13-acre lake near Carmarthenshire. The lake tops out around 6 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. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 13 acres wrapped in 0.6 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Carmarthenshire claims this one. If the bite dies, Upper Talley Lake is 12 mi to the north.
In spring, brown trout run shallow here, mostly 1 to 6 ft. Summer keeps them at 2 to 6 ft, and they winter in 1 to 6 ft.

You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
