Rating depth structure for brook trout.

43-acre lake near Québec. The lake tops out around 10 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Lacs Gunn (no 1) draws 43 acres inside 1 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.4 mi end to end and 0.3 mi across at its widest. The water lies in La Matanie MRC. Closest neighbour on DepthScout: Lacs Gunn (no 4), 1 mi west of here.

Start shallow in spring: brook trout sit in 1 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 2 to 10 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 10 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
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 10 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 3 to 10 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 1 to 10 ft chart-limited; documented 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Hiver | 2 to 10 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (10 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: landlocked salmon in 1 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 landlocked salmon in summer. Plan around early morning and the evening in the warm months. Summer baits: a dodger + streamer down deep or a thin spoon on lead core gets it done.
