86-acre lake near Québec. The lake tops out around 131 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 Grasmere maps at 86 acres behind 2.6 miles of shoreline. With a 2 development index there's bank structure worth casting at, in moderation. About 9% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1.2 mi long by 0.2 mi wide at the broadest reach. Antoine-Labelle MRC claims this one. Lac Jacques sits 0 mi southeast — the closest neighbouring chart.

Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Shallow bay flat — feeding flat, 7 ft, good for spring. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (7 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (7 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 50 to 120 ft game here, winter a 20 to 80 ft one. Start at Main-lake point. It's a point holding about 23 ft of water and rates prime come spring. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.

| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (23 ft) | Casting spoon over shoals, Jerkbait (shallow) |

Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Warm water sends them out to 40 to 90 ft; cold water stacks them in 25 to 70 ft. Top water on the chart: Break off the point, a drop-off in the 74 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.

Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. Warm water sends them out to 40 to 80 ft; cold water stacks them in 20 to 60 ft. Top water on the chart: Break off the point, a drop-off in the 74 ft range, good in summer. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.

In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Main-lake point is the standout, a point at roughly 23 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

| Printemps | 4 to 15 ft | dusk & dawn | open water | 1/8 oz jig + minnow, Hair jig |

Top water on the chart: Shallow bay flat, a feeding flat in the 7 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
