DuPage County Stormwater Management Begins Operation of Flood Control Facilities

DuPage County Stormwater Management is operating two of its larger flood control facilities – Fawell Dam (Naperville) and Spring Creek Reservoir (Bloomingdale) – early Wednesday morning because of overnight precipitation.

The National Weather Service forecasted two inches of rain throughout the area late Tuesday into early Wednesday. While actual rainfall totaled 1.5 inches or less, this precipitation raised elevations in Salt Creek and the West Branch DuPage River enough for Stormwater Management to operate the two flood control facilities. However, operation of all facilities was not necessary in this event.

Of the 15 flood control facilities DuPage County operates, five larger facilities – including Fawell Dam and Spring Creek Reservoir – 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.

While river elevations may continue to rise throughout the day, the County does not anticipate operation of any other flood control facilities. Additionally, the County expects operation of Fawell Dam and Spring Creek Reservoir to be relatively short.
