Belle Taine is a very fun lake to fish. My family stays up there every year for Labor Day weekend. Look to the bays and weedlines for sunnies and crappies. The bass fishing is also great in the same area. The only spot I have had luck walleye fishing is near the rocky point on the West side of the island. I have caught fish pitching jigs up towards the shoreline and trolling cranks around the edges. The 15 foot range seems to ring a bell. There is a weedline that heads North off of the point and we have caught walleyes there on slip bobbers at night. Hope some of this helps. If you just want to catch fish, through spinner baits towards the shorelines and you will catch plenty of bass and northerns.
