9-acre lake in East Kootenay Regional District, British Columbia. The lake tops out around 32 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 9 acres wrapped in 0.5 miles of bank. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. About 43% 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. If the bite dies, Mcnair Lakes is 1 mi to the north.
When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 6 to 32 ft. If you only fish one area, make it Break off the point: a drop-off around 14 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (14 ft) | Dodger + spoon (deep troll), Flutter spoon |
