Pete,I Bay is an interesting fishery. There are catchable populations of most game fish in there, ranging from panfish to salmonoids. The walleye fishery is a target that you can have success with if you spend the time. There are enough to go around, they behave pretty much like you'd expect them to in terms of location, times, baits etc, and yes, they can get pretty darn big. There are also many other good walleye fisheries in this area, so if this is your game, you'll be able to stay busy out there.
As always, stay sharp, be safe, and best of luck to you.
