Fishing Alty Lake: what the data says
445-acre lake in British Columbia. The lake tops out around 427 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What follows comes from the same scoring engine that paints the spots above.
Alty Lake maps at 444 acres behind 4.5 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. About 0% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone.
Rainbow Trout fishing at Alty Lake
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 Shallow bay flat first on the milk run — a weed flat near 6 ft that grades good 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 | 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 | Break off the point (192 ft) | Jigging spoon, Tube jig (white) |
Kokanee fishing at Alty Lake
Spring kokanee on Alty Lake hold shallow, usually 10 to 30 ft. By summer they slide out to 30 to 70 ft, and by winter most fish are in 20 to 80 ft. The chart's best answer is Deep basin — deep basin, 363 ft, good for spring. Prime time lands in early morning. The summer box starts with a dodger + pink/orange squid on downrigger or a kokanee bug + corn.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Deep basin (363 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Deep basin (363 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |

| Winter | 20 to 80 ft | dawn | Deep basin (363 ft) | Small glow jig + corn or maggot, Tiny spoon |
Lake Whitefish fishing at Alty Lake
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. As the season builds they drop to 40 to 90 ft, wintering in 25 to 70 ft. Top water on the chart: Deep basin, a deep basin in the 363-ft range, good in summer. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Deep basin (363 ft) | Blade bait vertical, Small jigging spoon |

Burbot fishing at Alty Lake
Come spring, look for burbot tight to the bank in 25 to 70 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 15 to 60 ft. Start at Deep basin. It's a deep basin holding about 363 ft of water and rates good come spring. Prime time lands in after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (363 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
