Have you ever seen a bridge over a fast-running stream where water flows away from the bridge but there's nothing on the other side. It's the riverine equivalent of the one-hand clap.
Have a look at the video and you will see what I mean. This is Job's Mill at Sutton Veny outside Warminster in Wiltshire - a wonderful 17th century house with exceptional grounds and gardens.
This map shows the bridge where the river flows 'out' but not 'in'. And I think it also explains what's happened. It's all about the old mill.
The River Wylye here has two parallel routes. I suspect the one on the right is a mill race - a channel created to take some of the river water to power a water mill. Part of that slipstream has either been culverted or covered over since the mill went out of service to add to the elegance of the garden at Job's Mill. And hey presto, this part of the river comes up for air again underneath the bridge.
But it is a startling scene - one side of the bridge is all grass, and the other is a river, and a lively one, Not a pond but a flowing stream. Fancy that!
