4,795-acre lake in British Columbia. The lake tops out around 230 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 4,784 acres wrapped in 34.7 miles of bank. With a shoreline index of 3.6, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 29% of the water is 15 ft or less as modeled, the band where the food chain lives.
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 Sharp break: a drop-off around 20 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 | 5 to 20 ft | dawn & dusk | Sharp break (20 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Sharp break (20 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Shoreline point (22 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Sharp break (20 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. Offshore hump is the standout, a offshore hump at roughly 33 ft, rated prime for winter 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 | Offshore hump (33 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Offshore hump (33 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (2 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Offshore hump (33 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
