Illinois River Basin Restoration (sec 519,WRDA 2000)

Published March 10, 2020

Entire Illinois River Basin including tributaries.

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. Section 519 and the related Illinois River Ecosystem Restoration Feasibility Study, Sec 216, resulted in a joint Comprehensive Plan for the restoration of the basin. These efforts relate to the State's Illinois Rivers 2020 initiative, a proposed 20-year, Federal-state effort to restore and enhance the 30,000 square-mile Illinois River Basin. Anticipated benefits include reducing sediment delivered to the Illinois River mainstream and backwaters, reducing streambank erosion and improving critical habitats for fish, waterfowl and other aquatic organisms. This project involves three districts (Rock Island, St. Louis, and Chicago).

Construction of the following projects were completed: Peoria Upper Island project was completed in October of 2013 and Waubonsie Creek Critical Restoration Project was completed in November 2011. Construction of the Blackberry Creek Fish Passage project was completed by the State of Illinois in 2012. The Comprehensive Plan was approved by HQUSACE in May 2007. In 2008 the Comprehensive Plan was approved by the ASA for Civil Works and OMB. The Comprehensive Plan and cover letters were sent to Congress.

Three construction projects (Pekin Lake North, Pekin Lake South Backwater and Starved Rock) are on hold pending federal funding.  Feasibility studies Fox River and Tenmile Creek are on hold pending sponsor funds.
