Rating depth structure for cutthroat trout.
Recent public catches load as you reach this section.
12-acre lake in British Columbia. The lake tops out around 13 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 12 acres, worked by 0.6 miles of shoreline. Nearly circular (index 1.3), 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. Tip to tip the water measures near 0.3 mi. It sits in Central Kootenay Regional District. Kaslo Lake sits 1 mi southeast — the closest neighbouring chart.
Start shallow in spring: cutthroat trout sit in 3 to 13 ft that time of year. They don't go far with the seasons — 4 to 13 ft covers summer, 3 to 13 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 6 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a trolled spoon (small) or an inline spinner until the fish tell you otherwise.
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 | 3 to 13 ft chart-limited; documented 3 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 4 to 13 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Break off the point (6 ft) | Trolled spoon (small), Inline spinner |
| Fall | 3 to 13 ft chart-limited; documented 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 3 to 13 ft chart-limited; documented 10 to 40 ft | dawn | Break off the point (6 ft) | Small jigging spoon, Marabou jig |
