Stormwater Management Operating Flood Control Facilities Thursday

DuPage County Stormwater Management is continuing operation of all its flood control facilities Thursday.

Throughout the week, DuPage County received approximately 4.5 to 5.5 inches of rainfall countywide with the National Weather Service forecasting an additional 0.5 inches through Thursday. This rainfall elevated streams enough countywide to trigger operation of both larger, mechanically operated flood control facilities and smaller, gravity operated flood control facilities. 

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 additional 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 gauges, forecasts and real-time pictures.
