122-acre lake in Fraser-Fort George Regional District, British Columbia. The lake tops out around 122 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Traced from the shoreline, Grayling Lake runs 122 acres with 2.3 miles of edge. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 24% of this chart. Call it 0.9 mi long by 0.4 mi wide at the broadest reach. The water lies in Fraser-Fort George Regional District. The nearest mapped water is Sabai Lake, 5 mi to the southeast.
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 33 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Back-bay flat (19 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (33 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (33 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (33 ft) | Jigging spoon, Tube jig (white) |
