157-acre lake in Bulkley-Nechako Regional District, British Columbia. The lake tops out around 90 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Guess Lake runs 157 acres with 2.6 miles of edge. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. 26% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 1 mi with a 0.5-mi widest point. You'll find it in Bulkley-Nechako Regional District. For a second option, Deception Lake lies 3 mi southeast.
When the water first warms, cutthroat trout slide up into 3 to 15 ft. By summer they slide out to 10 to 35 ft, and by winter most fish are in 10 to 40 ft. If you only fish one area, make it Main-lake point: a point around 23 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a trolled spoon (small) or an inline spinner rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Main-lake point (23 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (23 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (41 ft) | Small jigging spoon, Marabou jig |
