42-acre lake in British Columbia. The lake tops out around 44 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 42 acres, worked by 1 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 23% of this chart, as modeled. End to end it runs roughly 0.4 mi, about 0.3 mi across. Cariboo Regional District claims this one. Hudson Lake sits 2 mi southwest — the closest neighbouring chart.

When the water first warms, rainbow trout slide up into 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. Start at Break off the point. It's a drop-off holding about 20 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (11 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (20 ft) | Dodger + spoon (deep troll), Flutter spoon |
| 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 (20 ft) | Jigging spoon, Tube jig (white) |
