58-acre lake near Québec. The lake tops out around 25 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 rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 58 acres of water rimmed by 1.4 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. 62% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.6 mi with a 0.2-mi widest point. The water lies in Matawinie MRC. The nearest mapped water is Lac Saint-Anselme, 2 mi to the southeast.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 8 to 25 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 25 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.

Early season walleye use the shallows, holding in 4 to 15 ft. Summer is an 8 to 25 ft game here, winter an 8 to 25 ft one.

Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

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.

Anglers target brook trout, walleye, yellow perch, northern pike, smallmouth bass, rock bass, pumpkinseed on Lac Saint-Pierre. 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 24 ft of water that rates prime for walleye in fall. The map above holds the full rated-spot list for every 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.
