1,341-acre lake near Québec. The lake tops out around 120 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 rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 1,341 acres, worked by 19.6 miles of shoreline. A development index of 3.8 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 21% of the surface — that's where the groceries are. End to end it runs roughly 7.7 mi, about 1.4 mi across. La Vallée-de-la-Gatineau MRC claims this one. Lac Kondiaronk sits 5 mi southwest — the closest neighbouring chart.

Spring brook trout on Lac Antostagan 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 Break off the point first on the milk run — a drop-off near 20 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 | 2 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | Main-lake point (9 ft) | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Break off the point (20 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 50 to 120 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 117 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 | Secondary point (26 ft) | Casting spoon over shoals, Jerkbait (shallow) |

| Hiver | 20 to 80 ft | dawn | Break off the point (20 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. Midsummer fish sit out in 40 to 90 ft before dropping to 25 to 70 ft for winter. The spot to know is Break off the point, a drop-off in about 20 ft of water that rates prime for lake whitefish in spring. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.

The spring pattern is a shallow one: cisco (lake herring) in 10 to 40 ft. Midsummer fish sit out in 40 to 80 ft before dropping to 20 to 60 ft for winter. The spot to know is Break off the point, a drop-off in about 20 ft of water that rates prime for cisco (lake herring) in winter. Plan around early morning in the warm months. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic 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 Break off the point, a prime-rated drop-off around 20 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 | 4 to 15 ft | dusk & dawn | Main-lake point (9 ft) | 1/8 oz jig + minnow, Hair jig |

In spring, sauger run shallow here, mostly 4 to 18 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 45 ft for winter. Fall sauger concentrate at Break off the point, a prime-rated drop-off around 20 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bottom bouncer + crawler or a 3-way rig with stickbait most summer days.
