Fishing Tetachuck Lake: what the data says
13,578-acre lake in British Columbia. The lake tops out around 659 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. 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. A development index of 4.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. 7% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
Kokanee fishing at Tetachuck Lake
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, a 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 |
Rainbow Trout fishing at Tetachuck Lake
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.

|---|---|---|---|---|
