Interesting thing with that tool, it doesn't show any rise in the great lakes, I wonder if they would rise at all.

They are higher than the ocean (Niagara Falls!) so no - unless the paths between them and the path to the ocean gets blocked they won't rise.

All else being the same I would expect the great lakes to rise. My guess is that the lake levels are so strongly tied to rainfall patterns that it's pointless to predict their future levels right now.
