314-acre lake near Québec. The lake tops out around 105 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 314 acres of water rimmed by 3 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. 13% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 1.1 mi of water from one end to the other, 0.7 mi at the beam. The water lies in Les Laurentides MRC. Closest neighbour on DepthScout: Lac Gélinas, 1 mi southeast of here.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Main-lake point is the standout, a point at roughly 7 ft, rated prime for spring brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
