DuPage County Stormwater Management Continues to Operate Flood Control Facilities Sunday
Sunday, October 15, 2017 – DuPage County Stormwater Management is currently operating the Elmhurst Quarry Flood Control Facility, Wood Dale-Itasca Reservoir (Wood Dale) and Spring Creek Reservoir (Bloomingdale) on Salt Creek and Fawell Dam (Naperville) and the Armstrong Park Reservoirs (Carol Stream) on the West Branch DuPage River following precipitation throughout the area beginning early Saturday through early Sunday. In addition, all of the County’s gravity-operated flood control facilities are currently in operation.
DuPage County received rainfall totals ranging from 3.5 inches to up to 7.5 inches of rainfall through early Sunday morning. This rainfall triggered operation of all of the County’s flood control facilities throughout the day Saturday.
Elevations in Salt Creek are beginning to recede near Elmhurst and should decline throughout the day. Both the West Branch and East Branch of the DuPage River are also nearing peak elevation. DuPage County Stormwater Management staff is continuing to operate the major flood control facilities and will monitor stream elevations throughout the day Sunday.
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.
