36-acre lake in Alberni-Clayoquot Regional District, British Columbia. The lake tops out around 36 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
The drawn water covers 36 acres wrapped in 1.4 miles of bank. A middling shoreline index (1.7) gives it some bays to work without being a maze. 58% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.6 mi, about 0.2 mi across. It sits in Alberni-Clayoquot Regional District. Its nearest charted neighbour, Pachena Lake, is 2 mi to the west.
Start shallow in spring: cutthroat trout sit in 3 to 15 ft that time of year. Warm water sends them out to 10 to 35 ft; cold water stacks them in 9 to 36 ft. Top water on the chart: Break off the point, a drop-off in the 30 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (3 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (30 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Secondary point (4 ft) | Casting spoon, Inline spinner |
| Winter | 9 to 36 ft | dawn | Break off the point (30 ft) | Small jigging spoon, Marabou jig |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 7 to 36 ft. Start at Break off the point. It's a drop-off holding about 30 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Secondary point (4 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (30 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (30 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 36 ft | dawn | Break off the point (30 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 33 ft.
