148-acre lake near Québec. The lake tops out around 98 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. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 148 acres wrapped in 2.6 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. About 13% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 1.2 mi of water from one end to the other, 0.3 mi at the beam. It sits in Maskinongé MRC. If the bite dies, Lac Brodeur is 2 mi to the northwest.

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 Main-lake point. It's a point holding about 13 ft of water and rates prime come spring. 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.

The spot to know is Main-lake point, a point in about 13 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
