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.

Coal Hollow Park, Chillicothe, IL - CAP Section 206

High flow events on the Coon Creek and the unnamed tributary cause erosion on their banks, increasing sediment load and consequently sediment load into the Illinois Waterway.

Dam Safety Program

The purposes of a dam safety program are to protect life, property and the environment by ensuring that all dams are designed, constructed, operated and maintained safely and effectively.

Dredged Material Management Program (DMMP) - Overview

The Dredged Material Management Program (DMMP) evaluates and identifies preferred alternative dredged material placement site(s) using a six-step planning process and, where applicable, a matrix with six evaluation criteria: dredging cost; natural resources; beneficial use of dredged material; recreational resources; cultural resources; and social impacts.

Emergency Response/Recovery Actions - Overview

The Rock Island District is prepared to provide all hazard response and recovery assistance under the authority of Public Law (PL) 84-99 and PL 93-288.

Farm Creek, Illinois

The project includes two dry reservoirs (Fondulac and Farmdale) located on tributary streams to the Illinois Waterway upstream of Peoria, Illinois, providing flood control for East Peoria, Illinois.

Floodplain Management Services (FPMS)

The Floodplain Management Services (FPMS) Program provides a full range of technical services and planning guidance in support of effective floodplain management and flood risk reduction.

GLMRIS Brandon Road

The U.S. Army Corps of Engineers is evaluating 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.

Illinois River Basin Restoration (sec 519,WRDA 2000)

Section 519 of WRDA 2000 authorized: (1) Comprehensive Plan to develop and implement a restoration program, long-term resource monitoring program, and evaluate new technologies and innovative approaches, and (2) construction of critical restoration projects.

Illinois Waterway

The project includes a total of 268 river miles of 9-foot commercial navigation channel from Chicago to LaGrange Lock and Dam, near Beardstown, Illinois; with 8 locks and 7 dams.

Illinois Waterway Consolidated Lock Closures

To maintain reliable navigation and avoid unscheduled long-duration closures on the Illinois Waterway (IWW), the locks need to undergo scheduled major rehabilitation and maintenance.

Illinois Waterway Maintenance Dredging Operations & Maintenance

In order to maintain the 9-foot navigation channel, maintenance dredging is performed at various locations in the reach of the Illinois Waterway in the Rock Island District.

Inland Navigation Design Center (INDC)

The Inland Navigation Design Center Mandatory Center of Expertise (INDC-MCX) is an organization that provides engineering, design, analysis and review services for studies, new locks, new navigation dams, major rehabilitation of existing inland navigation locks and dams, and significant inland navigation lock and dam Operations & Maintenance (O&M) projects.

LaGrange Lock, Illinois Waterway (Major Rehabilitation/Major Maintenance)

LaGrange Lock, located on the Illinois Waterway at river mile 80.2, was put into service in 1939 and is in need of a major rehabilitation of lock concrete, electrical and mechanical systems.

Levee Safety Program

In the Rock Island District, approximately forty thousand people live or work behind levees in the U.S. Army Corps of Engineers’ Levee Safety Program.

National Flood Fight Materiel Center - Overview

Under authority of Public Law 84-99, during flood emergencies the Corps of Engineers may provide tribal, state and local communities with flood fight supplies and equipment.

National Levee Database

The National Levee Database (NLD), developed by the U.S. Army Corps of Engineers (USACE), is the focal point for comprehensive information about our nation's levees.

Peoria Illinois, Riverfront Development (Environmental Restoration)

The principal goal of this project is to improve depth diversity enhancing aquatic habitat in Peoria Lake with ancillary recreational benefits.

Small Boat Harbors

All small boat harbor projects have a local sponsor, usually a municipality.

UMRR Program - IL, IA, MO, MN, WI - Upper Mississippi River Restoration

The UMRR Program was authorized by the Water Resources Development Act (WRDA) of 1986 and continuously authorized by WRDA 1999. The program consists of two primary elements: habitat rehabilitation projects and systemic monitoring and research.

UMRR Program - Rice Lake Complex HREP - LaGrange Pool

Rice Lake is a 6,800-acre backwater complex located 24 miles southwest of Peoria, Illinois. The project lands are state owned and are managed by the Illinois Department of Natural Resources (ILDNR) as a fish and wildlife area. The project goals are to enhance and restore wetland and aquatic habitat.

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.
