8,727-acre lake in Squamish-Lillooet Regional District, British Columbia. The lake tops out around 427 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 7,993 acres, worked by 38.8 miles of shoreline, broken up by 3 islands. The 3.1 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 0% of this chart, as modeled. Call it 12.8 mi long by 4.8 mi wide at the broadest reach. It sits in Squamish-Lillooet Regional District. If the bite dies, Little Lillooet Lake is 9 mi to the south.
In spring, cutthroat trout run shallow here, mostly 3 to 15 ft. Midsummer fish sit out in 10 to 35 ft before dropping to 10 to 40 ft for winter. Summer cutthroat trout concentrate at Sharp break, a good-rated drop-off around 156 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a trolled spoon (small) or an inline spinner most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Sharp break (156 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (107 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Sharp break (156 ft) | Small jigging spoon, Marabou jig |
Early season kokanee use the shallows, holding in 10 to 30 ft. Expect a summer slide to 30 to 70 ft, then a winter hold in 20 to 80 ft. Put Offshore hump first on the milk run — an offshore hump near 45 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a dodger + pink/orange squid on downrigger or a kokanee bug + corn and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Deep basin (363 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Offshore hump (45 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | open water | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Offshore hump (45 ft) | Small glow jig + corn or maggot, Tiny spoon |
Spring rainbow trout on Lillooet Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. The chart's best answer is Shallow bay flat — feeding flat, 6 ft, good for spring. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| 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 | Sharp break (156 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: lake whitefish sit in 15 to 45 ft that time of year. Summer pushes them deeper, 40 to 90 ft, and winter fish settle into 25 to 70 ft. The spot to know is Offshore hump, an offshore hump in about 45 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Offshore hump (45 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Offshore hump (45 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | open water | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Offshore hump (45 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
