170-acre lake in Skeena-Queen Charlotte Regional District, British Columbia. The lake tops out around 26 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. The season-by-season read for each species follows, from the map's own numbers.
Roy Lake maps at 170 acres behind 3.2 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. 82% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 1.2 mi end to end and 0.3 mi across at its widest. It sits in Skeena-Queen Charlotte Regional District. Its nearest charted neighbour, Marian Lake, is 4 mi to the north.
Start shallow in spring: cutthroat trout sit in 3 to 15 ft that time of year. Warm water sends them out to 7 to 26 ft; cold water stacks them in 7 to 26 ft. Top water on the chart: Break off the point, a drop-off in the 12 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a trolled spoon (small) or an inline spinner until the fish tell you otherwise.
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 | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 7 to 26 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Break off the point (12 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 7 to 26 ft chart-limited; documented 10 to 40 ft | dawn | Break off the point (12 ft) | Small jigging spoon, Marabou jig |
When the water first warms, kokanee slide up into 8 to 26 ft. There's no big seasonal slide here — summer means 8 to 26 ft, winter 7 to 26 ft. If you only fish one area, make it Deep basin: a deep basin around 22 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a dodger + pink/orange squid on downrigger or a kokanee bug + corn rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 26 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (22 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 8 to 26 ft chart-limited; documented 30 to 70 ft | dawn | Deep basin (22 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 3 to 26 ft chart-limited; documented 5 to 40 ft | dawn | Deep basin (22 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 7 to 26 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (22 ft) | Small glow jig + corn or maggot, Tiny spoon |
Spring puts dolly varden in skinny water — 1 to 26 ft is the zone. Summer fish stay in 1 to 26 ft, and winter fish hold in 5 to 26 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for spring dolly varden. Plan around early morning and the evening in the warm months. A small chrome spoon or a baitfish streamer covers the summer program.

Roy Lake is about 26 ft (8 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, kokanee, dolly varden on Roy Lake.
Break off the point is the top-rated area: a drop-off in about 12 ft of water that rates prime for cutthroat trout in summer. Every other rated spot, per species and season, is on the map above.
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.
