2,005-acre lake in British Columbia. The lake tops out around 24 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 the data behind the map says about each species, season by season:
On the chart, Ahbau Lake draws 2,000 acres inside 14.3 miles of shoreline. A development index of 2.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. 80% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 5.3 mi with a 1-mi widest point. You'll find it in Cariboo Regional District. Closest neighbour on DepthScout: Hay Lake, 6 mi north of here.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.
Official exact-water fish record. The listing documents source-recorded presence, not present abundance or guaranteed catchability.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 6 to 24 ft, and winter fish settle into 5 to 24 ft. Break off the point is the standout, a drop-off at roughly 11 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 6 to 24 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (11 ft) | Dodger + spoon (deep troll), Flutter spoon |
