Ten years after the creation of Eryri (Snowdonia) National Park, construction began on Llyn Celyn reservoir. The reservoir was built for a number of reasons, one of which was to supply drinking water to the Chester to Liverpool area. Its creation involved the
damming of the River Tryweryn
resulting in the flooding of Capel Celyn and adjacent farmland. The village was a strong-hold of Welsh culture and language and, with the reservoir appearing to provide no immediate benefit to the local community, the move was
strongly opposed
by inhabitants of Capel Celyn. In
1965 the village was flooded
and Llyn Celyn was created, covering more than 770 acres and destroying 12 farms. The reservoir is up to 43 metres deep and can hold up to
71,200 mega litres of water; this would take 91 days to empty on a constant 9 cumec release. In October 2005 Liverpool County Council issued a
formal apology
for the flooding of the village, which was met with mixed responses from the people involved.
