372-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 89 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 372 acres of water rimmed by 7.3 miles of bank, with 2 islands in the mix. A development index of 2.7 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 16% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 2.6 mi with a 0.5-mi widest point. You'll find it in Bulkley-Nechako Regional District. For a second option, Klawli Lake lies 5 mi south.
Start shallow in spring: burbot sit in 25 to 70 ft that time of year. Warm water sends them out to 27 to 89 ft; cold water stacks them in 15 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 76 ft range, prime in summer. Fish it in after dark and midday and you'll meet the bite. Throw a heavy jig + cut bait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (76 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 27 to 89 ft | night & midday | Deep basin (76 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (76 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (40 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 40 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (22 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (22 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (22 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (40 ft) | Jigging spoon, Tube jig (white) |
