11-acre lake near Québec. The lake tops out around 20 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. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Lac de la Montagne runs 11 acres with 0.5 miles of edge. Nearly circular (index 1.1), so the story is the bottom, not the bank. Roughly 71% of the water is 15 ft or less, the band where the food chain lives. You'll find it in Argenteuil MRC. Closest neighbour on DepthScout: Lac Crooks, 2 mi southeast of here.
