Fishing Llynnau Barlwyd: what the data says
5-acre lake near Gwynedd. The lake tops out around 10 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here is how the season plays out for each species, straight from the data behind the map.
Llynnau Barlwyd maps at 5 acres behind 0.3 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end.
Brown Trout fishing at Llynnau Barlwyd
Spring puts brown trout in skinny water — 1 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 1 to 10 ft. Shoreline break is the standout, a drop-off at roughly 5 ft, rated prime for summer brown trout. Plan around after dark and early morning in the warm months. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 10 ft | dawn & dusk | Shoreline break (5 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 3 to 10 ft | night & dawn | Shoreline break (5 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 10 ft | dusk & dawn | Shoreline break (5 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 10 ft | dawn | Shoreline break (5 ft) | Jigging spoon, Small stickbait (slow) |
European Perch fishing at Llynnau Barlwyd
Early season european perch use the shallows, holding in 3 to 10 ft. Even in summer they hold at 3 to 10 ft; winter keeps them in 3 to 10 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small crankbait (perch pattern) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |

Northern Pike fishing at Llynnau Barlwyd
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 3 to 10 ft in summer and finish the year down in 3 to 10 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| 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) |
