Saganashkee Slough is a 377 acres (153 ha), manmade riparian lake that forms part of the valley of the Cal-Sag Channel. It is located in the Palos Forest Preserves of Cook County, Illinois, on wetland that was drained but was later reverted to a lake starting in 1948-1949 by the construction of dams and levees. Saganashkee Slough, like other segments of the Cal-Sag canal and valley system, drains into the Des Plaines River and ultimately into the Illinois River.
