367-acre lake near Québec. The lake tops out around 263 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. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 367 acres wrapped in 3.5 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 4% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 1.4 mi, about 0.7 mi across. Maskinongé MRC claims this one. If the bite dies, Lac en Croix is 3 mi to the northeast.

Spring brook trout on Lac Larose hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Back-bay flat first on the milk run — a feeding flat near 9 ft that grades good for spring. The feeding windows run 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 | Back-bay flat (9 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 (16 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Main-lake point: a point around 35 ft that scores prime in spring. Best bite is 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 (35 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Deep basin (260 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (35 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Deep basin (260 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: arctic char in 4 to 15 ft. Midsummer fish sit out in 20 to 60 ft before dropping to 10 to 40 ft for winter. The spot to know is Back-bay flat, a feeding flat in about 9 ft of water that rates good for arctic char in spring. Plan around early morning in the warm months. 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 | Back-bay flat (9 ft) | Small casting spoon (silver/orange), Jerkbait (small) |

| Hiver | 10 to 40 ft | midday & dawn | Deep basin (260 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. Midsummer fish sit out in 40 to 90 ft before dropping to 25 to 70 ft for winter. The spot to know is Shallow bay flat, a feeding flat in about 16 ft of water that rates prime for lake whitefish in spring. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.

Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Fall walleye concentrate at Main-lake point, a prime-rated point around 35 ft. Warm-month bites cluster around the evening and early morning. 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. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Back-bay flat, a feeding flat in about 9 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. 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, brown bullhead, burbot on Lac Larose. 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.
Main-lake point is the top-rated area: a point in about 35 ft of water that rates prime for walleye in fall. The interactive chart above rates every spot for each 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.
