Important notice about the dangers of swimming in our reservoirs
It's super hot outside and although it's tempting to cool off by taking a dip, we're reminding all our visitors to stay safe by keeping out of the water, across all our visitor sites.
On the surface they can look calm and steady but, underneath, the water is very deep with strong currents. Our reservoirs are purpose built for supplying water
and not for swimming or paddling.
A little about Llyn Clywedog
Majestic views across mid Wales, and a 72m high dam holding back 50,000 megalitres of water, makes this one of our most spectacular visitor sites.
Why was Llyn Clywedog created here?
The creation of the reservoir was driven by the increasing demands on the River Severn as a water source for Birmingham and the English midlands.
How long did it take to build the dam?
Approximately four years to build; work started in 1963 after the passing of an Act of Parliament ordering its construction and finished in 1967.
What is Llyn Clywedog’s role in the water supply network?
It is not linked directly to the water supply network but instead, exists to regulate the flow of water to the River Severn during the winter months, and to ensure a minimum flow during the summer.
