4,180-acre lake in Central Kootenay Regional District, British Columbia. The lake tops out around 381 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. The season-by-season read for each species follows, from the map's own numbers.
Whatshan Lake maps at 4,344 acres behind 35 miles of shoreline — 6 islands included. The 3.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 0% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 12.3 mi end to end and 1.8 mi across at its widest. Central Kootenay Regional District claims this one. Snowshoe Lake sits 7 mi southwest — the closest neighbouring chart.
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: an offshore hump around 45 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 (324 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Offshore hump (45 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 (45 ft) | Small glow jig + corn or maggot, Tiny spoon |
When the water first warms, rainbow trout slide up into 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. Start at Shallow bay flat. It's a feeding 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 | Break off the point (171 ft) | Jigging spoon, Tube jig (white) |
In spring, lake whitefish run shallow here, mostly 15 to 45 ft. Midsummer fish sit out in 40 to 90 ft before dropping to 25 to 70 ft for winter. Summer lake whitefish concentrate at Offshore hump, a prime-rated offshore hump around 45 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Offshore hump (45 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Offshore hump (45 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 | Offshore hump (45 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |

Whatshan Lake is about 381 ft (116 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target kokanee, rainbow trout, lake whitefish on Whatshan Lake.
Offshore hump is the top-rated area: an offshore hump in about 45 ft of water that rates prime for lake whitefish in summer. The interactive chart above rates every spot for each species and season.
For kokanee, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
