4,093-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 25 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Nulki Lake runs 3,987 acres with 15.4 miles of edge, broken up by an island. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 68% of this chart, as modeled. The basin spans about 4.8 mi end to end and 2.3 mi across at its widest. You'll find it in Bulkley-Nechako Regional District. Closest neighbour on DepthScout: Tachick Lake, 3 mi northwest of here.
In spring, kokanee run shallow here, mostly 8 to 25 ft. Summer keeps them at 8 to 25 ft, and they winter in 6 to 25 ft. Deep basin is the standout, a deep basin at roughly 21 ft, rated prime for spring kokanee. Time it for early morning. You won't need more than a dodger + pink/orange squid on downrigger or a kokanee bug + corn most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 25 ft | dawn | Deep basin (21 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 8 to 25 ft | dawn | Deep basin (21 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 3 to 25 ft | dawn | Creek inflow (4 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 6 to 25 ft | dawn | Deep basin (21 ft) | Small glow jig + corn or maggot, Tiny spoon |
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 7 to 25 ft, wintering in 5 to 25 ft. Spring rainbow trout concentrate at Creek inflow, a prime-rated inflow / creek mouth around 4 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Creek inflow (4 ft) | Inline spinner (silver), Small spoon |
| Summer | 7 to 25 ft | dawn & dusk | Old creek channel (13 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 25 ft | dawn & dusk | Gravel shoal (4 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 25 ft | dawn | Break off the point (11 ft) | Jigging spoon, Tube jig (white) |
Early season lake whitefish use the shallows, holding in 8 to 25 ft. Even in summer they hold at 8 to 25 ft; winter keeps them in 8 to 25 ft. The chart's best answer is Deep basin — deep basin, 21 ft, prime for summer. Best bite is early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 25 ft | midday & dawn | Break off the point (11 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 8 to 25 ft | dawn | Deep basin (21 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 7 to 25 ft | dusk | Gravel shoal (4 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 8 to 25 ft | midday & dawn | Deep basin (21 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
