Rating depth structure for rainbow trout.

401-acre lake near Cole Bay. The lake tops out around 61 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The rest of this page walks each species through its year, using the map's own scoring.
Fern Lake maps at 400 acres behind 5.5 miles of shoreline, with 2 islands in the mix. A middling shoreline index (2) gives it some bays to work without being a maze. About 53% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 1.2 mi long by 0.8 mi wide at the broadest reach. Division No. 18 claims this one. Its nearest charted neighbour, Atchison Lake, is 1 mi to the northwest.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 27 ft that scores prime in winter. Best bite is 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 | 5 to 20 ft | dawn & dusk | Main-lake point (15 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (27 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (27 ft) | Jigging spoon, Tube jig (white) |
Spring splake on Fern Lake hold shallow, usually 5 to 25 ft. They move out to 25 to 60 ft in summer and finish the year down in 10 to 45 ft. Put Break off the point first on the milk run — a drop-off near 27 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a trolled spoon at the thermocline or a white tube jig (deep).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (15 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (27 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (15 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (27 ft) | Jigging spoon tipped with minnow head, Small white tube |
