2,441-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 80 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
Drawn out, this is 2,315 acres of water rimmed by 24.3 miles of bank, with 3 islands in the mix. With a shoreline index of 3.6, this water is all arms and coves — edge habitat well beyond its acreage. 14% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 6 mi with a 2.8-mi widest point. The water lies in Cariboo Regional District. The nearest mapped water is Kappan Lake, 11 mi to the west.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. The spot to know is Dean River inflow, an inflow / creek mouth in about 8 ft of water that rates prime for rainbow trout in spring. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Dean River inflow (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Dean River inflow (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (20 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (36 ft) | Jigging spoon, Tube jig (white) |
