4 <br /> <br />PLATTE RIVER BASIN <br /> <br />06696000 SOUTH PLATTE RIVER(below Elevenmile Reservoir) NEAR LAKE GEORGE, CO <br /> <br />LOCATION.--Lat 38°54'19", long 105°28'22". in SW¼ sec. 20, T.13 S., R.72 W., Park County, Hydrologic Unit <br />10190001, on left bank 700 ft downstream from Elevenmile Canyon Reservoir and 8.2 mi southwest of <br />town of Lake George. <br /> <br />DRAINAGE AREA AND PERIOD OF RECORD.--963 mi². October 1929 to current year. Monthly data only for some <br />periods. <br /> <br />GAGE.--Water-stage recorder and satellite monitoring in a wooden shelter at a 15' Parshall flume with <br />outside staff gage. Elevation of gage is 8,458 ft from topographic map. Station is owned and <br />maintained by the Denver Water Dept. <br /> <br />REMARKS.--Record is taken from hourly satellite data and is complete and reliable. A number of small <br />encoder corrections were made, including 2 of note: A –0.05 ft correction was made on August 5 and <br />applied back to the last visit on July 24. This correction was made during a period of “painting” <br />record and should be considered less reliable. Also, a datum correction was used for a flume <br />cleaning on May 30 and was applied back to the previous visit May 6. This is also considered a less <br />reliable correction. The record is good, except for May 6-20 and July 24-August 5 which are fair <br />due to corrections made. Record developed by Rodger Burcher. <br /> <br />RATING TABLE.--STD15FTPF USED FROM 01-OCT-2001 TO 07-OCT-2002 <br /> <br /> DISCHARGE, IN CFS, WATER YEAR OCTOBER 2001 TO SEPTEMBER 2002 <br /> MEAN VALUES <br /> <br /> DAY OCT NOV DEC JAN FEB MAR APR MAY JUN JUL AUG SEP <br /> <br /> 1 174 124 121 74 110 60 58 76 41 56 588 182 <br /> 2 183 122 116 75 70 61 52 76 42 60 589 182 <br /> 3 176 125 115 76 75 59 54 79 40 65 505 233 <br /> 4 168 126 110 76 78 59 53 77 41 73 365 328 <br /> 5 158 128 107 78 79 56 52 80 46 80 233 363 <br /> 6 153 129 103 78 77 55 53 79 46 88 198 362 <br /> 7 148 130 98 78 75 55 55 81 45 90 198 360 <br /> 8 144 132 92 78 74 54 55 82 44 88 281 359 <br /> 9 143 136 88 78 70 53 59 76 42 82 473 329 <br /> 10 180 136 84 80 68 52 61 74 36 86 585 213 <br /> 11 205 136 82 81 67 51 62 69 34 96 582 139 <br /> 12 222 136 79 82 65 51 65 68 32 97 583 139 <br /> 13 230 135 77 81 65 51 73 67 29 96 583 118 <br /> 14 215 135 75 80 65 53 76 65 27 96 581 84 <br /> 15 118 134 74 80 68 56 78 62 27 97 567 83 <br /> 16 55 134 74 80 67 60 81 59 26 99 466 122 <br /> 17 57 134 73 79 66 61 78 57 26 100 394 197 <br /> 18 62 133 71 79 65 63 76 56 25 132 393 230 <br /> 19 65 134 72 78 65 65 72 55 23 181 395 230 <br /> 20 73 131 71 79 65 66 75 53 21 235 397 229 <br /> 21 82 130 72 78 63 66 78 57 22 281 397 213 <br /> 22 91 130 72 77 62 66 79 55 23 336 400 203 <br /> 23 97 131 71 76 63 67 78 47 22 391 400 202 <br /> 24 101 128 72 77 62 65 76 48 22 431 402 201 <br /> 25 96 128 72 78 62 68 75 50 23 473 403 201 <br /> 26 99 127 71 77 61 68 78 48 24 526 402 201 <br /> 27 109 123 72 77 61 68 82 45 27 578 351 200 <br /> 28 119 124 72 77 61 65 80 43 38 591 286 201 <br /> 29 124 126 74 107 --- 61 78 41 46 590 199 200 <br /> 30 123 125 74 134 --- 60 78 40 51 589 183 200 <br /> 31 127 --- 74 136 --- 59 --- 40 --- 588 183 --- <br /> <br />TOTAL 4097 3902 2578 2564 1929 1854 2070 1905 991 7371 12562 6504 <br />MEAN 132 130 83 83 69 60 69 62 33 238 405 217 <br />AC-FT 8130 7740 5110 5090 3830 3680 4110 3780 1970 14620 24920 12900 <br />MAX 230 136 121 136 110 68 82 82 51 591 589 363 <br />MIN 55 122 71 74 61 51 52 40 21 56 183 83 <br /> <br />WTR YR 2002 TOTAL 48327 MEAN 132 MAX 591 MIN 21 AC-FT 95860 <br /> <br />MAX DISCH: 601 CFS AT 11:45 ON Jul. 27, 2002 GH 4.28 FT.
