254-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 56 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 254 acres of water rimmed by 4.8 miles of bank, with a single island in the mix. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. Roughly 71% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 1.2 mi with a 0.8-mi widest point. The water lies in Bulkley-Nechako Regional District. Closest neighbour on DepthScout: Wapoose Lake, 7 mi southwest of here.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. Spring rainbow trout concentrate at Main-lake point, a prime-rated point around 14 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (14 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (14 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (14 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Deep basin (48 ft) | Jigging spoon, Tube jig (white) |
5 pieces of structure are mapped here — Deep basin, around 48 ft, is the deepest of them.
