Thanks. I'd better point out again (I did in my first post of this WIP,
but not in this one) that the trees in the bg are a photo. It's cheating
really and I'd hope to model them in any final post. The water is

    texture {
        pigment { rgbt 1.0 }
        normal {
            bumps 0.008
            scale 0.16
            // turbulence 0.5
        }
        finish {
            ambient 0.0
            diffuse 0.0
            reflection {
                0.5, 1.0
                fresnel on
            }
            specular 0.4
            roughness 0.003
        }
    }
    interior {
        ior 1.3
    }

with a black plane underneath it

anti-aliasing is probably the main reason why it took
Time For Parse:    0 hours  8 minutes  27.0 seconds (507 seconds)
Time For Trace:   81 hours 47 minutes  26.0 seconds (294274 seconds)
    Total Time:   81 hours 53 minutes   1.0 seconds (294781 seconds)

I'll have a look at raising the water level, it's keyed to the texture
and the hf of the far (and near) banks however.
I'm working from a reference photo, the trees are pretty much in keeping
with that.

Thanks, It's slow going though :-)
