Spring brook trout on Les Quatre Lacs hold shallow, usually 2 to 15 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Deep basin — deep basin, 25 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.

Deep basin is the standout, a deep basin at roughly 25 ft, rated prime for winter walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
