Maybe it is a stupid question: How can i make a lake like this: http://www.dolomitibellunesi.com/2014/04/23/lago-di-sorapiss-3/ it's needed only to setup the tint decay and the volume colo in the water shader? or must be applied also a color to the bottom of the lake?
Thank you for the attention.

Since the water is murky and has reduced reflective properties because of that you can get away with simply adding a surface layer in between the water shader and lake object.
Set the colour to RGB 0,186,186 and reduce the coverage of the layer to 0.4.
That should already give a nice start.
Thank you @Tangled-Universe, i supposed that there was some secret trick behind. I will try it as soon as my pc will finish a rendering. I want my alpine lake! :)
