Stormwater Management Operating Flood Control Facilities Monday Morning
Stormwater Management is currently operating all of its major flood control
facilities, as well as several smaller, gravity-operated flood control
facilities, following rainfall over the weekend.
Beginning Saturday afternoon, DuPage County received 2.5 to 3.5 inches of rainfall countywide with an additional ¼ of an inch forecasted through Monday. This precipitation raised
elevations in Salt Creek and the West Branch DuPage River enough to trigger
operation of the County’s large flood control facilities, including the
Elmhurst Quarry, Wood Dale-Itasca Reservoir, Fawell Dam (Naperville), Spring
Creek Reservoir (Bloomingdale) and the Armstrong Park Reservoirs (Carol Stream).
Of the 16 flood
control facilities DuPage County operates, these 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.
Stormwater Management staff will continue to monitor stream elevations and
provide updates as they become available. For more 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.
