583-acre lake near Québec. The lake tops out around 180 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.
The drawn water covers 583 acres wrapped in 4.2 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. About 2% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 1.6 mi of water from one end to the other, 0.8 mi at the beam. It sits in Maskinongé MRC. Lac de la Culbute sits 1 mi south — the closest neighbouring chart.

Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Secondary point first on the milk run — a point near 14 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Secondary point (14 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |

| Hiver | 3 to 20 ft | dawn | Shallow bay flat (11 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 10 to 40 ft. By summer they slide out to 50 to 120 ft, and by winter most fish are in 20 to 80 ft. If you only fish one area, make it Main-lake point: a point around 21 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.

Start shallow in spring: arctic char sit in 4 to 15 ft that time of year. Summer pushes them deeper, 20 to 60 ft, and winter fish settle into 10 to 40 ft. The spot to know is Shallow bay flat, a feeding flat in about 11 ft of water that rates good for arctic char in spring. Warm-month bites cluster around early morning. Throw a jigging spoon vertical or a tube jig (smelt) until the fish tell you otherwise.

Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Summer pushes them deeper, 40 to 90 ft, and winter fish settle into 25 to 70 ft. The spot to know is Back-bay flat, a feeding flat in about 21 ft of water that rates prime for lake whitefish in spring. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.

In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 15 to 35 ft before dropping to 20 to 40 ft for winter. Fall walleye concentrate at Main-lake point, a prime-rated point around 21 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

| Printemps | 4 to 15 ft | dusk & dawn | Secondary point (14 ft) | 1/8 oz jig + minnow, Hair jig |

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. The spot to know is Shallow bay flat, a feeding flat in about 11 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
