Stormwater Management Operating Flood Control Facilities Early Thursday

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 the Armstrong Park Reservoirs (Carol Stream) on the West Branch DuPage River following precipitation throughout the area beginning Wednesday evening through Thursday morning. 

Portions of DuPage County received up to 1.8 inches of rainfall overnight, triggering a minor operation of four of the five mechanically operated flood control facilities, as well as the County’s 12 gravity operated facilities. The National Weather Service is not forecasting any additional rainfall through the remainder of the day. However, DuPage County Stormwater Management staff is continuing monitor stream elevations and adjust operations accordingly.

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 four 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.
