The Portmore Reservoir , also Portmore Loch , is a reservoir in the Scottish Council Area Scottish Borders .
geography
The lake is located at an altitude of 306 meters off the northwest flank of the Moorfoot Hills , more precisely the Dundreich , around three kilometers northeast of Eddleston . The much larger Gladhouse Reservoir is located around four kilometers to the northeast .
The main tributary is the stream Loch Burn , which flows into the south side and rises near the crest of the Dundreich. An earth wall on the north side dams the lake. Here the Loch Burn flows off, which joins the Tweeddale Burn to Fullarton Water downstream and feeds the Edgelaw Reservoir in Midlothian .
The Portmore Reservoir catchment area is 269 hectares . A storage volume of 2,086,397 cubic meters results from an average depth of 5.1 meters and a lake area of 41 hectares. The maximum depth of the Portmore Reservoir is 12.5 meters; its circumference three kilometers. The Portmore Reservoir finally drains into the Firth of Forth via Loch Burn, Fullarton Water, Edgelaw Reservoir, Redside Burn , South Esk and Esk .
history
Portmore Reservoir is part of a network of reservoirs along the North and South Esk rivers . It was built to supply Edinburgh in the 19th century after the older reservoirs in the Pentland Hills no longer met the requirements. The lake was dammed around 1878. It still serves as a drinking water supply today and is operated by Scottish Water . The engineer James Leslie planned the facility.
