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.

This is a series, on every Tuesday for a few weeks. Easy to miss so I've put it on Series Record.

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