Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
38-acre lake in East Kootenay Regional District, British Columbia. The lake tops out around 33 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Larchwood Lake runs 38 acres with 1.8 miles of edge. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. About 73% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 0.8 mi long by 0.2 mi wide at the broadest reach. You'll find it in East Kootenay Regional District. For a second option, Johnson Lake lies 1 mi east.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 7 to 33 ft. Break off the point is the standout, a drop-off at roughly 15 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (15 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 33 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 33 ft | dawn | Break off the point (15 ft) | Jigging spoon, Tube jig (white) |
