Loch Mhor is a general shallow body of water located a few miles southeast of Loch Ness, in Inverness, Highland, Scotland. Initially, the loch was divided in two separates lochs, Loch Garth, in the southwest, and Loch Farraline, in the northwest. It is used as a reservoir for the hydro-electric scheme and aluminium smelter at Foyers, but in order to do this the water level was raised, by joining the two lochs into one. The lochs are still separated by a causeway carrying a minor road. Loch Mhor is linked by the Foyers pumping station to Loch Ness by tunnels and pipes.
