44-acre lake in British Columbia. The lake tops out around 18 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 44 acres wrapped in 1.3 miles of bank. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. The shallow band under 15 ft claims about 94% of the surface on the model — that's where the groceries are. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. It sits in Cowichan Valley Regional District. Its nearest charted neighbour, Wild Deer Lake, is 2 mi to the southwest.
Spring puts brown trout in skinny water — 2 to 18 ft is the zone. Summer fish stay in 5 to 18 ft, and winter fish hold in 3 to 18 ft. Break off the point is the standout, a drop-off at roughly 8 ft, rated prime for summer brown trout. Plan around after dark and early morning in the warm months. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 5 to 18 ft | night & dawn | Break off the point (8 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 3 to 18 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 3 to 18 ft | dawn | Break off the point (8 ft) | Jigging spoon, Small stickbait (slow) |
When the water first warms, coho salmon slide up into 2 to 18 ft. There's no big seasonal slide here — summer means 5 to 18 ft, winter 5 to 18 ft. Start at Deep basin. It's a deep basin holding about 15 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a dodger + fly or a medium spoon above the thermocline rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 5 to 18 ft | dawn & dusk | Deep basin (15 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 4 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 5 to 18 ft | midday | Deep basin (15 ft) | Small spoon, slow troll |
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. Warm water sends them out to 5 to 18 ft; cold water stacks them in 5 to 18 ft. Break off the point is the standout, a drop-off at roughly 8 ft, rated prime for summer cutthroat trout. Plan around early morning and the evening in the warm months. A trolled spoon (small) or an inline spinner covers the summer program.
| 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 18 ft | dawn & dusk | Break off the point (8 ft) | Trolled spoon (small), Inline spinner |
| Fall | 4 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 5 to 18 ft | dawn | Break off the point (8 ft) | Small jigging spoon, Marabou jig |
Early season rainbow trout use the shallows, holding in 5 to 18 ft. Even in summer they hold at 5 to 18 ft; winter keeps them in 4 to 18 ft. Put Break off the point first on the milk run — a drop-off near 8 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 18 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 18 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 18 ft | dawn | Break off the point (8 ft) | Jigging spoon, Tube jig (white) |
