207-acre lake near Québec. The lake tops out around 30 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Drawn out, this is 207 acres of water rimmed by 2.5 miles of bank. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. 53% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 1 mi of water from one end to the other, 0.6 mi at the beam. You'll find it in Portneuf MRC. The nearest mapped water is Lac Main de Fer, 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 30 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Deep basin (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (6 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 9 to 30 ft, and by winter most fish are in 9 to 30 ft. If you only fish one area, make it Break off the point: a drop-off around 29 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.
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 | 4 to 15 ft | dusk & dawn | Main-lake point (10 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 9 to 30 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (29 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 9 to 30 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (29 ft) | Jigging rap, Jig + big minnow |
| Hiver | 9 to 30 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (30 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 9 to 30 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 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.

| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 10 to 30 ft | dawn | Deep basin (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Automne | 9 to 30 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (30 ft) | Jigging spoon (small), Perch rig / spreader |
| Hiver | 9 to 30 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
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 6 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Été | 8 to 20 ft | dawn & dusk | Back-bay flat (7 ft) | Bucktail, Weedless spoon over cabbage |
| Automne | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Hiver | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |

Le Bon Lac is about 30 ft (9 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Le Bon Lac atteint environ 9 m (30 pi) à son point le plus profond. Les profondeurs proviennent de relevés bathymétriques réels.
Anglers target brook trout, walleye, yellow perch, northern pike on Le Bon Lac. This species list is an informed estimate from Québec's provincial fish-range maps (bounded by each lake's depth and habitat), not a per-lake fish survey — Québec doesn't publish per-lake species records.
Break off the point is the top-rated area: a drop-off in about 29 ft of water that rates prime for walleye in fall. Open the map above to see every rated spot for each species and season.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
