DuPage County Stormwater Management Continues to Monitor River Elevations and Flood Control Facilities Tuesday

DuPage County Stormwater Management continues to operate Fawell Dam (Naperville) Tuesday morning. Late Monday night, gates at the Elmhurst Quarry Flood Control Facility (Elmhurst) and Spring Creek Reservoir (Bloomingdale) were opened, but both flood control facilities have since ceased operation.

Areas in DuPage County have received more than 2 inches of rain Monday evening into early Tuesday morning. This precipitation rose elevations in Salt Creek and the West Branch DuPage River enough late Monday to warrant operation of the three mechanically operated facilities. All smaller, gravity operated facilities also operated.

While no rain is currently forecasted, Stormwater Management staff continues to monitor river elevations in both Salt Creek and the West Branch DuPage River. Salt Creek tends to have a second peak as upper portions of the river flow into the watershed, and staff will operate again if necessary. River elevations in the West Branch DuPage River are still elevated and flood warnings from the National Weather Service remain in place.

Of the 16 flood control facilities DuPage County operates, four larger facilities have mechanical equipment allowing staff to control them according to a predetermined operating plan. The remaining facilities protect the surrounding areas from flooding without human intervention using fixed weirs and natural drainage systems. In total, the facilities have a floodwater storage capacity of nearly four billion gallons.
