657-acre lake near Québec. The lake tops out around 46 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.
The drawn water covers 657 acres wrapped in 5.7 miles of bank — one island included. With a 1.6 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 31% of this chart. Tip to tip the water measures near 2.2 mi with a 0.8-mi widest point. La Côte-de-Beaupré MRC claims this one. Its nearest charted neighbour, Lac Magny, is 2 mi to the southwest.

Spring brook trout on Lac aux Montagnais hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 18 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.

Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 18 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
