12,698-acre lake near Québec. The lake tops out around 245 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. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Lac Témiscouata runs 12,698 acres with 47.5 miles of edge. An index of 3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 1% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 17.6 mi end to end and 5.1 mi across at its widest. The water lies in Témiscouata MRC. Closest neighbour on DepthScout: Grand lac Touladi, 4 mi north of here.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Offshore hump, a good-rated offshore hump around 28 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (17 ft) | Small inline spinner (gold), Tiny spoon |

| Hiver | 3 to 20 ft | dawn | Shallow bay flat (17 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts lake trout in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 50 to 120 ft, wintering in 20 to 80 ft. Winter lake trout concentrate at Offshore hump, a prime-rated offshore hump around 28 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (30 ft) | Casting spoon over shoals, Jerkbait (shallow) |

| Hiver | 20 to 80 ft | dawn | Offshore hump (28 ft) | White tube jig, Airplane jig |
Spring puts landlocked salmon in skinny water — 1 to 15 ft is the zone. Warm water sends them out to 25 to 60 ft; cold water stacks them in 10 to 40 ft. Break off the point is the standout, a drop-off at roughly 42 ft, rated prime for summer landlocked salmon. Plan around early morning and the evening in the warm months. A dodger + streamer down deep or a thin spoon on lead core covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | open water | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

| Hiver | 10 to 40 ft | dawn | Break off the point (42 ft) | Small jigging spoon, Swedish pimple + smelt |
Early season lake whitefish use the shallows, holding in 15 to 45 ft. Expect a summer slide to 40 to 90 ft, then a winter hold in 25 to 70 ft. Put Offshore hump first on the milk run — an offshore hump near 28 ft that grades prime for winter. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.

| Printemps | 15 to 45 ft | midday & dawn | Break off the point (42 ft) | Small jig + waxworm, Blade bait (small) |

Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Start at Offshore hump. It's an offshore hump holding about 28 ft of water and rates prime come summer. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.

| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (17 ft) | Small jig + curly tail, Perch-pattern micro crank |

In spring, muskellunge run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 8 to 25 ft, and winter fish settle into 15 to 35 ft. Main-lake point is the standout, a point at roughly 30 ft, rated prime for fall muskellunge. Time it for the evening and early morning. You won't need more than a double-10 bucktail or a topwater (walk-the-dog / creeper) most summer days.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | dusk | open water | Smaller bucktail (#8 blades), 6" glide bait |
| Été | 8 to 25 ft | dusk & dawn | Offshore hump (24 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
