160-acre lake near Québec. The lake tops out around 118 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. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 160 acres wrapped in 2.2 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. About 29% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.9 mi, about 0.5 mi across. It sits in Les Laurentides MRC. If the bite dies, Lac Rond is 2 mi to the east.

When the water first warms, brook trout slide up into 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. If you only fish one area, make it Break off the point: a drop-off around 13 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (13 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (13 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 35 to 118 ft, then a winter hold in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 118 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Break off the point (13 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 35 to 118 ft | dawn | Deep basin (118 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Break off the point (13 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Break off the point (13 ft) | White tube jig, Airplane jig |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Start at Break off the point. It's a drop-off holding about 13 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (6 ft) | Inline spinner (silver), Small spoon |
| Été | 8 to 30 ft | dawn & dusk | Break off the point (13 ft) | Dodger + spoon (deep troll), Flutter spoon |

| Hiver | 8 to 40 ft | dawn | Break off the point (13 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Warm water sends them out to 25 to 60 ft; cold water stacks them in 5 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 13 ft range, prime in winter. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.

Spring arctic char concentrate at Break off the point, a prime-rated drop-off around 13 ft. Warm-month bites cluster around early morning. A jigging spoon vertical or a tube jig (smelt) covers the summer program.
