Hi there. I can try to help but I don't go up there as much after the end of June. Bay fishing is still good , fish the weedlines anywhere to catch largemouth. The weedlines between misery bay and the channel are good, also between misery bay and the marina cove. I see a lot of perch fisherman around 4-5 miles east of the Presque Isle Bay channel when I'm out there smallie fishing. You'll see the pack of boats.
Smallmouth may be harder to catch in the bay now that the spawn is well over and most of them start moving out to main lake. There still may be some hanging around the humps throughout the bay but your best bet is main lake for those.
There are plenty of rock bass bites between bass bites in the bay.
