<br /> <br />PLATTE RIVER BASIN <br /> <br />06707500 SOUTH PLATTE RIVER AT SOUTH PLATTE, CO <br /> <br />LOCATION.--Lat 39°24'33", long 105°10'10", SE¼ sec. 25, T.7 S., R.70 W., Jefferson County, Hydrologic Unit <br />10190002, on left bank at South Platte, 200 ft downstream from bridge on State Highway 75, and 400 <br />ft downstream from North Fork. <br /> <br />DRAINAGE AREA AND PERIOD OF RECORD.--2,579 mi²; 1910 to present. <br /> <br />GAGE.-- A graphic water stage recorder and satellite monitoring equipment in a concrete shelter and CMP <br />well. The Sutron 8004 DCP was replaced with an 8210. The primary gage is an electric tape gage <br />mounted on the equipment shelf. The station was rebuilt with a 60” CMP well and concrete shelter in <br />1994. 120-volt electricity was installed in 2001. The cable way was rebuilt in 1995. The gage is <br />on Denver Water Board property. <br />REMARKS.--The primary record is hourly data taken from satellite readings with chart back up. The record <br />is complete. Open water record agrees with the chart to within ±0.02 ft. when pen corrections are <br />applied. The record is reliable except for the following days when ice was thought to have affected <br />the stage-discharge relationship: December 19, 2002 through March 4, 2003, which were estimated <br />using computed inflows from Strontia Springs Reservoir. The record is good for open water <br />conditions. Station maintained and record developed by Michael Garner. <br /> <br />RATING TABLE.--PLASPLCO16 USED FROM 01-OCT-2002 TO 01-OCT-2003 <br /> <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 /> 1 402 249 247 256 205 215 192 312 714 327 282 352 <br /> 2 430 274 252 264 248 211 232 295 619 300 303 526 <br /> 3 363 272 246 275 250 209 269 285 522 285 407 590 <br /> 4 293 232 246 255 256 198 272 282 478 289 392 712 <br /> 5 230 234 260 288 250 224 254 265 524 399 374 691 <br /> 6 222 230 257 268 226 252 228 250 506 393 366 590 <br /> 7 221 232 263 263 215 255 214 273 488 389 402 691 <br /> 8 233 318 266 263 240 257 202 288 459 366 426 750 <br /> 9 269 291 267 254 246 258 202 278 413 323 428 667 <br /> 10 278 289 285 241 270 261 273 329 413 317 379 605 <br /> 11 303 283 291 290 258 264 409 323 422 322 376 595 <br /> 12 305 238 296 266 248 266 391 312 417 397 427 578 <br /> 13 306 248 299 270 271 268 378 237 422 383 415 572 <br /> 14 300 253 306 271 281 248 439 235 431 318 404 578 <br /> 15 262 250 304 255 257 228 369 263 402 369 399 568 <br /> 16 257 240 287 225 247 229 340 308 395 380 396 551 <br /> 17 257 240 282 225 246 231 335 321 399 457 416 549 <br /> 18 286 237 276 227 251 255 329 362 509 508 423 538 <br /> 19 286 231 240 247 247 155 409 346 567 524 451 403 <br /> 20 286 233 221 254 248 159 357 354 478 476 396 399 <br /> 21 286 236 221 251 255 145 298 334 420 458 386 403 <br /> 22 285 234 237 247 250 130 300 356 388 483 396 452 <br /> 23 288 250 293 251 214 141 309 526 374 551 440 546 <br /> 24 288 249 231 248 257 161 309 481 351 450 447 512 <br /> 25 286 251 286 233 259 186 306 498 360 477 489 421 <br /> 26 250 240 272 190 262 199 319 481 360 512 504 412 <br /> 27 253 250 290 170 256 222 343 508 426 430 529 412 <br /> 28 250 262 251 165 232 197 337 589 492 462 583 409 <br /> 29 252 253 264 164 --- 160 341 600 499 445 568 395 <br /> 30 243 250 251 153 --- 160 330 648 505 411 600 419 <br /> 31 244 --- 271 238 --- 172 --- 670 --- 304 652 --- <br /> <br />TOTAL 8714 7549 8258 7467 6945 6516 9286 11609 13753 12505 13456 15886 <br />MEAN 281 252 266 241 248 210 310 374 458 403 434 530 <br />AC-FT 17280 14970 16380 14810 13780 12920 18420 23030 27280 24800 26690 31510 <br />MAX 430 318 306 290 281 268 439 670 714 551 652 750 <br />MIN 221 230 221 153 205 130 192 235 351 285 282 352 <br /> <br />WTR YR 2003 TOTAL 121944 MEAN 334 MAX 750 MIN 130 AC-FT 241900 <br /> <br />MAX DISCH: 870 CFS AT 08:15 ON Aug. 31, 2003 GH 3.82 FT.
