| 説明 | The Cal-Sag Channel (short for "Calumet-Saganashkee Channel") is a navigation canal in southern Cook County, Illinois. It serves as a channel between the Little Calumet River and the Chicago Sanitary and Ship Canal. It is 16 miles (26 km) long and was dug over an 11-year period, from 1911 until 1922. The Cal-Sag Channel serves barge traffic in what was an active zone of heavy industry in the far southern neighborhoods of the city of Chicago, Illinois and adjacent suburbs. As of 2006 it is also used more as a conduit for wastewater from southern Cook County, including the Chicago-area Deep Tunnel Project, into the Illinois Waterway. It is also used by pleasure crafts in the summer time. The western 4.5 miles (7.3 km) of the channel flow through the Palos Hills Forest Preserves, a large area of parkland operated by Cook County Forest Preserve District. The Cal-Sag Channel served as the rowing venue for the 1959 Pan American Gamesen.wikipedia.org/wiki/Calumet_Sag_Channel#Cal-Sag_Channelen.wikipedia.org/wiki/Wikipedia:Text_of_Creative_Commons_... |
