Mellte dam release today

Dwr Cymru Welsh Water usually warn us in advance when they are releasing water from Ystradfellte reservoir, so that we can warn cave and gorge users. Today there was a release that we had not been told about, which caught out a number of groups and could have led to very serious consequences, potentially even fatalities (it seemed to be a more significant release than previous ones). We have asked DCWW to investigate why we had not been alerted in advance (and have also requested that wardens at Cwm Porth alert cavers on-the-day if they themselves are aware of a planned release). We understand that everyone got out safely, but this was clearly an avoidable near-miss. We’ll let you know when we get a response from DCWW…
