785-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 73 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Tyhee Lake draws 903 acres inside 6.7 miles of shoreline. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. The shallow band under 15 ft claims about 9% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 2.7 mi with a 0.9-mi widest point. You'll find it in Bulkley-Nechako Regional District. Closest neighbour on DepthScout: Mcdowell Lake, 4 mi northeast of here.
Spring puts burbot in skinny water — 25 to 70 ft is the zone. Warm water sends them out to 22 to 73 ft; cold water stacks them in 15 to 60 ft. Deep basin is the standout, a deep basin at roughly 62 ft, rated prime for spring burbot. Plan around after dark and midday in the warm months. A heavy jig + cut bait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (62 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 22 to 73 ft | night & midday | Deep basin (62 ft) | Heavy jig + cut bait |
| Fall | 22 to 73 ft | night & dusk | Deep basin (62 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (62 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Come spring, look for cutthroat trout tight to the bank in 3 to 15 ft. Expect a summer slide to 10 to 35 ft, then a winter hold in 10 to 40 ft. Start at Break off the point. It's a drop-off holding about 33 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A trolled spoon (small) or an inline spinner is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (18 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (33 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (33 ft) | Small jigging spoon, Marabou jig |
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 33 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 | Main-lake point (18 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (33 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (33 ft) | Jigging spoon, Tube jig (white) |
Early season lake whitefish use the shallows, holding in 15 to 45 ft. Summer is a 22 to 73 ft game here, winter a 25 to 70 ft one. The chart's best answer is Deep basin — deep basin, 62 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 | 15 to 45 ft | midday & dawn | Break off the point (33 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 22 to 73 ft | dawn | Deep basin (62 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (18 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (62 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
