2The Northwest Ordinance of 1787 had established the principle of the free navigation of the navigable waters leading into the Mississippi and St. Lawrence rivers and their tributaries. Early white settlers to Illinois congregated near the state’s rivers, streams, and creeks. Due in part to the lack of improved highways and in part to the belief that watercourses would remain the principle avenues for transporting people and goods, Illinoisans took pains to assure their navigability through statute. Lawmakers began enacting such laws soon after statehood, and continued the practice until 1867. Declaration as a navigable stream generally meant that no dam, mill, bridge, or other public work or obstruction could be placed on the body of water as to impede the navigation thereof, or drive the water from its natural channel so as to overflow the bottoms, or produce stagnate waters in any place.
