948-acre lake near Québec. The lake tops out around 220 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. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 948 acres wrapped in 5.5 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. About 2% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 1.7 mi end to end and 1.4 mi across at its widest. It sits in Mékinac MRC. Lac du Camp sits 1 mi west — the closest neighbouring chart.

Spring brook trout on Lac Sassamaskin hold shallow, usually 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. The chart's best answer is Shallow bay flat — feeding flat, 13 ft, good for spring. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (13 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 (13 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Start at Main-lake point. It's a point holding about 30 ft of water and rates prime come spring. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (30 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Break off the point (120 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (30 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Deep basin (220 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Top water on the chart: Back-bay flat, a feeding flat in the 14 ft range, prime in spring. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.

| Printemps | 15 to 45 ft | midday & dawn | Back-bay flat (14 ft) | Small jig + waxworm, Blade bait (small) |

| Hiver | 25 to 70 ft | midday & dawn | Deep basin (220 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: cisco (lake herring) in 10 to 40 ft. As the season builds they drop to 40 to 80 ft, wintering in 20 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 220 ft range, good in spring. Time it for early morning. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.

Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Main-lake point is the standout, a point at roughly 30 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.

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

Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Shallow bay flat, a feeding flat in the 13 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
