<br />Acmy Cocps of Engineecs, Omaha Distcict foe the South Platte <br />Rivec, Aftec an in depth evaluation of these studies and the <br />available cevisions all available hydcology and hydcaulics <br />appeac to be compatible despite the obvious disccepancies <br />between dischacges and dcainage aceas cepocted in the ociginal <br /> <br />Flood Insucance Studies. <br /> <br />In addition. the Cocps of Engineecs in coopecation with the <br /> <br /> <br />CWCB pcepaced a flood cepoct entitled, "Post Flood Repoct, <br /> <br /> <br />South Platte Rivec and Tcibutacies, May-June 1973, Volumes I <br /> <br /> <br />and II" dated July 1974. The cepoct documents the 1973 flood, <br /> <br /> <br />The 1973 flood outline agcees vecy closely with the 100-yeac <br /> <br /> <br />floodplain contained hecein. This is as expected since the <br /> <br /> <br />U,S.G,S, cepocted a maximum peak dischacge of 11,000 cfs at the <br /> <br /> <br />Littleton gage on May 6, 1973, <br /> <br />Hydcoloqic Analysis <br /> <br />No new hydcologic analysis was pecfocmed foe this <br />consolidation study. Dischacge information contained in the <br />Flood Insucance Studies foe the South Platte River was provided <br />by the U.S, Army Corp of Engineers, Omaha Distcict. in <br />preliminary form to both Gingery Associates and the Soil <br />Conservation Service, The discharges IIGed considered reservoir <br />operations; therefore, do not necessarily compare for certain <br /> <br />locations with regional curves developed and published in the <br /> <br /> <br />Flood Insurance Studies. The discharges apparently used in the <br /> <br /> <br />Flood Insurance Studies are given in table 2 and reflect <br /> <br /> <br />-4- <br />
