236-acre lake in Squamish-Lillooet Regional District, British Columbia. The lake tops out around 79 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Tyaughton Lake runs 236 acres with 5 miles of edge. A development index of 2.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. 20% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 2 mi, about 0.6 mi across. The water lies in Squamish-Lillooet Regional District. For a second option, Pearson Pond lies 2 mi south.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. The spot to know is Break off the point, a drop-off in about 36 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (20 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (20 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (20 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (36 ft) | Jigging spoon, Tube jig (white) |
