This is an artificial lake in the centre of Brittany where my brother has a holiday home which we all visit en masse every September for larks!!! At an elevation of 121m it has a surface area of 4km and it is the largest artificial lake in Brittany. It was created to power the dam of Guerledan and construction took seven years from 1923. The creation of the lake and the dam cut through the Nantes-Brest canal and seventeen of the old locks were submerged. Beginning in 1951 the dam was drained every ten years revealing a hidden landscape of submerged locks and buildings but modern technology has rendered this draining unnecessary although there is talk of this draining taking place again in the next two years.
Gotcha on that Geoff... looks a very nice place and area to visit../..I suppose the draining would be to clear out the sludge.. ?...Dj.
Yeah, Dave, apparently they drain it for "maintenance" whatever form that takes and the the city that lies beneath the lake , formerly known as Ys, is revealed! However, according to Wikipedia Ys is a mythical city along the lines of Atlantis so I'm none the wiser as to what lies beneath the lake. We'll have to time one of our visits when all this is taking place!!! Incidentally off to Madeira Monday 8th!!!Cheers, GL.
