242-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 23 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
Tanglechain Lake maps at 242 acres behind 3.4 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. About 77% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 1 mi end to end and 0.7 mi across at its widest. Bulkley-Nechako Regional District claims this one. Its nearest charted neighbour, Doris Lake, is 1 mi to the northwest.
Come spring, look for burbot tight to the bank in 7 to 23 ft. Through summer count on 7 to 23 ft; the winter hold is 6 to 23 ft. If you only fish one area, make it Deep basin: a deep basin around 20 ft that scores prime in spring. Best bite is after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 23 ft | night & dusk | Deep basin (20 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 7 to 23 ft | night & midday | Deep basin (20 ft) | Heavy jig + cut bait |
| Fall | 7 to 23 ft | night & dusk | Deep basin (20 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 6 to 23 ft | night & dusk | Deep basin (20 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. As the season builds they drop to 7 to 23 ft, wintering in 6 to 23 ft. Summer cutthroat trout concentrate at Break off the point, a prime-rated drop-off around 10 ft. Warm-month bites cluster around early morning and the evening. A trolled spoon (small) or an inline spinner covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 7 to 23 ft | dawn & dusk | Break off the point (10 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 23 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 6 to 23 ft | dawn | Break off the point (10 ft) | Small jigging spoon, Marabou jig |
Come spring, look for lake trout tight to the bank in 6 to 23 ft. Through summer count on 7 to 23 ft; the winter hold is 6 to 23 ft. If you only fish one area, make it Deep basin: a deep basin around 20 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 23 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 7 to 23 ft | dawn | Deep basin (20 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 5 to 23 ft | dusk & dawn | Main-lake point (8 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 6 to 23 ft | dawn | Deep basin (20 ft) | White tube jig, Airplane jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is a 6 to 23 ft game here, winter a 5 to 23 ft one. The chart's best answer is Break off the point — drop-off, 10 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 6 to 23 ft | dawn & dusk | Break off the point (10 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 23 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 23 ft | dawn | Break off the point (10 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: lake whitefish in 7 to 23 ft. The depth story barely changes: 7 to 23 ft through summer, 7 to 23 ft in winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 23 ft | midday & dawn | Break off the point (10 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 7 to 23 ft | dawn | Deep basin (20 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 6 to 23 ft | dusk | Break off the point (10 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 7 to 23 ft | midday & dawn | Deep basin (20 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
