The Wood Dale/Itasca Flood Control Facility is a 1,775 acre-foot series of reservoirs located along the mainstem of Salt Creek just south of Thorndale Ave. The facility consists of 3 gravity drained reservoirs along the west side of Salt Creek totaling 325 acre-feet and 1 pump evacuated reservoir located east of Salt Creek with a 1,450 acre-foot total. The three gravity cells have been excavated and only require some site restoration work before they are complete. Some excavation of the pump evacuated cell has begun; however, approximately 2.1 million cu. yds. of earth must still be removed before it is completed along with construction of the intake facilities. The pump station used to de-water the facility during construction, and in the future to de-water the reservoir after a flood, is being constructed during the’96-’97 construction season. Excavation of the remaining earth is planned to be done by others needing earth fill and is scheduled to take until 2002. There are no current excavation contracts active.

The Westwood Creek Dam and Pump Station is located in Addison just east of Addison Rd and south of I-290. The facility is located across the Westwood Creek tributary to Salt Creek approximately 800 feet upstream of the tributary mouth. When Salt Creek rises due to a rainfall event, the flood waters, in some cases, begins traveling up the its various tributaries. In the case of Westwood Creek this "backwater" traveled far enough upstream to severely flood a residential neighborhood just west of Addison Rd. The Dam & Pump Station was constructed across Westwood Creek to prevent the flood waters from reaching the residential area.

Physically the dam has three large moveable gates which are normally left in the open position to allow normal Westwood Creek waters to flow through the dam to Salt Creek. However, when water elevation sensors on the downstream side of the dam sense that Salt Creek waters are "backing up" Westwood, the gates are automatically closed. The pumps then turn on to "lift" Westwood Creek water over the dam to prevent Westwood Creek itself from flooding the residential neighborhood. The gates then reopen when the sensors determine downstream conditions are safe.

By ordinance, the Salt Creek waters which no longer reach the low lying area along Westwood, must have a placed to be stored so that the flooding problem is not just shifted to another location. That is why this facility was built in conjunction with the Louis’ Reservoir which is explained in more detail in the Louis’ Reservoir section.
