226-acre lake near Québec. The lake tops out around 53 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. Species by species, here's what the data says the year looks like.
Lac O'Neil maps at 226 acres behind 2.9 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 12% of the surface — that's where the groceries are. Call it 1.3 mi long by 0.4 mi wide at the broadest reach. Antoine-Labelle MRC claims this one. Its nearest charted neighbour, Lac Bigelow, is 4 mi to the west.

Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Main-lake point — point, 15 ft, prime for spring. 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.

It's a deep basin holding about 53 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.

The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
