2,234-acre lake near Québec. The lake tops out around 160 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.
Traced from the shoreline, Lac du Sourd runs 2,234 acres with 13.4 miles of edge. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. 5% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 3.4 mi end to end and 2.2 mi across at its widest. You'll find it in Antoine-Labelle MRC. The nearest mapped water is Lac Castilly, 2 mi to the north.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 20 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.

Break off the point is the standout, a drop-off at roughly 20 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
