17-acre lake near Québec. The lake tops out around 33 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. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Lac Saint-Louis runs 17 acres with 0.6 miles of edge. Nearly circular (index 1.1), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 36% of the surface — that's where the groceries are. You'll find it in Les Pays-d'en-Haut MRC. The nearest mapped water is Lac Grothé, 1 mi to the west.

Top water on the chart: Break off the point, a drop-off in the 28 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
