This cache is situated near the Raddick Hill Sluice Gate on the Devonport Leat.
Devonport Leat is a considerable engineering achievement. It was built in the 1790's to take fresh water to the ever growing docks of Devonport in Plymouth, but now it terminates at Burrator reservoir. The water is taken from the West Dart River and the Cowsic, north of Two Bridges. Only the Dartmoor section of the leat survives due to building and modernization within the city of Plymouth.
