1,583-acre lake in Fraser-Fort George Regional District, British Columbia. The lake tops out around 120 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. What follows comes from the same scoring engine that paints the spots above.
On the chart, Tudyah Lake draws 1,583 acres inside 16.2 miles of shoreline. The 2.9 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 33% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 3.7 mi, about 1.8 mi across. The water lies in Fraser-Fort George Regional District. Closest neighbour on DepthScout: Sabai Lake, 2 mi west of here.
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. Fall rainbow trout concentrate at Main-lake point, a prime-rated point around 30 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 | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (30 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (30 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (54 ft) | Jigging spoon, Tube jig (white) |
Spring lake whitefish on Tudyah Lake hold shallow, usually 15 to 45 ft. By summer they slide out to 40 to 90 ft, and by winter most fish are in 25 to 70 ft. The chart's best answer is Break off the point — drop-off, 54 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 | Break off the point (54 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Break off the point (54 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (30 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Break off the point (54 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
