When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Ruisseau Jourdain inflow: an inflow / creek mouth around 1 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Ruisseau Jourdain inflow (1 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Ruisseau Jourdain inflow (1 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Ruisseau Jourdain inflow (1 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Ruisseau Jourdain inflow (1 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 119 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Sharp break (4 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Deep basin (119 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (1 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Sharp break (4 ft) | White tube jig, Airplane jig |
Come spring, look for landlocked salmon tight to the bank in 1 to 15 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 10 to 40 ft. Start at Ruisseau Jourdain inflow. It's an inflow / creek mouth holding about 1 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A dodger + streamer down deep or a thin spoon on lead core is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Ruisseau Jourdain inflow (1 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Été | 25 to 60 ft | dawn & dusk | Deep basin (119 ft) | Dodger + streamer down deep, Thin spoon on lead core |

| Hiver | 10 to 40 ft | dawn | Sharp break (4 ft) | Small jigging spoon, Swedish pimple + smelt |
Spring puts arctic char in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 20 to 60 ft, wintering in 10 to 40 ft. Spring arctic char concentrate at Sharp break, a prime-rated drop-off around 4 ft. Warm-month bites cluster around early morning. A jigging spoon vertical or a tube jig (smelt) covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | midday & dawn | Sharp break (4 ft) | Small casting spoon (silver/orange), Jerkbait (small) |

Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Spring lake whitefish concentrate at Feeding flat, a prime-rated feeding flat around 33 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.

| Printemps | 15 to 45 ft | midday & dawn | Feeding flat (33 ft) | Small jig + waxworm, Blade bait (small) |

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Ruisseau Jourdain inflow, an inflow / creek mouth in the 1 ft range, prime in spring. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |

| Printemps | 4 to 15 ft | dusk & dawn | Ruisseau Jourdain inflow (1 ft) | 1/8 oz jig + minnow, Hair jig |
