165-acre lake near Québec. The lake tops out around 23 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. What the data behind the map says about each species, season by season:
Lac des Castors maps at 165 acres behind 2.9 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 88% of this chart. Call it 1 mi long by 0.6 mi wide at the broadest reach. Charlevoix MRC claims this one. If the bite dies, Lac Sicard is 1 mi to the south.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 7 to 23 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 22 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 | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 7 to 23 ft | dawn & dusk | Deep basin (22 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (3 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 7 to 23 ft, and winter fish settle into 7 to 23 ft. Deep basin is the standout, a deep basin at roughly 22 ft, rated prime for fall 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.
