295-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 66 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Traced from the shoreline, 108 Mile Lake runs 368 acres with 4.8 miles of edge. The shoreline is moderately structured (index 1.8) — enough points and pockets to pattern. Roughly 40% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 1.3 mi, about 0.9 mi across. The water lies in Cariboo Regional District. The nearest mapped water is Sepa Lake, 1 mi to the southeast.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 15 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (15 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Break off the point is the standout, a drop-off at roughly 15 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
