17 <br />PLATTE RIVER BASIN <br /> <br />SOUTH ST. VRAIN CREEK NEAR WARD, CO <br /> <br />LOCATION.--Lat 40°05'27", long 105°30'50" <br /> <br />DRAINAGE AREA AND PERIOD OF RECORD.--14.4 mi²; 1925-27,28-31, 54-73, 1992 to present <br /> <br />GAGE.--Graphic water-stage recorder and satellite monitoring DCP (8200) with shaft encoder in 42-inch diameter <br />corrugated metal pipe shelter and well. DCP is primary record with chart as backup. <br /> <br />REMARKS.--The primary record is hourly satellite data with chart backup. Record is complete and reliable <br />except for the following periods: October 14, 15, 26, 28, 29, 31; November 1, 4, 2003 — stage <br />affected by ice; November 5, 2003 to May 17, 2004 station was closed for winter. The record is fair <br />due to moving rocks in the open control, except for the following days which are estimated and poor: <br />October 14, 15, 26, 28, 29, 31; November 1, 4, 5, 2003; May 17, 2004. Flows above 200 cfs would also <br />be poor due to lack of recent measurements in this range. This is a partial year record, re- <br />established on May 15, 1992 by Division of Water Resources personnel after the USGS dropped <br />publication. Station maintained and record developed by Merlin Friedrichsen. <br /> <br />RATING TABLE.--SSVWARCO10 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 3.5 1.7 - - - - - - 39 129 29 14 <br /> 2 3.6 2 - - - - - - 41 91 27 13 <br /> 3 4.2 2.2 - - - - - - 54 80 26 12 <br /> 4 4 2 - - - - - - 73 71 25 13 <br /> 5 3.8 2 - - - - - - 89 64 25 18 <br /> 6 3.7 - - - - - - - 105 64 25 16 <br /> 7 3.5 - - - - - - - 119 61 24 17 <br /> 8 3.2 - - - - - - - 122 58 23 16 <br /> 9 2.9 - - - - - - - 138 60 21 15 <br /> 10 2.8 - - - - - - - 162 55 19 15 <br /> 11 3.6 - - - - - - - 122 49 19 17 <br /> 12 2.9 - - - - - - - 84 44 18 16 <br /> 13 2.9 - - - - - - - 68 45 17 15 <br /> 14 2.6 - - - - - - - 73 47 16 14 <br /> 15 2.6 - - - - - - - 82 55 15 14 <br /> 16 2.7 - - - - - - - 92 76 15 12 <br /> 17 2.3 - - - - - - 30 102 91 15 12 <br /> 18 1.9 - - - - - - 32 142 84 18 11 <br /> 19 1.8 - - - - - - 49 158 66 38 11 <br /> 20 1.8 - - - - - - 71 116 63 35 12 <br /> 21 1.6 - - - - - - 87 99 58 35 15 <br /> 22 1.6 - - - - - - 83 84 55 31 17 <br /> 23 1.7 - - - - - - 61 67 72 28 16 <br /> 24 1.5 - - - - - - 64 65 72 23 15 <br /> 25 1.5 - - - - - - 63 66 53 21 16 <br /> 26 1.5 - - - - - - 57 71 43 18 15 <br /> 27 1.5 - - - - - - 59 74 40 19 13 <br /> 28 1.5 - - - - - - 70 83 38 20 13 <br /> 29 1.5 - - - - - - 81 83 37 17 13 <br /> 30 1.5 - - - --- - - 62 132 33 14 21 <br /> 31 1.5 --- - - --- - --- 47 --- 31 14 --- <br /> <br />TOTAL 77.2 9.9 - - - - - 916 2805 1885 690 437 <br />MEAN 2.5 .33 - - - - - 29.5 94 61 22 15 <br />AC-FT 153 20 - - - - - 1820 5560 3740 1370 867 <br />MAX 4.2 2.2 - - - - - 87 162 129 38 21 <br />MIN 1.5 - - - - - - - 39 31 14 11 <br /> <br />WTR YR 2004 TOTAL 6820.1 MEAN 18.6 MAX 162 MIN - AC-FT 13530 <br /> <br />MAX DISCH: 183 CFS AT 04:30 ON Jun. 19, 2004 GH 2.79 FT.
