I used to live in lower Ems valley, the one in Sussex, and it was
infested with watermills. The gradient was very shallow and so to
maintain the headwater for each mill there was a rather convoluted
array of leats often by-passing mills lower down the valley to give
greater headwater to others. Very confusing!
