167-acre lake in British Columbia. The lake tops out around 230 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Sarah Lake runs 166 acres with 2.9 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Roughly 3% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 1.2 mi, about 0.3 mi across. You'll find it in Skeena-Queen Charlotte Regional District. For a second option, Bill Lake lies 8 mi southeast.
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Spring rainbow trout concentrate at Shallow bay flat, a good-rated feeding flat around 6 ft. Warm-month bites cluster around early morning and the evening. 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 | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | open water | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
In spring, kokanee run shallow here, mostly 10 to 30 ft. Summer pushes them deeper, 30 to 70 ft, and winter fish settle into 20 to 80 ft. Time it for early morning. You won't need more than a dodger + pink/orange squid on downrigger or a kokanee bug + corn most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | open water | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | open water | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | open water | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | open water | Small glow jig + corn or maggot, Tiny spoon |
Early season lake whitefish use the shallows, holding in 15 to 45 ft. Summer is a 40 to 90 ft game here, winter a 25 to 70 ft one. The chart's best answer is Break off the point — drop-off, 104 ft, good for summer. Best bite is 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 | Shallow bay flat (6 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Break off the point (104 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | open water | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | open water | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts burbot in skinny water — 25 to 70 ft is the zone. Warm water sends them out to 50 to 120 ft; cold water stacks them in 15 to 60 ft. Break off the point is the standout, a drop-off at roughly 104 ft, rated good for summer burbot. Plan around after dark and midday in the warm months. 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 | open water | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Break off the point (104 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | open water | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | open water | Glow tungsten + cut bait, Rattle spoon + minnow head |

Sarah Lake is about 230 ft (70 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target rainbow trout, kokanee, lake whitefish, burbot on Sarah Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Break off the point is the top-rated area: a drop-off in about 104 ft of water that rates good for burbot in summer. The interactive chart above rates every spot for each species and season.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
