13,578-acre lake in British Columbia. The lake tops out around 659 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. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Tetachuck Lake runs 13,548 acres with 71.3 miles of edge. An index of 4.4 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 7% of this chart, as modeled. Call it 22 mi long by 5.3 mi wide at the broadest reach. The water lies in Bulkley-Nechako Regional District. For a second option, Tschick Lake lies 13 mi southeast.
The spring pattern is a shallow one: kokanee in 10 to 30 ft. Midsummer fish sit out in 30 to 70 ft before dropping to 20 to 80 ft for winter. The spot to know is Offshore hump, an offshore hump in about 39 ft of water that rates prime for kokanee in summer. Plan around early morning in the warm months. Summer baits: a dodger + pink/orange squid on downrigger or a kokanee bug + corn gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Sharp break (17 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Offshore hump (39 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Sharp break (34 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Offshore hump (39 ft) | Small glow jig + corn or maggot, Tiny spoon |
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Sharp break, a drop-off in the 34 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shoreline point (16 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Sharp break (17 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Shoreline point (16 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Sharp break (34 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 13 features, led in depth by Deep basin at roughly 560 ft.
