18-acre lake in Central Kootenay Regional District, British Columbia. The lake tops out around 11 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Larson Lake draws 18 acres inside 0.8 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. The water lies in Central Kootenay Regional District. Closest neighbour on DepthScout: Cameron Lake, 3 mi northeast of here.
Spring puts brook trout in skinny water — 1 to 11 ft is the zone. Summer fish stay in 3 to 11 ft, and winter fish hold in 2 to 11 ft. Deep basin is the standout, a deep basin at roughly 9 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 | 1 to 11 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 3 to 11 ft | dawn & dusk | Deep basin (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 11 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 11 ft | dawn | Deep basin (9 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, rainbow trout run shallow here, mostly 3 to 11 ft. Summer keeps them at 3 to 11 ft, and they winter in 2 to 11 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 5 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 11 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
