Stormwater Management Operating Flood Control Facilities Thursday
County Stormwater Management is continuing operation of all its flood control
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
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.
