257-acre lake near Québec. The lake tops out around 30 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.
Drawn out, this is 257 acres of water rimmed by 3.3 miles of bank. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. The shallow band under 15 ft claims about 40% of the surface — that's where the groceries are. The basin spans about 1.3 mi end to end and 0.6 mi across at its widest. The water lies in Matawinie MRC. Closest neighbour on DepthScout: Lac Cristal, 4 mi south of here.

In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 6 to 30 ft for winter. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 21 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
