133-acre lake near Québec. The lake tops out around 30 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.
Drawn out, this is 133 acres of water rimmed by 2.2 miles of bank, with a single island in the mix. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 66% of the water is 15 ft or less, the band where the food chain lives. Figure 1 mi of water from one end to the other, 0.3 mi at the beam. You'll find it in Mékinac MRC. The nearest mapped water is Lac Dévié, 1 mi to the northeast.

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. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 29 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.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |

When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 9 to 30 ft, and by winter most fish are in 9 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 29 ft that scores prime in winter. 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 deep basin holding about 29 ft of water and rates prime come fall. 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 Shallow bay flat, a weed flat in about 1 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
