1,409-acre lake near Québec. The lake tops out around 149 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. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 1,409 acres wrapped in 10.6 miles of bank. A middling shoreline index (2) gives it some bays to work without being a maze. Roughly 10% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 3.5 mi, about 1.5 mi across. Manicouagan MRC claims this one. Lac Fer à Cheval sits 2 mi west — the closest neighbouring chart.

When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Main-lake point. It's a point holding about 7 ft of water and rates prime come spring. The feeding windows run 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 (7 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 |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (18 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 50 to 120 ft game here, winter a 20 to 80 ft one. The chart's best answer is Secondary point — point, 13 ft, prime for spring. Best bite is 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) |
| Été | 50 to 120 ft | dawn | Break off the point (88 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Secondary point (13 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Break off the point (88 ft) | White tube jig, Airplane jig |
Come spring, look for landlocked salmon tight to the bank in 1 to 15 ft. They move out to 25 to 60 ft in summer and finish the year down in 10 to 40 ft. If you only fish one area, make it Main-lake point: a point around 7 ft that scores prime in spring. Best bite is 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 (7 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Été | 25 to 60 ft | dawn & dusk | Deep basin (140 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Automne | 5 to 30 ft | dawn & dusk | Main-lake point (7 ft) | Casting spoon at the mouths, Streamers |
| Hiver | 10 to 40 ft | dawn | Secondary point (13 ft) | Small jigging spoon, Swedish pimple + smelt |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. Warm water sends them out to 40 to 90 ft; cold water stacks them in 25 to 70 ft. Break off the point is the standout, a drop-off at roughly 88 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.

|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Shallow bay flat (18 ft) | Small jig + waxworm, Blade bait (small) |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Spring yellow perch concentrate at Back-bay flat, a prime-rated feeding flat around 13 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Back-bay flat (13 ft) | Small jig + curly tail, Perch-pattern micro crank |

The summer box starts with a bucktail or a weedless spoon over cabbage.
