Modern overflow race.


The Ordnance Survey 1:2500 First Edition mapping of 1869 shows a group of buildings together with the annotation, 'Corn Mill'.


The mill stands just a few metres to the south of the river, which has an extensive catchment derived from the hills inland of Kirk Michael.


The watersupply was derived from a long leat, which was cut into the south side of the winding, narrow valley and extends some 500m upstream, where the inlet was controlled by a sluice and weir. The overall fall on the leat is between 10-12m.


A short 12m overflow race, located 70m upstream, protects the mill complex and was governed by a sluice, which is annotated on the OS (to which the grid reference relates).


The overflow race is still extant.
