Flood Control Operations

Flood Control Operations

The County is responsible for operating flood control facilities during extreme rain events and ensuring adequate maintenance is performed on these facilities. This program provides regional flood protection through the operation of rain and stream gage networks, flood forecast computer modeling, and operation of the flood control structures.

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.
