    Tips

    June 11, 2025

    The reservoir was originally built in 1924 to supply water for the hydro-electric power station in Dolgarrog, which in turn powered an aluminium smelting works. This power station is still operational today.
    Coedty Reservoir is historically significant due to its involvement in the devastating Dolgarrog Dam Disaster of 1925. The failure of the Llyn Eigiau dam, located upstream, led to a surge of water that also breached the Coedty dam. This resulted in a catastrophic flood that swept through the village of Dolgarrog, causing the loss of 16 lives.
    Coedty dam is a "balance tip" dam, meaning water flows from it automatically when it reaches high levels. This excess water flows into a spectacular gorge below, which is used by outdoor pursuit groups. However, gorge walking here can be dangerous due to the sudden releases of water.
