The U.S. Army Corps of Engineers (USACE) recently completed a feasibility study for the Upper Mississippi River-Illinois Waterway, one of the longest and most complicated studies in its history. The first two reports by this National Research Council (NRC) Water Science and Technology Board committee reviewed analytical aspects of the feasibility study. This report addresses the broader issue of managing the multiple resources of the Upper Mississippi River and Illinois Waterway in light of several, recently-issued NRC reports on USACE planning procedures.

The U.S. Army Corps of Engineers (USACE) recently completed a feasibility study for the Upper Mississippi River-Illinois Waterway, one of the longest and most complicated studies in its history. The first two reports by this National Research Council (NRC) Water Science and Technology Board committee reviewed analytical aspects of the feasibility study. This report addresses the broader issue of managing the multiple resources of the Upper Mississippi River and Illinois Waterway in light of several, recently-issued NRC reports on USACE planning procedures. The committee finds that a key problem is the ambiguity of several pieces of legislation and acts that govern river management and recommends that the administration and Congress clarify the federal intent for management of this river and waterway system. The report also recommends (1) that an independent, retrospective review be conducted of the work of the federal interagency principals group, which was established to provide guidance for the USACE study and (2) that USACE strive to incorporate flexible, adaptive management principles throughout its water planning program, including planning operations of the lock and dam system.
