13-acre lake in Squamish-Lillooet Regional District, British Columbia. The lake tops out around 43 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Mosquito Lake maps at 13 acres behind 0.6 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. The shallow band under 15 ft claims about 52% of the surface — that's where the groceries are. Tip to tip the water measures near 0.3 mi. It sits in Squamish-Lillooet Regional District. Its nearest charted neighbour, Ivey Lake, is 0 mi to the west.
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. Warm water sends them out to 10 to 35 ft; cold water stacks them in 10 to 40 ft. Break off the point is the standout, a drop-off at roughly 31 ft, rated prime for summer cutthroat trout. Plan around early morning and the evening in the warm months. A trolled spoon (small) or an inline spinner covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (14 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (31 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (14 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (31 ft) | Small jigging spoon, Marabou jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Put Break off the point first on the milk run — a drop-off near 31 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
