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. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 5 acres wrapped in 0.3 miles of bank. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. It sits in Conwy. Llyn Edno sits 3 mi west — the closest neighbouring chart.
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.
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 | 1 to 10 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Shoreline break (5 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 3 to 10 ft chart-limited; documented 25 to 60 ft | night & dawn | Shoreline break (5 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 10 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Shoreline break (5 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 1 to 10 ft chart-limited; documented 5 to 35 ft | dawn | Shoreline break (5 ft) | Jigging spoon, Small stickbait (slow) |
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 chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 3 to 10 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 3 to 10 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (9 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 3 to 10 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + maggots, Small balance jig |
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.

3 pieces of structure are mapped here — Deep basin, around 9 ft, is the deepest of them.
Llynnau Barlwyd is about 10 ft (3 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 Llynnau Barlwyd. 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. Scroll up to the map for the complete spot list by 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.
