Rating depth structure for cutthroat trout.
Recent public catches load as you reach this section.
4-acre lake in British Columbia. The lake tops out around 56 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 4 acres, worked by 0.3 miles of shoreline. Nearly circular (index 1.2), so the story is the bottom, not the bank. About 16% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. It sits in East Kootenay Regional District. Wall Lake sits 3 mi east — the closest neighbouring chart.
In spring, cutthroat trout run shallow here, mostly 3 to 15 ft. Midsummer fish sit out in 10 to 35 ft before dropping to 10 to 40 ft for winter. Summer cutthroat trout concentrate at Shoreline break, a prime-rated drop-off around 25 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a trolled spoon (small) or an inline spinner most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Shoreline break (25 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Shoreline break (25 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Shoreline break (25 ft) | Small jigging spoon, Marabou jig |
