23-acre lake near Québec. The lake tops out around 23 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 season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Lac Prévost runs 23 acres with 0.7 miles of edge. 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. The shallow band under 15 ft claims about 86% of the surface — that's where the groceries are. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. You'll find it in Matawinie MRC. For a second option, Lac à l'Île lies 0 mi north.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 7 to 23 ft, and winter fish settle into 3 to 20 ft. The spot to know is Deep basin, a deep basin in about 23 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
