Title 33 › Chapter CHAPTER 1— - NAVIGABLE WATERS GENERALLY › Subchapter SUBCHAPTER II— - WATERS DECLARED NONNAVIGABLE: CHANGE OF NAME › § 27
Declares that the stretch of the West Fork of the South Branch of the Chicago River in Cook County, Illinois — running west from the west side of the Sanitary District of Chicago’s collateral channel in the NW quarter of section 36, township 39 north, range 13 east of the Third Principal Meridian — is a nonnavigable stream under U.S. law. Congress keeps the power to change or repeal this. The Acts of September 19, 1890, and March 3, 1899, and their amendments do not apply to the west arm of the South Fork between the east side of Ashland Avenue and the north side of Thirty-ninth Street as it now exists or may later be extended. The United States gives up any control it had over that part of the Chicago River and restores full control to the State of Illinois. If, after June 7, 1924, the city of Chicago or an approved government agency or corporation builds a new channel for the South Branch between West Polk Street and West Nineteenth Street with the Secretary of the Army’s permit, the parts of the old channel that are replaced by the new channel will be discontinued and abandoned.
