5,951-acre lake in East Kootenay Regional District, British Columbia. The lake tops out around 17 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The rest of this page walks each species through its year, using the map's own scoring.
Columbia Lake maps at 5,949 acres behind 26.6 miles of shoreline. The 2.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 90% of this chart, as modeled. Call it 9.6 mi long by 1.9 mi wide at the broadest reach. East Kootenay Regional District claims this one. Whitetail Lake sits 8 mi west — the closest neighbouring chart.
Early season burbot use the shallows, holding in 5 to 17 ft. Even in summer they hold at 5 to 17 ft; winter keeps them in 4 to 17 ft. The chart's best answer is Deep basin — deep basin, 14 ft, prime for spring. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 17 ft | night & dusk | Deep basin (14 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 5 to 17 ft | night & midday | Deep basin (14 ft) | Heavy jig + cut bait |
| Fall | 5 to 17 ft | night & dusk | Deep basin (14 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 4 to 17 ft | night & dusk | Deep basin (14 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
When the water first warms, kokanee slide up into 5 to 17 ft. There's no big seasonal slide here — summer means 5 to 17 ft, winter 4 to 17 ft. Start at Deep basin. It's a deep basin holding about 14 ft of water and rates prime come spring. The feeding windows run early morning. Keep a dodger + pink/orange squid on downrigger or a kokanee bug + corn rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 17 ft | dawn | Deep basin (14 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 5 to 17 ft | dawn | Deep basin (14 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 2 to 17 ft | dawn | Deep basin (14 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 4 to 17 ft | dawn | Deep basin (14 ft) | Small glow jig + corn or maggot, Tiny spoon |
Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 10 ft; cold water stacks them in 5 to 17 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring pumpkinseed. Plan around the evening and early morning in the warm months. A micro tube or a sponge spider (fly) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Weed flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 17 ft | dawn | Weed flat (5 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for rainbow trout tight to the bank in 4 to 17 ft. Through summer count on 5 to 17 ft; the winter hold is 3 to 17 ft. If you only fish one area, make it Break off the point: a drop-off around 8 ft that scores prime in winter. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 17 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 17 ft | dawn & dusk | Break off the point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 17 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 17 ft | dawn | Break off the point (8 ft) | Jigging spoon, Tube jig (white) |
Spring puts lake whitefish in skinny water — 5 to 17 ft is the zone. Summer fish stay in 5 to 17 ft, and winter fish hold in 5 to 17 ft. Deep basin is the standout, a deep basin at roughly 14 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 17 ft | midday & dawn | Break off the point (8 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 5 to 17 ft | dawn | Deep basin (14 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 5 to 17 ft | dusk | Break off the point (8 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 5 to 17 ft | midday & dawn | Deep basin (14 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
