WHEATON – DuPage County Stormwater Management expects to use its flood control facilities between 9 p.m. and midnight Wednesday, according to a county news release.
In addition to one inch of rain received on Wednesday, the National Weather Service has estimated the DuPage County area could see as many as three inches of rain through Thursday, according to the release.
This rain could cause water levels to rise in Salt Creek and the West Branch DuPage River, leading the county to operate its flood control facilities, including Fawell Dam (Naperville), Spring Creek Reservoir (Bloomingdale), Elmhurst Quarry (Elmhurst) and Wood Dale-Itasca Reservoir (Wood Dale). Other smaller facilities could operate as well.
Four of the county's 15 flood control facilities are controlled by staff based on a predetermined operating plan, according to the release. The other facilities operate without staff by using fixed weirs and natural drainage systems. The 15 facilities have a total floodwater storage capacity of nearly 4 billion gallons, the release reads.
