20-acre lake near Québec. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
The drawn water covers 20 acres wrapped in 0.7 miles of bank. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. 80% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.3 mi, about 0.2 mi across. Mékinac MRC claims this one. Its nearest charted neighbour, Lac de la Bécasse, is 1 mi to the northwest.

Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 6 to 20 ft game here, winter a 3 to 20 ft one. The chart's best answer is Deep basin — deep basin, 20 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 6 to 20 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Hiver | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring landlocked salmon on Lac du Héron hold shallow, usually 1 to 15 ft. They move out to 6 to 20 ft in summer and finish the year down in 5 to 20 ft. Put Deep basin first on the milk run — a deep basin near 20 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a dodger + streamer down deep or a thin spoon on lead core.

| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 1 to 15 ft | dawn & dusk | open water | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Été | 6 to 20 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Deep basin (20 ft) | Dodger + streamer down deep, Thin spoon on lead core |

| Hiver | 5 to 20 ft chart-limited; documented 10 to 40 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Swedish pimple + smelt |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. Deep basin is the standout, a deep basin at roughly 20 ft, rated prime for winter walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 6 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| 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 bay flat (6 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 |
| Hiver | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |

Lac du Héron is about 20 ft (6 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 du Héron atteint environ 6 m (20 pi) à son point le plus profond. Les profondeurs proviennent de relevés bathymétriques réels.
Anglers target brook trout, landlocked salmon, walleye, yellow perch, northern pike on Lac du Héron. 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 20 ft of water that rates prime for landlocked salmon in summer. Open the map above to see every rated 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.
