Rating depth structure for cutthroat trout.

16-acre lake in British Columbia. The lake tops out around 80 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 16 acres of water rimmed by 0.6 miles of bank. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 12% of this chart, as modeled. The water lies in East Kootenay Regional District. The nearest mapped water is Wall Lake, 1 mi to the west.
Early season cutthroat trout use the shallows, holding in 3 to 15 ft. Summer is a 10 to 35 ft game here, winter a 10 to 40 ft one. The chart's best answer is Shoreline break — drop-off, 36 ft, prime for summer. Best bite is early morning and the evening. Tie on a trolled spoon (small) or an inline spinner and you're in the game.
| 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 | Shoreline break (36 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | open water | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Shoreline break (36 ft) | Small jigging spoon, Marabou jig |
