This dam was constructed to provide power for the Pont-y-saeson Forge which was about 500m below it. Little is known about this forge which may have begun functioning as early as 1675, but the dam is probably at least C18 in origin.


The dam is constructed of rubble sandstone walling. The upstream side has eight low arches with elliptical heads for the sluices. The downstream side has the spillways from these with an over-spill or fish ladder to the right. The dam provides a 3.5m head of water in its current state. The dam is about 20m long and about 2.5m wide. The crest of the dam has been rebuilt in the late C20 as a part of its current role as a fishing lake.

Reasons for Listing

Included as a well preserved small mill dam dating possibly from the C18, and as a part of an important group of surviving relics of the metal industry in the Anghidy valley.
