306-acre lake in Kitimat-Stikine Regional District, British Columbia. The lake tops out around 39 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 306 acres of water rimmed by 5.6 miles of bank. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. The shallow band under 15 ft claims about 43% of the surface on the model — that's where the groceries are. Figure 1.7 mi of water from one end to the other, 0.7 mi at the beam. You'll find it in Kitimat-Stikine Regional District. For a second option, Tumeka Lake lies 19 mi west.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 39 ft. The spot to know is Break off the point, a drop-off in about 18 ft of water that rates prime for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (10 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (18 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 39 ft | dawn | Break off the point (18 ft) | Jigging spoon, Tube jig (white) |
