Fasinating ,the Nigra falls power is the generater for the Flight locks ,absolutely amazing if you ever go over ,I sailed on two specific Lakers ,right up to Deluth ,I was gobsmacked to know that where we got to the trappers took their furs  many years ago ,very interesting place ,and the fresh water that is the Lakes is lovely to drink .As I said I was up there in the first convoy in 1965 ,freezing .

Why was the bow of the ship rounded and not sharp
Not sure if this is the answer? but Wiki says

Vessel speeds are not as important on the Lakes as on the ocean. Ports are often closer together than in ocean trade, so cargo capacity is more important than speed. Lake vessels are designed with the greatest box coefficient to maximize the vessel's size in the many locks within the Great Lakes/St Lawrence Seaway system. Therefore, ship designers have favored bluff bows over streamlined bows.

Here is a link to the design of the new Great Lakes fleet

 http://www.motorship.com/news101/ships-and-shipyards/new-stage-in-revitalisation-of-canadas-great-lakesseaway-fleet

There is also , I would guess, the maximisation of the lock space and ice breaking capability against a knot or so more. The bulbous bow addition is probably  less effective in the short period waves found on the Lakes.

You wouldn't want to catch the bulb on the lock sill either!!
