§27 Chicago River at Chicago, Illinois

Summary

A specific stretch of the West Fork of the South Branch of the Chicago River in Cook County, Illinois — the part running west from the west line of the sanitary district’s collateral channel in the northwest quarter of section 36, township 39 north, range 13 east of the third principal meridian — is declared nonnavigable under the Constitution and laws of the United States. Congress keeps the right to change or repeal that decision. The Acts of September 19, 1890, and March 3, 1899 (and any changes to them) do not apply to the west arm of the South Fork of the South Branch that lies between the east line of Ashland Avenue and the north line of Thirty-ninth Street in Chicago, as it now exists or may be extended. The United States gives up any control or rights over that part of the river, and those powers go back to the State of Illinois. If, after June 7, 1924, the city of Chicago or another government agency or a corporation authorized by the Secretary of the Army builds a new South Branch channel between West Polk Street and West Nineteenth Street with the Secretary’s permit, the old channel replaced by that new work will be discontinued and abandoned.
