89-acre lake in Nipissing District, Ontario. The lake tops out around 30 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. The depth data here comes from the Ontario MNRF survey of 1969, a decades-old survey (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Browns Lake runs 92 acres with 2.5 miles of edge. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 96% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.7 mi of water from one end to the other, 0.4 mi at the beam. You'll find it in Nipissing District. For a second option, Roko Lake lies 2 mi east.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 30 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| 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 |
The spring pattern is a shallow one: burbot in 9 to 30 ft. The depth story barely changes: 9 to 30 ft through summer, 8 to 30 ft in winter. The spot to know is Deep basin, a deep basin in about 30 ft of water that rates prime for burbot in spring. Plan around after dark and midday in the warm months. Summer baits: a heavy jig + cut bait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 30 ft | night & dusk | Deep basin (30 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |

| Fall | 9 to 30 ft | night & dusk | Deep basin (30 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 8 to 30 ft | night & dusk | Deep basin (30 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
