Its never going to happen. The city of Waukesha Wisconsin is less than 20 miles from lake Michigan and they can't draw water from Lake Michigan for their municipal water supply.
Apparently they're just outside the great lakes watershed and apparently taking water from the watershed while runoff goes into the Mississippi watershed is a no no. (They are working on a means of putting the wastewater back into the Lk Michigan watershed)
