Mark,
Lakers are found on the bottom most of the time. Not sure about that area but I find a lot of lakers on the bottom from 90 - 200 fow. Troll slow .7 - 1.8 with cowbells and peanuts or spin-n-glows. Let it down until you hit bottom lift a foot, let it settle and repeat. Once the ball hits bottom again, keep it within 5' of the bottom. I like keeping mine 1' off the bottom. It is a lot of work but it puts fish in the boat. Depending on the area, lakers will be on large flats or structure. For example, where I fish near Sandy Creek in Hamlin, I find more lakers on structure. When I was off of I-bay, I would find lakers on deep flats.
