83-acre lake near Québec. The lake tops out around 75 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.
Traced from the shoreline, Lac Pierre-Aubin runs 83 acres with 1.7 miles of edge. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline.
