852-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. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Lac Mignault runs 852 acres with 7 miles of edge, with a single island in the mix. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. About 63% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 2.6 mi long by 1 mi wide at the broadest reach. You'll find it in Le Domaine-du-Roy MRC. The nearest mapped water is Lac des Cantons, 4 mi to the southeast.

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 Break off the point, a prime-rated drop-off around 8 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.

When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 8 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

It's a drop-off holding about 8 ft of water and rates prime come summer. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Break off the point, a drop-off in about 8 ft of water that rates prime for northern pike in fall. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
