10-acre lake near Québec. The lake tops out around 15 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.
The drawn water covers 10 acres wrapped in 0.5 miles of bank. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. Portneuf MRC claims this one. Lac Tessier sits 0 mi north — the closest neighbouring chart.

Spring brook trout on Lac Proulx hold shallow, usually 2 to 15 ft. Depth-wise the year is flat: 5 to 15 ft in summer, 2 to 15 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 15 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.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (15 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Automne | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |

Spring puts walleye in skinny water — 4 to 15 ft is the zone. Summer fish stay in 5 to 15 ft, and winter fish hold in 5 to 15 ft. Winter walleye concentrate at Deep basin, a prime-rated deep basin around 15 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.

Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 5 to 15 ft, and winter fish settle into 5 to 15 ft. The spot to know is Shallow bay flat, a weed flat in about 4 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 northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 5 to 15 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

Lac Proulx is about 15 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 Proulx atteint environ 5 m (15 pi) à son point le plus profond. Les profondeurs proviennent de relevés bathymétriques réels.
Anglers target brook trout, walleye, yellow perch, northern pike on Lac Proulx. 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 15 ft of water that rates prime for walleye in winter. 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.
Fishing on Lac Proulx 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.
