342-acre lake near Québec. The lake tops out around 40 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 the data behind the map says about each species, season by season:
Drawn out, this is 342 acres of water rimmed by 5.8 miles of bank. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Roughly 58% of the water is 15 ft or less, the band where the food chain lives. Call it 1.7 mi long by 1.2 mi wide at the broadest reach. You'll find it in La Vallée-de-la-Gatineau MRC. The nearest mapped water is Lac du Portage, 3 mi to the east.

Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Spring brook trout concentrate at Main-lake point, a prime-rated point around 10 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (10 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (5 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (5 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. If you only fish one area, make it Deep basin: a deep basin around 40 ft that scores prime in winter. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Main-lake point (10 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 15 to 35 ft | dusk & dawn | Shallow feeding flat (19 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 12 to 40 ft | dusk & night | Main-lake point (10 ft) | Jigging rap, Jig + big minnow |
| Hiver | 20 to 40 ft | dusk & dawn | Deep basin (40 ft) | Jigging spoon + minnow head, Rattle bait |
Early season sauger use the shallows, holding in 4 to 18 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 12 to 40 ft. Put Deep basin first on the milk run — a deep basin near 40 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a bottom bouncer + crawler or a 3-way rig with stickbait and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 18 ft | dawn & dusk | Main-lake point (10 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (5 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |
| Automne | 12 to 35 ft | dusk & dawn | Break off the point (5 ft) | Jig + big minnow, Blade bait |
| Hiver | 12 to 40 ft | dusk | Deep basin (40 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 10 to 30 ft | dawn | Shallow feeding flat (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Automne | 12 to 35 ft | midday | Deep basin (40 ft) | Jigging spoon (small), Perch rig / spreader |
| Hiver | 15 to 35 ft | midday & dawn | Deep basin (40 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Été | 8 to 20 ft | dawn & dusk | Shallow feeding flat (19 ft) | Bucktail, Weedless spoon over cabbage |
| Automne | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |

Anglers target brook trout, walleye, sauger, yellow perch, northern pike on Lac au Barrage. 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.
Deep basin is the top-rated area: a deep basin in about 40 ft of water that rates prime for walleye in winter. 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.
