612-acre lake in Fraser-Fort George Regional District, British Columbia. The lake tops out around 77 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Dahl Lake runs 612 acres with 11.5 miles of edge — 4 islands included. With a shoreline index of 3.3, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 66% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 2 mi end to end and 1.7 mi across at its widest. The water lies in Fraser-Fort George Regional District. Closest neighbour on DepthScout: Norman Lake, 3 mi west of here.
Spring puts burbot in skinny water — 25 to 70 ft is the zone. As the season builds they drop to 23 to 77 ft, wintering in 15 to 60 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 65 ft. Warm-month bites cluster around after dark and midday. A heavy jig + cut bait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (65 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 23 to 77 ft | night & midday | Deep basin (65 ft) | Heavy jig + cut bait |
| Fall | 23 to 77 ft | night & dusk | Deep basin (65 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (65 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
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 35 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 | Main-lake point (19 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (19 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (19 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (35 ft) | Jigging spoon, Tube jig (white) |
Early season lake whitefish use the shallows, holding in 15 to 45 ft. Expect a summer slide to 23 to 77 ft, then a winter hold in 25 to 70 ft. Put Deep basin first on the milk run — a deep basin near 65 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (35 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 23 to 77 ft | dawn | Deep basin (65 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (19 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (65 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
