The Calderpark Weir and Lade, Lochwinnoch

The Calderpark Weir stands on the River Calder near Lochwinnoch. It once powered the Calderpark, Calderheugh Cottonmills and the later the Calderheugh Cabinet Works. At first a natural volcanic dyke diverted water into a lade and later a substantial stone dam with a sluice was built. The stone dam burst at some point and the lade was abandoned. A new concrete weir with a sluice supplied water when need to a new weir at the factory.
