14,342-acre lake in British Columbia. The lake tops out around 625 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What the data behind the map says about each species, season by season:
The drawn water covers 14,311 acres wrapped in 68 miles of bank. A development index of 4.1 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 0% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone.
Come spring, look for kokanee tight to the bank in 10 to 30 ft. They move out to 30 to 70 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Offshore hump: a offshore hump around 70 ft that scores prime in summer. Best bite is early morning. A dodger + pink/orange squid on downrigger or a kokanee bug + corn is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Deep basin (531 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Offshore hump (70 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | open water | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Offshore hump (70 ft) | Small glow jig + corn or maggot, Tiny spoon |
Spring lake trout on Horsefly Lake hold shallow, usually 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. Put Offshore hump first on the milk run — a offshore hump near 70 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (156 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Offshore hump (70 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Offshore hump (60 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Offshore hump (70 ft) | White tube jig, Airplane jig |
When the water first warms, rainbow trout slide up into 5 to 20 ft. Summer is a 8 to 30 ft game here, winter a 8 to 40 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates good come spring. The feeding windows run early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| 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 | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Deep break (59 ft) | Jigging spoon, Tube jig (white) |
