Stormwater Management Operating Flood Control Facilities Wednesday
Stormwater Management is currently operating all of its flood control
facilities early Wednesday.
week, DuPage County received approximately 3.5 to 4.5 inches of rainfall countywide
with the National Weather Service forecasting an additional ¼ 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.
Stormwater Management staff will continue to monitor stream elevations
throughout the event and provide updates as they become available. Be advised
that rainfall could produce localized and/or flash flooding, especially in
information, local agencies and residents may visit http://ec.dupageco.org/dec/stormwater/watershed/index.html
to learn about flood control facilities throughout the County, as well as to
view rain and stream gages, forecasts and real-time pictures.
