298-acre lake near Québec. The lake tops out around 131 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 298 acres of water rimmed by 2.9 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. About 2% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 1.2 mi end to end and 0.6 mi across at its widest. You'll find it in Antoine-Labelle MRC. The nearest mapped water is Lac Saint-Denis, 2 mi to the southwest.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Shallow bay flat is the standout, a feeding flat at roughly 14 ft, rated good for spring brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

Main-lake point is the top-rated area: a point in about 25 ft of water that rates prime for lake trout in spring. Scroll up to the map for the complete spot list by 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.
