479-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 100 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Bluff Lake runs 479 acres with 4.7 miles of edge. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. 6% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 1.6 mi of water from one end to the other, 0.7 mi at the beam. You'll find it in Cariboo Regional District. For a second option, Sapeye Lake lies 3 mi north.
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Fall rainbow trout concentrate at Main-lake point, a prime-rated point around 25 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (25 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (25 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (45 ft) | Jigging spoon, Tube jig (white) |
Bluff Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 85 ft down.
