49-acre lake near Québec. The lake tops out around 13 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.
Drawn out, this is 49 acres of water rimmed by 1.1 miles of bank. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Matawinie MRC. The nearest mapped water is Lac Herman, 1 mi to the southeast.

Start shallow in spring: brook trout sit in 2 to 13 ft that time of year. They don't go far with the seasons — 4 to 13 ft covers summer, 2 to 13 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 13 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.

|---|---|---|---|---|
| Printemps | 2 to 13 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |

Early season walleye use the shallows, holding in 3 to 13 ft. Even in summer they hold at 4 to 13 ft; winter keeps them in 4 to 13 ft. The chart's best answer is Break off the point — drop-off, 9 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

Spring yellow perch on Lac Trap hold shallow, usually 3 to 12 ft. By summer they slide out to 4 to 13 ft, and by winter most fish are in 4 to 13 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 4 to 13 ft, wintering in 4 to 13 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.

Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 4 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.

When the water first warms, rock bass slide up into 2 to 10 ft. By summer they slide out to 3 to 13 ft, and by winter most fish are in 4 to 13 ft. If you only fish one area, make it Main-lake point: a point around 4 ft that scores prime in summer. In summer the feeding windows fall in the evening. Keep a ned rig (small) or a marabou jig rigged through the warm months.

Anglers target brook trout, walleye, yellow perch, northern pike, smallmouth bass, rock bass, pumpkinseed, brown bullhead on Lac Trap. 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.
Break off the point is the top-rated area: a drop-off in about 9 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.
