Role of Structural Modifications along the Mississippi River on Sediment Transport to Lake Pepin

University of Minnesota/Satish Gupta

The overarching goal of this research is to assess how the installation of wing dams and closing dams might have affected the downstream movement of sediments to Lake Pepin. The specific objective of this study will be to summarize information gathered from the U.S. Geological Survey and Army Corps of Engineers (USACE), various consultants the USACE has used over the years, and published literature. This study will form the basis for additional studies if it appears that wing dam and closing dams significantly reduced the river-flood plain interactions and someway contributed to an increase in sedimentation rate in Lake Pepin.
