565-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. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 565 acres wrapped in 5.6 miles of bank. With a 1.7 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 36% of this chart. Tip to tip the water measures near 2.1 mi with a 1.2-mi widest point. It sits in Antoine-Labelle MRC. Lac Tador sits 2 mi east — the closest neighbouring chart.

Spring brook trout on Lac Rossi 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 Break off the point — drop-off, 25 ft, prime for summer. 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 | Main-lake point (7 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (25 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (6 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 22 to 72 ft, then a winter hold in 18 to 72 ft. Start at Deep basin. It's a deep basin holding about 68 ft of water and rates prime come summer. 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 | Break off the point (25 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 22 to 72 ft | dawn | Deep basin (68 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (7 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 18 to 72 ft | dawn | Deep basin (68 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: arctic char in 4 to 15 ft. As the season builds they drop to 20 to 60 ft, wintering in 10 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 25 ft range, prime in summer. Time it for early morning. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | midday & dawn | open water | Small casting spoon (silver/orange), Jerkbait (small) |
| Été | 20 to 60 ft | dawn | Break off the point (25 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Automne | 8 to 30 ft | midday & dusk | Break off the point (25 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Hiver | 10 to 40 ft | midday & dawn | Break off the point (25 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. As the season builds they drop to 22 to 72 ft, wintering in 25 to 70 ft. Top water on the chart: Deep basin, a deep basin in the 68 ft range, prime in summer. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Break off the point (25 ft) | Small jig + waxworm, Blade bait (small) |

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. Break off the point is the standout, a drop-off at roughly 25 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (7 ft) | 1/8 oz jig + minnow, Hair jig |

| Hiver | 20 to 40 ft | dusk & dawn | Break off the point (25 ft) | Jigging spoon + minnow head, Rattle bait |
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 weed flat in the 6 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.

Anglers target brook trout, lake trout, arctic char, lake whitefish, walleye, yellow perch, northern pike, smallmouth bass, rock bass, pumpkinseed, burbot on Lac Rossi. This species list is an informed estimate from Québec's provincial fish-range maps (bounded by each lake's depth and habitat), not a per-lake fish survey — Québec doesn't publish per-lake species records.
Deep basin is the top-rated area: a deep basin in about 68 ft of water that rates prime for lake trout in summer. Scroll up to the map for the complete spot list by species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
