Rating depth structure for rainbow trout.

244-acre lake in Fraser-Fort George Regional District, British Columbia. The lake tops out around 52 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Terrapin Lake runs 244 acres with 3.7 miles of edge. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. About 69% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 1.1 mi end to end and 0.7 mi across at its widest. The water lies in Fraser-Fort George Regional District. The nearest mapped water is Racoon Lake, 3 mi to the south.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 8 to 40 ft for winter. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 1 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
| 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 | Break off the point (1 ft) | 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 | Break off the point (1 ft) | Jigging spoon, Tube jig (white) |
Spring lake whitefish on Terrapin Lake hold shallow, usually 15 to 45 ft. By summer they slide out to 16 to 52 ft, and by winter most fish are in 16 to 52 ft. The chart's best answer is Deep basin — deep basin, 49 ft, prime for summer. Prime time lands in early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 16 to 52 ft | dawn | Deep basin (49 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (1 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 16 to 52 ft | midday & dawn | Deep basin (49 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
