Flood control facilities in DuPage operating following heavy rains

Salt Creek in eastern DuPage County

DuPage County Stormwater Management is currently operating all of its major flood control facilities, as well as several smaller, gravity-operated flood control facilities, following rainfall over the weekend.

DuPage County received 2.5 to 3.5 inches of rainfall countywide over the past 48 hours with an additional ¼ of an inch forecasted through Monday.

This precipitation raised elevations in Salt Creek and the West Branch DuPage River enough to trigger operation of the County’s large flood control facilities, including the Elmhurst Quarry, Wood Dale-Itasca Reservoir, Fawell Dam (Naperville), Spring Creek Reservoir (Bloomingdale) and the Armstrong Park Reservoirs (Carol Stream).

Of the 16 flood control facilities DuPage County operates, these five 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.

DuPage County Stormwater Management staff will continue to monitor stream elevations and provide updates as they become available.
