47-acre lake near Québec. The lake tops out around 25 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.
Traced from the shoreline, Petit lac du Rat Musqué runs 47 acres with 1.4 miles of edge. Its 1.4 shoreline index means few bank features; the contours below do the pattern work.
