Rating depth structure for brook trout.

31-acre lake in Thunder Bay District, Ontario. The lake tops out around 74 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Box Lake draws 32 acres inside 1.6 miles of shoreline. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 41% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. The water lies in Thunder Bay District. Closest neighbour on DepthScout: Fishnet Lake, 1 mi northeast of here.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Break off the point, a drop-off in the 33 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (33 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (19 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
