Stormwater Management Operating Flood Control Facilities Early Friday

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 Fawell Dam (Naperville) and the Armstrong Park Reservoirs (Carol Stream) on the West Branch DuPage River following precipitation throughout the area beginning Thursday through early Friday morning. 

Portions of DuPage County received between 2.8 and 4.1 inches of rainfall from early Thursday morning through early Friday morning. Intense rainfall overnight triggered the operation of the County’s major flood control facilities. 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 day Friday. Little to no rain is forecasted until late Saturday.

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.

Local agencies and residents may visit for more information about flood control facilities throughout the County, as well as to view rain and stream gages, forecasts and real-time pictures.
