330-acre lake near Québec. The lake tops out around 164 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. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 330 acres wrapped in 4.1 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. 4% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 1.9 mi, about 0.4 mi across. It sits in Les Laurentides MRC. If the bite dies, Lac Gervais is 2 mi to the southeast.

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 Back-bay flat: a feeding flat around 10 ft that scores good in spring. 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 | Back-bay flat (10 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 | Secondary point (19 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (18 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 50 to 120 ft, then a winter hold in 20 to 80 ft. Put Main-lake point first on the milk run — a point near 29 ft that grades prime for spring. 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 | Main-lake point (29 ft) | Casting spoon over shoals, Jerkbait (shallow) |

| Hiver | 20 to 80 ft | dawn | Break off the point (65 ft) | White tube jig, Airplane jig |
Come spring, look for landlocked salmon tight to the bank in 1 to 15 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 10 to 40 ft. Start at Main-lake point. It's a point holding about 29 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A dodger + streamer down deep or a thin spoon on lead core is the honest summer answer here.

| Printemps | 1 to 15 ft | dawn & dusk | Secondary point (19 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

Spring puts arctic char in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 20 to 60 ft, wintering in 10 to 40 ft. Summer arctic char concentrate at Break off the point, a prime-rated drop-off around 65 ft. Warm-month bites cluster around early morning. A jigging spoon vertical or a tube jig (smelt) covers the summer program.

Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Summer lake whitefish concentrate at Break off the point, a prime-rated drop-off around 65 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Main-lake point, a point in the 29 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
