Why was Lake Vyrnwy created here?
Lake Vyrnwy was created to capture water from the River Vyrnwy so it could be used to supply the ever expanding city of Liverpool with fresh clean drinking water.
What was here before?
Well, a century ago the Vyrnwy Valley looked very different. The valley of the River Vyrnwy was closed off by the building of the dam and the whole valley was flooded when
the reservoir was filled. The creation of the lake involved relocating the former village of Llanwddyn. Farms and their land were also submerged below the water.
The village consisted ofa ParishChurch, two Chapels, three Inns, ten Farmhouses and 37 houses. In dry summers the water level sometimes drops far enough for the
ruins of the old village to be seen - kind of eerie but cool huh?
The new settlement was built lower down the valley, even the graveyard was relocated along with the Church.
How long did it take to build the Dam?
The Corporation of Liverpool began work on the huge masonry dam in 1881 to secure a fresh water supply for Liverpool. The Dam was completed in 1888.The lake took two
years to fill andwater was first supplied to Liverpool in 1891. An official ceremony in1910 was conducted by the then HRH the Prince of Wales to mark the completion of the works.
How big and deep is it?
The reservoir is 216 ft deep at its maximum depth. The pointed tower is the ‘straining tower’ and is where the water leaves the lake on the start of its 70 mile journey down the aqueduct. The water passes through a fine metal mesh to remove large objects. Lake Vyrnwy is surrounded by a perimeter road which is 11.75 miles long.
What is Lake Vyrnwy’s role in the water supply network?
The reservoir was created to provide drinking water for Liverpool. The water is carried to the City of Liverpool by an Aqueduct. The dam and reservoir were created when
Liverpool was growing rapidly. The new factories and mills of the Industrial Revolution were attracting workers to the area. Clean water was required not only for the increased population, but for steam driven machines.
Where does the water come from?
The dam and reservoir was built to take advantage of the nearby Vyrnwy Valley and The River Vyrnwy. The reservoir was filled by restricting the flow of the river behind the Dam.
The two stone towers on the top of the dam house the valves which control the excess water flowing from the base of the wall to allow the river to flow normally.
In partnership with the RSPB, Lake Vyrnwy provides facilities for school groups to learn about this special environment we are caring for.
