Before the reservoir was built, water was taken to Devonport via this eponymous leat. It was built in the 1790s to take water to Devonport and its Royal Naval dockyard. Plymouth was supplied by Drake's Leat. Both leats were 'retired' when the reservoir was built and Devonport was incorporated into the City of Plymouth (along with Stonehouse).
Over its original 28 mile length, the leat fell from a height of about 1390 feet to a level of about 130 feet i.e. it descended 1260 feet, giving it an average drop of 1 foot in 117 feet, less than a 1% slope. Quite an engineering feat over that distance, don't you think? And this gentle slope means that following a leat is always fairly level walking. |
