摘要

Sedimentation severely impacts aquatic habitat along the Illinois River system in Illinois. The problem is especially severe in backwater lakes and the Peoria Lakes that are bisected by the navigation channel. The State of Illinois and the US Army Corps of Engineers, in cooperation with local governments and other organizations, are investigating methods of restoring the river's watershed. Key elements of the developing restoration plan include reducing future sedimentation and removing large quantities of sediment from the backwaters. This paper reports on a pilot project for sediment removal and beneficial use. Sediment mechanically excavated from Lower Peoria Lake is being transported by barge 270 km (168 mi) for use as topsoil. It is being placed on fields at the old US Steel South Works mill bordering Lake Michigan. The site is currently covered with slag and has no topsoil. The area will become part of the Chicago Park District's lakefront park system.
