6-acre lake in Fraser Valley Regional District, British Columbia. The lake tops out around 35 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. What the data behind the map says about each species, season by season:
The drawn water covers 6 acres wrapped in 0.4 miles of bank. Nearly circular (index 1), so the story is the bottom, not the bank. 31% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Fraser Valley Regional District claims this one. If the bite dies, Sardis Pond is 4 mi to the west.
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. As the season builds they drop to 10 to 35 ft, wintering in 9 to 35 ft. Summer cutthroat trout concentrate at Shoreline break, a prime-rated drop-off around 16 ft. Warm-month bites cluster around early morning and the evening. A trolled spoon (small) or an inline spinner covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Shoreline break (16 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Shoreline break (16 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Shoreline break (16 ft) | Casting spoon, Inline spinner |
| Winter | 9 to 35 ft | dawn | Shoreline break (16 ft) | Small jigging spoon, Marabou jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter a 7 to 35 ft one. The chart's best answer is Shoreline break — drop-off, 16 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
