West Water Reservoir (sometimes Westwater Reservoir) is an artificial reservoir in the Pentland Hills, Scottish Borders, 3 kilometres (1.9 mi) west of West Linton, and 26 kilometres (16 mi) south west of Edinburgh. It is a drinking water reservoir for Edinburgh and the Lothians and is located 320 metres (1,050 ft) above sea level. It is an important site for wildfowl and is designated as a SSSI and a Ramsar site.
West Water reservoir was opened in 1969 with an earthwork dam on the West Water, a tributary of the Lyne Water which, in turn, is a tributary of the River Tweed. The reservoir has an area of 36.8 hectares (91 acres).[2] The reservoir is surrounded by the North Slipperfield Estate which manages the land for rough grazing and shooting.[3]
Erosion caused by the creation of the reservoir exposed an Early Bronze Age flat cist cemetery. When this was excavated the archaeologists found nine surviving cists. These contained remains from both inhumations and cremations and most of the deceased were sub-adult or young adults. Evidence of floral tributes was found in three burials and grave goods were also found.[4]
West Water reservoir is used by fly fishing anglers and is stocked with brown trout.[5] The fishing rights were transferred from Scottish Water to the local angling club in 2003.[6]
