863-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. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 863 acres, worked by 5.1 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 26% of the surface — that's where the groceries are. End to end it runs roughly 1.8 mi, about 1.1 mi across. It sits in Le Val-Saint-François MRC. Petit lac Brompton sits 3 mi north — the closest neighbouring chart.

Spring lake trout on Lac Montjoie hold shallow, usually 10 to 40 ft. By summer they slide out to 22 to 72 ft, and by winter most fish are in 18 to 72 ft. The chart's best answer is Deep basin — deep basin, 69 ft, prime for summer. Prime time lands in early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 22 to 72 ft | dawn | Deep basin (69 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (9 ft) | Heavy casting spoon, Jigging rap over reefs |

When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 18 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.

| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver), Small spoon |

The spring pattern is a shallow one: brown trout in 3 to 25 ft. Midsummer fish sit out in 25 to 60 ft before dropping to 5 to 35 ft for winter. The spot to know is Break off the point, a drop-off in about 18 ft of water that rates prime for brown trout in winter. Plan around after dark and early morning in the warm months. Summer baits: a spoon at the thermocline or a deep stickbait (night) gets it done.

In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Summer pushes them deeper, 22 to 72 ft, and winter fish settle into 25 to 70 ft. Deep basin is the standout, a deep basin at roughly 69 ft, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
