86-acre lake near Québec. The lake tops out around 7 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Lac Dion maps at 86 acres behind 1.6 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 0.7 mi with a 0.3-mi widest point. Bellechasse MRC claims this one. If the bite dies, Lac Vert is 3 mi to the northwest.

Spring brook trout on Lac Dion hold shallow, usually 1 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 1 to 7 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 7 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.

|---|---|---|---|---|
| Printemps | 1 to 7 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |

Early season rainbow trout use the shallows, holding in 2 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 1 to 7 ft. The chart's best answer is Break off the point — drop-off, 7 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.

Start shallow in spring: yellow perch sit in 2 to 7 ft that time of year. They don't go far with the seasons — 2 to 7 ft covers summer, 2 to 7 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.

Come spring, look for smallmouth bass tight to the bank in 2 to 7 ft. Through summer count on 2 to 7 ft; the winter hold is 2 to 7 ft. Start at Main-lake point. It's a point holding about 2 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.

When the water first warms, brown bullhead slide up into 2 to 7 ft. There's no big seasonal slide here — summer means 2 to 7 ft, winter 2 to 7 ft. Start at Deep basin. It's a deep basin holding about 7 ft of water and rates prime come winter. The feeding windows run after dark and the evening.

Lac Dion is about 7 ft (2 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 Dion atteint environ 2 m (7 pi) à son point le plus profond. Les profondeurs proviennent de relevés bathymétriques réels.
Anglers target brook trout, rainbow trout, yellow perch, smallmouth bass, brown bullhead on Lac Dion. 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 2 ft of water that rates prime for yellow perch in spring. The interactive chart above rates every spot for each 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 Dion 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.
