500-acre lake near Québec. The lake tops out around 60 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 500 acres, worked by 4.8 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. Roughly 40% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 2 mi end to end and 0.7 mi across at its widest. Rimouski-Neigette MRC claims this one. If the bite dies, Petit lac Kedgwick is 2 mi to the north.

Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Break off the point — drop-off, 15 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
