TheRiver Tweed, orTweed Water (Scottish Gaelic:Uisge Thuaidh/ɯʃgʲəhuəj/) is a river 97 miles (156 km)[1] long that flows east across theBorder region in Scotland and northern England.Tweed cloth derives its name from its association with the River Tweed.[2] The Tweed is one of the greatsalmon rivers of Britain and the only river in England where anEnvironment Agency rod licence is not required forangling. The river generates a large income for the local borders region, attracting anglers from all around the world.[3]
Tweed may represent anOld Brittonic name meaning "border".[4] A doubtful proposal is that the name is derived from a non-Celtic form of theIndo-European root*teuha- meaning "swell, grow powerful".[5]
The River Tweed flows primarily through the scenicBorders region of Scotland. Eastwards from the settlements on opposing banks ofBirgham andCarham it forms the historic boundary between Scotland and England.
It rises in the Lowther Hills atTweed's Well near the rising points of theClyde -- draining northwest (10 kilometres (6.2 mi) from the Tweed's Well) -- and theAnnan, draining south (1.9 kilometres (1.2 mi) from the Tweed's Well).
"Annan, Tweed and Clyde rise oot o’ ae hillside" is a saying from the Border region.[6] East ofKelso, it becomes a section of the eastern part of the border. Entering England, its lower reaches are inNorthumberland, where it enters theNorth Sea atBerwick-upon-Tweed. For only 7 kilometres of its course is it purely in England, and for 30 kilometres it is between England and Scotland.[7]
The upper parts of thecatchment of the Tweed in Scotland form the area known asTweeddale, part of which is protected as theUpper Tweeddale National Scenic Area, one of 40such areas in Scotland which are defined so as to identify areas of exceptional scenery and to ensure its protection from inappropriate development.[8]
