Rating depth structure for cutthroat trout.
Recent public catches load as you reach this section.
364-acre lake in British Columbia. The lake tops out around 171 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. What the data behind the map says about each species, season by season:
Drawn out, this is 364 acres of water rimmed by 4.6 miles of bank. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. The shallow band under 15 ft claims about 3% of the surface on the model — that's where the groceries are. End to end it runs roughly 1.8 mi, about 0.6 mi across. You'll find it in Kitimat-Stikine Regional District. Closest neighbour on DepthScout: Whalen Lake, 17 mi southwest of here.

Come spring, look for cutthroat trout tight to the bank in 3 to 15 ft. Expect a summer slide to 10 to 35 ft, then a winter hold in 10 to 40 ft. Start at Main-lake point. It's a point holding about 43 ft of water and rates good come winter. Prime time lands in early morning and the evening. A trolled spoon (small) or an inline spinner is the honest summer answer here.
| 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 | Main-lake point (43 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | open water | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Main-lake point (43 ft) | Small jigging spoon, Marabou jig |
Come spring, look for dolly varden tight to the bank in 1 to 30 ft. They move out to 2 to 40 ft in summer and finish the year down in 8 to 45 ft. If you only fish one area, make it Main-lake point: a point around 43 ft that scores prime in summer. Best bite is early morning and the evening. A small chrome spoon or a baitfish streamer is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 30 ft | dawn & midday | Main-lake point (43 ft) | Small silver spoon, Inline spinner |
| Summer | 2 to 40 ft | dawn & dusk | Main-lake point (43 ft) | Small chrome spoon, Baitfish streamer |
| Fall | 1 to 25 ft | dawn & dusk | open water | Small spinner, Egg or fry pattern |
| Winter | 8 to 45 ft | midday | Main-lake point (43 ft) | Small slow spoon, Weighted baitfish fly |
