DuPage County Stormwater Management Operates Flood Control Facilities Friday Morning

DuPage County Stormwater Management is operating the Elmhurst Quarry Flood Control Facility (Elmhurst), Spring Creek Reservoir (Bloomingdale) and Fawell Dam (Naperville) as of early Friday morning due to heavy overnight precipitation.

DuPage County received 1.5 to 4 inches of rain countywide Thursday afternoon into early Friday morning. This precipitation increased stream elevations enough Friday morning to warrant operation of the Elmhurst Quarry and Spring Brook Reservoir along Salt Creek and the Fawell Dam along the West Branch DuPage River. Several smaller, gravity operated facilities are also operating.

While minimal rainfall is forecasted through the remainder of Friday morning, Stormwater Management staff will continue to monitor river elevations in both Salt Creek and the West Branch DuPage River and operate the flood control facilities as necessary. In addition, low-lying areas may experience localized flooding and a flash flood warning from the National Weather Service remains in effect.

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.

Residents may visit ec.dupageco.org/dec/stormwater/watershed/index.html for more information about flood control facilities throughout the County, as well as to view rain and stream gages, forecasts and real-time pictures.
