220-acre lake near Québec. The lake tops out around 90 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.
Drawn out, this is 220 acres of water rimmed by 2.5 miles of bank. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 18% of this chart. Figure 1.1 mi of water from one end to the other, 0.4 mi at the beam. The water lies in La Haute-Gaspésie MRC.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Spring brook trout concentrate at Main-lake point, a prime-rated point around 6 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

Spring puts landlocked salmon in skinny water — 1 to 15 ft is the zone. Warm water sends them out to 25 to 60 ft; cold water stacks them in 10 to 40 ft.

A dodger + streamer down deep or a thin spoon on lead core covers the summer program.
