364-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 31 ft. The depth chart comes from British Columbia Fish and Wildlife Branch bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 364 acres wrapped in 4.3 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. Roughly 44% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 1.7 mi with a 0.6-mi widest point. Bulkley-Nechako Regional District claims this one. Its nearest charted neighbour, Karena Lake, is 5 mi to the east.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 6 to 31 ft. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | open water | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | open water | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 31 ft chart-limited; documented 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 31 ft chart-limited; documented 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
