2,373-acre lake near Québec. The lake tops out around 80 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 2,373 acres wrapped in 24.5 miles of bank. An index of 3.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 45% of this chart. The basin spans about 11 mi end to end and 1.5 mi across at its widest. It sits in Témiscouata MRC. If the bite dies, Le Beau Lac is 9 mi to the southwest.

When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 25 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (25 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (9 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (4 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 24 to 80 ft, then a winter hold in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 79 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Secondary point (13 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Come spring, look for landlocked salmon tight to the bank in 1 to 15 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 10 to 40 ft. Start at Break off the point. It's a drop-off holding about 25 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A dodger + streamer down deep or a thin spoon on lead core is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Été | 25 to 60 ft | dawn & dusk | Break off the point (25 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Automne | 5 to 30 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon at the mouths, Streamers |
| Hiver | 10 to 40 ft | dawn | Break off the point (25 ft) | Small jigging spoon, Swedish pimple + smelt |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 24 to 80 ft, wintering in 25 to 70 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 79 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.

| Printemps | 15 to 45 ft | midday & dawn | Break off the point (25 ft) | Small jig + waxworm, Blade bait (small) |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

The summer box starts with a double-10 bucktail or a topwater (walk-the-dog / creeper).

|---|---|---|---|---|
| Printemps | 3 to 12 ft | dusk | Shallow bay flat (4 ft) | Smaller bucktail (#8 blades), 6" glide bait |
