The Dour has had an industrial use since at least
AD 762, when the first written record of a Dover corn
mill was made. This mill, probably at
Buckland,
was also the first recorded mill in Britain. Over
the years the Dour has supplied the energy for thirteen
watermills, of which eight were
corn
mills, the others producing
paper.
The river has been a source of power or water for
other industries, including iron foundries, saw mills
and a tannery.
