Modern watermill and associated water management.


The Ordnance Survey 1:2500 First Edition mapping of 1868 indicated that a waterwheel was incorporated within the farm buildings at Ronaldsway farm.


The millpond was fed by a natural watercourse flowing from the north from the direction of Ballahick. The pond covered an area of 0.6 acres, and was dammed by a substantial embankment on the south and west sides. The millpond was connected to the mill by a 400m leat. The leat had similarly to be embanked for three quarters of its length.


The tail race led under the road and into the sea which is immedately to the east of the farm complex. The leat and dam have been infilled and now lie within the Isle of Man Airport estate, though can still be traced as cropmarks.
