It is not the 80 years Prasanth - there are older dams all over the world - but the material and construction do surprise me. Nice shot from a good angle.
I wrote quite a long commentary, Prashanth, but somehow manged to lose it. Basically I said that the shot was very good and suggested "Snapshooter86" as a very knowledgeable photographer who knows how to write a constructive critique. Most of us here on Caedes are amateurs with varying degrees of skill. I agree with Tigs about trying a click of negative gamma. I would also try a half click of positive color saturation. I'd give this a 6.5 out of 10 because it lacks that illusive "Wow" factor.
It must have a really fine construction to have held up this long. It always looks hot and hazy to me in these photos. I expect you are used to it though. I am glad that you don't over process your images. The colors are really nice here.
