Perhaps a garden escape/throwout, as it's not readily recognisable as a

Canadian pondweed.
http://en.wikipedia.org/wiki/Canadian_Pond_Weed

It goes scraggy when in low light. ie Deep/muddy/green water

You're looking at the wrong plant. I was asking about the
floating/emergent dicot, not the submerged monocot.

I believe that the main waterweed in that pond is Lagarosiphon major
(curly water weed), but I was wondering whether there was a patch of
Elodea nuttallii (Nuttall's waterweed) showing in this photograph, or
whether what can be seen is scraggy Lagarosiphon.
