1,488-acre lake near Québec. The lake tops out around 85 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 outline encloses 1,488 acres, worked by 9.1 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. Roughly 15% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 3.1 mi, about 1.8 mi across. La Rivière-du-Nord MRC claims this one. Lac en Coeur sits 2 mi northwest — the closest neighbouring chart.

Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 26 to 85 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 80 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Secondary point (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 26 to 85 ft | dawn | Deep basin (80 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Secondary point (19 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Deep basin (80 ft) | White tube jig, Airplane jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. The chart's best answer is Break off the point — drop-off, 13 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Été | 8 to 30 ft | dawn & dusk | Break off the point (13 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Automne | 10 to 35 ft | dawn & dusk | Secondary point (19 ft) | Casting spoon, Jerkbait over shoals |
| Hiver | 8 to 40 ft | dawn | Break off the point (13 ft) | Jigging spoon, Tube jig (white) |
Spring puts brown trout in skinny water — 3 to 25 ft is the zone. As the season builds they drop to 25 to 60 ft, wintering in 5 to 35 ft. Winter brown trout concentrate at Break off the point, a prime-rated drop-off around 13 ft. Warm-month bites cluster around after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

| Hiver | 5 to 35 ft | dawn | Break off the point (13 ft) | Jigging spoon, Small stickbait (slow) |
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. Midsummer fish sit out in 26 to 85 ft before dropping to 25 to 70 ft for winter. The spot to know is Deep basin, a deep basin in about 80 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Break off the point (13 ft) | Small jig + waxworm, Blade bait (small) |

Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 13 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |

Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Break off the point, a drop-off in about 13 ft of water that rates prime for yellow perch in summer. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
