Rating depth structure for brook trout.
Recent public catches load as you reach this section.
26-acre lake near Québec. The lake tops out around 11 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Lacs Gunn (no 4) maps at 26 acres behind 0.9 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 0.4 mi. La Matanie MRC claims this one. Its nearest charted neighbour, Lacs Gunn (no 1), is 1 mi to the east.

Early season brook trout use the shallows, holding in 1 to 11 ft. Even in summer they hold at 3 to 11 ft; winter keeps them in 2 to 11 ft. The chart's best answer is Deep basin — deep basin, 9 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.
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 11 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 3 to 11 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 1 to 11 ft chart-limited; documented 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Hiver | 2 to 11 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (9 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring landlocked salmon on Lacs Gunn (no 4) hold shallow, usually 1 to 11 ft. Depth-wise the year is flat: 3 to 11 ft in summer, 3 to 11 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 9 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a dodger + streamer down deep or a thin spoon on lead core.

Anglers target brook trout, landlocked salmon on Lacs Gunn (no 4). 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 9 ft of water that rates prime for landlocked salmon in summer. 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.
