The old Calumet River channel in sections 18 and 19, township 37 north, range 15 east, third principal meridian, Cook County, Illinois, that lies outside the new channel lines shown on the map in section 26 and outside the turning basin limits in those sections will no longer be a navigable water of the United States. That change takes effect when the United States acquires the land needed to build the turning basin at a site between 113th Street and 117th Street in Chicago, as approved by the Chief of Engineers.
