What are you fishing for?
How big is your boat?
How long is your stay going to be?
These will help the rest of the members give you some more specific answers.
I would recommend going anytime from Sept-end of October
The 9 mile marina is a great place to launch and Kens Marina has some of the best burgers on the lake IMO
Try fishing the mile roads from Metro to 8mile. You will be able to catch smallies, walley, pike, LM, Musky.
Drop shotting, bladebaits, tubes, cranks, and jerkbaits should be a good starting point.
