48-acre lake in Fraser-Fort George Regional District, British Columbia. The lake tops out around 108 ft. The surface is reconstructed from 116 measured spot soundings collected in 1989; water between those measurements is interpolated. Treat the contours between those soundings as a guide, never as navigation. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 48 acres wrapped in 1.2 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. About 19% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.4 mi end to end and 0.3 mi across at its widest. It sits in Fraser-Fort George Regional District. Its nearest charted neighbour, Dina Lakes, is 5 mi to the southeast.
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Put Main-lake point first on the milk run — a point near 1 ft that grades good for spring. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (1 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | open water | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
Pothole Lakes carries 5 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 108 ft down.
