23-acre lake near Québec. The lake tops out around 56 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. Species by species, here's what the data says the year looks like.
On the chart, Lac Gentil draws 23 acres inside 0.8 miles of shoreline. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 34% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 0.3 mi, about 0.2 mi across. You'll find it in Maskinongé MRC. Closest neighbour on DepthScout: Lac de la Corneille, 1 mi south of here.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Winter brook trout concentrate at Shoreline break, a prime-rated drop-off around 7 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.

In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 17 to 56 ft before dropping to 14 to 56 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 54 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
