Rating depth structure for rainbow trout.

20-acre lake in Comox Valley Regional District, British Columbia. The lake tops out around 47 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 20 acres, worked by 1.3 miles of shoreline, broken up by an island. With a 2.1 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 91% of the surface — that's where the groceries are. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. It sits in Comox Valley Regional District. If the bite dies, Kwai Lake is 0 mi to the northwest.
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Put Deep basin first on the milk run — a deep basin near 19 ft that grades prime for winter. In summer the feeding windows fall in 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 (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Deep basin (19 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Deep basin (19 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Deep basin (19 ft) | Jigging spoon, Tube jig (white) |
