I am reading a book about Devon villages - it frequently mentions that there is a leat running through the village.
A leat (also lete or leet) is the name, common in the south and west of England, for a watercourse (natural, or more usually, artficial) or aqueduct, supplying water to a watermill or its mill pond. Leats may also deliver water for mineral washing and concentration, for irrigation, or to a dye or other industrial works.
This is a picture of the Devonport Leat crossing the River Meavy, courtesy of Michael A. Parle.
