170-acre lake near Québec. The lake tops out around 70 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 170 acres of water rimmed by 3 miles of bank. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Spring brook trout concentrate at Main-lake point, a prime-rated point around 11 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 21 to 70 ft, wintering in 18 to 70 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 69 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.

Early season arctic char use the shallows, holding in 4 to 15 ft. Expect a summer slide to 20 to 60 ft, then a winter hold in 10 to 40 ft. Put Break off the point first on the milk run — a drop-off near 44 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a jigging spoon vertical or a tube jig (smelt) and you're in the game.

Come spring, look for walleye tight to the bank in 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. If you only fish one area, make it Secondary point: a point around 28 ft that scores prime in fall. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
