Rating depth structure for cutthroat trout.
Recent public catches load as you reach this section.
60-acre lake in British Columbia. The lake tops out around 230 ft. The surface is reconstructed from 88 measured spot soundings collected in 1981; water between those measurements is interpolated. Treat the contours between those soundings as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Shannon Lake draws 60 acres inside 1.4 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. Roughly 5% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.6 mi end to end and 0.2 mi across at its widest. You'll find it in Central Kootenay Regional District. For a second option, Wee Sandy Lake lies 5 mi south.
Come spring, look for cutthroat trout tight to the bank in 3 to 15 ft. Expect a summer slide to 10 to 35 ft, then a winter hold in 10 to 40 ft. Start at Main-lake point. It's a point holding about 1 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A trolled spoon (small) or an inline spinner is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Main-lake point (1 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Main-lake point (1 ft) | Small jigging spoon, Marabou jig |
Count 5 structure marks on this chart. The deepest, Deep basin, sits near 226 ft.
