279-acre lake near Québec. The lake tops out around 10 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. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 279 acres, worked by 2.8 miles of shoreline. Nearly circular (index 1.2), so the story is the bottom, not the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. The basin spans about 1.2 mi end to end and 0.5 mi across at its widest. It sits in Montmagny MRC. Its nearest charted neighbour, Presley Lake, is 4 mi to the east.

Early season brook trout use the shallows, holding in 1 to 10 ft. Even in summer they hold at 3 to 10 ft; winter keeps them in 2 to 10 ft. Put Deep basin first on the milk run — a deep basin near 10 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 10 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 3 to 10 ft | dawn & dusk | Deep basin (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

| Hiver | 2 to 10 ft | dawn | Deep basin (10 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: yellow perch in 3 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. The spot to know is Deep basin, a deep basin in about 10 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

| Printemps | 3 to 10 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |

Come spring, look for muskellunge tight to the bank in 3 to 10 ft. Through summer count on 3 to 10 ft; the winter hold is 3 to 10 ft. Start at Break off the point. It's a drop-off holding about 6 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A double-10 bucktail or a topwater (walk-the-dog / creeper) is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 10 ft | dusk | Shallow bay flat (2 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Été | 3 to 10 ft | dusk & dawn | Break off the point (6 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Automne | 3 to 10 ft | midday & dusk | Break off the point (6 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Hiver | 3 to 10 ft | midday | Deep basin (10 ft) | Large rubber, crawled slow |
When the water first warms, smallmouth bass slide up into 3 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 3 to 10 ft. Start at Break off the point. It's a drop-off holding about 6 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 10 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |

Anglers target brook trout, yellow perch, muskellunge, smallmouth bass, brown bullhead on Lac Frontière. 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 10 ft of water that rates prime for yellow perch 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.
