252-acre lake near Québec. The lake tops out around 102 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. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 252 acres wrapped in 4.5 miles of bank. A middling shoreline index (2) gives it some bays to work without being a maze. 3% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 1.9 mi long by 0.5 mi wide at the broadest reach. Maskinongé MRC claims this one. Its nearest charted neighbour, Lac du Gros Ours, is 1 mi to the north.

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 Feeding flat. It's a feeding flat holding about 23 ft of water and rates good come winter. 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 | open water | 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 | open water | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Feeding flat (23 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 31 to 102 ft game here, winter a 20 to 80 ft one. The chart's best answer is Deep basin — deep basin, 97 ft, prime for summer. 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 | Main-lake point (28 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 31 to 102 ft | dawn | Deep basin (97 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (28 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Break off the point (59 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 Break off the point: a drop-off around 59 ft that scores prime in summer. 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 | Secondary point (20 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

| Hiver | 10 to 40 ft | dawn | Main-lake point (28 ft) | Small jigging spoon, Swedish pimple + smelt |
Spring puts arctic char in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 20 to 60 ft; cold water stacks them in 10 to 40 ft. Break off the point is the standout, a drop-off at roughly 59 ft, rated prime for summer arctic char. Plan around early morning in the warm months. A jigging spoon vertical or a tube jig (smelt) covers the summer program.

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

Deep basin is the standout, a deep basin at roughly 97 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.

Break off the point is the standout, a drop-off at roughly 59 ft, rated prime for winter cisco (lake herring). Plan around early morning in the warm months. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.
