201-acre lake near Québec. The lake tops out around 112 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 outline encloses 201 acres, worked by 2.6 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. About 27% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 1.2 mi of water from one end to the other, 0.5 mi at the beam. It sits in La Vallée-de-la-Gatineau MRC. If the bite dies, Lac Perreault is 2 mi to the southeast.

Spring brook trout on Lac Profond 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 Break off the point — drop-off, 17 ft, prime for summer. 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 | Main-lake point (7 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (17 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (17 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 34 to 112 ft, then a winter hold in 20 to 80 ft. Start at Deep basin. It's a deep basin holding about 111 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 | Break off the point (17 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 34 to 112 ft | dawn | Deep basin (111 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (7 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Break off the point (17 ft) | White tube jig, Airplane jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Put Break off the point first on the milk run — a drop-off near 17 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (7 ft) | Inline spinner (silver), Small spoon |
| Été | 8 to 30 ft | dawn & dusk | Break off the point (17 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Automne | 10 to 35 ft | dawn & dusk | Break off the point (17 ft) | Casting spoon, Jerkbait over shoals |
| Hiver | 8 to 40 ft | dawn | Break off the point (17 ft) | Jigging spoon, Tube jig (white) |
Spring puts brown trout in skinny water — 3 to 25 ft is the zone. Warm water sends them out to 25 to 60 ft; cold water stacks them in 5 to 35 ft. Break off the point is the standout, a drop-off at roughly 17 ft, rated prime for winter brown trout. Plan around after dark and early morning in the warm months. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (7 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Été | 25 to 60 ft | night & dawn | Break off the point (17 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Automne | 5 to 30 ft | dusk & dawn | Main-lake point (7 ft) | Jerkbait over gravel, Casting spoon |
| Hiver | 5 to 35 ft | dawn | Break off the point (17 ft) | Jigging spoon, Small stickbait (slow) |
The spring pattern is a shallow one: arctic char in 4 to 15 ft. As the season builds they drop to 20 to 60 ft, wintering in 10 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 17 ft range, prime in fall. Time it for early morning. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.

The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Top water on the chart: Break off the point, a drop-off in the 17 ft range, prime in spring. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
