190-acre lake near Québec. The lake tops out around 85 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. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 190 acres, worked by 2.9 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. 42% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 1.4 mi, about 0.4 mi across. Les Laurentides MRC claims this one. If the bite dies, Lac Sainte-Marie is 2 mi to the west.

Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 26 to 85 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 85 ft that scores prime in summer. Best bite is 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 (6 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 26 to 85 ft | dawn | Deep basin (85 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (6 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Deep basin (85 ft) | White tube jig, Airplane jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. The chart's best answer is Main-lake point — point, 6 ft, prime for spring. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.

|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (6 ft) | Inline spinner (silver), Small spoon |

Spring puts brown trout in skinny water — 3 to 25 ft is the zone. As the season builds they drop to 25 to 60 ft, wintering in 5 to 35 ft. Summer brown trout concentrate at Break off the point, a prime-rated drop-off around 56 ft. Warm-month bites cluster around after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.

The spring pattern is a shallow one: arctic char in 4 to 15 ft. Midsummer fish sit out in 20 to 60 ft before dropping to 10 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 56 ft of water that rates prime for arctic char in summer. Plan around early morning in the warm months. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.

Spring walleye concentrate at Main-lake point, a prime-rated point around 6 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
