There are two ways to pursue these fish. The first method is long line trolling with lead core line. The second is vertical jigging. Use a graph in deep bays to locate fish. You will need a 7 to 7.5 foot medium-action rod with a level wind reel, and 100 yards of lead core with 7 to 10 foot mono leader.
Lure selection is relatively easy, use spoons.
A lot of the fun in long line trolling is watching the graph. Try to imagine how big that fish could be as your spoon flutters 100 yards behind you. Lake Trout hang out and feed in large schools. There are usually a couple of trophy fish among each school. Get out and try laker fishing, lead core trolling makes it easy.
