18-acre lake near Québec. The lake tops out around 5 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Lac du Pont de Bois draws 18 acres inside 0.7 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 0.3 mi. The water lies in Portneuf MRC. The nearest mapped water is Lac Main de Fer, 1 mi to the southeast.

Spring puts brook trout in skinny water — 1 to 5 ft is the zone. Summer fish stay in 2 to 5 ft, and winter fish hold in 1 to 5 ft. Deep basin is the standout, a deep basin at roughly 5 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. 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 | 1 to 5 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 2 to 5 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (5 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 1 to 5 ft chart-limited; documented 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Hiver | 1 to 5 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (5 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, walleye slide up into 1 to 5 ft. There's no big seasonal slide here — summer means 2 to 5 ft, winter 2 to 5 ft. Start at Deep basin. It's a deep basin holding about 5 ft of water and rates prime come winter. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 5 ft chart-limited; documented 4 to 15 ft | dusk & dawn | open water | 1/8 oz jig + minnow, Hair jig |

When the water first warms, yellow perch slide up into 1 to 5 ft. There's no big seasonal slide here — summer means 2 to 5 ft, winter 2 to 5 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in 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 1 to 5 ft. The depth story barely changes: 2 to 5 ft through summer, 2 to 5 ft in winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

Anglers target brook trout, walleye, yellow perch, northern pike on Lac du Pont de Bois. 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.
Deep basin is the top-rated area: a deep basin in about 5 ft of water that rates prime for walleye in winter. The map above holds the full rated-spot list for every 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.
