Burrator Reservoir is a reservoir on the south side of Dartmoor in the English county of Devon. It is one of a number of reservoirs and dams that were built over the course of the 19th and 20th centuries in the area now covered by Dartmoor National Park to supply drinking water to the city of Plymouth and other rapidly growing towns in the surrounding lowlands. Burrator Reservoir was completed in 1898, and the reservoir was expanded in 1929.
