41-acre lake near Québec. The lake tops out around 49 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.
Traced from the shoreline, Lac Troie runs 41 acres with 1 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 32% of the surface — that's where the groceries are. End to end it runs roughly 0.4 mi, about 0.2 mi across. You'll find it in Antoine-Labelle MRC. For a second option, Étang Java lies 1 mi northwest.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Shallow bay flat, a weed flat in about 7 ft of water that rates good for brook trout in spring. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.

Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
