126-acre lake near Québec. The lake tops out around 60 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. Species by species, here's what the data says the year looks like.
The drawn water covers 126 acres wrapped in 3 miles of bank. A middling shoreline index (1.9) gives it some bays to work without being a maze. Roughly 21% 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 0.3 mi across. It sits in La Vallée-de-la-Gatineau MRC. If the bite dies, Lac Andon is 2 mi to the northeast.

When the water first warms, brook trout slide up into 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. If you only fish one area, make it Shallow bay flat: a weed flat around 8 ft that scores good in spring. In summer the feeding windows fall in 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 | Shallow bay flat (8 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 | Main-lake point (19 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (8 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 18 to 60 ft, then a winter hold in 15 to 60 ft. Put Deep basin first on the milk run — a deep basin near 60 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.

Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 18 to 60 ft, wintering in 18 to 60 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 60 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.

Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 18 to 60 ft, wintering in 20 to 60 ft. Summer cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 60 ft. Warm-month bites cluster around early morning. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Main-lake point, a point in the 19 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 8 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

Anglers target brook trout, lake trout, lake whitefish, cisco (lake herring), walleye, yellow perch, northern pike, smallmouth bass, rock bass, pumpkinseed, burbot on Lac Coupal. 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 60 ft of water that rates prime for lake trout in summer. 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.
