57-acre lake in Squamish-Lillooet Regional District, British Columbia. The lake tops out around 24 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What the data behind the map says about each species, season by season:
Gwyneth Lake maps at 57 acres behind 1.7 miles of shoreline, broken up by an island. A middling shoreline index (1.6) gives it some bays to work without being a maze. Roughly 85% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.7 mi end to end and 0.2 mi across at its widest. It sits in Squamish-Lillooet Regional District. Mead Lake sits 3 mi east — the closest neighbouring chart.
Start shallow in spring: cutthroat trout sit in 3 to 15 ft that time of year. Warm water sends them out to 7 to 24 ft; cold water stacks them in 6 to 24 ft. Top water on the chart: Break off the point, a drop-off in the 11 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a trolled spoon (small) or an inline spinner until the fish tell you otherwise.
| 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 | 7 to 24 ft | dawn & dusk | Break off the point (11 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 24 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 6 to 24 ft | dawn | Break off the point (11 ft) | Small jigging spoon, Marabou jig |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 6 to 24 ft, then a winter hold in 5 to 24 ft. Start at Break off the point. It's a drop-off holding about 11 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 6 to 24 ft | dawn & dusk | Break off the point (11 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 24 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 24 ft | dawn | Break off the point (11 ft) | Jigging spoon, Tube jig (white) |
