56-acre lake near Québec. The lake tops out around 69 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. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Lac Roche draws 56 acres inside 1.1 miles of shoreline, with a single island in the mix. Nearly circular (index 1.1), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 28% of this chart. Figure 0.4 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Charlevoix MRC. The nearest mapped water is Petit lac des Bois Verts, 1 mi to the southeast.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 24 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 21 to 69 ft, wintering in 17 to 69 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 69 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.

Early season arctic char use the shallows, holding in 4 to 15 ft. Expect a summer slide to 20 to 60 ft, then a winter hold in 10 to 40 ft. Put Break off the point first on the milk run — a drop-off near 24 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a jigging spoon vertical or a tube jig (smelt) and you're in the game.

Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Start at Break off the point. It's a drop-off holding about 24 ft of water and rates prime come summer. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
