History

Late C18 staircase of sandstone weirs built in steps below the Swansea Canal in order to take surplus water from the canal to the River Tawe after periods of rain and during periods of canal drainage. The surplus canal water from the overflow and outlet was used in C19 for power for the Pheasant Bush tinplate works.

At the top of the weirs, adjoining the tow path on the SE side is a 2-bay primary overflow chamber, said to be partly timber-lined with connecting ground sluice with working paddle gear to the north. Since 1979 this area has been partially covered and C20 control machinery inserted. The secondary overflow above the weir remains
