46-acre lake near Québec. The lake tops out around 10 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Lac Chahoun maps at 46 acres behind 1.1 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 0.4 mi, about 0.2 mi across. It sits in Maskinongé MRC. Lac Simpson sits 1 mi north — the closest neighbouring chart.

Spring brook trout on Lac Chahoun hold shallow, usually 1 to 10 ft. Depth-wise the year is flat: 3 to 10 ft in summer, 2 to 10 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 10 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.

Spring puts walleye in skinny water — 3 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 3 to 10 ft. Shoreline break is the standout, a drop-off at roughly 5 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. 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 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 3 to 10 ft covers winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and you'll meet the bite. 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. They move out to 3 to 10 ft in summer and finish the year down in 3 to 10 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

The spring pattern is a shallow one: rock bass in 2 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. Top water on the chart: Shoreline break, a drop-off in the 5 ft range, prime in fall. Time it for the evening. Summer baits: a ned rig (small) or a marabou jig gets it done.

The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. As the season builds they drop to 2 to 10 ft, wintering in 3 to 10 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for the evening and early morning. Summer baits: a micro tube or a sponge spider (fly) gets it done.

Lac Chahoun is about 10 ft (3 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 Chahoun atteint environ 3 m (10 pi) à son point le plus profond. Les profondeurs proviennent de relevés bathymétriques réels.
Anglers target brook trout, walleye, yellow perch, northern pike, rock bass, pumpkinseed on Lac Chahoun. 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.
Shoreline break is the top-rated area: a drop-off in about 5 ft of water that rates prime for walleye in fall. 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 Chahoun 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.
