Low water

Hydroelectricity is produced by hydropower, and most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. Djupdal Kraftverk, you can see the dam in "the end of the river" at the picture, is an hydroelectric installation located at Djupdal in Rollag.

This week they had to open the dam, and let the water in the reservoir fall. This is a very unusual view! Ashore there are traces which show the normal height of the water. Later, when the height is back to normal, I will show you a picture of that too. :o)

My brother took this picture with his cellphone yesterday.
