47-acre lake near Québec. The lake tops out around 18 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Lac O'Neil runs 47 acres with 1.3 miles of edge. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. Tip to tip the water measures near 0.6 mi with a 0.2-mi widest point. The water lies in La Nouvelle-Beauce MRC. The nearest mapped water is Lac Etchemin, 15 mi to the east.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 3 to 18 ft. Top water on the chart: Deep basin, a deep basin in the 14 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.

| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 5 to 18 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (14 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

The spring pattern is a shallow one: rainbow trout in 5 to 18 ft. The depth story barely changes: 5 to 18 ft through summer, 4 to 18 ft in winter. The spot to know is Break off the point, a drop-off in about 8 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.

Spring yellow perch on Lac O'Neil hold shallow, usually 3 to 12 ft. By summer they slide out to 5 to 18 ft, and by winter most fish are in 5 to 18 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 5 to 18 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.

Winter smallmouth bass 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 drop shot (goby/minnow) or a ned rig covers the summer program.

Lac O'Neil is about 18 ft (5 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Lac O'Neil atteint environ 5 m (18 pi) à son point le plus profond. Les profondeurs proviennent de relevés bathymétriques réels.
Anglers target brook trout, rainbow trout, yellow perch, northern pike, smallmouth bass, brown bullhead on Lac O'Neil. 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.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Every other rated spot, per species and season, is on the map above.
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.
