It contains 900,000 cubic metres (200,000,000 imp gal) of water received from the Elan Valley Reservoirs,[3] 117 km (73 mi) away, in Wales, which arrives via the Elan aqueduct, by the power of gravity alone, dropping 52 metres (171 ft) – an average gradient of 1 in 2,300.

Before 1987 it was leaking 540 litres (120 imp gal) per second. In that year ground-penetrating radar was used successfully to isolate the leaks.[3]
