<br />.;;{'>!: <br /> <br />in <br /> <br /> <br />Floods of June 1965 <br /> <br />South Platte River Basin - Colorado and Nebraska <br /> <br />Torrential rains June 14 to 17, caused floods in the South Platte River <br /> <br />basin in eastern Colorado. The attached tabulation contains provisional re- <br /> <br />sults of indirect measurements of peak discharge and a few peak discharges <br /> <br />determined from stage-discharge relations defined by current-meter mea- <br /> <br />surements. All of these are subject to revision after additional studies are <br /> <br />made, particularly on streams where measurements were obtained at more <br /> <br />than one location. All streams and sites that were investigated are shown <br /> <br />in the tabulation, whether or not computations were complete. Field sur- <br /> <br />veys are completed, and values of peak discharges will be available for all <br /> <br />stations listed. In addition to the data tabulated, much other information, <br /> <br />such as stream cross sections and water-surface profiles, is available for <br /> <br />inspection at the district office, Surface Water Branch of the Geological <br /> <br />Survey at 1455 Ammons Street, Denver, Colo. <br /> <br />A complete report concerning the floods in the South Platte River basin <br /> <br />in Colorado and in western Nebraska will be published when all computations <br /> <br />are complete. <br /> <br />The summer floods in eastern Colorado, were major hydrologic events. <br /> <br />Many previous maxima were exceeded, some several fold. In many in- <br /> <br />stances, alterations of the stream valleys by erosion were greater than any <br />
