168-acre lake near Québec. The lake tops out around 60 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. Species by species, here's what the data says the year looks like.
Drawn out, this is 168 acres of water rimmed by 2.5 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. About 55% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1 mi with a 0.5-mi widest point. The water lies in La Vallée-de-la-Gatineau MRC. Closest neighbour on DepthScout: Lac Malpighie, 2 mi northeast of here.

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 Break off the point, a drop-off in about 16 ft of water that rates prime for brook trout in summer. 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 (10 ft) | Small inline spinner (gold), Tiny spoon |

| Automne | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (16 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 18 to 60 ft, wintering in 15 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 60 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 | Main-lake point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. Expect a summer slide to 18 to 60 ft, then a winter hold in 18 to 60 ft. Start at Deep basin. It's a deep basin holding about 60 ft of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.

Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. Expect a summer slide to 18 to 60 ft, then a winter hold in 20 to 60 ft. Start at Deep basin. It's a deep basin holding about 60 ft of water and rates prime come summer. Prime time lands in early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.

Spring walleye on Lac Greffard hold shallow, usually 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. Put Break off the point first on the milk run — a drop-off near 16 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).

| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (10 ft) | 1/8 oz jig + minnow, Hair jig |

Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft.

Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
