25-acre lake near Carmarthenshire. The lake tops out around 14 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 25 acres wrapped in 0.8 miles of bank. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. Carmarthenshire claims this one. Upper Talley Lake sits 0 mi south — the closest neighbouring chart.
Start shallow in spring: brown trout sit in 2 to 14 ft that time of year. They don't go far with the seasons — 4 to 14 ft covers summer, 2 to 14 ft covers winter. The spot to know is Shoreline break, a drop-off in about 6 ft of water that rates prime for brown trout in summer. Warm-month bites cluster around after dark and early morning. Throw a spoon at the thermocline or a deep stickbait (night) 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 | 2 to 14 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Shoreline break (6 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 4 to 14 ft chart-limited; documented 25 to 60 ft | night & dawn | Shoreline break (6 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 2 to 14 ft chart-limited; documented 5 to 30 ft | dusk & dawn | Shoreline break (6 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 2 to 14 ft chart-limited; documented 5 to 35 ft | dawn | Shoreline break (6 ft) | Jigging spoon, Small stickbait (slow) |
When the water first warms, european perch slide up into 3 to 12 ft. By summer they slide out to 4 to 14 ft, and by winter most fish are in 4 to 14 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small crankbait (perch pattern) rigged through the warm months.

| Summer | 4 to 14 ft chart-limited; documented 8 to 28 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 4 to 14 ft chart-limited; documented 10 to 33 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Drop-shot on deep flats |
