52-acre lake in Cowichan Valley Regional District, British Columbia. The lake tops out around 33 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 52 acres of water rimmed by 1.4 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. The shallow band under 15 ft claims about 64% of the surface — that's where the groceries are. Figure 0.5 mi of water from one end to the other, 0.3 mi at the beam. The water lies in Cowichan Valley Regional District. The nearest mapped water is Silver Lake, 1 mi to the northwest.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 7 to 33 ft. Top water on the chart: Break off the point, a drop-off in the 13 ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Secondary point (5 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (13 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 33 ft | dawn & dusk | Break off the point (13 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 33 ft | dawn | Break off the point (13 ft) | Jigging spoon, Tube jig (white) |
