River Earn
The River Earn (Scottish Gaelic: Uisge Èireann) in Scotland leaves Loch Earn at St Fillans and runs east through Strathearn, then east and south, joining the River Tay near Abernethy. The Earn is about 46 miles (74 km) long. It passes by Comrie, Crieff and Bridge of Earn.
The river is fast flowing, with many shoals, and is not navigable, even by small vessels. The surrounding land is generally flat and is occasionally subject to flooding. The Earn is popular with anglers and fishing permits are usually required.
Near to the River Earn lay the ancient Strageath Roman Camp. This camp was one of a series of camps used by the Romans to construct their invasion of the north; other notable camps in this chain are Ardoch, Stracathro, Battledykes, Raedykes and Normandykes.
