Stormwater Management Operating Flood Control Facilities Monday

DuPage County Stormwater Management is currently operating the Elmhurst Quarry Flood Control Facility, Spring Creek Reservoir (Bloomingdale) and the Armstrong Park Reservoirs (Carol Stream), as well as all smaller, gravity-operated flood control facilities.

Beginning late Sunday, DuPage County received approximately 1.5 inches of rainfall countywide with the National Weather Service forecasting an additional 1.5 inches of precipitation through Tuesday. Combined with earlier precipitation, this rainfall elevated Salt Creek enough to trigger operation of some of the County’s large flood control facilities. In addition, the Wood Dale-Itasca Reservoir along Salt Creek and Fawell Dam (Naperville) on the West Branch DuPage River are anticipated to go into operation late Monday. 

Of the 16 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.

DuPage County Stormwater Management staff will continue to monitor stream elevations throughout the event and provide updates as they become available. Be advised that rainfall could produce localized and/or flash flooding, especially in low-lying areas.

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