14-acre lake near Québec. The lake tops out around 13 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. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 14 acres wrapped in 0.6 miles of bank. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Call it 0.3 mi long. La Rivière-du-Nord MRC claims this one. Its nearest charted neighbour, Lac Montaubois, is 0 mi to the north.
