97-acre lake near Québec. The lake tops out around 3 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. Species by species, here's what the data says the year looks like.
The drawn water covers 97 acres wrapped in 1.8 miles of bank. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 0.8 mi of water from one end to the other, 0.3 mi at the beam. La Côte-de-Beaupré MRC claims this one. If the bite dies, Lac Davenport is 3 mi to the northeast.

Come spring, look for brook trout tight to the bank in 1 to 3 ft. Through summer count on 1 to 3 ft; the winter hold is 1 to 3 ft. If you only fish one area, make it Deep basin: a deep basin around 3 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 3 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 1 to 3 ft | dawn & dusk | Deep basin (3 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 1 to 3 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Hiver | 1 to 3 ft | dawn | Deep basin (3 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, yellow perch run shallow here, mostly 1 to 3 ft. Summer keeps them at 1 to 3 ft, and they winter in 1 to 3 ft. Shallow bay flat is the standout, a weed flat at roughly 1 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.
