Tours of McCook Reservoir

The MWRD plans to offer tours of the first phase of the McCook Reservoir, the last of three reservoirs to be constructed to protect area waterways from pollution and mitigate flooding, on a number of Sundays in August, September and October.

Phase One of the McCook Reservoir, part of the MWRD's Tunnel and Reservoir Plan, is set to be complete by the end of 2017, and visitors will be able to get a closer look for a limited time. Call 312.751.6632 to register for a tour.

When completed, the reservoir will have a total capacity of 10 billion gallons, beginning with the first phase to be finished this year that will provide 3.5 billion gallons of storage. Phase 2 will be completed in 2029 and provide 6.5 billion gallons of storage. The McCook Reservoir will provide an average of $143 million per year in flood damage reduction benefits to 3,100,000 people in Chicago and 36 other communities.

Tours kick off at the Mainstream Pumping Station, 6100 River Rd., in Hodgkins, IL, to view interactive displays and watch videos of TARP construction. Buses will transport visitors for a guided tour of the McCook Reservoir, located west of the Stevenson Expressway (I-55) between the Des Plaines River and Chicago Sanitary and Ship Canal.

Tours will be on Sundays: Aug. 27, Sept. 17 and 24, Oct. 1 and 15 between 9 a.m. to 2 p.m. Each tour takes approx. two hours. Please wear sturdy footwear; dresses, shorts, sandals and high heels are not permitted.
