Rating depth structure for rainbow trout.

42-acre lake in British Columbia. The lake tops out around 69 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. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 42 acres, worked by 1.1 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. About 18% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 0.4 mi, about 0.2 mi across. It sits in Central Kootenay Regional District. Tanal Lake sits 1 mi northwest — the closest neighbouring chart.
The spring pattern is a shallow one: cutthroat trout in 3 to 15 ft. Midsummer fish sit out in 10 to 35 ft before dropping to 10 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 31 ft of water that rates prime for cutthroat trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a trolled spoon (small) or an inline spinner gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (17 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (31 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (17 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (31 ft) | Small jigging spoon, Marabou jig |
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 8 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 31 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 (17 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (31 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (17 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (31 ft) | Jigging spoon, Tube jig (white) |
