66-acre lake near Québec. The lake tops out around 65 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 follows comes from the same scoring engine that paints the spots above.
Lac Gauthier maps at 66 acres behind 1.3 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. Roughly 8% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 0.5 mi end to end and 0.3 mi across at its widest. Maskinongé MRC claims this one. Its nearest charted neighbour, Lac Shawinigan, is 1 mi to the southeast.

Spring brook trout on Lac Gauthier hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Shallow bay flat first on the milk run — a feeding flat near 11 ft that grades good for spring. 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 | 2 to 15 ft | dawn & dusk | Shallow bay flat (11 ft) | Small inline spinner (gold), Tiny spoon |

| Hiver | 3 to 20 ft | dawn | Shallow bay flat (11 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 20 to 65 ft in summer and finish the year down in 16 to 65 ft. If you only fish one area, make it Deep basin: a deep basin around 62 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 10 to 40 ft | dawn & dusk | Main-lake point (22 ft) | Casting spoon over shoals, Jerkbait (shallow) |

The spring pattern is a shallow one: arctic char in 4 to 15 ft. Midsummer fish sit out in 20 to 60 ft before dropping to 10 to 40 ft for winter. The spot to know is Deep basin, a deep basin in about 62 ft of water that rates prime for arctic char in summer. Plan around early morning in the warm months. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.

The spot to know is Deep basin, a deep basin in about 62 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.

Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Fall walleye concentrate at Main-lake point, a prime-rated point around 22 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.

|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | open water | 1/8 oz jig + minnow, Hair jig |

The spot to know is Shallow bay flat, a feeding flat in about 11 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.
