This recommendation was derived by <br />averaging the results of the three data sets. It is our belief that recommendations that fall outside <br />of the accuracy range of the model, over 250% of the measured discharge or under 40% of the <br />measured discharge, may not give an accurate estimate of the necessary instream flow required. <br />Hydrologic Data <br />BLM recommends using USGS gage 07093775 (Badger Creek near Howard, CO) <br />After receiving the cooperating agency's biologic recommendation, the CWCB staff conducted <br />an evaluation of the stream hydrology to determine if water was physically available for an <br />instream flow appropriation. The hydrograph below was derived from data collected by the <br />USGS stream gage for Badger Creek, Lower Station near Howard, CO (ID #07093775), which <br />has a drainage area of 211 square miles (See Gage Summary in Appendix Q. The total drainage <br />area of the Badger Creek Drainage is approximately 211 square miles. The period of record for <br />this gage was 1980 -2003, the period of record used by staff in their analysis was 1980 -2003, or <br />24 years of record.
