McDowell Grove, West Branch DuPage River Habitat Restoration And Hydraulic Improvements Project
Notice to Boaters: Because of flood-control and restoration work along the West Branch of the DuPage River, the river is closed between Warrenville Grove and McDowell Grove forest preserves.
Starting May 2013, the Forest Preserve District of DuPage County and DuPage County Stormwater Management will begin to restore a 3-mile stretch of the West Branch of the DuPage River, including 2 miles within McDowell Grove Forest Preserve in Naperville. This project is part of the greater West Branch DuPage River Corridor Restoration Project. The project, funded in part by a $1.37 million grant from the Illinois Environmental Protection Agency, will be completed December 2016. McDowell Grove and its trails will remain open during most of the work, but visitors should be careful near construction areas and follow all signs and workers’ instructions.
Improvement work will include the removal of woody and herbaceous invasive species through the use of herbicides, controlled burning, supplemental seeding and planting and installation of river habitat including riffles and pools. Maintenance of these newly restored areas will commence after project completion. When completed, the project will benefit native wildlife by improving in-stream habitat and enhancing native riverbank and floodplain vegetation. Work along the McDowell Grove floodplain will help homeowners, too, by removing invasive trees and shrubs that will allow the area to better receive and transport stormwater, providing additional protection against localized flooding. To further reduce the risk of flood-related damage, DuPage County Stormwater Management will also be constructing a flood control berm with a multi-use path along the east side of River Road, as well as additional flood control improvements between Warrenville and Diehl Roads that will increase stormwater storage and transport capacities.
