71-acre lake in Squamish-Lillooet Regional District, British Columbia. The lake tops out around 122 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 71 acres of water rimmed by 2.1 miles of bank — one island included. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 38% of this chart. Call it 0.6 mi long by 0.3 mi wide at the broadest reach. You'll find it in Squamish-Lillooet Regional District. Closest neighbour on DepthScout: Ogre Lake, 2 mi southwest of here.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. The spot to know is Main-lake point, a point in about 7 ft of water that rates prime for rainbow trout in spring. Warm-month bites cluster around early morning and the evening. 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 | Main-lake point (7 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (7 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (49 ft) | Jigging spoon, Tube jig (white) |
