30-acre lake near Québec. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
On the chart, Lac Long draws 30 acres inside 1.4 miles of shoreline. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 74% of this chart. The basin spans about 0.7 mi end to end. You'll find it in Mékinac MRC. Closest neighbour on DepthScout: Lac du Rocher, 1 mi east of here.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 6 to 20 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 20 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 6 to 20 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 6 to 20 ft, and by winter most fish are in 6 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 20 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.

When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 6 to 20 ft game here, winter a 6 to 20 ft one. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. 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 4 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.
