76-acre lake near Québec. The lake tops out around 26 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. What the data behind the map says about each species, season by season:
The outline encloses 76 acres, worked by 1.3 miles of shoreline. A shoreline index of 1 says round and simple: fish relate to depth changes here, not shoreline features. The shallow band under 15 ft claims about 92% of the surface — that's where the groceries are. The basin spans about 0.5 mi end to end and 0.3 mi across at its widest. La Côte-de-Beaupré MRC claims this one. If the bite dies, Lac Lachance is 3 mi to the west.
