• <br />~J <br />• <br />USGS stream gage for Con Creek above New Castle, CO ()09085200), which has a <br />drainage area of 23.8 square miles (See Gage Summary in Appendix C). The total drainage area <br />of the Canyon Creek Drainage upstream of the Baxter Ditch is approximately 18.7 square miles. <br />The period of record for this gage was 1969 to 1986, the period of record used by staff in their <br />analysis was 1969 to 1986, or 17 years of record. Table 2 below displays the flow of Canyon <br />Creek upstream of the Baxter Ditch #1 (Table 2), in terms of a percentage of exceedence. <br />Table ?: Canyon Creek estimated flow upstream of Baxter Di[ch. <br />CenyDn Ck us of eazler OipN <br />EaceeEences Janua Februa Mamb ril Ma June Jul Pu usI Se iember October November December <br />IM <br />5% <br />10% <br />20% <br />50% <br />BO% <br />90% <br />95% <br />99% <br />14.14 14.14 19.64 10).]3 390.Od 5]656 39545 460] 30.64 43.65 22.)1 1].29 <br />1346 12.5) 16.50 5693 32222 44]Bfi 1654) 29.06 206J 33.00 2043 15)1 <br />II5] 11.)9 14.9] 44]9 26306 3fifi.14 104.03 25.14 10.06 2483 18.86 14.93 <br />125] iV9 12.10 2906 20821 J160T 6]]3 2121 16.50 2121 R29 14.14 <br />9.43 9.43 1021 15.)1' 92.)1 196.]9 J3 ]9 ~t5.)1 12.5] 14.83 13]6 11 d0 <br />].06 ].B6 B.fid 11.00 5029 92)1 22.00 1100 1021 1021 943 854 <br />].46 ]d6 ].06 1021 31.43 53 d3 1650 0.64 943 8.W 8.64 ]B6 <br />].31 ]J5 ]B6 9J3 18.86 36,93 1336 605 6.13 ].B6 6.52 )23 <br />680 632 ]1] 664 15]1 1650 ]56 460 5fi9 6A6 6.13 6.95 <br />Canyon Creek Estimated Stream Flow <br />u/s of the Baxter Ditch <br />30 <br />25 - ,. . -_ .. - <br />20 ------ - --- - <br />15 ---- ------ - - --- --- -- <br />10 - --- __- - - --------_- <br />5 <br />0 <br />JAN F® MAR APR MAY JUN JUL AUG SFP OCT NW OK <br />Month <br />Table 2 above shows that the summer recommendation of 24.1 cfs is available May 15 through <br />July 14`".
