430-acre lake near Québec. The lake tops out around 180 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.
Drawn out, this is 430 acres of water rimmed by 3.5 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 3% of the surface — that's where the groceries are. The basin spans about 1.2 mi end to end and 0.9 mi across at its widest. You'll find it in Matawinie MRC. For a second option, Lac Saint-Grégoire lies 2 mi northwest.

The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Secondary point, a point in the 14 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
