17-acre lake near Québec. The lake tops out around 80 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. Species by species, here's what the data says the year looks like.
The outline encloses 17 acres, worked by 0.8 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. 2% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 0.4 mi long. Les Laurentides MRC claims this one. If the bite dies, Lac Tador is 2 mi to the northeast.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
