The industrial canal connects the river with the lake. From what others have posted, the river is higher than the lake.

From maps.google.com it looks like there is a canal lock between the point of the breach and the Mississippi River, so the level of the canal at the point of the breach should be at the lake level. However, the lock could presumably have been overwhelmed and the river may be flowing through the breach.
