Clearwater?

Inside the Chennai Port. Those who have been to the world's large ports - Rotterdam, Singapore, Shanghai talk about how dirty the Port of Chennai is. But going back there after over 20 years, I found it cleaner than it was in my memory. 

If a picture like this had been taken in the 1990s, the water would have had a thick coating of oil on it - that would have made the picture more colourful, but I'm sure we'd prefer it this way!
