Harperrig Reservoir was created in 1860 as part of a scheme to create a safe and reliable supply of drinking water for Edinburgh. The dam was raised in 1890 to provide a more reliable source of water to the mills downstream. The reservoir is known to be populated by otters as well as several species of wetland bird and the rare stonefly.

Beecraigs is actually a reservoir built between 1914 - 1918 by German prisoners of war. It was used to supply drinking water but was decommissioned as a reservoir in 1972. It became part of Beecraigs country park in 1980 and is now a popular fishing and walking destination. The path around the edge of the loch is a nice short walk mostly under tree cover.

A great alternative to the main track by going through the trees. You'll almost always end up taking a slightly different line in the trees as you weave through the patches of woodland by the side of water. Also a great spot to shelter from the wind if you want to stop for chow.

Open Water swimming spot, as well as a decent gravel track allowing you to connect to either the western Pentlands, or head north along the High Riggs, or if going east link to the saddle route over to Flotterstone, or through to Torphin to take you back into Edinburgh

So if you are into open water swimming, this is the favourite spot of the locals to go open swimming in this reservoir. There is a small beach to access the water and a good 100m run along to a land-bar that comes out into water.
