Megget Reservoir - Selkirk

Megget Reservoir is a man-made water body in the Megget valley in Ettrick Forest.  The 259 hectares (640 acres) reservoir is held back by the largest earth dam in Scotland. The reservoir collects water from the Tweedsmuir Hills, which is then conveyed 28 miles (45 km) via pipelines to Edinburgh. The pipelines are routed through the Manor Valley and the Meldon Hills, to Gladhouse Reservoir and Glencorse Reservoir in the Pentland Hills. The outflow from the reservoir is the Megget Water, which flows into St. Mary's Loch.  It has a capacity of 61,400,000 cubic metres (2.17×10⁹ cu ft), and a maximum water level of 334 metres (1,096 ft) above Ordnance Datum. The embankment is 56 metres (184 ft) high and its crest is 568 metres (1,864 ft) long.
