124-acre lake near Québec. The lake tops out around 56 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 the data behind the map says about each species, season by season:
Traced from the shoreline, Lac Saint-Pierre runs 124 acres with 3.3 miles of edge. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. About 26% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1.6 mi long by 0.2 mi wide at the broadest reach. You'll find it in Kamouraska MRC. The nearest mapped water is Lac de l'Est, 22 mi to the southeast.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Main-lake point is the standout, a point at roughly 7 ft, rated prime for spring brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 17 to 56 ft; cold water stacks them in 14 to 56 ft. Deep basin is the standout, a deep basin at roughly 53 ft, rated prime for summer 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.
