35 <br />PLATTE RIVER BASIN <br /> <br />MIDDLE ST. VRAIN CREEK NR. PEACEFUL VALLEY, CO <br /> <br />LOCATION.--Lat 40 07’ 55”, long 105 31’ 00”, NE1/4 NW1/4 Sec. 24, T.2 N., R.73 W. <br /> <br />PERIOD OF RECORD AND DRAINAGE AREA.--Gage established on May 14, 1998 by State of Colorado, Division of Water <br />Resources personnel. This gage will be a partial year record station. <br /> <br />GAGE.--Graphic water-stage recorder and satellite monitoring DCP with shaft encoder in 48” diameter metal pipe <br />shelter and well. DCP is the primary record with chart as a backup. <br /> <br />REMARKS.--The primary record is hourly data taken from satellite monitoring with chart back up. The record is <br />complete and reliable except for: November 2, 2004 through May 23, 2005 when the station was closed for <br />the season. The record is good. Flows above 104 cfs are fair due to lack of rating definition. Flows <br />above 200 cfs are fair due to lack of rating measurements. The peak of 313 cfs is considered fair due to <br />lack of confirming measurements at this discharge. This is a seasonal station and is closed during the <br />winter. Station maintained by Merlin Friedrichsen and record developed by Lee Cunning. <br />RATING TABLE.--MIDSTECO04 USED FROM 01-OCT-2004 TO 01-NOV-2004 <br /> MIDSTECO04 USED FROM 23-MAY-2005 TO 30-SEP-2005 <br /> <br /> DISCHARGE, IN CFS, WATER YEAR OCTOBER 2004 TO SEPTEMBER 2005 <br /> MEAN VALUES <br /> <br /> DAY OCT NOV DEC JAN FEB MAR APR MAY JUN JUL AUG SEP <br /> <br /> 1 24 11 - - - - - - 125 112 39 18 <br /> 2 22 - - - - - - - 165 112 53 16 <br /> 3 21 - - - - - - - 158 112 80 16 <br /> 4 21 - - - - - - - 140 108 70 15 <br /> 5 21 - - - - - - - 112 98 67 15 <br /> 6 30 - - - - - - - 114 87 55 15 <br /> 7 26 - - - - - - - 123 87 45 14 <br /> 8 23 - - - - - - - 116 91 39 14 <br /> 9 21 - - - - - - - 114 89 36 15 <br /> 10 20 - - - - - - - 113 88 37 16 <br /> 11 20 - - - - - - - 95 83 39 14 <br /> 12 19 - - - - - - - 97 79 38 13 <br /> 13 20 - - - - - - - 83 82 36 13 <br /> 14 19 - - - - - - - 79 82 36 13 <br /> 15 18 - - - - - - - 103 73 33 12 <br /> 16 17 - - - - - - - 133 72 30 11 <br /> 17 16 - - - - - - - 151 69 27 9.7 <br /> 18 16 - - - - - - - 170 73 26 9.3 <br /> 19 15 - - - - - - - 187 65 24 9.1 <br /> 20 15 - - - - - - - 180 59 24 8.9 <br /> 21 14 - - - - - - - 168 57 25 9.1 <br /> 22 13 - - - - - - - 193 56 25 14 <br /> 23 13 - - - - - - 250 205 55 24 12 <br /> 24 13 - - - - - - 217 192 62 23 11 <br /> 25 13 - - - - - - 197 169 67 24 10 <br /> 26 13 - - - - - - 170 160 69 25 9.5 <br /> 27 12 - - - - - - 154 147 54 23 9.6 <br /> 28 12 - - - - - - 142 130 47 22 20 <br /> 29 10 - - - --- - - 132 122 42 21 15 <br /> 30 12 - - - --- - - 135 111 40 19 14 <br /> 31 13 --- - - --- - --- 136 --- 38 19 --- <br /> <br />TOTAL 542 11 - - - - - 1533 4155 2308 1084 391.2 <br />MEAN 18 .37 - - - - - 49.5 139 75 35 13 <br />AC-FT 1080 22 - - - - - 3040 8240 4580 2150 776 <br />MAX 30 11 - - - - - 250 205 112 80 20 <br />MIN 10 - - - - - - - 79 38 19 8.9 <br /> <br />WTR YR 2005 TOTAL 10024.2 MEAN 27.5 MAX 250 MIN - AC-FT 19880 (PARTIAL YEAR RECORD) <br /> <br />MAX DISCH: 313 CFS AT 21:00 ON May. 23, 2005 GH 3.15 FT.
