3,682-acre lake near Notre-Dame-de-la-Merci. The lake tops out around 182 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.
Lac Ouareau maps at 3,421 acres behind 26.5 miles of shoreline, with 2 islands in the mix. That shoreline is heavily fingered (development index 3.2) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 23% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 7 mi with a 3.1-mi widest point. Matawinie MRC claims this one. Lac Beauchamp sits 2 mi west — the closest neighbouring chart.

When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Rivière Ouareau inflow. It's an inflow / creek mouth holding about 7 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Rivière Ouareau inflow (7 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Rivière Ouareau inflow (7 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Rivière Ouareau inflow (7 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Rivière Ouareau inflow (7 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 50 to 120 ft game here, winter a 20 to 80 ft one. The chart's best answer is Rock reef — rock pile, 10 ft, prime for fall. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| 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) |
| Été | 50 to 120 ft | dawn | Break off the point (53 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Rock reef (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Break off the point (53 ft) | White tube jig, Airplane jig |
Spring puts arctic char in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 20 to 60 ft; cold water stacks them in 10 to 40 ft. Rock reef is the standout, a rock pile at roughly 10 ft, rated prime for fall arctic char. Plan around early morning in the warm months. A jigging spoon vertical or a tube jig (smelt) covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | midday & dawn | Rivière Ouareau inflow (7 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Été | 20 to 60 ft | dawn | Break off the point (53 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Automne | 8 to 30 ft | midday & dusk | Rock reef (10 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Hiver | 10 to 40 ft | midday & dawn | Sharp break (33 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. Warm water sends them out to 40 to 90 ft; cold water stacks them in 25 to 70 ft. Rock reef is the standout, a rock pile at roughly 10 ft, rated prime for fall lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. The spot to know is Rivière Ouareau inflow, an inflow / creek mouth in about 7 ft of water that rates prime for walleye in spring. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Rivière Ouareau inflow (7 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 15 to 35 ft | dusk & dawn | Sharp break (33 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

| Hiver | 20 to 40 ft | dusk & dawn | Sharp break (33 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Spring yellow perch concentrate at Back-bay flat, a prime-rated weed flat around 9 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Back-bay flat (9 ft) | Small jig + curly tail, Perch-pattern micro crank |

| Automne | 12 to 35 ft | midday | Sharp break (33 ft) | Jigging spoon (small), Perch rig / spreader |
| Hiver | 15 to 35 ft | midday & dawn | Sharp break (33 ft) | Tungsten jig + spikes, Rattle spoon (small) |

Anglers target brook trout, lake trout, arctic char, lake whitefish, walleye, yellow perch, northern pike, smallmouth bass, rock bass, pumpkinseed, brown bullhead, channel catfish, burbot on Lac Ouareau. 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.
Rivière Ouareau inflow is the top-rated area: an inflow / creek mouth in about 7 ft of water that rates prime for brook trout in spring. Every other rated spot, per species and season, is on the map above.
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.
