Stormwater Management Operating Flood Control Facilities Thursday Afternoon
Stormwater Management is currently operating Spring Creek Reservoir (Bloomingdale)
and the Armstrong Park Reservoirs (Carol Stream), as well as several smaller,
gravity-operated flood control facilities, following rainfall Thursday.
Thursday, DuPage County received up to 2 inches of rainfall countywide with the
National Weather Service forecasting an additional 0.5 inches of precipitation
through Friday. DuPage County staff anticipates stream elevations in Salt Creek
and the West Branch DuPage River will rise enough to trigger operation of some
of the County’s other large flood control facilities, including the Elmhurst
Quarry and Wood Dale-Itasca Reservoir later today and Fawell Dam (Naperville) overnight.
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 four 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.
