Rating depth structure for rainbow trout.

1,375-acre lake in Squamish-Lillooet Regional District, British Columbia. The lake tops out around 390 ft. The surface is reconstructed from 114 measured spot soundings collected in 1983; water between those measurements is interpolated. Treat the contours between those soundings as a guide, never as 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 6% 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 Main-lake point. It's a point holding about 1 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 | Main-lake point (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | open water | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
Spring puts dolly varden in skinny water — 1 to 30 ft is the zone. Warm water sends them out to 2 to 40 ft; cold water stacks them in 8 to 45 ft. Main-lake point is the standout, a point at roughly 1 ft, rated prime for spring dolly varden. Plan around early morning and the evening in the warm months. A small chrome spoon or a baitfish streamer covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 30 ft | dawn & midday | Main-lake point (1 ft) | Small silver spoon, Inline spinner |
| Summer | 2 to 40 ft | dawn & dusk | Main-lake point (1 ft) | Small chrome spoon, Baitfish streamer |
| Fall | 1 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Small spinner, Egg or fry pattern |
| Winter | 8 to 45 ft | midday | Main-lake point (1 ft) | Small slow spoon, Weighted baitfish fly |
