Popular around Coed Dolgarrog National Nature Reserve
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.

The pipes are directly linked to the legacy of the tragic Dolgarrog Dam Disaster. In November 1925, the failure of the Eigiau Dam, followed by the overtopping and failure of the Coedty Dam, caused a devastating flood that swamped the village, killing 16 people. This disaster led to the passing of the Reservoirs (Safety Provisions) Act in 1930, which introduced crucial laws on reservoir safety. While the pipes themselves weren't the cause, they are an integral part of the hydro-electric system that was at the heart of the disaster.

The Dolgarrog pipes are a prominent and historically significant feature in the landscape around the village of Dolgarrog in the Conwy Valley, North Wales. They are part of a hydro-electric power scheme that has been in operation for over a century. These large pipes carry water from the Carneddau mountains to the Dolgarrog hydro-electric power station, which was originally built to provide cheap electricity for an aluminium smelting plant established in 1906. While the aluminium factory has since closed, the power station continues to feed electricity into the National Grid.

The sobering part was reading how they thought it was safe after hearing the church bells. They weren't, it was the church getting swept away!!!!

The worst part of any hike ever. I had to carry on going up, creating my own path, through trees, scrambling up mudfalls, rock climbing with no ropes. it's all collapsed.
