Rating depth structure for cutthroat trout.
Recent public catches load as you reach this section.
308-acre lake in British Columbia. The lake tops out around 95 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.
Drawn out, this is 307 acres of water rimmed by 4.6 miles of bank. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 12% of this chart, as modeled. Call it 1.8 mi long by 0.5 mi wide at the broadest reach. The water lies in Peace River Regional District. For a second option, Paxton Lake lies 3 mi northwest.
When the water first warms, cutthroat trout slide up into 3 to 15 ft. Summer is a 10 to 35 ft game here, winter a 10 to 40 ft one. Start at Main-lake point. It's a point holding about 24 ft of water and rates prime come fall. The feeding windows run 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 (24 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (24 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (43 ft) | Small jigging spoon, Marabou jig |
