212-acre lake in Peace River Regional District, British Columbia. The lake tops out around 107 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Fern Lake runs 212 acres with 3.7 miles of edge. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 34% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 1 mi long by 0.7 mi wide at the broadest reach. You'll find it in Peace River Regional District. For a second option, Chesterfield Lake lies 9 mi west.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. The spot to know is Break off the point, a drop-off in about 33 ft of water that rates prime for rainbow trout in winter. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (2 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (33 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (33 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (33 ft) | Jigging spoon, Tube jig (white) |
