463-acre lake near Québec. The lake tops out around 31 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. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Lac Pontbriand draws 463 acres inside 8.6 miles of shoreline. A development index of 2.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. 94% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 3.9 mi, about 0.7 mi across. You'll find it in Matawinie MRC. The nearest mapped water is Lac Clair, 3 mi to the northwest.

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 6 to 31 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 8 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Secondary point (10 ft) | Inline spinner (silver), Small spoon |
| Été | 8 to 30 ft | dawn & dusk | Break off the point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Automne | 9 to 31 ft | dawn & dusk | Secondary point (10 ft) | Casting spoon, Jerkbait over shoals |
| Hiver | 6 to 31 ft | dawn | Break off the point (8 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for brown trout tight to the bank in 3 to 25 ft. Expect a summer slide to 9 to 31 ft, then a winter hold in 4 to 31 ft. Start at Break off the point. It's a drop-off holding about 8 ft of water and rates prime come summer. Prime time lands in after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 25 ft | dawn & dusk | Main-lake point (3 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Été | 9 to 31 ft | night & dawn | Break off the point (8 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Automne | 5 to 30 ft | dusk & dawn | Secondary point (10 ft) | Jerkbait over gravel, Casting spoon |
| Hiver | 4 to 31 ft | dawn | Break off the point (8 ft) | Jigging spoon, Small stickbait (slow) |
Come spring, look for walleye tight to the bank in 4 to 15 ft. Expect a summer slide to 9 to 31 ft, then a winter hold in 9 to 31 ft. Start at Deep basin. It's a deep basin holding about 22 ft of water and rates prime come winter. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Secondary point (10 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 9 to 31 ft | dusk & dawn | Break off the point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 9 to 31 ft | dusk & night | Break off the point (8 ft) | Jigging rap, Jig + big minnow |
| Hiver | 9 to 31 ft | dusk & dawn | Deep basin (22 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch 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 9 to 31 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 7 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (7 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 10 to 30 ft | dawn | Deep basin (22 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Automne | 9 to 31 ft | midday | Deep basin (22 ft) | Jigging spoon (small), Perch rig / spreader |
| Hiver | 9 to 31 ft | midday & dawn | Deep basin (22 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 7 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.

Start shallow in spring: smallmouth bass 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 9 to 31 ft. Top water on the chart: Secondary point, a point in the 10 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.

|---|---|---|---|---|
| Printemps | 3 to 12 ft | dawn & dusk | Main-lake point (3 ft) | Ned rig, Tube jig |
