Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
392-acre lake in British Columbia. The lake tops out around 59 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.
The outline encloses 391 acres, worked by 5.4 miles of shoreline. With a 2 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 62% of this chart. Call it 2.2 mi long by 0.4 mi wide at the broadest reach. It sits in Central Kootenay Regional District. If the bite dies, Box Lake is 5 mi to the northwest.

Spring brook trout on Summit Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Secondary point — point, 8 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Back-bay flat (2 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. Warm water sends them out to 10 to 35 ft; cold water stacks them in 10 to 40 ft. Secondary point is the standout, a point at roughly 8 ft, rated prime for fall cutthroat trout. Plan around early morning and the evening in the warm months. A trolled spoon (small) or an inline spinner covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Secondary point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Secondary point (8 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Secondary point (8 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Secondary point (8 ft) | Small jigging spoon, Marabou jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Put Secondary point first on the milk run — a point near 8 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Secondary point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Secondary point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Secondary point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Deep basin (49 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: dolly varden sit in 1 to 30 ft that time of year. Warm water sends them out to 2 to 40 ft; cold water stacks them in 8 to 45 ft. Top water on the chart: Main-lake point, a point in the 1 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small chrome spoon or a baitfish streamer until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 30 ft | dawn & midday | Main-lake point (1 ft) | Small silver spoon, Inline spinner |
| Summer | 2 to 40 ft | dawn & dusk | Secondary point (8 ft) | Small chrome spoon, Baitfish streamer |
| Fall | 1 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Small spinner, Egg or fry pattern |
| Winter | 8 to 45 ft | midday | Secondary point (8 ft) | Small slow spoon, Weighted baitfish fly |
