1,375-acre lake in Squamish-Lillooet Regional District, British Columbia. The lake tops out around 390 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here's the year, species by species, as the scoring engine sees it.
Cheakamus Lake maps at 1,375 acres behind 9 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. About 0% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 3.7 mi with a 1-mi widest point. It sits in Squamish-Lillooet Regional District. Its nearest charted neighbour, Alpha Lake, is 7 mi to the northwest.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Start at Shallow bay flat. It's a feeding flat holding about 6 ft of water and rates good come spring. 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 | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (176 ft) | Jigging spoon, Tube jig (white) |
