Rating depth structure for rainbow trout.

320-acre lake in Mount Waddington Regional District, British Columbia. The lake tops out around 197 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 320 acres, worked by 6.8 miles of shoreline, with a single island in the mix. That shoreline is heavily fingered (development index 2.7) — bays, points and pockets everywhere, which multiplies the fishable edge. About 3% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 2.6 mi end to end and 0.5 mi across at its widest. It sits in Mount Waddington Regional District. If the bite dies, Benson Lake is 2 mi to the east.
In spring, cutthroat trout run shallow here, mostly 3 to 15 ft. Midsummer fish sit out in 10 to 35 ft before dropping to 10 to 40 ft for winter. Summer cutthroat trout concentrate at Break off the point, a good-rated drop-off around 89 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a trolled spoon (small) or an inline spinner most summer days.
| 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 | Break off the point (89 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (49 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Main-lake point (49 ft) | Small jigging spoon, Marabou jig |
Spring rainbow trout on Kathleen Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. The chart's best answer is Shallow bay flat — feeding flat, 6 ft, good for spring. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |

| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (89 ft) | Jigging spoon, Tube jig (white) |
