However, a Corps of Engineers project of stream channel- <br />i zat i on and improvement has been authori zed and funded for the reach up- <br />stream of Oxford Avenue. It is not expected that this project will have any <br />effect on flood flows in the study area. <br /> <br /> <br />HISTORY OF FLOODING <br />Major floods on the South Platte River and its tributaries have been ob- <br />served and recorded since 1844. <br /> <br /> <br />The most significant floods of recent times on the South Pl atte River oc- <br />curred in 1921, 1933, 1942, 1949, 1957, 1965, and 1973. High peak flow <br />floods are most often associated with thunderstorms and sustained rains. <br />Long duration flooding is most often associated with snow melt. Some signi- <br />ficant past floods are described below. <br /> <br />DENVER <br /> <br />~~ <br />Or <br />.
