Basically, we have utilized the results <br />of the South Arkansas River/Poncha Creek floodplain study (referred to in <br />this report as previous study) prepared by Water Resources Consultants, <br />Inc. (WRC), and verified that the regional analysis of the stream gage <br />records is also valid for the downstream reach of the South Arkansas River. <br />We are recommending that the discharges listed in Table-3 of this report <br />be used for the South Arkansas River floodplain study. <br /> <br />Please provide us with your input regarding the recommended peak flows <br />for the floodplain study. We would like to receive your approval of the <br />flow values before we proceed with the hydraulic analysis phase of the study. <br /> <br />Very truly yours, <br /> <br />WATER RESOURCES CONSULTANTS, INC, <br /> <br />t \. ~t..)
