282-acre lake near Québec. The lake tops out around 187 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. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 282 acres wrapped in 3.4 miles of bank. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. About 12% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1.3 mi with a 0.7-mi widest point. It sits in Portneuf MRC. Its nearest charted neighbour, Lac Blanc, is 2 mi to the west.

When the water first warms, brook trout slide up into 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. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.

|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |

| Hiver | 3 to 20 ft | dawn | Shallow bay flat (9 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Put Secondary point first on the milk run — a point near 15 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.

Spring puts arctic char in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 20 to 60 ft, wintering in 10 to 40 ft. Spring arctic char concentrate at Shallow bay flat, a good-rated feeding flat around 9 ft. Warm-month bites cluster around early morning. A jigging spoon vertical or a tube jig (smelt) covers the summer program.

Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Fall lake whitefish concentrate at Main-lake point, a good-rated point around 8 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.

Spring cisco (lake herring) concentrate at Deep basin, a good-rated deep basin around 177 ft. Warm-month bites cluster around early morning. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.

Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Secondary point, a point in the 15 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.

Anglers target brook trout, lake trout, arctic char, lake whitefish, cisco (lake herring), walleye, yellow perch, northern pike, burbot on Lac Émeraude. 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.
Secondary point is the top-rated area: a point in about 15 ft of water that rates prime for walleye in fall. 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.
Fishing on Lac Émeraude is regulated by the Québec sport fishing rules (MELCCFP). Check the official Québec regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
