629-acre lake near Québec. The lake tops out around 140 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.
The outline encloses 629 acres, worked by 8.9 miles of shoreline. An index of 2.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Roughly 12% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 3.9 mi, about 0.9 mi across. Papineau MRC claims this one. Its nearest charted neighbour, Lac Campeau, is 1 mi to the east.
