> <br />06714000 SOUTH PLATTE RIVER AT DENVER, CO <br /> <br />LOCATION.--Lat 39°45'35", long 105°00'10", in NW¼SE¼ sec. 28, T.3 S., R.68 W., Denver County, Hydrologic <br />Unit 10190003, on right bank 90 ft Upstream from Nineteenth Street Bridge in Denver and 0.4 mi <br />downstream from Cherry Creek. <br /> <br />DRAINAGE AREA AND PERIOD OF RECORD.--3,861 mi². May 1889 to Oct. 1890 sporadic record. July 1895 to <br />current year continuous. Monthly data only for some periods. <br /> <br />GAGE.--The shelter is 72 inch by 72 inch precast concrete structure with a 48 inch corrugated steel well. <br />The station uses an electric drop tape, Sutron 8210 satellite telemetry with a phone modem interface <br />(303-297-9505), a continuous chart recorder and a supplemental outside wire weight. A city water <br />line is plumbed to the gage for flushing the inlets. The gage and chart recorder are maintained by <br />DWR. The USGS Lakewood Field Office maintains the satellite equipment and phone interface for the <br />USCOE. <br /> <br />REMARKS.--The primary record is hourly data taken from satellite monitoring with chart backup. Daily <br />maximum & minimum stages for the satellite record checked to within ±0.02 with the chart. The <br />record is complete and reliable. The record is considered good, except for August 18 & 19, which <br />are fair due to lack of confirming measurements above 574 cfs since 1999. The yearly peak flow <br />recorded on August 18 is also considered fair. Station maintained and record developed by Jana Ash. <br /> <br />RATING TABLE.--PLADENCO33 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 /> 1 140 91 67 72 117 139 79 682 126 436 475 192 <br /> 2 115 85 65 75 111 132 154 534 193 583 436 192 <br /> 3 106 80 62 81 103 147 612 324 118 353 296 271 <br /> 4 101 73 67 80 111 159 166 325 110 306 309 219 <br /> 5 98 68 70 74 110 292 144 322 133 239 327 215 <br /> 6 93 67 70 70 118 185 378 356 256 231 523 186 <br /> 7 90 68 64 76 135 163 419 346 290 274 570 180 <br /> 8 93 67 78 76 133 160 296 358 202 216 600 165 <br /> 9 87 65 106 77 123 120 431 267 392 411 425 138 <br /> 10 81 69 88 77 117 110 675 260 300 405 520 136 <br /> 11 80 68 74 76 122 109 451 310 252 317 520 132 <br /> 12 92 68 70 78 109 98 538 776 147 295 430 129 <br /> 13 91 67 67 74 98 91 280 683 123 271 322 125 <br /> 14 94 64 80 70 113 96 247 619 114 232 319 147 <br /> 15 97 65 80 80 122 94 205 489 108 164 310 153 <br /> 16 91 72 73 85 123 76 208 196 129 363 223 153 <br /> 17 87 74 84 84 124 72 280 193 229 523 194 137 <br /> 18 82 72 89 85 132 70 292 220 508 820 1500 111 <br /> 19 79 69 87 86 189 81 290 275 596 732 1890 101 <br /> 20 80 67 86 99 237 84 172 200 486 537 648 102 <br /> 21 71 68 84 101 168 86 203 188 559 369 585 319 <br /> 22 72 70 85 92 147 86 362 186 319 302 370 334 <br /> 23 70 81 80 87 140 80 763 279 198 520 383 176 <br /> 24 68 89 78 85 122 74 327 215 161 947 495 179 <br /> 25 77 81 78 87 118 70 226 186 146 991 507 208 <br /> 26 88 69 79 108 111 69 191 160 207 742 335 167 <br /> 27 91 67 81 173 111 62 211 144 519 365 731 212 <br /> 28 82 62 75 122 113 66 279 136 880 451 431 414 <br /> 29 78 66 76 108 193 73 364 137 682 597 359 179 <br /> 30 77 62 73 107 --- 69 638 139 403 509 361 222 <br /> 31 89 --- 72 105 --- 70 --- 138 --- 420 268 --- <br /> <br />TOTAL 2740 2134 2388 2750 3770 3283 9881 9643 8886 13921 15662 5594 <br />MEAN 88 71 77 89 130 106 329 311 296 449 505 186 <br />AC-FT 5430 4230 4740 5450 7480 6510 19600 19130 17630 27610 31070 11100 <br />MAX 140 91 106 173 237 292 763 776 880 991 1890 414 <br />MIN 68 62 62 70 98 62 79 136 108 164 194 101 <br /> <br />WTR YR 2004 TOTAL 80652 MEAN 220 MAX 1890 MIN 62 AC-FT 160000 <br /> <br />MAX DISCH: 6660 CFS AT 22:00 ON Aug. 18, 2004 GH 8.83 FT.
