Weed lines, rock piles 6 FOW+, or troll right down the middle. You’ll run into everything by trolling cranks or spinners, don’t be afraid to go fast (3mph+). Remember you can have two lines per angler on Big Stone, helps with the trolling spread or when bobber fishing.
Good amount of eater walleyes in the lake right now. Perch have been easier to find up the lake from the Meadowbrook area the last couple summers and there’s a fair amount of eater crappies out there now, too. LMB is really underrated if you’re into that, in certain spots by the islands there’s plenty of 3lb fish to be had.
Might be a bit early for the deep rock bite to start but it won’t hurt to try. Bring all kinds of bait if you fish deep rocks, fish tend to have a preference day to day. Night bite can be good off shore if weeds allow, lighted bobbers are always fun.
Hope this helps, good luck
