25 <br />PLATTE RIVER BASIN <br /> <br />06710500 BEAR CREEK AT MORRISON, CO <br /> <br />LOCATION.--Lat 39°39'11", long 105°11'42, in SE¼SW¼ sec. 35, T.4 S., R.70 W., Jefferson County, Hydrologic Unit <br />10190002, on left bank at Morrison, 180 ft upstream from bridge on State Highway 8 and 0.2 mi upstream <br />from Mount Vernon Creek. <br /> <br />DRAINAGE AREA AND PERIOD OF RECORD.--164 mi². Sporadic, incomplete data Sep. 1881 to Feb. 1902. Good data <br />October 1919 to current year. Monthly data for some periods only. Some early years published as near <br />Morrison, at Starbuck, at Idledale. Water quality data from Oct. 1976 to Sep. 1981. <br /> <br />GAGE.--Stevens A-35 graphic stage recorder and satellite monitoring DCP with telephone access in a 60-inch metal <br />shelter and 48 inch well. A new compound weir was installed on the creek just prior to beginning of the <br />2003 water year. An drop tape from a reference point within the well references all instruments. <br /> <br />REMARKS.--Hourly data is the primary record, taken from satellite monitoring with chart back-up. Accuracy was <br />maintained by 39 visits to the gage. The record is complete and reliable, except for the following <br />periods: Dec. 16-19, 2005, when the DCP and chart both failed; Dec. 6-15, 20, 2005; January 25-28; <br />February 19-21, 2006, when the gage height was ice affected. The record is good except as follows: <br />December 6-20, 2005; January 25-28; February 19-21, 2006, which were estimated and are considered poor; <br />and November 28-December 5, 2005; January 4, 13, 17, 21-24, 29-31; February 1-18, 22-26, 2006; which are <br />fair due to possible ice affect. Station maintained and record developed by Steve Barrett. <br /> <br />RATING TABLE.--BCRMORCO23 USED FROM 01-OCT-2005 TO 30-SEP-2006 <br /> <br /> DISCHARGE, IN CFS, WATER YEAR OCTOBER 2005 TO SEPTEMBER 2006 <br /> MEAN VALUES <br /> <br /> DAY OCT NOV DEC JAN FEB MAR APR MAY JUN JUL AUG SEP <br /> <br /> 1 21 19 8.6 16 13 16 19 19 15 6.8 24 22 <br /> 2 19 20 18 15 13 15 18 19 13 6.8 24 23 <br /> 3 18 20 21 15 12 15 17 18 13 11 23 24 <br /> 4 18 18 15 14 13 16 18 23 12 12 24 20 <br /> 5 19 20 10 16 12 14 21 24 10 17 21 20 <br /> 6 20 16 8.9 14 12 14 22 25 10 18 30 18 <br /> 7 20 22 6.0 15 12 17 21 24 10 34 33 18 <br /> 8 20 20 6.0 15 13 16 18 22 10 72 32 20 <br /> 9 22 20 8.0 15 12 14 19 21 10 186 26 29 <br /> 10 43 18 10 16 11 11 21 24 11 178 22 27 <br /> 11 33 18 12 13 7.7 11 20 21 9.8 104 22 24 <br /> 12 33 19 15 13 13 14 19 19 10 95 23 24 <br /> 13 34 17 18 13 14 13 21 19 9.2 79 25 21 <br /> 14 29 18 18 14 13 12 22 21 8.7 63 29 20 <br /> 15 30 18 15 14 13 14 24 22 7.6 56 30 19 <br /> 16 29 11 12 12 11 13 22 19 10 50 27 21 <br /> 17 26 19 11 9.1 9.2 13 19 20 12 46 24 18 <br /> 18 25 18 10 13 11 14 20 20 8.8 43 24 17 <br /> 19 25 22 10 13 10 18 17 21 9.2 43 37 17 <br /> 20 26 19 11 11 10 14 14 24 7.0 41 42 17 <br /> 21 24 19 15 7.2 11 13 14 24 6.2 57 33 28 <br /> 22 23 19 17 13 11 15 15 23 11 45 30 25 <br /> 23 23 18 19 11 9.6 15 16 26 13 37 26 25 <br /> 24 22 19 18 14 10 14 19 24 9.5 34 24 23 <br /> 25 21 17 17 13 10 19 20 21 8.4 36 25 23 <br /> 26 21 18 17 14 11 19 17 19 8.2 42 31 22 <br /> 27 21 17 16 11 13 16 18 18 11 43 31 22 <br /> 28 20 9.8 17 11 14 17 20 16 9.1 32 26 20 <br /> 29 21 4.4 16 13 --- 20 22 15 7.1 28 24 20 <br /> 30 21 8.0 16 11 --- 21 18 15 7.7 25 23 19 <br /> 31 20 --- 15 12 --- 18 --- 17 --- 23 21 --- <br /> <br />TOTAL 747 521.2 426.5 406.3 324.5 471 571 643 297.5 1563.6 836 646 <br />MEAN 24.1 17.4 13.8 13.1 11.6 15.2 19.0 20.7 9.92 50.4 27.0 21.5 <br />AC-FT 1480 1030 846 806 644 934 1130 1280 590 3100 1660 1280 <br />MAX 43 22 21 16 14 21 24 26 15 186 42 29 <br />MIN 18 4.4 6.0 7.2 7.7 11 14 15 6.2 6.8 21 17 <br /> <br />CAL YR 2005 TOTAL 16752.7 MEAN 45.9 MAX 198 MIN 4.4 AC-FT 33256 <br />WTR YR 2006 TOTAL 7453.6 MEAN 20.4 MAX 186 MIN 4.4 AC-FT 14780 <br /> <br />MAX DISCH: 242 CFS AT 06:00 ON Jul. 9, 2006 GH 7.11 FT.
