So the obvious question is what is the difference between the water visible in these two pictures? The sad thing is that they are both the same river and both of the pictures were taken from the same bridge. The fundamental difference is that the upstream reach is an unfenced field, allowing unfettered access by all and sundry, and the downstream stretch is fenced.
