213-acre lake near Québec. The lake tops out around 38 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 213 acres wrapped in 3 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 30% of this chart. The basin spans about 1.4 mi end to end and 0.3 mi across at its widest. Les Basques MRC claims this one. Lac Saint-Mathieu sits 3 mi southwest — 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 Break off the point. It's a drop-off holding about 30 ft of water and rates prime come summer. 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 (10 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Come spring, look for landlocked salmon tight to the bank in 1 to 15 ft. They move out to 11 to 38 ft in summer and finish the year down in 10 to 38 ft. If you only fish one area, make it Deep basin: a deep basin around 37 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.

Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 9 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
