167-acre lake near Québec. The lake tops out around 50 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. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 167 acres wrapped in 3.5 miles of bank. With a 1.9 development index there's bank structure worth casting at, in moderation. 33% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 1.7 mi of water from one end to the other, 0.2 mi at the beam. It sits in Matawinie MRC. Lac Saint-Sébastien sits 4 mi west — 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 Break off the point first on the milk run — a drop-off near 14 ft that grades prime for summer. 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 | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (14 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

| Hiver | 3 to 20 ft | dawn | Break off the point (14 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 15 to 50 ft, and by winter most fish are in 13 to 50 ft. If you only fish one area, make it Deep basin: a deep basin around 47 ft that scores prime in summer. 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, 15 to 50 ft, and winter fish settle into 10 to 40 ft. The spot to know is Deep basin, a deep basin in about 47 ft of water that rates prime for arctic char in summer. Warm-month bites cluster around early morning. Throw a jigging spoon vertical or a tube jig (smelt) 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 Break off the point, a prime-rated drop-off around 14 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 | Main-lake point (8 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 weed flat in about 8 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.
