Modern mill leat.


The Ordnance Survey 1:2500 First Edition mapping of 1867-8 depicts a water mill, annotated as 'Mwillin y Chorrin (Corn)'.


Waterpower for the mill was drawn off the River Glass by a weir, from which a leat, controlled by a sluice, led 260m to the mill.


The earthwork banks of the leat are still visible.


The grid reference marks the midpoint of the course of the leat, for indicative purposes.
