181-acre lake near Québec. The lake tops out around 80 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.
Lac au Vison maps at 181 acres behind 3.1 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Roughly 29% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 1.3 mi end to end and 0.4 mi across at its widest. It sits in D'Autray MRC. Lac Cutaway sits 1 mi north — the closest neighbouring chart.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Break off the point. It's a drop-off holding about 28 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
