100-acre lake in British Columbia. The lake tops out around 35 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 100 acres of water rimmed by 3 miles of bank. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. About 69% 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 0.8 mi with a 0.6-mi widest point. You'll find it in Thompson-Nicola Regional District. Closest neighbour on DepthScout: Martha Lake, 1 mi east 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.

In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 7 to 35 ft. Break off the point is the standout, a drop-off at roughly 16 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 (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 35 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (16 ft) | Jigging spoon, Tube jig (white) |
6 pieces of structure are mapped here — Deep basin, around 30 ft, is the deepest of them.
