6,524-acre lake near Lac-Mégantic. The lake tops out around 248 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.
Lac Mégantic maps at 6,836 acres behind 34.4 miles of shoreline. That shoreline is heavily fingered (development index 3) — bays, points and pockets everywhere, which multiplies the fishable edge. About 17% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 10.2 mi with a 3.1-mi widest point. It sits in Le Granit MRC. Lac des Trois Milles sits 12 mi north — the closest neighbouring chart.

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 Creek inflow: an inflow / creek mouth around 8 ft that scores prime 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 | Creek inflow (8 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Creek inflow (8 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Creek inflow (8 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Creek inflow (8 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 Rock reef first on the milk run — a rock pile near 9 ft that grades prime for fall. 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 | Rock reef (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Sharp break (62 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Rock reef (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Sharp break (62 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 Creek inflow. It's an inflow / creek mouth holding about 8 ft of water and rates prime come spring. 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 | Creek inflow (8 ft) | Inline spinner (silver), Small spoon |
| Été | 8 to 30 ft | dawn & dusk | Creek inflow (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Automne | 10 to 35 ft | dawn & dusk | Rock reef (9 ft) | Casting spoon, Jerkbait over shoals |
| Hiver | 8 to 40 ft | dawn | Old creek channel (12 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: Creek inflow, an inflow / creek mouth in the 8 ft range, prime in spring. 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.

| Printemps | 3 to 25 ft | dawn & dusk | Creek inflow (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

| Hiver | 5 to 35 ft | dawn | Creek inflow (8 ft) | Jigging spoon, Small stickbait (slow) |
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. Fall lake whitefish concentrate at Rock reef, a prime-rated rock pile around 9 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |

| Printemps | 15 to 45 ft | midday & dawn | Shallow bay flat (15 ft) | Small jig + waxworm, Blade bait (small) |

Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 40 to 80 ft, wintering in 20 to 60 ft. Fall cisco (lake herring) concentrate at Rock reef, a prime-rated rock pile around 9 ft. Warm-month bites cluster around early morning. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.

Anglers target brook trout, lake trout, rainbow trout, brown trout, lake whitefish, cisco (lake herring), walleye, yellow perch, northern pike, smallmouth bass, pumpkinseed, brown bullhead, burbot, chain pickerel on Lac Mégantic. This species list is an informed estimate from Québec's provincial fish-range maps (bounded by each lake's depth and habitat), not a per-lake fish survey — Québec doesn't publish per-lake species records.
Creek inflow is the top-rated area: an inflow / creek mouth in about 8 ft of water that rates prime for brook trout in spring. Scroll up to the map for the complete spot list by species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
