8,748-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 313 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 8,749 acres of water rimmed by 42.9 miles of bank, with 5 islands in the mix. An index of 3.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 4% of this chart, as modeled. End to end it runs roughly 15.6 mi, about 2.1 mi across. You'll find it in Bulkley-Nechako Regional District. Closest neighbour on DepthScout: Abas Lake, 5 mi north of here.
Start shallow in spring: burbot sit in 25 to 70 ft that time of year. Warm water sends them out to 50 to 120 ft; cold water stacks them in 15 to 60 ft. Top water on the chart: Offshore hump, an offshore hump in the 23 ft range, prime in winter. 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 | Offshore hump (23 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Sharp break (75 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Sharp break (75 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Offshore hump (23 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 50 to 120 ft; cold water stacks them in 20 to 80 ft. Top water on the chart: Offshore hump, an offshore hump in the 23 ft range, prime in winter. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Offshore hump (23 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Sharp break (75 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Offshore hump (23 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Offshore hump (23 ft) | White tube jig, Airplane jig |
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: Shallow bay flat, a feeding flat in the 6 ft range, good in spring. 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 | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (141 ft) | Jigging spoon, Tube jig (white) |
When the water first warms, lake whitefish slide up into 15 to 45 ft. Summer is a 40 to 90 ft game here, winter a 25 to 70 ft one. Start at Offshore hump. It's an offshore hump holding about 23 ft of water and rates prime come winter. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Offshore hump (23 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Sharp break (75 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Offshore hump (23 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Offshore hump (23 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
