15-acre lake near Québec. The lake tops out around 40 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.
Drawn out, this is 15 acres of water rimmed by 0.7 miles of bank. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 17% of the surface — that's where the groceries are. Call it 0.3 mi long. The water lies in La Côte-de-Beaupré MRC. For a second option, Lac Walsh lies 1 mi north.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft.
