5,373-acre lake near Québec. The lake tops out around 330 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. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Lac Memphrémagog runs 5,373 acres with 27.2 miles of edge. An index of 2.7 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 1% of this chart. Call it 9.5 mi long by 3.1 mi wide at the broadest reach. For a second option, Lake Memphremagog lies 3 mi southeast.

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 50 to 120 ft; cold water stacks them in 20 to 80 ft. Offshore hump is the standout, an offshore hump at roughly 40 ft, rated prime for winter lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Offshore hump (40 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Offshore hump (40 ft) | Heavy casting spoon, Jigging rap over reefs |

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Winter rainbow trout concentrate at Sharp break, a prime-rated drop-off around 15 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (19 ft) | Inline spinner (silver), Small spoon |

Come spring, look for brown trout tight to the bank in 3 to 25 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 5 to 35 ft. Start at Sharp break. It's a drop-off holding about 15 ft of water and rates prime come winter. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.

|---|---|---|---|---|
| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (19 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

Early season lake whitefish use the shallows, holding in 15 to 45 ft. Summer is a 40 to 90 ft game here, winter a 25 to 70 ft one. The chart's best answer is Offshore hump — offshore hump, 40 ft, prime for summer. Best bite is early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.

The chart's best answer is Offshore hump — offshore hump, 40 ft, prime for winter. Best bite is early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.

It's an offshore hump holding about 20 ft of water and rates prime come summer. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
