30-acre lake in East Kootenay Regional District, British Columbia. The lake tops out around 15 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. Species by species, here's what the data says the year looks like.
Drawn out, this is 30 acres of water rimmed by 1.1 miles of bank. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. The water lies in East Kootenay Regional District. The nearest mapped water is Surveyors Lake, 7 mi to the northeast.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. The depth story barely changes: 5 to 15 ft through summer, 2 to 15 ft in winter. The spot to know is Deep basin, a deep basin in about 13 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (13 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 15 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (13 ft) | Small jigging spoon, Tungsten jig + plastic |
