The Starved Rock Breakwater project is a habitat restoration effort to restore submerged aquatic vegetation in the Illinois River, Starved Rock Pool. It was designed to increase the amount and quality of resting and feeding habitat for migratory waterfowl and improve spawning and nursery habitat for native fish.
Construction of the breakwater involved placement of riprap along northern edge of the former Delbridge Island, adjacent to the navigation channel between River Mile 233 and 234. The breakwater structure is approximately 6,100 feet in length and constructed to an elevation of 461.85 feet, providing adequate protection to allow for submerged aquatic vegetation growth.
