37-acre lake in Capital Regional District, British Columbia. The lake tops out around 25 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. Species by species, here's what the data says the year looks like.
The drawn water covers 37 acres wrapped in 1.7 miles of bank. With a 2 development index there's bank structure worth casting at, in moderation. About 79% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.4 mi end to end and 0.3 mi across at its widest. Capital Regional District claims this one. If the bite dies, Crabapple Lake is 1 mi to the north.
In spring, cutthroat trout run shallow here, mostly 3 to 15 ft. Summer pushes them deeper, 7 to 25 ft, and winter fish settle into 6 to 25 ft. Break off the point is the standout, a drop-off at roughly 11 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 | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 7 to 25 ft | dawn & dusk | Break off the point (11 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
