79-acre lake in British Columbia. The lake tops out around 21 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Urn Lake runs 79 acres with 1.4 miles of edge. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 76% of this chart, as modeled. Tip to tip the water measures near 0.4 mi with a 0.3-mi widest point. The water lies in Fraser-Fort George Regional District. Closest neighbour on DepthScout: Lamb Lake, 4 mi west of here.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 6 to 21 ft before dropping to 4 to 21 ft for winter. The spot to know is Break off the point, a drop-off in about 9 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
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 | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 6 to 21 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (9 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 21 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 21 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (9 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: kokanee sit in 6 to 21 ft that time of year. They don't go far with the seasons — 6 to 21 ft covers summer, 5 to 21 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 18 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a dodger + pink/orange squid on downrigger or a kokanee bug + corn until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 21 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (18 ft) | Small dodger + squid (pink), Wedding-ring spinner + corn |
| Summer | 6 to 21 ft chart-limited; documented 30 to 70 ft | dawn | Deep basin (18 ft) | Dodger + pink/orange squid on downrigger, Kokanee bug + corn |
| Fall | 3 to 21 ft chart-limited; documented 5 to 40 ft | dawn | Deep basin (18 ft) | Dodger + squid (deeper red/purple), Small spoon |
| Winter | 5 to 21 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (18 ft) | Small glow jig + corn or maggot, Tiny spoon |
When the water first warms, lake whitefish slide up into 6 to 21 ft. There's no big seasonal slide here — summer means 6 to 21 ft, winter 6 to 21 ft. If you only fish one area, make it Deep basin: a deep basin around 18 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 21 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (9 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 6 to 21 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (18 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 6 to 21 ft chart-limited; documented 8 to 30 ft | dusk | Break off the point (9 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 6 to 21 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (18 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: burbot sit in 6 to 21 ft that time of year. They don't go far with the seasons — 6 to 21 ft covers summer, 5 to 21 ft covers winter. The spot to know is Deep basin, a deep basin in about 18 ft of water that rates prime for burbot in spring. Warm-month bites cluster around after dark and midday. Throw a heavy jig + cut bait until the fish tell you otherwise.

| Summer | 6 to 21 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (18 ft) | Heavy jig + cut bait |

| Winter | 5 to 21 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (18 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Urn Lake carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 18 ft down.
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 Urn Lake specifically, so confirm the current rules before you fish.

Urn Lake is about 21 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 rainbow trout, kokanee, lake whitefish, burbot on Urn 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.
Deep basin is the top-rated area: a deep basin in about 18 ft of water that rates prime for kokanee in spring. Open the map above to see every rated spot for each 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.
Fishing on Urn Lake is regulated by the BC freshwater fishing synopsis. Check the official British Columbia regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
