Further to how murky rivers in the UK can be, this satellite photo was from the time of the snow a couple of weeks ago, you can't see the Thames for cloud unfortunately, but look how far the brown extends out to sea from the river in the south west. If the mud from the Thames extends a third as far, then you'll never see blue water in London.

Hehe!

If I'm not mistaken, the colour of water is affected by the position of the sun in relation to the camera - if one is taking the pic facing the sun, the water will appear brown - if the sun is behind you, it will appear blue. That's "more brown" and "more blue"!!
I'm nowhere near water now to test this out (it's also nightime here in South Africa at the moment).
Anyone else hear that explanation? - I recall my father (a keen photographer in his day) telling me this.

This is irrelevant to the opacity of the water, as in KG26_Alpha's photo by the steps, you will see nothing down through it. The sea at Dover would probably be a very different matter, but the Thames in London will be opaque.

Pictures of the same beach at Brighton (South coast of England).
Taken with sun behind and in front of the camera, same result as far as I can see .

the colors depending of camera matrix (film) and physics of light rays going in and out of water.
Color in reality and fixed by camera are always different. No one photo without corrections with speciall rules show real colors when you make a picture of water on a big space.
