Sheepstor Dam, together with Burrator Dam, impounds Burrator Reservoir 13km north east of Plymouth and superseded Drake's Leat as the water supply for the city. The dam is situated on a ridge between the River Meavy and Sheepstor Brook, to the east of Burrator Dam, and closes the gap between the Sheepstor and Burrator hills.
Sheepstor Dam is an earth embankment 143m long with a puddled clay core, and concrete slabs on the reservoir side and grass on its downstream side. Its crest is just 7m above original ground level, although the 1.5m wide concrete cut-off wall had to be extended 32m down to reach solid rock.
Work on the two dams, the reservoir and a pipeline link to Roborough service reservoir were authorised by the Plymouth Corporation Act of 9th June 1893. Sheepstor Dam was designed by Edward Sandeman, Water Engineer to the corporation, who also supervised its construction by direct labour. Work began in 1894 and was completed in 1898 at a cost of £24,000, with an official opening ceremony by Mayor J.T. Bond on 21st September 1898.
Between December 1923 and 1928, the damís crest level was raised by 3m. The work was government-funded as part of an unemployment relief programme, and with the corresponding raising of Burrator Dam, increased the capacity of Burrator Reservoir by some 35% to 4,660 million litres.
