Grwyne Fawr Reservoir 005
The dam and reservoir at Grwyne Fawr in the mountains north west of Abergavenny. The top of the dam wall at just over 1800 ft.
I cannot find a confirmed date, but the reservoir was decomissioned around 2014/5, thought to be due to the concentration levels of some contaminants, considered too high too be able to treat economically.
The dam was completed in early 1928 and the valves were closed on 10 February, with an official opening ceremony on 28 March.
