92-acre lake in Kenora District, Ontario. The lake tops out around 16 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
Lacourse Lake maps at 92 acres behind 3.5 miles of shoreline — one island included. That shoreline is heavily fingered (development index 2.6) — bays, points and pockets everywhere, which multiplies the fishable edge. About 97% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.8 mi end to end and 0.5 mi across at its widest. Kenora District claims this one. Peterson Lake sits 1 mi northwest — the closest neighbouring chart.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 5 to 16 ft, and winter fish settle into 5 to 16 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 16 ft | dawn | Deep basin (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft | midday | Deep basin (16 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16 ft | midday & dawn | Deep basin (16 ft) | Tungsten jig + spikes, Rattle spoon (small) |
