13,725-acre lake near Omineca, BC. The lake tops out around 221 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.
On the chart, Pinchi Lake draws 13,740 acres inside 41.4 miles of shoreline, with 3 islands in the mix. An index of 2.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 14% of this chart. The basin spans about 14.2 mi end to end and 3.4 mi across at its widest. You'll find it in Bulkley-Nechako Regional District. Closest neighbour on DepthScout: Tezzeron Lake, 8 mi north of here.
The spring pattern is a shallow one: brown bullhead in 2 to 8 ft. Midsummer fish sit out in 3 to 12 ft before dropping to 10 to 25 ft for winter. The spot to know is Shallow bay flat, a feeding flat in about 7 ft of water that rates prime for brown bullhead in summer. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (7 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (7 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (7 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (219 ft) |
Start shallow in spring: burbot sit in 25 to 70 ft that time of year. Warm water sends them out to 50 to 120 ft; cold water stacks them in 15 to 60 ft. Top water on the chart: Rock reef, a rock pile in the 6 ft range, prime in winter. Fish it in after dark and midday and you'll meet the bite. Throw a heavy jig + cut bait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (41 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Sharp break (50 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (41 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Rock reef (6 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Start shallow in spring: kokanee sit in 10 to 30 ft that time of year. Summer pushes them deeper, 30 to 70 ft, and winter fish settle into 20 to 80 ft. The spot to know is Break off the point, a drop-off in about 41 ft of water that rates prime for kokanee in summer. Warm-month bites cluster around early morning. Throw a dodger + pink/orange squid on downrigger or a kokanee bug + corn until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 30 ft | dawn | Sharp break (9 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 30 to 70 ft | dawn | Break off the point (41 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 5 to 40 ft | dawn | Sharp break (9 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 20 to 80 ft | dawn | Break off the point (41 ft) | Small glow jig + corn or maggot, Tiny spoon |
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 50 to 120 ft; cold water stacks them in 20 to 80 ft. Top water on the chart: Secondary point, a point in the 30 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Secondary point (30 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Sharp break (50 ft) | White tube jig (deep), Magnum spoon on downrigger |

| Winter | 20 to 80 ft | dawn | Break off the point (41 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Top water on the chart: Sharp break, a drop-off in the 9 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (5 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Sharp break (9 ft) | Dodger + spoon (deep troll), Flutter spoon |

When the water first warms, lake whitefish slide up into 15 to 45 ft. Summer is a 40 to 90 ft game here, winter a 25 to 70 ft one. Start at Rock reef. It's a rock pile holding about 6 ft of water and rates prime come fall. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (41 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Break off the point (41 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Rock reef (6 ft) | Small spoon (gold), Jig + plastic larva |
