Thanks again for responding Billy as I just can't see his posts. But I
did know what he meant about the inlet pipe without having to do a
google. Effectively he'd described how to obtain that drop into the ram
so I knew what he was referring to.

Harry thinks a 'normal person' wouldn't see that as a drop, but I know
that you'd know my background well enough to know that I'm quite normal
in the rural Australian sense but probably not in an urban or American
sense. Having seen so many silly questions online such as can someone
drink rainwater, or drink water collected off a roof or (grasp!!) even
use it on vegetables, I'm always stunned at such lack of awareness of
water and it's provision to house, animals and garden.

Obviously, there has to be some kind of "drop" or the stream wouldn't flow
and it would only be a long, narrow, stagnant pond.

Yes, obviously.

But if it has any kind of flow it's possible to run a pipe upstream and,
if necessary, construct a small "dam" to concentrate the flow into your
ram inlet. The ""dam" would only have to be, say, 6" high!

Yes, but we're revisiting old ground now. If you have another look at the
pics again and think about how far back you'd need to run a pipe to even get
a 6 inch head above a ram if it was perched on the top of the bridge. The
situation Harry mentioned of the ram on the side of the stream might be
possible at a pinch, but I still can't see it as being possible for sitting
on the structure in that sort of irrigation channel.
