Wolf Lake is an lake that straddles the Indiana and Illinois state line near Lake Michigan.〔(New Vision for Wolf Lake - News of the Wild - Summer 2001 )〕 It is smaller than it was prior to settlement by people of European descent because of infilling for development around the edges. Despite years of environmental damage caused by heavy industries, transportation infrastructure, urban runoff and filling of wetlands, it is one of the most important biological sites in the Chicago region. Wolf Lake was once connected by an open channel to Lake Michigan on the Indiana side of the lake, but this channel was cut off for development on its northern side. Indianapolis Boulevard (U.S. 41) and various railroad and industrial facilities are located in former wetlands on the northeastern side of the lake where it once connected to Lake Michigan. There are currently proposals to reopen a channel between Wolf Lake and Lake Michigan. The Illinois portion of the lake consists of five, interconnected impoundments separated by dikes. The dikes were constructed in the late 1950s so that separate portions of the lake could be drained for the purpose of dredging for fill to use in the construction of the Chicago Skyway. The western impoundments are now part of the William W. Powers State Recreation Area and are drained by Indian Creek to the Calumet River. The Wolf Lake water level determines the drainage to Lake Michigan because the connecting Calumet River flows southward during elevated levels and northward during lowered levels. The Indiana portion of the lake consists of three, interconnected impoundments that are also separated by dikes. The longest dike, running roughly parallel to State Line Road and traversing the entire length of the lake, contains railroad tracks belonging to the Indiana Harbor Belt. The Indiana Toll Road (Interstate 90) runs through the middle of the lake just inside the Indiana state line. The lake is also transected by a number of railroad causeways, some of them no longer in use. Indiana Harbor Belt Railroad has an active spur line that runs through the Illinois side of the lake in the Hegewisch community area. Calumet Avenue (U.S. 41) is on its eastern side, with a strip of parkland in between. There are currently several large industrial properties adjacent to the lake and on filled wetlands adjoining the lake, including Cargill and Unilever on the north side. Other property near the edge of the lake is being used for housing. A significant portion of the property around the lake is now parkland or nature preserve, including the Eggers Woods parcel of the Forest Preserve District of Cook County. Other neighboring lakes include Lake George, Lake Calumet, Powderhorn Lake and Lake Michigan. There was also another lake that laid to the west between Wolf Lake and the river. It was called Hyde Lake and was filled in by Republic Steel. The swampy area near 130th Street and the railroad tracks is the only remaining portion of the lake. ==History== Wolf Lake in Illinois has a storied history that somehow has lost track of the origins of the name that goes back over 150 years. Part of this history includes visits by Abraham Lincoln in which Mary Todd Lincoln nearly drowned. In 1924, the body of Bobby Franks was found in a culvert just northwest of the lake. Franks was the victim of the so-called "thrill killers," Leopold and Loeb – the subjects of what was termed the "Trial of the Century." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wolf Lake (Indiana–Illinois)」の詳細全文を読む スポンサード リンク
