30-acre lake near Québec. The lake tops out around 16 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 30 acres wrapped in 0.9 miles of bank. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. La Côte-de-Beaupré MRC claims this one. Lac aux Cailloux sits 1 mi south — the closest neighbouring chart.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 5 to 16 ft in summer and finish the year down in 2 to 16 ft. If you only fish one area, make it Deep basin: a deep basin around 15 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 5 to 16 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (15 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Hiver | 2 to 16 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (15 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 5 to 16 ft, wintering in 5 to 16 ft. Top water on the chart: Deep basin, a deep basin in the 15 ft range, prime in winter. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.

| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | open water | 1/8 oz jig + minnow, Hair jig |
| Été | 5 to 16 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Deep basin (15 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 5 to 16 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (15 ft) | Jigging rap, Jig + big minnow |
| Hiver | 5 to 16 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (15 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 5 to 16 ft, and winter fish settle into 5 to 16 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

Anglers target brook trout, walleye, yellow perch on Lac Magny. This species list is an informed estimate from Québec's provincial fish-range maps (bounded by each lake's depth and habitat), not a per-lake fish survey — Québec doesn't publish per-lake species records.
Deep basin is the top-rated area: a deep basin in about 15 ft of water that rates prime for walleye in winter. Scroll up to the map for the complete spot list by species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
