That time of year, expect some cold, beautiful nights, some great and difficult fishing and a very good time!
The Smallmouth will more or less be done with topwater and will be moving from their summer locations to deeper, open water. The Walleye, you should still find them on humps, points and reefs and do not neglect waterfall areas if you see them. Pike, they should be everywhere!
Those cooler water temps should have them (Pike) feeding hard before the winter. Look in bays, on saddle areas between islands and the key will be any green weeds that you can still find. As weeds dye off, they use up available oxygen, green weeds still produce oxygen. If you find green weeds, water temps in the lower 60's to mid 60's, you will find Pike and perhaps some "Gators"
! Also check near waterfalls for Pike.
If you are on a lake that contains Lake Trout, those fish should start moving shallow, with the cooling waters. Lakers are fall spawners and they will start moving up on rocky points and rocky reefs in depths between 15-40 feet.
If you are throwing flies, I'd bring 7 and 8 weight rods with a floating line, and intermediate line and a type iii or iv sink tip. Streamers should be the ticket for all species!
Enjoy it. It is a special area!
