499-acre lake near Québec. The lake tops out around 148 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.
The outline encloses 499 acres, worked by 6.7 miles of shoreline. A middling shoreline index (2.1) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 4% of the surface — that's where the groceries are. Tip to tip the water measures near 3.1 mi with a 0.6-mi widest point. Mékinac MRC claims this one. Its nearest charted neighbour, Lac du Jésuite, is 3 mi to the west.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Secondary point: a point around 16 ft that scores prime in spring. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
