37-acre lake near Québec. The lake tops out around 33 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Drawn out, this is 37 acres of water rimmed by 1 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. About 48% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. The water lies in La Matanie MRC. The nearest mapped water is Étang de la Montagne, 2 mi to the northwest.
Carte de pêche interactive gratuite — Lac du Gros Ruisseau, Québec : courbes de profondeur issues de relevés bathymétriques réels jusqu'à 10 m (33 pi), et les meilleurs sites pour omble de fontaine et ouananiche. Les profondeurs proviennent de la Géobase des bathymétries de lac du Québec (MELCCFP) lorsque disponibles.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 31 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.
| 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 | Deep basin (31 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Back-bay flat (5 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: landlocked salmon in 1 to 15 ft. Midsummer fish sit out in 10 to 33 ft before dropping to 8 to 33 ft for winter. The spot to know is Deep basin, a deep basin in about 31 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.
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 15 ft | dawn & dusk | open water | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Été | 10 to 33 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Deep basin (31 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Automne | 5 to 30 ft | dawn & dusk | open water | Casting spoon at the mouths, Streamers |
| Hiver | 8 to 33 ft chart-limited; documented 10 to 40 ft | dawn | Deep basin (31 ft) | Small jigging spoon, Swedish pimple + smelt |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 31 ft.
