Eigiau Dam Disaster.
On 2 November 1925 the failure of two dams caused a flood that swamped the village of Dolgarrog, killing 16 people. The disaster was started by the failure of the Eigiau Dam, a gravity dam owned by the Aluminium Corporation. The water released from the reservoir flooded downstream,[10] and overtopped the Coedty Dam, an embankment dam. This dam also subsequently failed, releasing the huge volume of water that flooded Dolgarrog.[11] Many more villagers could have been killed had they not been in the local theatre watching a film that night.

The disaster at Dolgarrog led the British parliament to pass the Reservoirs (Safety Provisions) Act in 1930, which introduced laws on the safety of reservoirs. This has since been updated, and the current one is the Reservoirs Act, 1975.
