The monument comprises a stretch of aqueduct forming part of the Big Cut.

This stretch is up to 10m wide. Its length is approximately 2500m and extends from N of Kerrycroy Farm in a WNW direction to a point W of Kerrycrusach Farm.

The proposed scheduling includes all the aqueduct in water and an area on either side in which traces of activities associated with its construction and use may survive, with a width of 15m and a total length of very approximately 2500m, extending over an extremely sinuous course from the N side of the road leading to Kerrycrusach to a point at the end of a side road 175m N of Kerrycroy, as marked in red on the accompanying map extract.

Statement of Scheduling

The monument is of national importance because it forms part of a series of aqueducts, or water-cuts, designed by the distinguished Scots engineer, Robert Thom. He died, and was buired, in Rothesay. The aqueducts and dam were constructed between 1811 and 1822 to provide a workable water-supply to Thom's cotton mills in Rothesay, and the ingenius way in which he wrung every last drop of water from off the landscape of central Bute is physically demonstrated by these remains and a lasting testimony to one of Scotland's notable engineers and inventors.
