166-acre lake near Québec. The lake tops out around 72 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.
Traced from the shoreline, Lac Pierre runs 166 acres with 2.4 miles of edge. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 37% of this chart. Call it 1 mi long by 0.4 mi wide at the broadest reach. The water lies in Matawinie MRC. For a second option, Lac Loyer lies 1 mi east.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Main-lake point, a point in about 6 ft of water that rates prime for brook trout in spring. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| 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 |

| Automne | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (11 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 22 to 72 ft, wintering in 18 to 72 ft. Top water on the chart: Deep basin, a deep basin in the 68 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Secondary point (13 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 32 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.

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

Spring brown trout on Lac Pierre hold shallow, usually 3 to 25 ft. They move out to 25 to 60 ft in summer and finish the year down in 5 to 35 ft. Put Break off the point first on the milk run — a drop-off near 32 ft that grades prime for summer. The feeding windows run after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).

| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (6 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

Come spring, look for arctic char tight to the bank in 4 to 15 ft. Expect a summer slide to 20 to 60 ft, then a winter hold in 10 to 40 ft. Start at Break off the point. It's a drop-off holding about 32 ft of water and rates prime come summer. Prime time lands in early morning. A jigging spoon vertical or a tube jig (smelt) is the honest summer answer here.
