here's a water surface i was happy with. it's produced with a heightfield
using these pigments. It's probably to "noisy" for something like Bill
Hails tranquill scene, though. 

in the image itself, i used a "pigment { rgbt <1, 1, 1, .97> }", and a
"finish { specular .2 roughness .1 reflection .3}" to texture the
heightfield. Photons were also used. 

it was going to be a scene of a "water moving facility" with down-trodden
slaves doing nothing but endlessly pushing water through for no apparent
reason. but i digress. it wouldnt be hard to smooth this out a little to
make it less "active" so to speak. 

#declare wrink = pigment {
  wrinkles 
  color_map {
    [0.0 rgb 1]
    [0.3 rgb .8]
    [0.6 rgb .4]
    [0.9 rgb .1]
    [1.0 rgb .8]
  }
}  

#declare rip = pigment {
  ripples 
  color_map {
    [0.0 rgb 1]
    [0.3 rgb .8]
    [0.6 rgb .4]
    [0.9 rgb .1]
    [1.0 rgb .8]    
  }
}          

plane {
  <0, 0, 1>, 10
  pigment {
    average 
    pigment_map {
      [1.0 wrink scale <1, 1.5, 1>]
      [0.8 rip scale <2, 2.5, 1>*.6 translate <-15, -3, 1>]
    }
  }
}

Your description reminds me of the fictional Pacific island (based on 
Sri Lanka) that was described in Arthur C. Clarke's book The Fountains 
of Paradise. The local king/warlord had a bunch of pleasure gardens 
built, along with some large fountains fed from a cistern on a mountain. 
To keep the fountains going, he had hundreds of slaves continually 
carrying water up to the cistern.

Interesting :) I've heard of the book, but never knew what it was about. For
this scene, i got stuck on the waterfall part that was supposed to be at
the near end, but isn't. I thought about doing tiny blobs, but how to do a
nice "fade" between the top surface heightfield and the droplets, i don't
know. H.E. Day had an amazing waterfall a few years back... maybe it's time
to search to see if he posted code.

I see what you mean about averaging, it works really well.

King Kalidasa of Taprobane. By a strange coincidence I just finished
reading that a while back :-)

It reminds me of jello or something solid more than water for some reason.

Well, that's just part of the setting...the book is called "The 
Fountains of Paradise", but it isn't about the fountains...not water 
ones, anyway. It's really a surprisingly accurate story about a guy 
trying to build a space elevator...it starts off with him demonstrating 
a remarkably strong new material composed of of long chain molecules of 
carbon.

Make a fountain instead? ;-)
