54-acre lake near Québec. The lake tops out around 33 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 is how the season plays out for each species, straight from the data behind the map.
The outline encloses 54 acres, worked by 1.4 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline.
