Well, my father in law (FIL, for easier typing) is taking my wife and I fishing for lake trout for our aniversary

I've never been for lake trout before, and I'm unfamiliar with the lake also - Lucky lake, off Brule lake. The lake doesn't even show up on the map, it's between the lake and the schooner road. It does show up if you look at the satelite or hybrid view.
Apparently, the west shore is shallow and slopes down slowly, and the north-east shore is cliffs, and deep.
I'd guess the lakers would be off the cliff-shore, down around 50-60 feet?
I don't have a downrigger, so it's all gonna be by guess and by golly.
Any hints, or local knowledge about the lake? I'll try and post pictures from the trip when we get back (we're gonna be there for the 7-8-9-10 of September).
