32-acre lake near Québec. The lake tops out around 7 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. What the data behind the map says about each species, season by season:
Lac Demaux maps at 32 acres behind 0.9 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. Le Saguenay-et-son-Fjord claims this one. Its nearest charted neighbour, Lac Yvette, is 0 mi to the north.

Early season brook trout use the shallows, holding in 1 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 1 to 7 ft. The chart's best answer is Deep basin — deep basin, 7 ft, prime for summer. Best bite is 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 7 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 2 to 7 ft | dawn & dusk | Deep basin (7 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 1 to 7 ft | midday & dawn | open water | Small spoon (orange), Spinner |

Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
