HER Number:MDV80536
Name:Huckworthy Mill Leat


Huckworthy Mill Leat running from SX53867132 to Huckworthy Mill at SX53177053. A documentary source indicated this leat may date to the late 16th century, making it one of the oldest leats on Dartmoor, but this has not been confirmed. This may indicate a possible earlier date for the mill site also. First depicted on the mid 19th century Tithe map. Surveyed and recorded in the Dartmoor Trust Leats Project.

Full description

Morley Estate, 1578, Licence to construct and maintain a weir, PWDRO 69/M/2/581 (Record Office Collection). SDV349977.

Plymouth and West Devon Record Office hold a source dating the leat to the late 16th century. This source is a licence dated 30 November 1578 to Jerome Mayhowe of Boringdon, esquire and Nicholas Slanning of Bickleigh, esquire ‘to construct and maintain a weir at Byklym Wood alias Buckym Wood (Bicklime Wood) in the water called the Walkham, for his mill at Hokeford Bridge (Huckworthy)’.
The National Archives website summary of this source appears definitive however, the original source is rather more tenuous and suggests the original leat may have been to the west of the river.

1840, Tithe Map (Cartographic). SDV339770.

Leat is depicted on the Tithe Map.
