16-acre lake in Mount Waddington Regional District, British Columbia. The lake tops out around 42 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Species by species, here's what the data says the year looks like.
The drawn water covers 16 acres wrapped in 0.7 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 28% of this chart, as modeled. End to end it runs roughly 0.3 mi. Mount Waddington Regional District claims this one. If the bite dies, Hoomak Lake is 3 mi to the north.
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. As the season builds they drop to 10 to 35 ft, wintering in 10 to 40 ft. Summer cutthroat trout concentrate at Break off the point, a prime-rated drop-off around 19 ft. Warm-month bites cluster around early morning and the evening. 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 (11 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (19 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (11 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (19 ft) | Small jigging spoon, Marabou jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. The chart's best answer is Break off the point — drop-off, 19 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |

| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (11 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (19 ft) | Jigging spoon, Tube jig (white) |
