Armstrong Park Reservoirs

Klein Creek Rendering

Completed in 2015, the Armstrong Park Reservoirs offer flood protection within the Klein Creek Watershed. The reservoirs are located along Klein Creek in Armstrong Park (Carol Stream) and have a floodwater capacity of 37 million gallons. The reservoirs were constructed as joint effort between DuPage County Stormwater Management, the Village of Carol Stream and the Carol Stream Park District to alleviate flooding for nearly 60 structures in the watershed. In order to do this, DuPage County constructed a two-reservoir system that operates when water elevations in Klein Creek increase in order to divert floodwaters from the majority of the nearby Armstrong Park neighborhood. Reservoir One takes in water directly from Klein Creek and upon reaching a specific elevation, water is pumped into Reservoir Two, a much larger storage reservoir. A 60-inch siphon under Arrowhead Trail, Indianwood Drive and Thunderbird Trail conveys water from the reservoirs back into Klein Creek once river elevations have subsided following flood events.
