The purpose of this study is to identify the revelant data - such as construction, stream morphology, and trends of tributaries - to the observed chronologic changes in river stage of the Missouri River at the Sioux City, Iowa area during the approximate period of 1954-1974. The causal relationships present for the observed effects are to be determined and recommendations are to be made for any further data requirements. The investigation includes a study of the following data: (a) Missouri River Stage - Discharge Measurements at Yankton, Sioux City, Decatur, and Omaha.
