Rising Cave
Access As the cave has been used as a water supply by the Brecon Carreg Water Bottling company they do not officially give permission to visit the site.
Description An extensive dry series opens on to 4 river chambers, which are part of the underground course of the River Loughour. Beyond the 4th River Chamber, about 125 metres of submerged passage has been explored by divers, ending in a low bedding plane.
History The cave has a long history, with explorations recorded since 1841, and an inscription reported from 1835.
Hydrology Tested from Ogof Foel Fawr. 'water becomes turbid after heavy rains...flow 63 tons per minute, which is equivalent to 14,112 gallons per minute [1.069 cumec]'(Cantrill, 1907). Minimum yield 4mgd [0.146 cumec] (1959)
Mineral water has also been extracted not from the cave but from the nearby Llwyndewi borehole
