74-acre lake in Algoma District, Ontario. The lake tops out around 40 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
On the chart, Brown L. draws 74 acres inside 2.2 miles of shoreline. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 68% of this chart. Figure 0.8 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Algoma District. The nearest mapped water is Lefebvre Lake 22, 2 mi to the south.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 30 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (10 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts splake in skinny water — 5 to 25 ft is the zone. As the season builds they drop to 12 to 40 ft, wintering in 9 to 40 ft. Summer splake concentrate at Break off the point, a prime-rated drop-off around 10 ft. Warm-month bites cluster around early morning and the evening. A trolled spoon at the thermocline or a white tube jig (deep) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Break off the point (10 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 12 to 40 ft | dawn & dusk | Break off the point (10 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (10 ft) | Casting spoon, Jerkbait |
| Winter | 9 to 40 ft | dawn | Break off the point (10 ft) | Jigging spoon tipped with minnow head, Small white tube |
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Deep basin: a deep basin around 30 ft that scores prime in fall. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (30 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 30 ft.
