29-acre lake near Québec. The lake tops out around 60 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 follows comes from the same scoring engine that paints the spots above.
Lac Langevin maps at 29 acres behind 0.8 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 12% of the surface — that's where the groceries are. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. Antoine-Labelle MRC claims this one. Lac Michaud sits 1 mi southeast — the closest neighbouring chart.

Spring brook trout on Lac Langevin 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 feeding flat near 14 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 (14 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 | open water | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (14 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 18 to 60 ft in summer and finish the year down in 15 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 60 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | open water | Casting spoon over shoals, Jerkbait (shallow) |

| Automne | 10 to 50 ft | dusk & dawn | open water | Heavy casting spoon, Jigging rap over reefs |

Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. The chart's best answer is Shallow bay flat — feeding flat, 14 ft, good for spring. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.

The spring pattern is a shallow one: arctic char in 4 to 15 ft. Midsummer fish sit out in 20 to 60 ft before dropping to 10 to 40 ft for winter. The spot to know is Deep basin, a deep basin in about 60 ft of water that rates prime for arctic char in summer. Plan around early morning in the warm months. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.

Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Summer walleye concentrate at Back-bay flat, a good-rated feeding flat around 21 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
