14-acre lake near Québec. The lake tops out around 33 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 14 acres, worked by 0.7 miles of shoreline. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. 29% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.3 mi. Sept-Rivières--Caniapiscau claims this one. Lac en Corbeille sits 0 mi north — the closest neighbouring chart.

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 Deep basin — deep basin, 33 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.
