Rating depth structure for rainbow trout.

41-acre lake in Columbia-Shuswap Regional District, British Columbia. The lake tops out around 39 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 41 acres, worked by 1.2 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 52% of this chart, as modeled. Tip to tip the water measures near 0.5 mi with a 0.2-mi widest point. Columbia-Shuswap Regional District claims this one. If the bite dies, Gavia Lakes is 1 mi to the southwest.
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 39 ft one. The chart's best answer is Break off the point — drop-off, 18 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (10 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (18 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 39 ft | dawn | Break off the point (18 ft) | Jigging spoon, Tube jig (white) |
5 pieces of structure are mapped here — Deep basin, around 33 ft, is the deepest of them.
