A bank-operated cableway was added in 1997 for <br />intermediate flow measurements. <br /> <br />REMARKS.--The primary record is hourly data, taken from satellite monitoring with chart back-up. Hourly GH <br />values were taken from the chart on the following days when correct hourly values were not reported <br />via satellite: November 19,25-28; December 4-5; May 5-18; August 1, 12, 17 ,22-24. The Record is <br />complete except for the following periods: December 7, 2001 to March 14, 2002; when station was <br />closed for winter; Sharp changes in the record occur due to diversions through Dille Tunnel (about 1 <br />mile upstream), releases from Lake Estes, and draining/filling of the pond for the City of Loveland <br />power plant. Except for the winter, the record is good due to frequency of measurements & visits and <br />the presence of an artificial control. Record was estimated for December 7, 2001 to March 14, 2002. <br />Record developed and station maintained by Merlin Friedrichsen. <br /> <br />RATING TABLE.--BTCANYCO16 USED FROM 01-OCT-2001 TO 11-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 73 56 38 29 28 26 28 43 87 64 59 38 <br /> 2 79 55 43 29 26 27 29 50 93 67 58 37 <br /> 3 64 54 46 29 26 26 24 56 78 72 56 30 <br /> 4 52 46 34 28 27 26 27 57 87 68 62 42 <br /> 5 68 53 31 29 27 26 28 57 79 62 71 54 <br /> 6 66 57 36 29 26 26 29 55 83 63 84 54 <br /> 7 62 52 35 28 26 26 28 55 64 66 86 54 <br /> 8 59 43 44 28 27 27 28 66 61 65 81 55 <br /> 9 58 42 43 30 27 27 27 86 64 60 88 59 <br /> 10 60 36 33 30 26 27 25 76 77 58 84 59 <br /> 11 57 36 40 29 27 28 29 66 60 59 78 55 <br /> 12 54 35 41 30 27 29 28 69 60 56 76 77 <br /> 13 48 39 37 28 27 29 29 61 65 51 69 93 <br /> 14 45 37 35 28 27 29 28 66 64 58 69 93 <br /> 15 80 33 35 29 28 27 32 65 62 73 65 85 <br /> 16 96 44 44 28 28 28 48 69 67 66 58 84 <br /> 17 101 46 29 28 28 27 52 69 69 59 57 83 <br /> 18 113 59 34 27 28 27 48 98 64 62 54 72 <br /> 19 101 64 32 29 28 26 49 112 66 59 46 53 <br /> 20 109 59 22 27 29 26 52 124 66 63 45 49 <br /> 21 116 64 30 26 28 26 50 162 62 61 44 48 <br /> 22 120 52 31 27 30 26 48 215 60 67 43 45 <br /> 23 127 40 29 26 29 27 45 208 59 80 44 41 <br /> 24 133 38 28 28 29 25 39 177 59 88 46 44 <br /> 25 132 36 30 28 29 25 37 156 58 92 45 41 <br /> 26 110 45 30 28 28 27 36 148 60 92 43 45 <br /> 27 141 34 29 29 27 28 41 147 60 89 45 44 <br /> 28 123 21 28 28 27 29 46 148 63 78 42 53 <br /> 29 107 33 29 27 --- 28 47 158 65 65 42 51 <br /> 30 87 40 29 27 --- 28 40 183 61 63 42 48 <br /> 31 65 --- 27 28 --- 28 --- 121 --- 62 41 --- <br /> <br />TOTAL 2706 1349 1052 874 770 837 1097 3223 2023 2088 1823 1686 <br />MEAN 87 45 34 28 28 27 37 104 67 67 59 56 <br />AC-FT 5370 2680 2090 1730 1530 1660 2180 6390 4010 4140 3620 3340 <br />MAX 141 64 46 30 30 29 52 215 93 92 88 93 <br />MIN 45 21 22 26 26 25 24 43 58 51 41 30 <br /> <br />WTR YR 2002 TOTAL 19528 MEAN 53.5 MAX 215 MIN 21 AC-FT 38730 <br /> <br />MAX DISCH: 266 CFS AT 06:30 ON May. 31, 2002 GH 3.08 FT.
