720-acre lake near Québec. The lake tops out around 148 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. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Lac Masson runs 720 acres with 5.6 miles of edge. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. The shallow band under 15 ft claims about 8% of the surface — that's where the groceries are. Call it 1.7 mi long by 1.3 mi wide at the broadest reach. You'll find it in Les Pays-d'en-Haut MRC. For a second option, Lac du Nord lies 1 mi northeast.

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 50 to 120 ft; cold water stacks them in 20 to 80 ft. Main-lake point is the standout, a point at roughly 15 ft, rated prime for spring lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
