The southern of Glen Lyon's two hydro power reservoirs.

Access gained by single-track road which ends just by the dam at NN 453 416. The loch, shaped like a Y lying on its side, splits at about 4.5km in from the east. The NW branch continues on about 1.5km leading to the Allt Meurain in Gleann Meurain and the SW branch continues on about 4.5 km, leading eventually to the mouths of the Abhainn Ghlas and the Allt Tarabhan.

A pleasant spot to access various hills and narrow glens from or to just enjoy the views of the terrain rising all around.
