Three people, Castle Mill owner William Hutchison, dyer William Stillie and Isabella Miller, a young factory worker, were swept away when the bridge on which they were standing collapsed into the flood waters. The collapse was probably due to the impact of water-borne debris upon the embankment on which the foundation of the bridge stood. Both William Hutchison and Isabella Miller perished in the torrent, however William Stillie was rescued further downstream. Despite exhaustive searches, Isabella Miller's body was not recovered for several days. It was eventually discovered at Glenfoot, where the burn joins the River Devon.
