Talking about rivers - I know one beautiful
Robbie Rivera track called
Float Away, it's sung by Justine Suissa, the famous "trance voice", and words go something like this: 'I wanna to take you down by the river, where you can watch me undress, float away, float away'
It was quite much played about half year ago (at least in my country). It's not techno, but take a listen anyway.
Float Away (NF Project radio mix):
