By 1848, with the opening of the Illinois and Michigan Canal at Chicago, direct access to the Mississippi River was possible from the lakes.

Kierans disputed the accuracy of the 1959 Canadian government's position and asserted that the GRAND Canal could provide additional fresh water to the Great Lakes.
