480-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 130 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. What the data behind the map says about each species, season by season:
Traced from the shoreline, Horn Lake runs 480 acres with 6.1 miles of edge — one island included. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. 9% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 2.5 mi, about 0.9 mi across. You'll find it in Cariboo Regional District. Closest neighbour on DepthScout: Sapeye Lake, 2 mi southwest of here.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 8 to 40 ft. The spot to know is Main-lake point, a point in about 33 ft of water that rates prime for rainbow trout in fall. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| 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 |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (33 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (33 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (59 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 111 ft.
