1,279-acre lake near Québec. The lake tops out around 50 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. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 1,279 acres of water rimmed by 6.4 miles of bank. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 16% of this chart. Figure 2.3 mi of water from one end to the other, 1.6 mi at the beam. The water lies in Papineau MRC. The nearest mapped water is Lac Hawk, 6 mi to the north.

The spring pattern is a shallow one: lake trout in 10 to 40 ft. As the season builds they drop to 15 to 50 ft, wintering in 13 to 50 ft. Top water on the chart: Deep basin, a deep basin in the 50 ft range, prime in summer. Time it for early morning. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Break off the point (20 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 15 to 50 ft | dawn | Deep basin (50 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Secondary point (7 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 13 to 50 ft | dawn | Deep basin (50 ft) | White tube jig, Airplane jig |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 20 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (5 ft) | Inline spinner (silver), Small spoon |

Spring brown trout on Lac la Blanche hold shallow, usually 3 to 25 ft. They move out to 15 to 50 ft in summer and finish the year down in 5 to 35 ft. Put Break off the point first on the milk run — a drop-off near 20 ft that grades prime for summer. The feeding windows run after dark and early morning. The summer box starts with a spoon at the thermocline or a deep stickbait (night).
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |

| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (5 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |

Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. Expect a summer slide to 15 to 50 ft, then a winter hold in 15 to 50 ft. Start at Deep basin. It's a deep basin holding about 50 ft of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Break off the point (20 ft) | Small jig + waxworm, Blade bait (small) |

Spring walleye on Lac la Blanche hold shallow, usually 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. Put Break off the point first on the milk run — a drop-off near 20 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (5 ft) | 1/8 oz jig + minnow, Hair jig |

Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Put Break off the point first on the milk run — a drop-off near 20 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
