1,729-acre lake near Québec. The lake tops out around 66 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. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 1,729 acres of water rimmed by 11.1 miles of bank. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 69% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 5.2 mi with a 1-mi widest point. You'll find it in Rimouski-Neigette MRC. Closest neighbour on DepthScout: Petit lac Touradi, 2 mi north of here.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Break off the point, a drop-off in about 31 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.
