100-acre lake in Mount Waddington Regional District, British Columbia. The lake tops out around 128 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. What the data behind the map says about each species, season by season:
On the chart, O'Connor Lake draws 100 acres inside 2.2 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. The shallow band under 15 ft claims about 10% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 1 mi with a 0.2-mi widest point. The water lies in Mount Waddington Regional District. For a second option, Keogh Lake lies 5 mi southeast.
When the water first warms, cutthroat trout slide up into 3 to 15 ft. Summer is a 10 to 35 ft game here, winter a 10 to 40 ft one. Start at Main-lake point. It's a point holding about 32 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a trolled spoon (small) or an inline spinner rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Main-lake point (32 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (32 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Main-lake point (32 ft) | Small jigging spoon, Marabou jig |
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 32 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 (32 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (32 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (58 ft) | Jigging spoon, Tube jig (white) |
