Cutlers (grinding) wheel built in 1723 - present weir built in 1723. By 1794 much enlarged to 52 troughs and a tilt hammer. Steam power supplementing water on this site by 1864. By 1897 water power still providing motive power for 3 tilt hammers. Water power still in use in 1907 but disused by 1936. (all info from SMR PRN 1687 backup file quoting Crossley et al, 1989 and Miller, 1949). Map evidence shows that by 1905 the narrow mill dam shown on earlier plans was covered over and by the 1930s the works now called Clifton Works was reaching its present size and appearance. Change and addition to the works appears to have been on a piecemeal fashion since at least the mid 19th century with Victorian ranges retained along the river frontage. The water running through the works culvert discharges just downstream of Hillfoot Bridge. (Crossley records a brick culvert visible in 1989)
