URPoint Details
Ffynnon Llugwy (English: Llugwy spring) is a lake in the Carneddau Range of mountains in Snowdonia.
It lies at a height of about 1,786 feet (544 m) and covers an area of some 40 acres (16.19 ha). It has a maximum depth of 146 ft (45 m).[1]
Since the early 20th 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
The Afon Llugwy flows via Capel Curig and Betws-y-coed before becoming a tributary of the River Conwy.
