In a spell of dry weather in the summer of 2014 the flow of the Locher Water (between Kilbarchan and Bridge of Weir) was reduced to a trickle. This revealed the footings of what appeared to have been an old weir or dam with the timbers preserved by decades of immersion in water. The weir or dam, constructed in the early 1860s, was associated with Locherfield Bleach Works which was owned by Hardie, Starke & Co. Forum members have been investigating the site and its history.
This field survey into the remains of the bleach works is continuing and a second weir has been revealed on the bank of the river further downstream where a large spill tunnel exits into the river.
