19-acre lake near Québec. The lake tops out around 20 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 19 acres of water rimmed by 0.8 miles of bank. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. The shallow band under 15 ft claims about 82% of the surface — that's where the groceries are. End to end it runs roughly 0.3 mi. You'll find it in Argenteuil MRC. Closest neighbour on DepthScout: Lac Paul, 1 mi northeast of here.
