Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
9-acre lake in Cowichan Valley Regional District, British Columbia. The lake tops out around 19 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. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 9 acres of water rimmed by 0.5 miles of bank. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. The shallow band under 15 ft claims about 84% of the surface on the model — that's where the groceries are. The water lies in Cowichan Valley Regional District. The nearest mapped water is Cowichan Lake, 5 mi to the southwest.
Early season cutthroat trout use the shallows, holding in 3 to 15 ft. Summer is a 5 to 19 ft game here, winter a 5 to 19 ft one. The chart's best answer is Break off the point — drop-off, 9 ft, prime for summer. Best bite is early morning and the evening. Tie on a trolled spoon (small) or an inline spinner and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 5 to 19 ft | dawn & dusk | Break off the point (9 ft) | Trolled spoon (small), Inline spinner |
| Fall | 4 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 5 to 19 ft | dawn | Break off the point (9 ft) | Small jigging spoon, Marabou jig |
The spring pattern is a shallow one: rainbow trout in 5 to 19 ft. The depth story barely changes: 5 to 19 ft through summer, 4 to 19 ft in winter. The spot to know is Break off the point, a drop-off in about 9 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 19 ft | dawn & dusk | Break off the point (9 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 19 ft | dawn | Break off the point (9 ft) | Jigging spoon, Tube jig (white) |
