Leat & Dam at Llanmihangel Mill is a post-medieval water management structure located in Wales, designated as a Scheduled Ancient Monument under Cadw reference GM449. The leat and dam represent the engineering infrastructure developed to supply water power to the mill, reflecting the industrial importance of water-driven milling in the post-medieval and modern periods. Such structures were essential to the operation of mills across Wales, channelling water from higher ground to create the hydraulic head necessary to turn mill wheels. The surviving physical remains demonstrate the practical application of medieval and early modern water engineering principles adapted for sustained commercial use through the post-medieval era.
