71-acre lake near Québec. The lake tops out around 45 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. Below is the species-by-species picture, pulled from the same data the map uses.
Lac Fortier maps at 71 acres behind 1.2 miles of shoreline. A shoreline index of 1 says round and simple: fish relate to depth changes here, not shoreline features. About 38% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.4 mi end to end and 0.4 mi across at its widest. It sits in Charlevoix MRC. Lac Decoigne sits 1 mi southeast — the closest neighbouring chart.
Carte de pêche interactive gratuite — Lac Fortier, Québec : courbes de profondeur issues de relevés bathymétriques réels jusqu'à 14 m (45 pi), et les meilleurs sites pour omble de fontaine et perchaude.

Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades good for spring. 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 | 2 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. The spot to know is Back-bay flat, a weed flat in about 10 ft of water that rates prime for yellow perch in spring. 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.
