328-acre lake in Peace River Regional District, British Columbia. The lake tops out around 39 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. Species by species, here's what the data says the year looks like.
The outline encloses 328 acres, worked by 4.9 miles of shoreline. A middling shoreline index (1.9) gives it some bays to work without being a maze. 57% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 2 mi long by 0.5 mi wide at the broadest reach. Peace River Regional District claims this one. If the bite dies, Fredrikson Lake is 10 mi to the northeast.
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 39 ft one. Start at Break off the point. It's a drop-off holding about 18 ft of water and rates prime come winter. 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 | Main-lake point (10 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (18 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 39 ft | dawn | Break off the point (18 ft) | Jigging spoon, Tube jig (white) |
In spring, lake whitefish run shallow here, mostly 12 to 39 ft. Summer keeps them at 12 to 39 ft, and they winter in 12 to 39 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 33 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 | 12 to 39 ft | midday & dawn | Break off the point (18 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 12 to 39 ft | dawn | Deep basin (33 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (18 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 12 to 39 ft | midday & dawn | Deep basin (33 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
