1,406-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 118 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 1,406 acres, worked by 14 miles of shoreline, broken up by an island. An index of 2.7 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 10% of this chart, as modeled. Call it 4.9 mi long by 0.9 mi wide at the broadest reach. Bulkley-Nechako Regional District claims this one. Wapoose Lake sits 5 mi northwest — the closest neighbouring chart.
When the water first warms, burbot slide up into 25 to 70 ft. Summer is a 35 to 118 ft game here, winter a 15 to 60 ft one. Start at Deep basin. It's a deep basin holding about 100 ft of water and rates prime come summer. The feeding windows run after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (53 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 35 to 118 ft | night & midday | Deep basin (100 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (53 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (53 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 35 to 118 ft game here, winter a 20 to 80 ft one. Start at Deep basin. It's a deep basin holding about 100 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (30 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 35 to 118 ft | dawn | Deep basin (100 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (30 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (53 ft) | White tube jig, Airplane jig |
Spring rainbow trout on Knapp Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. Put Main-lake point first on the milk run — a point near 30 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| 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 | Main-lake point (30 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (30 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (53 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Warm water sends them out to 40 to 90 ft; cold water stacks them in 25 to 70 ft. Top water on the chart: Break off the point, a drop-off in the 53 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (53 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Break off the point (53 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (30 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Break off the point (53 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
