Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
59-acre lake in British Columbia. The lake tops out around 13 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 59 acres of water rimmed by 1.8 miles of bank. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 0.7 mi end to end and 0.2 mi across at its widest. You'll find it in Strathcona Regional District. The nearest mapped water is Second Lake, 1 mi to the south.
In spring, rainbow trout run shallow here, mostly 3 to 13 ft. Summer keeps them at 3 to 13 ft, and they winter in 3 to 13 ft. Break off the point is the standout, a drop-off at roughly 6 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 13 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 3 to 13 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 4 to 13 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 3 to 13 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (6 ft) | Jigging spoon, Tube jig (white) |
5 pieces of structure are mapped here — Deep basin, around 11 ft, is the deepest of them.
Season dates, license requirements, and size and bag limits for British Columbia waters are set by the BC freshwater fishing synopsis — and special regulations can apply to Third Lake specifically, so confirm the current rules before you fish.

Third Lake is about 13 ft (4 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target rainbow trout on Third Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Break off the point is the top-rated area: a drop-off in about 6 ft of water that rates prime for rainbow trout in winter. Scroll up to the map for the complete spot list by species and season.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
