147-acre lake in Alberni-Clayoquot Regional District, British Columbia. The lake tops out around 108 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. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 147 acres wrapped in 3.1 miles of bank — one island included. With a 1.8 development index there's bank structure worth casting at, in moderation. Roughly 16% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 1.2 mi end to end and 0.3 mi across at its widest. Alberni-Clayoquot Regional District claims this one. If the bite dies, Turnbull Lake is 1 mi to the north.
In spring, cutthroat trout run shallow here, mostly 3 to 15 ft. Summer pushes them deeper, 10 to 35 ft, and winter fish settle into 10 to 40 ft. Main-lake point is the standout, a point at roughly 27 ft, rated prime for summer cutthroat trout. Time it for early morning and the evening. You won't need more than a trolled spoon (small) or an inline spinner most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Main-lake point (27 ft) | Trolled spoon (small), Inline spinner |

Spring rainbow trout on Ash Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. Put Main-lake point first on the milk run — a point near 27 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (27 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (27 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (49 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 92 ft.
