39-acre lake near Québec. The lake tops out around 16 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 drawn water covers 39 acres wrapped in 1.3 miles of bank. With a 1.5 development index there's bank structure worth casting at, in moderation. 92% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 0.6 mi end to end and 0.2 mi across at its widest. It sits in La Jacques-Cartier MRC. Lac de l'Éclaircie sits 3 mi northwest — the closest neighbouring chart.

Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 5 to 16 ft, then a winter hold in 2 to 16 ft. Put Deep basin first on the milk run — a deep basin near 16 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 (7 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 5 to 16 ft | dawn & dusk | Deep basin (16 ft) | 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 | 2 to 16 ft | dawn | Deep basin (16 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 5 to 16 ft before dropping to 5 to 16 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 12 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (7 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 5 to 16 ft | dusk & dawn | Break off the point (12 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 5 to 16 ft | dusk & night | Break off the point (12 ft) | Jigging rap, Jig + big minnow |
| Hiver | 5 to 16 ft | dusk & dawn | Deep basin (16 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 5 to 16 ft before dropping to 5 to 16 ft for winter. The spot to know is Back-bay flat, a weed flat in about 3 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Back-bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 5 to 16 ft | dawn | Deep basin (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
