6,728-acre lake near Québec. The lake tops out around 150 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. Here's the year, species by species, as the scoring engine sees it.
Lac des Commissaires maps at 6,729 acres behind 46.5 miles of shoreline. With a shoreline index of 4, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 30% of the surface — that's where the groceries are. The basin spans about 16.4 mi end to end and 3.2 mi across at its widest. It sits in Le Domaine-du-Roy MRC. Its nearest charted neighbour, Lac Prinzèles, is 3 mi to the east.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Start at Break off the point. It's a drop-off holding about 13 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.

Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
