4,488-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 126 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. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 4,368 acres, worked by 35.5 miles of shoreline — one island included. That shoreline is heavily fingered (development index 3.8) — bays, points and pockets everywhere, which multiplies the fishable edge. About 29% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 15.7 mi, about 1.5 mi across. It sits in Cariboo Regional District. Its nearest charted neighbour, Eagle Lake, is 5 mi to the south.
When the water first warms, kokanee slide up into 10 to 30 ft. By summer they slide out to 30 to 70 ft, and by winter most fish are in 20 to 80 ft. If you only fish one area, make it Sharp break: a drop-off around 11 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a dodger + pink/orange squid on downrigger or a kokanee bug + corn rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Sharp break (11 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Sharp break (38 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Sharp break (38 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Sharp break (38 ft) | Small glow jig + corn or maggot, Tiny spoon |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Fall lake whitefish concentrate at Rock reef, a prime-rated rock pile around 7 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Sharp break (38 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Sharp break (38 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (7 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Sharp break (38 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |

Tatla Lake is about 126 ft (38 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target kokanee, lake whitefish on Tatla Lake.
Rock reef is the top-rated area: a rock pile in about 7 ft of water that rates prime for lake whitefish in fall. Scroll up to the map for the complete spot list by species and season.
For kokanee, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
