17,122-acre lake in Central Kootenay Regional District, British Columbia. The lake tops out around 978 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Species by species, here's what the data says the year looks like.
The outline encloses 17,025 acres, worked by 54 miles of shoreline. An index of 3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 0% of this chart, as modeled. End to end it runs roughly 22.2 mi, about 6.1 mi across. Central Kootenay Regional District claims this one. If the bite dies, Wee Sandy Lake is 7 mi to the northwest.
When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. Start at Creek inflow. It's an inflow / creek mouth holding about 8 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Creek inflow (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Creek inflow (8 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Creek inflow (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Creek inflow (8 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season burbot use the shallows, holding in 25 to 70 ft. Summer is a 50 to 120 ft game here, winter a 15 to 60 ft one. The chart's best answer is Offshore hump — offshore hump, 113 ft, prime for summer. 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 | 25 to 70 ft | night & dusk | Deep basin (831 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Offshore hump (113 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (831 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Offshore hump (150 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Start shallow in spring: cutthroat trout sit in 3 to 15 ft that time of year. Summer pushes them deeper, 10 to 35 ft, and winter fish settle into 10 to 40 ft. The spot to know is Creek inflow, an inflow / creek mouth in about 8 ft of water that rates prime for cutthroat trout in spring. Warm-month bites cluster around early morning and the evening. Throw a trolled spoon (small) or an inline spinner until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Creek inflow (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Creek inflow (8 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Creek inflow (8 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Creek inflow (8 ft) | Small jigging spoon, Marabou jig |
When the water first warms, kokanee slide up into 10 to 30 ft. Summer is a 30 to 70 ft game here, winter a 20 to 80 ft one. Start at Creek inflow. It's an inflow / creek mouth holding about 8 ft of water and rates prime come fall. 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 | 10 to 30 ft | dawn | Deep basin (831 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Deep basin (831 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Creek inflow (8 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Deep basin (831 ft) | Small glow jig + corn or maggot, Tiny spoon |
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. If you only fish one area, make it Creek inflow: an inflow / creek mouth around 8 ft that scores prime in spring. 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 | 5 to 20 ft | dawn & dusk | Creek inflow (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Creek inflow (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Creek inflow (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Creek inflow (8 ft) | Jigging spoon, Tube jig (white) |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. Warm water sends them out to 40 to 90 ft; cold water stacks them in 25 to 70 ft. Deep basin is the standout, a deep basin at roughly 831 ft, rated good 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 | 15 to 45 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Deep basin (831 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | open water | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (831 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Structure-wise the chart holds 16 features, led in depth by Deep basin at roughly 831 ft.
