100-acre lake near Québec. The lake tops out around 85 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. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 100 acres of water rimmed by 1.8 miles of bank, broken up by an island. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. 25% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.7 mi end to end and 0.3 mi across at its widest. The water lies in Maskinongé MRC. For a second option, Lac de la Culbute lies 1 mi northwest.

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. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 29 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.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 26 to 85 ft, wintering in 20 to 80 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 85 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Break off the point (29 ft) | Casting spoon over shoals, Jerkbait (shallow) |

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 29 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.

| Printemps | 4 to 15 ft | midday & dawn | open water | Small casting spoon (silver/orange), Jerkbait (small) |

Early season lake whitefish use the shallows, holding in 15 to 45 ft. Expect a summer slide to 26 to 85 ft, then a winter hold in 25 to 70 ft. Put Deep basin first on the milk run — a deep basin near 85 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon 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 Break off the point: a drop-off around 29 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.

| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |

Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Start at Break off the point. It's a drop-off holding about 29 ft of water and rates prime come summer. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
