One of the major Illinois rivers originates in a neighboring state. The main stem of the river was channelized about 65 years ago, and is considered to be a 'drainage ditch. ' Extensive agriculture has been developed on the floodplains, and the local interests want to maintain this part of the river as a drainage ditch. The lower part of the river in Illinois still flows in its natural pattern of a meandering stream. When the upstream interests decided to clear, snag, and uproot all the vegetation, the downstream interests questioned the impact of such actions: flood peaks and flows; suspended load and bed load; and increased bank erosion. Research was conducted in which hydrologic, hydraulic, geologic, and biological data were collected and analyzed. The research and some of the recommendations are summarized.
