HER Number:MDV122888
Name:Leat system from the Bledge Brook, Cornwood


A leat channel and a system of feeders, now dry and silted, had its source on Bledge Brook and supplied water to tin streamworks further down the same tributary (MDV27917). The main leat runs approximately north to south and is a substantial example of its type, with an earthwork channel averaging 2.0 metres wide (wider in places) by 0.5 metres and a sizeable bank on its downslope side. Smaller feeders taken from the leat are less well defined and barely visible in places, though may be traced running down the slope towards the tinwork.
