Llyn Brianne: Opened in May 1973
The roadways were widened and heavy construction plant trundled through daily. Strangers with a variety of accents moved into lodgings and rented houses in the village and in the surrounding area.
Llandovery was awash with engineers and construction workers. Local businesses did very well and within a very short time village life had changed completely. Others couldn’t wait for normality to return. Every day convoys of large lorries headed up one side of the valley and back down the other, hauling anything and everything to the site. Bus loads of people came to see the worksite of the largest dam of its type in Europe.
On the 15th May 1973 the dam was officially inaugurated by Princess Alexandra.
