79-acre lake in Fraser-Fort George Regional District, British Columbia. The lake tops out around 16 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Species by species, here's what the data says the year looks like.
Frost Lake maps at 79 acres behind 2.2 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 86% of this chart, as modeled. Call it 0.9 mi long by 0.3 mi wide at the broadest reach. It sits in Fraser-Fort George Regional District. Its nearest charted neighbour, Francis Lake, is 2 mi to the south.
Come spring, look for rainbow trout tight to the bank in 4 to 16 ft. Through summer count on 4 to 16 ft; the winter hold is 3 to 16 ft. Start at Break off the point. It's a drop-off holding about 7 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 4 to 16 ft | dawn & dusk | Break off the point (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 16 ft | dawn | Break off the point (7 ft) | Jigging spoon, Tube jig (white) |
