Devonport Leat is one of the best examples of Dartmoor leats. It was built in the 1790's to channel water to the booming docks of Devonport in Plymouth, although now it terminates at Burrator reservoir. It is fed by the West Dart, Cowsic and Blackbrook rivers and its head is just north of Wistman's Wood.
It has many interesting features - aqueducts, a tunnel and even a waterfall as it descends into the Meavy river at Raddick Hill. Considerable engineering skill was involved in building it.
