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.

Brilliantly rocky, technical and wild. Just make sure you carry spares and tools with you.

can be very wet and bogy at the start

A brilliant bit of rocky single track running along llyn cowlyd hard to get to but worth the time

Ffynnon Llugwy lies at a height of about 1,786 feet (544 m) and covers an area of some 40 acres and has a maximum depth of 146 ft (45 m). Since the early twentieth century water has been taken from its outflow, Afon Llugwy to feed Llyn Cowlyd via a series of leats. Since the mid 1970s the lake has additionally acted as a reservoir for Bangor and eastern Anglesey, which necessitated the laying of an 11-mile pipeline to the water treatment works at Mynydd Llandegai. Afon Llugwy which flows via Capel Curig and Betws-y-coed before becoming a tributary of the River Conwy.

Penrhyn Quarry was the largest slate quarry in the world by the end of the 19th century. In its prime, it employed nearly 3,000 men who toiled in tunnels that reached a mile (1.6 km) into the hillside and delved 1,200 feet (370 m) deep. The Great Penrhyn Quarry Strike of 1900 to 1903 was one of the most notable industrial strikes in history. The culmination of several years of anger at the conditions endured by workers, it was a battle that changed the community in this part of North Wales forever. Today, the quarry is still operational and employs a few hundred people. It is also home to Velocity 2, the fastest zipline in the world, which flies an incredible 1,640 feet (500 m) above the quarry lake.

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.
