67-acre lake in Squamish-Lillooet Regional District, British Columbia. The lake tops out around 121 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Species by species, here's what the data says the year looks like.
Drawn out, this is 67 acres of water rimmed by 1.6 miles of bank. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 26% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.6 mi long by 0.3 mi wide at the broadest reach. The water lies in Squamish-Lillooet Regional District. For a second option, Ogre Lake lies 4 mi southeast.
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 8 to 40 ft. Top water on the chart: Main-lake point, a point in the 30 ft range, prime in fall. 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 | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (30 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (30 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (54 ft) | Jigging spoon, Tube jig (white) |
