24-acre lake near Powys. The lake tops out around 26 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Llan Bwch-llyn Lake draws 24 acres inside 0.9 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. About 71% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 0.3 mi long by 0.2 mi wide at the broadest reach. The water lies in Powys. Closest neighbour on DepthScout: Llangorse Lake, 12 mi south of here.
When the water first warms, brown trout slide up into 3 to 25 ft. Summer is an 8 to 26 ft game here, winter a 4 to 26 ft one. Start at Break off the point. It's a drop-off holding about 12 ft of water and rates prime come summer. The feeding windows run after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) 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) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 8 to 26 ft chart-limited; documented 25 to 60 ft | night & dawn | Break off the point (12 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 4 to 26 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 26 ft chart-limited; documented 5 to 35 ft | dawn | Break off the point (12 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: european perch sit in 3 to 12 ft that time of year. Warm water sends them out to 7 to 26 ft; cold water stacks them in 8 to 26 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small crankbait (perch pattern) 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 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 7 to 26 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (22 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 8 to 26 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (22 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 8 to 26 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (22 ft) | Tungsten jig + maggots, Small balance jig |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (12 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (12 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
The chart marks 4 structure features on Llan Bwch-llyn Lake; the deepest is Deep basin at about 22 ft.
Llan Bwch-llyn 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 brown trout, european perch, northern pike on Llan Bwch-llyn 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.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for european perch in spring. The interactive chart above rates every spot for each species and season.
For brown trout, the summer bite is best in after dark and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
