DuPage County Stormwater Management Operating Flood Control Facilities Saturday

DuPage County Stormwater Management is currently operating the Elmhurst Quarry Flood Control and Spring Creek Reservoir (Bloomingdale) on Salt Creek following precipitation throughout the area beginning early Saturday. 

DuPage County received rainfall totals ranging from 2.5 inches to up to 5 inches throughout the day Saturday. The National Weather Service is forecasting an additional 1.5 to 2.5 inches of rainfall through early Sunday. The rainfall triggered operation of the Elmhurst Quarry and Spring Creek Reservoir, as well as several of the County’s smaller gravity-operated facilities. Flood forecasts indicate the remaining larger facilities, including the Wood Dale-Itasca Reservoir, Armstrong Park Reservoirs (Carol Stream) and Fawell Dam (Naperville), will go into operation later Saturday.

DuPage County Stormwater Management staff will continue to monitor stream elevations throughout the event and provide updates as they become available. Be advised that this precipitation may also cause localized and flash flooding, especially in low-lying areas.

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 four billion gallons.
