272-acre lake near Québec. The lake tops out around 131 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:
The outline encloses 273 acres, worked by 3.5 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. 31% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 1.4 mi long by 0.7 mi wide at the broadest reach. Charlevoix MRC claims this one. If the bite dies, Lac au Porc-Épic is 3 mi to the west.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Secondary point: a point around 9 ft that scores prime in spring. 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 | Secondary point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Secondary point (9 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (8 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring lake trout on Lac Malfait hold shallow, usually 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. Put Main-lake point first on the milk run — a point near 16 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
