470-acre lake in Kitimat-Stikine Regional District, British Columbia. The lake tops out around 89 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 the data behind the map says about each species, season by season:
Drawn out, this is 470 acres of water rimmed by 4.9 miles of bank. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 8% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 1.8 mi long by 0.5 mi wide at the broadest reach. You'll find it in Kitimat-Stikine Regional District. Closest neighbour on DepthScout: Halfmoon Lake, 14 mi east of here.
The spring pattern is a shallow one: arctic grayling in 2 to 10 ft. As the season builds they drop to 3 to 15 ft, wintering in 8 to 25 ft. Top water on the chart: Shallow bay flat, a feeding flat in the 6 ft range, prime in summer. Time it for the evening and early morning. Summer baits: a dry fly (parachute adams, elk hair caddis) or a small inline spinner gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dusk | Shallow bay flat (6 ft) | 1/16 oz spinner (silver), Small dry fly (Adams, Griffith's) |
| Summer | 3 to 15 ft | dusk & dawn | Shallow bay flat (6 ft) | Dry fly (parachute Adams, elk hair caddis), Small inline spinner |
| Fall | 6 to 20 ft | midday | Break off the point (40 ft) | Small spoon, Beadhead nymph under indicator |
| Winter | 8 to 25 ft | midday & dawn | Shallow bay flat (6 ft) | Tungsten jig + waxworm, Small jigging spoon (gold) |
