<br /> <br />PLATTE RIVER BASIN <br /> <br />06754000 SOUTH PLATTE RIVER NEAR KERSEY, CO <br /> <br />LOCATION.--Lat 40°24'44", long 104°33'46", in NW¼SW¼ sec. 9, T.5 N., R.64 W., Weld County, Hydrologic Unit <br />10190003, on downstream side of bridge on State Highway 37, 1.9 mi north of railroad in Kersey, and <br />2.5 mi downstream from Cache la Poudre River. <br /> <br />DRAINAGE AREA AND PERIOD OF RECORD.--9,659 mi². May 1901 to Dec. 1903, Mar. 1905 to current year. Monthly <br />totals only for some periods. Periodic water-quality data available from 1950. <br /> <br />GAGE.--A graphic water-stage recorder and digital shaft encoder activated by a manometer in a concrete <br />block shelter, also equipped with a satellite monitoring DCP. Both devices are hooked to the <br />manometer. An outside wire weight is used for referencing the gage. A land-line phone is installed <br />and the DCP is equipped with a voice modem card. <br /> <br />REMARKS.--The primary record is hourly data taken from the manometer. The manometer-encoder tracking was <br />checked by comparison to chart mean gage heights. Satellite data checked against the chart to ±0.02 <br />ft. Record is rated fair due to manometer operation and channel instability. The estimated <br />periods, March 19-20, 24-31 April 24-26, May 11 should be considered poor. For complete station <br />break down, see original record at Division Office. Station maintained and record developed by <br />George Sievers. <br /> <br />RATING TABLE.--PLAKERSH01 USED FROM 01-OCT-2002 TO 01-OCT-2002; PLAKERCO22 USED FROM 26-NOV-2002 TO 14-MAR- <br />2003; PLAKERSH02 USED FROM 14-MAR-2003 TO 11-MAY-2003; PLAKERSH03 USED FROM 11-MAY-2003 TO 06-AUG-2003; <br />PLAKERCO22 USED FROM 06-AUG-2003 TO 29-AUG-2003; PLAKERSH04 USED FROM 29-AUG-2003 TO 31-AUG-2003; <br />PLAKERSH05 USED FROM 01-SEP-2003 TO 01-OCT-2003 <br /> <br /> DISCHARGE, IN CFS, WATER YEAR OCTOBER 2002 TO SEPTEMBER 2003 <br /> MEAN VALUES <br /> <br /> DAY OCT NOV DEC JAN FEB MAR APR MAY JUN JUL AUG SEP <br /> <br /> 1 187 574 482 502 598 586 580 782 4040 392 224 2350 <br /> 2 190 563 476 477 585 604 551 748 4330 389 199 1160 <br /> 3 346 558 476 465 589 624 534 581 3790 359 194 873 <br /> 4 492 567 464 477 628 634 502 500 3050 341 189 808 <br /> 5 455 583 464 466 674 614 463 429 2730 268 178 678 <br /> 6 369 572 450 465 634 618 444 354 2470 201 173 571 <br /> 7 322 569 442 466 595 603 392 274 2200 194 160 509 <br /> 8 321 566 436 467 593 581 378 218 2480 221 166 488 <br /> 9 300 558 437 454 614 546 345 204 1730 209 161 501 <br /> 10 293 559 435 444 599 527 337 671 1190 158 243 469 <br /> 11 285 561 423 433 604 515 376 2880 1090 159 195 443 <br /> 12 265 563 430 437 601 507 390 2440 1240 159 171 424 <br /> 13 265 562 444 456 593 499 412 1620 1310 160 184 427 <br /> 14 271 556 440 470 603 481 378 1150 1240 155 169 425 <br /> 15 279 540 440 514 606 449 288 943 1210 141 156 429 <br /> 16 297 535 449 510 610 434 366 869 1210 145 147 422 <br /> 17 307 537 455 522 620 442 485 1030 1200 149 142 411 <br /> 18 326 535 468 526 582 553 518 845 1490 144 141 457 <br /> 19 300 530 454 531 574 760 486 815 2520 173 163 470 <br /> 20 286 526 449 541 563 820 636 850 2070 336 195 444 <br /> 21 280 518 459 539 548 916 600 789 1730 229 161 439 <br /> 22 290 515 455 540 536 926 481 678 1460 184 154 435 <br /> 23 311 516 456 521 538 1040 703 538 1200 171 141 432 <br /> 24 329 505 449 549 530 1440 1240 442 1030 174 137 413 <br /> 25 346 518 430 552 542 1370 2400 505 916 163 132 382 <br /> 26 362 535 410 554 582 1090 1290 513 871 155 144 357 <br /> 27 416 552 453 566 587 1080 871 587 687 167 142 341 <br /> 28 391 546 510 583 592 1150 711 645 485 184 137 325 <br /> 29 451 551 513 595 --- 980 602 1080 370 217 157 301 <br /> 30 510 515 503 583 --- 820 649 1660 352 205 307 279 <br /> 31 596 --- 508 591 --- 680 --- 2830 --- 290 1840 --- <br /> <br />TOTAL 10438 16385 14160 15796 16520 22889 18378 28470 51691 6592 7002 16463 <br />MEAN 337 546 457 510 590 738 613 918 1723 213 226 549 <br />AC-FT 20700 32500 28090 31330 32770 45400 36450 56470 102500 13080 13890 32650 <br />MAX 596 583 513 595 674 1440 2400 2880 4330 392 1840 2350 <br />MIN 187 505 410 433 530 434 288 204 352 141 132 279 <br /> <br />WTR YR 2003 TOTAL 224784 MEAN 616 MAX 4330 MIN 132 AC-FT 445900 <br /> <br />MAX DISCH: 4690 CFS AT 05:00 ON Jun. 2, 2003 GH 7.14 FT.
