"From the Purpose: The purpose of the Comprehensive Plan is to 'develop a plan to address water resource and related land resource problems and opportunities in the upper Mississippi and Illinois River basins,....in the interest of systemic flood damage reduction...' Long-term ecosystem management and sustainability planning also benefits from the development of a systemic conceptual plan for flood risk management. For example, fish and wildlife management, particularly in the lower reaches of the system, depends heavily upon active water level management. Any flood risk management planning could benefit these facilities. The Comprehensive Plan investigated systemic flood risk management plans for the Upper Mississippi and Illinois Rivers. In developing the plans, both structural and nonstructural flood risk management alternatives were considered. In addition, other system needs associated with flood risk management were considered. The Comprehensive Plan was developed as a collaborative effort involving the U.S. Army Corps of Engineers' District at Rock Island, St. Louis, and St. Paul as well as a number of Federal and state agencies and non-governmental organizations." From the Study Area: "The study area encompasses portions of five states--Minnesota, Wisconsin, Iowa, Illinois, and Missouri--extending more than 800 miles along the Mississippi River from Minneapolis-St. Paul downstream to southeast Missouri (below St. Louis), and along 200 miles of the Illinois River downstream from (but not including) the metropolitan Chicago area to the confluence with the Mississippi River."
