3,459-acre lake near Saint-Donat. The lake tops out around 129 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.
The drawn water covers 3,356 acres wrapped in 28.6 miles of bank, broken up by 2 islands. An index of 3.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 27% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 6.9 mi, about 2.2 mi across. It sits in Matawinie MRC. Lac Beauchamp sits 2 mi east — the closest neighbouring chart.

Spring brook trout on Lac Archambault 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 Creek inflow — inflow / creek mouth, 2 ft, prime for spring. 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 | Creek inflow (2 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Creek inflow (2 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Creek inflow (2 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Creek inflow (2 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Start at Deepest basin. It's a deep basin holding about 126 ft of water and rates prime come summer. Prime time lands in 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 | Secondary point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Été | 50 to 120 ft | dawn | Deepest basin (126 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Automne | 10 to 50 ft | dusk & dawn | Rock reef (5 ft) | Heavy casting spoon, Jigging rap over reefs |
| Hiver | 20 to 80 ft | dawn | Rock reef (5 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: arctic char in 4 to 15 ft. As the season builds they drop to 20 to 60 ft, wintering in 10 to 40 ft. Top water on the chart: Rock reef, a rock pile in the 5 ft range, prime in fall. Time it for early morning. Summer baits: a jigging spoon vertical or a tube jig (smelt) gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | midday & dawn | Rock reef (5 ft) | Small casting spoon (silver/orange), Jerkbait (small) |
| Été | 20 to 60 ft | dawn | Deep basin (127 ft) | Jigging spoon vertical, Tube jig (smelt) |
| Automne | 8 to 30 ft | midday & dusk | Rock reef (5 ft) | Casting spoon (orange/gold), Beadhead streamer |
| Hiver | 10 to 40 ft | midday & dawn | Deep basin (127 ft) | Jigging spoon (glow/silver), Tungsten jig + plastic |
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Top water on the chart: Rock reef, a rock pile in the 5 ft range, prime in fall. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 15 to 45 ft | midday & dawn | Shallow feeding flat (35 ft) | Small jig + waxworm, Blade bait (small) |
| Été | 40 to 90 ft | dawn | Shallow feeding flat (35 ft) | Blade bait vertical, Small jigging spoon |
| Automne | 8 to 30 ft | dusk | Rock reef (5 ft) | Small spoon (gold), Jig + plastic larva |
| Hiver | 25 to 70 ft | midday & dawn | Shallow feeding flat (35 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
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 20 to 40 ft. Rock reef is the standout, a rock pile at roughly 5 ft, rated prime for spring 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 | Rock reef (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 15 to 35 ft | dusk & dawn | Old creek channel (14 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 12 to 40 ft | dusk & night | Secondary point (10 ft) | Jigging rap, Jig + big minnow |
| Hiver | 20 to 40 ft | dusk & dawn | Old creek channel (14 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: Back-bay flat, a weed flat in the 6 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 | Back-bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |

| Automne | 12 to 35 ft | midday | Deep basin (127 ft) | Jigging spoon (small), Perch rig / spreader |
| Hiver | 15 to 35 ft | midday & dawn | Shallow feeding flat (35 ft) | Tungsten jig + spikes, Rattle spoon (small) |

Anglers target brook trout, lake trout, arctic char, lake whitefish, walleye, yellow perch, northern pike, smallmouth bass, rock bass, pumpkinseed, brown bullhead, channel catfish, burbot on Lac Archambault. This species list is an informed estimate from Québec's provincial fish-range maps (bounded by each lake's depth and habitat), not a per-lake fish survey — Québec doesn't publish per-lake species records.
Creek inflow is the top-rated area: an inflow / creek mouth in about 2 ft of water that rates prime for brook trout in spring. Scroll up to the map for the complete spot list by 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.
