29-acre lake near Québec. The lake tops out around 25 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. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 29 acres wrapped in 0.8 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. About 64% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. It sits in Papineau MRC. Its nearest charted neighbour, Lac Dumas, is 1 mi to the southeast.

Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
