Lake Trout fishing at Irish Lake
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Summer pushes them deeper, 19 to 62 ft, and winter fish settle into 16 to 62 ft. The spot to know is Deep basin, a deep basin in about 53 ft of water that rates prime for lake trout in summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
