2,694-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 75 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. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 2,620 acres wrapped in 23.7 miles of bank. That shoreline is heavily fingered (development index 3.3) — bays, points and pockets everywhere, which multiplies the fishable edge. About 32% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 7.1 mi end to end and 1.5 mi across at its widest. Bulkley-Nechako Regional District claims this one. Its nearest charted neighbour, Nechako Reservoir, is 4 mi to the west.
When the water first warms, kokanee slide up into 10 to 30 ft. Summer is a 30 to 70 ft game here, winter a 19 to 75 ft one. Start at Deep basin. It's a deep basin holding about 64 ft of water and rates prime come summer. The feeding windows run early morning. Keep a dodger + pink/orange squid on downrigger or a kokanee bug + corn rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Deep basin (64 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Deep basin (64 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Sharp break (5 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 19 to 75 ft | dawn | Deep basin (64 ft) | Small glow jig + corn or maggot, Tiny spoon |
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 23 to 75 ft game here, winter a 19 to 75 ft one. The chart's best answer is Deep basin — deep basin, 64 ft, prime for summer. Best bite is 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 | 10 to 40 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 23 to 75 ft | dawn | Deep basin (64 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (19 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 19 to 75 ft | dawn | Deep basin (64 ft) | White tube jig, Airplane jig |
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 8 to 40 ft. If you only fish one area, make it Sharp break: a drop-off around 5 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 | 5 to 20 ft | dawn & dusk | Main-lake point (19 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Sharp break (5 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Sharp break (5 ft) | Jigging spoon, Tube jig (white) |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. Warm water sends them out to 23 to 75 ft; cold water stacks them in 25 to 70 ft. Deep basin is the standout, a deep basin at roughly 64 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 | 15 to 45 ft | midday & dawn | Rock reef (3 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 23 to 75 ft | dawn | Deep basin (64 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (3 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (64 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
