Peoria Illinois, Riverfront Development (Environmental Restoration)

Published March 10, 2020

Illinois River between Henry and Naples, Illinois with specific focus on Peoria Lake from Illinois River Mile 181.0 to 158.0 and tributaries draining into Peoria Lake.

The recommended plan includes dredging approximately 200 acres within Lower Peoria Lake to create deepwater habitats and constructing three islands with a total area of 75 acres. The principal goal is to improve depth diversity enhancing aquatic habitat in Peoria Lake with ancillary recreational benefits. 

The State of Illinois, Department of Natural Resources, is the sponsor for this project. The feasibility study phase was completed in 2003 and the Pre-construction, Engineering and Design (PED) Phase was initiated in Jan 2004 following receipt of state funding. In September 2004, approval was given to construct the Upper Island (55 acres of dredging with 21 acre island) as a Critical Restoration Project under the Illinois River Basin Restoration Authority (Sec 519, WRDA 2000). The Upper Island construction was completed October of 2013. WRDA 07 authorization will be used to construct the Lower Islands (145 acre dredging with 54 acre islands). 

Pre-construction, Engineering and Design phase was completed for the Lower Islands in December of 2013. WRDA 07 (Section 1001) provided construction authorization for lower islands at a total cost of $24.4M with the cost of inflation. Project is on hold awaiting sponsor and Federal funds.
