Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
21-acre lake in British Columbia. The lake tops out around 20 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
Drawn out, this is 21 acres of water rimmed by 0.7 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. 86% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. The water lies in Capital Regional District. The nearest mapped water is Blenkinsop Lake, 1 mi to the northeast.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Come spring, look for cutthroat trout tight to the bank in 3 to 15 ft. They move out to 6 to 20 ft in summer and finish the year down in 5 to 20 ft. If you only fish one area, make it Shoreline break: a drop-off around 9 ft that scores prime in summer. Best bite is early morning and the evening. A trolled spoon (small) or an inline spinner is the honest summer answer here.
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 15 ft | dawn & dusk | Shoreline break (9 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 6 to 20 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Shoreline break (9 ft) | Trolled spoon (small), Inline spinner |
| Fall | 4 to 20 ft chart-limited; documented 5 to 25 ft | dawn & dusk | Shoreline break (9 ft) | Casting spoon, Inline spinner |
| Winter | 5 to 20 ft chart-limited; documented 10 to 40 ft | dawn | Shoreline break (9 ft) | Small jigging spoon, Marabou jig |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 6 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (17 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Summer fish stay in 5 to 20 ft, and winter fish hold in 4 to 20 ft. Shoreline break is the standout, a drop-off at roughly 9 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shoreline break (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 20 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Shoreline break (9 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 20 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Shoreline break (9 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 20 ft chart-limited; documented 8 to 40 ft | dawn | Shoreline break (9 ft) | Jigging spoon, Tube jig (white) |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 6 to 20 ft. Deep basin is the standout, a deep basin at roughly 17 ft, rated prime for winter brown bullhead. Time it for after dark and the evening.

Swan Lake is about 20 ft (6 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 cutthroat trout, pumpkinseed, rainbow trout, brown bullhead on Swan Lake.
Shoreline break is the top-rated area: a drop-off in about 9 ft of water that rates prime for cutthroat trout in summer. Scroll up to the map for the complete spot list by species and season.
For cutthroat 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.
