3,608-acre lake near Lac-Brome. The lake tops out around 42 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 3,618 acres of water rimmed by 15.6 miles of bank. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 32% of this chart. Tip to tip the water measures near 4 mi with a 2.9-mi widest point. The water lies in Brome-Missisquoi MRC. For a second option, Lac Waterloo lies 6 mi north.

In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. Spring rainbow trout concentrate at Creek inflow, a prime-rated inflow / creek mouth around 4 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.

Anglers target rainbow trout, brown trout, walleye, yellow perch, northern pike, smallmouth bass, largemouth bass, rock bass, pumpkinseed, brown bullhead, common carp, chain pickerel on Lac Brome. 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.
Creek inflow is the top-rated area: an inflow / creek mouth in about 4 ft of water that rates prime for brown trout in spring. Scroll up to the map for the complete spot list by species and season.
For rainbow 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.
