27-acre lake near Québec. The lake tops out around 50 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. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 27 acres, worked by 0.9 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 35% of the surface — that's where the groceries are. Call it 0.4 mi long by 0.2 mi wide at the broadest reach. Antoine-Labelle MRC claims this one. Lac Fabre sits 0 mi southeast — the closest neighbouring chart.

Spring brook trout on Lac Cortès hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades good for spring. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| 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 |

Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 15 to 50 ft in summer and finish the year down in 13 to 50 ft. If you only fish one area, make it Deep basin: a deep basin around 49 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.

| Printemps | 10 to 40 ft | dawn & dusk | open water | Casting spoon over shoals, Jerkbait (shallow) |

Early season landlocked salmon use the shallows, holding in 1 to 15 ft. Summer is a 15 to 50 ft game here, winter a 10 to 40 ft one. The chart's best answer is Deep basin — deep basin, 49 ft, prime for summer. Best bite is early morning and the evening. Tie on a dodger + streamer down deep or a thin spoon on lead core and you're in the game.
