197-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 16 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Species by species, here's what the data says the year looks like.
The drawn water covers 197 acres wrapped in 4.1 miles of bank. With a 2.1 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 92% of this chart, as modeled. End to end it runs roughly 1.8 mi, about 0.3 mi across. It sits in Cariboo Regional District. If the bite dies, Tanya Lakes is 2 mi to the southwest.
Spring rainbow trout on Tanya Lakes hold shallow, usually 4 to 16 ft. Depth-wise the year is flat: 4 to 16 ft in summer, 3 to 16 ft once it turns cold. The chart's best answer is Break off the point — drop-off, 7 ft, prime for winter. Prime time lands in 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 | 4 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 16 ft | dawn & dusk | Break off the point (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 16 ft | dawn | Break off the point (7 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: lake whitefish sit in 5 to 16 ft that time of year. They don't go far with the seasons — 5 to 16 ft covers summer, 5 to 16 ft covers winter. The spot to know is Deep basin, a deep basin in about 14 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. 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 | 5 to 16 ft | midday & dawn | Break off the point (7 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 5 to 16 ft | dawn | Deep basin (14 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 4 to 16 ft | dusk | Break off the point (7 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 5 to 16 ft | midday & dawn | Deep basin (14 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 14 ft.
