16 <br />PLATTE RIVER BASIN <br /> <br />06720500 SOUTH PLATTE RIVER AT HENDERSON, CO <br /> <br />LOCATION --Lat 39°55'19", long 104°52'00", in SE¼NE¼ sec. 34, T.l S., R,67 W., Adams County, Hydrologic <br />Unit 10190003, on right bank 500 ft upstream from bridge on State Highway 22 and 0.2 mi northwest of <br />Henderson. <br /> <br />PERIOD OF RECORD AND DRAINAGE AREA.--4,713 mi². May 1926 to current year. Monthly data only prior to <br />1933. Periodic water quality data available starting in 1955. <br /> <br />GAGE.--Water-stage recorder with satellite telemetry, shaft encoder and Telemark in a 42-inch metal pipe <br />shelter with electric drop tape and outside wire weight as additional reference. An Accubar was <br />installed April 25, 1997 and run in parallel with the shaft encoder. The Accubar is used as primary <br />record during periods of low flows when the well becomes isolated. <br /> <br />REMARKS.--Primary record is hourly readings, taken from satellite monitoring of the stilling well and <br />Accubar with chart back-up on the well. Normally the stilling well record is used, but the well <br />became isolated many days when the stage dropped below about 1.75 ft So this year the Accubar data <br />was used with well data edited into the record spreadsheet for peak flows. The gage height record <br />is complete and reliable. Record is rated as good, except for flows above 831 cfs (including the <br />recorded peak flow) which are fair due to lack of confirming measurements made this year above <br />831cfs. Construction of rock control is planned for this gage in February, 2002, by the Urban <br />Drainage and Flood Control District in cooperation with Colorado DWR and the Metro Wastewater <br />District. Station maintained and record developed by Bob Cooper. <br /> <br />RATING TABLE.--PLAHENCO31 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 /> 1 305 271 251 273 284 344 456 296 817 546 570 405 <br /> 2 286 262 259 276 292 358 373 348 897 682 1030 337 <br /> 3 274 262 256 280 307 365 268 968 799 644 495 316 <br /> 4 278 270 255 285 299 360 265 1730 902 545 426 321 <br /> 5 302 542 244 287 307 354 271 4530 783 604 367 292 <br /> 6 314 480 241 277 302 323 280 2090 645 809 533 287 <br /> 7 315 299 250 275 291 304 318 952 568 682 585 327 <br /> 8 311 283 249 282 279 286 299 774 670 1360 537 969 <br /> 9 311 266 253 276 277 309 307 773 611 2280 589 393 <br /> 10 308 264 255 270 275 382 307 928 480 619 487 262 <br /> 11 304 260 258 269 291 578 1530 997 420 911 626 243 <br /> 12 297 261 249 271 348 519 1320 1020 398 521 459 211 <br /> 13 272 253 245 270 463 407 777 873 950 709 411 209 <br /> 14 245 251 246 264 528 359 555 812 1330 1620 427 249 <br /> 15 241 251 251 271 529 318 520 607 493 725 546 271 <br /> 16 247 250 238 277 574 319 445 520 365 545 498 235 <br /> 17 249 252 240 267 508 326 367 416 307 336 334 237 <br /> 18 257 250 232 281 476 319 355 474 383 320 295 247 <br /> 19 262 251 237 281 466 301 358 405 419 314 257 242 <br /> 20 258 264 243 279 474 296 320 355 467 329 297 240 <br /> 21 256 361 232 281 446 305 348 776 505 423 297 233 <br /> 22 348 359 240 279 377 299 821 369 428 393 323 218 <br /> 23 431 264 247 271 387 315 764 297 464 641 390 213 <br /> 24 287 252 235 271 358 302 645 246 447 846 370 224 <br /> 25 295 252 230 271 354 300 477 227 481 245 351 222 <br /> 26 319 256 255 274 355 466 398 213 659 395 353 254 <br /> 27 314 259 287 279 354 505 352 229 586 498 359 292 <br /> 28 267 252 284 283 359 434 316 347 447 445 310 294 <br /> 29 262 247 282 287 --- 425 309 858 446 358 308 316 <br /> 30 263 249 278 299 --- 484 314 805 446 344 330 322 <br /> 31 274 --- 276 286 --- 491 --- 667 --- 322 405 --- <br /> <br />TOTAL 8952 8493 7798 8592 10560 11453 14435 24902 17613 20011 13565 8881 <br />MEAN 289 283 252 277 377 369 481 803 587 646 438 296 <br />AC-FT 17760 16850 15470 17040 20950 22720 28630 49390 34940 39690 26910 17620 <br />MAX 431 542 287 299 574 578 1530 4530 1330 2280 1030 969 <br />MIN 241 247 230 264 275 286 265 213 307 245 257 209 <br /> <br />CAL YR 2000 TOTAL 0 MEAN 0 MAX 0 MIN 0 AC-FT 0 <br />WTR YR 2001 TOTAL 155255 MEAN 425 MAX 4530 MIN 209 AC-FT 307900 <br /> <br />MAX DISCH: 7080 CFS AT 23:15 ON Jul. 8, 2001 GH 7.88 FT.
