This report is a study of the past and present geomorphic features of the reach of the Upper Mississippi River which includes Pools 24, 25, and 26 and the lower reach of the Illinois River. In addition, the report presents the anticipated future geomorphic changes that will result from past, present, and planned future developments of these reaches. The study was based primarily on data collected by the Corps of Engineers, aided with a mathematical model of the river system. On the basis of this study of the past geomorphic changes in Pools 24, 25, and 26 and with the mathematical simulation of future river response, it was concluded that 50 years from now the study area will be essentially as it is today. The present day manner of operation does not have any serious detrimental effects on the geomorphology or hydraulics of the river system in the study area.
