Oh dear we’ve been very lax in updating the blog recently. Too busy enjoying ourselves. For the last two weekends we’ve been spending time in the Elan Valley camping overnight in a wood near Rhayader in mid Wales and photographing and walking round the lakes during the day. We were there to take advantage of the amazing Autumn colours and as you can see from the photographs this was enhanced by the amazingly still water.
The dams, reservoirs and 73 mile of aqueduct of the Elan Valley waterworks in mid Wales were mostly built about a hundred years ago to supply clean water to the city of Birmingham in the English Midlands. Although it looks like a bridge the Carreg-ddu dam (below) is partially submerged to keep the water level up at the extraction point.
Leaving aside the morality of removing the original residents to flood the valley the reservoirs and dams which supply water to Birmingham entirely by gravity are a an amazing feat of engineering. It is almost beyond comprehension that thousands of men could build these structures. It really does put in perspective the rubbish that we see built today. In addition the foresight of elders of Birmingham to conceive and undertake such a scheme is astonishing. As well as building the dams this also involved building a 73 mile long aqueduct down which the water travels at less than 2 miles per hour, taking one and a half days to get to Birmingham.
There is more information on the Elan valley dams here.
The walk around Carreg-Ddu reservoir is a lovely walk and you can start at various points. We parked at the car park by the Carreg-Ddu dam and did a complete circuit of the lake. The map below shows a longer walk starting at the visitor centre.
