400-acre lake near Québec. The lake tops out around 131 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. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 400 acres, worked by 4.6 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. Roughly 34% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 1.8 mi, about 0.8 mi across. Matawinie MRC claims this one. 9e Lac sits 2 mi northeast — the closest neighbouring chart.
