With that much area,hydrologically it is more like an "ocean" than a series of lakes.

Yes, but our tides aren't like an ocean. I've never seen measurements on them. And they will freeze more quickly because there's no salt. They seldom freeze over completely, but when they do our winters are extremely cold and windy.

FYI, The pseudo tide in the Great Lakes is called a "sache."
You can probably find info on Google.
