144-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 32 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 144 acres, worked by 2.9 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 67% of this chart, as modeled. Call it 0.9 mi long by 0.5 mi wide at the broadest reach. It sits in Bulkley-Nechako Regional District. Whitefish Lake sits 2 mi north — the closest neighbouring chart.
Early season lake trout use the shallows, holding in 8 to 32 ft. Even in summer they hold at 10 to 32 ft; winter keeps them in 8 to 32 ft. Put Deep basin first on the milk run — a deep basin near 27 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 32 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 10 to 32 ft | dawn | Deep basin (27 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 6 to 32 ft | dusk & dawn | Main-lake point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 8 to 32 ft | dawn | Deep basin (27 ft) | White tube jig, Airplane 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 6 to 32 ft. Start at Break off the point. It's a drop-off holding about 14 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 | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (14 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 32 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 32 ft | dawn | Break off the point (14 ft) | Jigging spoon, Tube jig (white) |
