9-acre lake near Québec. The lake tops out around 59 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, Lac Dorothy runs 9 acres with 0.5 miles of edge. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. The shallow band under 15 ft claims about 24% of the surface — that's where the groceries are. You'll find it in La Côte-de-Beaupré MRC. The nearest mapped water is Lac Roy, 3 mi to the east.
