Overview
Tonnes of water and debris descended on Dolgarrog, Conwy, 2/11/25, when the Coety Reservoir burst following the collapse of part of the Llyn Eigiau dam. 16 people were killed. Such was the interest in the disaster that police had to erect a roadblock to keep back crowds obstructing relief operations. This footage of the aftermath was shot by a Colwyn Bay cinema operator, Frank H Kenyon, who also worked as a ‘stringer’, supplying footage of local events to a newsreel company.
