168-acre lake near Québec. The lake tops out around 180 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. Species by species, here's what the data says the year looks like.
On the chart, Lac Boisseau draws 168 acres inside 2.6 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 5% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 1.2 mi end to end and 0.3 mi across at its widest. The water lies in Les Laurentides MRC. Closest neighbour on DepthScout: Lac des Trois Montagnes, 3 mi southeast of here.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Main-lake point, a point in the 15 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (15 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 | Main-lake point (15 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (14 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Summer pushes them deeper, 50 to 120 ft, and winter fish settle into 20 to 80 ft. The spot to know is Main-lake point, a point in about 15 ft of water that rates prime for lake trout in spring. Warm-month bites cluster around early morning. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Break off the point (106 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (15 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Deep basin (180 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. The spot to know is Main-lake point, a point in about 15 ft of water that rates prime for rainbow trout in spring. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.

|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (15 ft) | Inline spinner (silver), Small spoon |

| Hiver | 8 to 40 ft | dawn | Break off the point (106 ft) | Jigging spoon, Tube jig (white) |
Early season brown trout use the shallows, holding in 3 to 25 ft. Summer is a 25 to 60 ft game here, winter a 5 to 35 ft one. The chart's best answer is Main-lake point — point, 15 ft, prime for spring. Best bite is after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.

| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (15 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

When the water first warms, arctic char slide up into 4 to 15 ft. By summer they slide out to 20 to 60 ft, and by winter most fish are in 10 to 40 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 14 ft that scores good in spring. In summer the feeding windows fall in early morning. Keep a jigging spoon vertical or a tube jig (smelt) rigged through the warm months.

When the water first warms, lake whitefish slide up into 15 to 45 ft. By summer they slide out to 40 to 90 ft, and by winter most fish are in 25 to 70 ft. If you only fish one area, make it Back-bay flat: a feeding flat around 18 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
