16-acre lake near Carmarthenshire. The lake tops out around 14 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 16 acres of water rimmed by 0.7 miles of bank. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. 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. The water lies in Carmarthenshire. Closest neighbour on DepthScout: Lower Talley Lake, 0 mi north of here.
Come spring, look for brown trout tight to the bank in 2 to 14 ft. Through summer count on 4 to 14 ft; the winter hold is 2 to 14 ft. If you only fish one area, make it Shoreline break: a drop-off around 6 ft that scores prime in summer. Best bite is after dark and early morning. A spoon at the thermocline or a deep stickbait (night) is the honest summer answer here.
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) |
The spring pattern is a shallow one: european perch in 3 to 12 ft. Midsummer fish sit out in 4 to 14 ft before dropping to 4 to 14 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for european perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small crankbait (perch pattern) gets it done.

| 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 | 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 |
| Winter | 4 to 14 ft chart-limited; documented 12 to 33 ft | midday & dawn | Deep basin (12 ft) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 4 to 14 ft, and winter fish settle into 4 to 14 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.

Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 12 ft.
Upper Talley Lake is about 14 ft (4 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 Upper Talley 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. Open the map above to see every rated 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.
