The River Leven (Scottish Gaelic: Uisge Leamhna) is a stretch of water in West Dunbartonshire, Scotland, flowing from Loch Lomond in the North to the River Clyde in the South. The river is about 10 kilometres long. It is very popular with salmon and sea trout anglers, trying to catch one of these migratory fish going up to Loch Lomond.
