20-acre lake near Québec. The lake tops out around 15 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. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 20 acres wrapped in 0.7 miles of bank. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. It sits in La Vallée-de-la-Gatineau MRC. Its nearest charted neighbour, Lac de la File, is 1 mi to the east.

Early season brook trout use the shallows, holding in 2 to 15 ft. Even in summer they hold at 5 to 15 ft; winter keeps them in 2 to 15 ft. Put Deep basin first on the milk run — a deep basin near 15 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.

You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
