131-acre lake in British Columbia. The lake tops out around 22 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. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Napier Lake draws 131 acres inside 4.6 miles of shoreline. A development index of 2.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. 88% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 2 mi long by 0.3 mi wide at the broadest reach. The water lies in Thompson-Nicola Regional District. For a second option, Fraser Lake lies 4 mi south.
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.

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 6 to 22 ft; cold water stacks them in 4 to 22 ft. Break off the point is the standout, a drop-off at roughly 10 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
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 22 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (10 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 22 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 22 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (10 ft) | Jigging spoon, Tube jig (white) |

Break off the point is the top-rated area: a drop-off in about 10 ft of water that rates prime for rainbow trout in winter. Every other rated spot, per species and season, is on the map above.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
