The potentially responsible parties (PRPs) have removed the beaver dams and have collected the sediment samples they need for treatability studies. The treatability studies will establish the correct silt fence to minimize releases of sediment during the actual dredging to occur this fall. The studies will also determine the types and amounts of materials (lime, kiln dust, fly ash, etc.) required to stabilize the sediment, chemically tie up the metals and insure the sediment mixture will bear the weight of the cap on the Interim Storage Cell where the sediment will be placed. The Illinois Environmental Protection Agency (Illinois EPA) anticipates work to be completed by late fall or early winter 2004, if lake and river levels that affect the South Ditch are at their normal seasonal levels.

Village of Rosemont special project report : Willow-Higgins Creek Flood Mitigation Project phases III & IV, Cook County, Illinois.

Report by the Illinois Office of Water Resources on Phases III & IV of a flood hazard mitigation project in Rosemont, Illinois. Phase III of the Willow-Higgins Flood Mitigation Project consists of widening and improving a 340-foot reach of Willow-Higgins Creek upstream of River Road. The improvement will include the replacement of 340 lineal feet of vertical floodwall along both sides of Willow-Higgins Creek. Phase IV of the Willow-Higgins Flood Mitigation Project consists of widening and improving a reach of Willow-Higgins Creek between the downstream end of Phase II, which is 2565 feet downstream of Higgins Road, and Granville Road; and also between Willow Creek Road and a point 160 feet downstream of Willow Creek Road.

Yorkville/Glen Palmer Dam alternative analysis and preliminary design project OWR-02-003 : Yorkville, Illinois, Kendall County.

This executive summary report summarizes the results of an alternative evaluation and preliminary design study for improvements to, or removal of, the Glen D. Palmer Dam in Yorkville, Illinois. This study was conducted to recommend the best method of improving the hydraulic conditions at the downstream face of the dam, reconnect the river with respect to fish movement, and provide safe canoe passage through the dam site. The recommended alternative was developed by working with a Citizen Advisory Committee to involve the public throughout the study.
