Upper Mississippi and Illinois Rivers Experiencing Widespread and Regional Changes

The U.S. Army Corps of Engineers, Rock Island District; and the U.S. Geological Survey, in partnership with others, have released a report regarding the Ecological Status and Trends of the Upper Mississippi and Illinois Rivers. The Status and Trends report is the third of its kind produced as part of the Upper Mississippi River Restoration (UMRR) program and includes information on long term changes in water quality, aquatic vegetation and fish from six study areas spread across the Upper Mississippi and Illinois Rivers. The report also summarizes trends in possible drivers of long-term changes in the river including river discharge and floodplain land cover.

Upper Mississippi River System Hydraulic Model Update Complete

The U.S. Army Corps of Engineers, Rock Island, St. Paul and St. Louis Districts recently completed a seven-year effort to develop an updated, standardized hydraulic model for the Upper Mississippi River System, including the Illinois Waterway. The model can be used to evaluate and communicate the effects of floodplain modifications to provide better predictability and more consistent flood risk management for the Upper Mississippi River System.
