Dove Stone Reservoir

Dove Stone Reservoir lies at the convergence of the valleys of the Greenfield and Chew Brooks above the village of Greenfield, on Saddleworth Moor in Greater Manchester, England. Historically part of the West Riding of Yorkshire, the reservoir is on the western edge of the Peak District National Park. It supplies drinking water to the surrounding area and is a tourist attraction, providing several walks amongst picturesque landscapes.

John Platt of Oldham built a Neo-Gothic mansion at Ashway Gap on the south side of the valley in 1850. It was used as a shooting lodge but after his brother James's death in a shooting accident on the moor above it, the house was left empty. The house was later acquired by the Ashton-under-Lyne, Stalybridge and Dukinfield (District) Waterworks Joint Committee. Boundary stones demarcating the extent of the estate are located at intervals along the footpaths along the south side of the reservoir. During World War I the waterworks board offered the house for use as a hospital. It was demolished in 1981.

On the northern end of Dove Stone Moss, above the Ashway Gap, the Ashway Stone is a memorial to James Platt, MP for Oldham, who was killed by an accidental discharge of the gun of Josiah Radcliffe, the Mayor of Oldham.

The reservoir scheme in the Greenfield Valley and Chew Valley by the Ashton-Under-Lyne, Stalybridge and Dukinfield (District) Waterworks Joint Committee commenced in 1870. The scheme was completed with Dove Stone Reservoir in 1968 to collect water from the surrounding moorland. The main contractor was A. E. Farr (Civil Engineers) of Westbury, Wiltshire. Its construction was opposed by local mill owners, who claimed that damming the river would cut off their water supply. As a result, a tunnel was built higher up in the hillside to bypass the reservoir.

During a visit in 1981 to attend the wedding of Prince Charles and Princess Diana, King Taufa'ahau Tupou IV of Tonga visited Dove Stone Reservoir. To commemorate the visit, a carved stone has been set into the dam wall of the Yeoman Hey Reservoir.

In December 2015, a man who travelled from London to Manchester and walked to a location close to the reservoir, died on the Chew Track. The unknown individual was initially nicknamed "Neil Dovestones" by pathologists, until he was identified as David Lytton in January 2017.

The reservoir lies at the convergence of the valleys of the Greenfield and Chew Brooks above Greenfield in the north west edge of the Peak District's Dark Peak area. It is the lowest and largest of three reservoirs in the Greenfield Valley. Above it are the Yeoman Hey, built in 1880, and Greenfield Reservoirs. Chew Reservoir is in the upper Chew Valley and at 1,600 feet (490 metres) above sea level was the highest reservoir in the British Isles when it was built in 1914. The reservoirs are surrounded by moorland and, above the valley, high rocky outcrops.

The A635 road to Holmfirth passes to the west and north of the reservoirs.
