Higher Swineshaw Reservoir is the highest reservoir in a series of four in the Brushes Valley above Stalybridge in Greater Manchester. It was built in the 19th century by the corporations of Ashton-under-Lyne and Stalybridge to provide a supply of safe drinking water, one of four reservoirs authorised by the Ashton-under-Lyne and Stalybridge (Corporations) Waterworks Act 1864 (27 & 28 Vict. c. xlvii). Though the reservoir and its watershed are totally in Greater Manchester it is within a mile of the Derbyshire border. It is owned and operated by United Utilities.
The reservoir dam consists of a clay core within an earth embankment. The Peak District Boundary Walk runs across the dam on the south side of the reservoir.
