After the Revolutionary War, George Washington was especially concerned with the possibility of Britain, Spain and France trying to lay claims to the rivers and thus the surrounding lands in the Western Territories. He created what became the basis for our navigable waterway laws with the Ordinance of 1787. This stated that “the navigable waters leading into the Mississippi and the St. Lawrence shall be common highways and forever free, as well to the inhabitants of said territories as to the citizens of the United States, without any impost, tax, or duty.”
