17-acre lake near Québec. The lake tops out around 40 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's the year, species by species, as the scoring engine sees it.
On the chart, Lac du Serpent draws 17 acres inside 0.6 miles of shoreline. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. About 36% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.3 mi. You'll find it in Rimouski-Neigette MRC. Closest neighbour on DepthScout: Lac du Canard, 1 mi southwest of here.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Spring brook trout concentrate at Shallow bay flat, a good-rated weed flat around 5 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (5 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 (5 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, landlocked salmon run shallow here, mostly 1 to 15 ft. Summer pushes them deeper, 12 to 40 ft, and winter fish settle into 10 to 40 ft. Deep basin is the standout, a deep basin at roughly 40 ft, rated prime for summer landlocked salmon. Time it for early morning and the evening. You won't need more than a dodger + streamer down deep or a thin spoon on lead core most summer days.

| Printemps | 1 to 15 ft | dawn & dusk | open water | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Shallow bay flat. It's a weed flat holding about 5 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |

Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 12 ft; cold water stacks them in 10 to 25 ft.
