86-acre lake near Québec. The lake tops out around 12 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.
Lac Larocque maps at 86 acres behind 1.5 miles of shoreline. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.6 mi end to end and 0.3 mi across at its widest. Charlevoix MRC claims this one. Grand lac aux Montagnais sits 1 mi south — the closest neighbouring chart.

Early season brook trout use the shallows, holding in 2 to 12 ft. Even in summer they hold at 4 to 12 ft; winter keeps them in 2 to 12 ft. The chart's best answer is Deep basin — deep basin, 12 ft, prime for summer. Best bite is 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 12 ft | dawn & dusk | Shallow bay flat (2 ft) | Small inline spinner (gold), Tiny spoon |

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. The depth story barely changes: 4 to 12 ft through summer, 4 to 12 ft in winter. Top water on the chart: Back-bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
