86-acre lake near Québec. The lake tops out around 17 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. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 86 acres wrapped in 1.7 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 95% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 0.8 mi, about 0.3 mi across. La Matanie MRC claims this one. If the bite dies, Lac Behrend is 3 mi to the northwest.

Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 5 to 17 ft game here, winter a 3 to 17 ft one. The chart's best answer is Deep basin — deep basin, 17 ft, prime for summer. Best bite is 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.
