89-acre lake near Québec. The lake tops out around 59 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.
Lac Grégoire maps at 89 acres behind 2.1 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. About 46% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1 mi long by 0.3 mi wide at the broadest reach. It sits in Les Laurentides MRC. Lac Marie-Louise sits 1 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 Main-lake point: a point around 6 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 | Main-lake point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (7 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (7 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 18 to 59 ft, then a winter hold in 15 to 59 ft. Put Deep basin first on the milk run — a deep basin near 59 ft that grades prime for summer. 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 | Secondary point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 18 to 59 ft | dawn | Deep basin (59 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Secondary point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 15 to 59 ft | dawn | Deep basin (59 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 Break off the point. It's a drop-off holding about 7 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.

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

Come spring, look for landlocked salmon tight to the bank in 1 to 15 ft. Expect a summer slide to 18 to 59 ft, then a winter hold in 10 to 40 ft. Start at Deep basin. It's a deep basin holding about 59 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A dodger + streamer down deep or a thin spoon on lead core is the honest summer answer here.

| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (6 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

Summer arctic char concentrate at Deep basin, a prime-rated deep basin around 59 ft. Warm-month bites cluster around early morning. A jigging spoon vertical or a tube jig (smelt) covers the summer program.
