Never fished for them in that area, but what I can say is that I tend to get them where really deep water (100 foot plus) meets moderately deep water (50 or 60 feet), mainly in the main channel of the lake. Trouble is, these spots don't freeze every year, and even when they do, it's not till late in the season, and the ice is often sketchy. You'd be better off jigging from a boat if Champlain is your target.
