(06/01/1997) SX 66577115 to SX 69196964. The Holne Moor Leat formerly used to augment the water supply to the Buckfast Plating Company (Robins 1982, 33) - now feeding the Holne Town Gutter (SX 67 SE 250). This substantial feature remains in use over much of its length is is still maintained. It rises on the O Brook at SX 66477115, N of Horse Ford, and flows for approximately 3km before entering a pipe to flow beneath Venford Reservoir. It reappears at SX 69027085 in a small fenced enclosure and flows SE for a further 1.5km before joining the Holne Town Gutter at SX 69466978. Originally it was carried across the Holne Town Gutter and ran eastwards to join a tributary of the River Mardle from where it was extracted by the Buckfast Plating Company for use in the chrome plating process.
There is no indication as to the origin of this feature though Robins states that the plating company occupies the site of a former corn and woollen mill also supplied by this leat.
This leat bifurcates at SX 66797204, a short branch leaves the main feature to supply Combestone Farm.
