Rating depth structure for rainbow trout.
Recent public catches load as you reach this section.
413-acre lake in British Columbia. The lake tops out around 30 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What the data behind the map says about each species, season by season:
The outline encloses 412 acres, worked by 4.9 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. About 75% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 1.8 mi of water from one end to the other, 0.6 mi at the beam. It sits in Skeena-Queen Charlotte Regional District. If the bite dies, Roy Lake is 4 mi to the south.
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.

When the water first warms, coho salmon slide up into 3 to 25 ft. Summer is a 9 to 30 ft game here, winter a 9 to 30 ft one. Start at Deep basin. It's a deep basin holding about 26 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a dodger + fly or a medium spoon above the thermocline rigged through the warm months.
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 25 ft | dawn & dusk | Main-lake point (8 ft) | Small orange dodger + peanut fly, Thin spoon (orange/silver) |
| Summer | 9 to 30 ft chart-limited; documented 30 to 70 ft | dawn & dusk | Deep basin (26 ft) | Dodger + fly, Medium spoon above the thermocline |
| Fall | 6 to 30 ft chart-limited; documented 8 to 40 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Spinner (chartreuse) |
| Winter | 9 to 30 ft chart-limited; documented 20 to 60 ft | midday | Deep basin (26 ft) | Small spoon, slow troll |
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. Warm water sends them out to 9 to 30 ft; cold water stacks them in 8 to 30 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for fall cutthroat trout. Plan around early morning and the evening in the warm months. 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 | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 9 to 30 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 8 to 30 ft chart-limited; documented 10 to 40 ft | dawn | Deep basin (26 ft) | Small jigging spoon, Marabou jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 6 to 30 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.

| Fall | 9 to 30 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 30 ft chart-limited; documented 8 to 40 ft | dawn | Deep basin (26 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: dolly varden sit in 1 to 30 ft that time of year. They don't go far with the seasons — 2 to 30 ft covers summer, 5 to 30 ft covers winter. Top water on the chart: Main-lake point, a point in the 8 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small chrome spoon or a baitfish streamer until the fish tell you otherwise.

Marian Lake is about 30 ft (9 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 coho salmon, cutthroat trout, rainbow trout, dolly varden on Marian Lake.
Deep basin is the top-rated area: a deep basin in about 26 ft of water that rates prime for coho salmon in summer. Open the map above to see every rated spot for each species and season.
For coho salmon, 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.
