Here's an alternative view of the lock-keeper's cottage featured in my main 365 post for today... especially for those who prefer colour! It also shows the reservoir high water line quite clearly.
@trinda In the last 10 days apparently Trinda - the silt is very rich in nutrients so air-borne seeds germinate and grow quickly. In a month the whole valley will be green which will detract from its stark beauty - I consider myself lucky to have seen it now. Immediately after it was drained it was too dangerous to visit because of the soft deep mud.
@dibzgreasley At the deepest point of the valley the waterline is 40 metres above the floor so, yes, a lot of water - 51,000,000 cubic metres or 11,220,000,000 gallons! A lot of water cascades through the barrage each day and gegerates electricity - during the night when there is a surplus of electricity on the grid, this water is pumped back up to the reservoir. During the draining period the water was not pumped back up and was allowed to run out to the sea so the reservoir drained over the space of five or six weeks and at a time when the reservoir level normally drops due to the reduced flow of the river Blavet in Spring and Summer.
This has been a most interesting series. A unique view to something we do not often see...the landscape under water. Someone else mentioned in another image, but I'm also intrigued how the structure broke down into triangles.
