260-acre lake near Québec. The lake tops out around 39 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. Species by species, here's what the data says the year looks like.
The outline encloses 260 acres, worked by 2.7 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. About 45% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 0.9 mi with a 0.8-mi widest point. It sits in Antoine-Labelle MRC. Its nearest charted neighbour, Petit lac Nominingue, is 2 mi to the west.

Spring brook trout on Lac Blanc hold shallow, usually 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. The chart's best answer is Break off the point — drop-off, 31 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (12 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (31 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (12 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Shallow bay flat (4 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season landlocked salmon use the shallows, holding in 1 to 15 ft. Expect a summer slide to 12 to 39 ft, then a winter hold in 10 to 39 ft. Put Deep basin first on the milk run — a deep basin near 39 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + streamer down deep or a thin spoon on lead core and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | Main-lake point (12 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Été | 12 to 39 ft | dawn & dusk | Deep basin (39 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Automne | 5 to 30 ft | dawn & dusk | Main-lake point (12 ft) | Casting spoon at the mouths, Streamers |
| Hiver | 10 to 39 ft | dawn | Deep basin (39 ft) | Small jigging spoon, Swedish pimple + smelt |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 15 to 35 ft; cold water stacks them in 12 to 39 ft. Break off the point is the standout, a drop-off at roughly 31 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (12 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 15 to 35 ft | dusk & dawn | Break off the point (31 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 12 to 39 ft | dusk & night | Break off the point (31 ft) | Jigging rap, Jig + big minnow |
| Hiver | 12 to 39 ft | dusk & dawn | Deep basin (39 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 4 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 10 to 30 ft | dawn | Break off the point (31 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Automne | 12 to 35 ft | midday | Break off the point (31 ft) | Jigging spoon (small), Perch rig / spreader |
| Hiver | 15 to 35 ft | midday & dawn | Deep basin (39 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |

| Automne | 6 to 18 ft | midday & dawn | Back-bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Hiver | 5 to 15 ft | midday | Back-bay flat (6 ft) | Tip-ups, Large jigging spoon |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 12 to 39 ft. If you only fish one area, make it Main-lake point: a point around 12 ft that scores prime in fall. Best bite is early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | dawn & dusk | Main-lake point (12 ft) | Ned rig, Tube jig |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (31 ft) | Drop shot (goby/minnow), Ned rig |
| Automne | 8 to 25 ft | midday & dawn | Main-lake point (12 ft) | Jerkbait, Blade bait |
| Hiver | 12 to 39 ft | midday | Break off the point (31 ft) | Blade bait, Hair jig |
