1,114-acre lake near Québec. The lake tops out around 246 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. What the data behind the map says about each species, season by season:
The drawn water covers 1,114 acres wrapped in 10.7 miles of bank. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 14% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 4.1 mi of water from one end to the other, 1.4 mi at the beam. Manicouagan MRC claims this one. If the bite dies, Lac Rond is 3 mi to the north.

Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Secondary point: a point around 15 ft that scores prime in spring. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Secondary point (15 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Secondary point (15 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (9 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring lake trout on Lac Blanc hold shallow, usually 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. Put Main-lake point first on the milk run — a point near 19 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Break off the point (128 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Main-lake point (19 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Deep basin (240 ft) | White tube jig, Airplane jig |
When the water first warms, landlocked salmon slide up into 1 to 15 ft. Summer is a 25 to 60 ft game here, winter a 10 to 40 ft one. Start at Secondary point. It's a point holding about 15 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a dodger + streamer down deep or a thin spoon on lead core rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Secondary point (15 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Été | 25 to 60 ft | dawn & dusk | Deep basin (240 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Automne | 5 to 30 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon at the mouths, Streamers |
| Hiver | 10 to 40 ft | dawn | Main-lake point (19 ft) | Small jigging spoon, Swedish pimple + smelt |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 40 to 90 ft before dropping to 25 to 70 ft for winter. Spring lake whitefish concentrate at Back-bay flat, a prime-rated feeding flat around 15 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Back-bay flat (15 ft) | Small jig + waxworm, Blade bait (small) |
| Été | 40 to 90 ft | dawn | Shallow feeding flat (60 ft) | Blade bait vertical, Small jigging spoon |
| Automne | 8 to 30 ft | dusk | Main-lake point (19 ft) | Small spoon (gold), Jig + plastic larva |
| Hiver | 25 to 70 ft | midday & dawn | Shallow feeding flat (60 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. Shallow bay flat is the standout, a feeding flat at roughly 9 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (9 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 10 to 30 ft | dawn | Back-bay flat (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Automne | 12 to 35 ft | midday | Deep basin (240 ft) | Jigging spoon (small), Perch rig / spreader |
| Hiver | 15 to 35 ft | midday & dawn | Back-bay flat (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a feeding flat near 9 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 8 ft | midday & dawn | Shallow bay flat (9 ft) | #5 inline spinner, Spoon (red/white) |

Main-lake point is the top-rated area: a point in about 19 ft of water that rates prime for lake trout in spring. Open the map above to see every rated spot for each 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.
