1,860-acre lake in Kitimat-Stikine Regional District, British Columbia. The lake tops out around 509 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Species by species, here's what the data says the year looks like.
Drawn out, this is 1,860 acres of water rimmed by 9.8 miles of bank. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 0% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 3.7 mi of water from one end to the other, 1.5 mi at the beam. You'll find it in Kitimat-Stikine Regional District. The nearest mapped water is Nass Lake, 19 mi to the east.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Top water on the chart: Shallow bay flat, a feeding flat in the 6 ft range, good in spring. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| 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 (229 ft) | Jigging spoon, Tube jig (white) |
