9,670-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 499 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 9,678 acres wrapped in 34.2 miles of bank. An index of 2.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 12% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 14.3 mi with a 2.2-mi widest point. Cariboo Regional District claims this one. If the bite dies, Tsuniah Lake is 14 mi to the east.
Spring rainbow trout on Tatlayoko Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. Put Shoreline point first on the milk run — a point near 24 ft that grades prime for fall. The feeding windows run 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 | 5 to 20 ft | dawn & dusk | Rock reef (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Rock reef (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Shoreline point (24 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Rock reef (6 ft) | Jigging spoon, Tube jig (white) |
12 pieces of structure are mapped here — Deep basin, around 424 ft, is the deepest of them.
