Stormwater Management Operating Flood Control Facilities Saturday

DuPage County Stormwater Management is currently operating the Elmhurst Quarry Flood Control, Wood Dale-Itasca Reservoir (Wood Dale) and Spring Creek Reservoir (Bloomingdale) on Salt Creek and the Armstrong Park Reservoirs (Carol Stream) on the West Branch DuPage River following precipitation throughout the area beginning Thursday. 

Portions of DuPage County received between 2.2 and 4.6 inches of rainfall from Thursday afternoon through Saturday morning. Intense rainfall Saturday morning triggered the operation of four of the five of the County’s major flood control facilities. Fawell Dam (Naperville) on the West Branch DuPage River is not at operational elevation, but it is anticipated later Saturday afternoon. In addition, all the County’s gravity operated facilities are in operation. DuPage County Stormwater Management staff will continue to operate the flood control facilities and monitor stream elevations throughout the weekend as an additional 0.75 to 1.25 inches of rainfall is forecasted through Sunday.

Of the 17 flood control facilities DuPage County operates, 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 six billion gallons.
