155-acre lake in Nipissing District, Ontario. The lake tops out around 46 ft. The depth data here comes from the Ontario MNRF survey of 1990 (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
Brown Lake maps at 155 acres behind 3.8 miles of shoreline. A development index of 2.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 61% of the water is 15 ft or less, the band where the food chain lives. Figure 1.1 mi of water from one end to the other, 0.5 mi at the beam. It sits in Nipissing District. Its nearest charted neighbour, Falcon Lake, is 1 mi to the northeast.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 20 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.

|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Back-bay flat is the standout, a weed flat at roughly 9 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|

A micro tube or a sponge spider (fly) covers the summer program.

|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (2 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (2 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (9 ft) | Micro jig + waxworm, Small spoon tipped |
