687-acre lake near Québec. The lake tops out around 53 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. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 687 acres wrapped in 7.8 miles of bank. With a 2.1 development index there's bank structure worth casting at, in moderation. About 34% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 3.7 mi with a 0.5-mi widest point. It sits in L'Islet MRC. Its nearest charted neighbour, Lac Bringé, is 1 mi to the southeast.

Spring brook trout on Lac Trois Saumons hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Secondary point — point, 4 ft, prime for spring. Prime time lands in 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 | Secondary point (4 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (6 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Secondary point (4 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 16 to 53 ft, then a winter hold in 13 to 53 ft. Start at Deep basin. It's a deep basin holding about 51 ft of water and rates prime come summer. Prime time lands in 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 | Main-lake point (18 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 16 to 53 ft | dawn | Deep basin (51 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (18 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 13 to 53 ft | dawn | Deep basin (51 ft) | White tube jig, Airplane jig |
Early season landlocked salmon use the shallows, holding in 1 to 15 ft. Expect a summer slide to 16 to 53 ft, then a winter hold in 10 to 40 ft. Put Deep basin first on the milk run — a deep basin near 51 ft that grades prime for summer. In summer the feeding windows fall in 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Secondary point (4 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

| Hiver | 10 to 40 ft | dawn | Main-lake point (18 ft) | Small jigging spoon, Swedish pimple + smelt |

Top water on the chart: Deep basin, a deep basin in the 51 ft range, prime in summer. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.

Top water on the chart: Deep basin, a deep basin in the 51 ft range, prime in summer. Time it for early morning. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.

Top water on the chart: Shallow bay flat, a weed flat in the 4 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
