Loch Lyon (Scottish Gaelic, Loch Lìobhann) is a freshwater loch in Glen Lyon, located in Perthshire, Scotland, which feeds the River Lyon, a tributary of the River Tay. The original natural loch was much expanded by a hydro-electric dam, part of the North of Scotland Hydro-Electric Board's Breadalbane scheme.
