861-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 16 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 861 acres, worked by 6.9 miles of shoreline — 2 islands included. A middling shoreline index (1.7) gives it some bays to work without being a maze. 92% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 2.6 mi long by 0.9 mi wide at the broadest reach. Bulkley-Nechako Regional District claims this one. Nulki Lake sits 7 mi west — the closest neighbouring chart.
Come spring, look for rainbow trout tight to the bank in 4 to 16 ft. Through summer count on 4 to 16 ft; the winter hold is 3 to 16 ft. If you only fish one area, make it Break off the point: a drop-off around 7 ft that scores prime in winter. Best bite is 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 | 4 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 16 ft | dawn & dusk | Break off the point (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 16 ft | dawn | Break off the point (7 ft) | Jigging spoon, Tube jig (white) |
Spring puts lake whitefish in skinny water — 5 to 16 ft is the zone. Summer fish stay in 5 to 16 ft, and winter fish hold in 5 to 16 ft. Deep basin is the standout, a deep basin at roughly 14 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 16 ft | midday & dawn | Break off the point (7 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 5 to 16 ft | dawn | Deep basin (14 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 4 to 16 ft | dusk | Break off the point (7 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 5 to 16 ft | midday & dawn | Deep basin (14 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
