316-acre lake near Québec. The lake tops out around 23 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.
The outline encloses 316 acres, worked by 3.1 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. About 54% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 1.2 mi end to end and 0.8 mi across at its widest. Rouyn-Noranda claims this one. Lac Vose sits 7 mi northeast — the closest neighbouring chart.
