A bendy bridge over a reservoir

By Ffynnoncadno  
Careg Ddu Dam wall in the Elan Valley, providing water for Birmingham. Sometimes called the submerged dam.
The water supply from the Elan Valley goes over 70 miles to Birmingham by a special pipeline called an 'aqueduct'.
It travels all that way 'downhill' by gravity without being pumped, but to do that it has to start from a higher level than the reservoir at the far end.
The water enters the aqueduct through a special valve tower just above this submerged dam. You can see this tower, called 'Foel Tower' beyond the bridge in the photograph.The underwater dam does the job of keeping the Garreg-ddu Reservoir water level high enough to keep the flow going at all times.

We could do with some of that water down here. Cracking shot, though, with its s-curve bridge and powerful sky.

I've been back to this a couple of times, this time with an award for the composition and for the menacing sky
