Thanks for the responses. I did spot several creeks that seem to drain into the big lake, both north & south of the White Lake channel. Will watch out for the shipwreck/nets. When we fished out of Onekama, we would turn north & set lines at the first of the "3 Sisters", a set of 3 small dunes about 1 mile north of the channel. We would troll body baits north to "The Slide", which is a very tall dune, then turn around at Pierport and do it again, and again, etc. Some days we would run the planner boards almost on the beach. Most fish were caught on the inside board out to about 20 FOW. Back 100 feet. Guess we will try this when we get to Montague/Chaz
