28-acre lake near Québec. The lake tops out around 10 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. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 28 acres wrapped in 0.9 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. Mékinac MRC claims this one. If the bite dies, Lac Thom is 1 mi to the northeast.

Spring brook trout on Lac du Diablotin hold shallow, usually 1 to 10 ft. Depth-wise the year is flat: 3 to 10 ft in summer, 2 to 10 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 10 ft that grades prime for summer. The feeding windows run 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 | 1 to 10 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 3 to 10 ft | dawn & dusk | Deep basin (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

| Hiver | 2 to 10 ft | dawn | Deep basin (10 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season landlocked salmon use the shallows, holding in 1 to 10 ft. Even in summer they hold at 3 to 10 ft; winter keeps them in 3 to 10 ft. The chart's best answer is Deep basin — deep basin, 10 ft, prime for summer. Best bite is 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 10 ft | dawn & dusk | Main-lake point (5 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |

Spring puts walleye in skinny water — 3 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 3 to 10 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 7 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 10 ft | dusk & dawn | Main-lake point (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 3 to 10 ft | dusk & dawn | Break off the point (7 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 3 to 10 ft | dusk & night | Break off the point (7 ft) | Jigging rap, Jig + big minnow |
| Hiver | 3 to 10 ft | dusk & dawn | Deep basin (10 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 3 to 10 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. 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 10 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 3 to 10 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Automne | 3 to 10 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Hiver | 3 to 10 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 3 to 10 ft, then a winter hold in 3 to 10 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in 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 (3 ft) | #5 inline spinner, Spoon (red/white) |

| Automne | 3 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
