    Backlog of Maintenance

    The Major Rehabilitation and Major Maintenance Program for the Locks and Dams on the Mississippi River and Illinois Waterway has been ongoing since 1975. Major rehabilitation consists of reliability or efficiency improvements.
  • Big Creek Remedial Works

    The Big Creek Remedial Works provides protection for parts of Polk City, Iowa, and adjacent Big Creek Valley which are below the full flood pool level.
  • Brandon Road Interbasin Project

    The U.S. Army Corps of Engineers has evaluated potential control options and technologies at Brandon Road Lock and Dam to prevent the upstream Interbasin transfer of Aquatic Nuisance Species (ANS) while minimizing impacts to Illinois Waterway uses and users. This effort has identified a recommended plan. Implementation of the recommended plan requires congressional authorization.
  • Upper Mississippi River and Illinois River Flow Frequency Study

    The current Upper Mississippi River and Illinois River flow frequency study, completed in 2004, was created using a period of record ending in 1998. Since then frequent and record setting major floods have occurred. The flood of 2019 was not only historic with regards to flood heights, but also in its duration. The Mississippi River was above flood stage at Cape Girardeau for 145 days. In addition, many communities between Dubuque, Iowa and St. Louis, Missouri have experienced the majority of their top 10 flood crests in the past 20 years. Significant flooding on the UMR occurred in 2001, 2008, 2011, 2013, 2014, 2018, and 2019. The Illinois River has experienced the same unprecedented flooding. At Peoria, IL (on the IWW), 5 of the 10 highest flood crests have occurred since 1998; including the record crest in 2013.
  • Upper Mississippi River System Hydraulic Model Update

    The development of a standardized and seamless flood risk management hydraulic model for the Upper Mississippi River (UMR) is an essential tool to understanding the risks that currently exist to the river communities and is a critical first step for the development of systemic flood risk management (FRM) strategy.
