Rating depth structure for rainbow trout.

153-acre lake in Fraser-Fort George Regional District, British Columbia. The lake tops out around 56 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 153 acres wrapped in 3.7 miles of bank. A development index of 2.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. 35% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 1.5 mi long by 0.4 mi wide at the broadest reach. Fraser-Fort George Regional District claims this one. Its nearest charted neighbour, Kaminski Lake, is 3 mi to the east.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 25 ft that scores prime in winter. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (14 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (25 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (14 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (25 ft) | Jigging spoon, Tube jig (white) |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. Warm water sends them out to 17 to 56 ft; cold water stacks them in 17 to 56 ft. Deep basin is the standout, a deep basin at roughly 48 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (25 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 17 to 56 ft | dawn | Deep basin (48 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (25 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 17 to 56 ft | midday & dawn | Deep basin (48 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
