Firstly let me say a big THANK YOU to Vivienne at BugWomanLondon, David at White-Rainbows and Brian at blhphotoblog for taking the time to reply to my Damsel/Dragonfly quiz. I don’t know the correct answers, so all I can say is, you’re all winners! 😊
The road up to the Grande Dixence dam is now open. So yesterday I thought I’d take a drive up there, to walk along the track which runs by the side of the reservoir. Everything was going well until I came across a huge patch of snow, (see pic 21), which was probably the result of an avalanche during the winter. So I turned about and headed up to the Gentiane hut, which was closed and completely deserted.
The reservoir is one of a 1000 in Switzerland and ‘Lac des Dix’ is the largest lake over 2,000m in the Alps. As I’m sure many of you will already know, (since I’ve posted this a few times now 😉) at 285m or 935ft, it’s also the tallest gravity dam in the world. (It’s the 5th tallest in the world and the tallest in Europe). The dam itself is 700m or 3,000 ft wide and contains around 6 million cubic metres of concrete. It holds up to 400 million cubic metres of water, but it was only just over half full yesterday. It’s fed by 4 smaller reservoirs in the neighbouring valleys, including Ferpècle and Zermatt, via around 100km or 62 miles of tunnels. The level of water gradually rises throughout the year in preparation for the huge increase in electricity usage during the cold winters.
My walk started in sunshine, but the clouds soon came over, so it wasn’t a great day for photography. If you’d like to see some impressive aerial shots and to find out more fascinating facts about the dam, please click here.
